INTRODUCTION 


This monograph is a study of the avifauna of that part of New 
Guinea known as the Eastern Highlands, i.e. the Central Range be- 
tween longitudes 143°E and 146°E and above an altitude of 1,350 ft. 
The discussion is based initially on my collections and studies made 
during four expeditions to New Guinea between 1964 and 1969, but 
the records of other workers in the Eastern Highlands are also sum- 
marized. The first part of the text (I, pp. 3-15) gives a brief synopsis 
of the ornithological exploration of the Eastern Highlands and de- 
scribes my collecting itineraries, methods, and localities. ‘The second 
part (II, pp. 17-94) analyses some features of general ecological and 
evolutionary interest in the avifauna of the Eastern Highlands: 
patchiness of distribution, ecological sorting mechanisms (niche differ- 
ences between congeners), a speciation mechanism in montane birds, 
zoogeographical affinities, altitudinal distribution, the breeding non- 
forest avifauna, migration, bird assemblages in fruiting and flowering 
trees, breeding patterns, and bird classification by New Guinea natives. 
A summary of this second part is given on pp. 92-94. The third part 
(II, pp. 95-412) consists of individual accounts of the 354 species 
recorded to date from the Eastern Highlands. ‘This is followed by a 
list of relevant literature (IV, pp. 413-419) and an index (V, pp. 421- 
438). 

‘The manuscript was accepted by the Nuttall Ornithological Club 
on 20 September 1971.

ORNITHOLOGICAL STUDIES IN THE 
EASTERN HIGHLANDS 


SOURCES OF INFORMATION 


The backbone of the island of New Guinea (Maps | and 2) is 
formed by a central mountain range which rises to nearly 17,000 ft 
and which runs uninterrupted for about 1,000 miles from near the 
southeastern tip of New Guinea west to the head of Geelvink Bay 
(longitude 135°E). There are no known north-south passes under 
5,000 ft in the Central Range. In two areas, namely, in the Eastern 
Highlands and in the Baliem and Haga Valleys of the Snow Mountains 
of western New Guinea, the Central Range broadens into a system 
of valleys with dense human populations. New Guinea’s remaining 
mountains are the mountains of the Vogelkop Peninsula in the 
far west, and a series of isolated ranges or “mountain islands” along 
the north coast (Van Rees Mountains, Cyclops Mountains, North 
Coastal Range, Adelbert Mountains, and mountains of the Huon 
Peninsula) which are separated from the Central Range by lowland 
basins. In this monograph the term “Eastern Highlands” is arbitrarily 
taken to mean that portion of the Central Range between longitudes 
143°E and 146°E. These limits are chosen partly for practical reasons 
arising from availability of information, but they also correspond ap- 
proximately to a natural zoogeographic unit which is weakly distinct 
from the portions of the Central Range farther to the west and to the 
east, as discussed on pp. 46-48. Coverage in this monograph is further 
restricted to elevations above 1,350 ft, my lowest collecting station. 

The area of New Guinea covered (Map 3) thus extends approxi- 
mately from ‘Tari in the west to Kainantu 200 miles farther east, and 
from the Schrader Range in the north to Lake Kutubu and Mt. 
Karimui 120 miles farther south. ‘The highest peak of this area is Mt. 
Wilhelm (ca. 15,000 ft), with numerous other peaks exceeding 12,000 ft 
(e.g., Mt. Hagen, Mt. Giluwe, and Mt. Michael). The drainage is by 
tributaries of the Sepik and Ramu Rivers in the north, and by 
tributaries of the Purari and Kikori Rivers in the south. The principal 
towns include Goroka, Mt. Hagen, Kainantu, ee Mendi, Minj, 
and Wabag. The zoogeographical area which I call “Eastern High- 
lands” includes, but is larger than, the political subdivision of the 
‘Territory of Papua and New Guinea called the “Eastern Highlands 
District.” 

The following sources of information concerning the avifauna of 
the Eastern Highlands were available to me:

STUDIES IN THE EASTERN HIGHLANDS 


were carried out independently by three workers in the early 1950's in 
the Wahgi Valley and surrounding mountains (see Map 3 for these 
and other collecting stations in the Eastern Highlands). E. ‘T. Gilliard 
of the American Museum of Natural History led expeditions in 1950 
and 1952, the results of which were reported by Mayr and Gilliard 
(1954). Gyldenstolpe (1955) described the collections he made for the 
Stockholm Museum in 1951. Sims (1956) analysed birds collected by 
Shaw-Mayer for the British Museum (Natural History) in 1950 and 
1951. Almost all the material of these three collectors was obtained at 
elevations above 5,000 ft. ‘Their surveys of the forest at higher eleva- 
tions were sufficiently exhaustive that subsequent workers have been 
able to add only two species to the forest avifauna breeding in the 
Eastern Highlands above 6,000 ft. 

In the Schrader Range on the northern rim of the Eastern High- 
lands a small but important early collection on the 6,700-foot Schrader- 
berg was made in 1913 by Biirgers as part of the Sepik River Expedi- 
tion of the German colonial administration. It was studied by Strese- 
mann (1923). ‘The remaining collections of this large expedition were 
obtained at low elevations along the Sepik River and on mountains 
(Hunsteinspitze, Lordberg, Etappenberg, Maanderberg) farther to the 
west, which fall outside the area covered by this monograph. Another 
collection in the Schrader Range was obtained by E. T. Gilliard in 
1964 at 5,000-8,600 ft and was discussed by Gilliard and LeCroy (1968). 

Collections for the Commonwealth Scientific and Industrial Re- 
search Organization of Australia (C.S.I.R.O.) were made by Schodde 
in 1961 at Lake Kutubu (2,450 ft) and Mt. Giluwe (ca. 5,900-11,500 ft) 
and by Hitchcock in 1963 in the Kubor Range (ca. 6,400-12,000 ft). 
The Lake Kutubu collection was described by Schodde and Hitchcock 
(1968), while the Kubor collection was briefly discussed by Hitchcock 
(1964), who kindly provided me with further unpublished records 
based on it. 

Unpublished information from other observers was also available 
during the preparation of this report. Dr. R. N. H. Bulmer generously 
provided detailed summaries of his extensive unpublished observations 
between ca. 3,000 and 12,000 ft, principally from two areas: the 
Kaironk Valley of the Schrader Range, and the Kyaka area from Baiyer 
River to the northern slopes of Mt. Hagen. Major H. L. Bell furnished 
records from several localities. ‘The New Guinea Bird Society News- 
letter, published monthly since 1965, was the source of some additional 
records by other naturalists resident in New Guinea. 

My studies were carried out in the course of four expeditions (1964, 
1965, 1966, 1969) to the southeastern part of the Eastern Highlands 
at elevations between 1,350 and 12,300 ft. Most of the new distribu- 
tional records and material of taxonomic interest were obtained below 
5,000 ft, because the nearest localities at which the hill forest (2,000- 


STUDIES IN THE EASTERN HIGHLANDS 


5,000 ft) avifauna of the southern watershed of the Central Range had 
been exhaustively surveyed were 400 miles to the west (Snow Moun- 
tains) and 150 miles to the east (Wharton Range). Also, previous 
taxonomic publications on Eastern Highlands material discussed little 
material under 5,000 ft, except for the report of Schodde and Hitch- 
cock (1968). A summary of my itineraries, methods, and collecting 
stations follows. 


ITINERARIES 


The 1964 expedition was conducted jointly with Dr. John W. Ter- 
borgh. From 9 June to 28 June we worked in the vicinity of Okapa, 
principally at the villages of Miarosa and Awande (Map 3). Between 
29 June and 19 July we surveyed the avifauna of Mt. Michael, in- 
cluding the collecting stations of Lufa and Mengino. On 20 July we 
set out overland from Mengino through the territory of the Gimi 
people for the Karimui Basin, which ‘Verborgh reached on 27 July. 
I stopped en route to observe at a campsite on the Sena River between 
25 and 28 July, and arrived at Karimui on 29 July. From then until 
17 August we remained at Karimui Patrol Post, surveying the avi- 
fauna of the Karimui Basin. We returned to Okapa for the period 
18-27 August, spending part of this period at the nearby Okasa forest. 

In 1965 I began observing in the Okapa area on 13 June and worked 
there until 27 June, dividing the time between the village of Awande 
and the Okasa forest. he remainder of the expedition, which lasted 
until 15 September, was spent in the Karimui area. Studies were 
carried out at Karimui Patrol Post itself 1-5 July, 10-18 July, 2-7 
August, and 11-15 September. Bomai was reached by Cessna airplane 
and observations made there between 6 and 9 July. My lowest-altitude 
collecting station was Soliabeda, which I reached overland in two and 
one-half days and where I worked from 19 July to 1 August. ‘The period 
from 8 August to 9 September was devoted to altitudinal censuses on 
the west peak of Mt. Karimui. 

The 1966 expedition was mainly concerned with exploring the 
North Coastal Range (Diamond, 1967b, 1968, 1969) and falls outside 
the scope of this monograph. No collections were obtained in the 
Eastern Highlands, but some observations were made at Karimui, 
Okapa, and Goroka on 20-24 June and 14-15 September. During the 
1969 expedition, studies were made at Astrolabe Bay, Karkar and 
Bagabag Islands, New Britain, and Mt. Albert-Edward in southeastern 
New Guinea, all lying outside the Eastern Highlands. However, the 
avifauna of Mt. Albert-Edward is very similar at the species level to 
that of the Eastern Highlands, and analyses of stomach contents and 
some behavioral observations from Mt. Albert-Edward are cited in 
this monograph.

In order to leave much of my time free for field observations, vir- 
tually all specimens were collected and prepared by Eastern Highlands 
natives: Paran, Koreko, and Esa of the Fore people, Gumini and Uro 
of the Gimi people, and Kariniga and Omwai of the Karimui people. 
Collecting was carried out with shotguns and with mistnets. I ex- 
amined many additional specimens that had been obtained by local 
people with bow and arrow, snares, sticks, and other less conventional 
means. In the afternoon or evening I supervised the preparation of 
specimens by Highlands assistants, sexing each specimen by dissection 
and noting the condition of the gonads. In 1965, but not in 1964, 
specimens were weighed prior to preparation. Most specimens were 
prepared as skins, but some were made into skeletons or preserved in 
formalin. Collections of frogs, lizards, snakes, and mammals (mostly 
rodents and mistnetted bats, but also some marsupials) were brought 
back in formalin. The bird skins are divided between the American 
Museum of Natural History, the Harvard Museum of Comparative 
Zoology, and the Los Angeles County Museum of Natural History; 
all mammals are at the first-named institution, all birds in formalin 
at Harvard; the frogs, lizards, and snakes are divided between the 
American Museum of Natural History and Harvard; and the bird 
skeletons are divided between these two institutions and the United 
States National Museum. ‘Taxonomic evaluation of all the collected 
bird material was undertaken in the Bird Department of the Ameri- 
can Museum of Natural History, where the most extensive collection 
of New Guinea birds is located. Some comparisons were also under- 
taken at the Museum of Comparative Zoology. 

Most mornings and parts of the afternoons were used for field ob- 
servations. My observations were mainly devoted to determining, as 
accurately as possible, the altitudinal ranges in undisturbed forest, to 
identifying songs and calls, and to estimating relative abundances of 
species by crude censusing techniques. ‘The most exact altitudinal 
records were obtained on the west ridge of Mt. Karimui, which was 
completely covered by undisturbed forest. ‘There were no man-made 
clearings within two miles of this ridge. Visible evidence and reports 
of local informants indicated that the summit of the ridge had not 
been climbed previously and that the lower parts of the ridge were 
visited only infrequently by native hunters. We made a footpath along 
the crest of the ridge from its base at 4,000 ft to the summit at 8,165 
ft; made horizontal paths to divide the mountain into eight altitudinal 
zones of about 500 vertical feet each; selected convenient reference 
marks to divide each zone into subzones ranging in vertical extension 
from 60 to 200 ft; and placed camps at the top of Zone 1 (4,200 ft), 
at the junction of Zones 2 and 3 (4,750 ft), at the junction of Zones

STUDIES IN THE EASTERN HIGHLANDS 


3 and 4 (5,390 ft), and at the junction of Zones 5 and 6 (6,500 ft). The 
altitude of each reference point was read to £5 ft on an aviation 
altimeter on which the standard barometric pressure was set to 29.92 
inches. “Phe average of numerous readings on different days under 
varying atmospheric conditions was calculated for each point, since 
daily standard barometer r sadings on Mt. Karimui were, of course, 
unavailable. Upon retrieving a bird the collectors numbered the wrap- 
ping paper of each specimen to indicate the subzone in which it had 
been taken. By frequently noting the contents of the nets before my 
assistants later came to empty them, I was able to determine that their 
subzone assignments were completely reliable. I conducted daily cen- 
suses of each subzone in turn, and recorded exact elevations whenever 
a bird was encountered near a limit of its species range. An average 
of four days was devoted to collecting and censusing in each of the 
eight zones, and an average of a week was spent living at each of the 
four camps. Thus, the relative abundance at vertical intervals of 60 
to 200 ft was estimated for all species present on Mt. Karimui, and 
the limits of some species (cf., Crateroscelis murina and C. robusta, 
p. 27) were determined exactly. 

Crude censuses of relative abundance (not of absolute abundance per 
acre) were conducted by counting each bird heard or seen within a 
horizontal distance of about 50 yards during several hours of observa- 
tions each day. If a song was heard several times from the same locus, 
suggesting that it came from the same individual, it was counted only 
once. Individuals apparently more than about 50 yards away were 
not counted, in order to reduce the extent to which the abundance 
of conspicuous or noisy species might be overestimated. ‘The number 
of individuals of a given species censused was divided by the total 
number of individuals of all species censused in order to obtain one 
estimate of the species’ relative abundance, expressed as a percentage 
of the whole avifauna. A second estimate was derived from collected 
specimens, by dividing the number of individuals of a given species 
collected by the total number of all birds collected. ‘These two esti- 
mates were then averaged, for each species and for each subzone or 
collecting locality, to yield the relative abundances which will be cited 
in the individual species accounts. For instance, the statement that a 
given species “accounts for 2% of the local avifauna” means that two 
of every 100 birds locally present are estimated to be of that species. 
The relative abundances of the commonest species at a locality were 
rarely above 10%, and were generally in the range 4-10%. ‘There were 
about 21 species at Karimui Patrol Post (3,650 ft), and about 15 in 
Zone 3 of Mt. Karimui (4,750-5,390 ft), with relative abundances 
greater than 1%. 

These crude estimates of local relative abundance are obviously 
subject to systematic errors because of the methods used to derive 
them. Species which rarely sing, or whose songs I failed to determine, 


10 


STUDIES IN THE EASTERN HIGHLANDS 


or which tend to stay out of sight, were underestimated in field cen- 
suses. Middlestory and upperstory species which are infrequently or 
never caught in mistnets were underestimated in the collections. Some 
protected species which my assistants were instructed not to collect 
beyond a certain number (birds of paradise, bowerbirds, and the large 
cockatoos) were underestimated in shotgun collections, but many of 
these, fortunately, are noisy birds which were inevitably overestimated 
in my field censuses. However, the combined estimate from censuses 
and collecting should provide at least tentative first estimates of rela- 
tive abundance. Comparisons of the relative abundance of the same 
species at two different localities or altitudes should be freer from 
distortion, since the same systematic errors would affect the species 
at both localities. 


DESCRIPTIONS OF COLLECTING LOCALITIES 


General Remarks 


Botanical descriptions of parts of the Eastern Highlands have been 
given by Brass (1959), Hitchcock (1964), and Schodde and Hitchcock 
(1968), and of montane vegetation in other parts of New Guinea by 
Brass (1941), Archbold, Rand, and Brass (1942), and Gilliard and 
LeCroy (1961). Briefly, the original vegetation over almost the whole 
area of the Eastern Highlands was forest up to timberline at about 
11,500 ft, above which alpine grassland takes over. ‘The total area oc- 
cupied by natural non-forest habitats between 1,000 ft and timberline 
is extremely small. It consists only of strips along the few lakes (Lake 
Kutubu, Lake ‘Tebera, Lake Kandep) and numerous small rivers and 
streams in this altitudinal range, plus occasional landslide, earthquake, 
and tree-fall areas on mountain slopes. The clearing of the forest for 
agricultural purposes has greatly expanded these open habitats. ‘Voday, 
because of dense native population, the Eastern Highlands contain 
the most extensive areas of (secondary) midmontane grassland in New 
Guinea. 

The forest itself gradually changes in composition with altitude, the 
general succession being lowland rainforest at the lowest elevations, 
midmontane forest dominated by oaks (Castanopsis, Quercus), forests 
dominated by southern beeches (Nothofagus) at higher elevations, and 
subalpine forest and shrubbery with numerous conifers (Podocarpus, 
Libocedrus). Perhaps the most striking change in forest physiognomy 
occurs at what may conveniently be termed the moss level. ‘The upper 
elevations of New Guinea mountains are shrouded much of the time 
in standing banks of clouds. Within this moist and poorly lit zone the 
forest is stunted, and thick layers of moss cover much of the ground, 
trunks, and branches. The lower limit of this heavily mossed zone, 
which is said to coincide with the lower limit of the cloud banks, is 
sometimes sufficiently distinct that it can be meaningfully defined to 


11 


STUDIES IN THE EASTERN HIGHLANDS 


within 50 vertical feet. Its elevation varies considerably from mountain 
to mountain, depending upon local cloud conditions. This moss level 
occurs at about 6,500 ft on Mt. Karimui’s west mdse, abr 4,500 tt on 
Mt. Karimui’s east ridge, at 8,700 ft on Mt. Michael, and at some 
undetermined altitude about 7,500 ft in the Okapa area. Several birds, 
such as Ptiloprora guisei, Oreocharis arfaki, Peneothello sigillatus, and 
Lophorina (Pteridophora) alberti, have lower altitudinal limits which 
correlate approximately with the moss level, while some other species 
(p. 67) have ceilings at the moss level. 
Specific Localities 

Okapa area.—Collecting localities were Okapa Patrol Post (6,600 ft); 
Awande (6,000 ft), a native village two miles east of Okapa; Miarosa 
(5,800 ft), a native village two miles east of Okapa and one mile south 
of Awande; and Okasa, a forestry camp near a village of the same 
name, nine miles south of Okapa. The highest collecting elevation in 
this area was at 7,500 ft on the ridge separating Miarosa from Awande, 
and the lowest was at 3,550 ft on a small river below Okasa. This area 
is inhabited by the Fore people, who have achieved medical promi- 
nence through kuru or “laughing sickness” (Gajdusek and Zigas, 1957), 
an incurable and invariably fatal neurological disease which is largely 
restricted to the Fore and accounts for a high percentage of their 
deaths. Much of the area around Okapa, Awande, and Miarosa has 
been cleared for agriculture and exists as gardens, grassland, or second- 
erowth, but the hill slopes behind Miarosa and Awande remain with 
their original cover of midmontane forest. At 7,500 ft there is still little 
moss in the forest. Correlated with this, Oreocharis arfaki and Peneo- 
thello sigillatus are absent, and Ptiloprora guisei is very rare in the 
Okapa area. Most collecting at Okasa was done between 3,550 and 
4,250 ft in a forest with magnificent tall Araucaria pines. ‘This forest 
is a reservoir of cerebral malaria and is presently uninhabited, but 
large expanses of grassland around it testify to a formerly dense native 
population. 

Mt. Michael area.—Collecting localities were Mt. Michael itself, an 
isolated 12,300-foot peak forested above 7,000 ft, below which altitude 
the forest has been largely cleared; Lufa Patrol Post at 6,300 ft on the 
north slope of Mt. Michael, situated in an area which has been largely 
cleared; and Mengino, a village at 6,150 ft on the west slope of Mt. 
Michael. Our principal camp was located in tall forest at 8,000 ft on 
the northwest side of Mt. Michael, with a subsidiary camp in stunted 
subalpine forest at 10,200 ft. Heavily mossed conditions are first en- 
countered at 8,700 ft, and alpine grassland at 11,200 ft, but patches 
and tongues of shrubbery in the alpine grassland are still found near 
the summit at 12,300 ft. Terborgh and I reached alpine grassland and 
the summit only on one day (10 July 1964), so that my experience of 
alpine grassland in the Eastern Highlands is limited. Collecting at 


12 


STUDIES IN THE EASTERN HIGHLANDS 


Mengino extended from the village at 6,150 ft down to a river at 4,600 
ft, in partly cut forest interspersed with second-growth and gardens. 

Gimi territory —The area between Mengino and the east rim of the 
Karimui Basin is hilly and lies between 4,200 and 6,500 ft. Second- 
erowth and gardens are found around several small villages of the 
Gimi people, but most of the area is still forested. Little time was 
available for collecting in this area. However, in passing through a 
small patch of mossy forest at about 6,000 ft we met Pliloprora guiset 
again, which was absent at the same and even higher elevations else- 
where in areas with little mossing. 

Karimui Basin —Most of the Eastern Highlands consists of rugged 
and steep ridges and mountains. ‘The Karimui Basin, a volcanic plain 
on the north side of Mt. Karimui, is of interest as one of the few large 
flat expanses within the Eastern Highlands. ‘The basin floor is at about 
3,500 ft, has no hills, and is flat except for a few narrow stream gorges. 
As shown by several aerial reconnaissance flights, which I undertook in 
1965, the basin is effectively sealed off from the rest of the Eastern 
Highlands by a ring of mountains which rises to about 8,400 ft in 
the central peak of Mt. Karimui and which stands at least 1,000 ft (in 
most places much higher) above the basin floor on all sides except 
where pierced by narrow river gorges. Thus, the Karimui Basin is an 
island of tropical habitat isolated within the Eastern Highlands, a 
fact which is reflected both in its endemic bird forms and in the 
unusual composition of its avifauna (pp. 53-56). At the time of my 
studies most of the basin floor was still covered by rainforest, which 
unfortunately is rapidly being cleared in the vicinity of villages. In its 
vegetational structure this basin forest is typical of the rainforest of 
the flat lowlands near sea level, e.g., in the presence of emergent trees 
up to 200 ft tall (“A story” in the sense of Richards (1952)), and differs 
from the hill forest encountered at the same elevation at most other 
localities in New Guinea. Collecting localities on the basin floor were 
Karimui Patrol Post at 3,650 ft, henceforth simply called Karimui; 
and Bomai, a small airstrip and native village at 3,250 ft about 12 
miles west of Karimui. ‘The locality “Sena River” refers to a camp I 
made in undisturbed forest beside a small stream at 4,500 ft. This 
camp lay 15 miles east of Karimui and within the basin but part way 
up its eastern wall. Soliabeda is a native village at 2,000 ft, nine miles 
southeast of Karimui and beyond Mt. Karimui, i.e., outside of the 
basin. ‘The village of Soliabeda was only a few years old, so that the 
area of land which had been cleared for gardens was still small. The 
terrain around Soliabeda is hilly, in contrast to the nearby Karimui 
Basin. Below the village of Soliabeda the Wi River, flowing at 1,350 
ft, represented the lowest altitude I reached in the Eastern Highlands. 
Finally, collections were made on the west ridge of Mt. Karimui itself, 
which was reached from the village of Iogoramalu, about six miles 
west of Karimui Patrol Post. As described on p. 9, the ridge was 


13 


STUDIES IN THE EASTERN HIGHLANDS 


divided into eight altitudinal zones with the following limits: Zone 1, 
4,000-4,200 ft; Zone 2, 4,400-4,750 ft; Zone 3, 4,750-5,390 ft; Zone 4, 
5,390-5,960 ft; Zone 5, 5,960-6,500 ft; Zone 6, 6,500-7,080 ft; Zone 7, 
7,080-7,620 ft; Zone 8, 7,620 ft to the summit of the mdee at 365 it 
The highest peak of Mt. Karimui is a few hundred feet higher than 
the summit of this west ridge but is separated from it by a narrow 
vertical-walled chasm several thousand feet deep and hence was in- 
accessible to me. Zone | was still on the gently sloping edge of the basin 
floor, while Zones 2 through 8 were on the ridge which rises con- 
tinuously and steeply from the top of Zone | to the summit. A well- 
defined moss level occurrs at 6,500 ft, above which the stunted summit 
forest is a three-dimensional maze of fallen branches, low trees, and 
bushes, all overgrown with cold, wet moss. 

Goroka.—A few observations were made at this town, which is one 
of the principal commercial centers in the Eastern Highlands, but no 
specimens were collected. The elevation is 5,140 ft. All land in the 
vicinity has been cleared, and no primary forest remains.

SOME GENERAL FEATURES OF THE EASTERN 
HIGHLANDS AVIFAUNA 


PATCHINESS OF DISTRIBUTION 


“Drop-outs”’ in the Eastern Highlands 


The breeding avifauna of montane forest and alpine grassland of 
the Eastern Highlands must now be considered well-explored ornitho- 
logically. Since the surveys of Gilliard, Gyldenstolpe, and Shaw-Mayer 
in the years 1950-1952, only two forest species appear to have been 
added to the list of birds breeding or presumed breeding at elevations 
above 6,000 ft, viz., the honeyeater Piiloprora meekiana and the man- 
nikin Erythrura papuana. Most species breeding above 6,000 ft in the 
Eastern Highlands have been recorded or collected there on at least 
two separate instances, the sole exceptions being Pachycephala tene- 
brosa and Ptiloprora meekiana, which are known in the Eastern High- 
lands from a single specimen each. ‘There are undoubtedly further 
breeding species to be recorded from the hill forests below 6,000 ft and 
from grassland and disturbed areas above this elevation. More non- 
breeding migrants and vagrants from the lowlands also remain to be 
discovered. However, the addition of more than one or two species 
to the breeding avifauna of undisturbed forest above 6,000 ft is un- 
likely. 

For these reasons it is significant that there are nine species that 
have been recorded from the Central Range to the east and west of the 
Eastern Highlands but not in the Eastern Highlands, even though the 
Eastern Highlands provide suitable habitats. A few of these apparent 
“drop-outs” may still turn up, but most of them will probably prove 
to be absent. ‘hese absences, and several related phenomena involving 
distributional patchiness in New Guinea, require detailed discussion 
because of their evolutionary and zoogeographical significance. ‘The 
nine apparent “drop-outs” are: 

Mieraaetus morphnoides, Little Eagle (Accipitridae); a rare species 
in New Guinea, recorded to date from the Central Range in western 
New Guinea (Utakwa River, Baliem Valley, Idenburg River), the 
Central Range in southeastern New Guinea (Aroa River, Hydro- 
grapher Range, Sogeri District, Wau), two of the “north mountain 
islands” (Adelbert Mountains, Huon Peninsula), and the lowlands 
near Lae. Most of these records are from between 2,000 and 6,000 ft. 

Coracina lineata, Barred Graybird (Campephagidae); a patchily dis- 
tributed but locally common inhabitant of hill forest between 2,000 
and 4,000 ft in the mountains of the Vogelkop, southeastern New

Guinea, and three of the “north mountain islands’’ (North Coastal 
Range, Adelbert Mountains, Huon Peninsula). 

Amalocichla sclateriana, Greater New Guinea Thrush (Purdinae); 
forests of the Central Range between 8,000 and 12,000 ft in western 
and southeastern New Guinea. 

Orthonyx temminckit, Logrunner (Orthonychinae); forest at 4,000- 
10,000 ft on the Central Range in western and southeastern New 
Guinea and on the Vogelkop. 

Macgregoria pulchra, MacGregor’s Bird of Paradise (Paradisaeidae); 
conspicuous and fairly common in high altitude forest (9,000-13,000 ft) 
of the Central Range in west New Guinea, probably at ‘Velefolmin, 
and in southeastern New Guinea. It strains one’s credulity to suppose 
that Macgregoria pulchra could have escaped detection if it occurred 
in the Eastern Highlands. Not only is it conspicuous, but most New 
Guinea ornithologists have paid particular attention to birds of para- 
dise. Gilliard, Bulmer, I, and others made a habit of exhaustively 
quizzing local natives and would surely have learned of Macgregoria 
in this fashion, as Gilliard did at ‘Velefolmin (Gilliard and LeCroy, 
HYG, p. LO and p.-64). 

Climacteris lewcophaea,! White-throated ‘Tree Creeper (Climacteri- 
dae or (?) Certhiidae); the sole species of creeper in New Guinea; 
forest from 5,000 to 10,000 ft on the Central Range (western and 
southeastern New Guinea, Telefolmin) and the Vogelkop. 

Ptiloprora plumbea, Leaden Honeyeater (Meliphagidae); a rare in- 
habitant of the Central Range in forest at 4,000-6,000 ft (Utakwa River 
of western New Guinea, ‘Velefolmin, and southeastern New Guinea). 

Melanocharis arfakiana, Obscure Berrypecker (Dicaeidae); the sec- 
ond rarest New Guinea bird, known from two specimens, one taken 
on the Vogelkop at the western tip of New Guinea in 1867, and the 
other taken 1,000 miles to the east in 1933 at 3,000 ft 1n southeastern 
New Guinea. 

Lonchura monticola and L. montana, Alpine Mannikin (Estrildidae), 
a superspecies; alpine grassland at 9,000-14,000 ft in western and south- 
eastern New Guinea, where it is common and occurs in flocks of up to 
50 birds. ‘The only other ecologically related estrildid in New Guinea, 
Oreostruthus fuliginosus, is uncommon and restricted to the edge be- 
tween forest and alpine grassland. ‘The alpine grasslands of Mts. 
Hagen, Wilhelm, and Giluwe have been explored by several collectors, 
and this conspicuous species could hardly have been missed if present. 

Of these nine “drop-outs,” the evidence is strongest for the absence 
of Macgregoria pulchra and Lonchura monticola; nearly as strong for 
Amalocichla sclateriana, Orthonyx temmincku, and Climacteris leuco- 
phaea; less strong for Hieraaetus morphnoides, Coracina lineata, and 
Ptiloprora plumbea; and inadequate concerning the mysterious Me-

Map 4. Distribution of Climacteris leucophaea, the White-throated Tree Creeper. 
This species is present on the Vogelkop and on the western and southeastern por- 
tions of the Central Range but is absent from the Eastern Highlands, so that its 
distribution is discontinuous despite the continuous expanse of montane habitat 
on the Central Range. 


lanocharis arfakiana. Since some of these drop-outs are uncommon or 
rare, the obvious first question to ask is whether there has been enough 
work in the Eastern Highlands to justify attaching significance to the 
apparent absences. The following comparison shows that the ornitho- 
logical exploration of the Eastern Highlands would have been more 
than adequate to detect their presence in most cases. In southeastern 
New Guinea the First Archbold Expedition collected 3,200 birds in 
1933-1934; the collection included eight of the nine species that drop 
out in the Eastern Highlands. In western New Guinea the Third 
Archbold Expedition collected 4,846 birds in 1938-1939; the collection 
included six of the nine Eastern Highlands drop-outs. ‘The total num- 
ber of bird specimens collected to date in the Eastern Highlands is 
considerably larger, viz., about 7,500, of which a higher proportion 
came from medium and high altitudes (where most of the drop-outs 
would be found) than in the case of the Archbold Expeditions. In 
addition, workers in the Eastern Highlands have been able to supple- 
ment their own observations with far more information gathered from 
local natives than did the Archbold Expeditions. For instance, my 
Fore and Daribi assistants gave me detailed descriptions of all the 
birds that they or their relatives had at some time seen or heard of but 
which I failed to collect (pp. 90-91). ‘These descriptions included even 
inconspicuous, undistinctive, and rare warblers, and species of which 
one individual had been caught 10 years ago but which had never been 


19 


FEATURES OF THE EASTERN HIGHLANDS 


seen since. Most of these descriptions are identifiable, and none re- 
sembles any of the drop-outs. The Fore and Daribi are unlikely to 
have overlooked birds with habits as distinctive as those of Orthonyx 
temmincku and Climacteris leucophaea while distinguishing sibling 
species in the warbler genera Sericornis and Crateroscelis. Thus, I con- 
sider it highly probable that most of the apparent drop-outs are 
actually missing in the Eastern Highlands. 

One must still ask whether the absences could be related to replace- 
ment by closely similar competing species or to the absence of suitable 
habitat. ‘The former explanation applies to a tenth species, Melidectes 
ochromelas, which is also absent in the Eastern Highlands while pres- 
ent to the east and west. As discussed (pp. 388-389), there is an unusual 
competitive situation involving three congeneric species in genus Melli- 
dectes, and the absence of M. ochromelas is correlated with the pres- 
ence of two of its congeners. Coracina lineata, Ptiloprora plumbea, 
and Melanocharis arfakiana are members of large genera, and com- 
petition may also play a role in their absence, though not in any 
simple fashion—i.e., their distributions are not complementary to the 
distribution of congeners, as in the Melidectes case. No such factors 
suggest themselves in the remaining cases. Elsewhere in New Guinea 
Lonchura monticola is the common and sole alpine grassland man- 
nikin; Macgregoria, a very distinct monotypic genus, is the common 
and sole bird of paradise above 11,000 ft; the creeper Climacteris 
leucophaea is the only representative of its family in New Guinea; 
Orthonyx temmincki has distinctive habits and no congeners in New 
Guinea; and the thrush Amalocichla sclateriana lives at altitudes above 
its only congener and overlaps altitudinally only one other thrush 
(Turdus poliocephalus), which has a quite different diet (mainly fruit 
instead of insects). In the Eastern Highlands the niches of these drop- 
outs remain unfilled in their absence. 

Thus, as illustrated in Map 4 (p. 19) for Climacteris leucophaea, the 
distribution of these drop-outs on the Central Range shows a gap of 
about 250 miles in the Eastern Highlands. For the alpine species 
Lonchura monticola and Macgregoria pulchra the available habitat 
is discontinuous, but for the remaining drop-outs the Central Range 
presents a 1,000-mile stretch of habitat with no major barriers. One is 
accustomed to encountering drop-outs in the avifaunas of isolated 
mountain ranges, but the finding of drop-outs in sections of a con- 
tinuous habitat may come initially as a surprise. However, the other 
parts of the Central Range also have drop-outs (pp. 46-47). South- 
eastern New Guinea “inexplicably” lacks five or six montane species 
that are present on the Central Range both in western New Guinea 
and in the Eastern Highlands. ‘These are Porzana tabuensis, Pachy- 
cephala tenebrosa, the Paradigalla superspecies, Lophorina (Pterido- 
phora) alberti, and Archboldia papuensis; the Melidectes nouhuysi-M. 
princeps superspecies is also missing but may be excluded by com-

peting congeners, as discussed on p. 391, Ihe western part of the 
Central Range also “inexplicably” lacks four montane species present 
both to the east on the Central Range and to the west on the Vogelkop, 
viz., Myzomela adolphinae, Erythrura papuana, Coracina lineata, and 
Melanoc haris arfakiana. These lists exclude species which are absent 
because their distribution complements that of a congener, or which 
appear to have split off recently from a close relative and to be in the 
process of expanding their range (cf., pp. 33-34). To set these numbers 
in perspective, New Guinea has about 170 widespread montane species 
or superspecies, so that the proportion of drop-outs in any given part 
of the Central Range is only 3-5%. The proportion of widespread 
species that drop out is much higher on the isolated mountain ranges 
of the Vogelkop and “north mountain islands”: Vogelkop, ca. 8%; 
Huon Peninsula, 8%; North Coastal Range, 58%; Cyclops Moun- 
tains, 77%; Adelbert Mountains, 82%. 

The drop-out phenomenon within New Guinea may be interpreted 
along the lines developed by MacArthur and Wilson (1967) for island 
faunas. To explain the fact that the number of species on an island 
is observed to increase with increasing island size and decreasing 
distance from the mainland, these authors postulated that the number 
of species in an island fauna represents an equilibrium between ex- 
tinction rates and immigration rates. Extinction rates are highest on 
the smallest islands, where populations consist of the fewest individuals 
and run the highest risk of being wiped out by random fluctuation in 
numbers due to transiently poor conditions, such as disease, accidents, 
failure in food supply, etc. Immigration rates increase with island size 
and proximity to the mainland. ‘he same principles find immediate 
application to the avifaunas of New Guinea’s isolated mountain ranges, 
which for montane birds represent distributional islands of suitable 
habitat in a “sea” of lowland. ‘These principles apply equally well to 
any portion of the continuous Central Range, and the only differ- 
ences from the situation on the isolated ranges are quantitative. A 
species is more likely to be eliminated by chance, and extinction rates 
are therefore higher, on a small mountain range with a small total 
population than on a large mountain mass such as the Eastern High- 
lands. When a species does disappear, immigration rates are higher on 
the Central Range, where recolonization occurs from immediately 
adjacent portions of the range, than on the isolated mountain ranges. 
Thus, the percentage of drop-outs is lowest on the various parts of 
the Central Range, higher on the large but isolated ranges of the 
Vogelkop and Huon Peninsula, and highest on the smallest isolated 
ranges (Cyclops Mountains and Adelbert Mountains). A similar phe- 
nomenon is encountered in the distribution of New Guinea lowland 
birds, because mountain ranges divide up the New Guinea lowlands 
into habitat islands of various sizes. For instance, the flat lowland 
strip hemmed in by mountains along the north coast of southeastern

FEATURES OF THE EASTERN HIGHLANDS 


New Guinea lacks several species, e.g., Pitohut kirhocephalus, Mino 
anais, Goura victoria, which are otherwise ubiquitous and common in 
the New Guinea lowlands. 

The drop-out phenomenon on the Central Range may provide one 
of the keys to how the New Guinea montane avifauna evolved. 
Speciation involves the breakup of what was originally one species 
into two geographically isolated daughter populations, which may 
diverge in isolation to the point where they are reproductively iso- 
lated and ecologically distinct when they come into contact again. One 
may therefore ask, “What provided the necessary isolation for specia- 
tions in the mountains of New Guinea?” A glance at a map of New 
Guinea (Map 1), with its continuous Central Range and isolated 
smaller ranges, might suggest that divergences took place between 
populations on the Central Range and populations on the isolated 
ranges, with the latter then reinvading the former to generate new 
species on the Central Range. If this were the case, one would expect 
to find distributional patterns reflecting early stages in the develop- 
ment of sympatry after reinvasion, such that one montane species 
occurrs on the Central Range and a different but closely related species 
occurrs on an isolated range plus the nearest portion of the Central 
Range. However, there is not a single such pattern involving any of 
the “north mountain islands,” and even the Vogelkop provides only 
a few possible examples, viz., Peneothello cryptoleucus and P. cyanus; 
Pachycephalopsis hattamensis and P. poliosoma; Ptiloprora erythro- 
pleura and P. perstriata. ‘This suggests that the isolates of the small 
detached ranges have rarely succeeded in reinvading the large Central 
Range. In contrast, there are numerous examples of pairs of forms that 
clearly represent every possible intermediate stage in speciation involv- 
ing eastern and western isolates on the Central Range. ‘These examples 
include: pairs of allopatric semispecies with one member in the 
western part and the other in the eastern part of the Central Range 
(e.g; Lophorina (Parotia) carolae and L. (Parotia) lawesi, Melidectes 
princeps and M. nouhuysi, Lophorina (Astrapia) splendissima and 
L. (Astrapia) mayeri and L. (Astrapia) stephaniae); pairs of closely 
related species that are sympatric over much of the middle of the 
Central Range but only one of which reaches the western tip and the 
other the eastern tip (e.g., Rallicula rubra and R. forbesi, Psittacella 
modesta and P. madaraszi, Epimachus fastosus and E. meyeri, Toxo- 
rhamphus novaeguineae and T. poliopterus); and pairs of closely re- 
lated species, one of which is confined to the eastern part of the Central 
Range and the other of which is distributed over the whole length of 
the Central Range (e.g., Pliloprora guise: and P. perstriata, Paradisaea 
rudolphi and the P. raggiana superspecies, Amblyornis subalaris and 
A. macgregoriae, and probably Cnemophilus macgregoriae and C. 
(Loria) loriae). 

These cases suggest that montane speciation in New Guinea can 


aa 


FEATURES OF THE EASTERN HIGHLANDS 


take place, and in most cases has taken place, on the Central Range 
alone, despite the absence of major east-west geographical barriers on 
this range. The apparent paradox of speciation on a continuous 
mountain range may be resolved by the drop-out phenomenon, which 
provides the necessary isolation. Evidently the first stage in speciation 
is the development of east-west clines and subspeciation on the Central 
Range, as illustrated by the subspecies of most midmontane birds 
(pp. 00-00). In the second stage an intermediate population dies out, 
as illustrated by the Eastern Highlands drop-outs. ‘These local ex- 
tinctions may have higher probabilities of occurring at times when the 
area of suitable habitat has been reduced by climatic or vegetational 
fluctuations, e.g., when a general cooling compresses forest altitudinal 
bands or when dry conditions restrict the forest. In the third stage 
the now-isolated eastern and western populations diverge to the point 
where they become well-marked subspecies or distinct members of a 
superspecies. ‘his stage is represented by the Alpine Mannikin, Lon- 
chura monticola, which occurs in southeastern New Guinea, has no 
population in the Eastern Highlands and is represented in western 
New Guinea by the semispecies, or very distinct subspecies L. montana 
(= L. monticola montana). ‘Vhe fourth stage is reached when these 
isolates come into contact again (e.g., the Parotia, Melidectes, and 
Astrapia superspecies cited above). In some cases the rejoined western 
and eastern populations will not have acquired reproductive isolation 
and will hybridize, leading to very distinct but interbreeding western 
and eastern subspecies (e.g., Crateroscelis robusta robusta and C. r. 
sanfordi, Rallicula forbesi forbesi and R. f. steint). In other cases, 
however, such as those cited in the previous paragraph, reproductive 
isolation will be perfected, and as the final stage in speciation the two 
forms will gradually reinvade each other’s ranges, or else one will re- 
invade the entire range of the other. ‘The ecological correlates of these 
east-west reinvasions follow a consistent pattern and are discussed on 
pp. 00-00. ‘These considerations may be relevant to speciation problems 
in continuous habitats in other parts of the world, such as the problems 
posed by the rich montane avifauna of the Andean chain of South 
America. 


Local “Drop-outs,” and Rare or Localized Species 


If in New Guinea one surveys the avifaunas of different mountains 
a few miles apart in the same range, one finds that a given mountain 
does not support the entire montane avifauna of the region but rather 
that some species are missing. Stein (1936) was struck by this point in 
comparing Mt. Kunupi and Mt. Sumuri, adjacent peaks in the Wey- 
land Mountains, and many examples turned up during my 1966 survey 
of four peaks in the North Coastal Range (Diamond, 1968). ‘The pat- 
tern of this effect is that the smaller the mountain, the more species 
are found to be missing at a given altitude. That is, a mountain 5,000 


23 


FEATURES OF THE EASTERN HIGHLANDS 


ft high obviously lacks all species restricted to elevations above 5,000 
ft, but it also lacks some of the species found at 3,000-5,000 ft on larger 
mountains. ‘he explanation is presumably the relation between species 
diversity and area: the smaller the mountain, the less the area at a 
given altitude, hence the fewer individuals in the local populations 
and the greater the likelihood of temporary local extinctions. In the 
Eastern Highlands this tendency is illustrated by Mt. Karimui, a peak 
8,400 ft high rising above the Karimui Basin (3,500 ft) and about 10 
miles from the nearest peak over 8,000 ft. We collected and netted 
many specimens on Mt. Karimui, and my field observations there for 
a month were supplemented by those of seven Fore assistants, three 
Gimi assistants, and five Daribi assistants who were intimately familiar 
with the New Guinea midmontane avifauna. Thus, our survey was 
probably complete, and most of the expected midmontane forest 
species including rare ones turned up. However, four species that are 
widespread elsewhere in the Eastern Highlands were not found and 
may be assumed to be absent on Mt. Karimui, viz., Ducula chalconota, 
Melampitta lugubris, Heteromyias albispecularis, and Melanocharis 
longicauda. 

A related phenomenon involves birds whose distribution is patchy 
to an extreme degree, such that well-established populations have 
been found at a few widely scattered localities but the species is 
absent in similar habitats over most of New Guinea. For instance, the 
Yellow-breasted Bird of Paradise, Loboparadisea sericea, was found 
to be fairly common at 3,000-6,000 ft at three far-flung localities (Mt. 
Kunupi at the western end of the Central Range, the Utakwa River 
in southwestern New Guinea, and Dawong in eastern New Guinea), 
and was otherwise known only from a few specimens at five other 
scattered localities until it turned up in numbers on the west ridge of 
Mt. Karimui. Archboldia papuensis sanfordi, a striking race of Arch- 
bold’s Bowerbird endemic to the Eastern Highlands, is known only 
from two very local populations, one on the southwestern side of Mt. 
Hagen and the other on Mt. Giluwe, despite extensive searches and 
inquiries among hundreds of natives by several ornithologists. ‘The 
Yellow Thicket Flycatcher, Poecilodryas placens, is present in six 
scattered areas and common in most of these (Batanta Island off the 
western end of New Guinea, the Menoo Valley of the Weyland Moun- 
tains, Astrolabe Bay in southeastern New Guinea, Lake Kutubu, and 
Karimui) but has been reported nowhere else. All three of these 
species have been missed in exhaustive collections involving thousands 
of specimens in numerous other areas. 

These and other rare or patchily distributed birds in New Guinea 
appear to fall into two categories. Some (c.g., Megatriorchis doriae, 
Rhamphomantis megarhynchus, Uroglaux dimorpha, Gampochaera 
sloetii, Androphobus viridis, Macgregoria pulchra, Loboparadisea 
sericea, Archboldia papuensis, and Daphoenositta miranda) belong to 


2A 


FEATURES OF THE EASTERN HIGHLANDS 


distinct monotypic genera without close relatives. Others (e.g., Ptilino- 
pus nanus, Charmosyna wilhelminae, Charmosyna multistriata, Tany- 
siptera nympha, Coracina lineata, Crateroscelis nigrorufa, Sericornis 
nigroviridis, Gerygone chloronota, Poecilodryas placens, Pachycephala 
aurea, Pachycephala tenebrosa, Meliphaga flavirictus, Ptiloprora plum- 
bea, Ptiloprora meekiana, Pycnopygius stictocephalus, and Melano- 
charis arfakiana) belong to large genera with many ecologically similar 
species. In many cases the habits of these local or rare species are 
sufficiently well known to rule out the suggestion that they have narrow 
ecological requirements uniquely met by only a few far-flung localities 
in New Guinea. Their fragmented, relict distributions suggest that 
more likely they are slowly becoming extinct, either because they are 
the last survivors of unsuccessful evolutionary lines (monotypic genera) 
or because they are being out-competed by ecologically similar close 
relatives in the same genus. 

Thus, a tendency to distributional patchiness expresses itself at 
several levels in the New Guinea avifauna: in differences between the 
avifaunas of nearby mountains; in large geographical gaps in the dis- 
tribution of otherwise widespread species; and in the highly frag- 
mented, relict-like distributions of other species. Examples of any of 
these phenomena may also be found in the temperate zones, but they 
are more prominent in New Guinea and perhaps in the tropics in 
general. The tendency to drop out or to be patchily distributed is as 
much a characteristic of a given species as its abundance, and is dis- 
tinct from abundance. For instance, the cuckoo Chrysococcyx meyerit, 
the thrush Drymodes superciliaris, and the honeyeater Meliphaga 
polygramma are always uncommon. Nevertheless, they turn up in low 
numbers at almost any hill forest collecting station on the Central 
Range and on most of the “north mountain islands” as well, on most 
of which some much commoner Central Range species (Pachycephala 
soror, the Melidectes honeyeaters) are absent. If one views local species 
diversity as an equilibrium between local extinction rates and immigra- 
tion rates, the greater patchiness of bird distribution in New Guinea 
as compared to the temperate zones is most readily explained by 
postulating lower dispersal rates in New Guinea. This postulate is 
almost certainly valid, since there is little migration in New Guinea 
forests and hence recolonization after local extinctions should be slow, 
whereas each year in the temperate zones the annual migrations and 
seasonal dispersals generate a flood of potential new colonists. Species 
vary in their dispersive tendencies and abilities, and these differences 
may partly underlie the tendency toward patchy distribution that is 
characteristic of certain species. An additional contributing factor may 
be the closer niche packing and increased interspecific competition 
resulting from higher species diversity in the tropics, such that the 
local survival of each species becomes more precarious (MacArthur, 
i972, ‘chapter 2). 


FEATURES OF THE EASTERN HIGHLANDS 


In short, the distributional patchiness of many New Guinea birds 
comes initially as a surprise to some temperate zone ornithologists, 
whose first reaction may be to dismiss the phenomenon with a trivial 
explanation such as that the patchiness is due to inadequate explora- 
tion or highly specialized habits. Enough is known about distribution 
in most cases, and about habits in many cases, to dismiss these explana- 
tions. In fact, distributional patchiness is seen on reflection to be an 
expected consequence of low dispersal rates and high species diversity 
in the New Guinea forest and of the continuing occurrence of specia- 
tion. In a saturated fauna an automatic corollary of the fact that new 
species are constantly arising is that other species must constantly be 
becoming extinct. The New Guinea avifauna provides clear examples 
of intermediate stages both in speciation and in extinction. 


ECOLOGICAL SORTING MECHANISMS 


If two formerly conspecific forms have succeeded in perfecting 
reproductive isolating mechanisms by the time contact is reestablished 
after a period of geographic isolation and evolutionary divergence, 
they then fulfill the definition of species. For the forms to succeed in 
reinvading each other’s ranges and to become sympatric, they must in 
addition develop ecological differences sufficient to permit coexistence. 
That the development of reproductive isolating mechanisms and of 
these ecological sorting mechanisms may proceed at different rates is 
shown by the existence of superspecies, comprised of forms which are 
perfectly, or nearly perfectly, isolated reproductively but which are 
strictly allopatric in distribution, presumably because ecological dif- 
ferences are still insufficient to permit reinvasion. Examples are: Chal- 
copsitta; Psittaculirostris; Micropsitta keiensis and M. pusio; Lalage; 
Parotia; Melipotes; the Melidectes ruforissalis group; and Melidectes 
nouhuysi and M. princeps. In addition to being a prerequisite for 
completion of the speciation process, ecological sorting mechanisms 
also underlie the problem of species diversity, viz., the question of 
what makes it possible for many species to coexist at a locality (Lack, 
a): 

Lack (1944) has analysed the avifauna of Great Britain, and Moreau 
(1948) the avifauna of Tanganyika, by determining the ecological sort- 
ing mechanisms between the members of all pairs of species in a given 
family. In the present analysis of ecological sorting mechanisms in the 
Eastern Highlands of New Guinea I shall adopt a narrower choice of 
material for analysis and shall largely confine discussion to pairs of 
congeneric rather than merely confamilial species. Confamilial species 
of different genera presumably have been distinct longer, and might 
be expected to have diverged ecologically from each other in more 
ways, than have congeneric species. One, in fact, finds that most 
congeneric pairs of species in New Guinea differ ecologically mainly 


26 


FEATURES OF THE EASTERN HIGHLANDS 


in one or two simple respects. These ecological sorting mechanisms 
may be classified under three headings: spatial differences (altitudinal 
segregation, habitat preference, vertical segregation, allopatry, and 
checkerboard allopatry) which lead to pairs of congeners having 
mutually exclusive territories; differences in feeding or foraging be- 
havior; and temporal differences (occupation of the same habitat at 
different times). ‘These categories will be considered in turn. 


1. Spatial Segregation 


Altitude——TVhe most important ecological sorting mechanism in the 
New Guinea avifauna as a whole, and in the Eastern Highlands in 
particular, is segregation by altitude. That is, more pairs of congeners 
segregate by living at different altitudes than by any other means. ‘The 
Eastern Highlands provide about 37 instances of pairs of similar and 
congeneric species which live in the same gross habitat type but have 
altitudinal ranges which are largely or completely mutually exclusive. 
Some examples (citing the low-altitude form first in each case) are the 
pigeons Ducula rufigaster and D. chalconota, the kingfishers Halcyon 
torotoro and H. megarhyncha, the flycatchers Peltops blaimvillii and 
P. montanus, the flycatchers Machaerirhynchus flaviventer and M. 
nigripectus, the bowerbirds Ailuroedus buccoides and A. crassirostris, 
and the honeyeaters Ptiloprora guisei and P. perstriata. In about 12 
additional cases there are three similar congeners which replace each 
other with altitude. Examples include the logrunners Eupetes caerules- 
cens, E. castanonotus, and E. leucostictus and the flowerpeckers Melan- 
ocharis nigra, M. longicauda, and M. verstert. Four congeneric species 
replace each other successively in two cases (the warbler genus Seri- 
cornis and the bird of paradise Lophorina), and in the whistler genus 
Pachycephala there is a sequence of five species. Many similar cases 
have been discovered by ‘Yerborgh (1971) in the avifauna of the Peru- 
vian Andes. 

In a considerable portion of these cases the altitudinal transition is 
sharp, mutual exclusion of each species from the other’s range is com- 
plete, there are no significant ecological differences between the species 
except for those associated with altitudinal range, and the species are 
quite similar to each other morphologically and apparently are the 
product of a recent speciation. One case (p. 230) is provided by the 
warblers Crateroscelis murina and C. robusta, which are the com- 
monest insectivorous gleaners of the understory, resemble each other 
in color, pattern, size, and song, and forage in virtually identical man- 
ners between ground level and five feet above the ground. As we 
ascended the west ridge of Mt. Karimui from its base, C. murina pro- 
gressively increased in abundance with increasing altitude until it was 
the second most abundant bird in Zone 3b (5,080 to 5,390 ft). It 
abruptly disappeared at 5,390 ft. At 5,400 ft C. robusta abruptly ap-

peared at its maximum abundance and progressively decreased in 
abundance with increasing altitude towards the summit at 8,165 ft 
(Fig. 1). No individual of either species was ever found within the 
other's altitudinal zone. There was no vegetational discontinuity in 
the forest at the transition altitude, and the ecotone at the lower level 
of the moss forest lay at 6,500 ft, which is 1,100 ft higher. As shown 
in Figure 2, which depicts the altitudinal ranges of the Crateroscelis 
warblers at various localities at different longitudes on the Central 
Range, the transition altitude varies locally between 4,500 and 5,500 ft, 
but there is no consistent difference between eastern and western New 
Guinea. Additional instances of similarly sharp transitions are discussed

and C. schisticeps, Rhipidura hy perythra and R. albolimbata, and the 
genera Eupetes, Sericornis, Peltops, and Ailuroedus). 

To varying degrees in other instances the altitudinal transition is 
not sharp, ecological sorting mechanisms in addition to altitudinal 
distribution are apparent, and the two or more species, while con- 
generic, show sufficient morphological differences to suggest that speci- 
ation occurred less recently. For instance, the pigeons Ptilinopus 
ornatus and P. perlatus have similar color patterns suggesting recent 
divergence, and in general represent each other altitudinally, P. perla- 
tus being found at lower elevations. However, P. perlatus is less com- 
mon, and the altitudinal ranges of the two species overlapped at 
Karimui, an overlap made possible by P. perlatus’s larger size and its 
preference for the forest edge over the forest interior. On the southern 
slopes of the Eastern Highlands live three congeneric parrots, Char- 
mosyna placentis occurring at low elevations, C. pulchella at medium 
elevations, and C. papou at higher elevations. ‘he altitudinal ranges 
are largely mutually exclusive, but each overlaps the next by up to 
several hundred feet. C. placentis is more closely related to other 
species in the genus than to C. pulchella or to C. papou; the latter two 
share the same distinctive color pattern with each other but differ by 
a factor of 2.6 in weight. The five whistlers Pachycephala griseiceps, 
P. hyperythra, P. soror, P. schlegelii, and P. modesta are encountered 
from sea level to timberline in that sequence, but their altitudinal

the other two species. None of the 10 expeditions on whose records the figure is

ranges overlap broadly: P. soror straddles the ranges of P. hyperythra 
and P. schlegelii, which nearly meet; the range of V. schlegeli: uciudes 
much or most of that of P. modesta; and that of P. griseiceps includes 
most or all of that of P. hyperythra. No two of these five species are 
as immediately derived from each other as are Crateroscelis murina 
and C. 10busta, or Ptiiinopus ornatus and P. periatus. The additional 
ecological sorung mechanism making altitudinal overlap possible is 
a tendency towards vertical segregation: on the average P. griseiceps 
forages higher in the vegetational column than does P. hyperythra, 
P. hyperythra higher than P. soror, P. soror perhaps higher than P. 
schlegelu, and P. schlegelii lower than P. modesta. ‘Vhe correlation 
between degree of morphological similarity and strictness of altitudi- 
nal segregation in bird altitudinal sequences in New Guinea suggests 
that strict altitudinal segregation was the first sorting mechanism to 
develop in these cases, and that some degree of altitudinal overlap 
became possible only as further evolution and morphological di- 
vergence led to other ecological differences. ‘his interpretation is 
supported by the evidence presented on pp. 33-34. 

Certain high-altitude species appear to take over the combined 
niches of several low-altitude congeners. For instance, in the cuckoo 
genus Cacomantis the single species found above 6,000 ft is C. pyr- 
rhophanus, which inhabits the forest interior as well as second-growth 
and gardens. Below this elevation it is replaced by two species, C. 
castaneiventris in the forest interior and C. variolosus in second- 
erowth and gardens. Up to six species of Piilinopus pigeons may be 
found locally sympatric at low elevations, differing in size and prefer- 
ence for the forest interior versus the forest edge. ‘These yield to one 
medium-sized species, P. rivoli, at higher elevations. 

I found that individuals collected outside a species’ usual alti- 
tudinal range and in the range of a congener generally proved to be 
immatures. A typical example arose on Mt. Karimui in the warbler 
genus Sericornis, four species of which divided up the mountain into 
mutually exclusive altitudinal bands; S. spilodera up to 4,240 ft, S. 
arfakianus from 4,400 to 5,000 ft, S. perspicillatus from 5,100 to 6,350 
ft, and S. papuensis from 6,450 ft to the summit at 8,165 ft. The only 
violation of these limits detected came when two immature individuals 
of S. spilodera were collected at 4,950 it, mean the wpper limit or thie 
next higher species. 

This tendency of immatures to be found at the peripheries of the 
altitudinal range characterizes most species of the New Guinea mon- 
tane avifauna, and not just those which belong to altitudinal se- 
quences. The change in population structure with increasing altitude 
is typically that immatures are found at the bottom of the altitudinal 
range; somewhat higher one meets immatures plus birds in adult plum- 
mage but in nonbreeding condition, with females usually appearing 
at lower altitudes than males; next comes the optimal part of the 


30 


FEATURES OF THE EASTERN HIGHLANDS 


species’ range, with singing males and adults of both sexes in breeding 
condition; and, finally, another band of immatures but of few adults 
appears at the upper altitudinal limit in some species. Examples of 
this population structure discussed in detail in the species accounts 
include Pachycephala leucostigma, Pachycephala schlegeli, Myzomela 
rosenbergii, Melipotes fumigatus, and Ptiloprora guiset. ‘Vhis tendency 
is manifest to an extreme degree in some species of birds of paradise, 
in which displaying adult males may be compressed into the top 600 
ft of the altitudinal range, with adult females and especially imma- 
tures continuing to be found several thousand feet below the level 
at which the lowest adult male is encountered (cf. Lophorina superba; 
Lophorina (Diphyllodes) magnifica; Lophorina (Cicinnurus) regia; 
and Loboparadisea sericea). Stein (1936) explicitly remarked on the 
same population structure for the birds of paradise Cnemophilus 
(Loria) loriae, Lophorina (Pteridophora) alberti, Epimachus fastosus, 
and Epimachus meyeri in the Weyland Mountains. 

Two explanations suggest themselves for the sharp transitions in 
sequences of altitudinally segregating congeners. On the one hand, the 
actual altitudinal limits of a species might be directly determined by 
its adaptations, either to altitude itself, or else, probably more im- 
portantly, to variables correlated with altitude, notably vegetation 
and temperature. On this hypothesis each member of an altitudinal 
sequence would be adapted only to a certain range of altitudes (or 
forest types or temperatures) and would be unable to maintain stable 
populations beyond its actual limits, even if the other species in the 
sequence were absent. By this interpretation the actual altitudinal 
limits and the physiologically possible altitudinal limits of a species 
would be identical, and would be sharp only if there were a sharp 
change in an adaptively critical environmental variable. ‘The alterna- 
tive hypothesis is that the actual altitudinal limits of a species depend 
upon competition with other species. Each species would be in- 
trinsically capable of establishing itself over a broader altitudinal 
range than that which it actually inhabits. However, in the presence 
of ecologically very similar species each form would be limited to 
that altitudinal range (or temperature range or vegetational type) 
over which it was competitively superior, and would be excluded from 
adjacent altitudinal bands in which the related species were competi- 
tively superior. 

While the first hypothesis (intrinsic survival ability) may prove valid 
in some instances, competition is clearly the explanation in many 
cases. To begin with, competition appears the only reasonable inter- 
pretation when the population density of one species changes from 
maximal to zero and the abundance of a closely related congener 
changes from zero to maximal within the same 10 vertical feet in a 
gradually changing forested habitat. Had sharp species transitions in 
altitudinal sequences been due to a sharp vegetational discontinuity 


31

rather than to competition, then the bird transitions should have co- 
incided with vegetational ecotones, and many bird transitions should 
have clustered around the same altitude. ‘These expectations are not 
fulfilled, as illustrated by Figure 3, which plots those transition alti- 
tudes between congeneric birds on Mt. Karimui’s west ridge that I 
was able to determine most accurately. ‘The sharpest ecotone was that 
at 6,500 ft at the lower limit of the heavily mossed zone. No bird 
transition coincided with this ecotone, and the nearest transition was 
the one about 100 vertical feet below between Sericornis papuensis

Fic. 3. Some altitudes on Mt. Karimui’s west ridge at which pairs of congeneric 
or closely related species replaced each other abruptly. In each case the first-named 
species is the low-altitude form, the last-named species the high-altitude form. A 
sharp line means that the transition altitude was identified exactly, while a bracket 
means that the transition occurred at some altitude within the indicated band bux

and S. perspicillatus. Figure 3 also shows that different bird transitions 
occur at different altitudes, and that at least one transition is en- 
countered every 600 feet in the well-studied region between 3,650 and 
8,165 ft. Few transitions were identified between 3,250 and 2,000 it, 
partly for the trivial reason that no collecting was carried out in this 
band, partly because in the Karimui area this altitudinal band consti- 
tutes part of a relatively well-defined ia ‘zone’ with few species 
limits (pp. 67-70). 

The facts that few or no vegetational ecotones in the New Guinea 
forest are as sharp as many bird transitions in altitudinal sequences, 
and that these sharp transitions do not coincide with ecotones, imply 
that sharp transitions involve competition. To test this hypothesis, 
one would like to find situations in which one member of a sequence 
has been locally eliminated, and to examine whether its congener, 
freed of the competition, expands into the missing species’ altitudinal 
range. This test is made possible by two different circumstances: the 
drop-out phenomenon and the reinvasion situation. 

As discussed on pp. 21-24, small mountains and mountain ranges 
have fewer bird species than large ones because localized populations 
are most likely to become extinct. Under these circumstances one often 
finds that congeners expand their altitudinal range at the expense of 
the missing species (Diamond, 1970a, 1970b). For instance, in the 
Okapa area the altitudinal ranges of the low-altitude flowerpecker 
Melanocharis nigra and its high-altitude congener M. versteri were 
separated by several thousand feet, and the intervening altitudes were 
monopolized by the middle-altitude congener M. longicauda. On iso- 
lated and small Mt. Karimui, M. longicauda was one of the species 
that dropped out, and M. nigra expanded upwards and M. versteri 
downwards to meet somewhere between 4,300 and 4,500 ft. In the 
North Coastal Range the cuckoo-shrike Coracina schisticeps occurred 
at most localities up to about 2,900 ft, above which altitude it was 
replaced by C. montana. However, on Mt. ‘Turu, an isolated peak only 
3,650 ft high, C. montana was absent, presumably because it could not 
maintain a stable population within a band of only 750 vertical feet; 
and C. schisticeps, freed of the competition, occurred up to Mt. ‘Turu’s 
summit. Similar instances arise among altitudinally representative 
species in Rallicula, Charmosyna, Psittacella, Crateroscelis, Pachyceph- 
ala, and Melidectes. 

The second kind of test for competition occurs during speciation, 
when one form begins to reinvade the geographical range of another 
to which it was formerly allopatric. As discussed on pp. 22-23, speci- 
ation in the New Guinea mountains usually begins with the formation 
of eastern and western isolates. There are 13 cases in which allied 
eastern and western species are sympatric only over part of the geo- 
graphical range, indicating that reinvasion is at an early stage. In 1] 
of these cases the two species have mutually exclusive altitudinal 


33 


FEATURES OF THE EASTERN HIGHLANDS 


ranges in the area of sympatry, and each has a broader altitudinal 
range outside the area of sympatry. For instance, the honeyeater 
Pile nnons guises occurs on the Central Range in eastern New Guinea 
and on one “north mountain island,’ the Huon Peninsula. The sim- 
ilar P. perstriata occurs on the Central Range in both western and 
eastern New Guinea. In western New Guinea, where P. perstriata oc- 
curs alone, it lives from about 5,000 to 12,000 ft. In the area of sym- 
patry, eastern New Guinea, P. perstriata lives from about 9,000 to 
12,000 ft, P. guisei from 5,000 to 9,000 ft, and the altitudinal ranges 
are mutually exclusive. On the Huon Peninsula, where P. guise occurs 
alone, it lives from 5,000 to apparently at least 10,500 ft. Thus, in the 
area of sympatry the altitudinal ranges of both species are apparently 
compressed by competition as compared to the range each can inhabit 
when by itself. A clear example of the development of an ecological 
sorting mechanism in the earliest stage of speciation is presented by 
the birds of paradise Lophorina (Astrapia) mayert and L. (Astrapia) 
stephaniae, between which reproductive isolation is not yet complete 
and whose ranges are still largely allopatric. Sympatry has been re- 
ported only from two mountains, Mts. Giluwe and Hagen, where the 
two forms segregate altitudinally, L. (Astrapia) mayert being found at 
higher elevations. Similar instances in the Eastern Highlands arise in 
the bird of paradise genus Epimachus, in the honeyeater genus Tox- 
orhamphus, and apparently in the megapode genus Talegalla. 

Thus, the principal (but not the only) speciation mechanism in 
the mountains of New Guinea appears to be the formation of western 
and eastern isolates, followed by mutual reinvasion with altitudinal 
displacement, until the two species occur sympatrically over all New 
Guinea with mutually exclusive altitudinal ranges. In most cases alti- 
tudinal segregation is the first ecological sorting mechanism to develop, 
and other differences develop only later, after broad sympatry has 
been achieved (cf. pp. 29-30). 

In some genera this process has occurred two or three successive 
times to give rise to three-species and four-species altitudinal  se- 
quences. However, two-species sequences are much commoner in New 
Guinea. The larger sequences tend to be unstable and to lead to 
elimination of the middle birds, whose narrow altitudinal ranges due 
to competition from both above and below make them particularly 
prone to drop out locally. The narrowest altitudinal ranges in the 
New Guinea mountains prove to be those of middle birds in three- 
and four-species sequences. For instance, on Mt. Karimui the warbler 
Sericornis arfakianus, the second bird in a four-species sequence, was 
compressed into a band of only 600 feet, while Melanocharis longi- 
cauda, middle bird in a three-species sequence, was missing entirely, 
having been squeezed out between its congeners. In the Cyclops Moun- 
tains and North Coastal Range the whistler Pachycephala soror, third 


34 


FEATURES OF THE EASTERN HIGHLANDS 


in a five-species sequence, has similarly been squeezed out between 
P. hyperythra and P. schlegeli. ‘The warbler Crateroscelis nigrorufa, 
middle bird in a three-species sequence, is very rare and local, presum- 
ably because it has been eliminated at most localities. ‘The instability 
of three-species sequences also appears responsible for the unique and 
complex distributional pattern of compound checkerboard allopatry 
in the Melidectes rufocrissalis-M. belfordi-M. ochromelas complex (pp. 
388-389; 393-396). 

To recapitulate, sharp altitudinal transitions between congeners are 
due to competition, as shown by the facts that most vegetational eco- 
tones are much less sharp; that the transitions do not coincide with 
ecotones or with each other; that the component species expand their 
ranges when one member drops out locally; and that they compress 
their ranges in the zone of sympatry during reinvasion. In the Andes 
of Peru ‘Terborgh (1971) has described essentially identical phenomena 
exemplified by numerous altitudinal sequences of two to five species. 
It is worth restating explicitly that the bearing of adaptations to alt- 
tude, vegetation, and temperature on the sequences is not denied. ‘The 
fact that Crateroscelis murina lives below C. robusta, and not vice 
versa, can only mean that the former is better adapted to low altitude, 
rainforest, and warm temperatures and that the latter is better adapted 
to high altitude, Nothofagus forest, and cool temperatures. It is the 
sharpness of the transitions, and the mutually exclusive altitudinal 
ranges, in the absence of equally sharp changes in temperature and 
forest composition, which must be explained in terms of competition. 

Habitat—Congeners that live at the same altitude may differ in 
respect to the gross habitat type preferred (forest, second-growth and 
forest edge, grassland, savanna, swamp, or water). Since the fractional 
area occupied by gross habitat types other than forest is small in un- 
disturbed areas in most parts of New Guinea (especially in the moun- 
tains) except in a low-rainfall band on the south coast, the proportion 
the nonforest avifauna bears to the total avifauna in New Guinea is 
low. ‘The nonforest avifauna of the Eastern Highlands is discussed 
on pp. 70-79. 

In the following 18 pairs or groups of species which occur in the 
Eastern Highlands, the first member lives mainly at the forest edge, in 
second-growth, or in gardens, while the second member or members 
live mainly in the forest, but the birds are otherwise fairly similar 
ecologically. Details are given under individual species accounts:

The rail Rallus pectoralis occurs in dry grassland, while the similar

In the hills the swiftlet Collocalia esculenta is confined to the air 
space above small streams and forest glades, while C. hirundinacea 
forages over extensively cleared areas. 

Vertical distribution.—Many New Guinea forest species show strict 
preferences for the height in the vegetational column at which they 
forage. For example, the warblers Crateroscelis robusta and C. murina 
are almost always seen within five feet of the ground, the thicket fly- 
catcher Pachycephalopsis poliosoma within three feet of the ground, 
and the logrunners Eupetes castanonotus and E. lewcostictus remain 
on the ground or on fallen branches. Conversely, the warbler Gerygone 
palpebrosa and the flycatcher Monarcha frater often forage down to 
within about 12 ft of the ground but never within five feet of the 
ground. These vertical preferences are well illustrated by results of 
mistnetting, since our mistnets generally extended from near the 
ground to six feet above the ground. Despite intensive use of mistnets 
(about 30 in operation simultaneously) many common forest species 
were never netted, and some species (e.g., the thicket flycatcher 
Pencothello cyanus and the honeyeater Toxorhamphus poliopterus) 
were netted much more often in proportion to their censused abundance 
than others. I shall frequently cite netting results in the individual 
species accounts as an indication of vertical foraging preference. While 
temperate zone species, of course, also have vertical preferences, these 
are less strict and absolute than in species-rich areas of the tropics. 
For instance, if one operates mistnets for a long time, one eventually 
catches every species of bird present in New Zealand forest or in east- 


36 


FEATURES OF THE EASTERN HIGHLANDS 


ern North American forest, but litthe more than half of the species 
present in New Guinea (in my experience) or in Peru (Terborgh, pers. 
comm. ). 

The following 19 forest species in the Eastern Highlands apparently 
forage strictly or almost strictly on the ground: the cassowaries Casu- 
arius bennettii and C. casuarius, the megapodes Megapodius freycinet, 
Talegalla sp., and Aepypodius arfakianus, the rail Rallicula forbesi, 
the woodcock Scolopax saturata, the ground doves Gallicolumba bec- 
carii, G. rufigula, G. jobiensis, and Chalcophaps stephani, the pittas 
Pitta erythrogaster and P. sordida, the thrushes Zoothera dauma, Am- 
alocichla incerta, and Drymodes superciliaris, and the logrunners Eu- 
petes castanonotus, E. leucostictus, and Melampitta lugubris. 

Three additional forest species apparently forage on the ground 
and in undergrowth within a few feet of the ground: the thicket fly- 
catchers Heteromyias albispecularis and Pachycephalopsis poliosoma, 
and the whistler Pitohwi cristatus. 

Eight species forage in the understory within five feet, or in a few 
cases ten feet, of the ground but usually not on the ground itself: the 
warblers Crateroscelis murina, C. nigrorufa, and C. robusta, the fly- 
catcher Rhipidura threnothorax, and the thicket flycatchers Pene- 
othello sigillatus, P. cyanus, P. bimaculatus, and Poecilodryas placens. 

At the other extreme are the numerous forest species which keep to 
the middle and upper stories and rarely descend to the lower story. ‘To 
quantitate this phenomenon by mistnet results, let us exclude from 
consideration birds weighing over 250 g (hence possibly strong enough 
to break out of the mistnets I was using, although a few larger birds 
were in fact netted), and consider only species of which I saw, heard, 
or collected at least 10 individuals. ‘Vhis leaves 137 forest species. Of 
these 137 species, 77 (569%) were netted at least once, while 60 (44%) 
were never netted. ‘The list of 60 species not netted includes most 
pigeons except for the four small ground doves of the genera Galli- 
columba and Chalcophaps; most parrots except Psittacella; the cuckoo 
Eudynamis scolopacea; all campephagids without exception; the war- 
blers Phylloscopus trivirgatus and Gerygone ruficollis; the flycatchers 
Peltops montanus and P. blainvillit, and Monarcha frater and M. 
chrysomela; the whistler Pachycephala hyperythra; the oriole Oriolus 
szalayt; the birds of paradise Manucodia (including “Phonygammus’’), 
Epimachus (including “Drepanornis’), Paradisaea, and Loboparadisea, 
and Lophorina (Parotia) lawesi (despite the male’s terrestrial display 
court) and Lophorina (Ptiloris) magnifica; the honeyeaters Myzomela 
eques, M. nigrita, M. cruentata, Oedistoma pygmaeum, Meliphaga 
subfrenata and M. analoga, and Pycnopygius ixoides; and the dicaeids 
Dicaeum geelvinkianum and Oreocharis arfaki. In addition, I netted 
females but never males of the honeyeater Meliphaga obscura, al- 
though males were collected by other means. There are a couple of 
these species that I netted elsewhere in New Guinea or observed in the 


37 


FEATURES OF THE EASTERN HIGHLANDS 


understory despite my failure to net them. Most of them, however, are 
species that I saw dozens or hundreds of times and which simply do 
not descend to the understory, unless under the unusual conditions 
noted below. 

Of the 77 species netted, seven rarely use the understory and were 
netted only under one of three unusual conditions. First, birds flying 
from one side of a ridge to another often prefer to fly through a notch 
or dip in the ridge, and if one sets up nets in such a notch, anything 
may turn up. For instance, one such net on Mt. Menawa in the North 
Coastal Range caught a flock of 25 Charmosyna parrots, which feed in 
the crowns of flowering trees. Secondly, at high elevations where the 
fovest becomes stunted, species that remain in the middle- and upper- 
stories of tall forest turn up in nets, simply because the middle- and 
upperstories disappear at high elevations. For instance, the parrot 
Oreopsittacus arfaki and the honeyeater Myzomela rosenbergii were 
netted in the stunted summit forests of Mt. Michael and Mt. Karimui 
but not in the taller forest at lower elevations. Finally, some species 
present both in the forest interior and at the edge are netted much less 
often in the interior than at the edge (e.g., the honeyeaters Melipotes 
fumigatus, Melidectes rufocrissalis, and Meliphaga orientalis). 

‘Thus, almost half of the forest species in the Eastern Highlands have 
sufficiently marked middle- and upperstory preferences that they are 
rarely or never netted in the forest. 

‘There are about eight pairs or groups of congeneric forest species in 
the Eastern Highlands for which differences in vertical preference pro- 
vide an important or the most important ecological sorting mechanism, 
one species foraging largely in the lower story and the other largely in 
the middle- and upperstories. All eight cases involve small passerines. 
In four of these cases the upperstory species was never taken in mist- 
nets, but even in these four instances the vertical segregation was not 
absolute because the lowerstory species was occasionally or often seen 
in the middlestory. The eight cases, listing the lowerstory bird or birds 
first in each case, are:

Allopatry—New Guinea provides numerous examples of super- 
species, i.e., pairs or groups of forms that already are, or may be 
assumed to be, reproductively isolated but whose distributions are still 
largely or strictly allopatric. Superspecies consist of isolates (‘“semi- 


38 


FEATURES OF THE EASTERN HIGHLANDS 


species”) between which geographical contact may have been reestab- 
lished but which are presumably still too similar ecologically to 
reinvade each other’s ranges. The Eastern Highlands contain about 
eight pairs of allopatric semispecies, which fall into two categories. 

The first category consists of lowland or hill forest species to which 
the Central Range, running east-west, presents a major barrier, so 
that one form has been isolated on the northern slopes of the Central 
Range and the other on the southern slopes. Four examples, listing 
the northern form first and the southern form second in each case, are 
the crowned pigeons Goura victoria and G. scheepmakeri; the fig par- 
rots Psittaculirostris edwardsti and P. desmarestti; the trillers Lalage 
atrovirens and L. leucomela; and the red birds of paradise Paradisaea 
minor and P. raggiana. In one additional case, the cassowary Casu- 
arius casuarius, one member of a superspecies has been found on the 
southern slopes, while the corresponding form of the northern slopes 
(Casuarius unappendiculatus) has not yet been reported from the 
Eastern Highlands but will undoubtedly turn up when the northern 
slopes are explored at low altitudes. 

The other category consists of midmontane species for which the 
Central Range does not provide a distributional barrier but which 
have formed eastern and western semispecies by the mechanism dis- 
cussed on pp. 22-23. In this category fall two pairs of birds of paradise, 
Lophorina (Astrapia) mayerit and L. (Astrapia) stephaniae, and Lo- 
phorina (Parotia) carolae and L. (Parotia) lawesi (the western form 
is listed first in each case). ‘he astrapias provide a fascinating example 
of the development of ecological sorting mechanisms in the early stages 
of reinvasion, and are discussed further on p. 34 and pp. 338-339. 

Finally, the megapodes Talegalla jobiensis and T. fuscirostris pro- 
vide at first glance another pair of northern and southern semispecies 
which are still allopatric, but the evidence discussed on p. 000 suggests 
that the development of sympatry and ecological sorting may actually 
be far advanced in this instance. 

Checkerboard allopatry—In the previously cited examples of al- 
lopatry, each member of the superspecies has a coherent and exclusive 
range, and a continuous geographical line running north-south or east- 
west divides it from its relative. here are in addition five puzzling 
cases of forms whose distributions appear to be largely or wholly 
allopatric but which replace each other in checkerboard fashion. ‘Thus, 
the range of each species is broken into discrete geographical areas 
separated from each other by areas inhabited by the other species. 
‘Three of these cases involve pairs of forms: the fruit doves Ptilinopus 
pulchellus and P. coronulatus, the owlet-nightjars Aegotheles albertisii 
and A. archboldi, and the mannikins Erythrura trichroa and E. papu- 
ana. A fourth case (pp. 388-389) consists of three honeyeaters (Meli- 
dectes rufocrissalis, M. belfordi, and M. ochromelas) and is more 
complex: most New Guinea mountains support two of these three 


39 


FEATURES OF THE EASTERN HIGHLANDS 


species, and the identity of the locally missing species varies geo- 
graphically in checkerboard fashion. The last case involves eight man- 
nikins of the genus Lonchura, which have colonized the midmontane 
erasslands in an irregular checkerboard, each area usually supporting 
only one species but the same species recurring in widely separated 
areas. Further details of all these cases are given under the individual 
species accounts. At least three different phenomena (habitat differ- 
ences, colonization, and recent range expansion) appear to be involved, 
as discussed in the following paragraphs. 

The geographical ranges of the fruit doves Ptilinopus pulchellus 
and P. coronulatus (pp. 124-125) both include essentially the whole of 
New Guinea. In some cases they replace each other over large areas. 
For instance, P. coronulatus is apparently found over the whole lower 
and middle Fly Rivers, while P. pulchellus is found on the upper Fly 
River; and P. coronulatus is on the northern slopes of the Eastern 
Highlands, P. pulchellus on the southern slopes. However, there are 
also areas, as on the Vogelkop, where these species replace each other 
over much shorter distances and inhabit smaller patches. One suspects 
that these two species recognize some consistent difference in the en- 
vironment or habitat and that a competitive equilibrium has been 
reached, each species being able indefinitely to exclude the other from 
the type of habitat in which it is competitively superior. However, the 
basis of this postulated habitat difference is unknown, and I cannot 
detect any feature which consistently characterizes the areas chosen by 
P. pulchellus and distinguishes them from the areas chosen by P. 
coronulatus. 

‘The checkerboard colonization of the midmontane grasslands by the 
eight Lonchura mannikins appears to have been settled on a “‘first 
come first serve” basis, and the diversity of habitats colonized by each 
species makes it unlikely that superior adaptations to subtle habitat 
differences determined the local winner. For instance, L. spectabilis 
is the sole mannikin for a distance of at least 150 miles in the mid- 
montane grassland of the Eastern Highlands over a considerable range 
of altitudes, climatic conditions, and grass types and heights; L. cani- 
ceps is equally well entrenched in midmontane grassland of south- 
eastern New Guinea presenting a similar but equally varied range of 
conditions; and L. tristissima fills this niche on several of the “north 
mountain islands” (see pp. 409-410 for details). The midmontane grass- 
lands in their present form are recent by-products of native agricul- 
ture, and much of their grassland avifauna consists of colonists from 
the lowlands. The Lonchura mannikins appear to colonize only with 
difficulty, so that for them the colonization of these grassland islands 
is a slow and random process. Once a given species arrives, it becomes 
established over the whole area and excludes potential future colonists. 
The identity of the locally successful colonist is usually as unpredict-

FEATURES OF THE EASTERN HIGHLANDS 


able as trying to guess which of several related species will become 
established on a particular oceanic island or on a particular mountain. 

The remaining three cases appear to involve recent range expan- 
sions due to invasions or speciations. In the genus Erythrura the 
species E. papuana is endemic to New Guinea, where it is known 
only from a handful of scattered localities. The very similar E. trichroa 
occurs from Celebes to Australia, the Solomon Islands, and Micronesia, 
and has been found at most midmontane localities in IwWew Guinea 
except those where E. papuana occurs (p. 000). Presumably £. papwana 
is the older species in New Guinea and has been eliminated at all but 
a few localities by E. trichroa, a recent invader from the outside. The 
other two cases (Aegotheles and Melidectes) suggest recent speciations 
within New Guinea itself. Aegotheles archboldi and A. albertisi re- 
place each other in checkerboard fashion in western New Guinea, 
while A. albertisii has the Vogelkop and eastern New Guinea to itself 
(p. 177). Sympatry has been demonstrated at one locality and may de- 
pend on different altitudinal preferences. Sympatry between those two 
of the three Melidectes forms present at a given locality depends also 
upon altitudinal exclusion. Apparently two successive speciations pro- 
duced three honeyeaters, and since altitudinal sequences of three spe- 
cies tend to be unstable in New Guinea (p. 34), one of the three species 
(but not always the same one) disappeared at each locality. 

Thus, the Erythrura case suggests a speciation and on-going rein- 
vasion during which an ecological sorting mechanism adequate to 
permit sympatry has not developed and the older form has been re- 
duced to a fragmented and possibly shrinking range. In the Aegotheles 
and Melidectes instances a sorting mechanism, viz., altitudinal segre- 
gation, has developed in at least a few areas, but either has failed to 
develop in most areas, or else was inadequate to guarantee stable sym- 
patric populations of both forms and resulted in local elimination 
of one. 


2. Nonspatial Sorting Mechanisms (Food and Foraging 
Differences) 

‘The sorting mechanisms discussed so far (altitude, habitat, vertical 
distribution, allopatry, and checkerboard allopatry) have as their usual 
result that the spatial overlap between territories of congeners is 
minimal or nonexistent. We shall now consider those factors, mainly 
related to food consumed and the means of obtaining it, that permit 
congeneric species to occupy spatially overlapping territories. It should 
at once be mentioned that it requires careful observation to decide in 
some cases whether segregation is mainly spatial or nonspatial. For 
instance, even when two congeners occur at the same locality, at the 
same altitude, and in the same gross habitat type and forage at the 
same height, they may still be interspecifically territorial due to their 


4] 


FEATURES OF THE EASTERN HIGHLANDS 


recognizing finer habitat categories, such as denser and less dense 
forest. ‘This is likely to prove true, for example, of the two ground 
doves Gallicolumba jobiensis and G. rufigula. Conversely, in the East- 
ern Highlands those congeners which have markedly different vertical 
foraging preferences appear in no case to have foraging spheres which 
completely exclude each other vertically, and other factors also con- 
tribute to niche differences. For instance, the honeyeater Meliphaga 
aruensis spends more time in the lowerstory than does M. analoga but 
also has a stouter bill; and the warbler Sericornis nouwhuysi spends 
more time in the lowerstory than do its congeners but is also a larger 
bird. 

The commonest type of nonspatial segregation among congeners in 
the Eastern Highlands depends upon a difference in body size, imply- 
ing an average difference in size of food taken or in places food is 
sought (a large bird can take larger food, but a light bird can forage 
on smaller twigs and perches). ‘There are 15 genera containing two or 
more species that overlap broadly in habitat and altitudinal prefer- 
ence but differ in size. The prize instance of segregation by size in 
New Guinea is provided by the pigeon genus Ptilinopus, which is rep- 
resented on the New Guinea mainland by 11 species, all of them fruit 
eaters, arboreal, and colored largely green. ‘The five that occur sym- 
patrically at Karimui form a graded size series, each about 1.5 times 
heavier than the next: P. nanus (average weight 49 ¢), P. pulchellus 
(76 g), P. superbus (123 g), P. ornatus (163 g), and P. perlatus (245 g). 
A sequence of three arises in the hawk genus Accipiter at Karimui; 
A. poliocephalus < A. novahollandiae < A. buergersi. Vhe other cases 
are listed in ‘Table 1. 

It will be seen from Table 1 that the weight ratio averages 1.9 and 
always falls between 1.33 and 2.73, usually between 1.5 and 2.5. ‘he 
fact that the values show only this limited spread about the optimal 
ratio is due to a balance of selective pressures. Birds with a lower 
weight ratio would be too similar to coexist and would have to segre- 
gate by some other means (altitude, habitat, allopatry, etc). Birds with 
a higher weight ratio would leave an intermediate niche empty: 1.e., a 
medium-sized bird could evolve or invade and not be too close in size 
to either the heavier or the lighter bird. For instance, if there were 
two otherwise similar birds with relative weights of 3.0 and 1.0, both 
could also coexist with a medium-sized bird whose relative weight 
was 30S ive 

Several pairs of congeners differ in other simple and obvious re- 
spects related to obtaining food. ‘The whistler Pachycephala leuco- 
stigma eats mainly fruit, while its congeners are largely insectivorous. 
The various species of honeyeaters of the Meliphaga analoga complex 
differ in the extent to which they use flowering trees. 

There remain several groups of congeners that share largely or in 
part the same gross habitat and are of similar sizes but between which

the ecological sorting mechanisms cannot be adequately defined at 
present. Presumably foraging differences remain to be identified i 
most of these cases, while interspecific territoriality based on fine 
habitat distinctions may be operative in a few: the hawks Accipiter 
novachollandiae and A. fasciatus, the pigeons Ducula zoeae and D. 
rufigaster, the ground doves Gallicolumba jobiensis and G. rufigula, 
the cuckoo-shrikes Coracina boyeri, C. melaena, C. schisticeps, and C. 
morio, the whistlers Pitohui kirhocephalus, P. dichrous, and: i. yer- 
rugineus, the honeyeaters Melidectes fuscus and M. princeps, and the 
flowerpeckers Melanocharis striativentris and M. longicauda or M. 
verstert. 
3. ‘Temporal Segregation 

In principle, two species could forage in similar manners in the 
same habitat if they occupied the habitat at different times of the year 
(or, conceivably, of the day). In practice, there are few cases suggestive 
of temporal segregation among New Guinea birds, since seasonal 
variation is so limited. The pigeon Ptilinopus superbus was breeding 
in the Eastern Highlands at a time when its congeners were not breed- 
ing. In the south coastal savanna at Merauke, where seasonal changes 
may be more marked than in rainforest, the harrier Circus spilonotus 
is present in the wet season, Circus approximans in the dry season 
(Hoogerwerf, 1964). The postulated local migrations of some montane 
lories (p. 80), if they really do take place, may result in temporal re- 
placement. The kingfisher Melidora macrorhina is partly or mainly 
nocturnal, whereas other kingfishers are diurnal. It would be worth 
noting whether those few New Guinea forest species (e.g., Halcyon 
megarhyncha, Eurystomus orientalis waigiouensis) which are conge- 
neric or conspecific with an Australian form wintering in open habi- 


tats in New Guinea spend more time in open habitats after the 
migrants leave. 


Some General Features of Ecological Sorting Mechanisms 

Two general remarks are appropriate at this point. 

‘There are systematic changes with altitude in the fineness of niche 
differences and in the relative importance of differing sorting mecha- 
nisms. Species cliversity decreases with increasing altitude, and niche 
differences become correspondingly coarser. At altitudes above 8,500 
ft, even in tall Nothofagus forest, most species in the impoverished 
avifauna belong to different genera or even families; no genus is rep- 
resented by three species living at the same altitude; and only seven 
genera (Psittacella, Aegotheles, Collocalia, Sericornis, Rhipidura, 
Pachycephala, Melidectes) are represented by two species at the same 
altitude. In contrast, below 3,000 ft there are nine genera in which 
one may find between four and eight congeners occurring sympatri- 
cally at the same altitude. While altitude provides the most important 


45 


FEATURES OF THE EASTERN HIGHLANDS 


sorting mechanism for the New Guinea avifauna taken as a whole, it 
is Obviously of no importance in the avifauna of the flat lowlands, 
where there are no differences in altitude. A different picture of the 
relative importance of various sorting mechanisms might also be ob- 
tained if one compared all species pairs in the same family, as Lack 
(1944) did for England and as Moreau (1948) did for Tanganyika, 
rather than just pairs in the same genus, as done here for the Eastern 
Highlands. 

The discussion of strict altitudinal segregation applies only to large 
areas of extensive virgin forest undisturbed by man, where ecological 
interrelationships are characterized by a beauty and simplicity lost in 
disturbed areas. Near human settlement one will look in vain for con- 
geners replacing each other within 10 vertical feet. For instance, the 
whistlers Pitohui nigrescens and P. dichrous had mutually exclusive 
altitudinal ranges on Mt. Karimui but were netted at the same altitude 
at the forest edge behind Awande. Vertical stratification also breaks 
down in ecologically disturbed areas. For instance, the honeyeater 
Meliphaga orientalis remains in the middle- and upperstories in un- 
disturbed forest and was never caught in mistnets on Mt. Karimui 
but was netted twice at Awande. Finally, even reproductive isolating 
mechanisms may break down in disturbed areas, as has occurred on 
a large scale in the case of the honeyeaters Melidectes belfordi and 
M. rufocrissalis. 


ZOOGEOGRAPHICAL AFFINITIES OF THE EASTERN 
HIGHLANDS AVIFAUNA 


The affinities of the Eastern Highlands nongrassland avifauna will 
be discussed, first at the species level, then at the subspecies level. ‘Uhis 
section extends a previous analysis by Mayr and Gilliard (1954, pp. 
328-329), which was based on Gilliard’s collections in the Wahgi 
region. 

As already mentioned, the Central Range provides an uninterrupted 
expanse of montane habitat with no known major east-west barriers 
between about longitudes 135°E and 150°E. Most montane species are 
distributed over the whole extent of the Central Range. Within the 
Central Range three lesser subdivisions may be recognized, most un- 
equivocally on the basis of species ranges (presence of a few endemic 
species, absence of a few widespread species) but also on the basis of 
subspecies: 

1. Southeastern New Guinea, extending from long. 150°E west to 
the Herzog Mountains (long. 146°30’E). ‘This region is characterized 
by six drop-outs, i.e., by the absence of six widespread species (Porzana 
tabuensis, Pachycephala tenebrosa, the Paradigalla superspecies, Lo- 
phorina (Pteridophora) alberti, Archboldia papuensis, and the Meli- 
dectes nouhuysi-M. princeps superspecies); by the absence of 


46 


FEATURES OF THE EASTERN HIGHLANDS 


Epimachus fastosus, a western product of a recent speciation that has 
yet to reach the southeast; by the presence of an endemic species, 
Amblyornis subalaris, the product of a recent speciation; and by the 
presence of five other species or semispecies resulting from recent 
speciations, shared with the Eastern Highlands and discussed 1m the 
next paragraph. 

2. Eastern Highlands, extending east at least to the Okapa area 
(long. 145°30’E) and west at least to Tari (long. 143°E) and probably 
at least to long. 142°30’E. This region is characterized by the absence 
of the nine drop-outs listed on pp. 00-00, and by the absence 
of Melidectes ochromelas, which is kept out by competitive exclusion 
(pp. 388-389); by the presence of two endemic semispecies, Lophorina 
(Astrapia) mayeri and Melidectes princeps; by the presence of two 
endemic semispecies shared with southeastern New Guinea, Lophorina 
(Parotia) lawesi and Lophorina (Astrapia) stephaniae; and by the pres- 
ense of three endemic species shared with southeastern New Guinea, 
all products of recent speciation (Cnemophilus macgregori, Para- 
disaea rudolphi, and Ptiloprora guiset). 

3. Western New Guinea, extending from long. 135°E east at least 
to the Telefolmin region (long. 141°30’E). ‘This region contains the 
highest mountains of New Guinea and has the most distinctive and 
numerous endemic species. here are three endemic species in mono- 
typic genera, two of them alpine birds: Anurophasis monorthonyx 
(alpine), Androphobus viridis, and Oreornis chrysogenys (alpine). 
‘There are four other endemic species, Aegotheles archboldi, Petroica 
archboldi (alpine), Pachycephala lorentzi, and Lonchura teerinki, and 
two endemic semispecies, Lophorina (Astrapia) splendissima and Meli- 
dectes nouhwysi. Seven other species, five of them apparently products 
of recent speciation, are shared with the Vogelkop but are absent from 
the Eastern Highlands and southeastern New Guinea: Rallicula rubra, 
Charmosyna josefinae, Melampitta gigantea, Peneothello cryptoleu- 
cus, Pachycephalopsis hattamensis, Ptiloprora erythropleura, and Zos- 
terops fuscicapilla, There are five drop-outs present on the Vogelkop 
and in eastern New Guinea but not on the western part of the Central 
Range (Coracina lineata, Myzomela adolphinae, Melanocharis arfaki- 
ana, Erythrura papuana, and Zosterops novaeguineae; the absence of 
the last-named species may be correlated with the presence of Zosterops 
fuscicapilla). Accipiter buergersi should perhaps also be considered a 
drop-out, since it occurs in southeastern New Guinea, the Eastern 
Highlands, and the Huon Peninsula but not in western New Guinea, 
has no close relatives, and must be a relatively old species. 

No systematic collecting has been done between long. 141°30’E and 
long. 143°E, or between long. 145°30’E and long 146°30’E. It remains 
to be seen how sharp these transition zones are, i.e., whether a region’s 
endemic species will disappear and its drop-outs reappear within a 


47 


FEATURES OF THE EASTERN HIGHLANDS 


short distance in these uncollected gaps. ‘These two transition areas 
are apparently less than 70-100 miles in extent, while the three regions 
are 200-440 miles in extent. 

The Eastern Highlands appear to be a fairly uniform region with 
respect to species and subspecies distributions above 5,000 ft. The 
exceptions to this statement are sufficiently few to be worth detailing. 
The only well-established limit of a midmontane species within the 
Eastern Highlands is that of the semispecies Lophorina (Astrapia) 
mayert and Lophorina (Astrapia) stephaniae which replace each other 
around long. 144°E (Mts. Hagen and Giluwe). Mts. Hagen and Giluwe 
also have the easternmost known colonies of Archboldia papuensis, 
which then apparently disappears again for 350 miles to the west until 
Mt. Wilhelmina is reached. The eastern and western semispecies 
Lophorina (Parotia) lawesi and Lophorina (Parotia) carolae also prob- 
ably meet in the Eastern Highlands, but the details are still unknown. 
The only midmontane species which appears to be represented in the 
Eastern Highlands by well-marked eastern and western races is Pene- 
othello sigillatus. ‘Vhree other midmontane species (Coracina caeruleo- 
grisea, Sericornis nouhuysi, and Paradisaea rudolphi) are represented 
in the Eastern Highlands by thinly differentiated eastern and western 
races which intergrade clinally. In the cases of three species (Lophorina 
(Astrapia) stephaniae, Melidectes rufocrissalis, and Melidectes bel- 
fordi) the race on the outlying Schrader Range differs from that in 
the remainder of the Eastern Highlands. 

For analysis of subspecific affinities the Eastern Highlands avifauna 
will be broken down into five somewhat arbitrary categories based on 
altitude, since several different patterns emerge: 

1. Alpine species: species confined to alpine gre assland or the adyja- 
cent forest edge, rarely descending below 10,000 ft in the Eastern High- 
lands. ‘These species live only on the highest mountains in New 
Guinea and show the highest degree of endemism, as expected from 
the broken and isolated nature of their habitat. Of the seven alpine 
species in the Eastern Highlands, one (Melidectes princeps) is an en- 
demic semispecies; three (Megalurus timoriensis montanus, Turdus 
poliocephalus erebus, Oreostruthus fuliginosus hagenensis) are repre- 
sented by endemic subspecies, the latter two nearest the southeastern 
New Guinea forms; two (Petroica bivattata bivittata and Melidectes 
fuscus fuscus) belong to the southeastern New Guinea race, while the 
western New Guinea race differs; and one (Anthus gutturalis rhodo- 
dendri) belongs to the Huon Peninsula race, which is nearer the south- 
eastern New Guinea race than the western New Guinea race. The 
reason for these southeastern affinities of the alpine avifauna of the 
Eastern Highlands is probably that the alpine grasslands of south- 
eastern New Guinea are less distant than those of the Snow Mountains 
of western New Guinea. 

2. Midmontane species: birds that do not descend below 5,000 ft, 


48 


FEATURES OF THE EASTERN HIGHLANDS 


excepting alpine species, which have already been considered. Grass- 
land and swamp species will also be considered separately (pp. 71-72). 

Twenty-seven midmontane species provide no indication of Z00- 
geographical affinities, either because all New Guinea populations 
belong to one race, or else because all Central Range populations 
belong to one race and differentiation occurs only on isolated moun- 
tain “islands” (Vogelkop, Huon Peninsula, etc.). Of the remaining 
species, ten (Psittacella picta excelsa, Psittacella madaraszi hallstromt, 
Epimachus meyeri bloodi, Cnemophilus (Loria) loriae amethystina, 
Cnemophilus macgregorii sanguineus, Archboldia papuensis sanfordi, 
Daphnoenositta miranda kuboriensis, Melidectes rufocrissalis thomas, 
Ptiloprora guisei uwmbrosa, Zosterops novaeguineae wahgiensis) are 
represented by valid endemic subspecies, with two additional endemic 
subspecies on the Schrader Range (Lophorina (Astrapia) stephaniae 
feminina and Melidectes belfordi schraderensis). In the cases of 19 
species of which there are two races, a western and an eastern race, on 
the Central Range, racial determinations are available for the popula- 
tions of the Snow Mountains (about 400 miles west of the Eastern 
Highlands), ‘Velefolmin (about 200 miles west of the Eastern High- 
lands), the Eastern Highlands, and the Wharton Range of southeastern 
New Guinea (about 200 miles east of the Eastern Highlands). In eight 
of these 19 cases the racial division falls between southeastern New 
Guinea and the Eastern Highlands; in five cases, between the Eastern 
Highlands and ‘Telefolmin; and in six cases, between ‘Telefolmin and 
the Snow Mountains. In the four additional cases mentioned on p. 48, 
western and eastern races divide within the Eastern Highlands. ‘The 
Eastern Highlands population of Pachycephala modesta belongs to 
the race of the Huon Peninsula mountain “island,” and the south- 
eastern and ‘Telefolmin populations on the Central Range are both 
racially distinct. 

‘Thus, almost all geographic variation of midmontane species on the 
Central Range is east-west variation, and affinity decreases with in- 
creasing distance. ‘Vhere are somewhat closer affinities with the popula- 
tions to the east in southeastern New Guinea than with the more 
distant Snow Mountains of western New Guinea, as concluded pre- 
viously by Mayr and Gilliard (1954, p. 329) and as also true of the 
alpine avifauna. Except for the three isolates of the Schrader Range 
(p. 48), there are no racial differences between the northern and 
southern slopes. ‘his is as one would expect, since the Central Range 
extends much further east-to-west than north-to-south and presents no 
major barriers to a midmontane species. ‘The dissected terrain consists 
of mountains separated by valleys which provide minor barriers and 
whose floors along the watershed divide lie at 5,000 ft or higher. A 
species will therefore find suitable habitat patchier the higher its 
altitudinal range lies, and the group with the highest percentage of 
differentiated forms is the alpine avifauna. 


49 


FEATURES OF THE EASTERN HIGHLANDS 


3. Tropical species: birds ranging from sea level up to a ceiling 
which is lower than 5,000 ft. Since the Central Range has no passes 
under 5,000 ft, it acts as a barrier which completely stops direct contact 
between populations in the northern New Guinea lowlands and 
southern New Guinea lowlands. Two lengthy indirect paths are avail- 
able for north-to-south gene flow: around the tip of southeastern 
New Guinea in the extreme east, and across the Geelvink Gap or 
around the Vogelkop in the extreme west. Thus, the populations of 
tropical species form a continuous or broken ring in the lowlands 
around the periphery of New Guinea. The tropical avifauna on the 
southern slopes of the Eastern Highlands is well known taxonomically 
as a result of my collections and those of Schodde and Hitchcock, 
whereas little material from below 5,000 ft on the northern slopes 
has been evaluated taxonomically. ‘The following comments therefore 
apply only to the southern slopes unless stated otherwise, and mainly 
to my material from the Karimui area and Okasa. ‘The conclusions 
reached by Schodde and Hitchcock concerning Lake Kutubu will be 
cited separately for comparison. 

‘The races of 42 tropical species replace each other consecutively in 
simple fashion as one proceeds around the lowlands periphery of New 
Guinea. There are, of course, other species in which all New Guinea 
lowlands populations belong to the same race. Regarding east-west 
differences, there are 24 of these 42 cases in which the southeastern, 
Eastern Highlands, and southwestern populations belong to the same 
race; 1] cases in which one race occurs in southwestern New Guinea, 
the Fly River, and Eastern Highlands and a different race in south- 
eastern New Guinea; five cases in which one race occurs in south- 
western New Guinea and on the Fly River and a different one in the 
Eastern Highlands and southeastern New Guinea; and two cases in 
which one race occurs in southeastern New Guinea, the Eastern High- 
lands, and part of the Fly River, while a different race occurs on 
another part of the Fly River and in western New Guinea. Thus, the 
Karimui-Okasa avifauna is slightly closer to that of the Fly River to 
the west than to that of southeastern New Guinea to the east, as 
Schodde and Hitchcock (1968, p. 11) also showed for the Lake Kutubu 
avifauna. Regarding north-south differences, there are four instances 
(the Goura superspecies, the Chalcopsitta superspecies, the Psittacult- 
rostris superspecies, and the Paradisaea raggiana-P. minor superspecies) 
in which one semispecies occurs in southern New Guinea and the 
Eastern Highlands, a different semispecies in northern New Guinea; 
34 cases in which one subspecies occurs in southeastern New Guinea 
and the Eastern Highlands, a different subspecies in northern New 
Guinea; only five cases where the southern New Guinea, northern New 
Guinea, and Eastern Highlands populations all belong to the same 
subspecies; and no instance in which the Eastern Highlands population 
belongs to a northern New Guinea race and differs from a southern

New Guinea race. Thus, the affinities of the avifauna on the southern 
slopes of the Eastern Highlands are exclusively southern, as expected. 
That north-south differentiation is more frequent than east-west dif- 
ferentiation is also as expected, since the distances within the southern 
New Guinea lowlands or northern New Guinea lowlands are less (and 
the opportunities for gene flow therefore greater) than between 
northern and southern New Guinea around the eastern and western 
tips of the Central Range. 

Gilliard, Gyldenstolpe, and Shaw-Mayer obtained specimens of seven 
tropical species from the northern slopes of the Eastern Highlands. 
These all belong to northern semispecies (Goura victoria, Psittaculi- 
rostris edwardsi, Paradisaea minor) or subspecies (Gallicolumba ruft- 
gula septentrionalis, Ceyx azureus ochrogaster, Lophorina (Cicin- 
nurus) regia similis, and Ailuroedus buccoides geislerorum). 

Four tropical species are represented by endemic subspecies which 
probably have narrow ranges on the southern slopes of the Eastern 
Highlands (Domicella lory somu, Aegotheles bennetti terborghi, Rhi- 
pidura leucothorax clamosa, Myzomela eques karimuitensis). 

A different pattern of variation appears in four other tropical species: 
one race is widespread over most of New Guinea, and a different race 
is confined to the Fly River lowlands. ‘The Eastern Highlands popula- 
tion belongs to the widespread race in three cases (Crateroscelis murina 
murina, Microeca flavovirescens cuicui, Myzomela nigrita meyert) and 
to the Fly River race in one case (Amaurornis olivaceus ruficrissum). 

Finally, there are three cases in which the racial affinities of the 
Eastern Highlands population are neither with southeastern New 
‘Guinea directly to the east nor with the Fly River directly to the west, 
but with the southern slopes of the Snow Mountains farther to the 
west, giving a checkerboard distribution (Coracina melaena melaena, 
Pitohui ferrugineus ferrugineus, Meliphaga flaviventer rubiensis). 

4. Hill forest species: birds whose ceilings lie below 5,000 ft but 
which do not descend as far as sea level. Just as for tropical species, 
the Central Range is a complete barrier, except at its ends, to the 
north-south movement of birds in this category. Consideration. is 
again limited to forms on the southern slopes of the Eastern Highlands 
unless stated otherwise. 

Eleven hill forest species show no geographical variation on the 
Central Range. In nine species variation fits a simple east-west and/or 
north-south pattern. Regarding east-west differences, the southeastern, 
Eastern Highlands, and southwestern (i.e., southern slopes of the 
Snow Mountains) populations belong to the same race in three cases; 
in five cases the southeastern and Eastern Highlands populations be- 
long to one race, the southwestern population to another; and in one 
case (Pachycephala hyperythra) the southeastern and Eastern High- 
lands populations belong to the same race, but the species is absent 
from southwest New Guinea. ‘The hill forests at the head of the Fly

River cannot be included in this comparison because they are virtually 
unexplored ornithologically. Regarding north-south differences, the 
Eastern Highlands and southeastern (or southern) populations belong 
to the same race in all nine cases, while the species is absent from 
northern New Guinea in one case (Meliphaga auga) and is represented 
by a different population in northern New Guinea in all eight other 
cases. In three instances (Manucodia (Phonygammus) keraudrenit, 
Lophorina (Diphyllodes) magnifica, Ailuroedus crassirostris) Gilliard 
or Gyldenstolpe took specimens from the northern slopes of the Eastern 
Highlands and found them to belong to the northern race. Thus, the 
main pattern of geographic variation for hill forest species in the 
Eastern Highlands is identical to that for tropical species. 

More complex patterns are met in four hill forest species. Pachycare 
flavogrisea shows clinal east to west variation, and it proves convenient 
to recognize the boundary between two races as occurring in the 
Eastern Highlands. Peneothello bimaculatus is represented by one race 
in the northwestern, southwestern, Eastern Highlands, and southern 
slopes of southeastern New Guinea, by another race on the northern 
slopes of southeastern New Guinea and on the Huon and Adelbert 
“north mountain islands.” ‘The situation is reversed for Zosterops 
atrifrons, of which the populations of the Eastern Highlands (southern 
slopes) and the northern slopes of southeastern New Guinea are con- 
racial, while the populations of the southern slopes of southeastern 
New Guinea and the southwest are racially distinct. Finally, Pachy- 
cephalopsis poliosoma from the Eastern Highlands (southern slopes) 
proves, surprisingly, to belong to the race albigularis from the northern 
slopes at the western extremity of the Central Range, with distinct 
races intervening in southeastern, southwestern, and northeastern New 
Guinea. ‘There are no endemic hill forest subspecies in the Eastern 
Highlands. 

5. Birds ranging both above and below 5,000 ft. Only five species 
in this category exhibit north-south racial differences in eastern New 
Guinea. ‘Three populations (Cacomantis variolosus oreophilus, Meli- 
phaga orientalis facialis, Melanocharis striativentris  striativentris) 
belong to the southern race, two (Opopsitta diophthalma festetichi, 
Trichoglossus haematodus intermedius) to the northern race. ‘The ceil- 
ings of these five species vary locally between about 5,500 and 6,800 ft, 
and the number of north-south passes at these altitudes is limited, so 
that the Central Range, although not a complete barrier to north-south 
gene flow, is still somewhat of a barrier. 

Simple east-to-west variation involving two races on the Central 
Range is encountered in six cases. ‘The division falls between south- 
eastern New Guinea and the Eastern Highlands in three cases (Ralli- 
cula forbesi, Alisterus chloropterus, Pachycephala soror), between the 
Eastern Highlands and ‘Telefolmin in one case (Dicaeum geelvin- 
kianum), and between Telefolmin and the Snow Mountains in two

cases (Cacomantis castaneiventris, Amblyornis macgregoriac). In two 
instances (Coracina caeruleogrisea, Paradisaea rudolpht) eastern and 
western races meet within the Eastern Highlands. 

The Eastern Highlands populations of three species belong to 
endemic subspecies (Caswarius bennettii shawmayeri, Tregellasta leu- 
cops wahgiensis, Paradisaea rudolphi margaritae, plus Lophorina su- 
perba pseudoparotia on the Schrader Range). . 

In two instances (Lophorina superba latipennis, Melanocharis longt- 
cauda captata) Eastern Highlands populations belong to the subspecies 
of the Huon Peninsula mountain “island” and differ racially from the 
Central Range populations to the east and west. These patterns almost 
surely arose from populations differentiating in the Eastern Highlands 
and then invading the Huon Peninsula, not yice versa (cl., also, 
Pachycephala modesta, p. 49). 

The Eastern Highlands population of Meliphaga orientalis is derived 
from the southern slopes of western New Guinea (facials) rather than 
the southern slopes of southeastern New Guinea (orientalis) and differs 
from the northwestern (citreola) and northeastern (beck) populations. 

Colluricincla megarhyncha is represented in the Wahgi Valley by 
the northeastern New Guinea race tappenbecki and on the southern 
slopes of the Eastern Highlands by the Herzog Mountains race nea. 
The populations from southeastern New Guinea and the Fly River 
differ. 

Summary of zoogeographic affinities. ‘Lhe hindrances to gene flow 
implicit in geographic variation result in New Guinea either from 
geographical barriers, hence a discontinuity in the distribution of a 
species, or else simply from distance. ‘he Central Range runs east-west 
and lacks passes under 5,000 ft. For tropical and hill forest species, 
which are absent above 5,000 ft, the Central Range functions as a 
complete or nearly complete barrier, so that there are marked differ- 
ences between northern and southern populations, as well as east-west 
variation resulting from distance. For midmontane species, which do 
not descend below 5,000 ft, north-south population differences are 
virtually nonexistent, and variation is east-to-west. ‘The higher a species’ 
altitudinal lower limit, the patchier the environment becomes to the 
species, so that the highest proportion of endemic forms is encountered 
among alpine birds. Eastern and western distributional limits of species 
and semispecies can be used to divide the Central Range into three 
sections, of which the Eastern Highlands as defined in this monograph 
is one. 


AVIFAUNA OF THE KARIMUI BASIN 


The unusual bird distribution patterns in the Karimui Basin re- 
quire separate discussion. As already mentioned, Karimui is a flat basin 
with a floor lying at about 3,500 ft, and is effectively sealed off from 


53 


FEATURES OF THE EASTERN HIGHLANDS 


the outside by a ring of mountains. The Karimui avifauna is marked 
by the presence of many lowland species whose altitudinal ceiling else- 
where lies considerably below 3,500 ft; by the absence or rarity of some 
hill forest species normally encountered at this altitude; and by the 
presence of three strikingly distinct endemic forms. The avifauna we 
found at Karimui Patrol Post (3,650 ft) contrasted with that of the 
Okasa forest (3,550-4,250 ft), which is at the same altitude but in hilly 
terrain typical for this altitude in most of New Guinea. 

The following 26 or 27 lowland forest species were present at Kari- 
mui but rarely reach this altitude elsewhere in New Guinea. Some of 
these species, in fact, normally disappear as soon as one leaves the flat 
lowlands at sea level. None was present at the same elevation at Okasa, 
and Schodde and Hitchcock met only 11 at Lake Kutubu despite the 
elevation there (2,450 ft) being 1,200 ft lower than at Karimui Patrol 
Post: Aviceda subcristata, Rallina tricolor, Ptilinopus nanus, Megalo- 
prepia magnifica, Chalcophaps stephani, Charmosyna placentis, Psit- 
taculirostris desmarestt1, Opopsitta gulielmiterti, Geoffroyus geoffroyt, 
Eudynamis scolopacea, Centropus menbeki, Aegotheles bennettii, Hal- 
cyon torotoro, Campochaera sloeti, Coracina boyeri, Sericornis spilo- 
dera, Rhipidura threnothorax, Monarcha chrysomela, Microeca flavo- 
virescens, Poecilodryas placens, Pitohui kirhocephalus, Pitohwui 
ferrugineus, Lophorina (Cicinnurus) regia, Ailuroedus buccoides, My- 
zomela eques, Pycnopygius ixoides, and probably Casuarius casuarius. 

The following nine lowland species of the forest edge, second- 
growth, and open country were present at Karimui somewhat above 
their normal altitudinal ceiling. All were absent at Okasa, but Schodde 
and Hitchcock found all except Circus approximans at Lake Kutubu 
(2,450 ft): Circus approximans, Amaurornis olivaceus, Ptilinopus per- 
latus, Dacelo gaudichaud, Rhipidura leucothorax, Mino dumontii, 
Cracticus cassicus, Dicrurus hottentottus, and Nectarinia sericea. 

The following ten hill forest species which would normally be 
encountered at the elevation of Karimui were absent: Caswarius ben- 
nettii, Charmosyna pulchella, Halcyon megarhyncha, Sericornis arfaki- 
anus, Phylloscopus trivirgatus, Rhipidura atra, Microeca griseoceps, 
Lophorina (Parotia) lawesi, Lophorina superba, and Ailuroedus crassi- 
rostris. In the case of three additional hill forest species expected at 
3,500 ft, one or more immatures were taken at Karimui but no adults: 
Monarcha axillaris, Pachycephala soror, and Manucodia (Phonygam- 
mus) keraudrenin. Adults of five additional hill forest species were 
taken at Karimui but were much rarer than expected at 3,500 ft: 
Tregellasia leucops, Pachycephalopsis poliosoma, Pachycephala leuco- 
stigma, Melidectes torquatus, and Meliphaga orientalis. Fifteen of 
these 18 hill forest species were present at Okasa and include all of 
the commonest Okasa birds. 

In seven of these cases a species unexpectedly present and a species 
unexpectedly absent at Karimui are successive members of an altitudinal

sequence (p. 27), so that the “wrong” member of the sequence was 
present: Charmosyna placentis vs. C. pulchella, Halcyon torotoro vs. 
H. megarhyncha, Sericornis spilodera vs. S. arfakianus, Rhipidura 
threnothorax vs. R. atra, Microeca flavovirescens vs. M. griseoceps, 
Ailuroedus buccoides vs. A. crassirostris, and probably Caswarius casu- 
arius vs. C. bennettii. 

‘Two kinds of evidence indicate that the distributional anomalies at 
Karimui are ultimately due to the flatness of the basin floor. ‘The first 
line of evidence is based on the changes in the avifauna on the lower 
slopes of Mt. Karimui, which rises out of the basin. Near the base of 
Mt. Karimui’s west ridge the basin floor begins to slope gently upward 
as one goes towards the mountain, until at an elevation of 4,200 ft the 
foot of the west ridge is encountered and the mountain abruptly rises 
at a steeper angle. Of the eight altitudinal zones into which I arbi- 
trarily divided Mt. Karimui, the lowest, Zone 1, was on the sloping 
basin edge just at the foot of the ridge and spanned an altitude range 
from 4,000 to 4,200 ft. Although Zone | began at an altitude only 350 
ft above Karimui Patrol Post (3,650 ft), my main collecting station on 
the flat basin floor, all but six of the 26 or 27 lowland forest species 
present at Karimui above their normal ceiling were absent from Zone 
1, and five of these six disappeared as soon as the west ridge was 
reached, i.e., in Zone 2. Conversely, of the 18 hill forest species absent 
or rare on the basin floor, 10 were present and generally common 
already in Zone 1, and seven of the remaining eight appeared in Zone 
2. ‘Thus, the distributional anomalies of the flat basin floor were re- 
versed as soon as sloping terrain was encountered even though there 
had been only a small change in altitude itself. 

‘The second and more striking line of evidence that the anomalous 
lowlands avifauna of the Karimui Basin is due to its flatness was 
provided by the discontinuous altitudinal ranges of at least three hill 
forest species. ‘he flycatcher Rhipidura atra was present on the slopes 
of Mt. Karimui from 4,090 ft upward and was absent on the basin 
floor. When I crossed the mountain wall ringing the basin and de- 
scended into hilly country en route to Soliabeda, Rhipidura atra 
reappeared at 3,230 and 2,770 ft. On the slopes of Mt. Karimui the 
parrot Charmosyna pulchella was present from 4,400 ft upward, and 
the bird of paradise Loboparadisea sericea from 4,000 ft upwards. Both 
were absent on the basin floor but reappeared at Soliabeda, which is 
at 2,000 ft in hilly country. The absence of these three species in the 
basin thus could not have been due to altitude, since they were present 
at both lower and higher altitudes in hilly terrain, and must have been 
due to the flatness. Had more time been spent en route between 
Karimui and Soliabeda, and had the difficulty and circumstances of 
the route not been so unconducive to bird-watching, I suspect that 
similar instances of discontinuous altitudinal distributions would 
have been unmasked in some other hill forest species.

FEATURES OF THE EASTERN HIGHLANDS 


‘The explanation these facts suggest for the anomalous avifauna of 
Karimui is that the flatness of the basin floor has caused it to fill up 
with the rainforest, and hence many of the birds, characteristic of the 
flat lowlands rather than of the hill slopes. This interpretation seems 
reasonable, since the slope governs the effectiveness of drainage and 
hence the plant communities, and since quite a few New Guinea bird 
species (¢.g., Otidiphaps nobilis, Gymnophaps albertisii, Lophorina 
(Diphyllodes) magnifica), are absent from the flat lowlands but present 
in hilly terrain even near sea level. What makes Karimui unique is 
the general ruggedness of New Guinea’s hills and mountains, so that 
one rarely, or nowhere else, finds a flat area at 3,500 ft as extensive 
as at Karimui. 

Three of these isolated populations trapped within the Karimui 
Basin have differentiated to yield strikingly distinct endemic forms, all 
tending towards melanism (Diamond, 1967a). ‘The unique type of the 
owlet-nightjar, Aegotheles bennetti terborghi, not only represents an 
altitudinal record for this lowland rainforest species but also is 25% 
larger in linear dimensions than the other races (hence presumably 
twice as heavy) and much darker. The goshawk Accipiter novaehol- 
landiae exists elsewhere in two color phases, one pure white, the other 
gray and rufous, while the Karimui population is melanistic, being 
uniform dark gray-brown. The mannikin Lonchura_ spectabilis 
gajduseki has buff underparts as opposed to white in other races. ‘The 
distinctness of these endemic forms suggests that strong selective 
pressures are operative at Karimui and that the mountain ring is an 
effective barrier to gene flow for some species. For such species the 
Karimui Basin represents an isolated island of tropical habitat, 
analogous to the evolutionary significance of isolated high mountain 
summits for alpine species. 


ALTITUDINAL DISTRIBUTION 


In this section the results of my altitudinal censuses in the Karimui 
area (Soliabeda, Bomat, Karimui, Mt. Karimui) will be analysed. Pre- 
vious analyses of the altitudinal distribution of New Guinea birds 
include those by Stresemann (1923, pp. 7-15), Archbold and Rand 
(1935, pp. 535-543), and Archbold, Rand, and Brass (1942, p. 285). 

I identified 242 bird species in the Karimui area. Of these, 36 were 
nonforest species, strictly confined to grassland, second-growth, or 
water. Such habitats do not exist on Mt. Karimui, and these 36 species 
are therefore excluded from consideration in the present analysis. Of 
the 206 forest species, there were 40 of which I obtained too few records 
to work out the altitudinal range satisfactorily. 

Figure 4 presents the altitudinal ranges of the 166 forest species for 
which my data are adequate. All altitudinal ranges were assumed to be 
continuous; if a bird was recorded above and below but not at a cer- 


56 


FEATURES OF THE EASTERN HIGHLANDS 


tain elevation, it was assumed to be present at that elevation but to 
have been overlooked. This assumption is probably valid except in 
the cases of a few hill forest species present above and below but not 
in the Karimui Basin (pp. 55-56). Birds present at Soliabeda, my lowest 
station (1,350-2,000 ft), are arbitrarily depicted in Figure 4 either as 
continuing down to sea level or else as having their lower limits at 
Soliabeda, the decision being made on the basis of my ex perience 
elsewhere in New Guinea or on the basis of published information. 
On Mt. Karimui, Zone 1 (4,000-4,200 ft), Zone 2 (4,400-4,750 ft), Zone 
3a (4,750-5,080 ft), Zone 3b (5,080-5,390 ft), Zone 4a (5,390-5,780 ft), 
Zone 4b (5,780-5,960 ft), Zone 5a (5,960-6,250 ft), Zone 5b (6,250-6,500 
ft), Zone 6a (6,500-6,770 ft), Zone 6b (6,770-7,080 ft), Zone 7a (7,080- 
7,280 ft), Zone 7b and 8a (7,280-7,620 ft), and Zone 8b (7,620-8,165 ft, 
the summit) were each considered as units in constructing Figure 4: 
i.e., if a species was recorded anywhere within the unit, it is depicted 
as being present throughout the unit. 

The following conclusions may be extracted from Figure 4: 

l. Species diversity (Fig. 5). “The number of forest species recorded 
at a given altitude is relatively constant at about 100 species from 
3,650 ft (Karimui) and 3,250 ft (Bomai) down to at least 1,350 ft (the 
lower limit of collecting at Soliabeda). On Mt. Karimui the number 
of species decreases regularly with increasing altitude, from 77 at 
4,000-4,200 ft (Zone 1) to 16 in the summit zone (7,620-8,165 ft). Pos- 
sibly some of the difference between the species totals for the lowest 
elevation on Mt. Karamui (77 species) and the three village locations 
at lower elevations (ca. 100 species) is because larger and more diverse 
areas of forest were surveyed at a given elevation at the village locations 
than on Mt. Karimui. The apparent slight maximum in Figure 5 at 
3,650 ft (Karimui) is probably an artifact of more time spent collecting 
at Karimui than at other localities. It should be mentioned again 
that the actual number of forest species is about 25% higher than 
depicted in Figure 5, since ranges for only 166 of the 206 forest species 
in the area were used to construct Figure 5. 

Three factors contribute to the decrease in species diversity with 
altitude depicted in Figure 5. First, with increasing elevation the forest 
becomes more stunted, and MacArthur, Recher, and Cody (1966) have 
shown that bird species diversity among different habitats in the same 
area correlates well with the foliage profile diversity. Second, the total 
area in New Guinea at a given altitude decreases with increasing 
altitude. Over long times, the total number of species that can evolve 
to utilize a given type of habitat should be larger, the greater the 
available area of the habitat, and one would therefore expect fewer 
high-altitude than low-altitude species in New Guinea even if the 
foliage did not change. For example, there is a much greater area of 
alpine grassland, and consequently much greater variety of alpine 
grassland bird species, in the South American Andes than in New

Fic. 5. Species diversity on Mt. Karimui. Each point gives the number of forest 

species recorded at the given elevation. Species diversity decreases with increasing 
altitude. 


Guinea. Third, as discussed previously (p. 24), Mt. Karimui is a 
small, isolated mountain and does not have all the species present on 
larger New Guinea mountains due to drop-outs. Mt. Karimui supports 
the smallest fraction of the available species pool at the highest eleva- 
tions, where the effects of isolation and small land mass are most 
pronounced. 

2. Species with broad altitudinal ranges. Figure 4 shows that most 
species have ranges of less than 5,000 but more than 1,000 feet. Only 
19 species have ranges greater than 5,000 ft, and only six of these 
exceed 6,500 ft. All 19 of these wide-ranging species descend to sea 
level. No montane species (i.e., a species that fails to descend to sea 
level) has a range greater than 4,200 ft. 

Of the 19 wide-ranging species, 12 have no congeners in the Eastern 
Highlands, either because they belong to monotypic genera or else have 
congeners restricted to other islands or other parts of New Guinea. 
This correlation is another expression of the fact that altitudinal 
segregation is the most important ecological sorting mechanism in 
New Guinea that permits sympatry between congeners. Hence species 
without congeners are the ones most likely to have a broad altitudinal 
range. 

3. Species with narrow altitudinal ranges. ‘Vhere are two classes of 
species with ranges narrower than 1,000 feet. One of these consists of 


66 


FEATURES OF THE EASTERN HIGHLANDS 


high altitude species for which Mt. Karimui is barely high enough 
and which can exist only near the summit. For instance, the bird of 
paradise Cnemophilus macgregorii was confined to the top 545 {t, 
and the flowerpecker Paramythia montium was not seen more than 
40 ft below the summit. The other class consists of species whose 
ranges fall in the middle of the mountain and in some cases are com- 
pressed by congeners living at higher or lower altitudes. For instance, 
the total range of the warbler Sericornis arfakianus 1s 600 feet, the 
whistler Pitohui nigrescens is 900 feet, and the bird of paradise 
Manucodia (Phonygammus) keraudrenti is 750 feet. ‘These narrow 
altitudinal bands imply excessively small populations which might 
easily be eliminated by an unusual environmental fluctuation (a poor 
breeding season, disease, expansion of another species, etc.). Such 
species are most like to drop out on Mt. Karimui or to have difficulty 
becoming established in the first place. 

4. Altitudinal “zones.” If the altitudinal limits of many species 
tended to coincide, this fact could be expressed by recognizing altitudi- 
nal zones of faunal distribution. If limits of many species did not 
coincide, zones would be arbitrary and not worth recognizing. ‘This 
question is examined in Figures 6-9. 

Figure 6 plots, as a function of altitude, the absolute number of 
species per 100 feet reaching their upper altitudinal limit in a given 
zone. Figure 7 reexpresses the same numbers as the percentage of the 
species in a given zone which reach their upper limit in each 100 feet of 
the zone. It is apparent that few species (only seven) reach their ceilings 
below Karimui (3,650 ft). ‘here would, of course, be some further 
species present at sea level whose ceilings lie below Soliabeda and 
which were therefore not observed in these studies. Species ceilings 
are well distributed from 3,650 ft to the summit, with some concentra- 
tion at three maxima: viz., between the flat basin floor at Karimui 
(3,650 ft) and the lowest slopes of Mt. Karimui (4,000 ft), where 35 
species drop out; at the moss level (6,500 ft), where nine species (20%, 
of the avifauna at 6,350-6,500 ft) drop out; and above 7,280 ft, where 
13 species drop out before the summit is reached and 16 species con- 
tinue up to the summit and necessarily drop out there. Seventy-two 
species have ceilings between 4,000 ft and the moss level on Mt. 
Karimui, but there are no well-defined maxima in this range. 

Figures 8 and 9 are the corresponding figures for the absolute and 
relative numbers of species reaching their lower limits per 100 feet. 
Below Bomai (3,250 ft) species drop out at a low rate (24 species, or 
somewhat less than one species or 19% of all species present dropping 
out per 100 vertical feet). Above Bomai the frequency of species lower 
limits, whether expressed absolutely or relatively, first increases and 
then decreases with increasing elevation and has a very broad maxi- 
mum around 5,000 ft. “Phe apparent increase again at the highest 
altitude (farthest right-hand point of Figures 8 and 9) reflects the

Fic. 6. Absolute frequencies of the upper altitudinal limits of forest species on 
Mt. Karimui, as a function of altitude. The ordinate gives the number of species 
whose upper altitudinal limits lay in a vertical band of 100 feet centered about 
the altitude given on the abscissa. Species ceilings are well distributed over the 
whole mountain above about 3,500 ft, with an accumulation at 4,000 ft (transition 
between flat basin floor and hill slopes) and a lesser accumulation at 6,500 ft (the 
moss level). 


appearance of only two new species in the depauperate avifauna of 
Zone 8. 

One could therefore speak of a relatively uniform tropical zone ex- 
tending from the Karimui Basin (3,650 ft) down to Soliabeda (1,350- 
2,000 ft) and (by extrapolation) to sea level, where the total number 
of species remains quite constant and few species have their ceilings 
or lower limits. Subdivision of Mt. Karimui (>4,000 ft), which lies 
above this tropical zone but still contains a majority of tropical species 
for some distance above 4,000 ft, into several zones is not possible. 
Instead, new species gradually come in with increasing altitude, with 
a very broad maximum around 5,000 ft, and species gradually reach 
their ceilings, with a slight maximum at the moss level ang. an ac 
celeration towards the summit. 

Previous authors have discussed a “sharp avifaunal break which 
occurs at about 4,500-5,000 ft in the altitudinal zonation of New 
Guinea birds” (Gilliard and LeCroy, 1961, p. 22; cf., also, Stresemann, 
1923, who places the break at 1,500 m = 4,920 ft, and Archbold and 
Rand, 1935, who place it at 1,700 m = 5,580 ft). In the field I had the 
strong impression that such a sharp break did exist. ‘This impression 
was due partly to the rapid species turnover on Mt. Karimui (e.g., only 
FZ species are found at both 3,650 and 6,000 ft); and partly because

some common and conspicuous species reached their upper limit 
(Crateroscelis murina, Pachycephalopsis poliosoma, Meliphaga flavi- 
venter) or lower limit (Crateroscelis robusta, Sericornis perspicillatus, 
Rhipidura albolimbata, Peneothello cyanus) near 5,000 ft. However, 
the detailed results presented in Figures 6-9 show that one cannot speak 
of a sharp break at 5,000 ft on Mt. Karimui: there is no increased 
frequency of ceilings and only a gentle maximum in frequency of lower 
limits. If one had to designate any break on Mt. Karimui, it would be 
at 3,650-4,000 ft, and even that one would involve only a minority of 
the species present. 

‘These findings concerning Mt. Karimui cannot be assumed valid 
for other New Guinea mountains without further testing, since dis- 
tributional patterns on Mt. Karimui are unusual in three respects. 
First, the intrusion of the flat basin has caused a conspicuous tropical 
element to persist in undisturbed forest up to 3,650 ft to a degree for 
which I know of no parallel elsewhere in New Guinea. Elsewhere I

would not expect so little change in the avifauna between 1,350 and 
3,650 ft and so marked an accumulation of species ceilings at 3,650- 
4,000 ft, i.e., so marked a tropical “zone.” Second, moss forest descends 
lower on Mt. Karimui than on the highest central peaks of New 
Guinea, though it descends still lower on isolated peaks nearer the 
sea. The avifauna at 7,500 ft on Mt. Karimui is similar to that at 
10,000 ft on Mt. Michael, and birds compressed between 4,000 ft and 
6,500 ft on Mt. Karimui would range from 3,000 to 8,500 ft on larger 
mountains. Finally, Mt. Karimui is too low to support the depauperate 
New Guinea alpine grassland and timberline avifauna. 


BREEDING NON-FoREST AVIFAUNA 


Species Composition 

In areas undisturbed by man the original vegetation is forest over 
most of New Guinea. The only extensive area in which the climax 
vegetation is not forest is the low-rainfall savanna strip on the south 
coast, where most birds are Australian rather than typical New Guinea 
species. Elsewhere original non-forest vegetation consists of alpine 
orassland, naturally disturbed areas (due to landslides, earthquakes, or 
fallen trees), swamps and marshes, and the edges of streams and rivers.

Fic. 9. Relative frequencies of the lower altitudinal limits of forest species on 
Mt. Karimui, as a function of altitude. The ordinate gives the percentage of species 
present at a given elevation whose lower altitudinal limits lay in a vertical band 
of 100 feet centered about the altitude given on the abscissa. 


The total unforested area in undisturbed regions at middle elevations 
is minute. As a result the breeding non-forest avifauna of the Eastern 
Highlands is limited in variety (about 80 species in all types of non- 
forest habitats at all elevations above 1,350 ft). In areas settled by man 
non-forest habitat is greatly increased. It is of interest to examine 
the list of breeding bird species characteristic of each of six types of 
non-forest habitat in the Eastern Highlands. It should be remembered 
(see pp. 79-80) that migrants from outside New Guinea make a con- 
spicuous but nonbreeding contribution to the non-forest avifauna, 
especially to category 6 (open country and forest edge). 

1. Alpine grassland.—Alpine grassland occurs naturally above about 
11,500 ft and is separated by a forest belt from the man-made mid- 
montane grassland, whose upper limit varies locally up to about 
8,000 ft. Only four species occur in the alpine grassland, all repre- 
sented by endemic subspecies: the pipit Anthus gutturalis, which is 
strictly confined to the grassland; the thrush Turdus poliocephalus 
and the grass finch Oreostruthus fuliginosus, which live in the grass- 





71 


FEATURES OF THE EASTERN HIGHLANDS 


land and adjacent forest edge (Oreostruthus barely gets into the grass- 
land and is mainly in the forest edge); and the grass warbler Megalurus 
tumorensis, which has isolated and racially distinct populations in low- 


land, midmontane, and alpine grassland. 


2. Water.—Bodies of water consist of a few lakes (Kutubu, Tebera, 


Kandep, and the small alpine lakes on Mt. Wilhelm), a few small 
rivers, and numerous brooks and small streams. The breeding water 
birds are the grebe Podiceps novachollandiae, the ducks Anas super- 
ciliosa and Salvadorina waigiuensis, and the kingfisher Ceyx azureus. 
All occur in the much more extensive waterways of the lowlands 
except for Salvadorina. There are two strictly riparian passerines, both 
absent from the lowlands: the flycatcher Monachella muelleriana and 
the ‘Yorrent Lark, Grallina bruijni. The duck Nettapus coromande- 
lianus has been reported from Lake Kandep, the duck Anas gibberi- 
frons from the Wahgi River and Mt. Giluwe, and several cormorants 
and herons at Lake Kutubu, but I do not know if these species breed. 
The cormorant Phalacrocorax melanoleucos has been found breeding 
on the Baiyer River. Salvadorina waigiuensis is apparently the sole 
aquatic bird in the alpine lakes of Mt. Wilhelm. 

3. Swamps.—Small swamps border watercourses and harbor up to 
five rails: Rallus philippensis, Porzana tabuensis, Porzana pusilla (one 
locality), Porphyrio porphyrio, and Gallinula tenebrosa (one record). 
All five species have wide ranges outside New Guinea. P. pusilla is 
confined to middle elevations in New Guinea, and Rallus phillippensis 
and Porzana tabuensis are represented in the Eastern Highlands by 
thinly differentiated endemic subspecies. 

4. Air.—In the air, remote from forest, are 14 species, of which six 
swifts and swallows take aerial food, while eight hawks merely hunt 
from the air. Six of these 14 species—the hawk Henicopernis longi- 
cauda, the swifts Collocalia esculenta, C. hirundinacea, and C. white- 
head, the crested swift Hemiprocne mystacea, and the wood swallow 
Artamus maximus—also occur over hill or montane forest and streams 
in areas undisturbed by man; Henicopernis also hunts inside the forest. 
I suspect that seven of the other species have begun to appear in the 
Eastern Highlands from the lowlands only since man began extensive 
clearing of the forest, viz., the hawks Milvus migrans, Haliastur indus, 
Accipiter fasciatus, Circus spilonotus, Circus approximans (only Kari- 
mui), and Falco berigora and the swallow Hirundo tahitica. The hawk 
Elanus caeruleus, whose range includes much of Africa and Eurasia, is 
confined in New Guinea to extensively deforested areas at midmontane 
elevations. The New Guinea population is subspecifically distinct (E. c. 
wahgiensis) but has never been found in areas of New Guinea un- 
disturbed by man, so that its origins are obscure. 

5. Midmontane grasslands—Midmontane grasslands in their pres- 
ent extent are a product of native agriculture. If one defines grassland 
species as those that live in the grass and do not require other elements 


12, 


FEATURES OF THE EASTERN HIGHLANDS 


(trees, fences, bushes) for perches, then 16 grassland species occur 1M 
the Eastern Highlands. Most of these 16 species are confined in the 
Eastern Highlands to areas with extensive destruction of forest by man. 
Seven of these also occur in the lowlands and do not have endemic 
midmontane races: the cuckoo Centropus phasianinus, the nightjar 
Caprimulgus macrurus, the lark Mirafra javanica, the grass warblers 
Acrocephalus arundinaceus and Cisticola exilis, the bowerbird Chlamy- 
dera lauterbachi, and the mannikin Lonchura grandis (only at Okasa). 
While Chlamydera lauterbachi is widespread, the other six species are 
each known only from a few localities or areas in the Eastern High- 
lands, making one suspect that they have just begun to colonize the 
midmontane grasslands. Six grassland species also occur in the low- 
lands, but the midmontane population is subspecifically distinct: the 
quail Synoicus ypsilophorus and Coturnix chinensis, the bustard-quail 
Turnix maculosa, the wren-warbler Malurus alboscapulatus (two races), 
the grass warbler Megalurus timoriensis, and the mannikin Lonchura 
spectabilis (two races). The races Synoicus ypsilophorus lamonti, 
Turnix maculosa gilwwensis, Megalurus timoriensis wahgiensis, Mal- 
urus alboscapulatus kutubu, and Lonchura spectabilis gajduseki are 
endemic to the Eastern Highlands, while Coturnix chinensis novae- 
guineae is shared with the midmontane grasslands of western New 
Guinea, Malurus alboscapulatus mafulu is shared with the midmon- 
tane grasslands of southeastern New Guinea, and Lonchura spectabilis 
wahgiensis is shared with the midmontane grasslands of the Huon 
Peninsula. The remaining three species—the rail Rallus pectoralis, 
the owl Tyto capensis, and the pipit Anthus novaeseelandiae—have 
wide geographic ranges outside New Guinea, but the New Guinea 
populations are subspecifically distinct and confined to the midmontane 
grasslands (absent from the lowlands, except for one localized popula- 
tion of the pipit). 

6. Open country and forest edge ‘Open country and forest edge”’ 
may be used as the name for a category that excludes swamps and 
pure grassland but includes native gardens, grassland with occasional 
trees or fences to provide perches, open vegetation around villages and 
towns, planted groves of trees remote from forest, regenerating vegeta- 
tion in a cleared and fallow area, and the forest edge. Many forest 
species may, of course, also be found at the forest edge, but if discussion 
is restricted to birds regularly found remote from forest and to birds 
which are much commoner at the forest edge than in the forest interior, 
then one arrives at a somewhat arbitrary list of 33 species. About 17 of 
these species are encountered above 5,000 ft, 16 only below 5,000 ft, 
and 24 at sea level. ‘This list is probably not exhaustive, since I spent 
little time in towns remote from forest. 

Two of these 33 species (the cuckoo Cacomantis pyrrhophanus and 
the warbler Gerygone ruficollis) occur only above 5,000 ft. Both may 
be found in the interior of undisturbed forest but have become much 


73 


FEATURES OF THE EASTERN HIGHLANDS 


commoner in trees of towns and gardens, perhaps because they have 
so few competitors in these habitats. 

Five species are absent from the lowlands and live mainly between 
about 3,000 and 7,000 ft: the flycatcher Peltops montanus, the shrike 
Lanius schach, and the honeyeaters Myzomela adolphinae, Melidectes 
torquatus, and Meliphaga auga. Four of these five species (Peltops 
montanus and the three honeyeaters) are endemic to New Guinea and 
also live in forest or in natural forest edge habitats, so that their origin 
poses no problems. Lanius schach is confined to man-made habitats 
(gardens and grassland with perches) and is represented in New Guinea 
by an endemic race of a species with a widespread extralimital range. 

‘Ten species (the pigeon Macropygia amboinensis, the parrot Tricho- 
glossus haematodus, the cuckoo Cacomantis variolosus, the Barn Owl, 
Tyto alba, the chat Saxicola caprata, the flycatchers Rhipidura rufi- 
ventris and Rhipidura leucophrys, the whistlers Pachycephala ruft- 
ventris and Colluricincla harmonica, and the bird of paradise super- 
species Paradisaea minor-P. raggiana) occur in the lowlands and are 
found only below 5,000 ft in undisturbed areas but have ceilings, 
depending on the species, between 5,500 and 7,000 ft in settled areas. 
Four of these species (the pigeon, the parrot, the bird of paradise, and 
Rhipidura rufiventris) are regularly found in forest up to about 4,500 
ft, so that only a small upwards step was required to colonize the 
settled areas above 5,000 ft. ‘The cuckoo is mainly, the other five 
species are strictly, forest edge and open country birds, and all six are 
absent at elevations above a few thousand feet in undisturbed areas. 

The remaining 16 species range from the lowlands up to ceilings 
varying between about 2,000 and 4,000 ft: the rail Amaurornis ollt- 
vaceus, the kingfisher Dacelo guadichaud, the roller Ewrystomus 
orientalis waigiouensis, the cuckoo-shrikes Coracina papuensis and C. 
tenuirostris, the wren-warbler Todopsis cyanocephala, the warbler 
Gerygone magnirostris, the flycatchers Peltops blainvilli, Rhipidura 
leucothorax, and Myiagra alecto, the starling Mino dumontii, the 
oriole Oriolus szalayi, the butcherbird Cracticus cassicus, the drongo 
Dicrurus hottentottus, the sunbird Nectarinia sericea, and the honey- 
eater Philemon novaeguineaec. Three if these species (Dacelo gaudi- 
chaud, Oriolus szalayi, Philemon novaeguineae) also live in the forest 
interior, while Amaurornis olivaceus lives in garden edges and grass 
and the remaining species live at the forest edge or in partly cut forest. 
For most of these species the ceilings in the disturbed areas of the 
Eastern Highlands (2,000-4,000 ft) are somewhat above the ceilings in 
undisturbed areas. 


Origin of the Non-Forest Avifauna of the Eastern Highlands 


There appear to have been five sources of the nonforest bird species 
in the Eastern Highlands. 
1. Evolution in pre-existing specialized habitats—Three types of 


74 


FEATURES OF THE EASTERN HIGHLANDS 


specialized habitats, inhabited by specialized birds already listed, must 
always have existed in the Eastern Highlands: alpine grassland, bodies 
of water, and swamps. ‘The total areas occupied by these specialized 
habitats are very small now, have been little affected by man, and 
probably have not been significantly larger in recent geological history, 
except for expansion of alpine grassland during cooler parts of the 
Pleistocene. The endemic montane species and subspecies now living 
in these habitats have had an indefinite amount of time to evolve in 
them. The very small number of such endemic montane forms (four 
in alpine grassland, three on waterways, two in swamps) 1s what one 
would expect from the small area of such habitats in the New Guinea 
mountains. Some of the water and swamp species also live in the low- 
lands and are not represented by endemic montane races. ‘They prob- 
ably evolved mainly in the lowlands, where the area occupied by 
waterways and swamps is larger. 

2. Evolution in pre-existing forest edge habitats —Even in montane 
areas undisturbed by man, natural forest edge habitats adjacent to 
open spaces exist, notably in permanent form along streams, but also 
transiently on steep slopes with landslides, as a result of trees falling 
in the forest, and as a result of earthquakes. ‘The total area of forest 
edge habitat in undisturbed montane areas is very small and increases 
vastly in regions disturbed by man. ‘The population densities of forest 
edge species in settled regions are now high in many cases, but before 
native agriculture these species must have evolved and eked out “a 
precarious existence in the shifting bits of habitat suitable for them” 
(Rand and Brass, 1940, p. 377). As illustrations I shall cite several 
instances in which I obtained records in montane areas remote from 
human disturbance for birds which are completely absent from the 
interior of closed forest. At the Sena River the Crested Swift, Hemz- 
procne mystacea, perched in riverside trees and sallied into the open 
space over the stream. In the river gorges below Karimui, Bomai, and 
Soliabeda and on the Sena River I met the swift Collocalia esculenta 
hawking over the streams, and JI have seen both C. esculenta and C. 
hirundinacea over ravines and the sides of forested ridges on Mts. 
Karimui, Michael, Menawa, and Turu. On Mt. Menawa I saw the 
wood swallow Arfamus maximus perched in trees on the crest of a 
steep forested ridge. The butcherbird Cracticus cassicus was present 
in the river gorges below Soliabeda and Bomai. ‘The flycatcher Peltops 
montanus sallied over the Sena River from trees on the banks, and I 
have regularly found it in trees on the crests of steep mountain ridges 
(Mts. Karimui, Somoro, Nibo, Menawa). Once I saw the sunbird 
Nectarinia sericea in the tree canopy on the steep slopes of the Nami 
Gorge in the Karimui Basin. I found a nest of the honeyeater Meli- 
phaga auga in a bamboo thicket near a small stream below Soliabeda. 

3. Evolution in forest—Five of the seven montane species that 
occur in open country and forest edge habitats and do not descend to 








75 


FEATURES OF THE EASTERN HIGHLANDS 


sea level also occur in the interior of montane forest, where they 
undoubtedly evolved. These are Cacomantis pyrrhophanus, Gerygone 
ruficollis, Pitohui dichrous, Myzomela adolphinae, and Melidectes 
torquatus. Gerygone ruficollis and Melidectes torquatus are very un- 
common in the forest interior but are the two most abundant species 
in trees in open country around 5,000 ft, and their numbers must have 
undergone an enormous explosion as a result of native agriculture. 

4. Recent expansion from the lowlands.—Because there are many 
more rivers, marshes, and swamps in the lowlands than in the moun- 
tains, more species of forest edge and grassland birds have evolved in 
the lowlands than in the mountains. With the recent spread of open 
country in the mountains, some lowlands species may have begun to 
colonize the midmontane open country only recently. Though it is, 
of course, impossible to be certain about the time of arrival, a recent 
arrival must be suspected for species whose midmontane populations 
are not subspecifically distinct and which are absent from the moun- 
tains in areas undisturbed by man, particularly if their distribution in 
midmontane open country is very local. In this category probably fall 
the swallow and six hawks listed on p. 72, most of the seven grassland 
birds listed on p. 73, and most of the 26 open country and forest edge 
birds listed on pp. 73-74 which are shared with the lowlands and are 
not subspecifically distinct. 

5. Rapid recent evolution?—The evolution of non-forest lowland 
species poses no problems because there is a modest amount of non- 
forest habitat in the lowlands and these species can be seen in these 
natural habitats. The evolution of the few montane forest edge species 
also poses no problems because, although the amount of such natural 
habitat is small, one can find these species in natural forest edge 
habitats in undisturbed areas, as illustrated on p. 75. The main 
problem arises in connection with the evolution of the endemic mid- 
montane grassland populations, because the amount of natural mid- 
montane grassland (along streams, in landslide and earthquake areas) 
is minute, and because most of the endemic forms have never been 
recorded in these natural habitats in which they might be postulated 
to have evolved. Specifically, for the following 10 species with endemic 
midmontane races every midmontane record that has come to my 
attention is from a man-made habitat: Synoicus ypsilophorus, Coturnix 
chinensis, Turnix maculosa, Tyto capensis, Anthus novaeseelandiae, 
Saxicola caprata, Malurus alboscapulatus, Megalurus timoriensis, 
Lanius schach, and Lonchura spectabilis. Most of the species to which 
these endemic races belong range through the Indonesian Archipelago 
or as far as Asia and are presumably of non-Papuan origin, the ex- 
ceptions being Malurus alboscapulatus (confined to New Guinea) and 
Lonchura spectabilis (New Guinea and New Britain). ‘The only New 
Guinea midmontane grassland forms that are endemic to this habitat 


76 


FEATURES OF THE EASTERN HIGHLANDS 


at the species level are Lonchura teerinki of western New Guinea and 
Lonchura vana of the Vogelkop. ; 

‘There are two possible explanations for these cases. First, some of 
these species may have been present for a long time in the tiny amount 
of natural midmontane grassland habitat, may have evolved there into 
endemic races, and may simply not have been detected yet in such 
habitats. In other words, they would have the same history as mid- 
montane forest edge species, which had to eke out a precarious exis- 
tence before the advent of agriculture. Second, they may have evolved 
in the short time since native agriculture began to create significant 
areas of secondary midmontane grassland. Present evidence suggests 
that agriculture on a limited scale may have become possible in New 
Guinea about five millenia ago (Bulmer, 1964). However, extensive 
clearing of land began with the introduction of the sweet potato, 
which appears to have reached the Eastern Highlands only a few 
centuries ago. Thus, the time scale for evolution of the midmontane 
grassland races would be of the order of several centuries up to a few 
millenia. Until recently such a short time scale for subspeciation 
would have appeared unlikely, but the demonstration by Johnston and 
Selander (1964) of geographical differentiation in the House Sparrow 
Passer domesticus since its introduction into the New World 137 years 
ago shows that this is perfectly feasible in some cases. It is important 
to remember that population changes will occur much more rapidly 
when breeding stock is transplanted into a new type of environment 
and isolated from the parent population than in the cases of estab- 
lished populations; and, also, that severe selection pressures may 
operate on new colonists of the New Guinea midmontane grasslands, 
whether they arrive from the New Guinea lowlands or from outside 
New Guinea. 

Probably some of the 10 races listed on p. 76 have the first type of 
history, some the second. Midmontane grassland forms that surely have 
a long history include the sole two endemic species, the distinct man- 
nikin species Lonchura teerinki of western New Guinea and the semi- 
species Lonchura vana of the Vogelkop, which probably evolved in 
the marshes of the Baliem River and the Anggi Lakes, respectively. 
I would not be surprised to see the midmontane race of Malurus 
alboscapulatus eventually turn up in a marsh beside some Eastern 
Highlands stream remote from areas of human influence. At the 
other extreme, the mannikin Lonchura spectabilis gajduseki requires 
large expanses of grassland and is confined to the Karimui Basin, 
whose topography and history of human settlement are sufficiently 
well known to make it unlikely that this mannikin population could 
have existed anywhere in the Basin before the present century. 
Lonchura spectabilis gajduseki is, accordingly, a likely candidate to 
have differentiated rapidly and recently. 


FEATURES OF THE EASTERN HIGHLANDS 


Pioneering by Non-Forest Species 


When natives clear a new village and garden area in the middle of 
the forest, an island of habitat is created for grassland and second- 
growth birds, surrounded by a barrier of unsuitable forest habitat. The 
colonization of these grassland islands poses the same problems as those 
involved in the zoogeography of oceanic islands. One of my collecting 
stations, Soliabeda, was just such a non-forest island that had been 
cleared by natives a few years previously and lay several miles from the 
next such island. Consideration of the non-forest avifauna at Soliabeda 
is interesting because of its relevance to the question of what makes 
a good colonist. 

Although Soliabeda and Karimui shared most forest species in com- 
mon, Soliabeda had only part of the non-forest avifauna of Karimui. 
All four of the small aerial species of Karimui (Hemiprocne mystacea, 
Collocalia esculenta, C. hirundinacea, Artamus maximus) were present 
at Soliabeda. ‘hese species are strong fliers, and the first two would 
have been present along forest streams even before the village site was 
cleared. Of the four large aerial species of Karimui (the open country 
hawks Haliastur indus, Accipiter fasciatus, Circus approximans, Falco 
berigora), only the first was present, perhaps because the cleared area 
at Soliabeda was marginally small to provide even a single feeding 
territory. Of the 16 species in the category “open country and forest 
edge” at Karimui which also utilized the forest edge or forest interior 
(Macropygia amboinensis, Trichoglossus haematodus, Gacomantis vari- 
olosus, Dacelo gaudichaud, Eurystomus orientalis waigiouensis, Rhipi- 
dura leucothorax, Rhipidura rufiventris, Pachycephala rufwentris, 
Pitohui dichrous, Oriolus szalayi, Mino dumonti, Cracticus cassicus, 
Dicrurus hottentottus, Paradisaea raggiana, Nectarinia sericea, Meli- 
phaga auga), all except two (Eurystomus orientalis waigiouensis, 
Pachycephala rufiventris) were present at Soliabeda. Of the three 
species of “open country and forest edge” at Karimui which could not 
utilize the forest interior or forest edge (Amaurornis olivaceus, Saxi- 
cola caprata, Rhipidura leucophrys), only the rail Amaurornis oliva- 
ceus was present at Soliabeda. Of the four grassland species at Karimui 
(Synoicus ypstlophorus, Malurus alboscapulatus, Megalurus timoriensis, 
Lonchura spectabilis), only the wren-warbler Malurus alboscapulatus 
was at Soliabeda. 

Generalizing, one can say that open country species that can also 
use the forest and forest edge make the best colonists, partly because 
they can disperse most easily (through the forest or by using forest edge 
habitats along rivers as stepping stones), partly because more habitat 
is available to them for building up a stable population than to a bird 
restricted to grassland and open country. At a disadvantage are species 
with a large territory requirement, a category including not only 
hawks but perhaps also the Lonchura mannikins, which normally as- 


78 


FEATURES OF THE EASTERN HIGHLANDS 


sociate in large flocks. Of the species restricted to grassland and open 
country, the rail and the wren-warbler are apparently good colonists. 
The superior dispersal ability of the rail is in keeping with the ability 
of rails to reach the most remote oceanic islands. 


MIGRANTS 


Eleven species that breed in the palearctic region have been recorded 
from the Eastern Highlands as winter visitors, with most of the records 
between September and April. Eight of these 11 species are shorebirds 
(Charadriidae, Scolopacidae): Pluvialis dominica fulva, Numenius 
minutus, Tringa hypoleucos, Tringa brevipes, Gallinago megala, Gal- 
linago hardwicku, Calidris ruficollis, and Calidris acuminata. The 
other three are the duck Anas querquedula, the cuckoo Cuculus 
saturatus horsfieldi, and the wagtail Motacilla cinerea caspica. 

Thirteen species that breed in Australia have been recorded from 
the Eastern Highlands as winter visitors, with most of the records 
between April and October: the spoonbill Platalea regia, the falcon 
Falco cenchroides cenchroides, the pratincole Glareola isabella, the 
cuckoos Cacomantis pyrrhophanus prionurus and Chrysococcyx lucidus 
plagosus, the nightjar Ewrostopodus albogularis albogularis, the king- 
fishers Halcyon macleayu incincta and Halcyon sancta sancta, the bee- 
eater Merops ornatus, the dollarbird Eurystomus orientalis pacificus, 
the swallow Hirundo nigricans nigricans, the cuckoo-shrike Coracina 
novaehollandiae melanops, and the flycatcher Myiagra cyanoleuca. 

The most striking fact about these 24 palearctic and Australian 
migrants in New Guinea is that their distribution is strictly confined 
to open habitats, second-growth, and the forest edge. I am unaware 
of a single record of a palearctic or Australian migrant taken inside 
undisturbed forest anywhere in the Eastern Highlands. ‘There is no 
record above 9,000 ft, where there is little cleared land except natural 
alpine grassland, which the migrants evidently do not utilize. ‘The 
implication is that migrants have been coming to the Eastern High- 
lands in significant numbers only since the advent of extensive native 
agriculture, i.e., probably within the last millennium (p. 77). The 
palearctic migrants wintering in Africa similarly avoid the interior 
of the rainforest (Moreau, 1966). By contrast, wintering North Ameri- 
can species comprise a significant percentage of bird individuals inside 
the tropical rainforest of Central America. 

Because of New Guinea’s equatorial position New Guinea breeding 
species do not migrate from the island. However, there is evidence 
for local seasonal migration within New Guinea in the cases of a few 
species. Four categories may be distinguished. (1) Some species which 
breed in the lowlands may undertake postbreeding migrations to the 
Eastern Highlands. For instance, large postbreeding flocks of the 
starling Aplonis cantoroides have been recorded at Nondugl in the 


79 


FEATURES OF THE EASTERN HIGHLANDS 


Wahgi Valley. Records of the starling Aplonis metallica, of cormo- 
rants, anhingas, and herons, and possibly of some hawks (Milvus 
migrans, Circus approximans, Haliastur indus ?) may also represent 
postbreeding stragglers from the lowlands. As in the case of palearctic 
and Australian migrants, these lowland migrants are found mainly in 
cleared and second-growth areas in the Eastern Highlands. (2) Some 
species, par ticularly lories and myzomelid honeyeaters, which breed 
in the Eastern Highlands and which depend for food on transient 
sources of flowers and fruit, may undertake local seasonal migrations 
in search of food. For instance, Fore native informants told me that 
the parrots Pseudeos fuscata, Psitteuteles goldiei, and Geoffroyus 
simplex breed and are conspicuous at Okapa in the wet season, but I 
found them uncommon or absent in the dry season. The erratic dis- 
tribution of the honeyeater Myzomela adolphinae, which depends 
upon flowering trees for food, also suggests local migration. (3) The 
open country shrike Lanius schach breeds at Okapa in the dry season, 
but native informants said that it disappears during the wet season. 
Similarly, at Lake Kutubu, Schodde and Hitchcock were told by native 
informants that the open country honeyeater Philemon novaeguineae 
is absent during the wet season. ‘The cuckoo Eudynamis scolopacea 
was apparently absent from Karimui during the driest months of 
1965. (4) Some stragglers may be driven into the Eastern Highlands 
by storms, an example being the appearance of Sooty ‘Yerns, Sterna 
fuscata, at Mt. Hagen township in June 1967. 

Little or nothing is known about the details of these local migra- 
tions. Further examples of palearctic, Australian, and New Guinea 
lowland species which migrate or straggle to the Eastern Highlands 
undoubtedly will be uncovered and probably will provide most of 
the future additions to the list of species recorded from the Eastern 
Highlands. 


Birp FEEDING ASSEMBLAGES IN FRUITING AND FLOWERING TREES 


The gathering of birds of many species to feed on trees bearing 
fruit or flowers are a spectacular feature of the tropics. Several species 
of New Guinea parrots, pigeons, and honeyeaters are mainly to be 
found at these ephemeral food sources. In 1964 ‘Terborgh and I made 
a study of these feeding assemblages which has been reported in detail 
elsewhere (Terborgh and Diamond, 1970), but will be summarized 
briefly here along with some subsequent observations. 

Our method was to station ourselves at a fruiting or flowering tree 
and, at two-minute intervals, to record the number of individuals of 

each species in the tree. One individual recorded in one two-minute 
period was taken as an arbitrary unit of “bird-usage” of the tree. 
In the individual species accounts it occasionally will be stated that a 
given species accounted for a certain percentage of the bird-usage 


80 


FEATURES OF THE EASTERN HIGHLANDS 


of a particular tree; this refers to the bird-usage units of that species 
as a percentage of the total bird-usage units of all species in that tree. 

Usage of flowering trees was dominated by honeyeaters (notably of 
the genera Oedistoma, Myzomela, and Meliphaga) and by lorikeets 
(Chalcopsitta, Pseudeos, Trichoglossus, Domicella, Charmosyna, Oreo- 
psittacus, and Neopsittacus). ‘Ten to 16 species were regularly seen in 
one tree. Most of these species presumably were obtaining nectar and 
insects from the flowers, but the parrot Trichoglossus haematodus ate 
the flower receptacles as well. At a given locality essentially the same 
eroup of bird species reappeared in different species of flowering trees. 
Within a given tree there was some vertical segregation of the honey- 
eaters, with Oedistoma pygmaeum and the several species of Myzomela 
mainly in the canopy and the species of Meliphaga mainly in the lower 
branches. While the honeyeaters moved in and out as individuals, the 
lorikeets often arrived and departed as flocks. Several of the lories 
have crimson upperparts, and of those which have green upperparts, 
several have a crimson or blue rump. ‘This striking dorsal coloration 
must make them conspicuous when viewed from above against the 
green jungle, and may serve to attract the attention of other members 
of the species to a flock flying towards a tree which it has located. 

Trees bearing small fruits (up to 5 mm in diameter) were utilized 
by representatives of more bird families (Columbidae, Campephagidae, 
Pachycephalinae, Sturnidae, Paradisaeidae, Meliphagidae, Dicaeidae, 
a few Psittacidae) than were flowering trees. Nine to 16 species were 
regularly seen in one tree. Trees with larger fruits (greater than 10 mm 
in diameter) were virtually monopolized by pigeons, particularly those 
of the genus Ptilinopus. Ficus trees with large fruits several inches in 
diameter surrounded by a woody rind were monopolized initially by 
parrots (Trichoglossus haematodus, Psittaculirostris desmarestit), which 
chipped holes in the rind with their strong bills. Later, members of 
other families, particularly Campephagidae, Paradisaeidae, and long- 
billed species of Meliphagidae, inserted their weak bills into the hole 
to obtain pulp which the shorter-billed parrots had been unable to 
reach. 

These transient assemblages of birds that gather in fruiting or 
flowering trees should not be confused with the mixed-species, itinerant, 
mainly insectivorous flocks which forage through tropical forests in 
many parts of the world. It is worth mentioning explicitly that I never 
encountered such itinerant flocks in the Eastern Highlands. Further- 
more, when I brought four of my Eastern Highlands assistants with 
me to the North Coastal Range in 1966 and we met itinerant flocks 
for the first time, they related to me their amazement and were 
emphatic that their own birds at home didn’t behave that way! In 
contrast, Gilliard (in Gilliard and LeCroy, 1968) observed mixed 
flocks in the Schrader Range of the Eastern Highlands; Schodde and 
Hitchcock (1968, p. 40) mentioned their presence at Lake Kutubu; 


81 


FEATURES OF THE EASTERN HIGHLANDS 


Rand (Mayr and Rand, 1937, pp» 114, 192, 159; 161; Anehibold, Rand 
and Brass, 1942, p. 246) encountered them in western New Guinea 
and southeastern New Guinea; and I found them on Mt. Albert- 
Edward, and at certain localities and altitudes but not at others in the 
North Coastal Range. I have no explanation for this apparent un- 
predictability. 


RAINFALL 


Rainfall patterns in the Eastern Highlands are relevant to the 
problem of bird breeding seasons discussed in the next section. 

Tables 2 and 3 give rainfall records for Okapa Patrol Post and for 
Karimui Patrol Post, respectively, kindly supplied by the patrol officers 
at these stations. Rainfall records for some other stations, including 
Lufa and Goroka, have been published by Brass (1964), and records 
for the Kubor Range and Lake Kutubu have been summarized by 
Hitchcock (1964) and by Schodde and Hitchcock (1968). 

For much of the Eastern Highlands the annual rainfall averages 
between 70 and 180 inches, and there is a weakly differentiated dry 
season between May and September and rainy season between Novem- 
ber and April. However, the distinctness of wet and dry seasons varies 
from year to year and varies among neighboring localities in the same 
year. 

At Okapa the annual rainfall averages 91 inches and varies in dif- 
ferent years between 65 and 136 inches. ‘he wettest month, March, has 
on the average 3.4 times as much rain as the driest month, June. In at 
least five of the eight years up to 1965 for which there are records, 
May, June, July, August, and September were drier than the average 
month of that year, and December, February, March and April were 
wetter than the average month. ‘The June-July dry season was quite 
pronounced in 1956, 1964, and 1965. However, normally dry September 
was the wettest month in 1963, and May was the third wettest month 
in 1962, while normally wet February was the third driest month in 
1963 (drier than June-October) and December was the third driest 
month in 1964. 

At Karimui the pattern is qualitatively similar but wetter overall 
and less distinct. Annual rainfall averages 131 inches and varies from 
113 to 158 inches, with January, February, March, April, and Septem- 
ber on the average the wettest months and June, July, August, and 
November the driest months. ‘The June-August dry season was fairly 
pronounced in 1964, and more pronounced in 1965. However, the 
wettest month, March, has on the average only 2.3 times as much 
rain as the driest month, June. In 1961 normally dry July was the 
wettest month. These statements are based on rainfall records taken 
at Karimui Patrol Post. The situation on Mt. Karimui, for which no 
records are available, is patently different. The mountain is usually

shrouded in cloud even when it is fair at Karimui Patrol Post. I was 
told after descending from Mt. Karimui in August 1965 that the 
month I spent on the mountain had been the driest period on record 
since a rain gauge was set up at Karimui Patrol Post. On Mt. Karimui 
this irreducible minimum of precipitation meant that it rained day 
and night without interruption for half of the days on the mountain, 
and only seven of the days we spent on it were without any rain. 

At Lake Kutubu (Schodde and Hitchcock, 1968) May to October 
is the wettest season, rather than the driest season as in the Wahgi 
Valley and my study areas. 

‘To summarize, during the particular months and years of my studies 
(June-September 1964 and 1965) the particular localities I visited were 
experiencing a relatively dry season. This would have been true in 
these months at these localities in most but not all other years, and at 
many other but not all localities in the same years. 


BREEDING SEASONS IN THE EASTERN HIGHLANDS 


Breeding patterns in the Eastern Highlands are complex in that 
they differ among birds of different habitats, vertical strata, altitudes, 
or food habits. Hence, analysis of breeding activity in separate seg- 
ments of the avifauna is more informative than analysis of the avi- 
fauna as a whole. The following categories, which overlap to some 
extent, will be considered: grassland birds; birds of second-growth and 
the forest edge; hawks; birds that frequent fruiting trees; birds that 
frequent flowering trees; meliphagids generally; forest birds of the 
ground and lowerstory; forest warblers; other forest species. Since my 
records are most detailed for the Karimui area (Karimui, Bomai, 
Soliabeda, Mt. Karimui), all remarks refer to this area unless it is 
specifically stated otherwise. Breeding patterns on Mt. Karimui dif- 
fered from those at lower elevations and will be cited separately, but 
those from the three stations at lower elevations (Karimui, Bomai, 
Soliabeda) were similar to each other and will be referred to without 
distinction simply as the pattern at Karimui. Most information is 
based on examination of gonad size, but some is derived from actual 
nests or nestlings. It will be recalled that this information comes from 
the relatively dry months of June, July, and August of 1964 and 1965. 
Although several patterns emerge from my results, they must be con- 
sidered preliminary for three reasons: (a) they are based on extrapola- 
tion from a fraction of the year; (b) a condition of enlarged testis size 
may be maintained for longer than the actual nesting seasons; and 
(c) I have no information on peak seasons of fruit, flower, seed, and 
insect production. 

Grassland birds——Adequate information to judge breeding condi- 
tion was obtained at Karimui for three species that live in grassland: 
the rail Amaurornis olivaceus, the wren-warbler Malurus alboscapu- 


84 


FEATURES OF THE EASTERN HIGHLANDS 


latus, and the mannikin Lonchura spectabilis. All adults collected of 
all three species had gonads in breeding condition, and nestlings of 
all three species were obtained. ‘Thus, there was a highly synchronous 
breeding peak in the dry season. In addition, the cuckoo Cacomantts 
variolosus, which lives in garden trees rather than in the grass itself 
but uses Malurus abolscapulatus as its principal foster parent, was 
breeding. Information was obtained for more grassland species at 
Okapa, and all were breeding: Malurus alboscapulatus and Lonchura 
spectabilis, plus the quail Synoicus ypsilophorus, the rail Porzana 
tabuensis, the grass-warbler Megalurus timoriensis, and the shrike 
Lanius schach. Lanius schach actually appears to leave the Okapa re- 
gion in wet seasons. 

Birds of second-growth, the forest edge, and open spaces (excepting 
hawks).—All adults taken at Karimui of 11 species in this category 
were found not to be in breeding condition: the crested swift Hemi- 
procne mystacea, the swifts Collocalia hirundinacea and C. esculenta, 
the kingfisher Dacelo gaudichaud, the dollarbird Eurystomus orien- 
talis, the flycatchers Peltops blainvillii and P. montanus, the oriole 
Oriolus szalayi, the drongo Dicrurus hottentottus, the starling Mino 
dumontii, and the sunbird Nectarinia sericea. Some but not all adults 
of the flycatchers Rhipidura leucothorax and Pachycephala rufiventris 
and the butcherbird Cracticus cassicus were breeding. ‘here was some 
breeding in the wood swallow Artamus maximus, and most individuals 
of the honeyeater Meliphaga auga were breeding, in 1964, but there 
was no breeding in either species in 1965, which was drier. Evidently 
breeding of most forest edge species ceases completely when it becomes 
sufficiently dry. The situation is thus exactly opposite to the case of 
grassland birds. 

Hawks.—No individual in breeding condition was encountered 
among the six species of hawks whose gonads were examined (Accipi- 
ter novaehollandiae and Falco berigora, in open country; Aviceda sub- 
cristata, Accipiter poliocephalus, and Megatriorchis doriae, in lowland 
forest; and Accipiter melanochlamys, in montane forest). 

Frugivores (except meliphagids)—Under this category are lumped 
42 forest species that feed to a large extent on fruit: all species of 
arboreal pigeons about which evidence was obtained, totaling 12; the 
parrot Psittaculirostris desmarestit; the hornbill Aceros plicatus; all 
species of campephagids, totaling seven; the whistler Pachycephala 
leucostigma; all species of birds of paradise and bowerbirds, 14 in all; 
and all dicaeids, six in all. Of the 29 frugivores at Karimui, there were 
19 species in which all individuals were uniformly in nonbreeding con- 
dition; five species in which some individuals were breeding in 1964 
but none in 1965 (the pigeon Ducula zoeae, the parrot Psittaculirostris 
desmarestii, the birds of paradise Manucodia chalybatus and Lopho- 
rina (Diphyllodes) magnifica, and the bowerbird Ailuroedus buc- 
coides); two species in which some but not all individuals were breed- 


85 


FEATURES OF THE EASTERN HIGHLANDS 


ing in 1965 (the bird of paradise Lophorina (Ptiloris) magnifica and 
the flowerpecker Dicaeum geelvinkianum); one species which was not 
breeding in July and August 1965 but entered breeding condition in 
September 1965 (the pigeon Megaloprepia magnifica); and two species 
in which virtually all individuals were breeding (the pigeon Ptilinopus 
superbus and the bird of paradise Lophorina (Cicinnurus) regia). The 
situation was quite different on Mt. Karimui: out of 15 frugivores, 
only five species showed no signs of breeding, while in ten species 
some (but generally not all) individuals were breeding. In the case of 
two species, the pigeon Macropygia nigrirostris and the bird of para- 
dise Lophorina (Diphyllodes) magnifica, present both on Mt. Karimui 
and in the Karimui Basin, the montane population was breeding, but 
the lowland population was not, although numerous adults were 
present. 

‘The simplest interpretation to cover most of these facts is that breed- 
ing is almost entirely confined to times of local wet conditions in most 
fruit-eating birds. ‘The systematic difference between Mt. Karimui and 
the lower elevations is to be expected from the fact that conditions 
were considerably drier at the lower elevations during my studies. ‘The 
fewer breeding records from 1965 than 1964 reflect the differences in 
rainfall. 

Birds that depend wpon flowering trees—Thirteen species feed 
mainly or almost exclusively in flowering trees: seven parrots of the 
subfamily Loriinae, and six honeyeaters (Oedistoma iliolophum, O. 
pygmaeum, and four species of Myzomela). Of the nine species at 
Karimui, five were not breeding, one (Trichoglossus haematodus) was 
breeding in 1964 but not 1965, and some but not all individuals were 
breeding in three cases (Charmosyna placentis, Myzomela cruentata, 
Oedistoma iliolophum). Of the four species on Mt. Karimui, two 
(Oreopsittacus arfaki and Myzomela rosenbergit) were breeding, and 
two (Charmosyna papou and C. pulchella) were not. At Okapa natives 
and Europeans said that the several species of lories there had young 
in the wet months from November on. 

Honeyeaters (Meliphagidae).—There are 18 additional species of 
meliphagids which are not so strikingly tied to flowering trees, though 
most visit flowering and/or fruiting trees. Of the 12 species at Karimui, 
eight were uniformly not breeding, two were represented by some 
breeders in 1964 but none in 1965, and two had breeding individuals 
in both 1964 and 1965 but fewer in 1965. ‘Thus, breeding is sup- 
pressed partly or completely in all these species in a dry spell. In the 
wetter conditions on Mt. Karimui only one species (Meliphaga orien- 
talis) was uniformly nonbreeding, four species had some or most in- 
dividuals breeding, and in two species (Melidectes rufocrissalis and 
Ptiloprora guisei) all males had greatly enlarged testes. 

Forest birds of the ground and lowerstory.—This category consists 
of nine forest species that feed on the ground (four pigeons of the 


86 


FEATURES OF THE EASTERN HIGHLANDS 


genera Chalcophaps, Henicophaps, and Gallicolumba, the pitta Pitta 
erythrogaster, the thrushes Amalocichla incerta and Drymodes super- 
ciliaris, and two logrunners of the genus Eupetes), plus 18 forest war- 
blers, flycatchers, whistlers, and honeyeaters which forage largely or 
exclusively in the lower story. At Karimui many, but not all, individ- 
uals of eight species were breeding, virtually all individuals of one (the 
flycatcher Poecilodryas placens) were breeding, three species had some 
breeding individuals in 1964 but not in 1965, and three were not 
breeding. On Mt. Karimui there were breeding individuals of six 
species but none of eight species. In two of these six species (the war- 
bler Sericornis nowhuysi and the flycatcher Peneothello cyanus) all or 
most individuals were breeding. ‘wo species present both on Mt. 
Karimui and at lower elevations (the warbler Crateroscelis murina 
and the whistler Collwricincla megarhyncha) had breeding individuals 
at low elevations but not on the mountain. ‘Thus, the pattern in forest 
lowerstory birds is the opposite of the pattern among arboreal fruit 
eaters, in that there is more breeding activity at Karimui than at 
higher elevations. Evidently there is some tendency in lowerstory birds 
to nest in the dry season, and more were therefore nesting at Karimui, 
where the dry period was more pronounced. 

Forest warblers.—Eleven species of forest warblers occur at Karimui 
or on Mt. Karimui (Clytomyias insignis, five species of Sericornis, two 
species of Crateroscelis, and three species of Gerygone). Most, but not 
all, individuals of four species were in breeding condition, all indi- 
viduals of five species were breeding, Clytomyias insignis was not 
breeding, and Crateroscelis murina was breeding at Karimui but not 
on Mt. Karimui. ‘T'wo of these 11 species (Crateroscelis) were confined 
to the lowerstory, while most of the others are often but not exclu- 
sively found in the lowerstory. ‘This might suggest that the breeding 
of warblers is just another expression of the tendency of lowerstory 
species to be breeding in June-August. However, the warbler Gery- 
gone palpebrosa, which I have never seen in the lowerstory, was breed- 
ing at Karimui; and six out of the eight warblers on Mt. Karimui 
were breeding, although the majority of lowerstory species generally 
on Mt. Karimui were not breeding. ‘Thus, lowerstory habits are not 
necessarily the explanation for breeding patterns in forest warblers. 

Other forest species——Among forest flycatchers (Muscicapinae and 
Pachycephalinae) not confined to the lower story, breeding individuals 
were encountered among seven of 14 species at Karimui and among 
three of 10 species at Mt. Karimui. In only two cases (Microeca flavo- 
virescens at Karimui, and Tregellasia leucops on Mt. Karimui) was 
there evidence that the whole adult population had come uniformly 
into breeding condition. Finally, one may consider a “wastebasket” 
category consisting of all forest species not belonging to the categories 
considered so far—three parrots, five cuckoos, four nocturnal species, 
three kingfishers, one logrunner, one drongo, one crow, and one man- 





87 


FEATURES OF THE EASTERN HIGHLANDS 


nikin. Only two of the 15 species at Karimui in this “wastebasket” 
category were breeding, and only two of six on Mt. Karimui. 

Summary of breeding patterns.—During the dry months of July- 
August 1964 and 1965 at Karimui, breeding was taking place among 
all grassland birds, most lowerstory forest birds, and most warblers, 
but was not occurring among most second-growth birds, frugivores, 
flower feeders, meliphagids, or most other middlestory and upperstory 
forest species. On Mt. Karimui during these same months, where con- 
ditions were wetter, breeding was taking place among most frugivores, 
meliphagids, and warblers, but not among most other species. “Breed- 
ing’ in these statements is taken to mean that a significant fraction 
of individuals of a given species were in breeding condition. 

In addition, it is worth considering in which species there appeared 
to be a highly synchronized pattern, such that virtually all individuals 
either were or were not breeding. Synchronous breeding peaks were 
found among all species of grassland birds, two frugivores at Karimui, 
three meliphagids on Mt. Karimui, one lowerstory species at Karimui 
and two on Mt. Karimui, two warblers at Karimui and three on Mt. 
Karimui, and one flycatcher at Karimui and one on Mt. Karimui. 
Breeding was completely suppressed in all hawks, most second-growth 
species, most frugivores, flower feeders, and meliphagids at Karimui, 
and many other forest species of the middle- and upperstories. 

‘There were three species (the pigeon Ptilinopus superbus, the war- 
bler Sericornis papuensis, and the honeyeater Myzomela rosenbergit) 
of which most or all specimens collected proved to be males, all in 
breeding condition. All nine specimens collected of the pigeon Ptili- 
nopus pulchellus proved to be males and all were not breeding. Only 
males of the swiftlet Collocalia hirundinacea were collected in early 
July, only females in late July. ‘The explanation for these unbalanced 
sex ratios is unclear. 

For comparison with the Karimui results, incidental information 
about breeding patterns has been obtained in four other parts of New 
Guinea. ‘The peak breeding months for most species are September- 
November in the Wharton Range of southeastern New Guinea (Mayr 
and Rand, 1937; Schodde, cited in Schodde and Hitchcock, 1968, p. 17; 
my experience on Mt. Albert-Edward), November-March in northwest- 
ern New Guinea (Rand, 1942b; Ripley (1964), however, reports May- 
October), October-January in the western Papuan islands (Ripley, 
1964), and September-October at Lake Kutubu (Schodde and Hitch- 
cock, 1968). These peaks fall in the austral spring and summer. At these 
localities, as at Karimui, the rainy season is November to April and 
the dry season June to August, except at Lake Kutubu, where May- 
October are the wettest months. 

Factors related to breeding patterns —Rainfall patterns probably 
have a significant effect on breeding, with dry weather suppressing 
breeding in most species but eliciting synchronized breeding peaks in 


88 


FEATURES OF THE EASTERN HIGHLANDS 


grassland and forest understory or ground-dwelling birds. ‘The sup- 
pressing effect of very dry weather is illustrated by a comparison of 
the 1964-1965 results. The following ten species were in breeding con- 
dition at Karimui in July-August 1964 (July 30 to August 17) but 
were not breeding (although resident) in the much drier months July- 
August 1965 (July 1 to August 6): Trichoglossus haematodus, Psittac- 
ulirostris desmarestii, Monarcha guttula, Pachycephalopsis poliosoma, 
Artamus maximus, Manucodia chalybatus, Lophorina (Diphyllodes) 
magnifica, Ailuroedus buccoides, Meliphaga flaviventer, and Meli- 
phaga auga. In the cases of four additional species, breeding occurred 
in July-August of both years, but the percentage of the local popula- 
tion breeding was considerably higher in 1964: Ducula zoeae, Colluri- 
cincla megarhyncha, Toxorhamphus poliopterus, and Melilestes me- 
garhynchus. Similarly, a suspension of breeding by some bird species 
in the dry season and a sudden resumption with the onset of rains has 
been described in Trinidad by Snow and Snow (1964) and in Vene- 
zuela by Gilliard (1959a). 

Grassland birds evidently reverse the normal trend, wait for a dry 
spell, and then come into breeding condition rapidly and synchro- 
nously. A possible explanation is that nests in grassland, whether on 
the ground or in grass, receive nearly the full force of a downpour and 
are more susceptible to damage by rain than are nests in trees or the 
forest. Similar considerations may apply to ground-dwelling forest 
species. An analogy is provided by the duck Salvadorina waigiuensis, 
which breeds in the Karimui area at the height of the dry season: it 
nests on low boulders beside streams subject to flash floods after heavy 
rains in the foothills, and such nests would have little chance of success 
in wet periods. 

It is interesting that the peak breeding season is the austral spring 
and summer (October-March) in New Guinea and at most southern 
hemisphere tropical as well as temperate localities, even within a few 
degrees of the equator, while the peak breeding season at tropical as 
well as temperate localities north of the equator is generally in the 
boreal spring and summer, March-June (Moreau, 1966; Snow and 
Snow, 1964). Part of the reason may be that the months of peak rain 
correspondingly reverse near the equator. However, local rainfall pat- 
terns may not be the sole determinant of breeding, since peak breed- 
ing still occurs in the austral spring at Lake Kutubu even though the 
rainfall pattern is locally reversed there, the spring being the end of 
the rainy season rather than the beginning, as in much of the rest of 
New Guinea. In the New World, Snow and Snow (1964, p. 32) tenta- 
tively interpret a similar situation to mean that “natural selection 
has led to complexes of closely knit seasonal changes, affecting both 
animal and plant life, which may prevail over large areas and be 
adapted to the general climatic conditions of the region but not per- 
fectly adapted to special local conditions.” 


89 


FEATURES OF THE EASTERN HIGHLANDS 


Factors which one might a priori postulate to integrate breeding 
seasons over large areas at the same latitude despite local differences 
in rainfall patterns include the annual cycles of daylength, light in- 
tensity, and temperature. Another consideration is whether resident 
birds time their breeding to avoid competition from the influx of 
wintering and postbreeding birds from Australia, the palearctic zone, 
and the New Guinea lowlands. As discussed on p. 00, these visitors 
are strictly confined to open habitats and seem unlikely to influence 
the breeding of forest species. Only four resident species of open coun- 
try in the Eastern Highlands appear to face an influx of conspecific 
or congeneric Australian or palearctic visitors: citing the resident first 
and the vistor second, these are the falcons Falco berigora novae- 
guineae and F. cenchroides cenchroides, the cuckoos Cacomantis pyr- 
rhophanus excitus and C. p. prionurus, the dollarbirds Eurystomus 
orientalis waigiouensis and E. 0. pacificus, and the swallows Hirundo 
tahitica frontalis and H. nigricans nigricans. All four of these visiting 
species are uncommon or local in the Eastern Highlands. The resident 
Eurystomus and Falco were not breeding during the season of the 
visitors’ presence in my study areas, while I have no information con- 
cerning the breeding season in the other two cases. 

Further progress in understanding breeding seasons of New Guinea 
birds will require information about seasonal variations in food abun- 
dance, combined with year-round records of bird cycles based on nests 
and juveniles rather than on gonad condition. 


NATIVE CLASSIFICATIONS AND KNOWLEDGE OF BIRDS 


My introduction to the systems of zoological classification developed 
by New Guinea natives came during the first week of my first season in 
the Eastern Highlands, when I was staying at the Fore village of 
Miarosa and was trying to learn some words of the Fore language. As 
I was washing at the village spring one evening and a frog began 
calling nearby, a small Fore boy explained, “Dakwo wanipindi min- 
die.” I had already learned that “wanipindi” was the word for “water” 
in the locative case, and that “mindie’’ was the form of the verb “to 
be” used for living things, so that I assumed that the sentence meant 
“There’s a frog in the water” and that “dakwo” meant “frog.” The 
next day a man caught and brought me a frog while we were in the 
forest, and I pointed to it and said “dakwo” to practice the new word. 
“No, no,” I was told, “This isn’t dakwo. Dakwo is another fellow. 
This one is ibisaraya.”” Evidently different species of frogs had different 
names. 

Thereafter I made a systematic effort to learn Fore names for ani- 
mals, by asking individual natives to identify collected specimens, to 
name bird calls we heard, to name birds we saw in the field, and to 
describe animals they knew about but had not yet been able to show 


90 


FEATURES OF THE EASTERN HIGHLANDS 


me. In this way I obtained Fore names and identifications or descrip- 
tions of 110 birds, 15 small mammals, 20 large mammals, 16 frogs, 
and 17 lizards and snakes. These names have been discussed elsewhere 
(Diamond, 1966). Detailed analyses of zoological classification by the 
Karam people of the Schrader Range have been published by Bulmer 
(1967a, 1968) and Bulmer and ‘Tyler (1968). I made no attempt to 
get names for plants but am sure that these were also classified, since 
Paran and Esa responded to an idle remark I once made about mush- 
rooms with a long lecture naming and describing 31 kinds of mush- 
rooms in the vicinity of Awande, whether each was edible, and on 
what each was likely to be found growing. 

It turned out that the Fore had a name for every bird that occurred 
regularly in the area. Usually each species had a separate name, and 
even sibling species as similar as two Sericornis warblers or the two 
Macropygia cuckoo-doves were distinguished. In a few cases (Gery- 
gone warblers, Halcyon kingfishers, Melanocharis berrypeckers) related 
species were lumped under the same name but might then be distin- 
guished by an added epithet. For instance, the kingfisher Halcyon 
sancta was named “‘patoroba bilong place” (the “patéroba” of settled 
areas), while Halcyon megarhyncha was “‘patoroba bilong bush” (the 
“patoroba” of the forest). In the cases of some birds of paradise and 
bowerbirds with marked sexual dimorphism, such as Lophorina su- 
perba and Amblyornis macgregoriae, the name for the adult male 
differed from that for the female or immature male. 

‘Towards the end of my first season, Paran, my best Fore informant 
at Awande village, gave me names and descriptions of 30 birds which 
he knew but which I had not yet collected. All of these were eventually 
identified tentatively or definitely in 1965 and 1966. Many of the birds 
he described were not only rare but small and undistinctive (e.g., 
Crateroscelis nigrorufa or the “fuintara”, Cisticola exilis or the “ikonan- 
tube”, Clytomyias insignis or the “tabugiri’). Some of the birds he 
discussed had been seen only once or twice in recent memory at 
Awande. For instance, Paran had seen the “da” (Talegalla sp.) only 
twice; the “topa” (apparently a white heron) had last been seen in 
1964, when one individual appeared at Awande; and no one had seen 
the “kwi-kwipa” (Gallinula tenebrosa or Porphyrio porphyrio) since 
one had been captured 10 years earlier during Paran’s boyhood. These 
names and descriptions proved useful in tracking down missing species. 
Correspondingly, Fore knowledge of local birds was sufficiently ex- 
haustive that in cases where I showed the Fore a specimen of a bird 
and they stated that it did not occur at Awande, I feel that this infor- 
mation can be relied upon. 

The purpose behind Fore animal names appears to be utilitarian. 
The only large animals to serve as sources of meat are the pig, the 
cassowary, and (formerly) man, so that even the smallest birds are 
hunted and eaten, as are mice, lizards, bats, and beetles. In addition, 


91 


FEATURES OF THE EASTERN HIGHLANDS 


the feathers of many birds (birds of paradise, bowerbirds, and some 
parrots and hawks) are prized for decoration. As a result, many Fore, 
particularly boys and men, possess an incredibly detailed knowledge 
of the habits and voices of birds and other animals in their area. It 
should be realized that Fore natives vary individually in their knowl- 
edge, reliability, and powers of observation, just as do Europeans. 
Some of the younger generation of Fore, who are going to schools, 
have acquired little knowledge of the local fauna. It should also be 
realized that linguistic difficulties, misunderstandings, and inadequate 
interviewing techniques can easily result in wrong information when 
one is quizzing natives. Information elicited from primitive peoples 
is systematically discounted by some ornithologists who have found 
such information unreliable in their experience, as a result of work- 
ing with poorly informed groups or poorly informed individuals, or 
employing inadequate interviewing techniques. However, an undif- 
ferentiated rejection or acceptance of all information supplied by 
natives is no more justifiable than would be the undifferentiated re- 
jection or acceptance of all information supplied by professional orni- 
thologists. Some observations on bird distribution, behavior, or song 
by Paran and several of my other New Guinea associates will be dis- 
cussed in this monograph under the species accounts, because I found 
these individuals equal to the best European observers I have known 
in their powers of species recognition, knowledge of birds, and care 
in separating fact from opinion or hearsay. 

‘The species accounts in the remainder of this book give the Fore 
name for each bird wherever identified with certainty. In some cases 
the names in the North Fore dialect spoken at Awande and the South 
Fore dialect spoken at Miarosa differ and are given separately. I have 
also listed some names obtained from my Gimi assistants. The Gimi 
and Fore languages are related but mutually unintelligible, and Gimi 
and Fore names occasionally coincide but usually differ. Finally, I 
have given the Daribi names given by my assistants from the Karimui 
basin. Iwo supposedly unrelated languages, Daribi and ‘Tudawhe, are 
spoken at Karimui, and comparison of lists of names from a Daribi 
village (Bomai), a Tudawhe village (Soliabeda), and a border village 
(Yudo) shows that there have been some word borrowings, so that some 
Daribi names I cite may actually be derived from ‘Tudawhe. Many 
more species of birds occur at Kari imui than at Awande, and I found 
that the Daribi apply the same name to several related birds more 
often than do the Fore. 


SUMMARY 


1. Paichiness of distribution—The distribution of some bird spe- 
cies on the Central Range is discontinuous, in that they are absent 
from the Eastern Highlands but present on other parts of the chain 


92 


FEATURES OF THE EASTERN HIGHLANDS 


farther west and farther east. Numerous intermediate cases show that 
speciation in the mountains of New Guinea usually involves the for- 
mation of western and eastern isolates on the Central Range, which 
then reinvade each other's ranges. The formation of such isolates on 
a continuous mountain chain is made possible by distributional dis- 
continuities resulting from local extinctions. ‘This distributional patch- 
iness in New Guinea forest birds is probably due to low dispersal 
rates and high species diversity, and also expresses itself in differences 
between the avifaunas of nearby mountains and in fragmented, relict- 
like distributions of some species. 

2. Ecological sorting mechanims.—Completed speciation requires 
not only the development of reproductive isolation but also of eco- 
logical segregation. ‘The principal ecological sorting mechanism among 
congeners in the mountains of New Guinea, and usually the first one 
to develop, is altitudinal, such that two to five bird species replace 
each other abruptly with altitude. ‘he sharpness of these transitions 
is due to competition, as shown by compression of altitudinal ranges 
during speciation and reinvasion and by expansion when one species 
is locally eliminated. Congeners may also sort out spatially by occupy- 
ing different habitat types; by foraging at different vertical levels in 
the vegetational column; by allopatry; and by “checkerboard allo- 
patry.’”” Nonspatial sorting related to food and foraging differences 
frequently depends upon a difference in body size. ‘The ratio of body 
weights of two congeners which sort out by size averages 1.90 and 
usually falls between 1.5 and 2.5, due to a balance of selective pres- 
sures. Instances of temporal segregation are rare in New Guinea. 

3. Zoogeography—The Central Range may be divided into three 
weakly defined regions, based on presence of endemic forms and ab- 
sences of otherwise widespread forms. Most geographic variation in 
montane birds on the Central Range is east-to-west and results simply 
from distance. In birds confined to elevations below 5,000 ft variation 
is mainly north-south because of the barrier posed by the Central 
Range. 

4. Avifauna of the Karimui Basin—Karimui, a flat mountain- 
ringed basin at 3,500 ft, has an avifauna typical of the sea level low- 
lands rather than of the hill slopes. Several lowlands birds isolated in 
this tropical “island” within the highlands have differentiated to yield 
melanistic endemic forms. 

5. Altitudinal distribution.—Analysis of the altitudinal ranges of 
166 forest bird species on Mt. Karimui, derived from altitudinal cen- 
suses along the west ridge from 1,350 ft to the summit at 8,165 ft, 
shows that species diversity decreases with increasing altitude; and 
that definition of altitudinal montane “zones” of bird distribution 
would be arbitrary, since species turnover is a fairly smooth function 
of altitude except for the local anomalies introduced by the flat floor 
of the Karimui Basin. The population structure of most species 





93 


FEATURES OF THE EASTERN HIGHLANDS 


changes in a characteristic way with altitude: at the bottom of the 
altitudinal range are immatures, nonbreeding adults appear somewhat 
higher, breeding adults still higher, and another band of immatures 
may exist at the upper limit of the altitudinal range. This population 
structure 1s present to an exaggerated degree in birds of paradise. 

6. The breeding nonforest avifauna—tIn the mountains of New 
Guinea the breeding nonforest avifauna is limited in variety because 
there is little natural nonforest habitat in the mountains. Some of 
these nonforest species evolved in specialized habitats, at the forest 
edge, or in forest; others have recently begun to spread upward from 
the lowlands as native agriculture creates increasing expanses of open 
country; and still others may have differentiated rapidly and recently. 

7. Migrants.—Palearctic and Australian wintering migrants to the 
Eastern Highlands are absolutely confined to nonforest habitats. ‘There 
are a few cases of local migration of New Guinea species in the Eastern 
Highlands, involving postbreeding lowlands birds, species depending 
upon fruiting and flowering trees, and species escaping wet or dry 
conditions. 

8. Patterns of breeding activity.—In the Eastern Highlands the pat- 
terns of breeding activity are very complex and vary among different 
groups of birds, at different localities, at different elevations, and in 
different years. In general, grassland species have a highly synchro- 
nized breeding peak in the dry season; birds of second-growth, meliph- 
agids, and other species dependent upon fruiting and flowering trees 
tend to breed in the wet season; and lowerstory birds and warblers 
tend to breed in the dry season. 

9. Assemblages in fruiting and flowering trees, rainfall, and native 
classification.—Bird feeding assemblages in fruiting and flowering 
trees, rainfall patterns, and classifications of birds by New Guinea 
natives are summarized.

Measurements and weights——All measurements are given in milli- 
meters, and all weights in grams. Wing measurements are of the wing 
straightened against a ruler, while tail measurements are from the in- 
sertion of the central pair of rectrices to the tip of the longest rectrix. 
In cases of large series I omit individual values and cite instead the 
range, average value, and standard deviation in the form illustrated 
by the example “8 4: 15.2-19.4 (17.4 + 1.2),” where 15.2-19.4 is the 
range, 17.4 the average value, and 1.2 the standard deviation. In the 
lists of specimens, a number followed by a question mark (e.g., “2 ¢, 
1 9, 1imm. 4, 1 ?”) always means that the sex was not determined 
and does not mean that the species identification is in question. 

Specimens examined.—Under “specimens examined” I list not only 
birds prepared and brought back as skins, skeletons, or in for- 
malin, but also a large number of birds examined and often mea- 
sured, weighed, and sexed in the field but not retained as specimens. 
This latter category includes some specimens collected and offered for 
sale by local natives, and some mistnetted birds that were subsequently 
released, and consists principally of individuals of excessively common 
species and of protected species. 

Localities —The names and elevations of my collecting localities 
may be summarized again here for convenient reference. Okapa area: 
Awande (6,000 ft), Miarosa (5,800 ft), Okasa (3,550-4,250 ft). Mt. M1- 
chael area: Lufa (6,300 ft), Mt. Michael (7,000-12,300 ft), Mengino 
(4,600-6,150 ft). Karimui area: Karimui (3,650 ft), Bomai (3,250 ft), 
Soliabeda (1,350-2,000 ft), Sena River (4,500 ft); Mt. Karimui Zone 1 
(4,000-4,200 ft), Zone 2 (4,400-4,750 ft), Zone 3 (4,750-5,390 ft), Zone 4 
(5,390-5,960 ft), Zone 5 (5,960-6,500 ft), Zone 6 (6,500-7,080 ft), Zone 7 
(7,080-7,620 ft), Zone 8 (7,620-8,165 ft). 

Stomach contents, voice, and abundance.—Because I did not exam- 
ine stomach contents of my Eastern Highlands specimens, the stomach 
contents analyses reported in the text are all from specimens I col- 
lected on Mt. Albert-Edward in southeastern New Guinea in 1969. 
All other remarks about specimens, behavior, and voice are based on 
the Eastern Highlands unless specifically stated otherwise. 

Figures 10-15, 17-35, and 37-42 depict vocalizations in simplified, 
diagrammatic fashion by representing relative pitch vertically and rel- 
ative duration horizontally, with syllables and sound quality specified 
in some cases. 

Estimates of relative abundances, obtained by the method described 
on p. 10, are frequently stated, using the expression “At locality X, 


species Y accounted for Z°%, of the local avifauna.”

Laxonomy and nomenclature. Scientific nomenclature in general 
follows that used by Rand and Gilliard (1967) in their Handbook of 
New Guinea Birds. Most of the deviations involve overdue or gen- 
erally accepted lumping of monotypic or small genera. 

Most vernacular names follow the current practice of the New 
Guinea Bird Society, viz., to use current Australian names (An Index 
of Australian Bird Names, CSIRO Division of Wildlife Research, 
‘Technical Paper No. 20, 1969) for those New Guinea birds also found 
in Australia, and to use names proposed by Rand and Gilliard (1967) 
for other species. For species of New Guinea origin with a restricted 
distribution in Australia, I have preferred the name proposed by Rand 
and Gilliard if it differs from the Australian name and if the Austra- 
lian name is less appropriate to the New Guinea population. For 
example, the Australian name of Ptilinopus suwperbus, Purple-crowned 
Pigeon, would be confusing in New Guinea, where there are several 
additional species of pigeons with purple crowns, whereas the name 
used by Rand and Gilliard, Superb Fruit Dove, had already been 
applied to this species in several previous books and monographs 
on New Guinea birds or southwest Pacific birds. Some names 
proposed by Rand and Gilliard present problems of consistency 
or suitability. For instance, Eugerygone rubra, Red-backed Warbler, 
is no longer considered a warbler; /frita kowaldi, Blue-capped Bab- 
bler, and the three species of Crateroscelis, Mouse-babblers, are 
no longer considered babblers; Gerygone ruficollis, ‘Tree-fern Gery- 
gone Warbler, is much more characteristic of other habitats than 
of treefern fields; and Acanthiza murina, De Vis ‘Tree Warbler, 
is the sole New Guinea representative of a genus of which the other 
twelve species live in Australia and are all called thornbills (Western 
Thornbills, Tasmanian Thornbill, Brown ‘Thornbill, etc.). In these 
cases I have either modified the name proposed by Rand and Gilliard 
or else substituted a name proposed by Schodde and Hitchcock (1968 
and pers. comm.). 

Seven new races based on my collections have been described previ- 
ously (Diamond, 1967a), and no new names are introduced in this 
monograph.

SPECIES ACCOUNTS 


In evaluating the validity of proposed subspecies, I used as a stan- 
dard the admirably thorough, sound, and consistent taxonomic analy- 
ses of Mayr and Rand (1935, 1937) and of Rand (1936, 1938a, 1938b, 
1938c, 1941a, 1941b, 1942a, 1942b) based on the collections of the first 
three Archbold expeditions. Of the 99 New Guinea bird forms de- 
scribed by Rand, there is no instance in which I was unable to discern 
the characters cited in the diagnoses in the Archbold reports. Con- 
versely, I have found no population of which Rand had adequate 
material and in which I could detect reliable taxonomic characters 
warranting naming but which Rand had refrained from naming. A 
uniform and consistent taxonomic treatment for different groups of 
birds and for different parts of New Guinea is an obvious prerequisite 
for drawing undistorted conclusions about evolution, zoogeography, 
and other biological problems of general interest, and the opportunity 
to extract such conclusions seems to me to furnish the only significant 
justification for concerning oneself with subspecies. In reviewing races 
proposed since 1942, I have, accordingly, synonymized those races 
which would not be considered distinct by the standards of the Arch- 
bold reports. 


CASUARIIDAE: CASSOWARIES 
Casuarius bennettti shawmayerit Rothschild 


Dwarf Cassowary 


NATIVE NAMES. Fore: dmanani. Gimi: amananic. Daribi: képi. Pidgin En- 
glish: moruk. 

TAXONOMY. Apparently only one specimen of this species 
known to have originated from a definite locality in the Eastern High- 
lands has been taxonomically analysed. This was a female from the 
Hagen Range, assigned by Sims to shawmayeri, a race originally de- 


scribed from the Kratke Mountains at the eastern end of the Eastern 
Highlands. 


BREEDING. Gimi natives told me that eggs are found in March 
and April, suggesting breeding towards the end of the rainy season. 


DISCUSSION. Dwarf Cassowaries live in virgin forest of hills and 
mountains up to about 7,000 ft, apparently in low numbers. ‘They are 
shy and rarely seen but betray their presence by their droppings, con- 
sisting of pits of large fruit which evidently represent their principal 
food. When cornered, they defend themselves with powerful kicks: 
Paran’s dog had been killed by a cassowary, and Gilliard (Mayr & 
Gilliard, 1954) saw a human attacked and nearly killed. From native 
accounts the adults are solitary and may be accompanied by one 
young bird. ‘The meat is dark and said to be not unlike human flesh; 
the large green eggs are eaten; and the feathers are used as brooms

and as decorations at native sing-sings. Captured young birds are kept 
as pets in villages until large enough to eat. 


Casuarius casuarius subsp. 
Double-wattled Cassowary 


Native informants at Karimui stated that two cassowaries occur 
there. One was said to be a smaller bird, living on the mountain 
slopes; I have seen captives kept by natives, and it is Casuarius ben- 
nettii, the widespread montane cassowary. he cassowary on the floor 
of the Karimui Basin itself was said to be much larger (about the 
height of a man); this description was confirmed by a European resi- 
dent who saw one that had been killed. This second species can only 
be C. caswarius, the large cassowary of the lowlands, whose altitudinal 
range generally appears to exclude that of C. bennetti. If confirmed, 
the occurrence at Karimui would represent an altitudinal record for 
this species, but it would not be surprising in view of the many other 
lowlands species that have colonized the flat basin floor. 


PODICIPEDIDAE: GREBES 
Podiceps novaehollandiae novaehollandiae Stephens 
Little Grebe 


NATIVE NAME. Fore: nosho. 


DISCUSSION. Gyldenstolpe collected one specimen on the Wahgi 
River; Bulmer saw a pair and inspected a nest in the Baiyer Valley; 
and natives report grebes as present in the Fore area.

and in a marsh near Okapa. ‘The two New Guinea races differ only in 
size; Gilliard’s specimen agreed with the smaller pelewensis, while 
specimens taken by Gyldenstolpe and Shaw-Mayer agreed with rogersi.

males that I measured, collected at altitudes above 10,000 ft on Mt. 
Wilhelm, in the Snow Mountains, and in southeastern New Guinea, 
have wings of 195-201 (197 + 3) mm, larger than either of the Soli- 
abeda males (from 1,350 ft, at the lower altitudinal limit of the 
species). 

BREEDING. Both males had enlarged testes. One of the males 
was shot with the female, which contained an egg nearly ready to lay 
as well as several other enlarged ova. On 27 July 1965 Paran found 
a nest, a depression in a rock next to the Wi River, lined with erass 
and containing three pale coffee-colored eggs. ‘hus, Salvadorina’s 
breeding at Soliabeda falls in the dry season, which is teleologically 
understandable: after rains in their watersheds, small highlands 
streams are subject to sudden flash floods, which would immediately 
destroy a nest like the one Paran found. Van Deusen (pers. comm.) 
discovered the first known nest, in vegetation near the alpine lakes on 
Mt. Wilhelm. 


DISCUSSION. Of the 13 species of Anatidae reported from New 
Guinea, this is the only endemic species, and the only one that fails 
to descend to the lowlands. Most of the remaining 12 species are 
largely or entirely confined to the lowlands. The poor representation 
of Anatidae in the mountains is what one would expect from the very 
small number and size of New Guinea’s montane lakes. 

Single individuals of Salvadorina were seen several times on the Wi 
River (1,350 ft) and Sena River (4,500 ft), which are rocky, turbulent, 
and narrow mountain streams. In some cases the bird was perched on 
boulders in the middle of the torrent, while in other cases it was first 
noticed as it took flight, taxiing low over the surface of the water 
instead of bounding straight up with a spring (cf., also, Mayr and 
Rand, 1937, p. 11). To judge from reports of native informants, Salva- 
dorina is a regular but uncommon inhabitant of rushing torrents on 
mountain slopes in the Eastern Highlands. ‘The unusually low eleva- 
tion of Soliabeda records is probably attributable to the fact that the 
Wi River was still turbulent and in mountainous terrain. In addition, 
Salvadorina occurs in another quite different habitat, namely, the 
alpine lakes between 10,000 and 13,000 ft in the Snow Mountains, 
Eastern Highlands, and southeastern New Guinea. Gilliard and Van 
Deusen both observed it in the twin alpine lakes on Mt. Wilhelm. 


Netlapus coromandelianus coromandelianus (Gmelin) 
White-quilled Pygmy Goose 
H. L. Bell (pers. comm.) states that L. W. C. Filewood found this 


species abundant at Lake Kandep (7,000 ft).

ACCIPITRIDAE: HAWKS and EAGLES 
Elanus caeruleus wahgiensis Mayr and Gilliard 
Black-winged Kite 


On 29 June 1965 I observed one individual over grassland at Tarabo 
airstrip (6,000 ft) near Okapa. It flew back and forth 10-30 ft above 
the ground, periodically stopping to hover in one spot. The manner 
of hovering was distinctive: the axis of the body was inclined to the 
horizontal at about 45°, head upwards, and the wing strokes were 
entirely in a plane above that of the body. This behavior is essen- 
tially the same as that of Elanus leucurus (sometimes considered con- 
specific with E. caeruleus) which I have observed in South America. 

Gilliard collected the type specimen and observed others in the 
Wahgi Valley. There are also sight records by Bulmer and Bell at 
Baiyer River (3,600 ft) and from Pureni in the western part of the 
Eastern Highlands (N.G.B.S. Newsletter, No. 23, p. 4, Sept. 1967). 
The expanses of the Eastern Highlands cleared by man seem ideal 
habitat for this species, and it is surprising that it should be so local 
and uncommon.

TAXONOMY. ‘The races stenozona of western New Guinea and 
megala of eastern New Guinea differ only in size. Wing measurements 
of comparative material yielded 272-305 (284 + 14) for five stenozona 
males, 306 and 311 for two megala males. Values given by Rand and 
Gilliard (1968) are: stenozona, g 290-303, 2 296-314; megala, ¢ 298- 
316, 9 314-334. The present material is thus closer to stenozona. A 
single immature female taken at Lake Kutubu by Schodde and Hitch- 
cock had a wing of 294 mm and was also assigned to stenozona. ‘The 
barring on the underparts of my four specimens is darker than in 
most other material, nearly charcoal. 

BREEDING. Although the male and female from Mt. Karimui 
were together as a pair, the gonads of these four specimens were small. 


DISCUSSION. Individuals or groups of up to five were seen soar- 
ing high or else perched in tall trees overlooking open spaces. Once I 
saw a bird attacked and driven off by the flycatcher Peltops montanus.

Henicopernis longicauda longicauda (Garnot) 
Long-tailed Buzzard 


While hawks in general are not numerous in the Eastern Highlands, 
this species is among the less uncommon. Until one learns to recog- 
nize it in flight, however, Henicopernis is easy to overlook entirely, 
since it is usually seen soaring rather high. ‘The wings are long, 
rounded, and broad, the head is small, and the tail is long, rounded, 
and slender, so that the silhouette suggests three long loops and one 
short loop attached at a point and radiating at right angles. ‘he pat- 
tern of the undersurface is also distinctive, the head, upper breast, 
wings, and tail appearing dark, the lower breast and belly light. ‘Vhe 
primaries are often held outstretched. With practice the combination 
of the distinctive shape and undersurface pattern enables one to recog- 
nize Henicopernis at a moderate distance. It is rarely seen sufficiently 
close for the barring of the wings and tail to be visible. I saw it regu- 
larly in all parts of the Eastern Highlands over both cleared country 
and forest, usually soaring without flapping, sometimes alternately 
soaring and flapping. About half of my observations were of pairs or 
of groups of three birds. One pair was seen to chase off an individual 
of the kite Haliastur indus. 


Milvus migrans affinis Gould 
Black Kite 


NATIVE NAME. Fore: kékepa. 


DISCUSSION. In the Eastern Highlands this species is widespread 
in districts with large expanses of man-made grasslands (but is absent 
at Karimui, where grassland is limited and probably recent in origin). 
It gathers in large numbers at the leeward side of grassland fires in 
wait for fleeing grasshoppers, and searches the ground for burnt prey 
once the fire has passed. Elsewhere in New Guinea Milvus migrans is 
a lowlands species and has not been recorded even from the extensive 
man-made grasslands of the Baliem Valley of western New Guinea. I 
do not know whether it breeds in the Eastern Highlands or whether 
it is a seasonal nonbreeding visitor from the lowlands. The birds I 
watched were always soaring low over the ground in the manner of a 
harrier (Circus). ‘The indented tail, unique among New Guinea hawks, 
facilitates identification in silhouette.

DISCUSSION. ‘This species, Henicopernis longicauda, and Milvus 
migrans are perhaps the commonest hawks of the Eastern Highlands. 
‘The chestnut and white adults are unmistakable, while the imma- 
tures may be recognized in flight by the light “window” in the distal 
half of the wing. I found Haliastur indus widespread (Okapa, Lufa, 
Karimui) up to 6,600 ft, and Bulmer found a nest at 4,000 ft. It was 
usually seen soaring over open country, generally singly but sometimes 
in groups of up to four. About once a month it came to eat spiders 
out of their webs near the European houses at Okapa, and one indi- 
vidual was seen with a rat, but much of the diet is insects caught on 
the wing. A soaring individual was chased off by a pair of Henicoper- 
nis longicauda. While this is mainly a lowlands species, the ‘Third 
Archbold Expedition (Rand, 1942b) and Ripley (1964) found that it 
has also colonized the man-made grassland of the Baliem Valley of 
western New Guinea.

chestnut, the chestnut being darker on the flanks and shanks and ab- 
sent on the throat. There are small black streaks on the throat, bold 
black streaks on the breast, flanks, and shanks, and black spots on the

lower belly and undertail coverts. The axillaries are rufous with black 
centers, and the undersurface of the primaries and tail alternately 
barred black and white. 

Only about seven other specimens exist, of which two were available 
for comparison: the type of Accipiter eudiabolus Rothschild and Har- 
tert, an unsexed adult (presumed male from its measurements) from 
Babooni at 3,000 ft in the mountains of southeastern New Guinea; and 
an immature, also presumed to be male, from the Hydrographer 
Range of southeastern New Guinea. ‘The Babooni adult has the head 
and upperparts black, the underparts white with bold black streaks, 
and the feathers of the upperwing coverts black with broad chestnut 
edges; wing 295, tail 201, exposed culmen 22 mm. ‘Vhe Hydrographer 
Range immature has the head, upperparts, axillaries, and underparts 
of the body mainly rich chestnut, with bold black streaks below and 
black centers to the feathers of the upperparts; wing 292, tail 206, ex- 
posed culmen 21 mm. In both of these specimens, as in the Karimui 
bird, the undersurface of the wings and tail is barred black and white. 
The Karimui specimen is thus not fully adult but more nearly so 
than the Hydrographer Range specimen, from which it differs in that 
the chestnut wash of the axillaries and underparts is paler, the ground 
color of the throat and a few patches on the breast and undertail 
coverts are already pure white, and the black centers of the back 
feathers have increased at the expense of the chestnut peripheries, 
especially on the upper back. 


DISCUSSION. Accipiter buergersi, the rarest species of hawk en- 
demic to New Guinea, is apparently confined to low altitudes (1,900- 
5,200 ft) in the mountains of eastern New Guinea. Besides Karimui 
and two or three localities in southeastern New Guinea, the other 
localities where it has been taken are Junzaing on the Huon Peninsula, 
the type locality of Maeanderberg and the Lordberg in the mountains 
south of the Sepik River, and the Sau Valley of the Eastern Highlands, 
where Bulmer collected one specimen at 5,200 ft (5 Dec. 1955). 

In the upper part of the altitudinal range of Accipiter buergersi 
there is no other forest Accipiter, but in the lower part of its range it 
is one of three forest species in its genus. The three species differ in 
size, each being about 50% heavier than the next: A. buergersi > A. 
novaehollandiae > A. poliocephalus.

is characteristic of ‘Tasmania; only the colored phase occurs in the 
D’Entrecasteaux Archipelago (subspecies pallidimas) and the Louisi- 
ade Archipeiego (subspecies misulae); and both phases occur on New 
Guinea in roughly equal proportions or with the colored bird slightly 
more common. In New Guinea Accipiter novaehollandiae is mainly a 
lowland species, although it does reach the Baliem Valley of the west- 
ern New Guinea mountains. In the Eastern Highlands it is not known 
to occur outside of the Karimui Basin; it was even absent at Soliabeda 
(2,000 ft) nine miles southeast of Karimui Patrol Post but beyond the 
mountains ringing the basin. ‘This isolated Karimui population is re- 
markable in that both of the above specimens, and all individuals seen 
by me in 1964 and 1965, were melanistic, i.e., a uniform dark gray- 
brown. The only other record of melanism in this species is a single 
female from the Hydrographer Mountains of southeastern New 
Guinea. According to Karimui natives, the dark phase (‘“kemorage’’) 
is resident at Karimui throughout the year and nests at the tops of 
very tall trees, while individuals of the white phase (“penago’”’) appear 
only infrequently and disappear after a few days. ‘(he occurrence of 
geographically localized melanistic, white, and colored phases is of 
interest, as is the extremely limited range of the melanistic form in 
an ecological island surrounded by areas where only the other two 
forms occur. 


BREEDING. ‘The gonads of the 1965 males were small. 


DISCUSSION. I found solitary individuals at Karimui and Bomai 
in trees overlooking gardens and cleared areas.

DISCUSSION. At Karimui the habitat preference and behavior 
of Accipiter fasciatus appeared similar to those of Accipiter novaehol- 
landiae, i.e., solitary individuals were seen perched in trees overlooking 
native gardens and open spaces. A perched immature was repeatedly 
attacked by the flycatcher Rhipidura leucophrys and finally flew off 
with the flycatcher in pursuit. Other Eastern Highlands records are 
from the Wahgi Valley, where Gilliard and Gyldenstolpe found it 
“not common” to “fairly rare,’ and from Kyaka territory, where Bul-

other two Accipiter species in the Karimui Basin (A. novachollandiae

STOMACH CONTENTS. A small bird. 


TAXONOMY. The single available specimen of the nominate 
race, which is confined to the Vogelkop, is blacker above, especially on 
the head, and darker below than my two specimens or other schista- 
cinus material. 


BREEDING. ‘Testes of both specimens were small. 


DISCUSSION. Both specimens were obtained in the interior of 
virgin montane forest, remote from human disturbance. The Awande 
specimen was shot while perched at the top of a tree; the Mt. Karimui 
specimen (ca. 6,800 ft) was driven into a mistnet by my Fore assistants 
while it was trying to eat a small dicaeid Melanocharis versteri trapped 
in the net. Another specimen that subsequently escaped was netted 
at 8,500 ft inside the forest on Mt. Michael, where it too had presum- 
ably been after a netted bird and become trapped of its own efforts. 
One individual was surprised on the ground in the forest and flew 
into the treetops. The habit of preying on other birds is responsible 
for its Fore name, “amaipana’”’, which means “killer of one’s brother.” 

This species has generally been considered rare although widespread, 
and less than 30 specimens exist. It nevertheless occurs regularly in the 
Eastern Highlands, even if at a low density, from at least 5,500 ft to 
8,700 ft wherever there are large expanses of forest undisturbed by 
man. Thus, I obtained one specimen each at my three midmontane 
stations; and Gilliard, Gyldenstolpe, Shaw-Mayer, and Bulmer each 
collected one to three specimens in the Wahgi Mountains, Kubor 
Mountains, Schrader Range, Mt. Hagen, and Mt. Giluwe. It is the 
only forest Accipiter in this altitudinal range and is replaced in the 
forest at lower elevations by A. poliocephalus and A. novaehollandiae 
(and the very rare and geographically limited A. buergers?). On Mt. 
Karimui a vertical distance of 1,800 ft separated the sites where A. 
melanochlamys and A. poliocephalus were netted. Records elsewhere 
also suggest that altitudinal segregation of A. melanochlamys trom its 
forest congeners is complete.

CULMEN FROM CERE. 25. 

BREEDING. ‘The testes were small. 

DISCUSSION. ‘The monotypic genus Megatriorchis is one of the 
rarest endemic New Guinea hawks. The above specimen was brought 
in by a Soliabeda native, who spotted it perched: ima thee inside the 
forest. He hid in the undergrowth, made noises imitating a small bird, 
and shot the hawk with bow and arrow when it came down to investi- 
gate. The previous day I had seen probably the same individual 
perched inside the forest in the crown of a flowering tree, which had 
attracted many small birds and butterflies. During the 15 minutes that 
I watched the hawk, it remained stationary. Megatriorchis doriae has 
been recorded from forest at altitudes up to’ 3,000 Ir atea number of 
localities scattered over New Guinea. 


Harpyopsis novaeguineae Salvadori 
New Guinea Eagle 

NATIVE NAMES. Fore: tiyé6. Gimi: luipa. 

DISCUSSION. Harpyopsis, the largest endemic New Guinea hawk, 
is quite uncommon but widely distributed in the Eastern Highlands, 
inhabiting forest up to about 9,500 ft. The individuals I observed 
were either soaring just over the top of the forest or else perched 
inconspicuously inside the forest in the crowns of trees. ‘The most re- 
markable feature of this eagle’s habits is that it hunts by night as well 
as by day, and at one camp the calls of a pair of Harpyopsis awakened 
me repeatedly throughout the night. In life the feathers around the 
eye form a distinct facial disc, as in owls, and may play some role in 
night vision or hearing. ‘he prey consists of large marsupials and 
birds and small pigs. 

VOICE. A single note with a quality like the sound made by a 
taut bowstring being released, followed by a hollow note repeated one 


to four times and like the foraging call of a domestic chicken: bung!

grassland near Okasa (4,250 ft) in June 1965. The other Eastern High- 
lands records are from grassland at Nondugl, where Gilliard and 
Gyldenstolpe each saw it a few times, from grassland near Mt. Giluwe, 
where Shaw-Mayer observed it often, and from gardens and grassland 
in the Baiyer Valley and Schrader Range, where it was found by Bul- 
mer. Its distribution is evidently quite local, and I interpret my failure 
to find it in the grasslands at Okapa, Lufa, and Karimui as probably 
indicating its being actually absent from those localities, since the 
distinctive male is easy to recognize even at a distance.

that there are a few white patches on the lower back, the nape is largely 
white, and the forehead and area around the base of the bill light gray. 


DISCUSSION. ‘This Australian and New Zealand race was pre- 
viously known in New Guinea mainly or only from sea level on the 
southern coast, and provides yet another example of a lowland species 
reaching the Karimui Basin. The Second Archbold Expedition (Rand, 
1941a) found both this form and Circus spilonotus spilothorax at Lake 
Daviumbu in the same month, strengthening the case for considering 
them as separate species. At Merauke C. approximans is present onlv 
in the dry season and C. spilonotus only in the wet season (Hoogerwerf, 
1964).

DISCUSSION. ‘This is apparently the only specimen collected to

the surviving mate, appeared over the village. In addition, on several 
occasions at Miarosa (5,800 ft) in June 1964 I observed a pair repeatedly 
alight in the top of a tall dead tree, take off, circle, and return to the 
same perch. Finally, I saw one individual in Gimi territory (5,000 ft) 
in July, 1964. Thus, Falco severus may be regarded as local and un- 
common in the Eastern Highlands in open country with tall trees.

DISCUSSION. Falco c. cenchroides is an Australian bird for which 
there were no New Guinea records until recent years, when it began 
to turn up as a winter visitor (March to September) in southern New 
Guinea, (N.G,B.S. Newsletter, No. 10) pe 2; Aug, 1966; No, 14, p. 3, 
Dec. 1966; No. 43, p: 1, May 1969; No. 44, p. 1) July 1969; van den 
Assem, 1960). As discussed previously (Diamond, 1967a), my specimens 
were collected in June and July of 1965, when I frequently saw this 
falcon flying over the Karimui and Bomai airstrips. In addition, I saw 
an individual over Karimui airstrip in June 1966 and in April 1969, 
and a photograph of a falcon shot by the patrol officer at Karimui in 
1964 establishes it as this species. ‘he fact that all specimens were 
females with small ovaries suggests that they were nonbreeding 
vagrants. Stresemann (1914a) pointed out earlier that the records of 
Falco c. cenchroides outside of Australia (from New Zealand, Java, 
Babbar, Ceram, and the Aru Islands) are nearly all females.

BREEDING. ‘The testes were small. 


DISCUSSION. In addition to the specimen collected, I observed

perched in trees in gardens or open country, and twice I saw pairs 
chasing each other, diving and twisting rapidly and calling. Gylden- 
stolpe and Bulmer also collected specimens. ‘Thus, this falcon may be 
widespread, but uncommon, in the Eastern Highlands in open country 
(never in the forest interior). 

VOICE. The pairs chasing each other uttered a very rapid series 
of harsh notes on one pitch delivered at machine-gun rate; this could 
alternatively be described as a crackling scream. ‘This series was some- 
times punctuated by two more emphatic notes.

(above 4,000 ft), and at Awande (6,000 ft), where Paran collected it. 
It also occurs in Kyaka territory, where natives brought eggs to 
Bulmer on several occasions. In much of its range this is a lowland 
species, but the Third Archbold Expedition (Rand, 1942b) found it 
up to 4,000 ft in the Snow Mountains, and Greenway (1935) recorded 
it up to 5,700 ft in the Herzog Mountains.

NATIVE NAMES. Fore: 6a. Gimi: alofya. Daribi: wadi. 
112 


SPECIES ACCOUNTS 


DISCUSSION. Some species of Talegalla is widespread in the 
Eastern Highlands. On Mt. Karimui, between 5,000 and 6,500 ft, I 
heard calls virtually identical to the calls of Talegalla jobiensis that I 
heard on the north coast. My native assistants reported Talegalla in 
the Okapa area below 6,000 ft, and down to at least 2,000 ft in the 
Karimui area. At Lake Kutubu Schodde and Hitchcock observed a 
Talegalla which they assumed was T. fuscirostris, but they did not 
obtain specimens. 

The species of Talegalla involved is uncertain, and its identification 
will answer a question of considerable interest. ‘There are three species 
of Talegalla, which are very similar morphologically and nearly but 
not quite allopatric: T. cuvieri of far western New Guinea, T. fusci- 
rostris of southern New Guinea, and T. jobiensis of northern, north- 
eastern, and southeastern New Guinea. T. fuscirostris is a lowland 
species, apparently not recorded at elevations higher than a few 
hundred feet, whereas T. cuviert and T. jobiensis occur up to 3,000- 
5,000 ft. T. fuscirostris and T. cuviert overlap for a distance of at 
least 150 miles in southwestern New Guinea around long. 136° E, and 
in this area they appear to segregate altitudinally, with 7. cuvierl con- 
fined to higher elevations. T. fuscirostris and T. jobiensis overlap for 
at least 50, perhaps 250, miles in southeastern New Guinea around 
long. 147° E. I would guess that the Talegalla at Okapa and Karimui 
will prove to be T. jobiensis rather than T. fuscirostris, because the 
altitude would be typical of the former and unprecedented for the 
latter, and because the calls of the Karimui Talegalla were indis- 
tinguishable from those of 7. jobiensis. ‘The evolutionary history im- 
plied by these distributions is that genus Talegalla once consisted of a 
superspecies ring of three allopatric forms; and that the range of the 
southern form, T. fuscirostris, is being reinvaded by T. cuviert from 
the west and by T. jobiensis from the east, with the forms segregating 
altitudinally in each overlap zone. 

VOICE. A nasal, unhurried, and very loud call which may be 
rendered “wa-wa-wa’’, suggestive of a child wailing but more nasal 


and deeper, and consisting of two detached upslurs followed by a 
steady note (Fig. 11).

Gilliard, Shaw-Mayer, and me. According to natives, Aepypodius flies

the ground. ‘This is in accord with our observations: an Aepypodius 
seen by Terborgh at Okasa was in a tree, and those that I saw on the 
Sena River were birds which burst up from the ground at my approach 
and alighted heavily in trees.

NATIVE NAME. Fore: yokayo. 

SPECIMENS EXAMINED. Awande: 1 ¢ (20 June 1965). 

WEIGHT. 83. 

WING, 91. 

TAXONOMY. ‘This specimen agrees with topotypical lamonti 
males. Its upperparts are more chestnut and richly colored than those 
of mafulu, while dogwa and plumbeus differ in the tendency towards 
uniform gray coloration of the underparts. 

BREEDING. The testes of the specimen (collected in June) were 
enlarged. On 18 August 1964 a Fore man at Awande showed me a 
nest on the ground in grass containing five eges (one 33 x 24 mm) 
colored very pale tan with dark brown speckles. ‘The “yékay6” was 
said to be generally nesting then at Awande, which implies that breed- 
ing is in the dry season, as true of most other grassland birds as well. 

DISCUSSION. I found small groups of this quail not uncommon 
in grassland and native gardens at Miarosa, Awande, and Okasa. Other 
collectors have also encountered it regularly in the Eastern Highlands 
wherever there are substantial expanses of midmontane grassland and 
gardens. In southeastern New Guinea, but not in the Eastern High- 
lands, it also occurs in alpine grassland.

TAXONOMY. The race giluwensis, described from Mt. Giluwe 
(Sims, 1954), was characterized as lacking the chestnut collar of hors- 
brughi, smaller than furva, and paler below than furva or horsbrughi. 
Only one specimen each (both females) of giluwensis and horsbrughi 
was available for comparison. ‘The Okasa male agrees with gilwwensis 
in lacking the chestnut collar of horsbrughi; the orange-brown color of 
the breast 1s richer than that of giluwensis but less rich than that of 
horsbrughi; the color of the lower belly is pale buff as in horsbrughi,

not white as in giluwensis. The wing length is close to that of the two 
known males of giluwensis, given as 65 mm by Sims (1956). (Rand 
(1942a) gives the wing of one male horsbrughi as 72 mm, and the male 
of furva is unknown). This meagre material is insufficient to assign 
the Okasa population racially but suggests that it is intermediate 
between giluwensis and horsbrughi. 

DISCUSSION. The Okasa specimen, which apparently is the fourth 
known New Guinea male of this rare species, was captured by hand by 
a Fore man in grassland. The other Eastern Highlands records of this 
somewhat local species are from Awande, Mt. Giluwe, and Nondugl.

DISCUSSION. All four specimens were trapped in grassland by 
natives. Most other collectors in the Eastern Highlands have also 
obtained trapped specimens. ‘The species is evidently fairly common 
but secretive in grassland from 5,000 to 8,000 ft. It is absent at Karimui,

Gilliard, Gyldenstolpe, Shaw-Mayer, and Bulmer all found this

Rallus pectoralis and R. philippensis differ ecologically in that the 
former prefers dry grassland, the latter swampy areas. I never encoun- 
tered Rallus philippensis, and Awande natives appeared not to know 
it, probably because the grassland at Awande was all dry.

‘TAXONOMY. ‘These two specimens differ from nominate forbesi 
of southeastern New Guinea in the much shorter tail, and in this 
respect agree with steznz, originally described on the basis of a single 
female from the Weyland Mountains in far western New Guinea. The 
larger series obtained by Gilliard, Gyldenstolpe, and Shaw-Mayer all 
showed great variation in plumage. In addition, specimens from Mt. 
Giluwe had tails as long as those of nominate forbesi, while those from 
various locations in the Wahgi Valley had short tails. The suggestion 
of Sims (1956) that this variability of Rallicula forbesi in the Eastern 
Highlands is due to recent reestablishment of breeding contact be- 
tween the western race steini and the eastern race R. f. forbesi follow- 
ing a period of isolation is a plausible one, since the details of 
distribution in the genus Rallicula suggest that these rails have become 
isolated, differentiated, and reinvaded each other’s ranges often (Dia- 
mond, 1969). 


DISCUSSION. Rallicula forbest goes about on the ground in 
parties of a few individuals inside primary midmontane forest between 
4,200 and 9,500 ft. It is secretive and uncommon but nevertheless 
widespread, and has turned up at almost all forest collecting stations 
in the Eastern Highlands within these altitudinal limits.

TAXONOMY. ‘The specimen agrees with the New Guinea race 
R. t. tricolor, and differs from the Australian race robinsoni (Cape

DISCUSSION. ‘The specimen provides the sole record for the 
Eastern Highlands, and also represents an altitudinal record for this 
lowland species, rarely found more than a few hundred feet above 
sea level.

TAXONOMY. A. o. ruficrissum of northern Australia and south- 
ern New Guinea differs from A. 0. moluccanus of the remainder of 
New Guinea in the lighter belly and more rufous, less dull undertail 
coverts, and in that the male has a red base to the culmen, lacking in 
moluccanus. The Karimui material is somewhat intermediate but 
nearer ruficrissum in the color of the belly and undertail coverts; the 
male has a red-orange base to the culmen. ‘The juvenile is uniformly 
black. 

BREEDING. All four adults had enlarged gonads. ‘This fact, plus 
the record of the juvenile not more than a few days old taken in early 
July, implies that breeding is in the dry season, as true for most grass- 
land birds. 

DISCUSSION. ‘This moorhen was present at Soliabeda as well as 
at Karimui and was also collected by Schodde and Hitchcock at Lake 
Kutubu. In the Karimui area and in other parts of New Guinea 
where I encountered it, it lived in the tall grass that had grown up 
around gardens and cleared land, remote from any swamp. It was far 
more often heard than seen and proved impossible to flush; it merely 
remained out of sight in the grass when disturbed. 

VOICE. As described in detail elsewhere (Diamond and ‘Terborgh, 
1968), the commonest vocalization in this species is a duet, in which 
each bird of a pair alternately utters a cat-like wail lasting about a 
second and beginning just as the wail of its partner concludes. During 
the performance the birds move about in the tall dense grass, several 
feet apart, and remain out of sight of each other. The duet is often 
given at night as well as during the day. Solo calls consisting of a low 
irregular, hen-like “chuck-chuck-chuck” or “kuk-kuk” or “bk-bk-bk”’ 
are heard infrequently. 


Gallinula tenebrosa subsp. 
Dusky Moorhen 


In 1951 a European resident at Nondugl showed Gyldenstolpe 
colored photographs of two moorhens which had been shot near the 
Wahgi River and which Gyldenstolpe identified as this species. ‘There 
is no other record from the Eastern Highlands and only a few scat- 
tered records from other parts of New Guinea. 


Porphyrio porphyrio subsp. 
Purple Swamp Hen 


Gilliard and Gyldenstolpe found evidence of the presence of swamp 
hens in swampy grass near the Wahgi River, and Gilliard secured one 
specimen. Bulmer obtained a sight record at Wabag (6,000 ft) in 
January 1956. ‘The species occurs mainly in the lowlands but has also

letter No: 23,7p. 2, sept. 196))): 


COLUMBIDAE: PIGEONS 
Diets of New Guinea Pigeons 


‘The genera of New Guinea pigeons differ in diet. Ptilinopus, 
Megaloprepia, and Ducula take only fruit whose flesh is soft enough 
to crush between one’s fingers, and the stomachs of these genera never 
contain gravel. ‘The size of fruit eaten varies with the size of the bird, 
from 6 mm in diameter for the smallest Piilinopus to 50 mm for the 
largest Ducula. In Columba, Macropygia, Reinwardtoena, Chalco- 
phaps, Gallicolumba, Caloenas, and Otidiphaps the stomach often or 
usually contains gravel, sand, or stones (up to 10 mm in diameter in 
Caloenas and Otidiphaps). Correspondingly, the diet of these genera 
consists of hard fruit, nuts, and seeds, occasionally supplemented by 
insects in Chalcophaps and Gallicolumba. ‘The stomach wall of Calo- 
enas is especially thick and muscular. 


Niche Differences in Genus Ptilinopus 


In the Papuan region there occur 13 species of Piilinopus, of which 
nine range virtually over the entire island of New Guinea, one is con- 
fined to the north coast (P. viridis), and three fail to reach, or else 
barely reach, the main island of New Guinea. All are mainly green in 
color, medium-sized to small, arboreal, and live on soft fruit. ‘The 
vocalizations of all 10 species with which I am familiar are a confusingly 
similar series of low ‘“‘coo’s’” or “‘hoo’s”. Above 5,000 ft one encounters 
only one species (P. rivoli) or occasionally two (P. rivoli plus P. 


ee

ornatus). At lower elevations it is the rule to find several species locally 
sympatric. For instance, combining results from the three prewar 
Archbold Expeditions and my three expeditions, species lists were avail- 
able for a total of 29 localities at elevations of 4,000 ft or less. At three 
localities, six Ptilinopus species were present; at four localities, five 
species; at five localities, four species; at nine localities, three species; 
at seven localities, two species; and at one locality, one species. Several 
species are regularly seen in a single fruit tree. ‘Vable 4 indicates the 
species present at each of my eight best-studied collecting localities in 
the Eastern Highlands. 

Size differences are a major factor that make this degree of local 
sympatry possible. ‘Thus, approximate average weights of the 10 New 
Guinea mainland species are: P. nanus, 50; P. pulchellus, 75; P. coro- 
miulaius, 75; i, iozonus, 110; P. superbus, 125; P. viridis, 125; FP. 
aurantifrons, 140; P. rivoli, 155; P. ornatus, 165; and P. perlatus, 240. 
The five species that occur regularly at Karimui (P. nanus, P. pulchel- 
lus, P. superbus, P. ornatus, P. perlatus) have weights that successively 
increase by a factor of about 1.5 (50, 75, 125, 165, 240). "wo small 
species with the same weight, P. pulchellus and P. coronulatus, have 
locally complementary distributions so that both rarely occur at the 
same locality. Other ecological differences are that P. ornatus and P. 
perlatus have altitudinal distributions which largely exclude each 
other; that the local distributions of P. ornatus and P. superbus in hill 
forest (below P. rivoli, above most of the other species) tend to be 
complementary; that P. 7ozonus and P. perlatus are more characteristic 
of second-growth and the forest edge than the other species; and that 
P. suwperbus had a synchronized peak of breeding in my study areas at 
a time when all its congeners at the same elevation were in nonbreed- 
ing condition. However, much remains to be learned about ecological 
sorting within this genus.

WING. 4 @: 123, 127, 130, 135. 

STOMACH CONTENTS. Fruit, 7-26 mm. in diameter. 

BREEDING. All of the specimens were males, and all had greatly 
enlarged gonads. One female was observed at Karimui and another at 
the Sena River but none at Okasa, where males were particularly 
numerous. Perhaps the females at Okasa were remaining out of sight 
on nests, unless the males arrive before the females. 

At the Sena River in 1964 I found a nest 3 ft off the ground in a low 
bush 30 ft from the river. It was a flimsy stick construction containing 
one white egg measuring 29 x 18 mm. This nest and the enlarged 
testes of the specimens suggest that the peak of breeding occurred in 
the dry season at Okasa, Karimui, and the Sena River both in 1964 
and 1965. Most other fruit eating species were not breeding at this 
time (p. 85). 

DISCUSSION. Ptilinopus superbus was the commonest Ptilinopus 
at Okasa and the only one on the Sena River, but was quite uncommon 
at Karimui and absent at Soliabeda and on Mt. Karimui. In general, 
I have found P. superbus characteristic of forest on hill slopes up to 
about 4,500 ft, largely below the altitudinal range of P. rivoli. Its 
main competitor on the hill slopes is P. ornatus, which is more rigidly 
tied to this habitat but is usually found in localities where P. superbus 
is absent or uncommon. P. superbus occurs irregularly in second- 
erowth and agricultural areas up to about 5,000 ft. It also extends to 
sea level, where it comes into competition with other Ptilinopus 
species. 

The male displays to the female while standing on a branch, by 
puffing up his breast feathers and orange collar, spreading the wings, 
flaring the tail to show the light terminal band, and uttering a rasping 
sound. 

VOICE. ‘The distinctive slow call consists of a single note with an 
‘“m’” sound, followed after a 2-sec pause by a series of three to six 
identical upslurs at I-sec intervals.

TAXONOMY. Of the nine specimens sexed, seven had the testes 
small, while two (Mt. Karimui Zone 2 and Karimui 17 July 1965) 
had the testes somewhat enlarged. It is remarkable that only males 
were collected (females are indistinguishable from males in the field). 


DISCUSSION. Ptilinopus pulchellus was fairly common at Karimui 
and Soliabeda in trees of forest, second-growth, and gardens, and 
Schodde and Hitchcock also found it at Lake Kutubu. It is generally 
distributed elsewhere in New Guinea in forest up to about 2,000 ft, 
occasionally (as at Karimui) somewhat higher. Its ability to coexist 
with several other species of Ptilinopus in this range is probably as- 
sociated with its smaller size. 

One other New Guinea species of Ptilinopus, P. coronulatus, has 
approximately the same size (weight and wing length) as P. pulchellus. 
‘The local distributions of these two species complement each other to 
a striking degree. Thus, on the southern slopes of the Eastern High- 
lands and on the upper Fly River P. pulchellus is present, P. coronu- 
latus absent, while on the northern slopes of the Eastern Highlands, 
on the Sepik River, and on the lower Fly River P. coronulatus 1s 
present, P. pulchellus absent. Out of 23 low-altitude collecting stations 
of the three prewar Archbold Expeditions, 13 supported only P. 
coronulatus, six only P. pulchellus, and only four supported both 
species. On the Vogelkop the Denison-Crockett expedition took P. 
pulchellus at three localities, took P. coronulatus at five different locali- 
ties, and found no locality supporting both species, although all these 
camps were within 100 miles of each other and most were within 10 
miles. There must be some common denominator to the localities 
supporting one species rather than the other, but I cannot discern 
what it is. 


Ptilinopus coronulatus subsp. 


Little Coroneted Fruit Dove 


In Baiyer and Lai Gorges on the northern slopes of the Eastern 
Highlands, Bulmer collected three specimens of this species at 2,000- 
3,000 ft in October 1955. As discussed under the previous species, its 
local distribution largely complements that of the similar sized P. 
pulchellus.

BREEDING. ‘The Okasa male, and one male and one female from 
Mt. Karimui Zone 4, had enlarged gonads. The nest is a flimsy stick 
construction with one egg. 


DISCUSSION. ‘This is the characteristic Ptilinopus of mountain 
forest from about 4,500 to 8,000 ft, occasionally to 9,000 ft, and was 
fairly common at all my montane collecting stations. In addition, I 
obtained four records from lower elevations: one collected at 4,200 ft 
at Okasa, two collected at Karimui (3,650 ft), and an adult male seen 
at Bomai (3,250 ft). In most of its altitudinal range P. rivoli is the sole 
species of its genus except for occasional localities where P. ornatus 
is present. Only the lowest part of its normal range is shared with 
P. superbus. The few individuals that straggle below 4,000 ft (e.g., to 
Karimui and Bomai) are greatly outnumbered by several species of 
congeners at these localities. 

Single individuals or pairs frequent the middle- and upperstories 
of the forest interior, infrequently venturing into trees of second- 
growth. Up to four birds may be seen simultaneously in a fruit tree. 
When perched motionless and silently, which is to say most of the time, 
their green plumage renders them hard to locate in the leafy crowns of 
tall trees. 

VOICE. A series of upslurred “hoo’s,” falling in pitch and greatly 
accelerating as the series progresses. Other species of Ptilinopus (P. 
perlatus, P. aurantiifrons, P. iozonus) have calls to which this same 
description applies, but in no other species is the acceleration so 
marked. Also, softer and slower single “hoo’s” or pairs of “hoo’s,”’ each 
“hoo” initially rising, then usually falling, in pitch.

STOMACH CONTENTS. Fruit, 13-19 mm in diameter. 

TAXONOMY. Racial differences in populations of this species 
from the main body of New Guinea (exclusive of the Vogelkop) form 
a cline around the periphery of the island, broken in the west at the 
Vogelkop, where the nominate race ornatus is quite distinct in pos- 
sessing a purple crown. The opposite extremes in this cline fall in 
northern New Guinea (assigned to P. 0. gestrot) and in southwestern 
New Guinea (P. 0. kaporensis), birds from the southeast (topotypical 
gestrol) being intermediate but closer to the northern populations. 
The distinguishing characters are the color of the breast (darker and 
browner in kaporensis, lighter and more orange in gestrot) and the 
color of the band on the upper back and neck (darker, browner, and 
more richly colored, nearly chocolate, in kaporensis; lighter and more 
olive suffused with orange in gestrot). Material available for compari- 
son included gestroi from the northern slope of the Snow Mountains, 
topotypical gestroi from southeastern New Guinea, and kaporensis 
from the upper Fly River and from Mt. Goliath (southern slope of 
Snow Mountains) but no topotypical kaporensis (Onin Peninsula, 
southwestern New Guinea). ‘The specimens from the southern slope 
of the Eastern Highlands, which geographically are intermediate be- 
tween southeastern New Guinea and the Fly River or Mt. Goliath, 
have the breast darker and browner than any of the comparative ma- 
terial, and this probably means darker and browner even than the 
type of kaporensis, which Rand (1942b) found to compare well with 
the Fly River specimen and most of the Mt. Goliath specimens. In the 
color of the band on the back and neck, however, the Eastern High- 
lands birds agree well with Mt. Goliath and Fly River kaporensis. 
The afhnities of the Eastern Highlands birds are thus with kaporensis 
to the west, not with gestroz to the east. 

BREEDING. ‘The gonads of all specimens were small. 

DISCUSSION. ‘The characteristic habitat of P. ornatwus is forest

of the hill slopes up to 4,500 ft, ranging down occasionally to the base 
of the hills and infrequently reaching the flat country at sea level. The 
slightly smaller P. swperbus is also characteristic of hill forest but, in 
contrast to P. ornatus, is also found frequently in the flat lowlands. 
The distributions of P. superbus and P. ornatus in the hill forest may 
to some extent complement each other, as do those of the smaller P. 
pulchellus and P. coronulatus in the lowlands. For instance, P. ornatus 
was common at Soliabeda and Karimui, quite uncommon at Okasa, 
and absent at the Sena River, while P. superbus was absent at Solia- 
beda, quite uncommon at Karimui, and common at the Sena River 
and Okasa. 

In addition, I saw P. ornatus once at 6,500 ft in moss forest on Mt. 
Karimui, separated by 3,000 vertical feet from the population on the 
floor of the Karimui Basin. There are at least five other instances of 
detached populations of P. ornatus at altitudes well above its usual 
upper limit (ca. 4,500 ft): 7,100 ft in heavily mossed forest on the 
northern slope of the Snow Mountains (Rand, 1942b), 5,200 ft in moss 
forest on Mt. Menawa in the North Coastal Range (my 1966 expedi- 
tion), Bijenkorf on the southern slope of the Snow Mountains (Junge, 
1937), and the camps of Lord Rothschild’s collector, A. S. Meek, on Mt. 
Goliath in the Snow Mountains and on the upper Angabunga River 
in southeastern New Guinea. ‘The only other species of Ptilinopus at 
all six of these high-altitude localities was P. rivoli, which weighs ap- 
proximately the same as P. ornatus. How P. ornatus and P. rivoli sort 
out ecologically in these high-altitude areas of local sympatry is un- 
known.

WING. 3°: 154% 157, 157. 3 9: 150; 152; 155. 


BREEDING. All specimens had small gonads. 


DISCUSSION. At Karimui this species and its smaller relative P. 
ornatus were the two commonest species of Ptilinopus and fed together 
in the same fruit trees. The two species are very similar in pattern and 
are more closely related to each other than either is to any other 
species. However, their typical altitudinal and habitat preferences are 
totally distinct, and their occurrence together at Karimui is excep- 
tional. Whereas P. ornatus is usually found on the hill slopes and rarely 
reaches sea level, P. perlatus is usually confined to the lowlands, and 
Karimui represents an altitudinal record for it. At the lower elevation 
of Lake Kutubu (2,450 ft) Schodde and Hitchcock found P. perlatus

very common but did not obtain P. ornatus. In my experience, P. 
perlatus is characteristic of second-growth trees and the forest edge 
rather than the interior of primary forest. Its occurrence in the low- 
lands is quite local, and it must be considered the least common wide- 
spread New Guinea Ptilinopus, except for P. nanus. 

VOICE. A series of low, downslurred “hoo’s,”’ delivered at a rate 
slightly less than one per second. The rate is either constant, or else 
accelerates slightly but by much less than does the similar call of P, 
rivoli. Also, a very soft single “hoo” dropping in pitch at the end, with 
or without an initial rise in pitch.

STOMACH CONTENTS. Fruit, 9-22 mm in diameter. 

TAXONOMY. ‘The races to which this Eastern Highlands material 
is related are poliura (southeastern New Guinea), assimilis (Cape York 
Peninsula, Australia), and interposita (type locality the Wandammen 
Peninsula of northwestern New Guinea, also southwestern New Guinea 
from the Onin Peninsula to the Fly River). In the deep, bright yellow 
color of the undertail coverts the Eastern Highlands specimens re- 
semble the type of interposita and Fly River birds, whereas the under- 
tail coverts of poliwra from southeastern New Guinea are paler and 
duller. The wing spots of poliwra are brighter yellow, those of inter- 
posita from the Wandammen Peninsula, Weyland Mountains, and 
southern slopes of the Snow Mountains are more whitish; Fly River 
and Eastern Highlands birds are intermediate in this respect. ‘The 
breast is lightest and reddest in poliura, deeper and more purple in 
interposita from southwestern New Guinea and the type of interposita, 
and still deeper and more purple in Fly River and Eastern Highlands 
birds. In Australia Megaloprepia magnifica becomes more purple 
ventrally and larger as one proceeds from the Cape York Peninsula 
(assimilis) through northern Queensland (ker?) to southern Queensland 
and New South Wales (magnifica). The race assimilis is close to Fly 
River and Eastern Highlands birds in the purple color of the breast 
but is larger. My measurements of the wing yield 4 ¢ 172-188 
(is2 == 7), 9 9 I/G-X6l (E79 = 3) tor assimilis, whereas Fly River 
birds are the same size as Eastern Highlands birds: 5 g 162-173 
C6225), 5 § 158-162 (162 26 4), 

In explanation of these characters, it may be recalled that lower sea 
levels during parts of the Pleistocene created a land bridge, now

covered by the shallow Torres Straits, between the Cape York Peninsula 
of Australia and the Fly River bulge of southern New Guinea. The 
distributions of numerous New Guinea birds and mammals attest to 
the earlier existence of this bridge (Tate, 1952; Keast, 1961). Across 
this bridge the New Guinea and Australian populations of Megalo- 
prepia would have been continuous, and the Fly River bulge would 
have been a meeting point not only of poliwra and interposita but of 
assimilis as well. It seems unwise to dismember these clines further, 
and the Eastern Highlands population is therefore best assigned to 
interposita, since it agrees most closely with this race. The details are 
however of zoogeographical interest and may be briefly summarized: 
Fly River and Eastern Highlands birds are rather different from the 
southeastern race poliwra and stand closest to the western race inter- 
posita, from which they deviate in having a darker, more purple breast 
(assimilis genes) and yellower wing spots (poliwra genes). 

BREEDING. ‘T'wo specimens taken on 11 Sept. 1965, both males, 
had enlarged testes, and one female, taken on 4 Aug. 1965, had some- 
what enlarged ovaries. ‘The other nine specimens sexed (five taken in 
July, four in early August 1965) had small gonads. This seems to 
suggest breeding recommencing at the end of the dry season. ‘The nest 
is a flimsy stick construction on a branch 6-15 ft above the ground, 
with one white egg. 


DISCUSSION. At Karimui and Soliabeda Megaloprepia was less 
common than the commoner species of Ptilinopus, with which it 
shared use of fruit trees in the shaded forest interior while avoiding 
trees of the forest edge and second-growth. It remained within the 
shaded lower half of the crowns, whereas species of Ptilinopus often 
chose exposed perches at the tops of trees after feeding. In addition, 
we heard it once on the lowest part of Mt. Karimui (4,000 ft). It is 
basically a lowland species, and the only other Eastern Highlands 
records are from Lake Kutubu (2,450 ft). 


VOICE. ‘Three deep, equally-spaced notes on virtually the same 
pitch, the whole call lasting about | sec. So well are the sounds ap- 
proximated by the syllables “hoo-wa-hoo” that I initially assumed that 
a man was calling in the forest, and it did not even occur to me to 
consider the possibility that it might be a bird.

TAXONOMY. The race pallida was separated on the grounds 
that “birds from the south slopes of the Oranje Mountains differ 
from all other populations by the decidedly paler breast and abdomen” 
(Junge, 1952, p. 248) and was also characterized as larger than nomi- 
nate rufigaster (Rand and Gilliard, 1968, p. 173). Five specimens col- 
lected by Meek on the Setekwa River, 50 miles west of the type 
locality of pallida (Noord River), do not appear to me paler ventrally 
than other New Guinea populations. The average wing lengths of 11 
populations from various parts of New Guinea, including the popula- 
tion from the Setekwa River, all fall between 192 and 199 mm, with 
a spread of 10 to 25 mm in each population. ‘Thus, the distinctness of 
pallida from rufigaster seems doubtful. 


BREEDING. ‘The testes of the male were small. 


DISCUSSION. At Karimui and Soliabeda this pigeon was quite 
uncommon, solitary, and usually seen perched motionless in the mid- 
dlestory of the shaded forest interior, occasionally at the forest edge.

TAXONOMY. ‘These specimens agree with the race smaragdina 
from the main body of New Guinea, which differs from D. c. chal- 
conota of the Vogelkop in having a longer wing and a greener, less 
purple back. ‘There is some individual variation in the back color, 
which is particularly green in the Miarosa female, more purple in the 
Awande male. 

DISCUSSION. Ducula chalconota, the largest montane pigeon, is 
the high altitude representative of D. rufigaster, occurring uncom- 
monly and as solitary individuals in the middle- and upperstory of 
forest at about 6,000-8,500 ft. I observed it on Mt. Michael and in the 
Okapa area, while Gilliard and Bulmer collected it on Mt. Hagen. It 
was absent on Mt. Karimul.

BREEDING. The 11 Aug. and 13 Aug. males had enlarged testes, 
and the 5 Aug. female had an enlarged ovary, while the July specimens 
had small gonads. ‘Thus, breeding may have been commencing towards 
the end of the dry season, as with Megaloprepia magnifica. 

DISCUSSION. At all my low-altitude stations up to a ceiling vary- 
ing locally between 4,000 and 4,700 ft, Ducula zoeae was a common 
species whose characteristic calls were heard daily. Most of its altitudi- 
nal range, which extends down to sea level, is shared with its less 
common congener D. rufigaster, but D. rufigaster does not extend to 
quite so high altitudes as does D. zoeae. Other records of D. zoeae in 
the Eastern Highlands are at Lake Kutubu (2,450 ft) and at 4,000 ft 
in the Baiyer Valley. 

D. zoeae was usually seen singly or in small numbers, from the 
middlestory up to the crowns of the tallest trees. Unlike D. rufigaster 
and D. chalconota it seemed equally at home at the edge of the forest 
as in the forest interior. ‘The flight is heavy, and the wing beat slow. 

VOICE. A low but resonant series of broken “hoo’s.” Each “hoo” 
rises slightly in pitch, lasts somewhat more than I sec, and is broken

tributed in the Eastern Highlands, and was present at all my collecting 
stations except Mengino and Bomai, ranging up to 11,000 ft in stunted 
moss forest on the summit ridge of Mt. Michael. In the vicinity of 
mountains it sometimes descends to sea level, but it is usually absent

from the flat lowlands. In contrast to most other pigeons in the hills 
and mountains of New Guinea, this is a social bird par excellence. I 
rarely saw a solitary individual, occasionally met pairs, but usually 
found it in groups of three to 30, the average size being about a 
dozen. Flocks perch in tall trees of the forest interior, and if disturbed, 
swiftly circle high over the forest before realighting. In fruit trees 
they keep to themselves and do not mix with other species of pigeons. 
A characteristic habit or display is for flocks to fly down a mountain 
at high speeds along the crest of a steep ridge, dropping thousands of 
feet in a single dive.

TAXONOMY. As previous observers have noted, series of this 
species from the same locality show great individual variation. ‘The 
legs are bright purple, bright red-purple, bright carmine, or bright 
pink in most adult males, dull dark brick-brown in one adult male 
and in immature males, and dull purple, dull brick-red, or dull dark 
brick-brown in females. The bill is pale flesh, light horn-colored, dark 
horn-colored, gray-brown, dark gray, or completely black, and this 
variation does not correlate with sex or other characters. ‘Ihe amount 
of barring on the back, neck, cheeks, and breast of adult females and 
immature males is variable. ‘There is no consistent variation in size or 
in weight with altitude. This large and inadequately understood in- 
dividual variability reinforces the doubts expressed by previous au- 
thors (Gyldenstolpe, 1955; Gilliard and LeCroy, 1961) whether the 
race kerstingi can be maintained as distinct from cinereiceps. When 
comparison is restricted to adult males, specimens from northern New 
Guinea (kerstingi) have slightly darker backs than material from the 
D’Entrecasteaux Archipelago, the type locality of cinereiceps. My East- 
ern Highlands series is nearer kerstingt, less dark dorsally, but darker 
ventrally, as Rand (1942a) noted for Fly River kersting:. Southeastern 
New Guinea specimens are nearer cinereiceps. 


BREEDING. Gonads were small in most specimens, except that 
they were slightly enlarged in two females and one male from Okasa, 
and in one male each from Karimui and Mt. Karimui. 


DISCUSSION. Macropygia amboinensis occurred at all of my 
Eastern Highlands collecting stations except Bomai and the higher 
elevations on Mts. Michael and Karimui, and has also been collected 
by most other workers in the Eastern Highlands. ‘Vhe ecological dif- 
ferenecs between M. amboinensis and M. nigrirostris are complex. Both 
species may be found from the mountains down to sea level, and the 
habitat of both has been recorded as forest or second-growth, depend- 
ing upon the locality. ‘Their local distributions tend to be, but are not 
strictly, complementary, such that only one of the two is common at a 
particular location. Detailed consideration of my distributional records 
and the published records of others suggests the following correlations: 
(1) The most clear-cut difference is that there are practically no records 
of M. amboinensis in deep primary forest above about 5,000 ft, 
whereas M. nigrirostris occurs in forest up to altitudes varying between 
7,000 and 9,000 ft, frequently into the mossy zone. For instance, M. 
nigrirostris is the only species in forest above 5,000 ft on Mt. Karimui 
in my experience and on Mts. Wilhelm, Kubor, and Hagen (Mayr and 


134 


SPECIES ACCOUNTS 


Gilliard, 1954). (2) M. amboinensis is the dominant species in trees of 
open country cleared by man (native gardens, isolated casuarina stands 
in grassland, edge of the forest) above 5,000 ft. ‘This is the case at 
Miarosa and the base of Mt. Michael (present study) in the Wahgi 
Valley of the Eastern Highlands (Mayr and Gilliard, 1954), and in the 
Baliem Valley of western New Guinea (Rand, 1942b). ‘hus, like many 
other lowland species, M. amboinensis has been able to spread upward 
into areas cleared by man. (3) Below 5,000 ft M. amboinensis is the 
dominant species of the forest, as at Okasa, Soliabeda, the lower slopes 
of Mt. Karimui up to 4,500 ft, and many other localities. ‘Vhe exclusion 
of M. nigrirostris from the forest at low altitudes is certainly not com- 
plete, but where M. nigrirostris is common below 5,000 ft, it seems 
generally to be in second-growth, as around Karimui station (3,650 ft) 
and at Lake Kutubu (2,450 ft). The size difference may play a role in 
making possible the local sympatry at lower elevations, since M. am- 
boinensis is about 1.7 times as heavy as M. nigrirostris. 

M. amboinensis was generally seen as solitary individuals or pairs 
in the middlestory of trees, not in the crown. Some practice is re- 
quired to distinguish it in the field from M. nigrirostris. ‘The green- 
naped, light-breasted males of M. amboinensis are easily identified in 
good light. Females and immatures are more difficult to recognize, but 
M. nigrirostris is smaller and its brown of a richer hue. The vocaliza- 
tions of the two species are very distinct. 


VOICE. A series of doubled-noted hoots delivered at the rate of 
one to two per second. ‘The two notes of each hoot are connected; 
the second note is about a major third in pitch higher than the first 
and is accented. Successive hoots do not vary at all in pitch (Fig. 14). 
Some calls of Reinwardtoena reinwardtsi are nearly indistinguishable.

TAXONOMY. While both Macropygia amboinensis and M. nigri- 
rostris have quite variable plumage, two features by which they may 
be distinguished in any plumage are that the uppertail is always barred 
in M. nigrirostris, never in M. amboinensis; and that the bill of M. 
nigrirostris is stouter. 

In the present series the pattern of variation is as follows. Adult 
males have the dorsal surface of the tail barred, the lower back some-

times faintly barred, the remainder of the plumage totally unbarred. 
Adult females have not only the uppertail but also the whole back 
and breast barred. Barring in immatures of both sexes is distributed 
as in the adult female but is heavier, and Gilliard and LeCroy, (1967, 
p. 194) have pointed out detailed differences in barring patterns be- 
tween adult females and immatures. The legs are bright pink or bright 
reddish purple in adult males, dull brick-red in adult females and 
immatures. ‘The bill is black in adult males, a horn-color of varying 
depth in adult females and immatures. 

BREEDING. ‘The gonads were enlarged in two of the three Mt. 
Karimui specimens but in no other material. ~ 

DISCUSSION. ‘The ecological differences between this species and 
M. amboinensis have been discussed under M. amboinensis. In the 
ecologically disturbed area around Karimui Patrol Post (3,650 ft) 
M. nigrirostris was commoner than M. amboinensis. It was absent 
from the primary forest of Mt. Karimui between 4,500 and 6,500 ft 
but reappeared in the moss forest at 6,500-7,600 ft. 

VOICE. Quite different from M. amboinensis, and more reminis- 
cent of Ptilinopus: a quiet series of about a dozen muted “‘coo’s’’ at 
the rate of three or four per second, initially rising and then dropping 
in pitch, slightly decreasing in volume, and with no change in tempo 
(unlike most species of Ptilinopus, which accelerate).

DISCUSSION. ‘This species is fairly widespread at almost all ele- 
vations in the Eastern Highlands but is everywhere uncommon. A 
sighting in Zone 6 of Mt. Karimui was in moss forest, and Gilliard 
found Reinwardtoena up to 11,000 {ft in moss forest on Mt. Hagen. 
All my sightings were of solitary individuals 10-40 ft above the 
ground; some were in deep forest, some at the edge of forest, and one 
in second-growth. The long tail and notably slow wing beat make the 
flight of this graceful pigeon a joy to watch. 

VOICE. There are two distinct calls: a series of disyllabic hoots 
virtually identical to the call of Macropygia amboinensis (Fig. 14,

dropping in pitch, suggesting laughter.

the nape, but they share the most distinctive character of the race, the 
absence of the gray area on the side of the head. The gray edges of the 
upperwing coverts are comparable to those in Setekwa River birds, 
and broader and grayer than in Fly River birds. The races orientalis 
(southeastern New Guinea), septentrionalis (northern New Guinea), 
and nominate rufigula (Vogelkop) all differ in possessing a gray area 
on the head. In addition, the gray edges of the wing coverts are nar- 
rower in septentrionalis, broader in nominate rufigula, and duller and 
less distinct in orientalis than in the Karimui birds. The race helvi- 
ventris of the Aru Islands agrees in lacking the head patch but has 
the covert edgings much more vinaceous. Northern watershed speci- 
mens from the Jimmi Valley were assigned to the northern race sep- 
tentrionalis by Gilliard and Gyldenstolpe, and Gyldenstolpe (1955) 
specifically mentioned the presence of a well-defined gray area on the 
side of the head. 

When examined in March 1966, the two Karimui specimens still 
had the breast quite distinctly washed with yellow-orange, but this 
wash was completely absent in prewar material. Rand (194la) com- 
mented previously on the rapid postmortem fading of this wash. 


BREEDING. ‘The gonads of the male were much enlarged. 


DISCUSSION. Both specimens were collected while on the ground 
in forest. Karimui natives are familiar with the species, but it is evi- 
dently quite uncommon and shy. Like G. beccarit, G. rufigula becomes 
locally abundant when wild bamboo produces seeds.

Gallicolumba beccarw beccarit (Salvador) 
Beccari’s Ground Dove 


NATIVE NAME. Fore: manumu. 

SPECIMENS EXAMINED. Awande: 2 ? (21 June 1964, and 19 June 1965). Men- 
gino: 1 g (16 July 1964). Mt. Karimui Zone 4: 1 9 (30 Aug. 1965); Zone 8: 1 ¢

STOMACH CONTENTS. Gravel and seeds. 


DISCUSSION. ‘This species is widespread but usually uncommon 
in montane forest between about 5,000 and 9,000 ft, and is generally 
the sole species of ground dove at these altitudes. It lives on the ground 
in the forest and is quite shy (all my specimens were netted). Paran 
told me that about once a decade, when the wild bamboo produces 
seeds, G. beccarii appears in enormous numbers at Awande to eat the 
seeds and to nest.

DISCUSSION. All the specimens were solitary and on the ground 
inside the forest. 

The distribution of this species seems highly erratic. ‘The five speci- 
mens from Karimui suggest that it was uncommon but not rare there. 
At Lake Kutubu Schodde and Hitchcock found this species to be the 
common ground dove of the forest interior. Bulmer collected one 
specimen at 6,700 ft, the Fore said that it occurred at Awande, and 
a single trapped specimen was brought to Gilliard at Kup at some 
elevation about 4,000 ft. Most other New Guinea records are from low 
elevations. 


Henicophaps albifrons albifrons Gray 
White-capped Ground Pigeon 


NATIVE NAME. Daribi: odu.

Soliebeda: 1 9 (23 July 1965). 

NVUIN Ge Le ae eSiien 22 1S el8b, liso. 

BREEDING. One of the two 1964 females had an enlarged ovary, 
but the gonads of the other specimens were small. 


DISCUSSION. ‘The two Karimui females were collected together. 
The Soliabeda female was alone at the top of a tree, and the Karimui 
male was one of a pair on the ground. My only experience with this 
uncommon species in the field was with a solitary individual at 
Soliabeda, flying 10 ft above the ground in partly cut forest with tall 
trees. 

VOICE. ‘The call, delivered from a perch in a tree, is a rapid series 
of “hoo’s” at the rate of 5 per second for 20 sec. The series slightly 
rises in pitch, and has a hollow quality similar to the voice of 
Macropygia nigrirostris or Centropus menbehki.

SPECIES ACCOUNTS 


TAXONOMY. This specimen agrees with cervicalis of southeast- 
ern New Guinea, and differs from nominate nobilis of western New 
Guinea, in the light gray rather than iridescent green-purple nape, 
the dark green rather than dull purple rump, and the deep green 
rather than deep purple underparts. A native-produced specimen from 
the Jimmi Valley on the northern slope of the Eastern Highlands was 
also assigned to cervicalis by Mayr and Gilliard (1954). 

DISCUSSION. ‘This is a rare and local inhabitant of the forested 
hill slopes in the Eastern Highlands, ranging occasionally up to 6,000 
ft. My only field record was of a call heard at 5,100 ft on Mt. Karimui. 


VOICE. A plaintive tremulous, descending whistle lasting 2 sec.

DISCUSSION. Gyldenstolpe mentions individuals of this northern 
Goura semispecies at Nondugl aviary, captured somewhere on the 
northern slopes of the Eastern Highlands. Both semispecies of Goura 
are to be expected only at low elevations.

WEIGHT. 1 $:>210. 1 9: 195. 

WING. “Use l705 i Ox Gs; 

TAXONOMY. Both specimens lack the yellow area in the under- 
wing which is always present in nominate scintillata and often reduced 
or lacking in chloroptera. The underwing coverts are entirely green in 
the Soliabeda male, while in the female they are green for the proxi- 
mal two-thirds and red for the distal third. This character also places 
the Soliabeda birds with chloroptera and differentiates them from 
nominate scintillata, in which the underwing coverts are largely red. 


BREEDING. ‘The testes of the adult male were slightly enlarged. 
DISCUSSION. I encountered no individuals of this lowland spe-

cies besides this pair, and there are no other records from the Eastern 
Highlands. 

The fact that the Soliabeda birds are chloroptera reinforces earlier 
indications that chloroptera, originally described from the southeast- 
ern coast, may extend in the foothills far west of the easternmost 
coastal population of C. s. scintillata (originally described from the 
southwest). ‘Phe localities from which these two races have now been 
recorded are as follows: nominate scintillata, along the southwestern 
coast from ‘Triton Bay (long. 134°E) east to at least the mouth of the 
Fly River (long. 143°E); chloroptera, on the southeastern coast be- 
tween long. 146°E and 148°E, and apparently extending westward in 
the foothills and on the upper reaches of the south coast rivers to 
Soliabeda (upper Purari drainage, long. 145°E), upper Fly River (one 
specimen collected by the Second Archbold Expedition, long. 142°F), 
upper Eilanden River (ca. long. 139°E), and upper Noord River (ca. 
long. 138°E). Both races show much individual variation (e.g., variable 
amounts of yellow in the primaries of chloroptera, of red in the pre- 
dominantly green underwing coverts of chloroptera, and of green in 
the predominantly red underwing coverts of nominate scintillata). 
The Noord River population includes typical chloroptera, typical 
nominate scintillata, and intermediates. Probably hybridization of the 
two races is now occurring after a prolonged break in contact at the 
Fly River, as also seems to be the case with Pstttaculirostris desmarestit. 
‘This would be in keeping with the obvious evolutionary history of the 
genus Chalcopsitta as a superspecies ring in the New Guinea lowlands, 
with contact between populations having been broken and _ reestab- 
lished a number of times. ‘The genus consists of three virtually allo- 
patric semispecies, whose distributions now form an incomplete circle 
(broken in the east between Astrolabe Bay and the Kemp Welch 
River) around the periphery of New Guinea: C. duivenbodei on the 
north coast, C. atra in the far west, and C. scintillata on the south coast 
and Aru Islands. The unique type of C. atra spectabilis (intermediate 
between C. a. insignis and C. s. scintillata) also suggests hybridization 


between former isolates at at least one other point in the ring besides 
the Fly River.

DISCUSSION. ‘The erratic distribution of this lory in the Eastern 
Highlands suggests seasonal migration within New Guinea. On none 
of my visits to the Okapa area (June and August 1964; June 1965; 
June 1966) did I see it in the field. Yet the Fore were familiar with the 
“paila” and said that it was numerous in the rainy season (November 
onward). Several Europeans at Okapa had captive specimens in both 
the orange and the yellow phases, which the Fore had captured as 
nestlings. Similarly, the Daribi were familiar with the Dusky Lory un- 
der the name of “bu-kinikini,’ but I found it rare at Karimui and 
absent at Soliabeda, Bomai, and Mt. Karimui. In the Wahgi Valley, 
Gilliard never encountered it on his two visits (both March or April 
to August), and Gyldenstolpe between August and early November col- 
lected only one specimen (late October). Apparently the Eastern High- 
lands population breeds during the rains and then leaves before the 
onset of the dry season, perhaps retreating to the coastal lowlands. 
Other Eastern Highlands records include Lake Kutubu, the Schrader 
Range, and Kyaka territory. This lory gathers in flocks in flowering 
tees: 

VOICE. A loud, shrill cry quite similar to that of Trichoglossus

STOMACH CONTENTS. Flowers. 

TAXONOMY. ‘This is a variable species, in which each local pop- 
ulation shows some distinct features (Cain, 1955). My specimens are 
closest to intermedius from the Wahgi Valley except that the upper 
belly is less dark green. ‘Vhe race berawensis from western New Guinea 
differs in the more extensive blue on the face and forehead; berauensis 
from the Fly River, in having the dark green of the upper belly spot- 
tier; and micropteryx of southeastern New Guinea, in the paler breast 
and back, browner nape and cheeks, and narrower green edges to the 
red of the breast. T. h. caeruleiceps of the lower Fly River is very 
distinct in its much darker green belly, pronounced orange wash on 
the abdomen, reduced green edges to the red of the breast, and more 
extensive blue on the forehead and sides of the head. ‘The material of 
Gyldenstolpe and Gilliard from the Wahgi Valley was also assigned to 
intermedius, while Schodde and Hitchcock placed one specimen from 
Lake Kutubu with micropteryx. 

BREEDING. The testes of both males collected at Karimui in

1964 were enlarged. In 1965 the gonads were enlarged only in a 
Soliabeda male. According to the Fore this lory, like many others, 
breeds at Okapa during the rainy season. 

DISCUSSION. I encountered Trichoglossus haematodus, one of 
the most widespread and conspicuous lories in the Eastern Highlands, 
at all my collecting stations except Mt. Michael, up to 4,500-5,000 ft 
in primary forest and up to 6,500 ft in the casuarina groves and trees 
of villages and open country. It usually occurs in small, noisy groups 
of up to half a dozen individuals perched in the middlestory and 
canopy of trees or calling loudly in flight. Unlike Pseudeos fuscata, to 
which it is otherwise rather similar in voice and habits, 7. haematodus 
does not leave the Eastern Highlands during the dry season. 

Pairs of birds that were perched facing each other 1 ft apart dis- 
played by opening and rapidly fluttering the wings to reveal the 
strikingly colored pattern of the underwing. Many species of lories 
have patterned underwings that may function in species-specific dis- 
plays. 

Terborgh’s observations on feeding trees indicate that the main 
food source of T. haemotodus is flowers and that it takes fruit less fre- 
quently. At Karimui it was the second commonest parrot in flowering 
trees, accounting for about 10% of the bird-usage, and it actually fed 
on the blossoms by biting off the receptacles and allowing the petals 
to fall to the ground. However, ‘Verborgh also encountered an unusual 
relation between this species and honeyeaters in Ficus trees at Karimui 
and Miarosa. ‘The fruits of these cus were about 8 cm long and 4 
cm in diameter and protected by a thick, woody pericarp which pre- 
cluded any direct assault on the soft pulp inside. Underneath the trees 
were lying fallen fruits with neatly cut holes about 1 cm in diameter 
at the blossom ends. Observation of the feeding birds showed that 
these holes were being made by Trichoglossus haematodus and an- 
other parrot, Psittaculirostris desmarestti, which tossed aside chips 
with a shake of their heads and gained access to the pulp within five 
minutes. Not even these parrots, though, could penetrate the side walls 
of the pericarp, and they always had to abandon the fruit with most 
of the pulp remaining because of their short bills. Honeyeaters such 
as Melilestes megarhynchus, Melidectes torquatus, Meliphaga flavi- 
venter, and several other species of Meliphaga then inserted their 
long, delicate bills, which would have been useless for opening the 
fruit, and ate more of the pulp. Initially, when most of the fruits were 
still unopened, 99%, of the bird-usage in these Ficus trees was by 
Trichoglossus and Psittaculirostris, and 1% by honeyeaters, Later, 
when most of the fruits had been opened and the parrots had ob- 
tained as much pulp as their bills could reach, honeyeaters accounted 
for up to 93% of the usage, and parrots only for 7%. 

VOICE. A high, short, very grating shriek, louder than that of

Psitteuteles goldiet (Sharpe) 
Red-capped Streaked Lory 
NATIVE NAME. Fore: yani. 


DISCUSSION. This is the least common of the midmontane lories, 
known from eight scattered localities in the Eastern Highlands be- 
tween about 5,500 and 8,500 ft. My only field observation was of a 
noisy flock flying over the forest at 6,900 ft above Miarosa. According 
to the Fore it breeds at Okapa during the rainy season as do other 
lories, and several caged birds which had been brought in as nestlings 
were kept as pets by Europeans at Okapa. In Kyaka territory Bulmer 
commonly noted flocks of up to 40 in December and January but only 
occasionally saw the species during the rest of the year, implying 
local migration. 


Domicella lory somu Diamond and D. I. erythrothorax (Salvadori) 


Western Black-capped Lory 


NATIVE NAMES. Fore: korié. Gimi: korié. Daribi: sému. 

SPECIMENS EXAMINED. D. Il. somu: Karimui, 1 4, 2 9; Bomai, 2 4, 2 9; 
Soliabeda, 2 g, 2 9; Mt. Karimui Zone 1, 1 ¢ (7 July-11 Aug. 1965). D. 1. 
erythrothorax: Sena River, 1 ¢ (26 July 1964). 

WING. D. lI. erythrothorax; 1 8, 167 (see Diamond, 1967a, for weights and 
wing measurements of D. 1. som). 

TAXONOMY. As discussed elsewhere (Diamond, 1967a), the race 
somu, with a restricted range in the Karimui Basin and Purari River 
drainage, is unique in lacking the neck band present in all other races 
of D. lory but absent in D. hypoinochrous. Surprisingly, the single 
specimen which ‘Verborgh and I collected 15 miles east of Karimui at 
the Sena River, on the slopes of the mountain walls ringing the Kari- 
mui Basin but still within the basin, definitely belongs to the south- 
eastern New Guinea race erythrothorax because of the presence of the 
neck band (and slightly larger size). Schodde and Hitchcock assigned 
the Kutubu population to D. 1. rubiensis, but their description implies 
that it actually belongs to D. 1. somu, since they mention the absence 
of the neck band. 

BREEDING. ‘The gonads were small in 11 specimens, slightly en- 
larged in the two others, suggesting that breeding was suspended in 
the dry season, as with other lories. 

DISCUSSION. Domicella lory is generally distributed along the 
southern edge of the Eastern Highlands up to about 4,500 ft, being 
uncommon above 3,000 ft but numerous at Soliabeda (2,000 ft). In 
virgin forest the lories Domicella lory, Trichoglossus haematodus, and 


144 


SPECIES ACCOUNTS 


Pseudeos ftiscata all extend up to nearly the same altitude (the latter 
two consistently several hundred feet higher), but Domicella lory has 
failed entirely to follow the other two species in colonizing the man- 
made second-growth habitats of the Eastern Highlands at 5,000-6,500 
ft. The social behavior is also different. Trichoglossus haematodus and 
Pseudeos fuscata are often seen in small flocks, both when in flight 
and when in feeding trees. All my sightings of Domicella lory in flight 
were of individuals or pairs, and the largest number that I saw to- 
gether in a feeding tree was three. ‘To judge from the trees it fre- 
quents, it feeds principally on flowers, secondarily on fruits. 


VOICE. More varied and more musical than that of Trichoglossus 
haematodus or of Pseudeos fuscata. The commonest vocalization con- 
sists of two identical squeals in immediate succession, with a quality as 
of sleigh-bells when heard in the distance; this double squeal cannot 
be confused with the voice of other New Guinea parrots. In addition, 
a variety of high piercing squeaks and loud whistles may be emitted, 
particularly when the birds are perched. 


| Domiceta hypoinochroa devittatus (Hartert) | 
Eastern Black-capped Lory 


DISCUSSION. ‘This species has never been found west of Hall 
Sound in southeastern New Guinea. Mayr and Gilliard (1954) list it 
from the Eastern Highlands on the basis of a captive bird photo- 
graphed by Gilliard at Kup and said to have been caught south of the 
Kubor Range. ‘This captive was probably a misidentified individual of 
Domicella lory somu, the common Domicella of the Eastern High- 
lands. At the time when Gilliard examined the Kup pet in 1952, the 
race D. 1. somu was still unknown, and the best way of distinguishing 
D. hypoinochroa and D. lory was thought to be the neck band present 
in the former and absent in the latter. However, somu lacks the neck 
band, and must be distinguished from D. hypoinochroa by subtler 
points easily overlooked or invisible in a photograph.

SPECIES ACCOUNTS 


thina of western New Guinea and differ from stellae of southeastern 
New Guinea in that the longest rectrices are yellow-green rather than 
reddish yellow, and in that the red of the longest uppertail coverts is 
tipped with green. 

BREEDING. The Mt. Karimui male and female were a pair with 
enlarged gonads. 


DISCUSSION. Charmosyna papou is a regular inhabitant of the 
forest interior from 5,500 to about 9,000 ft and has turned up at vir- 
tually all collecting stations in this habitat. It is locally common, but 
its abundance depends upon the presence of the flowering trees on 
which it feeds. Unlike some other lories, C. papou remains within the 
forest, and I never saw it in open country. 


The altitudinal range of C. papow lies above those of all its con- 
geners, except that C. pulchella occasionally overlaps C. papou. C. 
papow shares its range with four other lories, but these five high- 
altitude lories sort out largely on the basis of size: Oreopsittacus arfaki, 
ca. 20 g; Neopsittacus pullicauda, 38 g; Neopsittacus musschenbroeku, 
50 g; Psitteuteles goldier, 60 g; Charmosyna papou, 85 g. 

VOICE. A shrill, somewhat grating cry, more grating than that 
of Oreopsittacus arfaki or Neopsittacus pullicauda but much weaker 
than that of Trichoglosslsus haematodus. A loud wing beat which I 
heard frequently on Mt. Karimui was attributed to this species by 
the Fore:

TAXONOMY. The specimens are indistinguishable from bella 
of southeastern New Guinea and ‘Telefolmin. 


BREEDING. ‘The testes were slightly enlarged. 


DISCUSSION. ‘This lory is sparsely distributed in hill forest along 
the slopes of the Eastern Highlands between about 2,000 and 5,800 ft. 
Its altitudinal range lies largely but not entirely below that of C. 
papou. Elsewhere in New Guinea its range lies entirely above that of 
C. placentis, but in the Karimui area, where C. placentis extended up 
to 4,750 ft, C. pulchella and C. placentis overlapped considerably and 
fed in the same flowering trees at the Sena River and on Mt. Karimui. 

C. pulchella is one of several hill forest species with a discontinuous 
altitudinal range at Karimui because the tropical flat basin floor di- 
vides its normal range on the hill slopes (p. 55). On Mt. Karimui all

the specimens and observations of C. pulchella fell between 4,400 and 
5,290 ft. The species was also present at the Sena River, (4,500 ft) on 
the eastern wall of the Karimui Basin. I never encountered it on the 
flat basin floor (3,650 ft), and Yudo natives confirmed that it was ab- 
sent there and to be found only on the mountain. A few individuals 
were seen again when we went down to Soliabeda (2,000 ft) beyond the 
basin walls. 

Like other lories, C. pulchella congregates noisily in flowering trees. 
Like C. papou and unlike C. placentis or Trichoglossus haematodus, 
it remains within the forest and rarely ventures into open country. 

VOICE. A short note similar to that of C. placentis but sweeter, 
less shrill or staccato. 


Charmosyna wilhelminae (Meyer)

Kei Islands, and Aru Islands (the patch is much larger in ornata and 
absent in swbplacens of southeastern New Guinea). My females aver- 
age slightly darker above, and my males deeper red on the flanks, 
than the comparative material of placentis, in line with the general

DISCUSSION. ‘This species has hitherto been considered a char- 
acteristic bird of the New Guinea lowlands at elevations near sea level. 
Its presence in abundance at Karimui (3,650 ft) may constitute an alti- 
tudinal record. It remained numerous on the lower slopes of the basin 
walls and finally disappeared at 4,750 ft on Mt. Karimui. At Soliabeda 
(2,000 ft) it was even more abundant. There are no other Eastern 
Highlands records, and its distribution or area of abundance in the 
Eastern Highlands may prove to be confined to the Karimui area. 

C. placentis congregated to feed in flowering trees, where it was the 
most numerous species in the Karimui area and provided from 15% 
to as much as 65% of the bird-usage. We had no records of it in the 
many fruiting trees kept under observation. In the flowering trees it 
distributed itself uniformly throughout the crown. At any time a given 
tree might hold up to 25 individuals of C. placentis, which came and 
went in groups of two to 10, kept up an incessant chatter, and often 
paused from feeding to chase each other. 

VOICE. A single short note “tsss’’—crisp, shrill, high, and staccato, 
and considerably less substantial than the notes of Neopsittacus mus- 
schenbroeku, Trichoglossus haematodus, or Pseudeos fuscata.

STOMACH CONTENTS. Flower paste. 

TAXONOMY. Eastern Highlands birds lack the red abdominal 


spot present in major and nominate arfaki. 

BREEDING. ‘The testes were enlarged in birds from Mt. Karimui. 

DISCUSSION. ‘This small, high-altitude lory is characteristic of 
moss forest, and its vertical distribution on a given mountain seems 
to correlate with the distribution of this vegetational type. On Mt. 
Karimui, where the cloud level is lower than in most other parts of 
the Eastern Highlands, Oreopsittacus descended to 5,600 ft. On Mt. 
Michael, where the trees were heavily mossed only above 8,700 ft, 
Oreopsittacus was found only above this altitude and occurred up to 
about 10,500 ft in the moss forest. At Okapa I collected up to 7,500 ft 
and found neither heavy moss nor this parrot, but the Fore were 
familiar with the “tushuke” and said that it lived somewhere on top. It 
occurs in flocks of two to six and frequents flowering trees. 

VOICE. A short, weak, unvoiced, repeated note “ts,” weaker than 
that of other montane lories and more suggestive of a warbler than of 


a parrot.

NATIVE NAMES. Fore: kasa. ’ Gimi: kasa. 

SPECIMENS EXAMINED. Awande: 7 ¢,5 9 (14-20 June 1965). Mengino: 1

WEIGHT. 6 @:-50-62 G22). 7 Ox 40-55 (00 4 I). 

WING. 8 4: 109-117 (13 +53). 7 9: 111-116 (113 = 2). 

STOMACH CONTENTS. Dry and granular flower remains, 

BREEDING. All specimens, except one Awande female, had small 
gonads. According to the Fore, the “kasa” breeds in the rainy season. 

DISCUSSION. Neopsittacus musschenbroeku is widespread at 
about 5,000-8,500 ft throughout the Eastern Highlands. It is one of 
the few midmontane forest birds that have profited greatly from hu- 
man activities, most of the other species in man-made habitats in the 
Eastern Highlands being originally lowland birds. For example, it 
was numerous in partly cut forest around Okapa, Lufa, and Mengino, 
and was the commonest parrot at Miarosa village (5,800 ft), congre- 
gating in casuarina stands along the gardens and roads in flocks of 
up to 50. On the other hand, it seems to require at least the close 
proximity of forest and is absent in areas (such as Goroka) where the 
forest has been largely or completely eliminated for miles around to 
leave just isolated groves. N. musschenbroekw is invariably seen in 
pairs or larger groups, not as individuals. 

VOICE. A shrill! “ss”, “ks’, or “ts”, somewhat staccato and hoarse, 
and moderately high in pitch. In comparison with the notes of other 
lories that may be found in its altitudinal range, the note of N. 
musschenbroeki is harsher, shorter, and more grating than that of 
N. pullicauda, more staccato and considerably stronger than that of 
Oreopsittacus arfaki, and less harsh and somewhat weaker than the 
notes of Pseudeos fuscata or Trichoglossus haematodus. The note is 
heard frequently whether the birds are perched or in flight. 


Neopsittacus pullicauda pullicauda Hartert 
Orange-billed Mountain Lory 

SPECIMENS EXAMINED. Mt. Michael: 1 ¢ (5 July 1964). 

WING. 100. 

STOMACH CONTENTS. Dry and granular flower remains. This species and 
N. musschenbroekii may actually eat flowers, whereas Oreopsittacus arfaki and 
Charmosyna papou, whose stomachs contain soft paste, perhaps only take nectar. 

BREEDING. ‘The gonads were very small. 

DISCUSSION. ‘To my surprise, the specimen was caught in a mist- 
net a few feet above the ground in tall forest on level ground at 8,000 
ft (Neopsittacus generally stays in the canopy). 

This is the high-altitude Neopsittacus species, living in moss forest

SPECIES ACCOUNTS 


throughout the Eastern Highlands at about 7,500-10,000 ft. Its alti- 
tudinal range overlaps that of N. musschenbroekii by 500 or 1,000 ft, 
and in the intermediate zone both species can be found in the same 
flowering tree. This overlap may be made possible by the fact that 
N. musschenbroeku is about 40% heavier than N. pullicauda. ‘The 
main plumage differences between these two sibling species are that 
N. musschenbroekii has a yellow bill, yellow undertail, and light shaft 
streaks on the crown, while N. pullicauda has a more orange bill, olive 
undertail, and lacks light shaft streaks on the crown. 


VOICE. A gentle sibilant note, harsher than that of Oreopsittacus 


arfaki but weaker and less shrill than that of Neopsittacus musschen- 
broekit. 


Psittaculirostris desmarestti cervicalis (Salvadori and D’Albertis)

TAXONOMY. When compared with specimens of cervicalis (the 
southeastern New Guinea race) from the Brown River, Kumusi River, 
Hydrographer Mountains, and Holnicote Bay, Karimui specimens dif- 
fer only in that the throat and cheeks are paler, more yellow and less 
orange, and in that the ear coverts are even deeper red-orange. From 
Fly River material collected by the Second Archbold Expedition and 
classified as godmani  cervicalis (Rand, 1942a), Karimui specimens 
differ in that the breast band is deeper blue and in that the ear coverts 
are darker and deeper orange, but they agree in the color of the throat 
and cheeks. ‘The Karimui population is thus intermediate between 
southeastern New Guinea birds and the variable Fly River popula- 
tion but is nearer the former. 

BREEDING. ‘The gonads of the 1964 male were considerably en- 
larged, but those of the 1965 males were only slightly enlarged. 

DISCUSSION. ‘The three semispecies of genus Psittaculirostris 
constitute a superspecies ring in the lowlands around the periphery of 
New Guinea. As discussed by Rothschild (1920), Fly River birds ap- 
pear to be hybrids between the distinct races P. d. godmani of the 
southwest and P. d. cervicalis of the southeast. Evidently the Fly River 
was one of four major points (the other three being Huon Gulf, Hum- 
boldt Bay, and Geelvink Bay) where distribution in the Psittaculiros- 
tris ring was formerly broken, but reestablishment of contact at the 
Fly River between populations on either side of the break evidently 
occurred before differences had developed to the point of reproductive

isolation. The evolutionary history of the genus Chalcopsitta must 
have been similar. 

The presence at Karimui (3,250-4,200 ft) constitutes an altitudinal 
record for this lowland genus, and other records of P. desmarestti tor 
the Eastern Highlands are lacking. As in the case of several other low- 
land species, so for P. desmarestii the Karimui population represents 
an isolated island of distribution, since I did not find the species at 
Soliabeda (2,000 ft) immediately to the south of the Karimui Basin, 
nor did Schodde and Hitchcock report it from Lake Kutubu (2,450 ft). 
At Karimui this parrot was uncommon, was seen in groups of two to 
six, and occurred much more often in fruit trees than in flowering 
trees, where it might be seen at any height from the lowest to the high- 
est branches. ‘Together with Trichoglossus haematodus it cut holes 
with its heavy bill through the woody pericarp of Ficus fruits, most 
of whose pulp was then eaten out by long-billed honeyeaters (see 
p. 143). One pair was seen coming out of a hole in a tree. 

VOICE. A high, thin, downslurred note quite unlike that of the 
other parrots in feeding trees at Karimui. 


Psittaculirostris edwardsit (Oustalet) 
Edward's Fig Parrot 


DISCUSSION. Mayr and Gilliard recorded two specimens col- 
lected by N. B. Blood in the Jimmi River region, and another speci- 
men at Nondugl aviary from unknown locality. Gyldenstolpe men- 
tioned four further Nondugl aviary birds originating from the Jimmi 
River. This is the Pstttaculirostris form of northeastern New Guinea 
and presumably confined in the Eastern Highlands to low elevations 
on the northern slopes. 


VOICE. A very short, metallic note “ks” with a sharp attack, as 
the sound of coins falling on concrete. 


Opopsitta gulielmitertit swavissima (Sclater) 
King William’s Fig Parrot 

SPECIMENS EXAMINED. Bomai: 2 ¢ (a and b),1 9 (6 July 1965). 

WEIGHT. 2 4: 33 (a), 27 (b). 1 9: 33. 

WING. 2 4: 77 (a), 70 (b). 1 9: 79. 

TAXONOMY. All three specimens agree with swavisstma of south- 
eastern New Guinea in having the forehead blue, whereas it is brown 
in fuscifrons, the race of southwestern New Guinea from the Fly River 
westward. The inner edges of the innermost primaries are yellow, a 
character shared by both these races and by melanogenia of the Aru 
Islands. ‘The small male labelled ‘“b” resembles the adult female in

plumage and is presumably a second-year bird (Mayr and Rand, 1037) 

DISCUSSION. In addition to collecting this lowland species at 
Bomai, I observed it at Karimui and Soliabeda as well, but there are 
no other Eastern Highlands records outside of the Karimui area. It 
was uncommon and was seen in groups of two to four, containing birds 
of both sexes. We had a few observations of it in flowering trees. 


VOICE. ‘There are two call notes: a short, unmusical, staccato 
ks”; and a short, more musical, less staccato “‘ts’’ with a sweet quality. 
Both notes are less sharp, shrill, or grating than those of Charmosyna 
placentis. 


Opopsitta diophthalma festetichi (Madarasz) 
‘T'wo-eyed Fig Parrot 


NATIVE NAMES. Fore: ninti or isoateo. 

SPECIMENS EXAMINED. Okasa: 1 9 (24 June 1965). 

WEIGHT. 56. 

WING. 94. 

TAXONOMY. ‘The races of this parrot have been reviewed re- 
cently by Forshaw (1967). I reassessed the New Guinea mainland and 
Aru Islands populations in the light of 51 specimens at the American 
Museum of Natural History: 11 from southeastern New Guinea Chee 
> 9, limm. ¢), four fom the Kasterm Fhehlands (1 45 2 5 lam: 
@), one ( g ) from the Huon Peninsula, one (¢ ) from the Ramu River, 
two (¢) from Astrolabe Bay, five from the North Coastal Range (2 4, 
3 @), 19 from western New Guinea and the western Papuan islands 
(lO"3, 7 2; 2mm. ¢), ones) trom the Bly Raver, and seven <, 
2 ¢,2imm. ¢) from the Aru Islands. ‘The material from eastern and 
northeastern New Guinea (Eastern Highlands, Huon Peninsula, North 
Coastal Range, Huon Peninsula, Ramu River, Astrolabe Bay) differs 
from the southestern and western populations in having a wider yellow 
band across the crown of the male and in that the backs of the females 
are slightly darker. ‘The name festetichi (type locality Astrolable Bay) 
is available for this eastern and northeastern population to distinguish 
it from nominate diophthalma (type locality ‘Triton Bay, western New 
Guinea). In both the male and female characters the southeastern 
population is not separable from the western population and is sep- 
arable from festetichi, so that the race coccineifrons from southeastern 
New Guinea must be considered synonymous with nominate dioph- 
thalma (not with festetichi, as Forshaw had suspected). Neither For- 
shaw nor I could detect the alleged variation in the depth of the red 
color of the forehead and cheeks, sometimes cited as a racial character. 
In the race aruensis the yellow crown band of the male is either lack- 
ing (Aru Islands) or very narrow (Fly River), and the female of aru- 
ensis is quite distinct.

SPECIES ACCOUNTS 


BREEDING. ‘The Okasa female was one of a pair coming out of 
a hole in a tree and may have been preparing to breed, as suggested 
by the enlargement of the ovary. 

DISCUSSION. ‘This fig parrot has a very spotty distribution at 
lower elevations (i.e., up to about 5,000 ft), and apparently lives in 
second-growth trees, in partly cut forest, and at the forest edge rather 
than in primary forest. In 1964 ‘Terborgh saw the species several times 
at Okasa (3,500-4,250 ft) in stranglers bearing fruits about 5 mm in 
diameter. Gilliard reported it as “not uncommon up to 5,000 feet in 
the riverine forests near Kup” (Mayr and Gilliard, 1954, p. 339); Gyl- 
denstolpe collected 10 specimens near Nondugl but met it nowhere 
else; Bulmer obtained one specimen about 6,000 ft in Kyaka territory; 
and there are sight observations from Baiyer Valley (N.G.B.S. News- 
letter, No. 54, p. 1, June 1970). Birds that I saw were usually solitary, 
and perched at the tops of dead trees or else probed bark while hang- 
ing upside down. 

VOICE. A sharp, sweet, somewhat metallic “ks,” similar to the 
call of Psittaculirostris edwardsit but weaker and with a less sharp 
attack. 


Micropsitta bruijni bruijni Salvadori 
Mountain Pygmy Parrot 


This locally distributed species of mountain forest is known in the 
Eastern Highlands from one specimen taken at 7,500 ft in the Kubor 
Mountains by Gilliard, six taken on the Schraderberg by Burgers, one 
collected at 6,700 ft at Minj by N. B. Blood, sightings by Bulmer in 
the Jimmi Valley, and sightings at 5,500 ft in the Hagen area (N.G.B.S. 
Newsletter, No. 54, p. 1, June 1970). It works along and around 
branches in nuthatch-like fashion. The very similar Micropsitta pusio 
may turn up at lower elevations. 


Probosciger aterrimus goliath (Kuhl) 


Palm Cockatoo 

NATIVE NAMES. South Fore: pakitéra. Daribi: boriau. 

SPECIMENS EXAMINED. Okasa: 1 ? (26 June 1965). 

WING. 390. 

TAXONOMY. From the large size I presume that this specimen 
belongs to the race goliath, inhabiting the foothills of southern New 
Guinea, rather than to nominate aterrimus, an Australian race which 
reaches the coastal lowlands of southern New Guinea. Schodde and 
Hitchcock also identified the Lake Kutubu population as goliath. The 
race stenolophus of northern New Guinea has much narrower crown 
feathers.

SPECIES ACCOUNTS 


DISCUSSION. ‘The specimen was collected while eating fruit at 
the top of a tree in the Okasa forest at about 4,200 ft. According to 
Fore natives living near this forest, the “pakitora” is quite uncommon 
there. My Daribi assistants also knew the “boriai’” but said that it 
appears only very infrequently at Karimui (3,650 ft). 

VOICE. A rapid series of alternate upslurs and downslurs “whik- 
whik-whik .. .” at a rate of 4 per second. Occasionally, a melodious, 
whistled, jumbled call with a quality similar to Domicella lory. 


Cacatua galerita triton ‘VYemminck 


Sulphur-crested Cockatoo 

NATIVE NAMES. Fore: wai. Gimi: é6de. Daribi: na4ra. Pidgin English: koki. 

DISCUSSION. In the areas of the Eastern Highlands which I vis- 
ited and which are still little disturbed by man, C. galerita is a ubiqui- 
tous and conspicuous inhabitant of primary forest up to about 5,000 
ft, locally (Awande, Mt. Michael, Mt. Karimui) up to 7,000 ft, and 
was present at all my Eastern Highlands collecting stations. In areas 
with moderate human population densities, particularly those where 
shotguns are permitted, this cockatoo tends to disappear because its 
yellow crest plumes are prized for decoration. Gyldenstolpe and Gilli- 
ard did not meet cockatoos in the central parts of the Eastern High- 
lands in the wild state. ‘Their studies were confined to altitudes above 
4,000 ft, largely above 5,000 ft, but at these elevations cockatoos should 
merely be uncommon rather than absent, and I suspect that the species 
has already been extermniated by the higher human population densi- 
ties in these areas. 

The Sulphur-crested Cockatoo was usually seen in small groups of 
from a few to a dozen individuals. It is most conspicuous when soar- 
ing, somewhat hawk-like, high over the forest and calling loudly. ‘This 
behavior seems to constitute a social display, for a few birds will land 
screaming in a tree, to be followed by several others which can be 
seen and heard as they come flying in from a mile away. A perched 
bird that is alarmed bends its head and sways, raising its yellow crest, 
to observe a human intruder from various angles. 

VOICE. The call is the loudest of any New Guinea bird: a fa- 
miliar, ear-splitting, harsh scream, delivered perched or in flight. A 
very different and infrequent vocalization, given only when perched, 
consists of a virtually continuous sound which goes on for several 
minutes, interrupted briefly every 114 sec while the bird catches its 
breath. The pitch is nearly constant but rises slightly before each 
catching of breath. The sound is not loud and is difficult to localize 
if one does not happen to see the singer. ‘The quality is totally un- 
musical, somewhat rasping, invites confusion with an insect, but most 
closely resembles the voice of a dog whose vocal cords have been dam- 


aged.

SPECIES ACCOUNTS 
Psittrichas fulgidus (Lesson) 
Vulturine Parrot 

NATIVE NAMES. Fore, Gimi, and Daribi: kabare. 

DISCUSSION. My sole field observation of this remarkable parrot 
in the Eastern Highlands came at Soliabeda, in an area of very low 
human population density, where one bird perched at the top of a tall 
tree in a native garden and then flew off. ‘he distinctive flight con- 
sists of alternate rapid flaps and soaring, reminiscent of the Black 
Vulture Coragyps atratus of the New World. ‘To judge from native 
reports, it is present but rare at lower elevations in Fore, Gimi, Daribi, 
and ‘Tudawhe areas. Schodde and Hitchcock saw groups of up to 20 
at Lake Kutubu. 

The red feathers of the “kabare” are prized by natives far more than 
the plumage of any other bird, including any bird of paradise. Even 
in a poor area like Karimui, a Psittrichas commanded the relatively 
enormous sum of twenty dollars, equal to the price of a large pig and 
not much less than the price of a wife. Despite this popularity I saw 
or heard of only three captive Psittrichas in the Karimui area, an in- 
dication of its rareness even in areas with sparse human population. 
This is one of the few montane species whose existence is threatened 
directly (i.e., as opposed to being threatened indirectly through de- 
struction of habitat) by man. 

VOICE. Very harsh, rasping, drawn-out screams. Often the screams 
are in pairs, the first at constant pitch and hoarse, the second up- 
slurred, nasal, and squeaky as the sound of a rusty gate. 


Larius roratus pectoralis (Muller) 
Red-sided Eclectus Parrot 


NATIVE NAMES. Gimi: néra. Daribi: anari (male), tégali (female). 

SPECIMENS EXAMINED. Karimui: 1 ¢ (12 Aug. 1964). Mt. Karimui Zone 1: 
1 g (11 Aug. 1965). 

WING. 2 4: 256, 263. 

BREEDING. ‘The testes of the Mt. Karimui specimen were large, 
while those of the Karimui bird were very small. 


DISCUSSION. ‘The Red-sided Eclectus Parrot was found up to 
4,800 ft throughout the Karimui area, where my census figures showed 
that it was consistently about one-third as numerous as Cacatua 
galerita. In the lowlands this species is more numerous and sometimes 
assembles in considerable numbers, circling conspicuously high over- 
head at sunset like the Nestor parrots of New Zealand. However, in 
the Karimui area it was invariably solitary. It is probably widespread 
at the lower elevations in the Eastern Highlands, since my Gimi as- 
sistants were familiar with it and my Awande assistants knew it from 
low elevations in Fore territory. It was found common at Lake Kutubu

(2,450 ft) by Schodde and Hitchcock and up to at least 5,000 ft in 
Kyaka territory by Bulmer. 

VOICE. A loud harsh scream, quite similar to that of Cacatua 
galerita, but with a more croaking quality and less deafening. 


Geoffroyus geoffroyi aruensis (Gray) 
Red-cheeked Parrot 


SPECIMENS EXAMINED. Soliabeda: 1 9 (22 July 1965). 

WEIGHT. | 169. 

WING. 155. 

TAXONOMY. The single specimen agrees with aruensis, e.g., in 
that the rump is green rather than red. 

DISCUSSION. At Soliabeda (2,000 ft) this was the fourth com- 
monest parrot, and Schodde and Hitchcock found it widespread at 
Lake Kutubu (2,450 ft), but I saw it only a few times at Karimui 
(3,650 ft). This is a lowland species with an altitudinal range only 
marginally overlapping that of its congener G. simplex, which was 
absent at Soliabeda but common at Karimui and higher elevations. 
G. geoffroyi occurred singly or in groups of a few birds, and most often 
attracted attention when calling loudly in flight. 

VOICE. A series of identical notes repeated at the rate of two to 
three per second for 5 to 10 sec. The notes are high and fairly loud, 
and have a bright, piercing, ringing quality as of a metal surface being 
struck. Each note is upslurred, virtually disyllabic. Only two other 
species have calls with which the call of Geoffroyus geoffroy: can be 
confused. At a great distance and when not heard clearly, the call of 
G. simplex may sound similar. Some calls of the drongo Dicrurus hot- 
tentottus, which also consist of a series of ringing, metallic, disyllabic 
notes, are very similar and at times virtually indistinguishable. With 
practice the drongo calls can usually be distinguished by the facts that 
the series in the drongo usually consists of fewer notes; that the 
drongo’s notes are sometimes downslurred, whereas they are always 
upslurred in G. geoffroyi in the Eastern Highlands (though not in 
other parts of New Guinea); and in that the call is usually delivered 
in flight by G. geoffroyi but when perched by the drongo. ‘Vhe quality 
of the voice of G. geoffroyi shows considerable geographical variation. 


Geoffroyus simplex subsp. 
Blue-collared Parrot 
NATIVE NAMES. Fore: k’ri-k’ro. Daribi: sibunane.

DISCUSSION. Although I found this parrot widespread and fairly

common throughout the Eastern Highlands at 3,000-6,500 fi 1t 1680 
incredibly shy that a specimen with locality data has yet to be col- 
lected. Usually I saw it in flocks flying overhead at a great height and 
calling, and neither I nor my native assistants were able to approach it 
more closely than 200 feet when it was perched in flowering trees, with- 
out its panicking and bolting. It is said to eat acorns of the oak Casta- 
nopsis. A nestling reared in captivity learned to speak a few words. 

VOICE. In pattern, similar to the voice of G. geoffroyi, 1.e., a series 
of piercing high notes delivered at the rate of about two per second. 
The successive notes are at nearly, but not exactly, the same pitch and 
vary slightly in quality, whereas successive notes of G. geoffroyi are 
identical. The sounds are well represented by a repetition of the Fore 
name: k’ri-k’ro-k’ri-k’vo- etc. As usually heard, i.e., at a great height, 
the quality is appealing and somewhat musical, as of sleigh-bells in 
the distance or of a rusty gate swinging back and forth. Under these 
circumstances confusion with the voice of G. geoffroyi is possible. ‘The 
charm of the call disappears when heard nearby, and it becomes loud, 
harsh, piercing, and unmusical.

WIENG. 84,0195. 2) 0 2190) 97. 

TAXONOMY. In the narrowness of the blue band on the upper 
back, the two adult males agree with callopterus, the form of central 
New Guinea, rather than with nominate chloropterus, the southeast- 
ern New Guinea race. ‘The band is slightly broader in the male from 
Awande than in the male from Karimui (100 miles west of Awande), 
possibly suggesting an approach to nominate chloropterus. 

BREEDING. ‘The gonads were enlarged in the Okasa specimens, 
small in Karimui specimens. 

DISCUSSION. ‘The Papuan King Parrot was present in low num- 
bers at all my forested collecting localities below 6,500 ft in the south- 
ern parts of the Eastern Highlands and probably occurs down to the 
foot of the hills. Apart from a Nondugl aviary bird and a pet bird of 
uncertain origin recorded by Gilliard and Gyldenstolpe, and probably 
taken at lower elevations in the Jimmi Valley, records of this forest 
species from the central parts of the Eastern Highlands seem to be 
lacking, possibly because of the extensive deforestation there below 
6,500 ft. It is virtually confined to the shaded forest interior, occurs 
singly or in groups of two or three, remains unobtrusively in the lower 
branches and middlestory, moves deliberately, and flies only short dis-

loud, hoarse, harsh, very short and staccato note. (b) ‘(he commoner 
call is a series of five or six similar notes at 11% sec intervals, at medium 
pitch, with a somewhat piercing quality, and each note being slightly

Niche Differences in the Genus Psittacella 


The four species of this genus apparently sort out ecologically in a 
simple fashion. ‘There are two large species, P. brehmii and P. picta, 
and two small species, P. madaraszi and P. modesta. At a given altitude 
one may find one large species and one small species, but the two large 
species have nearly mutually exclusive altitudinal ranges, as do the 
two small species. Details of plumage and distribution suggest that, 
of the three speciations in this genus, the first was the split between a 
large form and a small form, the second produced the second large 
species, and the most recent produced the second small species (Fig. 
16).

material is closest to the southeastern New Guinea race pallida. ‘Vhe 
Mt. Karimui male has the head and upper breast darker than in any 
other specimen available for comparison, but this character is sub- 
ject to postmortem fading (Rand, 1942b, p. 452) and varies individ- 
ually. The western race intermixta differs in that it is considerably 
larger, while harterti females (Huon Peninsula) have a slightly paler 
head and less extensive barring on the breast and flanks. ‘The race 
buergersi from the Schraderberg is probably synonymous with pallida 
(Gilliard and LeCroy, 1968). 

BREEDING. ‘The testes of the Mt. Karimui male were slightly en- 
larged. . 

DISCUSSION. Psittacella brehmi is an uncommon and solitary 
but widespread inhabitant of montane forest between about 5,300 ft 
and 9,000 ft, and has been encountered sparingly by most collectors 
at most localities within this zone (the claim of Gyldenstolpe, 1955, 
p. 57, that “it inhabited grassland and shrub country” appears unique). 
The individuals that I saw were 10 to 50 ft above the ground, slowly 
walked along a branch supporting themselves by the legs and bill with- 
out using the wings, and periodically stopped to bite at something. 
‘They spent at least 10 minutes in the same tree and often remained 
motionless for several minutes. 

Records from the Eastern Highlands and other parts of New Guinea 
indicate that the altitudinal ranges of P. brehmii and its similar-sized 
high-altitude relative P. picta are nearly mutually exclusive, with the 
transition altitude varying locally between 8,000 and 10,000 ft. On the

Huon Peninsula, where P. picta is absent, P. brehmii may extend up 
to 3,800 meters (= 12,500 ft), as suggested by altitudes on labels of 
specimens collected by Keysser and examined in the American Mu- 
seum of Natural History. In plumage P. brehmii and P. picta are more 
similar to each other than to their smaller relatives P. modesta and 
P. madaraszi but the two large species differ more from each other 
than do the two small species, suggesting that the former speciation 
occurred earlier. In addition, the races of P. picta are quite distinct, 
also indicating that it is a relatively old species. 

VOICE. P. brehmii is generally silent, but on a single occasion I 
saw it give a two-note call (Fig. 17). The first note was short and 
harsh, and was followed at a 1/4-sec interval by a nasal note which first 
rose and then fell in pitch.

TAXONOMY. The Mt. Michael specimen has the crown, breast,

than in excelsa from Mts. Hagen, Wilhelm, and Kubor, but these dif- 
ferences are minor. It differs most obviously from nominate picta in 
the olive-brown (instead of red-brown) crown and from lorentzi in 
the olive-brown (instead of blue-green) throat and in the red (instead 
of barred yellow) upper tail coverts.

DISCUSSION. ‘The specimen was netted at 10,200 ft in stunted 
moss forest. The two individuals that I saw in the field were perched 
15 or 20 ft above the ground in small trees. Paran said that this 
“tdnge” (as opposed to P. brehmii, the other “tange’’) was absent from 
the mountain behind Awande (about 7,500 ft high) but was present on 
a higher mountain behind Okapa (somewhat over 8,000 ft high). Com- 
bining this information with the collections of Gilliard and of Shaw- 
Mayer, one can say that this parrot is a regular inhabitant of forest on 
high mountains from elevations of about 8,000 ft up to at least 11,000 
ft, and probably higher. 


Relations of Psittacella madaraszi and P. modesta 


Psittacella madaraszi and P. modesta were formerly considered con- 
specific. Since the available evidence indicates that they are distinct 
and since some specimens have been misidentified in the literature 
of the last 15 years, the material in the American Museum of Natural 
History and the British Museum (Natural History) was reviewed. ‘Vable 
5 summarizes measurements. 

The morphological differences are as follow. P. modesta is in general 
larger (Table 5), but P. madaraszi increases in size from east to west, 
so that the westernmost population, P. madaraszi major, 1s as large as 
P. modesta. P. madaraszi has a stouter bill (culmen from cere 15 mm, 
as opposed to 13 mm in P. modesta). The female plumages are distinct: 
P. modesta females have orange-and-black barred breasts and brown 
heads, while P. madaraszi females have no or only obscure barring on 
the breast and have a green head with a blue forehead and a barred 
crown and hindneck. Adult males of the two species are very similar 
and have brown heads with yellow centers to the feathers and unbarred 
breasts. A yellow collar is present in adult males of P. modesta except 
for the nominate race, and is lacking in adult males of P. madaraszt. 
In each species the immature male resembles the adult female. ‘There 
are no morphologically intergrading specimens, although an intergrade 
would be easy to recognize in the female. 

Regarding recently collected material, all four of my Eastern High- 
lands specimens are P. madarszi hallstromi. Gilliard collected four 
specimens in the Eastern Highlands which he described as “P. modesta 
hallstromv” (= P. madaraszi hallstromi). Examination of these speci- 
mens shows that three of them, including the type of hallstromz, belong 
to P. madarasz. ‘The fourth, an immature male collected at 7,000 ft 
on Mt. Hagen and mentioned by Mayr and Gilliard (1954, p. 340), is 
unmistakably P. modesta and has a barred breast, green-washed brown 
head without yellow centers to the feathers, long wing (typical of 
P. modesta, longer than any known specimen of P. madaraszi), and 
lacks a yellow collar (present in adult males but lacking in females 
and immature males of P. modesta). At ‘Velefolmin, Gilliard collected

one male and two females, which he listed as P. modesta subcollaris 
(Gilliard and LeCroy, 1961, p. 41). Examination shows that the male 
is P. modesta subcollaris and that the females are P. madaraszi. In the 
Wahgi Valley Gyldenstolpe collected three males which I have not 
examined but which were evidently P. madaraszi hallstromi. At 8,000- 
9,500 ft in the Eastern Highlands Shaw-Mayer collected five specimens 
which Sims (1956, p. 404) assigned to hallstromi. Examination of these 
specimens in the British Museum (Natural History) shows that one is 
a juvenile P. madaraszi hallstromi (4, wing 91, collected at 8,000 ft in 
the Kubor Range, specimen number B.M. 1953.17.88) and that the

other four are P. modesta (é, wing 100, 8,500 ft, Mt. Giluwe, B.M.

unreported specimen of P. madaraszi at 7,500 ft at Baiyanka on the 
Purari-Ramu Divide (4, wing 94, B.M. 1942.1.6.7). 

The distributional details are as follows. P. modesta, consisting of 
the races collaris, subcollaris, and nominate modesta, occurs from the 
Vogelkop in the extreme west to long. 145°E in the Eastern Highlands 
but is absent farther east in the Herzog Mountains, southeastern New 
Guinea, and the Huon Peninsula. P. madaraszi, consisting of the races 
huonensis, hallstromi, major, and nominate madaraszi, occurs from 
eastern New Guinea (southeastern New Guinea, Herzog Mountains, 
Huon Peninsula) west along the Central Range to the Weyland Moun- 
tains but is absent on the Vogelkop in the far west. The two species 
are sympatric for a distance of at least 400 miles on the Central Range. 
Their altitudinal ranges appear to be mutually exclusive, with P. 
modesta living at higher altitudes than P. madaraszi. ‘Thus, in the 
Snow Mountains the Third Archbold Expedition took P. modesta at 
5,900-9,200 ft, P. madaraszi at 5,300 ft. At Telefolmin P. modesta was 
taken at 7,300 ft, P. madaraszi at 5,850 ft. In the Eastern Highlands 
P. modesta has been taken at 7,000-9,500 ft, P. madaraszi at 5,200- 
8,000 ft. 

‘The reconstructed evolutionary history is that P. modesta arose as 
a western isolate, P. madaraszi as an eastern isolate, of what was 
originally one small-sized Psittacella species. Each form has reinvaded 
most of the other’s geographical range, with altitudinal segregation 
as the ecological sorting mechanism, but P. modesta has not yet reached 
the eastern tip of New Guinea, and P. madaraszi has not yet reached 
the western tip. The birds of paradise Epimachus fastosus and E. 
meyert have the same distribution and presumably the same history. 


Psittacella modesta subsp.

As discussed above, this species was taken at 7,000 ft on Mt. Hagen

STOMACH CONTENTS. Insects; less often, insects and fruit. 

TAXONOMY. These specimens agree with orcophilus in that the 
bill is stouter than in infaustus. Of the three immature Karimui speci- 
mens, the male is in nearly adult plumage, with barring remaining 
only on the belly; the female is more immature, being entirely barred 
below and barred in a few patches above; while the specimen of in- 
determinate sex is entirely barred above and below. 

BREEDING. Of the eight adult males, the Bomai specimen, the 
Awande specimen, and three Karimui specimens had small testes, while 
the other three Karimui specimens had the testes slightly enlarged. 
Both adult females (from Karimui) contained large eggs nearly ready 
to lay. 

Paran shot the immature Karimui specimen of indeterminate sex 
while it was being fed by two wren-warblers Malurus alboscapulatus, 
which were also collected and proved to be two immature males. He 
said that at Awande, too, “asasaba’s’ (Malurus alboscapulatus) were 
the species that raised “petetébeye’s” (Cacomantis cuckoos). Malurus 
alboscapulatus was clearly breeding in the dry season both at Awande 
and at Karimui (p. 216). ‘The two laying females and the young im- 
mature suggest that Cacomantis variolosus also breeds in the dry 
season and has synchronized its breeding to that of its principal host. 


DISCUSSION. ‘This cuckoo is conspicuous because of its song, 
fairly common, and nearly ubiquitous in gardens, second-growth, trees 
in open country, and towns, ranging up to about 6,300 ft in this 
habitat. It has surely increased greatly in numbers and spread upward 
somewhat as a result of clearing of the forest in the Eastern Highlands. 
The preferred perches of C. variolosus are in the middlestory of trees 
overlooking open spaces. It is most frequently seen at heights of 
15-60 ft above the ground, rarely down to 10 ft or up into the crowns 
of tall trees. 

Ecological relationships among the three species of genus Cacomantis 
in New Guinea seem to me simple. C. variolosus inhabits open country 
from sea level up to about 4,000-6,300 ft, the upper limit depending 
upon the extent of ecological disturbance caused by man. C. castanei- 
ventris inhabits the forest interior over much of this same altitudinal 
range and is found regularly at the upper part of this range in the 
absence of man but is rare at sea level. C. pyrrhophanus inhabits both 
second-growth and the forest interior from about 5,000 ft upward and 
in effect takes over the niches of both its congeners at higher eleva- 
tions. In undisturbed areas altitudinal exclusion of the other two 
species by C. pyrrhophanus seems complete, though there may be 
marginal overlap in disturbed areas. 

VOICE. ‘There are two songs, both unmistakable (Fig. 18). ‘The 
first is a series of a half dozen similar three-note phrases, the series 


165 


SPECIES ACCOUNTS 


progressively rising in pitch, accelerating, and becoming louder, as if 
the singer were becoming progressively more excited. Each three-note 
phrase is in dotted rhythm and can be represented by the syllables 
“pe: - -te-to”, giving rise to the Fore name “petetdbeye’. The whole 
seriés consists of four to six repetitions of this basic phrase and lasts 
up to 5 sec. The other song, which is similar in form to the songs of 
several species of Chrysococcyx, has the same quality but consists of a 
series of nearly identical notes delivered at the rate of one per second, 
each note dropping in pitch at the end. The series may remain at 
constant volume and on constant pitch. It may also progressively drop 
slightly in pitch and grow louder without accelerating. A bird deliver- 
ing the second song may break into the “pe-- -te-to” song and then re- 
turn to the second song, giving the impression of an idling engine 
occasionally being set into motion. Both songs have the same whistled, 
shrill quality, carry well in open country, and are among the most 
characteristic sounds of Karimui station. Once I heard the “pe- - -te-to” 
song from a bird still in immature plumage. 


Cacomantis pyrrhophanus prionurus (Lichtenstein)

WEIGHT. 50.

TAIL. 140. 

STOMACH CONTENTS. Insects. 

TAXONOMY. ‘The Awande specimen belongs to the Australian 
race prionurus, recognized by its pale cinnamon underparts and dull 
gray back. It had a small ovary and must have been a winter visitor. 
‘Three specimens collected at Nondugl by Gyldenstolpe in August 
and September 1950 provided the first, and only other, record of this 
race from New Guinea. It has also been found on migration to the 
Aru Islands. ‘The resident New Guinea race excitus is quite distinct 
in its dark rufous-brown underparts and dark shining slaty dorsal 
coloration. 


BREEDING. Bulmer recorded one egg in a nest of the wren- 
warbler Malurus alboscapulatus, which is the principal host of Caco- 
mantis variolosus at lower elevations; and I observed a juvenile being 
fed by the warbler Sericornis nouhuysi. 

DISCUSSION. Gilliard, Gyldenstolpe, Shaw-Mayer, and Bulmer 
each collected one or two specimens of C. p. excitus, and Gilliard re- 
ported it “very common,” but this is probably true only very locally, 
as I did not find it either on Mt. Michael or on Mt. Karimui and 
other observers have generally found it rare. In the Eastern Highlands 
its altitudinal range is about 5,000 to 9,500 ft, largely above that of the

BREEDING. ‘The gonads were small except in the Soliabeda male 
and a Karimui male and female, which had the gonads slightly en- 
larged. 


DISCUSSION. All 11 specimens were obtained inside the forest, 
and seven of them were netted, suggesting that this cuckoo spends 
much time in the understory. One immature male and subadult female 
were found together in the same net. I never saw the species in life, 
but song records and reports of natives indicate that it is uncommon, 
local, and shy, and lives in forest up to about 6,000 ft. 


VOICE. Natives attribute a mournful, slow, three-note song at 
medium-low pitch to this species. ‘he pattern is distinctive: the first 
and third notes are leisurely and upslurred, the second note shorter, 
and the first note is higher in pitch and separated by a longer time in- 
terval from the second and third (Fig. 18, p. 167). The identification is 
consistent with the three-note songs described for this species by Stein 
(1936, p. 49) and by Ripley (1964, p. 36). On the north coast of New 
Guinea I heard the same song differing only in that the final note was 
trilled, so that the identification may still be compatible with Rand’s 
description (Mayr and Rand, 1937, p. 63) of the song of C. castanei- 
ventris as a “full rich trill.”

Genus Chrysococcyx! 


The three resident New Guinea species form an altitudinal sequence 
in forest, with C. ruficollis at the highest elevations, C. meyerii at 
middle elevations, and C. malayanus (not yet reported from the Eastern 
Highlands) at the lowest elevations. An additional species, C. lucidus, 
occurs in open country in the Eastern Highlands as a winter visitor 
from Australia. 


Chrysococcyx lucidus plagosus (Latham) 
Golden Bronze Cuckoo 


SPECIMEN EXAMINED. Lufa: 1 9 (29 June 1964). 


DISCUSSION. My sole specimen of this Australian winter visitor 
was shot from a perch 20 ft above the ground in a lawn casuarina at 
Lufa Patrol Post (6,300 ft). A modest number of specimens have been 
obtained by others (four at Nondugl by Gyldenstolpe, one each at 
Nondugl and in the Kubor Mountains by Gilliard, four in Kyaka 
territory by Bulmer), suggesting that the species’ appearances in the 
Eastern Highlands are regular. 


Chrysococcyx ruficollis (Salvadori) 
Mountain Bronze Cuckoo 


I did not encounter this cuckoo, which appears to be rare and local 
in mountain forest between 6,000 and 8,500 ft. Ihe known records in 
the Eastern Highlands are two specimens collected in the Kubor Range 
(one each by Gilliard at 7,000 ft and by Hitchcock at 6,400 ft), one on 
Mt. Wilhelm at 8,500 ft by Gilliard, and one at 6,000 ft on the north 
slope of Mt. Hagen by Bulmer.

WEIGHT. 1 3: 19.3. 1 9: 20.7. 

WING. 1 4:90. 1 9: 92. 

DISCUSSION. Meyer's Bronze Cuckoo is solitary and uncommon 
but widespread up to 5,000 ft, rarely up to 6,000 ft, and has been 
encountered by most collectors. It is found in the forest or at the forest 
edge but seems to prefer the latter. In the field this cuckoo suggests a 
sluggish flycatcher in its behavior. It moves slowly in the middlestory, 
usually 15 to 40 ft above the ground, catching insects.

VOICE. A series of six or seven identical notes at intervals of 
about | sec or less, each note dropping slightly in pitch at the end. 
The ‘pitch is high, the quality plaintive and clear, the volume soft. In 
pattern this resembles the second song of Cacomantis variolosus but is 
much weaker in volume and slightly more leisurely in tempo, pre- 
cluding the possibility of confusion. The song of Chrysococcyx lucidus 
lucidus, which I heard in New Zealand, is similar in pattern. Published 
descriptions of the songs of C. ruficollis (Stein, 1936), C. basalis (Cayley, 
1959), and C. lucidus plagosus of Australia (Cayley, 1959) are also 
similar, but that of C. malayanus (Cayley, 1959) is apparently quite 
different.

STOMACH CONTENTS. Fruit. 

‘TAXONOMY. ‘The coloration of these birds is not gray but in- 
stead is rufous, placing them with the race nominate parva (grisescens 
is restricted to northern New Guinea). The iris was red. ‘The immature 
male from Mengino has the throat already orange-brown, as in the 
adult male, rather than gray, as in the female and immature male; 
the mustache stripe is charcoal but not yet the steely blue of the adult 
male; the gray stripe between the eye and mustache is already 
ochraceous posteriorly; the crown is still dark brown, with just a few 
scattered steely blue feathers. 

BREEDING. ‘The Okasa male and female, a pair shot from the 
same tree, both had enlarged gonads. 

DISCUSSION. ‘The above specimens constitute the sole Eastern 
Highlands records of this very uncommon cuckoo. ‘The Mengino 
specimen was shot 50 ft above the ground in a fruit tree at 4,600 ft in 
open second-growth forest near a river, at the upper limit of the 
species’ altitudinal range. In addition to these specimens, a pair was 
seen in the middlestory of a tree at Karimui. 

VOICE. ‘The song, delivered from a treetop perch, is similar to the 
common song of Eudynamis scolopacea (Fig. 18, p. 167) but weaker: a 
series of pairs of notes, each pair louder and on a higher pitch than 
the previous pair. ‘The elements are sometimes three repeated notes 
or else single downslurs rather than a pair of notes. Another variant 
is a series of identical upslurs at 114-sec intervals, similar to the voice 
of Cacomantis variolosus in quality.

Eudynamis scolopacea rufiwenter (Lesson) 
Indian Koel 


SPECIMENS EXAMINED. Karimui: 1 ¢ (11 Sept. 1965). 

WING. 185. 

STOMACH CONTENTS. Fruit, 9-41 mm in diameter. 

TAXONOMY. The small size places the specimen with rufiventer, 
the breeding race of most of New Guinea, rather than with swbcyano- 
cephala, which is in southern New Guinea as a wintering visitor from 
Australia and as a resident (Rand, 1941). Females of these two races 
are quite distinct in plumage. Cuckoos agreeing closely with the female 
of rufiventer were seen but not collected at Karimui. 

BREEDING. ‘The testes were somewhat enlarged. 

DISCUSSION. ‘The Indian Koel was heard or seen nine times at 
Karimui in August 1964. In 1965 the only records were of the specimen 
(11 Sept.) and of a song heard on 15 Sept. I was particularly interested 
in tracing the unmistakable song and am certain that I did not hear 
it in the dry months of June, July, or August 1965. Probably local 
migration within New Guinea is involved. All Koels seen were solitary, 
and were either feeding in the middlestory of fruit trees, or else sing- 
ing from commanding perches at the tops of very tall trees overlooking 
open spaces. Eastern Highlands records of this tropical species are 
lacking except at Karimui. 

VOICE. ‘There are four types of vocalizations, all loud. ‘The com- 
mon song is a series of about a dozen pairs of notes, the first note of 
each pair on the same pitch as the second but shorter (Fig. 18, p. 167). 
Successive pairs rise in pitch and increase slightly in volume. The whole 
song lasts about 5 sec. Another song consists of three upslurs, the 
second following 2 sec after the first and on the same pitch, the third 
1 sec after the second and on a slightly higher pitch (Fig. 18). Each 
upslur has a sense of forward momentum and sounds as if it came from 
a bird much larger than the Koel. A single such slur is sometimes given 
as a call. ‘he common alarm note is a rapidly repeated, musical, 
emphatic, staccato note “whik-whik-whik .. .”” reminescent of Para- 
disaea minor. An alternative alarm note is a disagreeable upslur.

DISCUSSION. ‘These two specimens provide the sole records for 
this low-altitude treetop cuckoo in the Eastern Highlands. Elsewhere 
in New Guinea, too, the species is local, being common in a few areas 
and absent in others. The Karimui bird was perched alone in a tree 
at the edge of a clearing. The Mt. Karimui bird, one of two in ad- 
Jacent trees in primary forest, was collected at 5,700 ft, which is 
unusually high for the species. Daribi natives said that it occurs 
regularly in the Karimui area. 

VOICE. According to natives, three or four loud rapid notes on 
the same pitch.

TAXONOMY. All specimens have the plumage unbarred. ‘The 
iris was red, and the bill whitish. 

BREEDING. Both males had two testes, which were small. 


DISCUSSION. ‘There are no Eastern Highlands records for the 
Greater Coucal other than from the Karimui area, where it was 
uncommon. The presence at Karimui (3,650 ft) and on the lower slopes 
of Mt. Karimui (up to 4,200 ft) is somewhat above the normal altitudi- 
nal range of the species. It ranges from the ground to about 50 ft 
above the ground, and has a characteristic habit of clumsily hopping 
up the trunk of a small tree, switching its long tail from side to side 
as it goes. The Soliabeda specimen was surprised while trying to eat 
two small birds out of our mistnets. 

Although C. menbeki and C. phasianinus both may be found in 
second-growth, their average habitat preferences are different: C. 
phasianinus is mainly found in grassland, while C. menbeki (but never 
C. phasianinus) occurs in the forest. In addition to these differences in 
habitat preference, it is surprising how infrequently the two species 
even occur in the same locality. 

VOICE. The common call is a series of about four hollow, boom- 
ing, sometimes disyllabic notes “hoo” or “coo-a”, similar in quality to 
the calls of Macropygia nigrirostris or species of Ptilinopus. This call 
may be heard for some time after sunset. Less frequently heard is a 
peculiar and totally unmusical call consisting of a staccato upslurred

grunt like the croak of a bullfrog, followed by a dry, rapid, rattled 
series of notes rising in pitch. 


Centropus phasianinus propinguus Mayr 
Pheasant Coucal 


DISCUSSION. ‘The only definite Eastern Highlands records of this 
grassland coucal are from the grassland of the Baiyer Valley, where 
Gilliard and Bulmer collected it and Bell found it common up to 
about 5,000 ft. In addition, native informants told Bulmer that it 
occurs in the Kaironk Valley of the Schrader Range up to 5,500 ft and 
near Banz. Elsewhere in New Guinea C. phasianinus is confined to 
altitudes generally below 2,500 ft, and it has not colonized the Baliem 
Valley grasslands of western New Guinea. However, the large expanses 
of grassland in the Eastern Highlands appear to be ideal habitat for 
it, and it will be interesting to see whether it succeeds in colonizing 
other parts of the Eastern Highlands besides the Baiyer Valley. 

VOICE. A series of dull, hollow, booming notes which accelerate 
in tempo, similar in quality to the call of C. menbeki.

DISCUSSION. ‘The specimens were collected from second-growth 
trees in the Okapa area where I also saw an individual at sunset flying 
at the edge of the forest and uttering monosyllabic screams. The Barn 
Owl is generally distributed in low numbers through the Eastern High- 
lands (other records by Gilliard, Gyldenstolpe, and Bulmer).

SPECIES ACCOUNTS 


DISCUSSION. The Fore knew of only one pair of this little-known 
forest barn owl living within a wide radius of Okapa. Shaw-Mayer col- 
lected one individual each at 8,500 ft in the Hagen Range and the 
Lamende Range, Gilliard collected a young bird at 7,000 ft in the 
Kubor Range, and there are records of two birds brought into Nondugl 
aviaries. On Mt. Albert-Edward I found an individual sleeping during 
the day in a hole under the roots of a forest tree. 

Van Deusen (pers. comm.) analysed bones in the regurgitated pellets 
of two individuals of Tyto tenebricosa and kindly provided the follow- 
ing details, which offer valuable insight into its diet. The first set of 
pellets was found under a boulder in alpine grassland on Mt. Wilhelm 
at 12,000 ft. The three major prey species were the rats Rattus niobe 
and Pogonomelomys sp., and, to a lesser extent, the bandicoot Pero- 
ryctes longicauda. All three live in alpine grassland. ‘There were also 
a few bones of the small marsupial Eudromicia caudata from the ad- 
jacent subalpine forest, the rats Neohydromys sp. and Pogonomys sp., 
the large wallaby Thylogale bruijni (probably taken as carrion from 
wild dog kills), and an unidentified bird. The second set of pellets came 
from a boulder roost at the edge between forest and grassland at 7,800 
ft in the Cromwell Mountains. ‘The dominant prey species proved to 
be the common arboreal forest marsupial Psewdocheirus forbes. Other 
prey included the giant rats Hyomys sp. and Mallomys sp., the small 
forest rat Anisomys sp., the rat Rattus exulans, three forest marsupials 
(the bandicoot Peroryctes raffrayanus, the flying phalanger Petaurus 
breviceps, the wallaby Dorcopsulus vanheurnz), the large wallaby Thy- 
logale bruijni (probably taken as carrion), the forest bats Nyctimene 
sp. and Syconycteris sp., and unidentified birds. 

VOICE. According to natives, a long, high-pitched, slightly down- 
slurred note, suggestive of the neighing of a horse. 


Tyto capensis papuensis Hartert 
Grass Owl 


Of the three barn owls occurring in the Eastern Highlands, this 
seems to be the least uncommon. Gilliard, Gyldenstolpe, and Shaw- 
Mayer all observed it over grassland and obtained two specimens each. 
It has also been discovered in western New Guinea in the grassland 
of the Baliem Valley by Ripley (1964).

WING. 186. 

STOMACH CONTENTS. Insects 25 mm long, and a few mammal hairs. 

BREEDING. The testes were small. 

DISCUSSION. The specimen was caught in a mistnet inside the 
forest at Karimui. I heard the call of this owl, which is the commonest 
nocturnal bird call in New Guinea forests, from the forest and forest 
edge up to 6,450 ft on Mt. Karimui. Other Eastern Highlands records 
are from Lake Kutubu (Schodde and Hitchcock), the Baiyer Valley 
(Bulmer), Kup (Gilliard), and 8,200 ft in the Hagen Range (Shaw- 
Mayer). 

VOICE. ‘Two identical downslurred notes at an interval of slightly 
less than | sec, resembling the call of Ninox novaeseelandiae which I 
heard in New Zealand. On different occasions I recorded the call as 
“kyew kyew” or “hyew-ew hyew-ew” or “kru kru.” 


PODARGIDAE: FROGMOUTHS 
Podargus papuensis Quoy and Gaimard 
Great Papuan Frogmouth 

NATIVE NAMES. Fore: yasa. Daribi: uni. 

DISCUSSION. Podargus papuensis is rarely seen but is widespread 
through the Eastern Highlands in low numbers in forest and in 1so- 
lated trees up to about 7,000 ft. My sole observation was in daylight 
at Karimui, when my Fore assistants pointed out to me a bird which 
had been disturbed by their approach. It was perched motionless and 
upright, with its head turned towards us, 30 ft above the ground in a 
tall tree at the edge of a clearing. ‘This frogmouth sometimes sits with 


its mouth wide open for long periods, with a sticky substance on its 
palate that might serve to attract or trap insects.

of these being in a group of three. I never observed this frogmouth 
in the field, but, to judge from the number of specimens, it may be 
the least uncommon nocturnal bird in forest up to about 5,000 ft.

WING. 154. 

TAME. 22: 

DISCUSSION. ‘The unique type of this very distinct race was 
caught by hand by a Karimui native, who found it sleeping in a tree 
during the day. It differs from other races most notably in its larger 
size (wing and tail 25% longer than in nominate bennetti, the other 
southern New Guinea race) and in its much darker, blacker upper- 
parts (see Diamond, 1967a, p. 6 for diagnosis). It represents an altitudi- 
nal record for this lowland species, and is of interest in illustrating 
evolutionary divergence in lowland birds isolated in the Karimui 
Basin as well as the tendency of these populations towards darker 


plumage (p. 56).

WING. 122. 

TAL. 169. 

TAXONOMY. Comparative measurements of all 23 specimens 
known of this species have been summarized elsewhere (Diamond, 
1969). The Karimui specimen completely lacks a light collar on the 
hindneck, of which there are suggestions in some gigas and manni 
specimens. The light buffy V-shaped mark on the forehead is about as 
distinct as in the one available specimen of nominate wallacii from 
the Vogelkop and more distinct than in the one available wallaci 
specimen from the Aru Islands. ‘The lower belly is palest and has the 
fewest markings in the Vogelkop specimen. ‘The loose arrangement of 
white dots on the undersurface of the tail into bands is least distinct 
in the Karimui specimen. 

DISCUSSION. ‘This is a rare species with a very local distribution, 
recorded near sea level in the Aru Islands, southwestern New Guinea, 
and the Vogelkop and at medium elevations in the Weyland Moun-

STOMACH CONTENTS. Insects. 

TAXONOMY. The type of Aegotheles archboldi differs in its 
richer dorsal coloration, coarser white spots on the back, and coarser 
and darker breast markings. Since both A. albertisi: and A. archboldi 
exist in two color phases and show much individual variation and 
since the complex plumage patterns defy simple description, identifica- 
tion in the absence of comparative material is impossible. 

BREEDING. ‘The testes were large in one Okasa male, small in the 
other. 


DISCUSSION. ‘This aegothelid was also collected by Gilliard, Gyl- 
denstolpe, and Shaw-Meyer, and is common but secretive in forest 
from about 4,500 to 8,500 ft. ‘Iwo of the adults were netted, two others 
were seen flying out of holes in trees when disturbed during the day, 
and the juvenile was caught by hand in a garden. 

The relations among the small midmontane forest aegothelids of the 
albertisit-archboldi complex remain to be clarified. A. archboldi was 
originally described as a race of A. albertisii. Proceeding from west to 
east in the mountains of New Guinea, the distribution of the popula- 
tions is as follows: A. albertisi albertisti, Vogelkop; A. albertisti 
wondiwoi, Wandammen Peninsula; A. albertisii salvadoriit, Weyland 
Mountains to Wissel Lakes; A. archboldi, Wissel Lakes to Mt. Wil- 
helmina; A. albertisi salvadoru, Mt. Goliath; A. archboldi, Tele- 
folmin; and A. albertisit salvadori, Eastern Highlands, Huon Penin- 
sula, and southeast New Guinea. The only locality where both A. 
albertissi and A. archboldi have been taken is the Wissel Lakes. As 
Ripley (1964) points out, the altitudinal range of A. albertisti (ca. 
3,800-8,600 ft, combining various records in the literature) is on the 
average lower than that of A. archboldi (ca. 7,000-12,000 ft, except for 
a native-procured ‘Telefolmin specimen listed (Gilliard and LeCroy, 
1961, p. 43) as from 4,800 ft but probably from an unknown eleva- 
tion. Thus, the geographical distributions are disjunct and largely 
but not completely complementary (“checkerboard allopatry,” p. 39), 
and the altitudinal ranges are possibly complementary in the areas of 
local overlap.

WING, 24: 157, 163; 2 ©: 160, 165. 

STOMACH CONTENTS. Insects. 

TAXONOMY. Three of the specimens are in the dark phase, 
while the Zone 8 male is intermediate between the dark phase and 
light phase. Gilliard and LeCroy (1961, p. 43) point out that dark 
phase plumage probably succeeds light phase plumage in the same 
individual. 


BREEDING. Both males had the testes slightly enlarged. 


DISCUSSION. All four specimens were caught in mistnets between 
5,000 and 7,900 ft. Other collectors in the Eastern Highlands have also 
found the species at most collecting stations in forest between about 
4,000 and 8,500 ft, a range which d. insignis shares with A. albertisit. 
Niche differences probably are related to size, since A. insignis is twice 
as heavy as A. albertisit. 


CAPRIMULGIDAE: GOATSUCKERS 


Caprimulgus macrurus yorki Mathews 
White-tailed Nightjar 


NATIVE NAMES. Fore: k’ru-k’runta.

BREEDING. Three “nests” were found: sets of two coffee-colored 
eges with sparse, small, ight grey-brown blotches, measuring 30-34 
22-23 mm, laid directly on the ground. 

DISCUSSION. ‘This goatsucker was heard calling from grassland 
and gardens at Miarosa (5,800 ft), Okapa (6,600 ft), and Mengino 
(6,150 ft), but not at my other stations. In particular, despite the vast 
expanses of grassland at Okasa, and despite the number of lowland 
species that have colonized Karimui, I found it at neither locality and 
presume it to be absent because its distinctive, frequently-given call 
could not have been missed. ‘The experience of other observers in the 
Eastern Highlands indicates an equally spotty distribution. ‘The clear- 
ing of the forest has permitted this lowland species to spread up to the 
newly created midmontane grassland not only in the Eastern High- 
lands but also at Telefolmin (Gilliard and LeCroy, 1961, p. 43) and in 
the Baliem Valley of western New Guinea (Rand, 1942b, p. 457; 
Ripley, 1964, p. 40). It emerges just after sunset to hawk for insects in 
cleared areas.

on 15 May 1952 (Mayr and Gilliard, 1954). All New Guinea records 
are from the eastern half of the island except for one bird taken at 
the Idenburg River by the Third Archbold Expedition. At Lake 
Kutubu Schodde and Hitchcock observed Eurostopodus nightjars with- 
out large white marks in the tail or wing and tentatively identified 
them as E. papuensis, but this description might also fit E. mystacalis. 


Eurostopodus archboldi (Mayr and Rand)

STOMACH CONTENTS. Large insects, including a cicada. 


DISCUSSION. Four specimens of this rare high-altitude nightjar 
have been taken in the Eastern Highlands: one at 10,000 ft in moss 
forest on Mt. Hagen (Mayr and Gilliard, 1954, p. 342), one at 8,000 ft 
on Mt. Hagen, and two at 7,300-7,500 ft on Mt. Giluwe (Sims, 1956, 
407). In 1964 the Seventh Archbold Expedition obtained a single 
specimen on the Huon Peninsula, whence the species had not pre- 
viously been recorded. Only eight other specimens have been reported: 
the type series of three from 7,900 ft on Mt. Tafa, southeastern New 
Guinea (Mayr and Rand, 1935, p. 4); a specimen I collected at 8,200 ft 
on Mt. Albert-Edward, southeastern New Guinea; three from about 
10,600 ft in the Lake Habbema area of western New Guinea (Rand, 
1942b, p. 457); and one from 7,500 ft in the Ilaga Valley of western 
New Guinea (Ripley, 1964, p. 40). The geographical range is thus 
extensive, but the distribution is extremely spotty. My Mt. Albert- 
Edward specimen was one of a pair hawking silently in a forest clearing 
at dusk, flying from just above the treetops to about 30 ft above the 
ground and periodically perching on a dead tree.

‘TAXONOMY. ‘This small series illustrates the clinal increase in 
size with altitude which emerges more clearly from larger series (e.g., 
Archbold, Rand, and Brass, 1942, p. 285). 

BREEDING. ‘The gonads were small in these specimens. Three 
nests were found under overhanging boulders beside streams. ‘The nests 
were crude cups of moss 10 cm in diameter and 8 cm deep, and con- 
tained two young. An adult gathered moss for one of these nests by 
repeatedly hovering to pick it off the bark of a tree. 

DISCUSSION. ‘The habitat preferences of this swiftlet depend 
upon altitude. Above 5,000 ft C. esculenta may be seen over almost any 
kind of habitat (midmontane grassland, gardens, second-growth, pri- 
mary forest, alpine grassland) up to 12,000 ft. At these higher eleva- 
tions it sometimes forms mixed flocks with C. hirundinacea, but on 
the average C. esculenta forages nearer the ground and closer to 
vegetation, C. hirundinacea usually higher and more in the open, 
though under misty conditions GC. hirundinacea may also forage within 
a few feet of the ground. C. esculenta generally flies below the level of 
the treetops, occasionally even inside the forest in more open areas, 
and circles and skims close to the foliage. In the hill forest below 4,500 
ft in the parts of the Eastern Highlands I studied, C. esculenta is strik- 
ingly and absolutely confined to river gorges. ‘hus, in the vicinity of 
Karimui (3,650 ft) and Bomai (3,250 ft) airstrips C. hirwndinacea was 
present daily in flocks of dozens, sometimes over a hundred birds, at

any height down to nearly ground level, but not once did I see C. 
esculenta in these flat cleared areas. A few hundred feet away C. escu- 
lenta reappeared as the only swift in the river gorges at the edge of 
these two airstrips. Similarly, C. esculenta was the only swift at our 
4,500 ft camp on the Sena River, in the river gorges between Karimut 
and Soliabeda, and in the Wi River gorge at 1,350 ft below Soliabeda, 
where the one Soliabeda specimen was collected, but the species was 
absent from the rolling terrain 500 ft above the Wi River, where 
Soliabeda village itself was located. At Lake Kutubu (2,450 ft) Schodde 
and Hitchcock (1968, p. 35) also noted ecological segregation between 
C. esculenta and the other swiftlet present (C. vanikorensis or C. 
hirundinacea), with the former confined to a river and nearby forest 
glades, the latter over cleared areas distant from primary forest.

TAXONOMY. Collocalia hirundinacea and C. vantkorensis are im- 
possible to distinguish in the field and very difficult in the hand. Char- 
acters that I found useful are that C. vanikorensis has a slightly larger 
(wider and longer) bill; most but not all C. hirundinacea have feathered 
tarsi, and most but not all C. vanikorensis have unfeathered tarsi; C. 
vanikorensis tends to be more brown on the uppersurface and under- 
surface, while C. hirundinacea tends to have more of a blue sheen 
above (especially on the head) and to be more gray and paler below; 
and C. hirundinacea shows more white at the base of the dorsal feathers 
when the back is ruffled. All specimens collected at Karimui and Bomai 
proved to be C. hirundinacea. 

DISCUSSION. ‘The sex ratio pee progressively throughout 
July 1965. Only males were taken on 2, 3, 4, and 7 July. On 10 July 
one male and three females were ce on 11 July one male and one 
unsexed bird. Only females were taken on 12, 14, 15, and 16 July. 

Flocks of brown swiftlets which must have been either this species 
or C. vanikorensis (as opposed to the blue C. esculenta) were observed 
daily over airstrips, grassland, and cleared land from 2,000 ft up to 
alpine grassland at 11,000 ft. In general, C. hirundinacea is found at 
higher elevations, C. vanikorensis at lower elevations. Since my Karimui 
and Bomai specimens were all C. hirundinacea, 1 presume that those 
from the higher stations, where no specimens were taken, were also 
C. hirundinacea. As discussed under the preceding species, habitat

segregation between C. hirundinacea and C. esculenta was strict at 
lower elevations, but mixed flocks occurred at higher elevations. 
VOICE. A high-pitched twittering. 


Collocalia whiteheadi nuditarsus Salomonsen 
Whitehead’s Swiftlet 


The only Eastern Highlands records are four specimens collected by 
Gilliard at 5,000-6,000 ft in the Kubor Mountains, plus breeding rec- 
ords at 6,000 ft in the Kaironk Valley of the Schrader Range (Bulmer, 
pers. comm.). Somadikarta (1967) was the first to recognize that the 
Idenburg River swiftlets, formerly placed in the same subspecies as 
the populations now known as nuditarsus, actually belong to a distinct 
species, C. papuensis. Whether nuditarsus is actually conspecific with 
C. whiteheadi of the Philippines is uncertain.

STOMACH CONTENTS. Insects. 

BREEDING. All the Bomai specimens (collected in July) were in 
nonbreeding condition, while the Karimui female (collected in August) 
had enlarged ovaries. 


DISCUSSION. I found this striking bird only in the Karimui 
region, up to 4,500 ft (Soliabeda, Bomai, Karimui, Sena River), where 
its distribution seemed local—i.e., it was uncommon and seen ir- 
regularly except at Bomai, where several were seen every day in a 
particular garden. Group of two to four birds, occasionally solitary 
individuals, occupied conspicuous perches in open areas in the crowns 
of tall trees with little foliage, from which they sallied out, circled 
briefly with strong, falcon-like flight, and returned to the same perch. 
The Soliabeda, Bomai, and Karimui birds were in highly disturbed 
habitats (gardens and other areas which had been extensively cleared 
but had a few tall trees remaining). ‘The Sena River record was in 
undisturbed forest, where a pair used a tall tree on the bank overlook- 
ing the open space over the river as a perch. Gyldenstolpe (1955, 
p. 72) once saw one individual of H. mystacea over Nondugl (5,200 ft), 
and Bulmer mentions it as present below 5,000 ft in the Schrader 
Range. 


182 


SPECIES ACCOUNTS 


H. mystacea is worth citing as an example of a low-elevation species 
that has failed to colonize Eastern Highlands garden areas above 5,000 
ft, although the nature of the habitat seems to correspond well to its 
normal lowland habitat and although the colonization would have 
necessitated only a small step above its normal altitudinal range, which 
extends to ca. 4,000 or 4,500 ft. 

VOICE. The call is a high downslur, nearly a squeal. 


ALCEDINIDAE: KINGFISHERS 
Ceyx azureus lessonii (Cassin) and C. a. ochrogaster (Reichenow)! 
Azure Kingfisher 

SPECIMENS EXAMINED. Sena River: 1 ¢@, 1 9 (26 and 27 July 1964). 

WING. 1 ¢: 73. 

STOMACH CONTENTS. Insects. 

TAXONOMY. ‘The darker ochraecous wash of the underparts 
places the specimens with the southern New Guinea race lessonii, to 
which the Lake Kutubu population also belongs. Sims (1956) assigned 
a female taken at Minj (5,000 ft) in the Wahgi Valley by Shaw-Mayer 
to the northern New Guinea race ochrogaster. 

DISCUSSION. ‘This kingfisher lives near small streams, including 
brooks as little as 2 ft across, or in the understory of the forest. All 
individuals that I saw were solitary and perched within 5 ft of the 
ground. Periodically a perched bird quickly raises and lowers its whole 
body while holding its legs in place, an action comparable to a man on 
horseback “posting” in the saddle when the horse is in the trotting gait, 
and similar to the “posting” of Salpinctes obsoletus (Troglodytidae) of 
North America and Xenicus gilviventris (Acanthisittidae) of New 
Zealand. ‘The purpose of the action is probably to assist vision by 
obtaining a different perspective or estimating distance by parallax.

elsewhere below 4,000 ft. In the Karimui region it was uncommon 
and solitary in the understory of the forest interior and forest edge, up 
to about 15 ft above the ground. Often it occurs away from water, but 
I saw one pair perched on a branch above a small brook, periodically 
plunging into the water directly beneath them and immediately re- 
turning to the same perch. Like Ceyx azureus, C. lepidus periodically 
“posts” up and down on its legs.

WING. 3 4: 116,118,119. 3 @: 111, 119, 120. 

TAXONOMY. The light highlights on the black crown of the 
female place this series with nominate macrorhina, as expected on 
geographical grounds, rather than with the north coast form jobiensis. 
‘The 29 July Soliabeda female, but not the other specimens, is buffy 
below, a character of immatures and some adults. 


BREEDING. ‘The gonads were slightly enlarged in the 26 July 
Soliabeda female, not enlarged in the other specimens. 


DISCUSSION. Five of the seven specimens were netted. In the 
Karimui area this is evidently a not uncommon species in the lower- 
and middlestory of the forest interior. Elsewhere in New Guinea M. 
macrorhina is regularly encountered only at elevations below 3,000 or 
2,000 ft, and the only other Eastern Highlands record is a single female 
taken at Lake Kutubu. This kingfisher is nocturnal, and is unobtru- 
sive, solitary, and silent during the day, so that my sole sighting was 
of a bird 20 ft above the ground in dense foliage. 

VOICE. ‘The call (Fig. 19, p. 186) is heard only at night. It consists 
usually of two whistled notes, the second conspicuously shorter than 
the first, a half-tone higher, sometimes trilled, and following the first 
by slightly less than 1 sec. Occasionally two additional shorter notes 
are added at a higher pitch. The kingfishers Melidora macrorhina, 
Clytoceyx rex, Halcyon torotoro, H. megarhyncha, H. macleayi, and 
Tanysiptera galatea betray their relationship in the similar whistled 
qualities of their calls.

WHOLE CULMEN. 46. 

TAXONOMY. In dorsal coloration the specimen is darker than 
Fly River, Bernhard Camp, and Jimmi River specimens, comparable 
to Mt. ‘Tafa specimens, and paler than ‘Velefolmin specimens. Since 
variation in darkness follows a checkerboard geographical pattern, the 
race septentrionalis is not recognized. 

DISCUSSION. ‘The only other Eastern Highlands specimens of this 
uncommon and sparsely distributed species are three from the Jimmi 
River presented to Gilliard, and one shot at 6,000 ft on Mt. Wilhelm 
by Shaw-Mayer. I heard its song at eight localities between 2,000 and 
6,500 ft, from the forest or forest edge. The specimen was surprised on 
the ground while eating a snake. According to Paran, Clytoceyx is 
solitary, and most in evidence at Awande in the rainy season, when 
it perches on trees or fences overlooking gardens and flies down to the 
ground to locate its food of large insects, grubs, and small mice. 

VOICE. An unmistakable, clear, liquid, ventriloquial three- or 
four-note, whistled call that is delivered from the crown of a tall tree 
and carries well. ‘The whole call takes not quite | sec. ‘The commonest 
pattern is of three notes in descending pitch, the first two separated in 
pitch by an interval of a second or minor third, the second two by a 
fourth or major third (Fig. 19). Less often there is a fourth note, giving 
rise onomatopoetically to the name “u-se-ré-po”. At each note of the 
call the tail is jerked. Another call consists of three or four louder, 
rapid, muscal notes on the same pitch. I have heard the call only in 
the morning, and most often shortly after dawn.

STOMACH CONTENTS. Insects, often large ones such as grasshoppers. 

BREEDING. All specimens had small gonads, hence breeding is 
not in the dry season. 


DISCUSSION. ‘The Karimui population of this noisy, conspicuous, 
and belligerent lowland kingfisher was considerably above its normal 
altitudinal ceiling, and elsewhere in the Eastern Highlands it has 
been recorded only at Lake Kutubu (2,450 ft). It was usually seen 
perched singly in the middlestory, occasionally in the understory or 
crown, of second-growth, gardens, forest edge, and occasionally forest. 
The tail is often cocked up when perched or when fighting. I have 
observed fights with others of its species and with Coracina papuensis.

VOICE. Loud, and exercised from conspicuous perches. Most 
vocalizations consist of a series of a half dozen or more separate notes 
at intervals of 1 sec. The quality is either: (a) clear barking notes as 
of a small but noisy dog, all barks being on the same pitch; (b) more 
squealing, downslurred barking notes, all again being on the same 
pitch; or (c) barking notes, each of which is trilled; in this case suc- 
cessive notes are on lower pitches (Fig. 19, p. 186). As with Dacelo 
leachii and D, novaeguineae, two nearby individuals of D. gaudichaud 
often bark simultaneously; this may represent male-female duetting.

STOMACH CONTENTS. Insects. 

TAXONOMY. ‘The underparts of the Karimui specimen are as 
pale as in meeki and brevirostris, and paler than in pseustes. ‘The 
length of the culmen from the anterior edge of the nostril to the tip 
was measured in four females each of four races: tentelare, 32, 33, 33, 
DAS PsCuUstes; 30). 924925, 04; DREUITOSLTIS, 28,29) Dlx: O15) MEER, ly 38, 
34, 34. The short bill of brevirostris eliminates it, and the Karimui 
specimen must be assigned to meeki, a slight westward range extension. 
The ranges of southern New Guinea races given by Rand (1938, pp. 
11-12) may thus be reformulated as follows: meeki, southeastern New 
Guinea, west to Karimui (Purari drainage, long. 145°E); pseustes, 
southern New Guinea from the mouth of the Fly River (long. 143°E) 
west to the Mimika River (long. 136°E) except for the range of brevi- 
rostris; nominate torotoro, northern and western New Guinea, on the 
south coast east to Etna Bay (long. 135°E); brevirostris, near the coast 
at long. 142°E in the bulge of southern New Guinea. 


BREEDING. ‘The ovary was small. 


DISCUSSION. ‘This was quite an uncommon species in the Kari- 
mui Basin, and has not been recorded elsewhere in the Eastern High- 
lands. On the three occasions I saw it, solitary individuals were perched 
2-15 ft above the ground in open second-growth, and jerked or cocked 
the tail at frequent intervals. The altitudinal range of H. torotoro 
excludes that of its higher-altitude sibling H. megarhyncha. In the 
Karimui Basin the transition takes place at some altitude between 
3,650 ft, the highest H. torotoro record, and 4,400 ft, the lowest H. 
megarhyncha record (the transition usually takes place somewhat be- 
low 3,000 ft in the rest of New Guinea). Although H. torotoro and 
H. megarhyncha are very similar in appearance as well as in voice, 
they are evidently distinct species: their sizes do not overlap if indi-

viduals of the same sex are compared, the bill is generally pure yellow 
in adult H. torotoro but has some black in adult H. megarhyncha of 
all races except sellamontis, neither species approaches the other 
morphologically with altitude, and the two forms show independent 
geographic variation in subspecific traits. 

VOICE. A lengthy “police whistle’ identical to the call of H. 


megarhyncha (Fig. 19, p. 186), as also noted by Stein (1936, p. 47). The 
whole body shakes as the bird calls.

WEIGHTY. 63. 

WING. 90. 

EXPOSED CULMEN. ‘To margin of lateral feathering, 38; to margin of medial 
dorsal feathering, 41. 

TAXONOMY. ‘The Eastern Highlands population may eventually 
require separation as a new race nearest nominate megarhyncha but 
larger, but the material available at present is too limited to warrant 
doing so now. Only two other Eastern Highlands specimens have been 
measured: a male, wing given as 96 mm by Mayr and Gilliard (1954, 
p. 343); and male, wing given as 89 mm by Gyldenstolpe (1955, p. 72). 
My measurements of female specimens in the American Museum of 
Natural History yield: nominate megarhyncha, 8 9° from southeastern 
New Guinea, wing 81-88 (83 + 2; seven values fall between 81 and 
83), exposed culmen to margin of medial feathering 36-40 (38.5); 
wellsi, 2 9 from the Weyland Mountains, wing 86 and 87. The Awande 
female thus has a longer wing than any other female measured, and 
this is probably also true of the male listed by Mayr and Gilliard. ‘The 
bill of the Awande specimen is yellow except that the upper surface of 
the upper mandible is black. The bills of H. m. megarhyncha and 
wellst are similar, but sellamontis of the Huon Peninsula has the 
whole bill yellow. The race wells: differs from nominate megarhyncha 
in the buffier, less white underparts and the darker (bluer) back, in 
which respects the Awande bird agrees with megarhyncha. 

BREEDING. ‘The gonads were small, as also true of my sole H. 
torotoro specimen, so that these two resident species presumably breed 
when the migrants H. sancta and H. macleayii are gone. 


DISCUSSION. Halcyon megarhyncha is found strictly in the forest 
interior, from about 4,000 to 6,500 ft. Its altitudinal range is com- 
pletely exclusive of that of its low-altitude sibling H. torotoro, From 
April to September the Australian migrants H. sancta and H. macleayi 
share its altitudinal range but are confined to open country, so that 


188

habitat exclusion is complete. It would be interesting to know ge 
megarhyncha comes out to the forest edge and second-growth when 
the migrant flood departs. 

H. megarhyncha is locally not uncommon, and calls often and loudly 
while perched in the middlestory of forest trees. It must remain motion- 
less inside the foliage, for I found the singers exasperatingly impos- 
sible to see, and Stein (1936, p. 48) and Rand (1942b, p. 460) report 
similar experience. The minimal number of specimens collected in 
the Eastern Highlands reflects this invisibility rather than true rare- 
ness. 

VOICE. A long call identical to the call of H. torotoro, closely 
similar to a police whistle in quality, and consisting of a series of rapid 
notes lasting a total of several seconds. The pitch may continuously 
drop throughout the series; may initially rise before dropping; or may 
drop, then rise, and sometimes drop again (Fig. 19, p. 186). How /. 
torotoro and H. megarhyncha, which are so similar both in appearance 
and in voice, distinguish each other near the transitional altitude is 
unknown.

STOMACH CONTENTS. Insects and a frog. 

TAXONOMY. All eight specimens have the blue-green backs of 
the race incincta, a migrant from eastern Australia. At Nondugl, 
Gyldenstolpe took two specimens, one of imcincta and one of the resi- 
dent eastern New Guinea race elisabeth. In addition, I saw but did 
not collect the species at Okasa (4,250 ft), and Schodde and Hitchcock 
met incincta at Lake Kutubu (2,450 ft). 

BREEDING. All specimens had small gonads. 


DISCUSSION. Of the two Halcyon species that migrate to New 
Guinea during the Australian winter, H. sancta is common up to 
7,500 ft, whereas H. macleayit becomes uncommon above 5,000 ft and 
apparently disappears above 5,500 ft. Below 5,000 ft both may be 
found at the same locality, but H. sancta is up to twice as common. I 
can discern no differences in wintering habitat preferences where they 
overlap at these lower altitudes. Both species choose open habitats 
with trees in which they perch 5-40 ft above the ground, most often in 
native gardens, and eschew the forest and even the forest edge. In 
flight I find the white wing patches of H. macleayii a useful field mark. 

VOICE. ‘The migrant incincta was silent during the time I ob- 
served it in the Eastern Highlands. ‘The call of the resident elisabeth

DISCUSSION. ‘The sex ratio of the specimens (15. 4/2 2) as quite 
disparate in this Australian wintering visitor. Other collections have 
often shown equally disparate ratios. For instances, Gyldenstolpe (1955, 
p. 75) obtained 0 ¢, 8 ¢@ at Nondugl; the Second Archbold Expedi- 
tion (Rand, 1942a, p. 321) had a total of 0 4,6 @ at three localities, 
2 4,0 Q ata fourth; the Third Archbold Expedition (Rand, 1942b, 
p. 461) had 10 ¢, 3 9. It appears that males and females may have 
different local preferences in their wintering grounds. 

Of the migrants that visit the Eastern Highlands during the 
Australian winter, this is the commonest species above 5,000 ft, and 
one of the commonest below this elevation. All observers have found 
it at most localities in suitable habitats up to 7,500 ft from April 
through October. As stated under H. macleayii, it is to be found in 
open habitats with trees, such as native gardens, around human habita- 
tions, and in casuarina stands, never inside the forest. Much smaller 
numbers must have reached the Eastern Highlands before the spread 
of native agriculture. Insects are caught by pouncing, occasionally in 
midair by sallying, and are killed by being pounded against a surface. 

VOICE. Usually silent; occasionally, a soft rasped note. 


Tanysiptera galatea subsp. 
Common Paradise Kingfisher 


STOMACH CONTENTS. Insects. 


DISCUSSION. Dr. Bulmer has kindly informed me that natives 
reported racket-tailed kingfishers, probably of this species, as not un- 
common in the Jimmi Valley, that he examined plumes procured by 
natives, and that N. Camps collected one specimen. ‘The species is to 
be expected at the lowest elevations along the edges of the Eastern 
Highlands. 

New Guinea has two common lowland forest kingfishers which are

in related genera and ecologically somewhat similar: Tanysiptera 
galatea and Halcyon torotoro. They differ ecologically in size (average 
weight of the former 56 g, the latter 41 g), vertical preference (the 
former more confined to the understory), and upper altitudinal limit 
(the latter extending to higher altitudes). 

VOICE. The call is a slow, soft, upslurred, mournful whistle last- 
ing 2-3 sec and repeated at intervals. The song is a loud, rising, ac- 
celerating, whistled trill usually preceded by a longer, more nasal note 
(Bie: 19, p. 1c6):

STOMACH CONTENTS. Insects. 

TAXONOMY. Five specimens have black throats (an adult char- 
acter), five do not (an immature character); four have elongated tail 
feathers (an adult character), six do not (an immature character). 
There seems to be no fixed sequence for acquisition of the black throat 
and long tail: four specimens with black throats have short tails, three 
with long tails lack black throats, one has both a black throat and 
long tail, and two have neither. 

BREEDING. All specimens had small gonads. 

DISCUSSION. As in the case of Halcyon sancta, the sex ratio is 
quite disparate (2 ¢,7 ?). This has also been true for the specimens 
collected by some other expeditions in New Guinea, suggesting some 
segregation of the sexes on the wintering grounds. 

This Australian wintering visitor has also been recorded from April 
through at least August by Gilliard in the Wahgi Valley and by Bulmer 
in Kyaka territory and in the Schrader Range. Schodde and Hitchcock 
found it appearing at Lake Kutubu in early October and following the 
Soro River, evidently at the beginning of the return migration to 
Australia. In suitable habitats M. ornatus is not uncommon below 
4,500 ft and locally up to 5,200 ft, above which altitude it seems rare 
or absent. It apparently may gather in roosts, since flocks regularly 
fly in one direction just after sunrise and return in the opposite direc- 
tion towards sunset. Its habitat preference is large expanses of open 
country with a scattering of trees to provide exposed perches (never 
in the forest interior). From these exposed perches it sallies out like a 
flycatcher, or soars and floats like a swallow, in a short flight, before 


19] 


SPECIES ACCOUNTS 


returning to the perch. The flights in a smooth arc remind me of the 
motion of a model airplane attached to a fixed length of cord. Merops 
ornatus sometimes circles in a breeze with spread wings for several 
seconds without flapping, and may be one of the smallest birds that 
actually soars. 

VOICE. -A: single musical note (‘bk’); or three or four such notes 
run together in very rapid succession.

STOMACH CONTENTS. Insects up to several centimeters in length. 

TAXONOMY. At Karimui both the resident breeding form waigi- 
ouensis and the Australian wintering visitor pacificus occurred, with 
the former far more numerous. The sole specimen obtained at Solia- 
beda was pacificus, as was the sole bird Schodde and Hitchcock col- 
lected at Lake Kutubu. Bulmer collected both races in Kyaka territory. 
With practice these two races can be distinguished in the field by the 
darker and richer coloration, bluer underparts, and greener upperparts 
of waigiouensis and by the paler, browner color of pacificus. ‘Vhe larger 
size of waigiouensis appears most clearly in the weights. 

BREEDING. All specimens of both races had small gonads. As dis- 
cussed by Mayr (1942, p. 253), crossing of these races is prevented 
because pacificus remains in nonbreeding condition while in New 
Guinea. The small gonads of all my waigrouensis specimens as well 
suggest that waigiouensis is also in nonbreeding condition (like most 
species of second-growth in the Karimui area) when pacificus arrives, 
and breeds in the rainy season after the latter’s departure. A Novem- 
ber-December breeding season of waigiouensis in southeastern New 
Guinea is also suggested by the records of the First Archbold Expedi- 
tion (Mayr and Rand, 1937, p. 88). In addition, although both races 
do sometimes occur at the same locality, usually one or the other 
race vastly predominates. 

DISCUSSION. ‘The Dollarbird was generally solitary and selected 
exposed perches in the tops of tall, dead or leafless trees overlooking 
open spaces, in partly cleared forest or near the edge of the forest, in 
the manner of a giant flycatcher. From these perches it periodically

sallied out and circled around with a floppy, caprimulgid-like flight 
before returning to the perch. Once a display was observed between 
two birds perched in a tree, which bowed to each other rhythmically 
for a minute before flying off together. Circling flights observed in the 
morning at considerable heights may also constitute a display. 

VOICE. A short, low-pitched, monosyllabic croak or snapping 
sound reminiscent of a frog or insect, and somewhat suggestive in 
quality of the disyllabic call of Mino dumonti. 


BUCEROTIDAE: HORNBILLS

WING. 2 @: 487 (a), 415 (b). 

TAIL, 1-4: 232%(b): 

TAXONOMY. ‘The race junge: from eastern New Guinea was sep- 
arated from ruficollis of western New Guinea on the basis of larger 
average size apparent in long series, but there is a good deal of overlap 
(Mayr, 1937, p. 13). Since the wing length of males averages 424 mm 
in ruficollis but 442 mm in jungei, the present scanty material (aver- 
age 426 mm) must be assigned to the smaller ruficollis. A male from 
Lake Kutubu had a wing of 420 mm and was also assigned to ruficollis 
by Schodde and Hitchcock. 

BREEDING. Both specimens had small testes. 

DISCUSSION. In the Karimui area this species was uncommon 
and was usually seen singly or in pairs in the forest. Hornbills prob- 
ably are widely distributed at low elevations (below ca. 3,500 ft) at the 
edges of the Eastern Highlands. 

VOICE. A series of grunts, “uh----uh----uh----uh”; in flight, a thump- 
ing or chugging sound made with the wings at each beat, as of a steam 
locomotive slowly starting up.

‘TAXONOMY. ‘The New Guinea races are quite distinct, and the 
present series agrees well with macklotii from southeastern New 
Guinea and the Fly River. The race habenichti differs in the brighter, 
redder, less brown nape; loriae in the very dull brown nape which 
hardly contrasts with the darker brown of the crown; and oblita in the 
paler, less bright nape and the bluer, less green back. The five young 
birds have the belly lighter and more rose-orange in color, the throat 
and breast mottled brown, and only scattered bright feathers on the 
nape. 


BREEDING, ‘The gonads were enlarged in the Soliabeda pair but 
small in all other specimens. This fact, combined with the number of 
young birds, suggests that (except at Soliabeda) breeding was recently 
completed, i.e., before the dry season. 

DISCUSSION. Pitta erythrogaster is widely distributed in forest 
on the hill slopes up to 3,500 or 4,000 ft. Natives said that it lived on 
the ground in the forest interior, and Paran encountered it in small 
parties of about three birds on the forest floor. 

VOICE. According to Daribi natives, the call consists of two low- 
pitched, slow, tremulous whistles, the first rising in pitch, the second 
falling in pitch. 


Pitta sordida novaeguineae Miller and Schlegel 
Black-headed Pitta 


This pitta, whose altitudinal spread upwards from the lowlands is 
much more limited than that of P. erythrogaster, is known in the 
Eastern Highlands only from the Jimmi Valley of the northern water- 
shed, where Mayr and Gilliard (1954, p. 343) recorded one specimen 
and Bulmer (pers. comm.) collected three more. 


ALAUDIDAE: LARKS 


Mirafra javanica subsp.

DISCUSSION. ‘This grassland species was collected in the Batyer 
Valley by J. Kikkawa. It has been recorded at only four other localities

VOICE. The call note has the quality of the sound produced by 
running one’s finger along the teeth of a comb, as does the call of 
Peltops montanus.

TAXONOMY. ‘These specimens differ from nominate sloeti: of

thirds of the crown washed with yellow-green. 

BREEDING. ‘The gonads were small in all specimens, suggesting 
breeding in the rainy season, as with most other campephagids. 

DISCUSSION. Campochaera, a monotypic and endemic New 
Guinea genus, has a very spotty distribution on the lower hill slopes 
and near the foot of the hills. ‘he population in the Karimui area is 
at present the only one known in the Eastern Highlands, and is about 
1,000 ft higher than the usual altitudinal ceiling of the species. Be- 
sides collecting it at Karimui and Bomai, I observed it at Soliabeda. 
Its habitat in the Karimui area was tall trees in forest and at the edge 
of forest, especially trees bearing fruit, while the duetting displays 


195 


SPECIES ACCOUNTS 


were carried out in the crowns of the tallest trees emerging above the 
canopy. Ogilvie-Grant (1915, p. 121) remarked that “it appeared to 
have the habits of a Flycatcher, darting out to catch some passing in- 
sect and returning again to the same perch”, but this description could 
well have been based on the conspicuous duetting display and it may 
not have been catching insects at all. 


VOICE. A duet which has been described in detail elsewhere 
(Diamond and Terborgh, 1968). Briefly, one individual delivers a 
rapid series of a half dozen high, musical notes, all on the same pitch. 
Simultaneously with the last several notes, a second individual gives 
a whistled upslur, downslur, or two or three slurs. In groups of two 
to four the brightly colored singers move through the canopy, repeat- 
ing the performance from the tops of trees successively several hundred 
feet apart. This display is similar to that of Coracina montana and 
C. schisticeps. 


Lalage atrovirens subsp.

STOMACH CONTENTS. Fruit up to 4 mm in diameter, and insects. 


DISCUSSION. Bulmer collected two specimens in the Jimmi Val-

the northern watershed. It lives singly or paired in the treetops, more 
often in light forest or at the forest edge than in primary forest. 

VOICE. Emphatic upslurs or groups of 5-7 notes reminiscent of 
laughter, repeated 3-9 times (Fig. 20, p. 207).

TAXONOMY. Rand (1942a, p. 324) has discussed individual 
variation in this race. My two adult males resemble southeastern New 
Guinea birds in their gray, distinctly barred underparts and are 
slightly more barred than one topotypical polygrammica male from 
the Aru Islands. Eleven out of 14 males from the Fly River area are 
nearly whitish below with the barring very obscure, and the remain- 
ing ones are comparable to southeastern New Guinea males. 


BREEDING. ‘The gonads were small in all specimens. 


DISCUSSION. ‘This is the triller of the southern watershed, occur-

served it once at Okasa. Its habitat was the middle- and upperstories 
(20-100 ft above the ground) of trees at the edge of forest, 1m partly 
cut forest, and in isolated tall trees, not in the well-shaded forest 1- 
terior. It was usually seen in pairs and moved about in leisurely fash- 
ion. 

VOICE. ‘The only sound I heard was, on one occasion, a scolding 
downslurred note similar to that of the honeyeater Melilestes mega- 
rhynchus, 


Niche Differences in the Genus Coracina 


This large genus is represented in New Guinea by I1 species, of 
which 10 have been reported from the Eastern Highlands. All live in 
the middle- and upperstories (I have yet to take any member of the 
genus in a mistnet). All species take both insects and fruit, but C. 
schisticeps, C. montana, C. boyeri, and perhaps C. lineata take mainly 
fruit, while C. tenuirostris, C. caeruleogrisea, C. papuensis, C. longi- 
cauda, and perhaps C. melaena and C. morio, take mainly insects. 

Three of the species are large (weights 95-150). One of these, C. 
novaehollandiae, is an Australian winter visitor of which only strag- 
glers reach the Eastern Highlands and remain in open habitats. ‘The 
other two are forest species whose altitudinal ranges are nearly mutu- 
ally exclusive: C. longicauda at higher elevations, where it encounters 
only the somewhat larger C. caeruleogrisea and the considerably 
smaller C. montana near the lower limit of its range; and C. caeruleo- 
grisea at lower elevations, where it overlaps several congeners half its 
size. 

The remaining seven species are small (50-70). Two of these (C. 
tenuirostris and C. papuensis) are low-altitude species which are usu- 
ally found in open and forest edge habitats. Of the five small forest 
species (C. montana, C. schisticeps, C. morio, C. melaena, C. boyert) 
two have mutually exclusive altitudinal ranges: C. montana at higher 
elevations, above not only C. schisticeps but also above the three other 
small forest species; and C. schisticeps at lower elevations. ‘The dis- 
tributions of C. schisticeps and C. morio in the hill forests (ca. 1,500- 
4,500 ft) tend to be locally complementary, and both are uncommon 
at sea level, where the common forest species are C. melaena in the 
middlestory and C. boyeri in the crowns. C. melaena and C. boyeri 
have altitudinal ceilings lower than the ceilings of C. schisticeps and 
C. morio but overlap these two hill forest species to a considerable 
extent. Unsolved problems are how these four small forest species sort 
out on the lower hill slopes, and what habitat differences C. schisticeps 
and C. morio recognize to achieve partly complementary local dis- 
tributions.

TAXONOMY. The races C. m. melaena of western New Guinea and 
meeki of eastern New Guinea differ in darkness of the female and in- 
tergrade clinally, melaena being the darker race. The backs of my fe- 
males are quite richly colored and compare well with nominate me- 
laena from the Vogelkop and Idenburg River. The undersurfaces of 
meeki females from southeastern New Guinea are paler, more cinna- 
mon, less richly colored than in nominate melaena. In this respect Fly 
River birds (assigned to meeki) are intermediate; my females are on 
the average more richly colored than the Fly River birds and are 
nearly as richly colored as Vogelkop and Idenburg River females. This 
gives a checkerboard distribution as one proceeds from west to east 
on the south coast: melaena from the Vogelkop to the Eilanden River, 
meeki at the Fly River, melaena at Karimui, and meeki in the south- 
Casts 


BREEDING. One Karimui female had enlarged ovaries, but the 
gonads were small in all other specimens. 


DISCUSSION. In the Karimui region Coracina melaena is some- 
what above its usual altitudinal ceiling and was nearly as common as 
its much noisier close relative Coracina schisticeps, with which it 
sometimes occurred in the same tree. C. schisticeps and C. melaena 
differ somewhat in altitudinal preference, C. schisticeps having a 
higher ceiling, and C. melaena being common in the flat lowlands 
where C. schisticeps is uncommon or absent. At Lake Kutubu (2,450 
ft) Schodde and Hitchcock found C. melaena common and did not 
obtain C. schisticeps. C. melaena spends more time in the middlestory 
(15-40 ft above the ground), C. schisticeps and C. boyeri in the crowns.

female’s chin is rufous rather than gray; in addition, in reichenowt 
the male’s chin is darker. Compared to poliopsa females from south- 
eastern New Guinea, the Fly River, and the southern slope of the 
Snow Mountains, Soliabeda females differ in the deeper and richer 
rufous of the underparts, and in the greater extent of gray on the 
chin. It seems desirable to await more material from the Eastern High- 
lands to decide whether the chin color is sufficiently consistent to 
warrant racial separation. ‘The deep rufous underparts of Soliabeda 
females are unlikely to be a racially significant character, since com- 
parison of recent and older collected material from the same locality 
shows that this ventral color is subject to postmortem fading. 

BREEDING. ‘The gonads were small in all specimens. 

DISCUSSION. Coracina schisticeps has not yet been recorded from 
the northern watershed of the Eastern Highlands and is “inexplicably” 
missing from the Huon Peninsula and most of the southeastern New 
Guinea. At Karimui and Soliabeda it was common and conspicuous 
in the treetops, accounting for about 5% of bird individuals. 


VOICE. As described elsewhere (Diamond and ‘Terborgh, 1968) 
groups of two to four C. schisticeps carry out treetop displays similar 
to those of C. montana and Campochaera sloetit, except that the fe- 
male does not reply to the male’s vocalizations and there is therefore 
no duet. The male’s call is a series of loud, nasal, whistled slurs similar 
to those of C. montana males, the first one upslurred, later notes down- 
slurred. ‘his conspicuous performance is repeated from the tops of 
different tall trees. 


Coracina tenuirostris subsp.

DISCUSSION. Bulmer collected two specimens (one each at 4,200 
and 5,000 ft) in the Baiyer Valley and one at 5,000 ft in the Jimmi Val- 
ley. This species lives at the forest edge and in gardens and second- 
growth. 

VOICE. ‘The song is a series of identical clear notes repeated at 3 
times per second for 10-30 sec and crescendoing slightly. One or two 
other birds may fly into a treetop with a singer and give musical chirps, 
but the group display is less ritualized than in the case of C. schisticeps 
and C. montana.

TAXONOMY. The Okasa female, presumably a young bird, has 
the axillaries nearly white with gray barring, a condition that can be 
matched in some specimens available for comparison. It also has very 
faint suggestions of barring on the belly. 


BREEDING. All specimens had small gonads. 


DISCUSSION. There is some tendency, though not a strict one, 
for the local distributions of Coracina morio and C. schisticeps in the 
hill forest to complement each other, just as the distributions of C. 
montana and C. schisticeps complement each other altitudinally. ‘This 
is reflected in the fact that I collected no C. schisticeps at the three 
localities where I took C. morio, and no C. morio at the two localities 
where I took C. schisticeps. 


VOICE. C. morio is apparently the author of a song consisting of 
a buzzy note repeated at 5 times per second for about 4 sec, suggestive 
of the song of C. tenuirostris.

127-137 ¢). The present series belongs to the smaller eastern popula- 
tion, but minus is now not recognized because size decreases clinally 
from west to east on the Central Range (Diamond, 1969; Rand and 
Gilliard, 1967). The two largest males (wing 135) came from 8,000 ft 
on Mt. Michael, whereas all other measured males came from altitudes 
of 4,000-6,000 ft. Other than this I cannot discern an increase in size 
with altitude. In the Snow Mountains, Rand (1942b, p. 463) also found 
that birds from 9,200 ft were distinctly larger but that there was no 
correlation between size and altitude between 4,000 and 7,200 ft. The 
Okasa immature male, which has the shortest wing of the series and 
a low weight, has the tail, primaries, and lores, but not the chin, 
throat, or breast, black; there are scattered black and white barred 
feathers (dark subterminally, white terminally) on the head, cheeks,

and belly, and the tips of the secondaries and undertail coverts are 
barred black and white. The unsexed Awande specimen, which also 
has a short wing and low weight, is similar except that the tail in addi- 
tion has white tips and the barring on the body is more limited. Rand 
(1942b, p. 463) describes an immature male in similar plumage, and 
the American Museum of Natural History has a few other similar 
specimens. 

BREEDING. ‘The gonads were small in most specimens but were 
slightly enlarged in four males and one female from Mt. Karimut. 

DISCUSSION. ‘This is a conspicuous and widespread species in 
mountain forest between about 4,000 and 9,000 ft, living in the crown 
of the forest (not in second-growth). The lower limit to its range is 
fixed by competition with its low-altitude congener, C. schisticeps: 
the altitudinal ranges of these two species are mutually exclusive, and 
I have not detected either species penetrating the other’s altitudinal 
zone by more than 100 vertical feet. Thus, in the Karimui area C. 
schisticeps was common up to 4,200 ft, above which it disappeared 
completely, while C. montana was common above 4,230 ft, with a 
single observation at 4,140 ft. In contrast to the sharp lower limit, C. 
montana becomes gradually less common at higher altitudes de- 
pending locally on the elevations at which the forest becomes stunted 
and tall trees disappear. On Mt. Karimui, where the forest became 
heavily mossed at 6,500 ft and progressively more stunted thereafter, 
C. montana accounted for about 10% of all bird individuals at 4,200- 
5,800 ft, about 5% at 5,800-7,280 ft, and was absent above 7,280 ft. 
On Mt. Michael, where heavy moss and stunting set in only at 8,700 ft, 
C. montana was still common around our camp at 8,000 ft. but was 
only encountered once above 8,700 ft. 

VOICE. A loud and precisely synchronized duet which is delivered 
in the treetops by parties of two to four birds and has been described 
elsewhere (Diamond and ‘Terborgh, 1968). The female delivers several 
harsh notes on the same pitch in synchrony with slurred whistles from 
the male. Each day the singers follow apparently the same route, se- 
lecting display trees several hundred feet apart.

BREEDING. All specimens had small gonads. 

DISCUSSION. This graybird lives in small parties of three to five 
birds in the treetops. The Karimui population may represent an alti- 
tudinal record for this lowland species, and the only other Eastern 
Highlands record is provided by one specimen from Lake Kutubu 
(25450 it). 

VOICE. C. boyeri has a display similar to that of C. montana and 
C. schisticeps, in which a group of birds flies among the tops of tall 
trees, stopping in each to call. The display vocalizations consist of 
single or paired, high, sweet, whistled slurs “tsyew,’ more often up- 
slurred than downslurred, repeated at intervals of several seconds. 


Other quieter calls are a low clucking, a cat-like “mew,” and repeated 
chirping notes “chuck.”

TAXONOMY. ‘The race adamsoni of southeastern New Guinea 
differs from strenua of western New Guinea in its larger average size, 
slightly darker ochraceous axillaries, and slightly paler gray general 
coloration. My measurements of wing length give: for adamsoni from 
southeastern New Guinea, 5 g, 171-180 (177 + 4), 49, 163-170 (167 =

as adamsoni while the material from the Karimui area (100 miles to 
the west) is as small as strenua. ‘The Awande-Okasa material ap- 
proaches strenua in the paleness of the underwing coverts. Gilliard 
and Gyldenstolpe assigned their Wahgi Valley material to strenua.

SPECIES ACCOUNTS 


Evidently the populations of this species are nearer adamsoni in the 
easternmost part of the Eastern Highlands and are nearer slrenwa 
farther west. C. c. caeruleogrisea of the Fly River and Aru Islands 1s 
generally paler. 

BREEDING. All specimens had the gonads small. 

DISCUSSION. ‘This large cuckoo-shrike is widespread but not nu- 
merous throughout the Eastern Highlands from about 3,000 ft to a 
ceiling varying locally between 5,200 ft (Mt. Karimui) and 8,000 ft 
(Mt. Michael), and has been met by most observers. ‘Vhe other large 
New Guinea cuckoo-shrike, C. longicauda, has an altitudinal range ly- 
ing mostly above that of C. caeruleogrisea but not completely exclusive 
of it. Like other Coracina species, C. caeruleogrisea lives in the upper- 
story of the forest in small groups of about three birds. It walks along 
tree limbs in a manner reminiscent of a crow. 


VOICE. Varied, with both quiet and louder calls: a harsh, grating 
scream, fairly but not very loud; a soft “chirp”; and a soft slurred 
note first dropping then rising again in pitch, with a mewing quality, 
like the call of the bowerbird Ailuroedus crassirostris.

TAXONOMY. ‘These Australian migrants belong to the eastern 
and southern Australian race melanops, not to the ‘Tasmanian race 
novaehollandiae or the northern Australian race didima, which have 
also been recorded from New Guinea. C. n. didima differs in its 
shorter wing and paler color, C. n. novaehollandiae in its shorter bill. 


BREEDING. ‘The gonads were small in all specimens. 


DISCUSSION. ‘This is the first record of this Australian migrant 
for the Eastern Highlands or for such high altitudes anywhere in New 
Guinea. Small flocks of two to six birds were seen on six occasions at 
Awande, Karimui, and Bomai in isolated tall trees in open country, 
i.e., in gardens and near Karimui airstrip, a habitat in which no spe- 
cies of Coracina resident at Karimui or Awande was ever seen. These 
may have been itinerant groups which remained for short periods, 
since all my sightings in the Karimui Basin fell in the periods 4-14 
Aug. 1964, and 8-11 July 1965.

Coracina papuensis subsp. 
Papuan Graybird 
STOMACH CONTENTS. Insects (no fruit). 


DISCUSSION. ‘This non-forest campephagid is generally a low- 
land species in New Guinea but has colonized two widely separated 
areas of the Eastern Highlands. At Lake Kutubu (2,450 ft) Schodde 
and Hitchcock found it common in flocks at the forest edge and in 
second-growth along the lake. Bulmer found it breeding commonly 
in gardens and open country of the Baiyer Valley up to 5,500 ft. The 
flight is distinctively undulating; the bird alternately flaps to gain alti- 
tude, then glides down with the wings held stiffly vertically down- 
wards. 

VOICE. A weak, high-pitched, disyllabic note “chee-yu” or “whe- 
chew,” the first note higher than the second, with a squealing or breezy 
quality more like the voice of a parrot (e.g., Domicella lory) than of 
most graybirds. 


Coracina longicauda grisea Junge

SPECIMENS EXAMINED. Agotu (Gimi territory): 1 ¢ (22 July 1964). 

WING. 176. 

STOMACH CONTENTS. Large insects (four stomachs); insects and fruit (five). 

TAXONOMY. The races grisea of western New Guinea and nom- 
inate longicauda of southeastern New Guinea differ only in size. I 
measured wings of males of both races, with the following results, 
proceeding from west to east: Snow Mountains (grisea), 171, 172, 173; 
Telefolmin, 170, 173; Mts. Hagen and Wilhelm, 172, 173, 174; Agotu, 
176; Huon Peninsula, 176; southeastern New Guinea (C. J. longi- 
cauda), 177, 179, 180, 180, 186 (180 a= 3). There is obviously a climal 
increase in size from west to east, as shown previously by the more 
extensive measurements of Gilliard and LeCroy (1961, p. 46). Five 
males from the Wahgi region, slightly farther west than Agotu, mea- 
sured by Gilliard and LeCroy (1961, p. 47) and by Gyldenstolpe (1955, 
Dp 77), gave 169; 172, 172,174, 076, yielcine am averaseror N7omter all 
six Eastern Highlands males. On this basis I refer the whole Eastern 
Highlands population to grisea. More specimens would be required 
to decide if birds at the eastern end of the Eastern Highlands really are 
nearer nominate longicauda. 

DISCUSSION. My sole encounter with this species was in forest 
near Agotu, where a tongue of moss forest descended to about 5,800 ft, 
giving this unusually low record for the species. ‘Mhe specimen was one 
of a flock of six hopping slowly along branches in the tree crowns. Most 
other observers in the Eastern Highlands have encountered C. longi-

up to 10,500 or even 12,000 ft.

papuensis, and a short low-pitched chirp. 


MOTACILLIDAE: PIPITS and WAGTAILS 
Motacilla cinerea caspica (Gmelin)

Gyldenstolpe met this palearctic wintering visitor a few times in 
August in boggy grassland at Nondugl. Bulmer observed and collected 
it near streams in Kyaka territory during December through February 
at 4,000-5,500 ft and also commonly in the Schrader Range up to 
7,500 ft. 


Anthus gutturalis rhododendri Mayr 
Alpine Pipit 

SPECIMENS EXAMINED. Mt. Michael: 3 ? (10 July 1964). 

WING. 2 7: 92, 95. 

STOMACH CONTENTS. Insects (five stomachs), grass seeds (two), insects and 
seeds (three). 

TAXONOMY. ‘The Mt. Michael specimens are smaller than nomi- 
nate gutturalis of southeastern New Guinea and have the abdomen 
slightly darker; wollastoni of western New Guinea has the black mark- 
ings on the side of the throat reduced or absent. 

DISCUSSION. ‘This high-altitude pipit was met only in alpine 
grassland at 12,000 ft near the summit of Mt. Michael where, during 
our brief experience in this habitat, it was the only conspicuous bird. 
It walked on the ground with a waddling gait, and perched in bushes 
in the grassland and in 40-ft trees at the forest edge. Alpine grassland 
has now been surveyed ornithologically on four high peaks of the 
Eastern Highlands (Mts. Michael, Wilhelm, Hagen, and Giluwe), and 
Anthus gutturalis has been found on all four. 

VOICE. ‘The varied song consists of high, thin, clear notes, each 
repeated several times before repeating a different type of note. ‘The 
call is a faint, high-pitched “tsip” or “‘tsee,’’ sometimes repeated.

at Tarabo (6,000 ft), but nowhere else. Other observers have found it 
numerous at a number of Eastern Highlands localities between 4,000 
and 7,000 ft in very close-cropped grass, such as on sheep pastures, 
football fields, airstrips, and lawns. The erassland on grown-over native 
gardens seems too tall for it. Elsewhere in New Guinea it has been 
recorded only near Wau and Port Moresby.

TAXONOMY. ‘These specimens are closest to brevtrostris, from 
which they differ only in the darker, blacker crown (tendency towards 
nigriceps). In the pale color of the underparts they are closer to brevi- 
rostris from southeastern New Guinea than from the Fly River; the 
latter are browner below. ‘The races nigriceps and beccarii have duller 
and darker backs, and nigriceps in addition is darker and grayer below. 

DISCUSSION. D. superciliaris is a shy and uncommon, but wide- 
spread, inhabitant of the forest floor from about 1,800 to 4,200 ft. I 
never saw it in life but heard its song several dozen times at Okasa, 
Soliabeda, Karimui, and on the lower slopes of Mt. Karimui. 

VOICE. An unmistakable series of clear, very slow, chromatically 
descending, somewhat plaintive, whistled notes. The quality and the 
medium pitch are similar to those of Crateroscelis murina. In the 
Eastern Highlands the song consists typically of five notes, each lasting 
11% sec and separated by an equal pause from the next mote; so that 
the whole song lasts about 15 sec. ‘he first note is initially down- 
slurred. Successive notes each remain on constant pitch, and each is 
about a half-tone lower than the next (Fig. 20). ‘he downslurred first 
note is sometimes given alone as a call, and takes more practice to 
identify but is still diagnostic.

grassland) almost anywhere in the Eastern Highlands. Solitary in- 
dividuals or pairs perched on fences, dead branches, the ground, and 
at the tops of isolated trees, whence they periodically sallied out in 
flycatcher fashion. One was seen with a berry in its bill. Males showed 
territorial behavior, frequently singing from conspicuous perches gen- 
erally 10 to 30 ft, sometimes as much as 70 ft, high. 


VOICE. <A weak, somewhat hoarse, high-pitched, whistled song of 
four to eight notes in irregular rhythm. Each singer has several pat- 
terns, each of which is delivered several times in succession (with 
moderate pauses between repetitions) before proceeding to the next 
pattern. One of these four-note patterns is the source of the Fore name 
“pobogile.”

TAXONOMY. The Mt. Karimui specimen was compared with 
brevicauda of southeastern New Guinea, olivascentior of the Snow 
Mountains and Weyland Mountains and North Coastal Range, nomi- 
nate incerta of the Vogelkop, and one Mt. Goliath specimen referred 
to brevicauda. ‘Vhe color of the underparts is grayest and dingiest, least 
brown, in olivascentior from the Weyland Mountains and North 
Coastal Range, followed by Snow Mountains olivascentior; south- 
eastern New Guinea brevicauda is browner, and Vogelkop A. 1. incerta 
brownest, least gray. The Mt. Karimui specimen is intermediate be- 
tween Weyland Mountains and Snow Mountains birds. The Mt. 
Goliath specimen is slightly browner than the Mt. Karimui specimen 
but still much less brown than southeastern Drevicauda. ‘The white 
feathers on the side of the throat are conspicuously tipped with dark 
in Weyland Mountains and Snow Mountains birds and the Mt. Kari- 
mui specimen but not in southeastern birds or the Mt. Goliath speci- 
men. The Mt. Karimui specimen is therefore assigned to olivascentior 
on the basis of the ventral coloration and throat feathers. Its wing and 
tail lengths are shorter than those of 10 male olivascentior measured 
(wing 77-84, tail 55-61). Gyldenstolpe assigned his seven specimens from 
the Wahgi Valley to brevicauda, apparently on geographical grounds 
and without comparison of material. He specifically mentions, however, 


208 


SPECIES ACCOUNTS 


the dark margins of the throat feathers, so that they undoubtedly 
belong to olivascentior. The measurements he reports (e.g., wing 79-82 
in males) are comparable to Snow Mountains and Weyland Mountains 
olivascentior. ‘Vhe allocation of the single Mt. Goliath adult is uncer- 
tain. In his check list Mayr (1941) includes the Sepik Mountains in the 
range of brevicauda, presumably on the basis of one specimen which 
Biirgers collected on the Schraderberg and which I was not able to 
examine. 

The revised ranges of the subspecies are therefore: brevicauda, south- 
eastern New Guinea, Huon Peninsula, and (requires confirmation) 
Schraderberg; olivascentior, Eastern Highlands, North Coastal Range, 
Snow Mountains, and Weyland Mountains; Mt. Goliath (eastern ex- 
tremity of Snow Mountains), allocation uncertain; and nominate 
incerta, Vogelkop. 

BREEDING. ‘The testes of the Karimui specimen were greatly 
enlarged. 


DISCUSSION. My specimen was netted at 5,960 ft, while Gylden- 
stolpe’s specimens were all trapped at 8,000 ft. The only other Eastern 
Highlands records are from the Schrader Mountains (specimens ob- 
tained by Biirgers and Bulmer). This is evidently a rare and local 
thrush of the forest floor. 


Turdus poliocephalus erebus Mayr and Gilliard

STOMACH CONTENTS. Fruit (two stomachs), insects (one), fruit and insects

The Island ‘Vhrush was found in alpine grassland above 1,000 ft on 
the summits of Mts. Hagen, Wilhelm, and Giluwe by Gilliard and by 
Shaw-Mayer. On Mt. Albert-Edward I found it characteristic of the 
edge between forest and alpine grassland, hopping on the ground and 
perching in low bushes or up to 40 ft high in forest edge trees, some- 
times feeding in grassland several hundred feet from the forest edge 
but retreating to the forest when alarmed. 

VOICE. ‘The call-notes are typical for the genus Turdus: a re-

Keku in the Finisterre Mountains of the Huon Peninsula, and pulcher 
from southeastern New Guinea. ‘Topotypical material of bwergersi 
(Sepik Mountains) and par (Saruwaged Mountains) was lacking. 
Females of the races E. c. castanonotus, saturatus, uropygialis, and from 
the Adelberts differ from mine in having the eye stripe blue in all speci- 
mens. The general color of E. c. castanonotus is quite similar, but its 
blue is slightly paler and less purple, and the chestnut of its back is 
very slightly paler. £. c. satwratus differs conspicuously in its much 
deeper blue ventral coloration and its slightly darker chestnut back. 
E. c. wopygialis differs conspicuously in that the lower back of the 
female is blue, not chestnut, and differs slightly in the generally paler 
coloration. The Adelbert series and the Keku males differ in the 
lighter tone both of their chestnut and blue parts. E. c, pulcher is 
quite ‘close ini its general coloration; the blue of pulcher averages 
slightly lighter and less purple, but many specimens can be matched 
with mine; the chestnut averages lighter in pulcher. Females of pulcher 
have the eye stripe pale blue or whitish, often mixed with rusty (none 
of my females has this rusty). From the description (Mayr, 1931, p. 691), 
buergersi is eliminated by the blue eye stripe of all three known 
females and perhaps by its darker general coloration. E. c. par (Meise, 
1930, p. 17) apparently agrees with my specimens in that the eye stripe 


210 


SPECIES ACCOUNTS 


of the female may be either solid blue, or else pale blue behind the 
eye; it apparently differs in its longer wing (the original description 
cited 2 ¢ 101, 101; 2 9 98, 99); Meise said that males of par were 
indistinguishable from saturatus, which would make them much darker 
blue than my specimens; Mayr said that females of par had a lighter 
chestnut back than E. c. castanonotus, which would make them lighter 
chestnut than my specimens. 

The Eastern Highlands series thus shares the variably light eye stripe 
of females of the eastern populations pulcher and par. ‘Vhe small dit- 
ferences in general coloration between it and the slightly lighter 
pulcher to the east are what one would expect of a clinal east-to-west 
darkening along the southern watershed that would culminate in 
saturatus of the Snow Mountains. ‘The incidence of light female eye 
stripes seems also to decrease clinally east-to-west on the southern 
watershed from pulcher through the Eastern Highlands to saturatus. 
The Eastern Highlands population is therefore best assigned to the 
most similar end of the cline, pulcher. 

BREEDING. The gonads were enlarged in all adult males and 
half the females. Evidently this ground nesting species (Rand, 1942a, 


9° OF 


p. 327) breeds in the dry season. 


DISCUSSION. FE. castanonotus lives strictly in the forest interior 
on the ground. Single birds or pairs were occasionally seen walking 
with bobbing head and fairly long, leisurely strides on the forest floor. 
When disturbed, the birds flew just above (i.e., less than 1 ft above) 
the ground and realighted 10-20 ft away, in a manner reminiscent of 
South American tapaculos (Pteroptochos megapodius, Rhinocryptidae). 
‘They were much more often heard than seen. 

While E. castanonotus has yet to be recorded away from the Karimui 
area, it 1s likely to turn up at most stations in hill forest between about 
1,500 and 4,500 ft. The genus Eupetes provides an instance of perfect 
triple exclusion, in that the altitudinal range of E. castanonotus lies 
strictly above that of E. caerulescens (transition at ca. 1,000-2,000 ft, 
E. caerulescens from there down to sea level) and strictly below that of 
E. leucostictus (transition at ca. 4,100-5,000 ft). The evolution of the 
genus is particularly easy to trace, since each species shows consider- 
able subspecific variation in color pattern and some race of each species 
can be found which approaches in its color pattern some race of the 
species above or below it. 

VOICE. ‘The song (Fig. 2la) consists of three to six clear, bell-like, 
whistled notes at moderate pitch, all on the same pitch and identical 
except for dramatically increasing in volume, and concluded by a very 
loud downslurred “chew!” Sometimes a short, unmusical, fainter, 
downslurred “ksew” comes between the whistled notes and the “chew!” 
The whole song takes about 2 sec. On paper this looks like the song 
of several Pachycephala species (P. soror, P. hyperythra, P. rufiventris), 


Zi

but in practice I felt no danger of confusion, possibly because the 
final “chew!” is so distinctive. Heard more often is the common call 
(Fig. 21b), three very loud, identical, explosive notes “chew! chew! 
chew!” in rapid succession. When heard at a distance, this call can 
easily be confused with a similar call of the whistler Pachycare flavo- 
grisea, but that of Eupetes castanonotus is louder, somewhat more 
rapid, and comes from the ground, not from the trees.

TAXONOMY. These belong to the eastern race; brunnea of 
western New Guinea differs by being more brown and less olive above

BREEDING. ‘The gonads were slightly enlarged in two Mt. Kari- 
mui males but were small in other specimens. 

DISCUSSION. Virtually all collectors in the Eastern Highlands 
have found the Ifrit fairly common in primary midmontane forest up 
to about 9,500 ft. Its lower limit is not more than 1,000 ft below the 
lower limit of the mossy zone, at an altitude depending upon local 
conditions (usually 6,500 or 7,000 ft). It feeds nuthatch-like in moss- 
covered trees, probing in moss, pounding at the bark, often bending 
over a branch head downwards to probe the undersurface while still 
gripping the uppersurface with its legs, and bracing itself stiffly on its 
tail. he tip of the tail consequently becomes abraded, as in the case 
of the New Zealand warbler Mohoua ochrocephala, which has similar 
habits. The Blue-capped Ifrit forages from the understory to the crowns

and is often seen in pairs or groups of three, calling frequently and 
loudly. 

VOICE. A rapid series of a half dozen rasped, scratchy, identical

Mohoua ochrocephala. 


MALURINAE: WREN WARBLERS 


The warblers of New Guinea and Australia fall into four groups 
whose relationships are unclear. One group, represented in New 
Guinea by five species in the genera Malurus, Todopsis, Cheno- 
rhamphus, and Clytomyias, is confined to Australia and New Guinea. 
A second, represented in New Guinea by 19 species in the genera 
Sericornis, Acanthiza, Gerygone, and perhaps Crateroscelis, is centered 
on New Guinea and Australia but has a few representatives on islands 
to the east and west. A third consists of grass warblers of predomi- 
nantly Eurasian and African genera, of which Acrocephalus, Megalu- 
rus, and Cisticola have breeding representatives (five species) in New 
Guinea. The fourth consists of the Eurasian and African tree warblers, 
of which only Phylloscopus trivirgatus reaches New Guinea. ‘The third 
and fourth groups comprise the subfamily Sylviinae. While earlier 
authors (and Rand and Gilliard, 1967) placed the second group (Ser- 
cornis and its allies) with the Sylviinae and kept the first group as a 
separate subfamily Malurinae, Mayr and Amadon (1951) and Keast 
(1961) tentatively combine the second group with the Malurinae. ‘The 
latter arrangement is arbitrarily adopted here.

white below (Bomai); a third has a white chin and belly but blackish 
throat and breast (Karimui); and the fourth is largely charcoal brown 
below with scattered white feathers and a whitish chin (Soliabeda). Of 
the three immature males (all from Karimui), one has white lores,

SPECIES ACCOUNTS 


scapulars, and underparts, and the upperparts are black except for 
scattered brown feathers; a second is similar except that the upper- 
parts are charcoal brown; the third is gray-brown above including the 
scapulars, and dirty white below with a darker breast band. ‘The 
juvenile male is charcoal brown above including the scapulars, while 
the underparts and lores are white (Karimui). Both Awande juveniles 
are gray-brown except for a white chin. Adult males are black except 
for white scapulars; one has a few feathers of the belly white but still 
has enlarged testes. The many female and immature Malurus (i.e., 
those apart from the black adult males with white scapulars) seen in 
the field at Karimui were equally variable; some were pure white 
below, others had a dark breast band, and still others were largely 
dark below except for a light throat. 

The color of the females and the large size place this series with 
mafulu, a race described from the midmontane grasslands of south- 
eastern New Guinea and later found in those of the Wahgi Valley. 
M. a. naimii, the lowland race of southeastern New Guinea to the west 
of Port Moresby, differs by its smaller size and on the average by the 
smaller extent of dark areas on the flanks and breast of the female. 
M. a. dogwa of the Fly River lowlands differs markedly in the much 
smaller size, brown upperparts, buffy flanks, and whitish underparts 
without a breast band. Only the Bomai female and the Karimui 
juvenile have any buff on the flanks, and these small amounts can 
be matched in mafulu. It is interesting that in the case of Malurus 
alboscapulatus the newly created grasslands of the Karimui Basin 
have been colonized by the midmontane race (mafulw) rather than 
by the lowland races (naimii or dogwa). 

The Wahgi Valley population was also assigned to mafulu by Mayr 
and Gilliard. Surprisingly, Schodde and Hitchcock (1968, p. 42) state 
that the population at Lake Kutubu (2,450 ft) and Mendi (5,900-7,000 
ft) is very different and they describe it as a new race kutwbu, since 
the female is uniformly sooty black. This pattern is shared by three 
other spatially isolated populations: moretoni in the southeastern New 
Guinea lowland to the east of Port Moresby, aida in the northwestern 
New Guinea lowland and midmontane grasslands of the Weyland 
Mountains, and randi in the midmontane grasslands at the Wissel 
Lakes. The mafulu group (female white ventrally) also has an inter- 
rupted distribution in the midmontane grasslands of southeastern 
New Guinea and the eastern part of the Eastern Highlands (mafuluw), 
the lowlands of southeastern New Guinea (naimiz), the lowlands of 
northeastern New Guinea (tappenbecki), and the Vogelkop (nominate 
alboscapulatus). ‘The third group, in which females are brown and 
white, occurs in the lowlands of southern New Guinea (dogwa) and 
southwestern New Guinea (lorentzi) and the midmontane grasslands 
of the Baliem Valley (balim). An explanation for the checkerboard 
distributions of the three female plumage types is lacking.

SPECIES ACCOUNTS 


BREEDING. Natives brought in two nests, bowls of dry grass 
which were said to have been on the ground in grassland. One con- 
tained one fledgling, the other two. All adult males taken at all my 
collecting localities had greatly enlarged testes. Evidently breeding is 
concentrated in the dry season. According to Fore informants nests of 
Malurus are those most often victimized by the cuckoo Cacomantis 
variolosus. 

DISCUSSION. Malurus alboscapulatus is probably the most abun- 
dant and ubiquitous Eastern Highlands bird in grassland and gardens, 
up to about 7,000 ft. At Soliabeda, where a few years before my arrival 
two small gardens had been cleared in the middle of a large area of 
undisturbed forest, M. alboscapulatus was already common and breed- 
ing though the other characteristic species of the midmontane grass- 
lands had not yet been able to colonize this tiny island of suitable 
habitat. It is usually seen in small groups, perhaps family groups, of 
two to six birds. ‘The birds can readily be called out of the depths of 
the grassland to perches on tall stalks of grass, but I have never seen 
them perched more than 6 ft above the ground. Their flights are 
jerky, brief, and give every impression of being weak, despite which 
they must have crossed nine miles of unbroken forest, including a 
mountain ridge 1,000 ft high, to have reached Soliabeda from the 
nearest grassland. 

VOICE. A rapidly spitted twitter or jumble of notes full of sibi- 
lants, inspiring the Fore name “a-sa-sa-ba.”

DISCUSSION. Schodde and Hitchcock found this low-altitude

edge.

Malurus alboscapulatus.

DISCUSSION. Clytomyias insignis seems to be local and uncom- 
mon in midmontane forest. All four of my specimens were netted, 
indicating preference for the understory. The Fore said that Clytomyzas 
is very similar in behavior to Malurus alboscapulatus and that it goes 
about near the ground and around fallen trees with cocked tail. 


SYLVIINAE: WARBLERS 
Niche Differences in the Genus Sericornis 


‘This genus presents not only difficult taxonomic problems but also 
some of the most complicated altitudinal relationships in New Guinea, 
including parallel four-species and two-species altitudinal sequences 
(Diamond, 1969). Four of the species (S. spilodera, S. arfakianus, S. 
perspicillatus, S. papuensis) are small (weight ca. 9-12), have small 
bills (culmen from base 12-13), forage both in the lower- and middle- 
stories, and constitute a four-species altitudinal sequence. ‘The remain- 
ing two widespread species, S. virgatus (absent in the Eastern High- 
lands) and S. nouhuysi, are large (weight ca. 11-18), have large bills 
(culmen from base 15-16), forage mainly in the lower story, and ex- 
clude each other altitudinally, but each overlaps several of the small 
species. S. beccari is related to S. virgatus but is confined to the flat 
lowlands of southern New Guinea and the Cape York Peninsula of 
Australia, while S. nigroviridis is a mystery bird of distinct appearance, 
known from one specimen. 

The altitudinal ranges of the abundant four small Sericornis species 
on Mt. Karimui were: 


S. spilodera 1,350 ft or below—4,240 ft 
S. arfakianus 4,400 ft —5},000 ft 
S. perspicillatus —6,350 ft 5,100 ft 
S. papuensis —summit (8,165 ft) 6,450 ft 


All transitions were sharp, i.e., no individual of any species was 
caught, seen, or heard in another’s altitudinal band, except for two 
S. spilodera shot together at 4,950 ft, far into S. arfakianus’s band. 
‘These two were young birds with short wings, low weights, and gonads 
not discernible, and conform to the general rule (p. 00) that normal 
altitudinal limits are most likely to be violated by young birds.

TAXONOMY. ‘This series is closest to guilatus of southeastern 
New Guinea and agrees with it in size but differs in the darker throat 
spots, deeper yellow color below, darker upper tail, and darker, 
brighter, and more olive back. S. spilodera thus follows the general 
trend at Karimui towards dark coloration. However, these differences 
seem not sufficiently marked to justify naming a new race. The race 
wurot of the Fly River is paler and greener below, paler and less bright 
above, slightly smaller, and the throat spotting is paler; granti of the 
southern slope of the Snow Mountains is paler below, paler, browner, 
and less olive on the back, tail, and crown, and with paler, browner, 
less gray and less clear throat spotting; nominate spilodera of northern 
New Guinea is paler and less yellow below, darker on the crown, and 
the throat spotting is less dark; ferrwgineus of Waigeu is much paler 
above and below and has the throat spotting nearly obsolete. ‘The 
whole culmen measures 13 to 14 in my specimens. 


BREEDING. At Karimui both in 1964 and 1965, and at Bomai 
and Soliabeda, most males and the one female obtained had greatly 
enlarged gonads, suggesting breeding in the dry season for this species 
of the understory. The sex ratio of specimens for those localities was 
very unequal in favor of males (12:1), as in the case of S. papuensis on 
Mt. Karimui (possibly because females were staying on nests?). In 
contrast, all specimens obtained on Mt. Karimui had very small 
gonads. These individuals near the upper limit of the altitudinal 
range must be young birds or nonbreeding adults, a pattern observed 
in other species as well (cf. p. 30). 

DISCUSSION. _ S. spilodera is the Sericornis species with the lowest 
altitudinal range and is present in hill forest on all major mountain 
ranges of New Guinea, becoming rare or absent at sea level. The 
altitude of 4,240-4,400 ft for the S. spilodera-S. arfakianus transition on 
Mt. Karimui is somewhat higher than usually found elsewhere in New 
Guinea, probably due to the effect of the tropical Karimin Basin 
shifting most hill forest ranges upwards. 

In the field S. spilodera is most easily distinguished from other 
species of Sericornis by its pale, horn-colored bill.

TAXONOMY. The slight geographical variation in this species 
follows an irregular checkerboard that renders impossible the defini- 
tion of subspecies with coherent ranges. In dorsal coloration, popula- 
tions from the Weyland Mountains, Cyclops Mountains, North Coastal 
Range, and southeastern New Guinea are brighter than birds from 
the Idenburg slopes, Adelbert Mountains, and Telefolmin, with 
Vogelkop birds still duller. ‘The underparts range from yellowish with 
slight streaking to grayer with more streaking, the sequence of popula- 
tions from yellower to grayer being Cyclops > Weyland > North 
Coastal Range > southeastern New Guinea > Adelbert Mountains > 
‘Telefolmin, Vogelkop, Idenburg slopes. 

BREEDING. ‘Testes were large in both Okasa males and one of 
the Mt. Karimui males. 

DISCUSSION. This is the second member in the altitudinal se- 
quence of small Sericornis, living above S. spilodera and below S. 
perspicillatus between ca. 4,000 and 5,000 ft. On most New Guinea 
mountains, in my experience and to judge from records of the First 
and the Third Archbold Expeditions (Mayr & Rand, 1937; Rand, 
1942b), its total vertical range is only about 1,500 ft, but even with 
respect to this narrow band its Mt. Karimui range is compressed (to 
600 ft).

BREEDING. ‘Three of the four Mt. Karimui males had greatly

DISCUSSION. 8S. perspicillatus and S. nouwhuysi are superficially 
rather similar because of the yellowish underparts and orange face in 
both species. ‘Ihe iris is generally dull brown in S. perspicillatus, 
whereas it is often red-brown in S. nouhwysi. 

S. perspicillatus is the third in the altitudinal sequence of small 
Sericornis. As with many other birds of midmontane forest, the descent 
of stunted moss forest to 6,500 ft on Mt. Karimui resulted in an 
unusually low upper limit for S. perspicillatus (6,350 ft), and its upper 
limit on most other mountains (e.g., Mt. Michael) is around 8,000 ft.

It flits nervously in small groups of a few to eight birds in the under-

forest interior but also at the forest edge, in partly cut forest, and 
even in casuarina groves which have no bushes in the understory. 


VOICE. ‘The common call is a dry “chip,” recognizable with prac-

of “chip’s’” which progressively rise in pitch and grow thinner in

higher pitch (Fig. 22). There are also scolding and chattering notes.

TAXONOMY. ‘The mark which I find most useful in the hand for 
distinguishing specimens of this difficult and variable species from 
other Sericornis and from Acanthiza murina is on the forehead: for 
2-3 mm from the base of the bill the forehead has the same light orange 
color as the face, with dark tips to the feathers; this contrasts with the 
darker color of the more posterior parts of the forehead and the 
crown. From 8S. perspicillatus, 8. papuensis is distinguished by this 
forehead mark, the subterminal tail band, longer wing, and usually 
by the browner, less olive, coloration, especially on the wings and tail. 
Marks I find useful, besides the forehead, for separating the super- 
ficially similar Acanthiza murina are: the color of the tail (dull gray 
or gray-olive, especially near the tip, in A. murina, brownish-olive in 
S. papuensis; the subterminal tail band (much more distinct in the 
former); the light orange eye ring of the latter, absent in the former; 
the edges of the primaries (olive in the former, often brownish-olive 
in the latter); the whitish chin, speckled with black on the sides, in 
A. murina; and, in life, the dull brown iris of S. papuensis, as opposed 
to the whitish or pale tan iris of A. murina. 

All of my males prepared as skins, and two of my three females, form 
a quite uniform series, showing little variation. “The Mt. Karimui Zone 
5 female from the lower limit of the altitudinal range differs in its 
darker wings and underparts. The Zone 5 immature taken with this 
female is quite yellow below, a feature which can be matched in young 
birds from other parts of New Guinea. Elsewhere in New Guinea this 
is a highly variable species, with plumage varying from brownish to 
greenish. On the average the brownest series are those assigned to the 
race buergerst from the Snow Mountains and Telefolmin (topotypical 
buergersi from the Schraderberg were unavailable); nominate papuen- 
sis from southeastern New Guinea averages more olive, and meeki 
from Mt. Goliath is much greener. ‘The present series is intermediate 
between nominate papuensis and buergersi but closer to papuensis, 
from which it differs mainly in that papuensis averages less dark above. 
Both the more brownish and the more greenish individuals from the 
Snow Mountains have darker underparts than the Mt. Karimui series, 
and no Mt. Karimui specimen is really brown as are many from the 
Snow Mountains. 

The two specimens collected by Gilliard on Mt. Wilhelm and Mt. 
Hagen, which Mayr and Gilliard (1954, p. 347) assigned to buergersi, 
are browner below and duller above than Mt. Karimui specimens. I 
have not seen Gyldenstolpe’s five adults from the Wahgi Valley, which 
he described (1955, p. 93) as being variably browner or greener above 
and which he assigned to buergersi. More specimens of this variable

species would be needed to decide whether Wilhelm-Hagen-Wahgi 


birds really do average browner than those from Mt. Karimui 50 
mules to the south. 


BREEDING. The disparate sex ratio is notable (20 g, 3 9). With- 
out exception all males had greatly enlarged testes. Of the two Zone 6 
females, one had the ovaries enlarged, while I did not record ovary 
size in the other. The two Zone 5 specimens (6,450 ft) were an im- 
mature with undiscernible gonads and a female with small ovaries, 
conforming to the general pattern of nonbreeding birds being found 
at the extremes of the altitudinal range, From 6,550 it up tothe 
summit of Mt. Karimui (8,165 ft) S. papuensis was singing often and 
loudly. 

DISCUSSION.  S. papuensis is the fourth and highest in the alti- 
tudinal sequence of small Sericornis. It foraged from near the ground 
to about 30 ft above the ground in groups of up to four birds, gleaning 
mainly on branches and twigs, rarely on main trunks. 

When I discussed Sericornis ecology previously (Diamond, 1969, pp. 
26-30), I had not had an opportunity to study S. papuensis in the 
presence of Acanthiza murina. ‘The published records of the First 
Archbold Expedition from Mt. Albert-Edward appeared to suggest that 
interaction with A. murina altered the niche of S. papuensis so that the 
latter and S. perspicillatus overlapped in altitudinal range. ‘This proves 
not to be the case, as shown by more recent field work I carried out on 
Mt. Albert-Edward. Despite the presence of A. murina, the ranges of 
S. papuensis and S. perspicillatus there are still nearly mutually ex- 
clusive, as on Mt. Karimui in the absence of A. murina, and overlap 
is confined to a few immature individuals. 


VOICE. ‘The song (Fig. 22, p. 220) is a loud, rapid, unmusical out- 
burst with a somewhat harsh and unclear quality, consisting of five to 
eight notes, all of which are on one of two (occasionally one of three) 
pitches. The song is sometimes prefixed by two or three faint notes. 
The call is a dry “chip” similar to that of other Sericornis species.

TAXONOMY. The Awande and Mt. Karimui series differ in color, 
though not in size. Awande specimens have quite olive backs, rather 
yellow underparts, not dingy on the breast, and are closest to oorti of 
southeastern New Guinea. Mt. Karimui specimens are more rufous 
above, less yellow below, dingier on the breast, and closer to the de- 
scription of stresemanni from the Schraderberg and to the series col- 
lected by Gilliard in the Wahgi region and assigned to stresemannt. 
The race S. n. nouhwysi of western New Guinea is even more rufous, 
while Telefolmin birds were assigned to stresemanni. Evidently there 
is a west-to-east color cline in S. nouhwysi, from more rufous in the 
west to more olive in the east. It seems most convenient to place the 
stresemanni-oort? transition between the Wahgi-Karimui area and the 
Okapa area 100 miles to the east. 

‘The iris is either brown, orange-brown, or red-brown in both males 
and females. 


BREEDING. Gonads were enlarged in only two Awande speci- 
mens, but were greatly enlarged in all Mt. Karimui males and two of 
the females. All five Sericornis species taken in the Karimui area were 
evidently breeding in July, August, and September. At 10,200 ft on 
Mt. Michael an adult was captured on its nest on 10 July 1964. The 
nest was 4 ft above the ground in a bunch of moss hanging from a tree 
limb, and contained two eggs. 


DISCUSSION. S. nouhwysi has been found common by most col- 
lectors at most localities in the Eastern Highlands from about 4,500 to 
11,000 ft or more, in forest and dense second-growth. Compared to the 
four smaller species of Sericornis, S. nouhuysi spends a greater fraction 
of its time in the understory, forages more on main branches and 
trunks than on twigs and small branches, and often works vertically 
up a trunk in the manner of a creeper or nuthatch, probing at the 
bark and moss. ‘The altitudinal range of S. nowhwysit takes in the entire 
ranges of S. perspicillatus and S. papuensis on Mt. Karimui and over- 
laps S. arfakianus at the Sena River and Acanthiza murina on Mt. 
Michael. “The independence of its distribution from that of these 
other small warblers confirms that it occupies a different type of niche, 
associated with its more marked preference for the understory, dif- 
ferent foraging technique, and larger size and longer bill (all but one 
of my S. nouhuysi specimens weigh more than all specimens of all 
other Sericornis species I took). 


VOICE. ‘The Fore pointed out to me a song said to come from this 
species: a thin, slightly sibilant, rambling warble of only modest length, 
dropping in pitch towards the end. The call notes are a dry ‘ chip”, 
a spitted note unlike that of S. perspicillatus, and a rasped scolding 
note.

Sericornis beccarti subsp. 
Beccari’s Sericornis 
or 
Sericornis virgatus subsp. 
Perplexing Sericornis 


These two species include a confusing group of populations among 
which the species lines are not fully clear. As discussed elsewhere 
(Diamond, 1969), S. virgatus is apparently a hill forest species living 
at 2,000-4,500 ft on the Vogelkop, the northern slopes of the Central 
Range west of long. 143°F, and several of the “north mountain 
islands.” S. beccarit is apparently confined to the flat lowlands of 
southern New Guinea and the Aru Islands near sea level, and to the 
Cape York Peninsula of Australia. At Lake Kutubu (2,450 ft) Schodde 
and Hitchcock (1968, p. 45) took one specimen of this complex, the 
first record from the southern hill slopes of the Central Range. ‘They 
tentatively related it to the population tdenburgi of northwestern 
New Guinea, based on the published description of that race, but 
they lacked comparative material, without which racial assignment of 
Sericornis forms is practically impossible, and they recognized that the 
affiliation with tdenburgi was improbable on geographical grounds. 
Further speculation as to the race and species represented must await 
taxonomic comparison of the specimen.

STOMACH CONTENTS. Insects. 

TAXONOMY. Acanthiza murina is confusingly similar super- 
ficially to the smaller species of Sericornis. It has a distinct, dark, sub- 
terminal band on the tail, a whitish iris, an absolutely even, dingy, 
ventral coloration (no orange on the throat or cheeks), and a dull, 
even, olive color above. Differences between it and Sericornis papuensis 
are summarized under S. papuensis. It may be recognized in the field 
by the very short tail and the whitish underparts. 

DISCUSSION. Of the small warblers, Acanthiza murina has the 
highest altitudinal range, being confined to moss forest above 8,000 ft, 
mainly above 10,000 ft. Its altitudinal range is shared with Sericornis 
papuensis and S. nouhuysi, from which it differs ecologically in that 
it forages from the treetops down to 15 ft above the ground, never 
lower. The ecologically equivalent warbler at lower elevations is 


224 


SPECIES ACCOUNTS 


Gerygone cinerea. Acanthiza murina is usually seen in loose flocks of 
3-10 individuals spread out over several adjacent trees, eleaning (not 
sallying or hovering) on leaves and small twigs, rarely on larger 
branches. It moves by short hops of several inches up to a foot, and 
the flocks feed systematically for several minutes in one tree before 
moving on to the next tree. 

VOICE. ‘The song consists of four similar pairs of notes, the first 
member of each pair being on a higher pitch than the second. Members 
of flocks continually give faint, sweet, almost tinkling contact calls, by 
which the flock is easily located. 


Songs of the Genus Gerygone 


There are five species of Gerygone whose songs I have had the op- 
portunity to hear at various localities: G. ruficollis in the Eastern 
Highlands and a recording from the Baliem Valley of western New 
Guinea, G. chrysogaster in the Eastern Highlands and North Coastal 
Range, G. magnirostris in the North Coastal Range and on Karkar, 
G. olivacea in southeastern New Guinea and in Queensland (Aus- 
tralia), and G. igata in New Zealand. The songs of all five are high- 
pitched, have a thin and somewhat plaintive quality, are delivered 
fairly fast, and are based on machine-gun patterns of about a half 
dozen notes which are repeated two to nine times in immediate suc- 
cession. Figure 23 illustrates the songs of G. ruficollis and G. chryso- 
gaster in the Eastern Highlands, and of G. olivacea, G. magnirostris, 
and G. igata for comparison. I did not hear songs from G. cinerea, G. 
chloronota, or G. palpebrosa.

BREEDING. All three Mt. Karimui specimens had the testes much

DISCUSSION. ‘This tiny, inconspicuous warbler occupies between 
about 5,400 and 8,500 ft in forest the niche that Acanthiza murina 
does at higher altitudes. Flocks of 2-10 individuals spread out over 
several trees, forage from the treetops down to 15 ft above the eround, 
gleaning leaves, twigs, and small branches. Unlike Acanthiza murina, 
Gerygone cinerea occasionally hovers and makes short sallies, its be- 
havior is more nervous, and its foraging less systematic. At the forest 
edge it also gleans in the understory. ‘The transition altitude between

STOMACH CONTENTS. Insects. 

TAXONOMY. ‘The black bill and the brownish-olive upperparts 
place this specimen with nominate chrysogaster (notata and dohertyi 
have olive upperparts and a horn-colored bill). 

BREEDING. ‘The greatly enlarged testes of the specimen and the 
frequent songs indicate that G. chrysogaster was in breeding condition 
at Soliabeda. 

DISCUSSION. At Soliabeda this low-altitude warbler was common, 
accounting for 69% of bird individuals. One song was heard at 2,150 ft 
between Soliabeda and Karimui, but the species was absent at Karimui, 
and there are no other Eastern Highlands records. Single individuals 
or small groups were seen moving rapidly in forest and in second- 
growth trees, generally in the middlestory but sometimes descending 
to within a few feet of the ground. G. palpebrosa was also present at 
Soliabeda but apparently did not descend into the lower story. 

VOICE. A typical weak Gerygone song consisting of a repeated 
five-note pattern introduced by three or four extra notes (Fig. 23, p. 
226). If one discharges a gun and G. chrysogaster is in the vicinity, it 
immediately sharts up its song. A continuous dry chirping may also be 
heard occasionally. 


Gerygone chloronota subsp. 
Gray-headed Gerygone Warbler 


I have no specimens but do have sight records of birds observed at 
such close quarters as to preclude the possibility of misidentification. 
Between 6 and 9 July 1965 I saw one individual daily at Bomai, 
flitting 10-60 ft above the ground in a tree at the edge of a ravine. In 
August 1964, ‘lerborgh studied some groups of 2-6 in a small flowering 
tree at Karimui, standing at the edge of a garden several hundred yards 
from forest. ‘hey were the only bird species exploiting this tree and 
kept up a nearly continuous flow of soft vocalizations as they probed 
between the petals. ‘The species evidently prefers trees in open habitats. 
In New Guinea G. chloronota is a rare species, known from few and 
scattered localities.

TAXONOMY. ‘These belong to the southeastern New Guinea 
race. The race tarara from coastal parts of the southern New Guinea 
bulge west of the Fly River differs in the male most obviously in the 
brownish tinge of the black parts of the throat and head; wahnesi 
of northern and northeastern New Guinea differs in the black crown 
(olive in the Karimui specimens); and nominate palpebrosa of the 
Vogelkop differs in the brighter and more yellow-green back. The 
dorsal coloration of museum specimens foxes with age. 

BREEDING. ‘The testes were greatly enlarged in both specimens. 

DISCUSSION. In the Karimui region G. palpebrosa was present 
from 4,200 ft down to at least 1,350 ft. ‘There seem to be no other 
Eastern Highlands records yet, but it will doubtless turn up at other 
hill forest stations. Pairs or small groups flit rapidly in trees of the 
forest and at the forest edge. I never netted this warbler or saw it less 
than 10 ft from the ground.

the back, and dingy dark olive on the head. ‘The tail feathers have the 
characteristic white spots. 

DISCUSSION. With the possible exception of the honeyeater 
Melidectes torquatus, no other midmontane species has profited so 
spectacularly from native agriculture as G. ruficollis. In primary forest 
it is hard to see but easy to locate by song. ‘These songs indicate that 
it was not uncommon in primary forest on Mt. Karimui between 4,500 
and 6,500 ft, and present but uncommon around 8,000 ft on Mt. 
Michael. However, in trees in open habitats cleared by man in the 
Eastern Highlands, and especially in casuarina groves, this nervous 
warbler is often the most abundant bird, occurring in flocks of up to 
20 and even up to 50 birds. It has similarly colonized the open habitats, 
again casuarina groves in particular (Rand, 1942b, p. 476), in the 
Baliem Valley of western New Guinea. In southeastern New Guinea, 
but apparently not elsewhere, it is common in treeferns in alpine 
grassland. 

VOICE. An unmistakable, high pitched, plaintive, fairly rapid (ca. 
six notes per second), and lengthy song. ‘The first 10 to 30 notes 
gradually descend in pitch, eventually level out at a constant pitch, 
and thereafter every fifth note is lower in pitch by an interval of a 
third or a fourth, forming a five-note pattern which is the origin of 
the Fore nace ‘“‘e-ne-me-si-lo”. The “enemesilo” phrase is repeated 
three to nine times to conclude the song (Fig. 23, p. 226). Sometimes all 
the “enemesilo” phrases are omitted, and the song terminates after the 
initial 10 to 30 notes. Voice recordings from the Baliem Valley which 
I have heard are essentially the same. 

Ripley (1964, p. 59) gives the following description of the song of the 
warbler Phylloscopus trivirgatus in the Baliem Valley: ““Uhese warblers 
have a long, drawn-out series of single whistling notes on a descending 
scale, rather pretty but mournful. ‘The notes remind me of the song of a 
North American White-throated Sparrow, Zonotrichia.” ‘This is an 
accurate description of the Gerygone ruficollis song. ‘The song of 
Phylloscopus trivirgatus is also high but completely different in form 
and pattern, and the attribution of the Gerygone song to Phylloscopus 
is surely an error, one, however, which could arise easily, as both are 
small and nervous tree warblers. 


Niche Differences in the Genus Crateroscelis 


This genus of three species, which was formerly placed with the 
babblers but is now assigned to the warblers, illustrates the course of 
altitudinal sequences of more than two congeners in New Guinea. All 
three species are quite similar in appearance and habits. In a few areas 
all three are present and replace each other subsequentially: C. mwrina 
at low altitudes, C. nigrorufa at middle altitudes, C. robusta at higher 
altitudes. In many or most areas, however, C. nigrorufa is absent, and 


229 


SPECIES ACCOUNTS 


there is a sharp boundary between the altitudinal ranges of C. murina 
and C. robusta. This “squeezing-out” of the middle species seems to be 
a common result of multiple altitudinal replacement in other genera 


as well (Pe 94),

WING. 10 ¢: 59-63 (61 +1). 10 9: 55-61 (57 + 2). 

TAXONOMY. The races monacha, pallida, fumosa, and capitalis 
are paler, especially on the underparts, while fumosa and capitalis are 
also smaller. The Eastern Highland series belongs to the dark-bodied, 
dark-crowned, widespread New Guinea race C. m. murina. Birds from 
the Karimui area average darker than those from Okasa, as is often 
the case at Karimui. 

BREEDING. Gonad condition was as follows: Okasa, testes small 
in all males examined; Karimui, testes enlarged in most but not all 
males, one nestling brought in on 16 July; Mt. Karimui, testes small 
in three males, slightly enlarged in a fourth, ovaries small in all 
females. ‘his suggests that breeding of this lowerstory species is in the 
dry season at Karimui but not at Okasa or on Mt. Karimui. 

DISCUSSION. C. murina is the commonest bird in the understory 
of hill forest. In the flat coastal plains and near sea level it is quite 
sparsely distributed, sometimes even absent. At Soliabeda (1,500-2,000 
ft) it still accounted for only 1.2% of all birds. This figure had risen 
to 4.9% at Karimui (3,650 ft), and thereafter C. murina became 
progressively more abundant as we worked our way up Mt. Karimui, 
accounting for 9.2% of all birds in Zone 3, until it abruptly disap- 
peared between 5,390 and 5,400 ft, where it was replaced by C. robusta. 
One of our campsites was near this transition altitude, and I had 
frequent opportunity to check the strictness of the transition by noting 
that C. murina songs always came from below this altitude, C. robusta 
from above. 

C. murina remains within the forest and is seen as solitary indi- 
viduals or as small parties of two or three birds, on the ground, on 
fallen logs, in low bushes, and in thickets. I have not seen it more 
than 5 ft above the ground. Singers are dificult to locate, and the 
species is far more often heard than seen. 

VOICE. A beautiful whistled song characterized by the distinct- 
ness of its notes, the simplicity of its patterns, and the very clear 
quality sug egestive of a flute in the higher registers, and, like a flute, 


230 


SPECIES ACCOUNTS 


with a “breathy” quality when heard close. Patterns consist of 2-10 
notes, most commonly of either three or four notes. Frequently each 
note has the same time value; sometimes a dotted rhythm is used, the 
first note may be detached, or a subsequent note may be held longer 
than the others. An average length for the song is 1-114 sec, but 3 sec 
is not unusual. The pitch range of the whole song may be encompassed 
within a fourth or major third, and intervals between successive notes 
are close to half-tones, whole tones, or thirds. A given individual uses 
at least eight to 10 different patterns. Each pattern is repeated three to 
six, sometimes up to 16, times, with pauses between repetitions, before 
the singer goes on to the next pattern. Figure 24 illustrates many of the 
C. murina patterns I have heard in the Eastern Highlands (patterns | 
through 10 were used successively by one singer, I] through 18 by 
another). ‘Phe call is a dry “chip” or a squawk.

southeastern New Guinea rather than with blissi of the Snow Moun-

pared to my specimen, southeastern New Guinea birds are slightly 
browner, less black, dorsally, but this may be due to foxing, since 
they were collected in 1903-1906.

TAXONOMY. As already noted by Gyldenstolpe (1955, p. 84) and 
by Mayr and Gilliard (1954, p. 345), there is much individual variation 
in the color of the underparts (brown or gray). ‘The present series sug- 
gests that this is to some extent, though probably not entirely, a 
matter of age, the brownest underparts being in the younger birds. ‘The 
color of the throat also varies, and is whitest in specimens with the 
least brown underparts. Gyldenstolpe’s series also suggests a correlation 
with age: all nine of his gray males have longer wings than four of his 
five brown males, and four of his six gray females are larger than three 
of his four brown ones. However, one of his brown males had enlarged 
testes. Eye color also varies individually, as noted previously by Mayr 
and Rand (1937, p. 107). In adult males the iris is orange, straw- 
colored, or light straw-orange; brown or orange-brown in adult females; 
and dull brown or gray-brown in immatures of both sexes. 

The race sanford: differs in its much buffer underparts, deficiens in 
the absence of the gray breast-band. 


BREEDING. ‘Testes were enlarged in all three adult males from 
Mt. Karimui and in one of the two adult males from Awande. 


DISCUSSION. C. robusta is nearly as ubiquitous and common in 
forest at higher altitudes as C. murina is at lower altitudes. It ap- 
peared abruptly on Mt. Karimui at its maximum abundance at 5,400 
ft, and accounted for about 5% of the local avifauna in the zones from 
5,400 to 6,250 ft, about 3°% in the zones of stunted moss forest from 
6,250 to 7,280 ft, about 1% up to 7,610 ft, and was not encountered 
on the top 500 ft of the mountain. On Mt. Michael it was present 
from the base of the forest (7,000 ft), commonest around 8,000 ft where 
the forest was still tall, and still present up through the progressively

SPECIES ACCOUNTS 


more stunted moss forest until at least 10,200 ft. Its behavior is similar 
to that of C. murina, i.e., it remains in the lowest story of the forest 
or searches in leaf litter on the ground, singly or in pairs, and is much 
more often seen than heard. 

VOICE. A whistled song similar to that of C. murina but with a 
less flute-like, thinner, and more tinkling quality, more irregular 
rhythm, more hurried delivery, and consisting on the average of more 
notes (five or six is typical). As does C. murina, C. robusta alternates 
patterns, a few of which are given in Figure 24 (p. 231). Its call is a 
short, dry, very buzzy note similar to that of Sericornis nouhuysi. 


SYLVIINAE: WARBLERS 
Acrocephalus arundinaceus subsp. 
Great Reed Warbler 


DISCUSSION. According to Bell (1968) this warbler is very numer- 
ous in dense “pit-pit” (tall cane grass) and tall elephant grass in the 
Baiyer River Valley of the northern watershed (3,600 ft) and on the 
Sepik-Wahgi Divide at 6,600 ft. One specimen has been collected near 
Mt. Hagen, and there is a sight record from Pureni (N.G.B.S. News- 
letter, No. 28, p. 3, Feb. 1968). Its distribution throughout New Guinea 
is spotty. 

VOICE. A lengthy, rich song composed of single and paired notes 
of varied qualities, each repeated 3-5 times before going on to the 
next note. The form suggests New World mimic thrushes (Mimidae) 
or the European Song Thrush (Turdus philomelos).

TAXONOMY. ‘This species is subject to both altitudinal and local 
geographical variation. ‘The first high-altitude form discovered was 
alpinus from the alpine grasslands of southeastern New Guinea, which 
differed from macrurus of the southeastern midmontane and_ low- 
altitude grasslands in its longer wing, grayer underparts, and darker 
back. The midmontane and alpine forms of the Snow Mountains dif-

SPECIES ACCOUNTS 


fered in the same way and were also assigned to macrurus and alpinus. 
Mayr and Gilliard (1951, p. 9) then described two analogous forms 
from the Wahgi region of the Eastern Highlands: wahgiensis of the 
midmontane grasslands, fairly close to alpinus in color but with a 
longer tail and shorter wing; and montanus of the alpine grasslands, 
ah the short alpinus tail but darker color. The situation subse- 
quently became more complicated when Sims (1956, p. 415) analysed 
Shaw-Mayer’s material from Mt. Giluwe and showed that the color 
patterns there were “upside-down,” i.e., the alpine form was the paler 
one, although it had the shorter tail as in the Wahgi Valley. More 
recently Gilliard and LeCroy (1961, p. 48) assigned Telefolmin mid- 
montane birds to neither macrurus nor wahgiensis but to alpinus on 
the basis of the longer wing, and Schodde and Hitchcock assigned one 
specimen each from Lake Kutubu (2,450 ft) and Mendi (6,900 ft), 
between Telefolmin and the Wahgi Valley, to macrurus. Wing and 
tail measurements and color may vary independently, and future 
collectors should state all three; Mayr and Gilliard gave no wing 
measurements in their descriptions of wahgiensis and montanus, and 
Gilliard and LeCroy gave no tail measurements for the ‘Telefolmin 
series. 

In dorsal color the Awande and Karimui specimens are close to 
wahgiensis from Mt. Hagen (Tomba) and Mt. Kubor, and differ from 
each other only in the darker crown of Karimui birds. The race 
macrurus of southeastern New Guinea is shorter winged, shorter tailed, 
and less dark above. M. t. muscalis of the Fly River differs in its 
streaked crown, shorter wing, and paler, less brown dorsal coloration. 
My measurements of Hagen and Kubor wahgiensis give: Hagen, 3 9, 
wing 64, 66, 68, tail 97, 95, 98; Kubor, 1 9, wing 63, tail 104. While 
the number of specimens is small, there seems to be local variation in 
measurements even in midmontane wahgiensis of the Eastern High- 
lands. Combining my measurements of females with Gyldenstolpe's 
measurements (1955, p. 90) of Nondugl females, one finds wing length 
decreasing in the order Karimui > Hagen = Awande > Kubor = 
Nondugl; tail length decreases in the order Awande = Kubor > 
Hagen = Karimui > > Nondugl. This local variability, plus the 
upside-down and checkerboard racial distributions mentioned in the 
previous paragraph, makes reassessment of the New Guinea races of 
this species desirable. 

BREEDING. One of the Karimui females had enlarged ovaries. 
This, plus the capture of the juveniles, suggests some breeding in the 
dry season, but perhaps not the uniformly synchronized breeding seen 
in Malurus alboscapulatus. 

DISCUSSION.  AIl observers have found this warbler common and 
widespread in the midmontane grassland of the Eastern Highlands. 
Its habitat is grass several feet high, from which it is harder to flush 
than Malurus alboscapulatus. Bell (1968) found in the Baiyer Valley

that Acrocephalus arundinaceus has colonized tall, ungrazed grass, 
whereas Megalurus timoriensis is in grass grazed down by cattle to 
balls about three feet high. Gilliard, Shaw-Mayer, and Bulmer also 
found Megalurus timoriensis in alpine grassland. ‘This warbler is thus 
of interest in having a discontinuous altitudinal range in alpine grass- 
land (> 11,000 ft), man-made midmontane grassland (ca. 3,000-7,500 
ft), and grassland of the lowlands. 

VOICE. The call is a single dry note “tsip’” or “tsick’’ or “CRUD; 
which often sounds disyllabic. ‘here is also a repeated scolding note

BREEDING. Neither specimen had the gonads enlarged, suggest- 
ing that this species may be exceptional among grassland birds in not 
breeding during the dry season. 

DISCUSSION. ‘The distribution of Cisticola exilis in the Eastern 
Highlands is local. Besides collecting it in the grasslands at Okasa in 
June 1965 and observing it there in August 1946, I was told that it 
occurred at Awande, but I found it nowhere else, and it was certainly 
absent at Karimui. Neither Gilliard nor Gyldenstolpe met it in the 
Wahgi Valley. Bell (1968, and pers. comm.) found it near Mt. Hagen 
“quite numerous but strictly localized to areas of short blady grass”; 
Shaw-Mayer collected one at 7,300 ft on Mt. Giluwe; and Bulmer 
reports it as common in the Baiyer Valley around 4,000 ft and in the 
Kaironk Valley of the Schrader Range up to 5,000 ft. 

VOICE. ‘The very distinctive song consists of two very faint notes 
“hoo-hoo” 14-1 sec apart, followed by a disyllabic musical note of bell- 
like absolute clarity (Fig. 25). So different are the qualities of the two 
halves of the song that they give the impression of coming from two 
different species. The song is given from the top of a bush, or even of 
a tree, if any is in the vicinity. The dry, drawn-out call note suggest a

TAXONOMY. ‘These specimens were prepared as skeletons or

and Gilliard (1954, p. 347) and Gyldenstolpe (1955, p. 96) assigned 
specimens from the Wahgi region to giulanettit. 


DISCUSSION.  P. trivirgatus is one of the half dozen commonest 
forest birds in its altitudinal range (ca. 4,300-7,000 ft, in the forest 
interior, forest edge, and trees of second-growth and gardens). On Mt. 
Karimui it first appeared around 4,300 ft, was commonest between 
5,100 and 5,900 ft where it accounted for 5-10% of all birds, and dis- 
appeared around 6,100 ft. On some outlying mountain ranges of New 
Guinea (e.g., the North Coastal Range and Vogelkop) it is largely con- 
fined to altitudes below 5,000 ft. While it sometimes descends to within 
10 ft of the ground, it usually remains in the treetops where it is more 
easily identified by voice than by sight. As it gleans, it moves by short 
hops of a few inches to a foot and occasional flights of several feet. 

VOICE. A high, brief, patternless warble, often concluding with a 
very high upslur apparently continuing to go up out of the human 
auditory range.

BREEDING. All specimens had small gonads. 


DISCUSSION. ‘The genus Pellops is endemic to New Guinea, has 
no close relatives, and consists of two monotypic species. P. blainvillit 
is so exceedingly similar morphologically to its higher-altitude sibling 
species P. montanus that it was not until 1921 that montanus was de- 
scribed even as a subspecies of P. blainvillit. ‘The careful comparisons 
of Stresemann (1923, p. 92) and Gilliard and LeCroy (1961, p. 52) re- 
vealed only two diagnostic characters. First, P. montanus has a longer 
wing and tail than P. blainvillii; this suffices to separate most but not 
all specimens, because there is some overlap and also because P. mon- 
tanus decreases in size with decreasing altitude (Bergmann effect) and 
approaches the size of the low-altitude form P. blainvillii. ‘The second 
diagnostic character is the larger white patches on the back and on 
the cheek of P. montanus; this is also a good but not perfect distin- 
euishing character, since there is some overlap with P. blainvillit. Both 
species behave similarly and inhabit the same kinds of habitats; I 
have been unable to detect ecological differences except in altitudinal 
range. In the field, however, the two species are easily distinguishable 
by their dissimilar and frequently given calls. 

The altitudinal ranges of P. blainvillit and P. montanus are mutually 
exclusive. I found P. blainvillii only between 1,500 and 2,000 ft at my 
lowest-altitude locality, Soliabeda. My lowest record of P. montanus 
was at 2,680 ft between Yudo and Soliabeda, leaving a gap of 680 ft in 
which no Peltops was found. ‘There appeared to me to be a similar 
gap in the North Coastal Range distributions, and I cannot find a 
published record of P. montanus under 2,500 ft, nor of P. blainvilli 
above 2,000 ft except for a specimen taken by Schodde and Hitchcock 
at Lake Kutubu (2,450 ft). Hence the apparent gap could be real. 

At Soliabeda P. blainvillit was uncommon. Groups of up to four 
perched in the crowns of tall trees overlooking small clearings in the 
forest. From these perches they sallied after insects often at considerable 
distances from the crown, sometimes to within a few feet of the 
ground. The territory must be large, since successive treetop perches 
may be several hundred feet apart. 


VOICE. Unique among New Guinea birds in that the notes are 
very sharply sucked in. ‘The rhythm is usually iambic, e.g., three rapid 
pairs of notes, all on the same pitch, the first member of each pair 
short and unaccented (Fig. 26). At each pair of notes the head is thrown 
violently up and down. Sometimes three or four sucked-in notes in 
rapid succession on the same pitch are given in uniform rhythm. The 
quality is totally unmusical, i.e., clicked or snapped. Once I heard a 
faint call of three rapid unmusical notes on successively lower pitches, 
like a weak, abbreviated fragment of the usual Peltops montanus call.

Michael). It was present at most of my stations in this altitudinal range 
but was definitely absent at Okapa (6,600 ft), Awande (6,000 ft), and 
Miarosa (5,800 ft), both in my experience and in the much more ex- 
tensive experience of my Fore assistants. It was not found in the 
Wahgi Valley by Gilliard or Gyldenstolpe. Bulmer found it breeding 
in Kyaka territory in 1955, when he collected five specimens and re- 
corded one nest between 4,300 and 5,300 ft, but he did not encounter 
it in the four months he spent there in 1959. 


238 


SPECIES ACCOUNTS 


The habitat of this species may be easily summed up as tall forest 
trees at the edge of open spaces. From conspicuous perches which are 
rarely less than 40 ft above the ground, P. montanus sallies into the 
open space to catch insects and returns to its perch or to a neighboring 
tree, sitting stationary between sallies. On the Sena River the trees 
chosen were on the river bank, and the open space exploited was that 
over the river. In the virgin forest on Mt. Karimui the perches were 
initially in tall trees emerging above the canopy or on a ridge. When 
we had cleared small campsites in the forest, trees at the edge of these 
were also used. At Karimui, where many gardens and roads had been 
cleared, trees at the border between these clearings and the forest fur- 
nished perches. It is surprising that this species, which concentrates 
at natural open spaces in the forest, is not far more abundant and 
widely distributed in settled areas of the Eastern Highlands. Like P. 
blainvillti, P. montanus is a social species, seen usually in groups of 
2-5, though sometimes singly. Once I saw a P. montanus attack a 
perched hawk Aviceda subcristata and force it to take flight. 


VOICE. A very rapid series of a half dozen to a dozen notes 
lasting in all less than | sec, and descending slightly in pitch (Fig. 26, 
p. 238). The volume is soft, and the quality quite similar to that of 
the sound produced by running one’s finger along the teeth of a comb. 
Infrequently one hears a hoarse upslurred “‘wheep.” 


Songs and Niche Differences in the Genus Rhipidura 


It is interesting to attempt to deduce species relationships within 
this genus from songs, since the 12 species I have encountered fall into 
three distinct groups on this basis. R. leucothorax and R. threnothorax 
resemble each other in their loud, explosive songs very unlike those of 
the other 10 species. ‘The harsh song of R. lewcophrys places it by itself 
in another group. ‘The songs of the remaining nine species (R. atra, R. 
brachyrhyncha, R. albolimbata, R. hyperythra, R. rufiventris, R. rufi- 
dorsa, plus R. fuliginosa which I heard in New Zealand, Australia, 
and Espiritu Santo, R. dahli of New Britain, and R. nebulosa of 
Samoa) are all weak and high-pitched, and consist of either or both 
of two kinds of notes: clear whistled notes and jumbled twitters. R. 
albolimbata and R. hyperythra, in whose songs clear whistled notes 
predominate, are particularly close to each other, and R. brachyrhyn- 
cha and R. atra are close to each other in their squeaky, tinkling, jum- 
bled songs. ‘The songs of R. fuliginosa and R. dahli are similar to those 
of R. brachyrhyncha and R. atra. This vocal “classification” is in rea- 
sonable accord with a grouping based solely on morphology. 

Niche differences among the nine species of Rhipidura in the East- 
ern Highlands may be summarized in oversimplified form as follows. 
R. ieucophrys is confined to open country such as gardens and villages, 
whereas the other species all live in the forest or dense second-growth. 


239 


SPECIES ACCOUNTS 


‘Three species live mainly in the forest understory and have mutually 
exclusive altitudinal ranges: R. threnothorax at low altitudes (to ca. 
3,000 ft), R. atra at middle altitudes (3,000 to ca. 7,000 ft), R. bra- 
chyrhyncha at high altitudes (above ca. 7,000 ft). ‘The latter two ven- 
ture into the middlestory, which R. threnothorax rarely does. ‘The 
altitudinal range and the lowerstory preference of R. leucothorax are 
similar to those of its close relative R. threnothorax, but R. leuco- 
thorax lives in thickets at the forest edge and in dense second-growth, 
R. threnothorax in the forest interior. R. hyperythra and R. albolim- 
bata are forest species that forage from the crowns to the understory, 
most often in the middlestory or crown, and have mutually exclusive 
altitudinal ranges, R. albolimbata living at higher elevations (above 
4,500 ft) than R. hyperythra (below 4,500 ft). R. rufiventris lives in 
more open parts of the forest and is commonest at the forest edge or 
adjacent to open spaces (not in the thickets utililized by R. leuco- 
thorax), occurs from sea level to ca. 5,000 ft, forages from the crowns 
to the understory, and is larger than R. hyperythra or R. albolimbata. 
R. rufidorsa is a forest species of the lower- and middlestories, confined 
in the Eastern Highlands to elevations below 2,000 ft, where R. hy- 
perythra is uncommon.

BREEDING. One female at Karimui was captured on a nest from

enlarged in half of the Karimui males, small in the others; and small 
in the sole Soliabeda male. Evidently many, but not all, individuals of 
this understory species were breeding in the dry season. 

DISCUSSION. R. threnothorax has not yet been recorded in the 
Eastern Highlands outside the Karimui area, where it is somewhat 
above its usual ceiling. It is shy, solitary, and infrequently seen but 
not uncommon. Of the forest fantails this is the most sharply re- 
stricted to the understory, the few that I saw being at most 3 ft above 
the ground and sometimes on the ground. It favors those parts of the 
forest or forest edge that have particularly dense undergrowth.

BREEDING. ‘Testes were small in one Soliabeda male; enlarged in 
the second Soliabeda male, which had been consistently singing from 
the same thicket for several days; and enlarged in the Karimui male. 


DISCUSSION. R. leucothorax is not a forest bird but remains 
inside the densest and most tangled thickets and in second-growth and 
at the forest edge, not necessarily in the shade of taller trees. While it 
was a noisy singer and moved about within these thickets, it stayed 
largely concealed and was difficult to observe. ‘The unbalanced sex ratio 
in my series (3 ¢, 0 9) and in the American Museum of Natural 
History’s collection (21 4, 6 ¢?) is probably because females of this 
skulking bird are much more likely to escape detection than singing 
males. It adopts an exaggerated fantail posture, with the tail fully 
spread. 

‘This fantail was uncommon and local in the Karimui area, where 
it was considerably above its normal altitudinal range. In the Karimui 
Basin itself my only records were of a song heard in a thicket near 
Iogoramalu (3,700 ft) and of the specimen brought in at Karimui by 
a native. The species was also taken by Schodde and Hitchcock at Lake 
Kutubu (2,450 ft) and has been observed in the Baiyer Valley (3,500 
tt; IN.G_ Bs. Newsletter, No. 54, p. 2, June 1970). 

VOICE. ‘The song consists of a short series of rapid, spitted or 
staccato, imitially faint notes which accelerate and rise in pitch, to 
terminate in a loud, explosive, slurred note suggestive of a Pachy- 
cephala (Fig. 27).

TAXONOMY. The rufous of the back in Rhipidura rufidorsa 
becomes gradually paler as one proceeds counter-clockwise around the 
periphery of New Guinea: kumust on the north coast of southeastern 
New Guinea is the brightest, kwbuna on the south coast of southeastern 
New Guinea is the dullest, and nominate rufidorsa of the rest of New 
Guinea is intermediate. R. r. Rubuna is also the palest form. The 
Soliabeda male is somewhat brighter than kubuna, duller and darker 
than nominate rufidorsa from the Fly River, and considerably darker 
than rufidorsa from the Weyland Mountains and south slope of the 
Snow Mountains. It is closest to Fly River rufidorsa, but a definite 
racial assignment requires more material. 

BREEDING. ‘The testes were enlarged. 

DISCUSSION. ‘The sole specimen was netted, and no other was 
seen or heard. 

VOICE. ‘Three or four high, whistled notes, suggestive of Cratero- 
scelis murina in quality but slightly upslurred. The notes either move 
progressively down the scale, or else the last note returns to the pitch 
or the first (Kio. 27, p, 242).

TAXONOMY. Rhipidura brachyrhyncha_ exists in two color 
phases, as discussed by Mayr and Rand (1937, p. 164): a darker phase 
with much black in the tail (Type I of Mayr and Rand) and a paler 
phase with no black in the tail (Type Ht of Mayr and Rand). All of 
my specimens are ‘Type I except the Mt. Karimui Zone 7 male, which 
is Type II. The five specimens which Gyldenstolpe (1955, p. 97) 
collected in the Wahgi Mountains and the three which Biirgers took 
in the Schrader Range (Stresemann, 1923, p. 8) were all Type I. Mayr 
and Gilliard (1954) do not state the proportions in Gilliard’s speci- 
mens, but four of these are present in the American Museum of 
Natural History, and all are Type I. In the Snow Mountains the Third 
Archbold Expedition (Rand, 1942b, p. 478) obtained 15 of Type I and 
4 of Type H, Ripley (1964, p. 60) 3 and 1, and the Lorentz expedition 
(Junge, 1939, p. 29) 2 and 0. In southeastern New Guinea I found 
‘Type I twice as common as ‘Type II. However, Mayr and Rand (1937, 
p. 167) state that the proportions are nearly equal in the Vogelkop 
and the Huon Peninsula. Evidently there is some geographic variation 


243 


SPECIES ACCOUNTS 


in the proportions, with Type l predominant in the central body of 
New Guinea. The related fantail R. fuliginosa of New Zealand also 
has two color phases whose relative abundances vary geographically. 


BREEDING. Gonads were small. 


DISCUSSION. ‘Three species of Rhipidura—R. brachyrhyncha, R. 
atra, and R. albolimbata—occur in the forest interior at higher eleva- 
tions and are usually not in second growth. Niche differences involve 
altitudinal distribution, and vertical distribution within the forest: 

As regards altitudinal distribution, all three species may coexist in 
an overlap zone around 7,000 ft, where R. atra and R. brachyrhyncha 
overlap by about 500 feet, but for the most part R. brachyrhyncha 
lives from this altitude up to about 11,000 ft, R. atra from this altitude 
down to 3,000 or 4,000 ft. These two species are much more closely 
related to each other than to other New Guinea Rhipidura species, 
as indicated by their songs, their lowerstory preferences, and the similar 
plumage of R. atra females and R. brachyrhyncha Type 1. They may 
have originated as an altitudinal pair and eventually developed 
enough differences in foraging behavior (see Mayr and Rand, 1937, 
p. 161) to permit modest altitudinal overlap. R. albolimbata shares 
the whole altitudinal range of R. brachyrhyncha and much of the 
range of R. atra, extending from 11,000 down to 4,500 ft, where it is 
replaced by R. hyperythra. 

As regards vertical distribution within the forest, R. albolimbata 
and R. hyperythra are characteristic of the middlestory (5-60 ft above 
the ground, occasionally lower or higher). R. atra and R. brachy- 
rhyncha are most often seen in the understory (ca. 2-8 ft above the 
ground, sometimes to 20 ft) and favor denser thickets than do R. 
albolimbata and R. hyperythra. The characteristic habitat of R. brachy- 
rhyncha is stunted moss forest, and it has turned up at most Eastern 
Highlands collecting stations in this habitat. ‘Vhus, the lower altitudi- 
nal limit of R. brachyrhyncha and the upper limit of R. atra are 
strongly dependent upon local conditions. In the Okapa area, where 
we ascended to 7,500 ft without reaching moss forest, R. brachyrhyncha 
was absent, and R. atra went up to at least this altitude. On Mt. 
Michael, where moss forest began at 8,700 ft, R. brachyrhyncha 
descended to 8,000 ft, and R. atra ascended at least to 8,100 ft. On 
Mt. Karimui, where moss forest began rather abruptly at 6,500 ft, 
R. brachyrhyncha descended only to this altitude, and R. atra dis- 
appeared at it except for two records at 7,620 tte 


VOICE. ‘The high-pitched song has a tinkling quality when heard 
nearby but sounds squeaky at a distance. It consists of a run-together 
descending cascade of about seven fast notes, introduced by a couple 
of detached, higher-pitched, slower, upslurred notes (Dig.e2 7, ip. 2a2)- 
The call note is slightly upslurred, high-pitched, and squeaky.

TAXONOMY. The two immature males are in a brown plumage 
resembling that of the adult female. The other males are in a fully 
adult black plumage except for a few brown feathers on one. 


BREEDING. The gonads were slightly enlarged in one Mt. Kari- 
mui male and one Awande male and were small in all other specimens. 


DISCUSSION. Rhipidura atra was present at all my forest collect- 
ing stations between about 2,800 and 8,000 ft, with the conspicuous 
exception of Karimui (3,650 ft) and Bomai (3,250 ft). The possibility 
that it was present but overlooked at Karimui and Bomai is negligible, 
because both my Fore assistants and I knew its song, and it is readily 
netted, conspicuous, and common where present. The most surprising 
discovery of my walk from Karimui down to Soliabeda and vice versa 
was the observation of four R. atra at 2,770 ft and of one at 3,230 ft 
in hill forest on the outer side of the Karimui Basin’s mountain wall. 
As we went up from the Karimui Basin onto the slopes of Mt. Karimui, 
R. atra reappeared at 4,090 ft and continued up to 6,500 ft, with two 
records at 7,620 ft. ‘This hill and mountain forest species thus has a 
discontinuous altitudinal range at Karimui (present at 2,770-3,230 ft 
and 4,090-7,620 ft, absent in between), as a result of the intrusion of 
tropical conditions and flora on the basin floor. It is usually solitary 
and has a typical Rhipidura behavior, displaying with fanned tail and 
spinning about 180 degrees on its perch. 

VOICE. ‘There are three kinds of vocalizations: (1) the call note, a 
loud metallic “pink!”; (2) a very faint twittering progressing upscale; 
and (3) a tinkling high-pitched jumble of a song similar to that of 
R. brachyrhyncha, with a sweet and piercing quality. Once I heard 
this song from an individual in brown plumage (a female or immature 
male).

TAXONOMY. The distinguishing racial feature is the extent of 
white on the tips of the outer tail feathers: 15-20 mm in castaneothorax 
of southeastern New Guinea, 6-14 mm in muelleri from the remainder 
of New Guinea. The figures for my series place it with mueller: 
Okasa, 1 ¢ 12 mm, 2? 14 and 14 mm; Bomai, | ? 11 mm; Guwasa, 1 9 
9 mm. The greater extent in the specimens from Okasa, lying farther 
to the east, suggests an approach to castaneothorax. A specimen from 
Lake Kutubu examined by Schodde and Hitchcock also belonged to 
muellert. 

BREEDING. ‘The gonads were enlarged in one Karimui male but 
not in the other specimens. 


DISCUSSION. R. hyperythra is the middlestory forest fantail of 
lower altitudes up to about 4,500 ft and was collected or observed at 
all my stations in this range, above which it is replaced by R. albo- 
limbata. Its maximum abundance is in hill forest near the upper limit 
of its altitudinal range: i.e., it was common at Okasa (3,500-4,250 ft), 
and in Zone | of Mt. Karimui it accounted for 4% of census totals. 
At Bomai and Soliabeda it was quite uncommon. ‘To judge from pub- 
lished records and my own experience, it is rare and often absent in the 
flat floodplains of the lowlands (Sepik Basin, southwestern New Guinea 
floodplain, Fly River). Its habit of tipping forward, nervously flutter- 
ing its wings and fanning its tail, then spinning around 180 degrees to 
repeat the performance, resembles R. albolimbata. 

VOICE. ‘The quality is as in the song of R. albolimbata, the pat- 
tern is drastically abbreviated, as if R. albolimbata were sparing itself 
its usual ad nauseam repetitions: two short and detached, high-pitched, 
faint but clear and tinkling notes, the second following the first by 
less than J sec and a minor third higher in pitch (Fig. 27, p. 242). An 
even fainter twittering similar to that of R. albolimbata, R. rufiventris, 
and R. atra was heard once.

Valley (Mayr and Gilliard, 1954, p. 348; Gyldenstolpe, 1955, p. 99) 
this species increases in size and darkness with increasing altitude. Ot 
the specimens measured in my series from the southern parts of the 
Eastern Highlands, those with the longest wings (“k’, “I”, “m”) are 
the three from the highest altitude. Specimens “k” and “m” are also 
the darkest (on the back and flanks) and heaviest specimens (‘I was 
not weighed or available for color comparison). ‘The large, dark, high- 
altitude birds have been separated as lorentzit. However, this altitudinal 
cline is gradual and has now been found over a stretch of 600 miles 
in the Central Range. As suggested by Gilliard and LeCroy (1961, 
ps 5a; 1968, p. 19), it therefore seems undesirable to recognize altitudi- 
nal subspecies in this case. 

DISCUSSION. R. albolimbata is the high-altitude forest fantail 
of the middlestory, replacing R. hyperythra above about 4,500 ft. On 
Mt. Karimui’s west peak (the one I studied in detail) the lowest sight- 
ing of R. albolimbata was at 4,630 ft, and the highest of R. hyperythra 
was at 4,360 ft. On Mt. Karimui’s east ridge, where moss forest 
descended lower and which we crossed at 4,420 ft en route from 
Soliabeda back to Karimui, it was R. albolimbata which we found at 
this altitude. However, at 4,500 ft on the Sena River and at 4,250 ft 
in the Okasa forest it was R. hyperythra that was present. R. albo- 
limbata extends abundantly upward throughout the stunted moss 
forest to above timberline, where it forages on tree ferns in alpine 
grassland several hundred feet from the forest edge. 

VOICE. ‘The song is a sequence of clear, detached, short, and high 
notes spaced at intervals of about 1% sec, giving the impression of water 
droplets falling at regular intervals. In the commonest pitch arrange- 
ment the first and third notes are on the same pitch, the second note 
a minor third higher, the fourth note a minor third lower. ‘This four- 
note pattern is the origin of the Fore name “‘ni-ni-ke-su’”’ and is repeated 
ad nauseam without pause (Fig. 27a, p. 242). Less often the song con- 
sists of a five- or six-note phrase which has the same quality and high 
pitch but is not repeated (Fig. 27b). One of these latter patterns, con- 
sisting of five notes each one tone lower than the preceding and con- 
cluding with faint twittering, is close to the song of R. rufiventris.

DISCUSSION. Whereas R. hyperythra is virtually confined to the 
forest interior, R. rufiventris may be found in the forest interior but 
more often occurs in natural forest clearings produced by fallen trees, 
and in open parts of the forest, the forest edge, and second-growth, at 
any height from the ground to the treetops. I observed or collected it 
at all my collecting stations below 5,000 ft that included some second- 
growth, but only up to 4,000 ft in primary forest. As one proceeds 
from 4,000 ft downward, R. rufiventris becomes more common, R. 
hy perythra less common. For instance, R. rufiventris reached its maxi- 
mum abundance at my lowest station, Soliabeda, where R. hyperythra 
was quite uncommon. R. rufiventris still occurs regularly in the flat 
floodplains of the lowlands, where R. hyperythra is quite uncommon 
or absent. ‘There are also differences in behavior: larger R. rufiventris 
does not indulge in the pronounced tail-fanning of R. hyperythra and 
R. albolimbata, and is somewhat less nervous. 


VOICE. ‘The song consists of five descending notes in syncopated 
rhythm, the whole song lasting slightly less than 2 sec (Fig. 27, p. 242). 
The pitch is fairly high, and the successive pitch intervals are somewhat 
less than a whole note. ‘The quality is a thin whistle similar to the 
voice of Crateroscelis murina but less substantial and clear, and more 
substantial than the songs of R. hyperythra or R. albolimbata. ‘The 
pattern is similar to that of some R. lewcophrys songs and to a rare 
R. albolimbata song (Fig. 27b), but the very different quality precludes 
confusion. A repeated faint “whik” was once heard as a call note.

BREEDING. ‘The Awande male had enlarged testes. 


DISCUSSION. ‘The Willie Wagtail is one of the principal avian 
beneficiaries of man-made ecological changes in the Eastern Highlands. 
Whereas it is a lowland species elsewhere in New Guinea, in the 
Eastern Highlands it is common and ubiquitous up to 6,500 ft in open 
country offering perches (but not in pure grassland). Strangely, it is 
only from the Eastern Highlands to Telefolmin that R. leucophrys 
has succeeded in colonizing the midmontane grassland. ‘To judge from 
published records, it is absent from the midmontane grassland of the 
Huon Peninsula, southeastern New Guinea, and the Baliem Valley, 
Ilaga Valley, and Wissel Lakes region of western New Guinea. Its 
perches range from the tops of casuarina groves and of trees overlook-

ing roads and gardens to the ground. Perhaps it is the only widespread 
breeding bird in the Eastern Highlands, apart from the more locally 
distributed Anthus novaeseelandiac, which spends a high proportion of 
its time on open bare ground (i.e., roads and closely cut lawns). Much of 
its food is obtained by flycatching in midair. Willie Wagtails fly up to 
and repeatedly attack perched large birds, like Accipiter fasciatus and 
Corvus orru, and continue to chase them when they take off, partly 
in order to pluck feathers to line the nest. ‘They also chase dogs. In 
some areas Willie Wagtails leave during the dry season and return to 
breed during the rains. 

VOICE. Quite unlike the quality of other New Guinea species of 
Rhipidura. There are two kinds of songs, which may involve notes of 
two sharply different qualities: harsh or grating, low-pitched, louder 
notes, somewhat like Monarcha axillaris in quality, and higher-pitched, 
weaker, whistled notes. Each note has a sharp attack, is staccato, and 
is at constant pitch. One of the two songs is a five- or six-note phrase 
in uneven rhythm and with progressively dropping pitch (Fig. 27a, p. 
242); the phrase may immediately be repeated. The other song (Fig. 
27b) consists either of a three-note phrase in dotted rhythm, in the 
harsh quality, and at nearly the same pitch, the phrase being imme- 
diately repeated; or else (Fig. 27c) consists of this same phrase alternat- 
ing with a phrase in the weaker, higher quality and consisting of four 
rapid-fire notes on the same pitch. ‘These songs are occasionally heard 
at night.

TAXONOMY. ‘The nominate race of the Vogelkop, Weyland

tufts. Immatures of both sexes are uniform dull slate gray, lacking the

specimen has a few brown feathers on the back. Adult females have 


the blue-black sheen slightly less pronounced than in adult males but 
are still readily distinguished from immatures. 


BREEDING. ‘The gonads of the whole series were small, usually

very small, except for being slightly enlarged in two of the Mt. Karimui 
males. 


DISCUSSION. Monarcha axillaris is a forest species with an 
altitudinal range from about 3,000 to 6,000 ft. In my study areas it 
reached its maximum abundance in Zone 1 of Mt. Karimui (4,000- 
4,200 ft), where it accounted for 7%, of the local avifauna, and in the 
Okasa forest (3,550-4,250 ft). The contrast between its abundance on 
the lower slopes of Mt. Karimui and its rareness (0.2% of the local 
avifauna) on the flat basin floor at Karimui Patrol Post (3,650 ft) was 
striking and in agreement with the rareness of many other hill forest 
species in the Basin. Stragglers of M. axillaris turn up irregularly and 
in low numbers at 6,000 ft (e.g., Awande), occasionally higher. ‘This 
flycatcher provides an excellent example of the tendency of immature 
birds to be found at the extremes of a species’ altitudinal range: no 
immature was collected or seen in the species’ “heartland” (Zones 1 
and 2) on Mt. Karimui, whereas all birds collected and seen at Karimui 
Patrol Post were the gray immatures, as was one of the two Awande 
specimens. 

Of the New Guinea representatives of genus Monarcha, M. axillaris 
is the closest to the Rhipidura fantails in its habits. It flits in the lower- 
or middlestory up to ca. 20 ft above the ground, holding its body 
horizontal and fanning its tail, sometimes in groups of up to four 
birds. Superficially Monarcha axillaris resembles male Rhipidura atra, 
so that the Fore called the former by the latters mame ( tretme ); 
Distinguishing features are the white pectoral tufts of the former and 
white superciliary spot of the latter (not always obvious); the lower 
mandible, blue-black in the former and orange in the latter; the voice; 
and behavioral differences. 


VOICE. ‘Three or four identical notes in rapid succession on the 
same pitch, all three or four being completed within 14 sec. ‘The

BREEDING. Gonads were large in one Karimui male, somewhat 
enlarged in the other, and small in all other specimens. 

DISCUSSION. This is a solitary species of the middle- and upper- 
stories (20-80 ft above the ground) of hill forest, between ca. 1,800 and 
5,100 ft in my study areas, varying locally from common to absent. 
There is no straggling to higher altitudes, and there seem to be no 
records above 5,100 ft anywhere in New Guinea. Bulmer collected M. 
frater at 4,000-4,500 ft in the Baiyer Valley. M. frater does not descend 
to the understory and was not netted, differing in this respect from 
its congener M. axillaris, much of whose altitudinal range it shares. 

VOICE. The song (Fig. 28, p. 255) is a fairly loud, mellow, cheerful, 
whistled note repeated several times at intervals of about | sec. Each 
note is initially upslurred and then downslurred and may be preceded 
by a much shorter note. The quality is reminiscent of Pitohui dichrous 
or Meliphaga flaviventer. The call is a dry, buzzy “chuck-chuck-chuck.”

BREEDING. In August 1964 one male and one female at Karimui 
were sexed, and both were found to have enlarged gonads. Out of 
seven males and five females sexed in July 1965 at Karimui, Bomai, 
and Soliabeda, two males and one female at Soliabeda had somewhat 
enlarged gonads, and the other specimens had small gonads. This sug- 
gests that the dry weather of July-August 1965 suppressed breeding, 
as also noted for some other species at Karimui (p. 00). 


DISCUSSION. Other localities where this tropical monarch has 
been found in the Eastern Highlands are Lake Kutubu (2,450 ft) and 
Baiyer River (N.G.B:S. Newsletter, No. 54, p. 2; June 1970). It did 
not even get into Zone | of Mt. Karimui, and was commonest at my 
lowest station, Soliabeda, where it accounted for 2°% of the local 
avifauna. It was an active and solitary forest understory species, forag- 
ing up to 30 ft above the ground. 


VOICE. ‘The call is a dry squawk on constant pitch or slightly up- 
slurred; or else a dry rasped scolding difficult to distinguish from that 
of Monarcha telescophthalmus or Toxorhamphus poliopterus.

TAXONOMY. There are clinal west-to-east color variations in 
both males and females as one proceeds from the Aru Islands and the 
Fly River (race aruensis) to the Karimui area to southeastern New 
Guinea and the D’Entrecasteaux Archipelago (race praerepta). In the 
males, D’Entrecasteaux birds differ from the others by being generally 
more yellow and less orange. ‘The crown of males is most orange in 
Aru Islands and Fly River birds, least so in D’Entrecasteaux birds; 
Sohabeda and southeastern New Guinea birds are intermediate, with 
the Soliabeda male closer to Aru Islands-Fly River birds and south- 
eastern New Guinea specimens closer to D’Entrecasteaux birds. In the 
females the breast is more olive on the Fly River than in the D’Entre- 
casteaux Archipelago, with southeastern New Guinea birds inter- 
mediate and variable. Karimui females are somewhat nearer D’Entre- 
casteaux than Fly River females in this respect but are deeper yellow 
below than these or other praerepta or aruensis. Fly River females are 
more olive, darker, and less yellow dorsally than D’Entrecasteaux or 
southeastern New Guinea females, and in this respect the Karimui 
females agree much better with Fly River females, from which they 
differ in being somewhat more yellow. ‘Thus, the three specimens from 
the Karimui area are on the whole closer to the aruensis than to the 
praerepta end of the cline. 


BREEDING. Gonads were not enlarged in the females and only 
slightly enlarged in the male. 


DISCUSSION. At Karimui and Soliabeda this tropical species was 
very uncommon (ca. 0.2% of the local avifauna). My highest record 
was a single sighting at 4,120 ft on Mt. Karimui. Except for a male 
and female seen chirping at each other, the species was solitary. Its 
habitat is the forest and the forest edge, particularly trees with some 
open space around them. It is even more nervous and active than other 
species of Monarcha and works around the tops and outside of the 
crowns of trees, generally at least 30 ft above the ground, so that it was 
never netted. 


VOICE. The song is a loud musical jumble of mellow notes, spitted 
notes, “cheep’s”, and squawks, accompanied by frequent snapping of 
the bill:

TAXONOMY. ‘The taxonomic analysis of this species is of in- 
terest in that my series is geographically intermediate between harteri 
of south-central New Guinea and henkei of southeastern New Guinea, 
and in that my females are close to the former race and my males to 
the latter. In the male henkei is best distinguished from harterti by the 
(on the average) smaller extent of black on the chin, and in this 
respect my males are closest to henkei. In the female henkei often has 
a paler and more rufous back and faint rufous wash on the abdomen, 
while harterti has a darker, browner, nonrufous back and a pure 
white abdomen; my females agree in both respects with harterti. There 
is also a slight size difference, henkei being larger than hartert:. Mayr 
and Rand (1937, p. 154) give as average wing length ¢ 80.9, 9 78.7 
for henkei from southeastern New Guinea, ¢ 78.5, ? 75.4 for harterti 
from the Oriomo River, while Rand (1942a, p. 338) gives 4 79.5, 
@ 77.0 for harterti from the Fly River. The average values for my 
series (¢ 3108) a 77.0) ane mearer henkerim the male, harterti in the 
female, as are the color characteristics. 

BREEDING. Gonads were very small in all specimens except for 
one Karimui male, in which they were slightly enlarged. 


DISCUSSION. I agree with Ripley (1964, p. 61) that separation of 
this monarch and its Australian relatives in a genus Arses is un- 
desirable. 

Monarcha telescophthalmus was seen fairly often at Soliadeda and 
Karimui, where it accounted for about 1% of the local avifauna. It 
was much less common on Mt. Karimui, and the highest record was 
at 4,900 ft on Mt. Karimui and approximately the same altitude below 
Mengino. Its habitat is the forest, edge of the forest, and second- 
growth, where it is usually found 5-40 ft above the ground. A distine- 
tive habit of M. telescophthalmus not shared with its New Guinea 
congeners is one of standing on or coming down the sides of large 
vertical tree trunks, either right-side-up or upside-down. Whet her 
pursuing these nuthatch-like habits or chasing flying insects, it moves 
actively.

found it in the Baiyer Valley. This lowland species of the forest edge 
and second-growth may spread upward to similar habitats elsewhere 
in ecologically disturbed areas of the hill slopes in the Eastern High- 
lands. I follow Schodde and Hitchcock (1968) in treating the species 
as a Myiagra, not as a Monarcha. 

VOICE. ‘The call is a harsh rasp that crescendoes greatly. ‘The song 
is a rapid trill of clear whistled notes, crescendoing somewhat, and

Hollandia on 4 July 1938, by the Third Archbold Expedition, a male 
taken by Gilliard at Aiome at the foot of the Schrader Range in May 
or late April 1964, and records from Karkar (March 1914; June 1969)

DISCUSSION. I found this rare flycatcher only between 6,100 and 
7,170 ft on Mt. Karimui. The few other Eastern Highlands records 
are also mainly from forest at higher elevations (7,000-8,000 ft in the 
Kubor Mountains, Wahgi Mountains, Schrader Range, and Mt. 
Hagen). Songs came from solitary individuals 6-10 ft above the ground 
in the stunted trees of the moss forest. ‘(Their behavior was nervous; 
the tail was flicked from side to side, and the wings were continuously 
fluttered. The white eyelids and white in the undertail are good field

Niche Differences in the Genera Microeca and Tregellasta 


New Guinea has four widespread species of Microeca (M. flavigaster, 
M. flavovirescens, M. griseoceps, and M. papuana) and one species of 
Tregellasia (T. leucops). Tregellasia resembles New Guinea Microeca 
species in the color of the plumage and in the orange legs, has often 
been considered congeneric with Microeca, and the two genera ob- 
viously share a common derivation. Of these five species, all but M. 
flavigaster have been found in the Eastern Highlands. The following 
discussion of their ecological differences is based partly on my field 
observations in the Eastern Highlands and North Coastal Range and 
partly on the basis of published locality records from other parts of 
New Guinea. 

While the other four species are birds of the forest, the habitat of 
M. flavigaster is savanna and open country with scattered trees, from 
the lowlands up to about 2,500 ft, with one record at 4,800 ft (Tele- 
folmin). 

Of the four forest species, M. flavovirescens is in the lowlands and 
lower hill slopes, dropping out at an altitude which varies locally 
between 2,000 and 4,000 ft; M. griseoceps and T. leucops are on the 
middle hill slopes from about 3,000 to 5,000 ft; and M. papuwana is in 
the mountains above 5,000 or 6,000 ft. Examining local variations of 
the limits in more detail, one finds that the range of M. flavovirescens 
and the range shared by M. griseoceps and T. lewcops are mutually 
exclusive, and that the latter range and that of M. papuana are not 
only mutually exclusive but probably separated by a gap of 700-800 ft. 
Local variations in the altitudinal limits of the four species are there- 
fore intercorrelated. For instance, the intrusion of tropical conditions 
at Karimui gives M. flavovirescens a higher upper limit, and T. leucops 
a higher lower limit (somewhere between 3,650 and 4,000 ft), than 
usual. Similarly, the descent of moss forest to low elevations in the 
North Coastal Range gives T. lewcops a lower upper limit, and M. 
papuana a lower lower limit (somewhere between 4,200 and 5,000 ft), 
than usual. ‘The occasional records of M. flavovirescens above 2,000 ft 
are from localities where M. griseoceps is absent. While this triple 
altitudinal sequence seems to hold for virtually all the explored high 
mountains of New Guinea, it does not apply to the zoogeographically 
distinct Fly River delta region of southern New Guinea or to the 
Cape York Peninsula of Australia, where 21 species which are con- 


257

fined to the mountains elsewhere in New Guinea, including M. 
griseoceps and T. leucops, descend to sea level. 

The differences between M. griseoceps and T. leucops, the only two 
of the five species sharing the same altitudinal range and habitat, are 
behavioral. The four Microeca species all behave in essentially the 
same manner: they are social birds, usually seen in groups of three or 
four, and perch upright and motionless, sallying out from their perches 
to catch insects. T. lewcops sometimes adopts the same behavior, but 
it seems to spend proportionately more time in the understory; it is 
often solitary, whereas I have yet to see any of the other four species as 
solitary individuals; and it often perches sideways on the bark of trees, 
a behavior I have never seen in the four New Guinea Microeca but 
which is characteristic of T. leucops’s Australian relatives and of the 
New Guinea thicket flycatchers (p. 262). In their shared altitudinal 
range T. leucops is a common and ubiquitous species, whereas M. 
griseoceps is uncommon and local. The uncommoness of M. griseoceps, 
the middle species in the three-fold sequence M. flavovirescens-M. 
griseoceps-M. papuana, with habits similar to its higher and lower 
relatives, is typical of the fate of the middle species in many three- 
species altitudinal sequences (p. 34). The numerous T. leucops has 
evidently succeeded in avoiding this “curse of the middle species” by 
adding some different habits to its behavioral repertoire. However, 
the fact that 7. lewcops has not been able to invade the altitudinal 
ranges of the successful M. papuana and M. flavovirescens, although 
it has completely overrun the range of M. griseoceps, may imply that 
many of the habits of T. leuwcops are still those of the flavovirescens- 
griseoceps-papuana group.

The three Karimui males with small testes had relatively shorter wings 
(76, 78, 81 mm) and may have been subadult.

DISCUSSION. At Karimui, Bomai, and Soliabeda this lowland 
forest species accounted for about 0.5-1.0% of the local avifauna. Its 
upper limit at Karimui (3,650 ft) is somewhat higher than usual else- 
where in New Guinea, in agreement with the general Karimui trend 
and probably related to the absence of M. griscoceps. Groups of two or 
three birds sat motionless on perches within about 15 ft of each other. 
Periodically a bird sallied out and darted around after insects, return- 
ing to the same or a nearby perch. Eventually the whole group moved 
on to a new set of perches. On three occasions my collectors brought in 
two birds shot together, and on one occasion three birds. ‘Phe compost-

new species and genus, is not separable even subspecifically from 
nominate griscoceps. Analysis of color differences in this species 1s 
complicated by marked postmortem changes, as also noted by Rand 
(1942b, p. 483). My Okasa specimen has the wing longer than in nomi- 
nate griseoceps and the back brighter and more yellow than in com-

TAXONOMY. The immature bird from Mt. Michael has the 
legs brownish orange (only the toes bright orange), the lower mandible 
orange, and the upper mandible grayish orange, whereas the whole 
leg is bright orange and the bill black in adults. ‘The uppertail of the 
immature is brownish, and the underparts a dirty lemon-green instead 
of the bright yellow of adults. 


BREEDING. Gonads were small in all Mt. Karimui specimens. 


DISCUSSION. Microeca papuana is widespread in montane forest 
of the Eastern Highlands up to about 8,500 ft. In the Okapa area 
M. papuana descended to 6,600 ft and T. lewcops occurred up to 
5,800 ft, while the corresponding altitudes for Mt. Karimui were 
6,100 and 5,400 ft. Thus, there is a gap of 700-800 ft between the two 
species. ‘he transition takes place 400-500 ft higher in the Okapa area 
than on Mt. Karimui, in agreement with the general trend for these 
areas. M. papuana ranges from the understory to about 60 ft above the 
ground in groups of three or four birds which may be in several dif- 
ferent trees spread over a distance of 50 ft and which fly to a new 
perch at intervals of 5-15 sec. On four occasions two birds out of a 
group were collected. ‘Three of these pairs proved to be a male and a 
female, while the fourth was a female plus a bird of uncertain sex, 


probably another female or an immature because of its short wing 
(69 mm). 


VOICE. ‘The song is a high, brief, tinkling, formless warble remi- 
niscent of Malurus alboscapulatus and descending in pitch. ‘The calls 
are a high-pitched “‘tsee”; a very faint, sibilant upslur; and five to 
eight repetitions of a dry, scolding note on the same pitch.

TAXONOMY. The Okasa series compares well with a topotypical 
wahgiensis female from the Kubor Mountains and with wahgiensis 
from Mafulu and the Mambare River, in the white chin and yellow 
throat, the white forehead, and the color of the bill, which is pale 
straw-orange except for a black tip to the upper mandible. ‘The Mt. 
Karimui specimens agree in these respects but have the crown blacker, 
less washed with olive. There is no size difference between the Okasa 
and Mt. Karimui series.

males, in the sole Karimui male, and in two males and one female 
from Okasa. 

DISCUSSION. Tregellasia leucops is common and widely distrib- 
uted in hill forest between about 3,000 and 5,500 ft. Its maximum 
abundance was reached in the Okasa forest (3,550-4,250 ft) and in Zone 
2 of Mt. Karimui (4,400-4,750 ft), where it accounted for about 2% 
of the local avifauna. On Mt. Karimui it dropped out at 5,400 ft, and 
the sole Miarosa specimen (5,800 ft) was an immature. It was virtually 
absent at Karimui (3,650 ft) despite the favorable altitude but in line 
with the general tropical pattern there. The sole Karimui specimen 
was not the expected immature at the limit of the species’ range but 
an adult male with large testes. ‘The habits of this flycatcher were 
mentioned on p. 258. 

VOICE. Whereas the four widespread New Guinea species of 
Microeca have weak but musical warbled songs, I heard no song or 
musical notes from Tregellasia leucops despite most of the males 
being in breeding condition. ‘Vhe call is a dry, nasal “chew” or a thin, 
nasal series of about nine scolding notes dropping somewhat in pitch 
toward the end of the series.

BREEDING. Gonads were small in all specimens. 


DISCUSSION. Monachella muelleriana is one of the two strictly 
riparian species of passerines in New Guinea, the other being Grallina 
bruijni. Its habitat is streams which (a) are rushing, (b) have many 
protruding boulders, and (c) are sufficiently broad to have an air space 
free of vegetation over them. In practice, I encountered Monachella 
muelleriana on all Eastern Highlands streams I visited between 1,350 
and 4,500 ft with beds at least 15 ft broad, but not on brooks com- 
pletely covered by forest. It disappears from lowland rivers below the 
fall line, where the streams start to meander and the banks and bed 
are no longer strewn with boulders. 

In this habitat Monachella is uncommon but widespread, perching 
motionless on boulders, fallen logs, and driftwood in the torrent or 
else on an overhanging branch, occasionally flicking its tail or sallying 
out after insects. It is a social species, usually seen in groups of three or 
four, sometimes up to eight, infrequently singly. After each member of 
the group has made a few sallies, the group flies a short distance 
along the river with a characteristic undulating flight, just a few feet

above the water. In both its social habits and its pattern of alternating 
periods of sallying with periods of perching motionlessly, Monachella 
muelleriana resembles the species of the genus Microeca. 

VOICE. A high-pitched, sweet, piping note “pink” given singly or 
rapidly repeated five to eight times.

STOMACH CONTENTS. Insects. 


DISCUSSION. Five specimens ot this uncommon high altitude 
robin have been taken in the Eastern Highlands: one collected by 
Bulmer at 11,500 ft on Mt. Hagen in bushes of the alpine grassland; 
and two at 11,000 ft in the Lamende Range, plus two more at 10,000- 
11,000 ft on Mt. Giluwe, obtained by Shaw-Mayer. I did not find it on 
Mt. Michael, nor did Gilliard on Mt. Wilhelm. 


Niche Differences Among ‘Thicket Flycatchers 


For convenience the name thicket flycatcher may be applied to 
muscicapids of the genera Poecilodryas, Peneothello, Heteromytas, and 
Pachycephalopsis, which link Petroica to Pachycephala. Most thicket 
flycatchers have similar habits, size (20-40g), and body form; the generic 
lines among them are not entirely clear (Mayr, 1941la). Eight species 
have been found to date in the Eastern Highlands: Poecilodryas 
hypoleuca, Poecilodryas placens, Poecilodryas albonotata, Peneothello 
sigillatus, Peneothello cyanus, Peneothello bimaculatus, Heteromyias 
albispecularis, and Pachycephalopsis poliosoma. Poecilodryas albo- 
notata lives in the middle- and upperstories, but the other species live 
mainly in the understory and are rarely seen more than 6 ft above the 
ground, so that mistnets have proved a boon to studying their distribu- 
tions. At least six (Poecilodryas hypoleuca, P. placens, P. albonotata, 
Peneothello sigillatus, P. cyanus, Heteromyias albispecularis), and prob- 
ably all, have the distinctive habit of perching sideways on the bark 
or stems of vertical saplings or tree trunks with the body held hori- 
zontal, a habit shared by some other related muscicapids of the genera 
Tregellasia, Eopsaltria, Quoyornis, and Petroica. Like flycatchers of 
genus Petroica, the thicket flycatchers move in a characteristic fashion: 
they remain perched motionlessly for long periods, sometimes holding 
apparently awkward postures and appearing tense and ready to pounce, 
then abruptly fly several yards further to a new perch. Flycatchers of 
genus Pachycephala, to which the thicket flycatchers show some re- 
semblance and in which a few of the species were formerly placed, may 
also perch motionless for short times but have less abrupt transitions 
between motion and rest. 

The three commonest species sort out on the basis of altitude, ap- 


262 


SPECIES ACCOUNTS 


parently with sharp transitions and no overlap: Pachycephalopsis 
poliosoma at low altitudes (ca. 3,000-5,000 ft), Peneothello cyanus at 
middle altitudes (ca. 5,000-8,000 ft), and Peneothello sigillatus at high 
altitudes (ca. 8,000-11,000 ft). The Pachycephalopsis poliosoma-Penco- 
thello cyanus transition provides one of the few cases in New Guinea 
of strict altitudinal exclusion between two species which are not 1m- 
mediately derived from a common ancestor. Poecilodryas hypoleuca 
is widely distributed in the lowlands and could be considered a fourth, 
low-altitude equivalent of the triple sequence Pachycephalopsis polio- 
soma-Peneothello cyanus-Peneothello sigillatus, but its altitudinal ceil- 
ing is well below the lower limit of Pachycephalopsis poliosoma. 

Poecilodryas albonotata shares most of the altitudinal range of 
Peneothello cyanus and the lower part of the range of P. sigillatus, 
but differs from both in its preference for the middle- and upperstories. 
Heteromyias albispecularis has an altitudinal range similar to that of 
Peneothello cyanus but is less common and spends more of its time 
actually on the ground. Peneothello bimaculatus is local in its distribu- 
tion, is largely (but not entirely) confined to the southern watershed, 
and is found in hill forest in the lower part of the altitudinal range 
of the heavier and commoner Pachycephalopsis poliosoma. Poecilo- 
dryas placens has an extremely local distribution (only six localities in 
New Guinea) below the altitudinal ranges of the other species, except 
for Poecilodryas hypoleuca.

DISCUSSION. Of the passerines with a wide geographical range 
on the lower hill slopes of New Guinea, few have a patchier distribu- 
tion than Poecilodryas placens. It is known from six far-flung localities: 
the summit of Mt. Besar on the island of Batanta off the western tip 
of New Guinea, at 2,800-2,900 ft; the Menoo Valley in the Weyland 
Mountains of western New Guinea, at 1,000-3,300 ft; Keku on Astro- 
labe Bay in northeastern New Guinea; southeastern New Guinea 
(Kubuna, Brown River, Goldie River, Mt. Cameron, and mountains 
of the Kotoi District); Lake Kutubu (2,450 ft); and the Karimui area, 
at 2,000-3,650 ft. At some of these localities P. placens is apparently 
not uncommon, although quite unobtrusive. For example, it accounted 
for 0.9% of the local avifauna at Soliabeda; Stein took 18 specimens 
in the Weyland Mountains; and Gilliard collected eight on Batanta. 
It is highly improbable that these six localities uniquely possess some 
habitat feature required by P. placens: its habits are similar to those 
of several other thicket flycatchers which are numerous, widespread in 
their altitudinal ranges, and among the dominant lowerstory fly- 
catchers. The only guess I can hazard is that P. placens may be too 
similar ecologically to the more successful P. hypoleuca to coexist with 
it and is in the process of becoming extinct. ‘his is suggested by the 
fact that at four of the six localities where P. placens has been found, 
P. hypoleuca is missing (Batanta, Karimui, most of southeastern New 
Guinea) or else present but much rarer than P. placens (Menoo Valley). 

In the Karimui area P. placens was found only in the most shaded 
parts of the forest, where the understory was relatively open. Here it 
remained strictly within 6 ft of the ground. Even more frequently than 
other thicket flycatchers it perched on the vertical stems of small trees, 
one leg an inch above the other, gripping the stem, holding the body 
horizontal and leaning outward on the extended legs, and giving an 
impression of intense concentration as it peered ahead. It held these 
uncomfortable-looking perches without moving for long times, but 
when it finally moved it did so abruptly and flew on to another stem

a few yards away or occasionally alit on the ground. I saw only solitary 
individuals, though a male and a female were once collected together. 
Apparently the only other published field observations of P. placens 
are those, of Stem (1936, p. 39). 

VOICE. The call is a buzzy squawk, but the song is one or the 
loveliest in New Guinea. The pitch is moderately low, the volume 
subdued, and the quality mellow and flute-like. Notes begin with a 
clear and sharp attack, like a bell or like the pipes of a good Baroque 
organ. The pattern consists of one to three connected pairs of notes 
with a brief pause between each pair, delivered at a rate of about 
three pairs in 2 sec (Fig. 29). The first note of each pair is higher than 
the second by an interval that may be up to a major third, particularly 
for the second and third pairs of a song, while the pitch interval in the 
first pair is often so small as to give the impression of one longer note 
on the same pitch. Usually the lower members of all two or three pairs 
are on the same pitch, but in one case the third pair was entirely 
below the pitch of the second pair. Once I heard a song consisting of 
five single notes on progressively lower pitches but with the usual 
quality.

TAXONOMY. The race correcta of southeastern New Guinea and 
the Huon Peninsula differs from this series in being paler above, hav- 
ing the white of the underparts more extensive and buffy, and the 
black of the throat paler. The Awande specimen, from my farthest 
east station, approaches correcta in having the greatest extent of 
white on the underparts of my series, more than any griseiventris 
specimen available for comparison and more than some correcta. 
However, it lacks the buffy tinged underparts and paler upperparts 
of correcta. ‘The Mt. Michael and Mt. Karimui specimens agree in 
color with griseiventris except in having the throat blacker and less 
brown, possibly because of foxing in the older material. P. a. correcta 
averages slightly smaller than griseiventris from western New Guinea, 
but the Awande and Mt. Michael males (listed as “a” and “‘b” above) 
plus one male taken at Nondugl by Gyldenstolpe (1955, p. 107: wing 
given as 97 mm) are smaller than the Mt. Karimui birds or any other 
specimen of grisetventris and smaller than most correcta.

DISCUSSION. Poecilodryas albonotata is widely distributed but 
uncommon in forest at 6,000-9,000 ft. It perches upright and motion- 
less at 20-70 ft above the ground, sometimes in the understory, holding 
the perch for 10-60 sec before flying with a loud fluttering of wings 
to the next perch 20 ft or more away. Occasionally it slowly raises and 
lowers its tail. Its insect food is either captured in midair or plucked 
off the vegetation. 

VOICE. ‘The song is at the highest pitch of any New Guinea bird 
song: two to four identical, thin, drawn-out downslurs, repeated at

much more extensive and in that the innermost secondary lacks a 
black tip. The Mt. Michael and Mt. Karimui series show no dilfer- 
ences in the wing patch, with white being confined to three secondaries, 
which have extensive black tips. ‘The wing patch is of the same size 
in nominate sigillatus from southeastern New Guinea, Mts. Wilhelm 
and Kubor, and the Schrader Range, but the one available specimen 
of saruwagedi from the Huon Peninsula has somewhat more extensive 
black tips. Measurements of wing length gave: saruwagedi, 1 9? 88; 
P. s. sigillatus, Mts. Wilhelm and Kubor, 4 ¢, 92, 93, 94 and 96, 5 ¢9@, 
89, 92, 94, 95, and 96 mm. Smaller size was cited as a characteristic of 
saruwagedi compared to sigillatus in the original diagnosis (Mayr, 
1931, p. 680), but use of this as a racial characteristic is complicated 
by an increase of size with altitude at the same location (Mayr and 
Rand, 1937, p. 159; Rand, 19425, p. 485). My semes may, therefore, 
be assigned to sigillatus and is quite distinct from hagenensis. It is 
surprising that these two subspecies occur 30 miles apart (the distance 
between Mt. Hagen and Mt. Kubor), since most other high altitude 
species are represented by the same subspecies on different peaks of 
the Eastern Highlands. 

The immature has the uppertail largely black, the upperparts largely 
black but mixed with increasing numbers of rufous feathers towards 
the head, and the underparts mottled rufous and dark gray, with 
rufous predominating. 


DISCUSSION. Peneothello sigillatus is the thicket flycatcher of the 
moss forest and seems to be the high-altitude equivalent of P. cyanus. 
On Mt. Michael, where moss forest begins at 8,700 ft, P. cyanus went 
up at least to 8,100 ft, and P. sigillatus extended from 11,000 ft, near 
timberline, down to at least 9,500 ft. On Mt. Karimui, where moss 
forest descends to 6,500 ft, the transition between P. cyanus and P. 
sigillatus took place around 7,000-7,300 ft. P. sigillatus usually remains 
within a few yards of the ground or on the ground itself, changes 
perches at intervals of 5-20 sec, and often perches sideways on saplings. 
Once I saw it in a tree fern in alpine grassland 40 ft from the forest 
edge.

eastern New Guinea birds, and paler than in specimens from ‘Tele- 
folmin, the Cyclops Mountains, or the Snow Mountains. Mt. Karimui 
specimens are darker in general coloration than those from Awande. 
These and other Eastern Highlands series of P. cyanus are slightly 
larger than suwbcyaneus from southeastern New Guinea. There is no 
size difference between Awande and Mt. Karimui birds, nor is there 
a change of size with altitude on Mt. Karimui. 


BREEDING. Gonads were enlarged, usually greatly, in almost all 
Mt. Karimui adult males and in two of the three adult males taken 
at Awande in 1965. No immature birds were taken on Mt. Karimui. 


DISCUSSION. Peneothello cyanus is the thicket flycatcher of forest 
from about 5,000 ft up to the level at which heavy mossing appears. 
Its abundance shows puzzling variability. On Mt. Karimui (west peak), 
where it occurred from 5,200 to about 7,000 ft, it was the commonest 
flycatcher and the fourth most abundant bird in this zone, accounting 
for about 6% of the local avifauna. At some other localities it is 
uncommon or even absent. 

Its behavior is similar to that of Poecilodryas placens, i.e., it gen- 
erally remains within 5 ft of the ground (though I have also seen it as 
much as 15 ft up) and remains motionless at a perch, appearing to peer 
intently, before abruptly flying on to another perch. 

VOICE. ‘The song is similar to that of Myzagra alecto: a series of 
a dozen clear, musical, whistled notes at medium pitch, the first few 
of which are on the same pitch, but they then progressively rise in 
pitch and accelerate (Fig. 29, left, p. 266). ‘The volume remains un- 
changed or else progressively increases only slightly. A less common 
song with a very different quality is a loud, unmusical, three-note 
phrase repeated several times and preceded by one or two other notes 
(Bie. 29, mene).

latus from the Vogelkop, the Weyland Mountains, the southern slopes 
of the Snow Mountains, and the southern slope of southeastern New 
Guinea. The race vicarius is distinguished by having almost no white 
on the belly. Snow Mountains birds assigned to bimaculatus have the 
next least amount of white on the belly. ‘The other series of bimacu- 


268 


SPECIES ACCOUNTS 


Jatus (including mine) show individual variation in the amount of 
white but no average differences between series. “he extent of white 
in the breast patch also shows individual variation but not average 
variation between series. The depth of blackness of most of the body 
plumage varies; this color has a brownish tinge in all comparative 
material and in my females and immatures, but my males stand out 
at once as being fully black. Foxing may be part or most of the ex- 
planation in this case, since one male collected by Gilliard in the 
Tamrau Mountains of the Vogelkop in 1964 is as black as my males 
and blacker than prewar Vogelkop males. ‘The two immatures have 
brown tips to the upperwing coverts. ‘Table 7 shows that there is little 
size variation, except that Snow Mountains birds are distinctly smaller. 
The Snow Mountains population may eventually require naming on 
the basis of small size and reduced extent of white on the belly, but 
a larger series is required to confirm these differences.

DISCUSSION. Peneothello bimaculatus resembles Poecilodryas 
placens in being an “unsuccessful” thicket flycatcher with a patchy 
distribution, though it is not so extreme a case. It has turned up at 
about 15 scattered localities in southern New Guinea extending around 
to the Adelbert Mountains in the northeast and the Weyland Moun- 
tains in the northwest, but it is apparently absent in most of northern 
New Guinea (i.e., no records from the northern slopes of the Central 
Range, the Cyclops Mountains, or the North Coastal Range). In the 
Eastern Highlands I met P. bimaculatus only at Karimui and Bomai. 
When seen, it was perched a few feet above the ground in under- 
brush in forest or at the edge of forest, sitting motionless except for 
occasionally flicking its wings.

Despite their intermediate geographical position they show no ap- 
proach to the brownish black crown of armiti of the Herzog Moun- 
tains and southeastern New Guinea (the crown is black instead), but 
the Awande and Miarosa specimens do approach slightly the brighter 
and more olive back of armiti. 

BREEDING. Gonads were large in the female and one male from 
Awande, small in the other Awande male. 


DISCUSSION. Heteromyias albispecularis is present, though un- 
common, at most forest localities in the Eastern Highlands between 
5,500 and 8,500 ft, but was absent on Mt. Karimui. It frequently 
perches on the ground. 


VOICE. A ringing, bell-like note repeated 4-8 times per second 
for up to 15 sec without change of pitch or volume. A fragment of 
this song two to five notes long is often given as a call. The call of 
Climacteris leucophaea, a midmontane species which is absent from 
the Eastern Highlands, is quite similar but crescendoes slightly. An- 
other song of H. albispecularis consists of three or four clear, high- 
pitched, whistled notes going up the scale and is the origin of the Fore 
name “‘yo-ba-go”’.

TAXONOMY. ‘The Eastern Highlands series was compared with 
albigularis (type and two other topotypical specimens from the Wey- 
land Mountains, plus two from ‘Telefolmin), approximans (southern 
slope of the Snow Mountains, four specimens), balim (the type from 
the northern slope of the Snow Mountains at higher altitudes), iden-

specimens), /rypopolia (Huon Peninsula, one specimen), and nominate 
poliosoma (southeastern New Guinea and Herzog Mountains, many 
specimens). Eastern Highlands birds are close to topotypical albigu- 
laris, particularly in the dorsal coloration, and differ mainly in the 
bluer, less gray underparts and the darker uppertails, in both of which 
deviations they resemble ‘Teleformin birds. It was initially surprising 
when Telefolmin birds, separated from the Weyland Mountains by 
300 miles and the populations of idenburgi and balim, had to be as- 
signed to albigularis (Gilliard and LeCroy, 1961, p. 59). It is even more 
surprising that birds from the southern slope of the Eastern High- 
lands, 500 miles to the east of the Weyland Mountains and on the 
opposite watershed, are also albigularis. Of the two other southern 
watershed races, approximans differs in the more eray-brown and less 
blue upperparts, the grayer and less blue underparts, and the much 
lighter and browner uppertail, while nominate poliosoma is duller, 
more gray-brown and less blue above (especially on the crown), lighter 
on the exposed parts of the upperwing and tail, more gray-brown and 
less blue below (especially on the breast), and has the white of the 
throat more restricted in extent and more washed with gray-brown 
posteriorly. Compared to Mt. Karimui specimens, Okasa specimens 
show a slight tendency towards nominate poliosoma in the bufher and 
less extensive throat patch, but they are still much nearer albigularis. 
The race balim differs in having the back, crown, and breast more 
gray-brown and the undertail coverts buffy, not gray; tdenburgi 1s 
smaller, grayer below, has the extent of white on the throat more 
reduced, and the margins of the remiges browner; and hypopolia is 
smaller, paler, and grayer on the back and crown, more gray-brown 
below, and the extent of white on the throat is more restricted. No 
specimens of the race hunsteini (mountains on the upper Sepik River) 
were available, but from the description it must differ in the reduced 
extent of white on the throat and in other respects. 


BREEDING. Gonads were small in Okasa specimens except one 
male, which had greatly enlarged testes. At Karimui gonads were 
greatly enlarged in males and in one female. On Mt. Karimui testes 
were moderately enlarged in one male, slightly in two, not at all in 
three; and ovaries were enlarged in only two females. 


DISCUSSION. P. poliosoma is the common thicket flycatcher of 
the hill forest (3,000-5,000 ft). However, it is so shy and hard to see 
that it may be overlooked completely unless one learns its song or sets 
up mistnets. Song censuses and netting returns show that it reached 
its maximum density in Zone | of Mt. Karimui (4,000-4,200 ft), where 
it was the most abundant bird and accounted for 12% of the local 
avifauna. Between 5,100 and 5,200 ft in Zone 3 of Mt. Karimui it was 
abruptly replaced by Peneothello cyanus, altitudinal exclusion between 
the two species being strict. (In the Daribi language spoken at Karimui 
Peneothello cyanus and Pachycephalopsis poliosoma go by the same 


271 


SPECIES ACCOUNTS 


name, “karoabo”). At Karimui, on the floor of the Karimui Basin, 
Pachycephalopsis poliosoma was much less common (0.7% of the local 
avifauna), and the lowest record of it was at 3,230 ft en route to 
Soliabeda. When seen, it was always solitary, in the forest interior, and 
perched stationary for relatively long times within a few feet of the 
forest floor. 

VOICE. ‘The call is a single whistled note, often slightly upslurred, 
rather loud, and with considerable carrying power and a clear, piercing 
quality, like the sound produced by blowing across the open end of an 
expended shotgun cartridge. The song (Fig. 29, p. 266) consists of four 
to seven, usually four or five, notes with a very buzzy quality. Each note 
is upwards inflected and about half a tone higher than the previous 
note. Ihe time intervals are slightly less than 1 sec between the first 
few notes and distinctly shorter between the last two or the last three 
notes. Both the song and the call are heard often, and particularly the 
song is easily recognized.

WING. 10 4: 62-68 (65+ 2). 4 9: 62, 63, 63, 64. 

TAXONOMY.  Pachycare flavogrisea shows considerable geographi- 
cal variation in the depth of its yellow ventral color. The race randi 
of the northern slope of the Snow Mountains has the deepest and most 
orange color, followed by swbaurantia of ‘Yelefolmin and the southern 
slope of the Snow Mountains, followed by nominate flavogrisea of the 
Vogelkop, followed by swbpallida of southeastern New Guinea, the 
palest and most yellow race. Where swbaurantia grades into subpallida 
in the Sepik Mountains, birds resembling nominate flavogrisea are 
found. Unfortunately, the color fades markedly within the first ten 
years postmortem, so that subspecific assignment of fresh specimens 
involves an educated guess as to what their appearance will be in ten 
years. For instance, Weyland Mountains birds collected by Stein in 
1931 “agreed completely” with topotypical swbaurantia in 1935 (Har- 
tert, Paludan, Rothschild, and Stresemann, 1936, p. 202) but “agreed 
perfectly” with topotypical P. f. flavogrisea when reexamined in 1940 
(Rand, 1942b, p. 487). When I examined my specimens (collected in 
1964 and 1965) in March of 1966, I found that the Karimui series was 


272 


SPECIES ACCOUNTS 


approximately as orange as subaurantia from ‘Telefolmin (collected 
in 1954, so that fading was probably completed) and was considerably 
more orange than the Okasa series which agreed with nominate flavo- 
grisea. In February 1967 I reexamined the specimens and found that 
Karimui birds were still swhaurantia but that Okasa birds were inter- 
mediate between flavogrisea and subpallida. It seems a safe guess that 
the Okasa series will finally fade into suwbpallida. 1 am provisionally 
listing the Karimui birds as swbaurantia, but it remains to be seen 
whether they will reach the level of flavogrisea by the time they finish 
fading. In any case, the general increase in orange color from east to 
west (exclusive of the Vogelkop) is reflected in the difference between 
Okasa and Karimui, 100 miles west of Okasa. 

BREEDING. Gonads were small in all Okasa specimens except 
one male; large in both Karimui males; and small on Mt. Karimui 
except for being quite large in one male and slightly enlarged in 
another. 

DISCUSSION. Pachycare flavogrisea is a characteristic, vocal, and 
common species of hill forest from about 2,800 to 5,400 ft, reaching its 
maximum abundance in Zones 1, 2, and 3 of Mt. Karimui (4,000-5,400 
ft, 6% of the local avifauna). There seems to be no tendency to stray 
above its local altitudinal ceiling, although the level of the ceiling 
shows minor local differences. While P. flavogrisea is sometimes found 
in low trees in open second-growth if there is forest nearby, it is 
commonest in forest. It can be seen at almost any height in the vegeta- 
tional column from a few feet above the ground to the crowns of trees 
but is found most often in the middlestory. It is usually solitary, 
fairly active, and much more often heard than seen. 


VOICE. ‘The loud, melodious, whistled, and explosive calls and 
songs are among the characteristic sounds of hill forest and support 
the suspected relationship of Pachycare with Pachycephala and Col- 
luricincla. ‘These calls involve two kinds of notes: an upslurred 
“wheep!” and a nonslurred “chew!” ‘The patterns permute a rapid 
series of 2-4 “wheep’s” on the same pitch with rapid series of 2-4 
“chew’s” on some other pitch, usually several notes lower. Each series 
of “wheep’s” or “chew’s” progressively increases in volume. One of the 
commonest patterns is: “wheep-wheep! chew-chew-chew! wheep-wheep! 
chew-chew-chew! wheep-wheep! chew-chew-chew!” Figure 30 (p. 278) 
gives other patterns. The rapid tempo and the repeated crescendoes are 
distinctive, but confusion with the even louder and more explosive call 
of Eupetes castanonotus is possible. 


Niche Differences in the Genera Pachycephala, Colluricincla, 
and Pitohwi 
The species of these three closely related genera may conveniently 
be discussed together as regards niche differences.

SPECIES ACCOUNTS 


Nine species of Pachycephala have been found in the Eastern High- 
lands. Five of these are ecologically similar, similar-sized (weight ca. 
20-25 g), rather common, forest-dwelling, insectivorous species which 
form a broadly overlapping altitudinal sequence: P. griseiceps (0-4,500 
{t), P. hyperythra (1,500-4,200 ft), P. soror (3,500-6,000 ft), P. schlegelit 
(5,000-10,000 ft), and P. modesta (6,000-11,000 ft). As discussed on p. 00, 
each species partly overlaps the altitudinal range of the species above 
and below it, and the altitudinal overlap is apparently made possible 
by differences in preferred vertical foraging level within the vegeta- 
tional column. P. leucostigma, an uncommon forest species, has an 
altitudinal range that brings it into contact with all eight other 
Pachycephala species, and is similar in size to the preceding five, but 
differs in that it takes considerably more fruit than insects, while the 
other species take mainly insects and rarely fruit. P. rufinucha lives in 
the forest and overlaps the altitudinal ranges of six of its congeners 
(all those found in the Eastern Highlands except P. griseiceps and P. 
hyperythra), but differs in that it is 70°% heavier (weight ca. 40 g), has 
a more powerful bill and legs, lives mainly on the forest floor, and takes 
larger prey than its congeners as well as fruit. P. tenebrosa, a large 
(weight ca. 45 g) midmontane bird of the forest floor, is rare and known 
in the Eastern Highlands from only one locality. P. rufiventris overlaps 
all its congeners altitudinally but lives in very open groves, e.g., gardens 
or casuarinas, a habitat shared by no other member of the genus in 
New Guinea. 

Colluricincla megarhyncha is common, similar in proportions to the 
first five Pachycephala species discussed, overlaps most of them altitudi- 
nally (ca. 0-6,000 ft), and forages for insects in the lower- and middle- 
stories of the forest and second-growth, but is larger (weight ca. 35-40 g) 
and more sluggish. C. harmonica is twice as large as C. megarhyncha, 
comparable in size to the species of Pitohui, and lives in open groves, 
a habitat in which the only other whistler is the much smaller Pachy- 
cephala rufwentris. 

The species of the endemic New Guinea genus Pitohwi are about 
twice as large (70-100 g) as Colluricincla megarhyncha and take both 
insects and fruit. All five widespread members of this genus have been 
found in the Eastern Highlands. One member sorts out on the basis of 
altitude: P. nigrescens is found only above 5,500 ft, where its congeners 
are all absent. All four of the other species were able to coexist at 
Karimui (3,650 ft). P. cristatus 1s a rare species of hill forest apparently 
living mainly on the ground, whereas the other four species seem 
similar to each other in their habits and occupy both the understory 
and middlestory. P. kirhocephalus, P. dichrous, and P. nigrescens ap- 
parently form a three-species altitudinal sequence with much overlap 
between the first two and a sharp transition between the second two. 
The altitudinal ranges of P. ferrugineus and P. kirhocephalus coin-

ceiling elsewhere in New Guinea, and the ecological differences be- 
tween these two species are not clear to me. The species “Pitohui

genus Recles (= Pitohui), subsequently placed in a monotypic genus 
Malacolestes, sometimes placed in Collwricincla, and transferred back 
to Pitohui by Mayr (1967) in Peters’ Check-list, Vol. 12, appears to me 
to belong to Colluricincla and not to Pitohur.

STOMACH CONTENTS. Fruit only, ranging in diameter from 1 to 9 mm (3 
d..0 ©); fruit and imsects (6 4); insects only (2). 

TAXONOMY. In the western races nova and nominate leucostigma 
the adult male has a mottled pattern approaching that of the female. 
Compared to five adult males of obscura (one from Mt. Goliath and 
four from southeastern New Guinea), my males are darker above and 
darker and more olive below. The Mt. Goliath male is the next darkest 
and also has obscure barring on the underparts, which is present but 
less marked in my specimens and virtually absent in southeastern New 
Guinea males. ‘The iris was olive in the one adult male whose eye color 
I noted, brown in the females and immature males. 


BREEDING. ‘Testes were greatly enlarged in the Mengino adult 
and slightly enlarged in the Mt. Karimui Zone 5 adult and the Okasa 
immature. In all other specimens gonads were small. 


DISCUSSION. ‘The series clearly illustrates a tendency towards 
altitudinal specialization according to age and sex. All four adult males 
were taken above 6,000 ft (at 6,500 and 6,770 ft on Mt. Karimui, and 
at 6,100 ft at Mengino and near Awande). At Okasa (3,550-4,250 ft), 
Karimui (3,650 ft), and Mt. Karimui Zone 2 (4,700 ft) only females 
and immature males were taken. The highest specimen was the im- 
mature male from 8,000 ft on Mt. Michael. Gilliard obtained one 
specimen on Mt. Hagen and another at 8,300 ft in the Schrader 
Range. 

I have no field observations of this whistler, whose stomach contents 
consist of both fruit and insects but mainly fruit. The statement by 
Rand and Gilliard (1967, p. 422) and by Stein (1936, p. 36) that its 


1 Listed as Rhagologus lewcostigma in Rand and Gilliard (1967).

SPECIES ACCOUNTS 


diet is exclusively fruit is incorrect, as already noted by Gilliard and 
LeCroy (1968, p. 21). Presumably its diet is what enables it to coexist 
at the same altitudes and in the same habitats as six other whistlers 
(P. soror, P. schlegelii, P. griseiceps, P. hyperythra, P. modesta, and 
P. rufinucha), which take fruit infrequently. All of my specimens were 
obtained in forest, and 11 of the 13 were netted, suggesting lowerstory 
habits. 

P. leucostigma was originally described in the genus Pachycephala, 
and its close affinity to the other species of this genus has never been 
questioned. Although it has a distinctive color pattern and diet, I see 
no reason to conceal its relationships by recognizing the monotypic 
genus Rhagologus for it. Even my Fore assistants referred to P. lewco- 
stigma simply as “pitna’, the Fore name for all species of genus 
Pachycephala (but not of the genera Colluricincla or Pitohut).

TAXONOMY. Adult males have the tail blackish (as in the western 
race klossi) rather than strongly washed with olive (as in bartoni of 
southeastern New Guinea and the Herzog Mountains). ‘he more east- 
ward-lying Awande and Okasa birds are indistinguishable from Kari- 
mui birds in this respect and thus show no approach to bartont. 
Immatures have brown on the head and wings. 


BREEDING. At Awande in 1965 most specimens had the gonads 
much enlarged, and one female contained a nearly full-sized egg. On 
Mt. Karimui one adult male had the testes somewhat enlarged, another 
slightly, and the others not at all. 


DISCUSSION. P. soror has a lower altitudinal limit around 3,500 
ft and a ceiling at an altitude varying locally between 5,800 ft (Mt. 
Karimui) and 8,000 ft (Mt. Michael). It shares the lower part of its 
range with P. hyperythra, the upper part with P. schlegeli and P. 
modesta. It is similar in habits to these other species except that it 
spends less time in the understory than P. schlegeli and more time in 
the understory than P. hyperythra or P. modesta. Three of the four 
specimens at Karimui (3,650 ft), the lower limit of its altitudinal range 
in this area, were immatures, in agreement with the usual pattern of 


276 


SPECIES ACCOUNTS 


immature birds setting the lower limit of a species. Within its altitudi- 
nal range P. soror is fairly common (1-2% of the local avifauna). 

VOICE. I never identified the song with certainty. However, be- 
tween 4,750 and 5,680 ft on Mt. Karimui, a zone in which P. soror, P. 
schlegelii, and P. rufinucha were the only species of Pachycephala, I 
frequently heard a distinctive song which could only have been a 
Pachycephala and which was attributed by the Fore to a piina, their 
name for all species of Pachycephala. Since the song of P. schlegelit 
is distinctly different and I am familiar with it, and since P. rufinucha 
was considerably less common, I tentatively assume that this unidenti- 
fied song was P. soror and describe it here. ‘he commonest pattern 
(Fig. 30) consists of a fairly rapid series (ca. three notes per second) of 
8-10 very clear, whistled, high-pitched notes, all on the same pitch 
and progressively increasing in volume, and usually concluding in a 
loud slur, either upslurred or downslurred, which is occasionally 
omitted. Variants are that the individual notes in the series of 8-10 
notes may all be explosively upslurred, or else explosively downslurred, 
or else disyllabic. ‘The crescendo and the bell-like clarity of the whole 
song are distinctive.

STOMACH CONTENTS. Most stomachs contained only insects; one adult fe-

TAXONOMY. Analysis of wing length shows no change with alti- 
tude between 4,400 and 8,165 ft, although birds from 9,000 ft upward 
have been shown to be larger (Mayr and Rand, 1937, p. 173; Rand, 
1942... 403), 

The subspecific color differences cited by Hartert in defining the 
races obscurior, viridipectus, and cyclopum are very slight. In adult 
males the abdomen is somewhat more ochraceous in obscurior of south- 
eastern New Guinea than in other races. My males are intermediate 
but nearer obscurior. 

BREEDING. ‘Testes were greatly enlarged in the one male from 
Awande and in seven from Mt. Karimui; and moderately enlarged in 
six, slightly in four, and not at all in five adult males from Mt. 
Karimui.

DISCUSSION. The change in population composition with alti- 
tude as we went up Mt. Karimui was striking. In Zone 2 (4,400-4,750 It) 
my only records were of the two immatures collected, a male in female- 
like plumage and with tiny testes, and an unsexed immature with 
many scattered rufous feathers (a carryover from the nestling plumage). 
In Zone 3 an unsexed bird in female plumage was collected at 5,080 ft, 
an adult male with small testes at 5,180 ft, and an adult female at 5,210 
ft. In Zone 4 (5,390-5,960 ft) one singing male was seen and heard 
around 5,900 ft, adult females were collected at 5,700, 5,865, 5,870, 
and 5,960 ft, and the first adult male with enlarged testes was collected 
at 5,960 ft on the boundary between Zones 4 and 5. In Zone 5 an adult 
female was taken at 6,100 ft and two at 6,450 ft, an adult male with 
enlarged testes at 6,100 ft and another at 6,400 ft, three adult males 
with small testes at 6,100 ft, 6,430 ft, and 6,530 ft, a male in nearly 
adult plumage with tiny testes at 6,500 ft; and singing males began to 
be encountered regularly above 6,250 ft. In Zone 6 through 8 (6,500 ft 
up to the summit at 8,165 ft) males with enlarged testes accounted 
for more than half the population, and singing males were common. 
The contribution of P. schlegelii to the total avifauna was below 1% 
up to 5,780 ft but thereafter rose progressively from 4% in the upper 
half of Zone 4 (5,780-5,960) ft) to 11%, in the upper half of Zone 8 
(7,610-8,165 ft), where it was the second commonest bird (after Ptzlo- 
prora guiset). 

P. schlegelii is abundant and widespread in the Eastern Highlands 
in forest between about 4,400 and 9,700 ft, the exact limits varying 
locally. Whereas it descended to 4,400 ft on Mt. Karimui, in the Okapa 
area it was still very uncommon at 6,000 ft. It ranges from the under- 
story to the crowns, shifts perches every few seconds while foraging, 
and obtains its food by plucking it from surfaces rather than by 
sallying. 

VOICE. Varied, but readily recognized as a Pachycephala by the 
crescendoes, and distinguished from other species of Pachycephala by 
the frequent use of a characteristic slurred note and of unmusical 
sounds resembling the sound of smacking one’s lips, kissing, or a cat 
meowing. ‘The characteristic slur is an explosive whistled note which 
suddenly rises in pitch and then immediately returns to the original 
pitch, increasing in volume as it does so (Fig. 30, p. 278). ‘This resembles 
somewhat a call of Monarcha frater. A typical song consists of 10 such 
slurs repeated identically at intervals of slightly less than 1 sec. Another 
song is a prolonged cat-like meow which increases in volume, rises 
slightly in pitch, and is terminated by the explosive slur. Sometimes 
this song consisting of the meow and the slur is prefixed by four 
detached, identical, bell-like notes. Countersinging males snap their 
bills and flare and erect the yellow nape patch.

TAXONOMY. ‘The series is close to perneglecta from the Fly River 
and from southeastern New Guinea west of Port Moresby, differing 
slightly in that the olive back is brighter and greener and in that the 
gray of the head contrasts more with the olive back. Okasa and Karimui 
specimens are virtually the same. The race dubia of southeastern New 
Guinea east of Port Moresby is very distinct in its brown back and lack 
of yellow on the underparts. ‘The Lake Kutubu population also belongs 
to perneglecta (Schodde and Hitchcock, 1968). 


BREEDING. Gonads were small in all females and in the Okasa 
male. At Soliabeda the testes were slightly enlarged in three males, 
small in two; at Karimui, large in two males, small in two others. 


DISCUSSION. Pachycephala griseiceps will probably be found in 
most areas of the Eastern Highlands from about 4,500 ft down to sea 
level. It occurs in forest but is more numerous at the forest edge and 
comes out into partly cut forest and dense second-growth. Its altitudi- 
nal range includes the lowest part of P. soror’s range, the entirety of 
P. hyperythra’s range, and the lowlands, where no other member of the 
genus is present. Whereas P. hyperythra, P. soror, and P. schlegelit 
spend much of their time in the understory, P. griseiceps is usually 
found at least 15 ft above the ground in the middlestory or in the 
crowns, descends less frequently to the understory, and is rarely taken 
in mistnets. 

VOICE. <A melodious chirping which is unmistakable once learned. 
The pattern consists of a strict alternation between a monosyllabic, 
slightly upslurred chirp and a disyllabic chirp. Each kind of chirp is 
given alternately a few to a half dozen times and returns at intervals 
of between 1% sec and | sec. ‘The most distinctive and charming feature 
is the flexibility both of tempo and volume, reminiscent to an exag- 
gerated degree of a Chopin waltz played rubato. ‘The singer unpredict- 
ably and irregularly doubles his rate of delivery while increasing the 
volume. At the same time the disyllabic chirp, which is at a lower 
pitch than the monosyllabic chirp at a slow rate of delivery, moves to 
a pitch higher than that of the monosyllabic chirp. ‘The song is ventrilo- 
quial, and the singer often hard to identify even when in open view. 
Only when I succeeded in observing the throat of a P. griseiceps mOov- 
ing in synchrony with the song could I finally prove that it was the 
author. Among other species of Pachycephala the only foreshadowing

TAXONOMY. Compared with salvadori: of southeastern New 
Guinea, these specimens agree in the pale, dull ochraceous underparts, 
the gray throat, and the dark and slightly brown-tinged olive back, 
and differ only in the slightly brighter color of the belly. ‘The races 
sepikiana and nominate hyperythra differ in the brighter and more 
orange underparts; retchenowi in the brighter underparts, browner 
back, and whiter, less gray, throat. The Lake Kutubu population also 
belongs to salvadorii (Schodde and Hitchcock, 1968). A single speci- 
men, in poor condition, obtained by the Second Archbold Expedition 
on Mt. Mabiom at the headwaters of the Fly River, is brighter olive 
above and somewhat brighter ochraceous below than my series. ‘Thus, 
there appears to be a cline on the southern watershed, with increasing 
brightness from southeastern New Guinea to the Karimui area to the 
Fly River to nominate hyperythra of the Vogelkop. 

BREEDING. Gonads were enlarged in one Soliabeda male but 
small in all other specimens. 


DISCUSSION. P. hyperythra is the whistler corresponding to P. 
soror and P. schlegelii in the lower hill forest, with an altitudinal 
range of about 1,500-4,200 ft. From Soliabeda it extended up on Mt. 
Karimui only to 4,200 ft and failed to overlap P. schlegelii (found 
above 4,400 ft) but did overlap P. soror (found above 3,650 ft). Inthe 
Eastern Highlands it remained at 10-30 ft above the ground, and I 
never netted it. In the North Coastal Range, where P. soror was 
missing, P. hyperythra was frequently seen in the understory and was 
netted. 

While P. hyperythra’s geographical range covers most of New 
Guinea, its local distribution has the curious patchiness which one 
comes to associate in New Guinea with genera containing many eco- 
logically similar species (p. 25). I failed to find it at Okasa (3,550-4,250 
ft), although the altitudinal range would appear suitable. In south- 
eastern New Guinea it is known from few localities; it is not included 
in the exhaustive collections of the First Archbold Expedition, and 
neither Mayr nor Stevens encountered it in the Herzog Mountains. 
There are no records at all from the southern slope of the Snow 
Mountains, although the hill forest zone there has been explored at

many points by six large expeditions. At several localities where P. 
hyperythra is absent, P. soror, whose lower limit in the presence of 
P. hyperythra is around 3,500 ft, ranges down to 2,000 ft or lower and 
appears to take over P. hyperythra’s altitudinal range. 

VOICE, A typical Pachycephala song, beginning with 1-8 clear, 
faint, bell-like or whistled notes that crescendo and terminate in loud, 
usually repeated slurs ““whik! whik!” (Fig. 30, p. 278).

TAXONOMY. Specimens from my three localities are very similar 
to each other and to birds collected on Mt. Kubor by Gilliard. ‘The 
nominate race is more olive and generally lighter on the back, while 
telefolminensis is grayer below and darker and grayer on the back. 


BREEDING. ‘The Mt. Karimui female contained a nearly full- 
sized ege. 

DISCUSSION. In the areas where I collected, P. modesta was the 
least common Pachycephala and the one with the highest altitudinal 
range, extending from 6,000 ft to timberline at 11,000 ft. While oc- 
casionally seen in the understory, it usually remained in the crowns 
40 or more feet above the ground, where it foraged both by plucking 
and sallying and moved by frequent short hops of a few feet alternating 
with short flights. At at least two localities in southeastern New Guinea 
P. modesta descends to considerably lower altitudes: to ca. 3,500 ft in 
the Herzog Mountains (Mayr, 1931, p. 716) and to 4,200 ft in the 
Owen Stanley Range inland from Port Moresby (Gilliard, 1950, p. 30). 
The only guess I can hazard for an explanation is that, since this is an 
area where P. hyperythra is missing, the remaining Pachycephala 
species may have expanded their niches and altitudinal ranges. 

P. modesta is one of only five species of montane birds confined to 
eastern New Guinea and lacking a western New Guinea representative 
in the same superspecies. However, there is a close relative of P. 
schlegelii, P. lorentzi, which is confined to western New Guinea, oc- 
cupies there a high altitudinal range (ca. 6,000-12,500 ft) similar to 
that of P. modesta in eastern New Guinea, and may fill an analogous 
niche. P. modesta and P. lorentzi to date have been found sympatric 
only at Telefolmin.

TAXONOMY. Although Rand and Gilliard (1967, p. 429) keep 
as distinct species P. rufiventris of Australia, southeastern New Guinea, 
and the Louisiade Archipelago and P. monacha of the rest of New 
Guinea and the Aru Islands, the evidence summarized by Mayr and 
Gilliard (1954, p. 352) for considering them conspecific seems con- 
vincing. The two “‘species” intergrade in the vicinity of Port Moresby. 

DISCUSSION. Prior to the ornithological exploration of the 
Eastern Highlands P. r. dorsalis had been considered a rare bird, known 
only from seven scattered localities. In the Eastern Highlands it is 
common, loud, and conspicuous in tall casuarina trees growing on 
lawns in European settlements. It may also be found, but more 
erratically, in trees at the edge of the forest or trees in native gardens 
and villages. Possibly it is a very recent arrival in the Eastern High- 
lands and is spreading rapidly; Paran told me that it had settled at 
Awande for the first time in 1963. It has also colonized (or is coloniz- 
ing) settled areas in the Baliem Valley, at Teleformin, and in the 
‘Torricelli Mountains. 

The perches of P. rufiventris range from 15 ft above the ground to 
the tops of tall casuarinas. I have seen it catching insects on the wing 
and also eating a caterpillar. 

VOICE. ‘The song is a typical whistled Pachycephala song but 
more explosive than that of other New Guinea species. Most songs 
end in an explosive, slurred (either up or down), whistled “whoop” 
or ““wheep” or “chew”. This is preceded either by a single long note 
on constant pitch, by a rapid series of staccato notes on the same pitch 
separated by identical brief time intervals, or by a rapid series of 
identical slurs. Whichever is the case, this introductory note, notes, or 
slurs increase dramatically in volume to terminate in the final ex- 
plosive slur. All notes are clear and whistled; there are no unmusical 
notes such as occur in the songs of P. hyperythra and P. schlegelii 
(Big. 30, p. 2738),

south coast of southeastern New Guinea, superfluus (including the 
type) from the north coast of southeastern New Guinea, nea from the 
Herzog Mountains, madaraszi from the Huon Peninsula, and tap- 
penbecki from northeastern New Guinea and the Kubor Range of 
the Eastern Highlands. My specimens are closest to nea, with which 
they agree in the dark gray bill and the gray throat, and from which 
they differ only in having slightly darker upperparts and brighter 
underparts. The race palmeri from the Fly River is also close but 
differs in the buffier and less gray throat, the more straw-colored bill, 
and the slightly more distinct breast streaks. Awande-Okasa_ birds 
average very slightly brighter olive above, less heavily streaked on the 
breast, and less dull or gray below than birds from the Karimui area 
when large series are viewed side by side. There is no convincing 
change of weight or wing length with altitude in either the Awande- 
Okasa area or the Karimui-Bomai-Soliabeda-Mt. Karimui area, but 
birds from the former area are slightly heavier and have longer wings 
than birds from the latter area. The race goodsoni is much paler and 
duller above, particularly on the crown, and much less olive above; 
wuro? is paler above and less gray on the chin; despectus is paler above 
and below and slightly more olive above; superfluus is paler, duller, 
and less ochraceous below; madaraszi is less olive above; tappenbecki 
is browner, duller, and less olive above, and the throat and upper 
breast are grayer and contrast more with the belly. Birds from the 
Wahgi Valley and Mt. Giluwe, collected by Gilliard, Gyldenstolpe, 
and Shaw-Mayer, are tappenbechi. 

BREEDING. Gonads of most specimens were large at Awande but 
small at other localities. 

DISCUSSION. Colluricincla megarhyncha is inconspicuous and 
solitary but nevertheless common and ubiquitous from sea level up to 
a ceiling which varies locally between 5,400 and 6,500 ft. On Mt. 
Karimui it dropped out at 5,400 ft, but it was still common around 
6,100 ft at Mengino and 6,200 ft at Awande, while Bulmer found it 
up to at least 6,500 ft in Kyaka territory. Its habitat is the lower- and 
middlestories (to ca. 10-15 ft above the ground) in the forest interior, 
at the forest edge, and in second-growth which is sufficiently dense for 
the understory to be well shaded. In these habitats it accounts for 
about 3-59% of the local avifauna. 

In behavior, posture, appearance, and voice C. megarhyncha is 
simply a big and sluggish Pachycephala. Some specimens had to be 
examined carefully to distinguish them from the dull race of Pachy- 
cephala hyperythra living in the Karimui area. 

VOICE. ‘The song is the origin of the South Fore and Gimi name 
“kokopilo” and consists usually of four notes, the last two of which 
are joined in an upslur or downslur (Fig. 31). There is a strong but not 
explosive increase in volume in the last two notes. The first note is 
approximately a major sixth in pitch above the second. Sometimes an 


285

extra note is added at the beginning, creating a five-note song. The 
total length is about 11% sec, the quality is mellow, and the pitch some- 
what lower than that of Pachycephala rufwentris. It was amusing to 
hear hidden individuals give their song after every gunshot, a useful 


attribute that made it easy to determine the altitudinal range of the 
species.

WEIGHT and MEASUREMENTS. See Table 8. 


TAXONOMY. Pitohwi kirhocephalus shows more striking geo- 
eraphical variation than any other New Guinea bird and encompasses 
among its subspecies most of the color patterns occurring in the other 
members of the genus. Some races (brunneivertex, jobiensis, and 
meyeri) are fairly uniform brown and resemble P. ferrugineus or I, 
cristatus. Males of other races (meridionalis, nigripectus) have a black 
and maroon pattern like P. dichrous. In addition, most populations, 
including mine, show much individual variation. On the average, my 
specimens are much closer to a topotypical and uniform series of 
brunneiceps collected on the Fly River by the Second Archbold Ex- 
pedition than to the 14 other races with which they were compared. 

The variation among my specimens concerns six features: (1) ‘The 
darkness of the fulvous, somewhat orange color of the breast and belly. 
All Soliabeda birds are darker than all except one of the Karimui and 
Bomai birds. (2) The darkness of the head, which is dark brown in 
most specimens but is nearly black in the Soliabeda specimen labelled 
“b” in ‘Table 8. (3) The distinctness of the hood, which depends upon 
how marked is the contrast between the throat and breast. In the 
Bomai specimen “1”, probably an immature, the throat and breast are 
the same color, and there is no hood. The contrast is slight in four 
Karimui specimens and one from Soliabeda. In three Soliabeda speci- 
mens the throat is nearly as dark as the crown, so that the throat: breast 
contrast forms a very distinct hood. (4) ‘The color of the upper tail, 
which is a rich brown to olive-brown in some specimens but nearly 
black in specimen “b”, while the tail feathers of some other specimens 
are blackish around the shaft. (5) The color of the wings, varying from 
brown to nearly black. (6) ‘he color of the back, which is a slightly 
deeper and richer brown in Soliabeda and Bomai specimens than in 
Karimui specimens, which agree in this respect with Fly River brun- 
neiceps. ‘Vable 8 scores all my specimens and three related populations 
or individuals on the first four of these points. In my specimens there 
is no consistent difference between the sexes in these characters. All 
my specimens have the bill black. 

As summarized in ‘Table 8, most Karimui and Bomai birds are 
somewhat paler below and have less distinct hoods than Fly River 
brunneiceps, while some Soliabeda birds have darker underparts and 
most have darker heads than brunneiceps. In addition, the wings of 
Fly River birds average 3-4 mm shorter. ‘These differences are minor 
in view of the considerable individual and local variation and the 
much more marked differences compared to other races. Males of 
meridionalis, the next race to the east (in southeastern New Guinea), 
are distinct in the really black hood, wings, and tail, while females 
have the head paler than in my series. As seen in Table 8, two males 
from Deva Deva collected by Hamlin, which come the closest of the

available meridionalis specimens to brunneiceps, are approached by 
two of the darkest Soliabeda specimens but still differ in having the 
throat tipped with black. Most specimens of nigripectus (south-west 
ern New Guinea) have the head and tail even blacker than my spect- 
men “b’, and in addition nigripectus males usually have a black 
breast. One aberrant nigripectus male collected by Meek on the 
southern slope of the Snow Mountains (A.M.N.H. No. 656,061), re 
sembles my series and is scored separately in ‘Vable 8. 

BREEDING. Gonads were slightly enlarged in seven males but 
were small in the remaining males and all females. 

DISCUSSION. I found this tropical species common (ca. 2% of 
the local avifauna) at Soliabeda, Bomai, and Karimui but nowhere 
else, not even in Zone | of Mt. Karimui. While it might be found in 
the forest and in dense second-growth at any level from the understory 
to the treetops, sometimes in fruiting trees, it preferred dense thickets 
near the forest edge, where it kept out of sight. A jumble of calls would 
emerge from a thicket, leaves would shake and shapes dart about, 
and finally three or four P. kirhocephalus would emerge and chase 
each other into a nearby thicket. In flight it had a loud, fluttering 
wingbeat, as do P. dichrous and P. nigrescens. Its habits and sometimes 
its voice and appearance resemble P. dichrous, of which it may be 
considered the low-altitude representative, though there is a broad 
overlap. 

VOICE. Loud, liquid, and melodious whistles at medium pitch, 
somewhat harsher than those of P. dichrous. A common element is 
a connected pair of notes, the first note a fourth in pitch below the 
second note. A typical song begins with one such pair, followed a 
second later by two more such pairs in immediate succession, after 
which the song degenerates into an irregular but melodious jumble. 
Often two singers will deliver their jumbles simultaneously from 
adjacent thickets, one starting after the other. his may involve rival 
males singing competitively (countersong). Other instances of one 
bird calling in response to another bird’s call occur frequently. A 
common call note is an upslurred whistle. Elsewhere in New Guinea 
this species sings duets and trios (Diamond and ‘Terborgh, 1968, py 73).

BREEDING. ‘The only specimens with enlarged gonads were the 
1964 Karimui male, collected 12 Aug., and the last male collected at 
Karimui in 1965, on 11 Sept. This may suggest that the breeding sea- 
son is toward the end of the calendar year or is suppressed in dry 
periods. 

DISCUSSION. P. dichrous is the middle bird in an altitudinal 
sequence in genus Pilohwi, occurring between the ranges of P. kirho- 
cephalus and P. nigrescens. It descends regularly to 1,500 ft and reaches 
sea level in a few parts of New Guinea, so that it overlaps the upper 
half of P. kirhocephalus’s range. Its ceiling varies between about 5,000 
and 6,000 ft, and at this ceiling it excludes P. nigrescens, probably 
strictly in undisturbed forest. In the ecologically disturbed forest edge 
at Awande both species were netted at approximately the same alti- 
tude (6,200 ft). The following figures for the contribution of P. dich- 
rous to the avifauna show that it is most numerous in hill forest above 
the range of P. kirhocephalus: Soliabeda, 1,350-2,000 ft, 0.3%; Kari- 
mui, 3,650 ft, 0.7% (P. kirhocephalus present at both Soliabeda and 
Karimui); Mt. Karimui Zone 1, 4,000-4,200 ft, 2% (P. kirhocephalus 
absent at this and higher altitudes); Zone 2, 4,400-4,750 ft, 5.69%; Zone 
3a, 4,750-5,080 ft, 2.6%; Zone 3b, 5,080-5,150 ft, 0.7%; mot observed 
above 5,150 ft. 

Like P. kirhocephalus, P. dichrous may be seen at any height in the 
vegetational column in the forest or in dense second-growth, from the 
understory up to the crowns of tall trees, as solitary individuals or in 
groups of three or four. ‘Terborgh observed it in trees with small fruits. 

VOICE. Loud and mellow whistles at medium pitch, similar to 
those of P. kirhocephalus but with no harsh quality. “wo common 
types of vocalizations are: a rapid series of a half dozen identical up- 
slurs delivered at the rate of 4 per second; and a song consisting of 
whistled notes, upslurs, and downslurs in an interestingly irregular 
and hesitating rhythm, and usually beginning with two notes on the 
same pitch followed by an upslur (Fig. 32).

TAXONOMY. | Both unsexed birds are black and probably males, 
though black females are known (Gilliard and LeCroy, 1970, p. 17). 
As subspecific characters are based mainly on the female, I cannot 
make a racial assignment of this series, which was compared with 
males of nominate nigrescens (Vogelkop), wandamensis (Wandammen 
Peninsula), meeki (Weyland and Snow Mountains), and schistaceus 
(southeastern New Guinea). Males were found to differ in wing length, 
hue (blacker or browner), and depth of color (darker or lighter). As 
shown in Table 9, males from Awande, lying to the east of Mt. Karti- 
mui, have the longest wings, whereas birds from southeastern New 
Guinea, still farther to the east, have the shortest wings. Both Awande 
and Mt. Karimui birds are more black, less brown, than any other 
available for comparison. The possibility of foxing cannot be ex- 
cluded, as all other material was at least 28 years old. The races 
schistaceus and nominate nigrescens are lighter than meeki or wanda- 
mensis. Mt. Karimui birds are comparable to meeki in this respect 
and are darker than four of the five Awande specimens, which are in 
turn darker than schistaceus. On the basis of color Mayr and Gilliard 
assigned their only specimen, a long-winged female from Mt. Hagen,

to buergersi, which was described from the Schraderberg but was un- 
available for comparison and is doubtfully distinct from meeki. More 
females from the Eastern Highlands, including topotypical females 
from the Schraderberg, are necessary to assess the validity of buergersi 
and the status of the Eastern Highlands population, but it is definitely 
closer to meeki than to schistaceus. 

BREEDING. Gonads were small in all specimens. 


DISCUSSION. PP. nigrescens is an uncommon forest species be- 
tween about 5,600 and 8,200 ft, ranging from the understory to about 
35 ft above the ground. The few that I saw were solitary and flew 
with a loud wing beat like P. kirkocephalus and P. dichrous. 

VOICE. An unmusical, buzzy “cher-wee’” repeated two or three 
times in succession. The syllable “cher” is at a lower pitch than “wee”. 
Also, a musical chirp “kyew’’, repeated eight times at 14 sec intervals.

TAXONOMY. Specimens from the Karimui area are closest in 
depth of color to nominate ferrugineus from the Vogelkop and upper 
Fly River, and are also close to birds from the Idenburg River and 
southern slope of the Snow Mountains. ‘The race lewcorhynchus is 
much darker and has a whitish bill; clarws of southeastern New Guinea 
and the lower Fly River is paler; holerythrus of Japen and the Wey- 
land Mountains is darker; and brevipennis of the Aru Islands has the 
black slightly darker. P. f. ferrugineus thus has a checkerboard distribu- 
tion. The bill was black and the iris straw-colored in my specimens. 

BREEDING. Gonads were moderately enlarged in one Soliabeda 
male, greatly enlarged in another, slightly enlarged in one Karimui 
male, and small in other specimens. 

DISCUSSION. ‘To date, this low altitude species has been found 
in the Eastern Highlands only in the Karimui area and at Lake 
Kutubu. Although the number of specimens indicate that it was fairly 
common (1.7% of the local avifauna at Soliabeda and Bomai, ORDO 75 al 
Karimui), I observed it only infrequently, from the understory to 40 
ft above the ground in the forest interior. ‘The altitudinal ranges of 
P. ferrugineus and P. kirhocephalus are coincident in the Karimui 
area (0-3,650 ft). P. ferrugineus is slightly larger, more sluggish in its 
movements, quieter, and more limited to the forest interior, whereas

Pitohui cristatus arthuri Hartert and P. c. kodonophonos Mayr

SPECIMENS EXAMINED. Karimui: 1 ? (6 Aug. 1964). 

WING. 108. 

TAIL. 85. 

EXPOSED CULMEN. 24. 

TAXONOMY. The short wing, tiny gonads, and rufous edges to 
the upperwing coverts suggest that this specimen was an immature. 
‘The bill was dark gray. 

The Karimui specimen is closest to the type and another topotypical 
specimen of arthuri from the Cyclops Mountains and is equally olive 
on the back but differs in being generally slightly darker, distinctly 
darker on the crown, and more rufous on the uppertail. The race 
kodonophonos of southeastern New Guinea, to which Schodde and 
Hitchcock referred a Lake Kutubu specimen, approaches the Karimui 
specimen in the darkness of the crown but is considerably paler below. 
‘The nominate race from the Vogelkop and southern slope of the 
Snow Mountains is darker below, more brown and less olive above. 
When the crest lies flat, P. cristatus is superficially similar to P. fer- 
rugineus but may be distinguished by the rufous uppertail, the dark- 
ened breast band, and the brown instead of straw-colored or whitish 
iris. 

DISCUSSION. Pitohui cristatus is a rare hill forest species known 
in the Eastern Highlands only in the Karimui area and at Lake 
Kutubu. I heard its suspected song a dozen times in the understory at 
Karimui and in hill forest between 2,600 and 4,300 ft. 


VOICE. If the statements of several natives on this matter are 
correct, then P. cristatus is the author of the most extraordinary bird 
song in New Guinea. 

‘The song consists of a long series of identical notes which are 
initially all on the same pitch and at equal time intervals. The pitch 
lies approximately an octave above middle C. One of the two remark- 
able features of the song is its length. One song which I timed and 
which seemed to be of average length lasted 175 sec without interrup- 
tion. As the song proceeds, the notes gradually accelerate and also 
gradually drop in pitch. Thus, the rate of delivery was timed at five 
notes per second at the start of the song, 13 notes per second at the 
end; and the final pitch may be about half an octave below the initial 
pitch. ‘he song ends more or less abruptly in the middle of the series, 
and may then be given again after a pause. 

The other and more remarkable feaure is the unusual, throbbing

quality, suggestive of either the ‘ ‘singing’ sound produced by high- 
voltage transmission lines or else of the sound produced by blowing 
across the narrow mouth of a large open vessel. As a result of this 
quality, the song blends so well into the surroundings and is so 
unlike any other bird song that it does not catch one’s attention, 
least of all if one is listening for bird calls. Although the song is muted 
and not loud, it carries for long distances of up to half a mile that 
are impossible to estimate unless the singer happens to be very close.

‘TAXONOMY. ‘The males are blacker and less brown on the 
breast than nominate “nigropectus’ from the Mambare River and 
Wharton Range or “clara” from Mt. Goliath and the Kubor Moun- 
tains, with the exception of one male from Mt. Tafa (Wharton Range), 
which is equally black. The female has the underparts yellow-olive 
with obscure barring on the throat and breast. A juvenile has the 
back and upperwing coverts rufous. With the description of clara 
(Stresemann and Paludan, 1935, p. 44), topotypical specimens of clara 
from the Weyland Mountains, and southeastern New Guinea birds 
before me, I was unable to detect the differences cited in the descrip- 
tion of clara, which had already been suspected as being synonymous 
with the nominate race by Mayr and Gilliard (1954, p. 354) and Rand 
and Gilliard (1967, p. 438). 


BREEDING. ‘he gonads of all specimens were small. 


DISCUSSION. Eulacestoma nigropectus belongs to a monotypic, 
distinctive, poorly-known, endemic New Guinea genus. ‘Though com- 
mon in southeastern New Guinea, it is uncommon and local in the 
Eastern Highlands at 6,400-8,000 ft, and I met it only on Mt. Karimul. 
It obtains its food from limbs and branches, particularly from the 
broken-off tips of dry dead branches, between the understory and 30 ft 
above the ground. In searching, every few seconds it hops a few inches 
(in dense vegetation) up to four feet (on leafless branches) along a 
limb, frequently leaning over the limb head downwards and nuthatch- 
like to inspect the underside but never hanging upside-down from 
the underside. The ends of twigs bend down under its weight, so that 
it must be weight limited in its choice of feeding station. Occasionally 
it stops to pry, pound, or dig vigorously at a branch, and chips of 
wood and pieces of moss fly as it works. I judge its heavy bill to be 
extremely powerful, having been bitten by it.

WING. 1 9: 96. 

BREEDING. ‘The male, taken in June, had small gonads, but on 
18 Aug. 1964, two nestlings were shown to me at Awande. I was told 
that the kato disappeared from the Okapa area during the wet months 
of Janury, February, and March. Perhaps it breeds in the dry season, 
like many grassland birds, and then undertakes a local migration in 
the wet season. 

DISCUSSION. ‘The Schach Shrike has a peculiar geographical 
range, namely, midmontane grassland of eastern New Guinea as far 
west as Telofolmin but not farther west. There is no obvious reason 
why it should be missing from the midmontane grassland of the Baliem 
Valley of western New Guinea. It is fairly widespread in the Eastern 
Highlands (but is absent at Karimui) and perches on trees and fences 
in grassland, gardens, and villages, quickly flicking its tail as it waits 
to pounce.

TAXONOMY. ‘The wing averages shorter and the weight averages 
lower than in a series from the Wahgi Valley and other parts of New

scribed by Gyldenstolpe is invalid, as pointed out by Sims (U95G,, Po 
422) and by Gilliard and LeCroy (1961, p. 63).

latest one collected, a male taken at Karimui on 15 Aug. 1964, which 
had greatly enlarged testes. 


DISCUSSION. A. maximus was present at all my Eastern High-

lands stations that offered some cleared land, up to 8,500 ft. Its original 
habitat was hill forest and midmontane forest, and one still sees it 
occasionally at an exposed perch on a protruding branch or at the top 
of a dead tree in primary forest. It is far more common, however, in 
settled areas and must have enjoyed a great increase in population 
since the advent of agriculture. It is usually seen soaring without 
flapping, sometimes quite high, or else perched on a branch in tightly 
packed rows of two to six birds, each apparently touching its neighbors. 

VOICE. The call of A. maximus is a pleasant chirp which I can- 
not distinguish from the call of its low-altitude equivalent, A. leuco- 
rhynchus. ‘The rarely heard song, delivered perched from the crown of 
a tall tree, is a prolonged soft jumble including imitations of other 
birds and very similar to the songs of New World mockingbirds 
(Mimidae). Elements include squawks, chirps, and short trills, each 
repeated 2-5 times.

STOMACH CONTENTS. Fruit. 

DISCUSSION. Gilliard and Gyldenstolpe were surprised inde- 
pendently to find large flocks of this lowland species at Nondugl 
(5,200 ft), evidently in the same grove of trees but in different years. 
Specimens taken in April and May were not in breeding condition, 
while those taken in late August and September were entering breeding 
condition and beginning courtship activities. I observed groups of 
four at Goroka on 14 Sept. 1966 and 31 July 1969. According to Bell 
(pers. comm.), this starling breeds in the vicinity of Port Moresby in 
the rainy season (January-May). Perhaps A. cantoroides is undertaking 
postbreeding migrations from the lowlands to the Eastern Highlands 
in increasing numbers. 

VOICE. A clear, sweet downslur.

TAXONOMY. The iridescent color is green in eight females, pur- 
ple in two, and green in two males, blue-green in two, and purple in 
two. Differences in the iridescent color were among the characters used 
to separate a north coast race violaceus, but Mayr and Rand (1937, 
p. 187) and Junge (1939, p. 72) showed that the various colors can 
all be found in a single population (as also true at Karimui) and prob- 
ably change with wear. 

BREEDING. ‘The gonads were small in all specimens. 


DISCUSSION. ‘This lowland species has been found in the Eastern 
Highlands at Lake Kutubu and in the Karimui area (Soliabeda, 
Bomai, and Karimui). At Karimui (3,650 ft) it was fairly common 
(1.2-1.5% of the local avifauna), and its presence there constitutes an 
altitudinal record. It was usually seen in small groups of several (up 
to four) birds, and often in pairs, on conspicuous perches in the tops 
of tall trees (either leafy or dead) at the edge of forest and in second- 
growth. ‘Terborgh found up to 10 M. dwmontii eating small fruits in

TAXONOMY. The bill is either black or else very dull blood-red. 
Because the wing is longer in all females with red bills than in any with 
a black bill, and is also longer in all but two of the red-billed ma_es 
than in any back-billed male, I presume that a black bill is a sign of im- 


maturity. Three of the red-billed males have the underparts buffer 
than the rest. 


BREEDING. The only specimen with enlarged gonads was a red- 
billed male from Okasa. 


DISCUSSION. Oriolus szalayi is present in many ecologically dis- 
turbed areas at the edge of the Eastern Highlands up to about 4,000 
or 5,000 ft and is particularly common at Karimui, but occurs in 
primary forest only at much lower altitudes. Its habitat is the upper- 
story and middlestory of tall trees at the edge of the forest, in second- 
growth, gardens, and in partly cut forest, i.e., wherever it finds perches 
in tall trees adjacent to open spaces. Usually several individuals were 
seen together. 

Plumage convergence of Philemon novaeguineae and O. szalayi is 
discussed on pp. 382-383. 

VOICE. ‘There are three kinds of vocalizations. The commonest is 
the song, a liquid, medium-pitched, fairly loud, run-together series of 
pairs of notes or slurs. ‘he second note is the lower note in the first 
few pairs but is usually the higher note in the last pair (Fig. 33). ‘The 
second vocalization is a call with the same liquid quality, consisting of 
a single note which is initially slurred downward and then upward,

and at the same time undergoes a crescendo and decrescendo, with the 
maximum volume on the lowest pitch (Fig. 33). The third call is a 
single harsh, hoarse, downslurred “chew”.

TAXONOMY. I follow Amadon (1950) in considering the ‘Torrent 
Lark congeneric with the Magpie Lark, Grallina cyanoleuca, of Aus- 
tralia, rather than meriting recognition in the monotypic genus 
Pomareopsis. 

Both unsexed birds were in female plumage. 

DISCUSSION. ‘This is one of the two strictly riparian passerines 
in New Guinea, the other being the less uncommon Monachella muel- 
leriana. Both species require rushing, rocky, mountain torrents, may 
often be found on the same stretch of the same stream, and are 
absent from the flat lowlands. I found G. bruijni in these montane 
streamside habitats from 2,700 to 5,150 ft, and Shaw-Mayer and Bulmer 
observed it at 6,500 ft or higher. A male with small testes was shot 
by one of my assistants at 5,150 ft in forest on the crest of a ridge of 
Mt. Karimui and many hundred feet above the streams on either side 
of the ridge, a habitat in which I never saw G. bruijni myself and 
where my assistant was equally surprised to find it. The bird was 
probably crossing the ridge from one stream to the other. 

G. bruijni is a striking and active bird which alights on boulders in 
torrents and walks (not hops) up the sides of or along the boulders, 
wagging its seemingly loosely-hinged tail from side to side. It spins 
about, turns, and displays like a fantail (Rhipidura). Once while I 
was watching a group of three that had alighted on a large boulder, 
one bird faced the other two, reared up on its legs, raised its head 
and body towards the vertical position, and opened its wings wide to 
show to its partners the striking black and white pattern of the under- 
parts. The sexes differ markedly with respect to this pattern. 


VOICE. ‘The call is a penetrating, buzzy, harsh upslur or upwards- 
inflected squawk, quite different from the sweet, high-pitched note of 
Monachella muelleriana.

STOMACH CONTENTS. Fruit and insects. 

TAXONOMY. ‘The immature male from Karimui has some brown 
striations on the black of the head and back. 


BREEDING. In 1964 at Karimui two of the three sexed adults 
had greatly enlarged gonads. On 13 Aug. 1964 I found a nest contain- 
ing one nestling, located on a horizontal tree branch 40 ft above the 
ground in second-growth forest and constructed of sticks. On the 
same day a native brought in two nestlings from another nest. ‘Testes 
were greatly enlarged in the Bomai male and in one of the three 
Soliabeda males, small in the two others. Evidently breeding is con- 
centrated in the dry season. 


DISCUSSION. ‘The preferred habitat is the crowns of trees bor- 
dering open spaces (never the interior of primary forest), so that this 
butcherbird is much less common in undisturbed forested regions 
than in areas occupied by man. In the areas of primary forest at 
Bomai and Soliabeda small groups of C. cassicus concentrated in river 
gorges at the forest edge. The black and white pattern of the upper- 
parts as it flew across the gorges, and the loud calls echoing back and 
forth across the gorge, made it conspicuous. Other Eastern Highlands 
records are from the Schrader Range, up to 4,500 ft in cultivated 
areas of Kyaka territory (Bulmer), at 3,500 ft in Baityer Valley (N.G. 
B.S. Newsletter, No. 54, p. 2, June 1970), and Lake Kutubu (2,700 ft). 
All these locality records in the Eastern Highlands are rather high for 
C. cassicus, which seldom ranges above 2,000 ft elsewhere in New 
Guinea. 

VOICE. A loud, jumbled bugling and yodeling, which combines 
bell-like notes and liquid and rollicking phrases with hoarse notes, 
eurgles, and musical croaks. The song of the Australian cracticid 
Gymnorhina tibicen is somewhat similar, and the only New Guinea 
song with a comparable volume and combination of different quali- 
ties is that of Cracticus quoyi, which differs in having a more consis- 
tent and organized pattern. Once I heard a particularly long (several 
minutes in duration) and varied jumble, including imitations of other 
birds, in typical C. cassicus habitat (edge of a gorge) and with the 
quality of the C. cassicus song, so that I think it probably came from C.

TAXONOMY. ‘These specimens agree with the widespread New 
Guinea race C. g. guoy? in the short wing and in the breadth of the 
bill at the base as viewed from above. ‘The Australian race spaldingi 
reaches the Aru Islands, and possibly the Digul River and Fly River 
bulge of southern New Guinea (Mees, 1964, p. 32). Other Eastern High- 
lands records are from the Jimmi Valley of the northern watershed 
(Gyldenstolpe) and from Lake Kutubu (Schodde and Hitchcock). 


BREEDING. ‘The gonads were very small in all specimens of C. 
quoyt, whereas C. cassicus was breeding at this time (August 1964, 
July-August 1965). 

DISCUSSION. C. quoyi differs ecologically from C. cassicus in 
being (1) found in the forest interior, (2) solitary, (3) much less com- 
mon in most parts of New Guinea, and in (4) spending much of its 
time in the lower story. ‘he latter difference is illustrated by netting 
results: C. cassicus was never netted, whereas four of the 13 specimens 
of C. quoyi were collected with nets. 

C. quoyi was more common and conspicuous at Karimui than at 
any other locality in New Guinea I have visited. Occasionally an in- 
dividual would come out of the forest, perch up to 20 ft above the 
ground in a roadside tree, and give its distinctive call, to be answered 
by a couple of other individuals in the distance. More often it skulked 
and was glimpsed only briefly as it flew through the undergrowth a 
few feet above the ground. On Mt. Karimui it was heard occasionally 
in Zones | and 2 between 4,030 and 4,370 ft; this probably represents 
its altitudinal ceiling. 

VOICE. The call and the song are equally loud, ringing, and 
distinctive and carry considerable distances. ‘The call consists of four 
notes within a time span of | sec (Fig. 34). The first of these four 
notes is a hoarse upslur, while the second, third, and fourth notes are 
ringing. Ihe time interval between the first and second notes is twice 
as long as the other intervals. ‘The second and fourth notes are on the 
same pitch, and near the pitch of the first note, while the third is a 
fourth lower in pitch. ‘he bold and ringing song has a striking rhythm 


301 


SPECIES ACCOUNTS 


and interval pattern (Fig. 34). It begins with three notes in a dotted 
rhythm, followed by a series of three to six three-note phrases. The 
second note of all the phrases is on the same pitch, and the third note 
is always on another pitch a third below the second note. The first note 
of the phrase is alternately a third and a fourth higher than the second 
note. ‘he time interval between the first and second note equals that 
between the second and third note when the pitch interval is a third, 
and is twice as long when the pitch interval is a fourth. The whole 
song lasts 5 sec. While these descriptions may sound complicated, both 
the call and the song are in practice “catchy”, unmistakable, and 
consistent, and may be made clearer by Figure 34. An additional call 
consists of pairs or longer series of hoarse, harsh, and more or less 
musical upslurred croaks.

TAXONOMY. The specimens all belong to the resident New 
Guinea race carbonarius, not to the Australian race (possibly a separate 
species) bracteatus, which winters and possibly may breed (Rand, 
1938c) in southern New Guinea. D. h. bracteatus has a green instead 
of purple gloss and has less of the bill covered by feathering at the 
base than does carbonarius. My measurements of the exposed culmen 
give: carbonarius (Fly River and Idenburg River, collected by the 
Second and the Third Archbold Expeditions), $ 22-25, 9, 20-22; 
bracteatus (Fly River, collected by the Second Archbold Expedition,

BREEDING. One Bomai female had enlarged ovaries, but gonads 
in all other specimens were small. 

DISCUSSION. In the Eastern Highlands the Spangled Drongo has 
been recorded from the Karimui area (to 3,650 ft), and from 3,500 ft 
in the Batyer Valley (N.G.B.S. Newsletter, No. 54, p. 2, June 1970); 
where it 1s above its normal altitudinal range, and also at Lake Kutubu 
(2,450 ft). In habits it was solitary and to be found in the middlestory 
of trees at the edge of the forest and in second-growth but not (or 
rarely) in the forest interior. It held its perches for relatively long 
times, frequently flaring its tail and flicking the tail with each call. 

VOICE. ‘The call consists typically of three ringing disyllabic notes 
‘“‘k-sing”’, the second and third notes on the same pitch and the first on 
a higher pitch. ‘The first syllable is very brief, virtually a grace note to 
the second syllable, and has a sharp and explosive attack. The longer 
second syllable is more nasal. Each note lasts not quite 1% sec. This 
call is surprisingly similar to the usual call of the parrot Geoffroyus 
geoffroyi and sometimes not safely distinguishable from it. Other calls 
are a rapid series of nasal notes on the same pitch, and notes with a 
strange quality as a siren or creaking door.

BREEDING. Gonads of all specimens were small, often very small. 


DISCUSSION. Chaetorhynchus papuensis, a monotypic genus en- 
demic to New Guinea, is a solitary and inconspicuous but ubiquitous 
species confined to the interior of hill forest. It reached its maximum 
abundance in Zone | of Mt. Karimui (4,000-4,200 ft, 3.59% of the local 
avifauna). At Soliabeda (2,000 ft), which is probably at the lower limit 
of its altitudinal range, it was quite uncommon, and its ceiling on 
Mt. Karimui was around 4,800 ft. There is no tendency for individuals 
to stray above the ceiling in this species. As usual, only or mainly males 
are present near the ceiling, while the lowest stations (Soliabeda and 
Bomai) had mainly females and immatures. I generally found C. 
papuensis perched stationary and upright, like a large flycatcher, on a 
horizontal branch in the understory or up to 40 ft above the ground. 
On one occasion I saw the usually-concealed white scapular patch on 
a bird in the field, suggesting that it may be used for display or 
recognition purposes. 

VOICE. Whe calls are a strong, explosive “pik” or “peep, given 
either once or five to seven times in rapid-fire succession; and a down- 
slurred, whistled “‘pi-yew’’. ‘The song is a loud, prolonged jumble.

age, but other larger series taken by other collectors have suggested 
that it is a matter of individual variation.

PARADISAFIDAE: BIRDS OF PARADISE 
Generic Revision of the Paradisaeidae 


The family Paradisaeidae consists of 25 species or superspecies. Vir- 
tually all recent classifications, e.g., the ones by Mayr (1962) in Peters’ 
Check-list, Vol. 15, and in the book by Gilliard (1969), distribute these 
25 species and superspecies among 20 (sometimes 21) genera, of which 
11 are monotypic in the strictest sense, six are monotypic in the sense 
of consisting of a single superspecies, and only three (15% of the 
genera) contain more than a single species or superspecies. While this 
degree of generic splitting and this low species-to-genus ratio (1.25) is 
unparalleled among bird families of comparable size, there are even 
more finely split alternative classifications of the Paradisaeidae, such 
as that of Iredale (1948), who lists many subspecies and hybrids as 
separate species and genera and thereby arrives at 40 genera. 

These classifications deprive the genus taxon of meaning. While the 
species taxon corresponds to a biological reality, namely, a group of 
interbreeding populations, the genus taxon and other higher categories 
are arbitrary groupings erected for taxonomic convenience in indicat- 
ing relationships. ‘The higher categories are based on a_ biological 
reality insofar as the distances between species of a phylogenetic tree 
are not equal. However, these interspecies distances vary continuously, 
while the number of levels of higher categories is finite and small. 
Hence delineation of higher categories always involves some degree of 
arbitrariness and is dictated by practical considerations (see Mayr, 
1942, pp. 275-291, especially his Fig. 29, for further discussion). A 
monotypic genus tells nothing about the relationship of the species in 
it, and the adding of the genus name to the species name conveys no 
new information. A practical justification for a monotypic genus 
nevertheless arises in two cases: if the affinities of a species are un- 
known; or if a species differs much more markedly in several inde- 
pendent characters from its relatives than its relatives differ from each 
other. 

On neither of these two grounds is the recognition of many mono- 
typic genera among the Paradisaeidae justified. ‘There are only three 
species in the family about whose affinities not enough is known to 
place them near some other species. Except in respect to one class of 
characters (the ornamental plumes of adult males), most paradisaeid 
species fall into compact groups. Females and immature males of dif- 
ferent “genera” are often so similar that even experts such as Strese- 
mann have misidentified specimens as to “genus” (cf. Lophorina 
superba pseudoparotia, p. 312, and the nest attributed to Loria loriae, 
p. 000). Intergeneric hybrids are known from 10 of the 20 ‘general’. 

The historical reason for the high degree of generic splitting in the 
Paradisaeidae has been the ornamental feathers of adult males, which 
are more bizarre and diverse than in any other family. ‘hese orna- 


305 


SPECIES ACCOUNTS 


ments include wire-like feathers growing out of the tail or head, 
central rectrices several times as long as the rest of the bird, scalloped 
occipital plumes twice as long as the rest of the bird, wattles, dorsal 
capes, breast shields, and pectoral fans. However, these ornaments are 
poor generic characters, because species whose adult males appear at 
first glance so drastically dissimilar as to suggest they belong to dif- 
ferent families may prove to be closely related in most other respects 
(e.g., Crcinnurus regius and Diphyllodes magnificus; Lophorina superba 
and the Parotia superspecies). Marked variation in these ornaments 
occurs even within the same superspecies and was used by Iredale to 
place members of the same superspecies in different genera. For in- 
stance, Diphyllodes respublica has a bare crown of naked blue skin, 
D. magnificus does not; Parotia wahnesi has a tail twice as long as the 
other three members of its superspecies; and Paradigalla carunculata 
has a tail three times as long as that of Paradigalla brevicauda. Adult 
male displays can be equally divergent. For instance, Paradisaea 
rudolphi and P. guilielmi display upside-down, which the other Para- 
disaea forms do infrequently or never; Parotia constructs dance areas 
on the ground, while the closely related Lophorina displays in trees; 
and Diphyllodes similarly constructs ground courts, unlike the arbo- 
really displaying but related Cicinnurus. 

A generic classification of the Paradisaeidae that indicated relation- 
ships more effectively than the oversplit one in current use would be 
desirable for several reasons. No New Guinea bird family offers such 
clear and numerous examples of intermediate stages in speciation. As 
noted by Bock (1963, p. 100), the Paradisaeidae “‘could provide an 
excellent example of adaptive radiation in feeding habits’, but this 
has been “one of the least discussed features of the birds of para- 
dise. .. .” They could also illustrate clearly the types of niche differ- 
ences which make coexistence among closely related species possible. 
The parallel geographic variation in females of Lophorina superba 
and the Parotia superspecies is remarkable but has never been dis- 
cussed. ‘The acceptance of predominantly monotypic genera has been 
an important reason why the illuminating examples provided by birds 
of paradise with respect to these ecological and evolutionary questions 
of general interest have not received more attention. A prerequisite 
for exploitation of the Paradisaeidae in this sense is a better under- 
standing of relationships among paradisaeid species, as expressed in 
generic grouping. 

An adequate generic classification should be broadly based rather 
than relying on single characters. In the following tentative revision 
I have taken into account the following types of characters: female 
plumage; similarities rather than differences in adult male plumage; 
the anatomical studies of Bock (1963) and Stonor (1938); altitudinal 
range, voice, and observations of behavior and diet derived from my 
field experience of 17 of the 20 currently recognized genera; geo- 


306 


SPECIES ACCOUNTS 


graphical distribution; hybridization; and displays. Preliminary efforts 
also to draw conclusions from eggs were not productive because the 
variation within the whole family seemed not much greater than the 
variation within one genus or superspecies. The point of considering 
altitudinal range is that, in other New. Guinea families, species with 
mutually exclusive altitudinal ranges and similar habits almost always 
prove to be closely related and congeneric (p. 27). Jt is explicitly 
assumed that no differences in male ornamental plumage, no matter 
how exaggerated, should disqualify two birds of paradise from being 
considered congeneric if this is the conclusion indicated by other kinds 
of evidence. In this family in which morphological divergence has 
spectacularly outpaced the development of reproductive isolation, it 
is important to realize that one must accept genera exhibiting a much 
greater range of morphological variation among adult males than in 
morphologically more conservative families. 

The starting point for this revision is Bock’s (1963) discovery that 
the Paradisaeidae can be divided into two or three groups by anatom1- 
cal criteria: the subfamily Cnemophilinae, consisting of the “genera” 
Cnemophilus, Loria, and Loboparadisea; the subfamily Paradisaeinae, 
with 16 of the 17 remaining ‘genera’; and the monotypic genus Mac- 
gregoria, which appears in several respects intermediate. I consider in 
turn the following problems: (1) The relation between Manucodia 
and Phonygammus. (2) ‘The relation between Epimachus and Drepa- 
nornis. (3) The relation between Cicinnurus and Diphyllodes. (4) ‘The 
relations between Lophorina, Parotia, and Ptiloris. (5) ‘The affinities 
of groups 3 and 4 to each other, and of Astrapia, Pteridophora, and 
Seleucidis. (6) ‘The affinities of the remaining groups of Paradisaeinae 
(Paradisaea, Paradigalla, Semioptera, Lycocorax, and Macgregoria). 
(7) Evaluation of genera of Paradisaeinae. (8) ‘The relations among the

1. Relation between Manucodia and Phonygammus. 


The birds of paradise, popularly known as manucodes, comprise four 
closely related species or superspecies, currently called M. chalybatus 
and M. comri (probably constituting a superspecies), Manucodia ater, 
M. jobiensis, and Phonygammus keraudrenii. Apparently all are 
monogamous and form stable pair bonds, unlike most other birds of 
paradise. Correlated with this, no hybrids involving these species are 
known. All are medium-sized (wing 160-240 mm), nearly uniform 
glossy black, and sexually monomorphic, and have heavy, crow-like 
bills. All live in the middle- and upperstories of the forest. Probably 
all have a peculiarity called a convoluted trachea, namely, a loop of 
windpipe in adults extending onto the breast between the skin and 
muscles, although the erroneous assumption is sometimes made that 
this is peculiar to keraudrenit. Definitive information about the 
presence of a convoluted trachea seems to be unavailable for the semi-

species comrii, but I have dissected specimens of chalybatus, jobiensis, 
and keraudreni with convoluted tracheas, and van Oort (1909, p. 
105) published a drawing of the convoluted trachea of ater. ‘The 
description of the call of jobiensis by Ogilvie-Grant (1915, p. 9) is 
similar to the calls I have heard from keraudrenii, and Rand (1938d, 
p- 1) suggested similarity of the call of jobiensis to that of ater. 

In the areas where I have collected, there has been a_ three-fold 
altitudinal sequence, with keraudreni at the highest elevations, 
chalybatus at medium elevations, and ater and jobiensis sharing the 
lowest elevations. Among the many normally montane species of New 
Guinea birds that descend to sea level at the mouth of the Fly River 
are chalybatus and keraudrenii. ‘The five forms differ in the adult 
mainly in some details of the ornamentation, which is little developed 
in manucodes compared to most other paradisaeids. Perhaps the most 
distinct form is comrii, which has twisted central tail feathers, a raised 
mat of feathers on the crown, and very curled and crinkled feathering 
of the neck and underparts. Crinkling is present but less marked in 
chalybatus and jobiensis, which are difficult to distinguish even as. 
adults. In keraudreni there are elongated head and neck feathers and 
a tuft of feathers on the crown whose length varies subspecifically, 
being longest in the races hunsteint and in jamesiz of the Eastern 
Highlands and shortest in the race neumanni and the nominate race. 
‘The breast feathers of ater are slightly curled and pointed. Immatures 
and subadults of all species are very similar and have occasionally 
been misidentified. “The most similar species are chalybatus and its 
lowiand sibiing jobiensis, which appears to be the product of a recent 
speciation and is still largely confined to the north coast of New 
Guinea but has had its whole geographical range reinvaded by chaly- 
batus, the altitudinal ranges of the two species being mutually ex- 
clusive. 

The monotypic genus Phonygammus has long been accepted for the 
species keraudreni. No other currently used paradisaeid genus seems 
to me so devoid of justification. ‘he manucodes form a compact group 
very similar to each other and distinct from other birds of paradise, 
and constitute an ideal genus. The head tufts of Manucodia keraudreni 
are greatly reduced in some subspecies, could not be considered a 
character of generic value even if long and constant, and are much less 
distinctive than the ornamental feathering of the semispecies M. comyrit. 
Even such keen observers of birds of paradise as my Daribi native 
assistants used the same name, “pagonabo”, for M. keraudreni and 
the other species of manucode in their native valley, M. chalybatus. 


2, Epimachus and Drepanornis. 


Eleven species or superspecies of the Paradisaeinae (10 currently 
recognized genera) constitute a related group eight of whose members 


308 


SPECIES ACCOUNTS 


hybridize with at least one and sometimes with as many as four other 
members of this group. The females are all brown dorsally, with bars 
or else markings derived from bars ventrally. The males share to vary- 
ing degrees the features of a glossy black coloration, a soft velvet 
texture to the dorsal feathers due to a distinctive feather structure, and 
a green iridescent crown. This group consists of the “genera” Epi- 
machus, Drepanornis, Lophorina, Parotia, Ptiloris, Diphyllodes, Cicin- 
nurus, Astrapia, Pteridophora, and Seleucidis. Within this association 
the most specialized and strikingly distinct forms as regards a func- 
tionally significant character are the related genera Epimachus and 
Drepanornis. 

The genus Epimachus consists of two similar species, £. fastosus of 
western New Guinea and E. meyeri of eastern New Guinea. ‘They are 
sympatric in most of central New Guinea with mutually exclusive 
altitudinal ranges (E. fastosus, ca. 4,500-7,500 ft; E. meyert, ca. 7,500- 
9,500 ft) and are probably products of a recent speciation and rein- 
vasion according to the mechanism discussed on p. 34. ‘The genus 
Drepanornis consists of two similar species whose geographical ranges 
are still allopatric and which may therefore be considered a super- 
species: D. bruijnii of the western New Guinea lowlands north of the 
Central Range between long. 136 and 141°E, and D. albertisii, which 
lives in much of New Guinea except for the area inhabited by D. 
bruijnit and ranges from 2,000 ft up to a ceiling varying geographically 
between ca. 5,000 and 7,000 ft. ‘Che most distinctive features of all 
four forms is the long and slender sickle-shaped bill (culmen from base 
65-80 mm), a feature possessed by no other paradisaeid. Epimachus 
and Drepanornis are superficially similar and have always been placed 
next to each other in classifications. 

The similarity appears to be more than superficial. Bock (1963, 
p. 101) stated that the skulls of the two genera were virtually identical 
except for the lacrymal being larger in Epimachus. Stonor (1938, pp. 
468-472) noted that details of the feather tracts were similar, e.g., the 
extreme narrowing of the terminal portion of the ventral tract. The 
four forms are of similar sizes (wing 150-210 mm) and share the follow- 
ing features of plumage, several of which distinguish them from such 
related genera as Lophorina, Parotia, and Astrapia; a solid gray-brown 
(E. meyeri and both Drepanornis forms) or black (E. fastosus) breast 
in adult males; similar lateral tufts and pectoral tufts in adult males 
(cf. Stonor, 1938), but not the distinct breast shields of Lophorina or 
Parotia or the different shield of Astrapia; a solid velvet-black chin in 
adult males; a brown unstriped head in Epimachus males and in both 
sexes of Drepanornis, unlike the black striped head of Lophorina and 
Parotia; and barred underparts in the females. The most marked 
plumage differences between Drepanornis and Epimachus concern the 
much longer tail of Epimachus, and the upperparts of adult males, 


309 


SPECIES ACCOUNTS 


which are brown in Drepanornis (as in females of all four forms) but 
velvet-black on the back and iridescent blue-green on the crown in 
Epimachus, as in Lophorina, Parotia, and Astrapia. 

Little is known about the habits of D. bruijnii, but the other three 
forms live in the forest crown and use their long bills to probe for 
insects and pick berries. The stomach contents given on labels of 
Shaw-Mayer’s specimens of these three forms in the American Museum 
of Natural History include grasshoppers, other insects, berries, and 
fruit; the stomach contents of E. meyeri which I dissected included 
insects, grubs, and fruit; and van Heurn found fruit and seeds in the 
stomach contents of D. bruijnii (Hartert, 1932). ‘The two genera to- 
gether may provide a threefold altitudinal sequence, D. albertisii-E. 
fastosus-E. meyeri. On Mt. Karimui I found that the range of D. 
albertistt was wholly below that of E. fastosus, and this is also sug- 
gested by Stein’s (1936) records for the Weyland Mountains, with the 
transition altitude around 4,200-5,000 ft. In southeastern New Guinea, 
where the middle-altitude E. fastosus is absent and only the high- 
altitude E. meyert remains, and on the Huon Peninsula, where both 
species of Epimachus are absent, labels of specimens taken by Anthony 
and Shaw-Mayer show D. albertisii as high as 7,000 ft, suggesting that 
it may range higher in the absence of competition from £. fastosus. 

Since the four sicklebills are closer to each other than to other 
paradisaeids and share the most specialized bills of the family, they 
form a natural genus, with the name Epimachus having priority and 
Drepanornis available as a subgeneric name. Presumably the common 
ancestor speciated to form the two lines or subgenera, with each line 
speciating again to yield the present four forms. 


3. Relation between Cicinnurus and Diphyllodes. 


The genus Diphyllodes consists of a superspecies, D. magnificus 
on the New Guinea mainland and D. respublica on the islands of 
Waigeu and Batanta. Cicinnurus is monotypic (C. regius). At first 
glance one is struck by dissimilarities in the adult males, Cicinnurus 
being scarlet and white, Diphyllodes green, velvet, red, and yellow. ‘The 
displays are also different, Diphyllodes clearing courts on the ground, 
Cicinnurus displaying in the trees. However, the two genera are similar 
in most other respects and have been placed next to each other in 
recent classifications. ‘The affinity is attested by the fact that more 
hybrid specimens of the D. magnificus x C. regius cross are known 
than for any other paradisaeid hybridization. 

The morphological resemblances include the following. Adult males 
of both genera have two slender, greatly elongated central rectrices, 
which cross at the base (as in no other paradisaeid), are curved at the 
tip, and have barbs restricted to one side of the shat. Whe feather 
tracts are similar (Stonor, 1938). The skulls are very similar in most 
respects (Bock, 1963). In both genera the back of the adult male has 


310 


SPECIES ACCOUNTS 


scarlet areas, and lacks black areas, whereas the other related para- 
disaeids in which the female also has barred underparts (Lophorina, 
Parotia, Astrapia, etc.) have the back largely velvet-black in the adult 
male and lack scarlet areas. The females are similar generally, and 
particularly in having brown unstriped heads, unlike the blacker 
striped heads of Lophorina, Parotia, and Ptiloris. Cicinnurus regius 
is closer to D. respublica than to D. magnificus, e.g., in size (wing Ca. 
110 mm in D. magnificus, 95 mm in the other two species), in the ven- 
tral coloration of the female (the barring is closer and the ground color 
less ochraceous in D. magnificus than in the other two species), and in 
the red dorsal coloration of the male (least extensive and dullest in 
D. magnificus). 

Both Cicinnurus and Diphyllodes eat mainly fruit and have rela- 
tively short bills. Both spend much time in the lowerstory and are 
regularly trapped in mistnets but also range up to the forest crown, 
I have not heard the call of Cicinnurus regius adult males, but the 
description of it by Gilliard (1969) is similar in pattern to the calls I 
heard from D. magnificus adult males, a series of loud, harsh notes on 
the same pitch. Most of the altitudinal range of D. magnificus (5,000 ft 
down to the lower hill slopes, adult males generally uncommon below 
2,000 ft) lies above that of Cicinnurus regius (the flat lowlands up to 
about 2,000 ft in most areas). ‘The ecological differences between these 
two similar species in the zone of altitudinal overlap are probably 
related in large part to size, since D. magnificus is 60°% heavier than 
G. neous: 

Consideration of the taxonomic status of Diphyllodes and Cicinnurus 
is postponed until the remaining species of Paradisaeidae have been 
discussed. 


4. Relations between Lophorina, Parotia, and Ptiloris. 


The genus Lophorina is monotypic (L. superba), while Parotia con- 
sists of a superspecies (P. sefilata, P. carolae, P. lawesi, and P. wahnest) 
and Ptiloris also consists of a superspecies (P. magnificus, P. victoriae, 
P. paradiseus). Parotia is distinct in that adult males clear display 
courts on the ground and have six wire-like plumes on the head. ‘Chere 
are also some differences in the bills and hence in the feeding habits 
and skulls of these three groups. Parotia has a bill similar to that of 
Cicinnurus or Diphyllodes and feeds largely on fruit. Lophorina has 
a more slender bill and takes not only fruit but also beetles, grass- 
hoppers, and other insects. The bill is somewhat longer in Ptiloris 
(more so in P. magnificus than in the other two semispecies) and is 
used to obtain insects from bark and crevices as well as to take fruit. 
In plumage, however, both in the female and in some ornaments of 
the adult males, these three groups are extremely similar. So detailed 
is the resemblance that Stresemann (1923, p. 31) initially listed the 
Lophorina females collected by Burgers on the Hunsteinspitze as 


oll 


SPECIES ACCOUNTS 


Parotia carolae, and only 10 years later did he recognize them as a 
(thinly differentiated) new race of Lophorina superba, which he ac- 
cordingly named L. s. pseudoparotia. Hybrids are known between 
Lophorina and Parotia, and between Lophorina and Ptiloris. 

The plumages of the adult males are basically similar except for 
the wire-like plumes of Parotia. The coloration is mainly black, with 
glosses of various shades. The dorsal feathers have a soft, velvet-like 
texture and, in Lophorina, are laterally prolonged into a cape. The 
crown is iridescent blue-green (in Parotia this is true only distally). 
All three species or superspecies possess a distinctive ventral ornament 
shared by no other paradisaeid, an iridescent blue-green breast shield of 
flattened, stiff feathers which have black central dots in some popula- 
tions of each group (e.g., the dots are present in Parotia, Ptiloris 
magnificus, and the Lophorina superba races from the Central Range, 
but they are absent in Ptiloris victoriae, Ptiloris paradiseus, and the 
races Lophorina s. superba and L. s. niedda of the Vogelkop and 
Wandammen Peninsula). The shield is markedly prolonged laterally 
in Lophorina and slightly in two of the three Ptiloris semispecies. ‘The 
iridescence of the shield varies from green to purplish among the 
Parotia semispecies. The feather tracts in the three “genera” are 
similar (Stonor, 1938). 

The females share a basic color pattern (brown back, blackish head 
and moustache with whitish superciliary and gape stripes, close black 
and white ventral barring on an ochraceous background), and similar 
types of marked geographic variation are encountered in the three 
groups. ‘The upperparts vary from rufous (Ptiloris magnificus, Parotia 
wahnest and P. lawest) to olive-brown (Ptiloris paradiseus and P. 
victoriae, Parotia carolae, Lophorina superba latipennis). Rufous 
edges are present on the remiges of Ptiloris magnificus, Parotia wah- 
nest and P. carolae, and the Lophorina races of the Central Range; 
reduced in Ptiloris paradiseus, Ptiloris victoriae and Parotia lawes?; 
and nearly absent in Parotia sefilata and the Lophorina races superba 
and niedda. The underparts have a pronounced ochraceous wash in 
Ptiloris victoriae and Parotia lawesi and P. wahnesi, less of a wash in 
Ptiloris paradiseus, Parotia carolae, and Lophorina s. feminina, still 
less of a wash in Parotia sefilata and Lophorina s. minor, and the 
ground color is virtually white in Ptiloris magnificus. ‘The light super- 
ciliary stripe is conspicuous in Ptiloris, Parotia carolae, and the 
Lophorina races from the Snow Mountains (feminina) eastwards; re- 
duced to a narrow streak posterior to the eye in Parotia wahnesi; and 
completely or nearly absent in Parotia sefilata and P. lawesi and the 
Lophorina races L. s. niedda and L. s. superba. The crown is black in 
the Parotia semispecies sefilata, lawesi, and wahnesi and in the 
Lophorina races L. s. superba and L. s. niedda, brown in Ptiloris 
magnificus, Parotia carolae, and Lophorina s. feminina. In the area 
immediately below the eye the light gape stripe is absent in the 


312 


SPECIES ACCOUNTS 


Lophorina races L. s. superba and L. s. niedda, while the dark 
moustache is conspicuous in the Parotia semispecies sefilata, lawesi, 
and carolae, reduced in Ptiloris magnificus and Parotia wahnesi, vir- 
tually absent in Ptiloris paradiseus, and entirely absent in the 
Lophorina races of the Central Range. The markings of the under- 
parts are bars in Parotia, Lophorina, and Ptiloris magnificus, crescent- 
shaped in Ptiloris paradiseus, and reduced to sparse dots in P. victoriae. 

One of the most remarkable and overlooked features of this geo- 
eraphic variation of the females is that it runs parallel in some popula- 
tions of Parotia and Lophorina. Thus, Parotia sefilata is confined to 
the Vogelkop and Wandammen Peninsula. The Lophorina races in 
this region (nominate superba on the Vogelkop, niedda on the Wan- 
dammen Peninsula) resemble a small version of this Parotia semi- 
species in the black head, dark back, reduction of the rufous edges 
of the remiges, and obliteration of the superciliary stripe, and differ 
only in the absence of the gape stripe. In the Snow Mountains the 
crown is brown and the superciliary conspicuous both in the Parotta 
semispecies (carolae, the one for which Stresemann and van Heurn 
independently mistook Lophorina) and the Lophorina race (feminina), 
and the olive back, the rufous edges of the remiges, and the color of 
the underparts match well. In eastern New Guinea the species deviate, 
since the underparts are much less ochraceous, and the superciliary is 
much more conspicuous, in Lophorina than in Parotia (P. lawesi and 
P. wahnes). 

‘The altitudinal ranges of Lophorina and Parotia largely coincide 
with each other (usually ca. 3,500-6,500 ft), and largely exclude that 
of Ptiloris magnificus (sea level to ca. 3,000 or 4,000 ft). Ecological 
segregation between Parotia and Lophorina probably depends on 
Parotia’s greater size (nearly twice as heavy as Lophorina) and 
Lophorina’s longer bill and greater consumption of insects. 


5, Affinities of groups 3 and 4, and of Astrapia, Pteridophora, and 
Seleucidis. 


While Cicinnurus and Diphyllodes are particularly close, and Ptiloris, 
Lophorina, and Parotia are very close, these two groups are also re- 
lated to each other. ‘This is illustrated by the basically similar pattern 
of the females (brown dorsally, barred underparts; remiges edged 
rufous in Diphyllodes respublica and in Cicinnurus but not in D. 
magnificus) and by the resemblances between the skull and bill of 
Parotia on the one hand and of Diphyllodes and Cicinnurus on the 
other (Bock, 1963). Field observations suggest that Diphyllodes magnifi- 
cus and Lophorina are close. Adult males of these two common species 
have mutually exclusive altitudinal ranges: on Mt. Karimui I found 
that the lowest adult males of Lophorina appeared about 35 ft above 
the highest males of Diphyllodes. While Lophorina females and im- 
mature males penetrated 1,000 ft into the range of Diphyllodes, the 


313 


SPECIES ACCOUNTS 


abundances of the two species varied complementarily in the overlap 
zone so that the sum of their abundances remained relatively constant. 
The calls of adult males are quite similar. The species differ only by 
13% in weight, and both spend much time in the understory but also 
range into the forest crown. Hybrids are known. 

There are three other birds of paradise whose relationship to the 
Lophorina and Cicinnurus groups is indicated by female plumage, 
and whose relationship to the Lophorina group is further indicated 
by male plumage. These are the Astrapia superspecies, Pteridophora 
alberti, and Seleucidis me’anoleuca: 

Astrapia consists of five midmontane and high-altitude semispecies 
(A. nigra, A. splendissima, A. mayeri, A. stephaniae, and A. rothschildt). 
The adult male plumage conforms closely to the Lophorina-Parotia- 
Ptiloris type (black with various glosses, the crown iridescent blue- 
green, the back with a soft velvet-like texture). The central rectrices 
of the adult male are greatly elongated as in Epimachus and (less 
markedly) in Parotia wahnesi, and the feathers of the nape are 
lengthened to varying degrees in different subspecies. However, Astra- 
pia lacks specially modified ornamental feathers. ‘The females are 
brown dorsally, barred ventrally, and brownish-black on the head and 
upper breast. Most of the altitudinal range of Astrapia is shared by 
the smaller Pteridophora, which weighs only half as much, and by 
the sicklebilled Epimachus meyert. ‘The lower part of Astrapia’s range 
is shared with Lophorina and Parotia. Hybrids with Epimachus 
fastosus are known. Although Astrapia would be regarded as wildly 
aberrant in any other family, by the standards of the Paradisaeidae 
it must be considered as having few distinctive features of significance. 
The long tail of the adult male cannot be regarded as a good generic 
trait within this family, because of the marked variation in tail length 
among the semispecies of Parotia or Paradigalla and between the re- 
lated Epimachus and Drepanornis. Astrapia has generally been placed 
next to Epimachus in classifications because of the long tail, but 
lengthened tails have apparently been acquired independently in four 
groups (Parotia, Paradigalla, Astrapia, Epimachus) among the 11 spe- 
cies or superspecies of the brown-female complex (listed on p. 309). 
There is no other reason to suspect that Astrapia is closer to Epimachus 
than to other members of the complex. 

The monotypic genus Pteridophora (P. alberti) has particularly 
bizarre ornamental feathers in the adult male, a pair of long and 
scalloped occipital plumes. As in Lophorina, the upperparts are black 
with a soft velvet texture, and the feathers of the upper back are 
lengthened into a Lophorina-like cape, but the lower breast and belly 
differ from Lophorina in being yellowish. Females are brown dorsally, 
lack stripes on the head (cf. Cicinnurus), and are whitish ventrally 
with dark curved bars similar to those of Ptiloris paradiseus females 
but less deeply curved. The weight of Pieridophora is approximately 


314 


SPECIES ACCOUNTS 


the same as that of Lophorina. The altitudinal range is almost entirely 
above that of Lophorina, both in my experience and in that of Gilliard 
(1969). The only competing species of Paradisaeinae at these altitudes 
are the heavier Astrapia and the sicklebilled Epimachus. As gauged 
from stomach contents, the diet is largely fruit, with seeds reported 
once. Pieridophora may be thought of as the high altitude member of 
the four-species altitudinal sequence Pteridophora-Lophorina-Diphyl- 
lodes-Cicinnurus. ‘The bill and skull are much as in Crcimnurus or 
Parotia (Bock, 1963). Pteridophora may be less close to the Lophorina 
group, particularly in the colored underparts of the male, than is 
Astrapia, but it is still a relatively undistinctive form (apart from the 
occipital plumes). 

The monotypic genus Selewcidis (S$. melanoleuca) lives in lowland 
swamp forest, has an elongated bill, is medium-sized (160-200 g), and 
feeds on seeds, fruit, insects, and nectar. ‘The female plumage conforms 
extremely closely to the Lophorina-Parotia-Ptiloris pattern: the back 
and wings are rufous (cf. Ptiloris magnificus, Parotia wahnesi), the 
head solid black (cf. Lophorina s. superba and L. s. niedda), the under- 
parts pale ochraceous with close barring (as close as in Ptiloris magni- 
ficus and Diphyllodes, somewhat closer than in Lophorina or Parotia). 
The male shares with Lophcrina and its allies the glossy black upper- 
parts with a soft velvet texture. The breast shields of Seleucidis, 
Ptiloris, Lophorina, and Parotia males form a series: all feathers are 
stiff and flattened in Lophorina and Parotia, fewer are stiff and flat- 
tened in Ptiloris magnificus, stull fewer in Ptiloris paradiseus, fewer 
again in Ptiloris victoriae, and none in Seleucidis, in which the whole 
shield is composed of soft feathers. The male of Selewcidis differs 
from Lophorina in its yellow belly which fades to white postmortem 
and in its lengthened white flank plumes with 12 wire-like feathers, 
but these features are paralleled by the yellowish belly of Pteridophora 
and the lengthened purple flank plumes of Ptiloris magnificus. Hybrids 
with Ptiloris and Paradisaea are known. The bill is somewhat more 
specialized than in other forms of groups 3, 4 and 5 but is not nearly 
so specialized as in Epimachus and is quite like that of Ptiloris, 
especially Ptiloris magnificus. The skull is undistinctive and typical of 
the Paradisaeinae (Bock, 1963). Particularly the female plumage, but 
also the above-mentioned features of the male plumage and the bill, 
place Seleucidis near its allies Ptiloris and Lophorina. 

The taxonomic status of these three “genera” is considered later. 


6. Remaining species of Paradisaeinae. 
Five genera of Paradisaeinae remain to be considered. The first 
three of these are “good” monotypic genera whose affinities are obscure. 
Macgregoria pulchra is a high-altitude, monogamous, sexually mono- 
morphic species of particularly obscure affinities, in that it is not even 


$15 


SPECIES ACCOUNTS 


clear whether it belongs to the subfamily Cnemophilinae or Para- 
disaeinae (Bock, 1963). 

Lycocorax pyrrhopterus is confined to the Molucca Islands, where 
the only other paradisaeid is Semioptera. Like the manucodes, which 
it suggests superficially in its bill, size, and uniform glossy dark brown 
color, Lycocorax is monogamous and sexually monomorphic. There is 
no reason to suspect a particular affinity of Lycocorax to any other 
member of the Paradisaeinae, unless Manucodia. Whether its super- 
ficial similarity to Manucodia represents true relationship or conver- 
gence is unclear (Bock, 1963). 

Semioptera wallacei is the other paradisaeid of the Moluccas. The 
female is uniform brown. The male differs only in having a pair of 
long white plumes arising from each shoulder, and a green, laterally- 
expanded breast shield superficially reminiscent of Diphyllodes magni- 
ficus but basically quite dissimilar (Stonor, 1938). The form of the 
ventral feather tract is shared with no other paradisaeid (Stonor, 
1938). ‘The bill is elongated and heavy. Bock (1963) states that the 
skull is typical of the Paradisaeinae and especially resembles that of 
Seleucidis. Clear indications of a particular affinity of Semioptera to 
some other paradisaeine genus are lacking, and the female plumage 
is distinct. 

The Paradigalla superspecies (P. carunculata and P. brevicauda) 1s 
sexually monomorphic, uniformly black, and adorned only by facial 
wattles. This plumage is distinctive for a paradisaeid female (super- 
ficially suggested only by Macgregoria). However, the crown has stif- 
fened blue-green feathers as in Lophorina, Ptiloris, Epimachus, and 
Astrapia males. Hybrids with Lophorina, Parotia and Epimachus fur- 
ther imply affinities to this large group of paradisaeines. ‘The skull is 
apparently typical of the Paradisaeinae (Bock, 1963). 

The last genus, Paradisaea, consists of a superspecies (P. apoda, P. 
rubra, P. raggiana, P. minor, P. decora) plus P. rudolphi of eastern 
New Guinea and P. guilielmi of the Huon Peninsula. ‘The latter two 
are sympatric with the superspecies and inhabit altitudinal ranges that 
lie largely or entirely above that of the superspecies. Some affinities to 
the large group of Paradisaeinae with barred females are suggested by 
the distinctly barred underparts of P. rudolphi females and the ob- 
scurely barred underparts of P. decora females, as well as by hybrids 
with Ptiloris, Diphyllodes, and Seleucidis. Diphyllodes and Cicinnurus 
may be the members of this group to which Paradisaea is nearest, as 
suggested by the following shared features: elongated wire-like central 
rectrices with barbs reduced or absent, the presence of red or yellow 
and absence of black on the back of males (except in P. rudolphi), and 
the upside-down displays of males of P. guilielmi, P. rudolphi, and 
occasionally Cicinnurus regius and P. raggiana.

7. Evaluation of genera of Paradisaeinae. 

Having surveyed the 22 species or superspecies of Paradisaeinae, we 
may now consider how best to draw generic lines. 

Macgregoria pulchra, Lycocorax pyrrhopterus, and Semioptera wal 
lacei are each isolated forms without clear affinities to another species. 
These three, and only these three, members of the Paradisaeinae fulfill 
the criteria of good monotypic genera. Manucodia is an isolated and 
very homogeneous group of four species (one a superspecies). In the 
case of Paradisaea (three species, one a superspecies) there seem to be 
clear affinities with “Diphyllodes” and “Cicinnurus”’, but Paradisaea 
is still sufficiently distinct and compact that its right to stand as a 
genus is unlikely to be disputed. Similarly, the Paradigalla super- 
species is related to the Lophorina complex but constitutes a distinctive 
and acceptable genus. 

The remaining 11 species or superspecies form a related group, as 
indicated by the female plumage of all members, the male plumage of 
most, and hybridization. From this group Epimachus (including 
Drepanornis; three species, one a superspecies) deserves to be sub- 
tracted as a separate genus, because its species share the most strikingly 
distinct bill in the family and form a compact group which has 
radiated in three easily reconstructed speciations. 

The assignment of the other eight species or superspecies of the 
group provides the most recalcitrant obstacle to a satisfactory generic 
revision of the Paradisaeidae. It may be recalled that within this 
group “Diphyllodes’ and “Cicinnurus’ form one closely-knit sub- 
group, “Lophorina”, “Parotia’, and “Ptiloris” form another subgroup, 
and “Astrapia’, “Seleucidis”, and “Pteridophora” are each separate. 
One solution would therefore be to recognize five genera, two polytypic 
and three monotypic. Against this solution one may object that it 
fails to express taxonomically the interrelationships within the group, 
that it exaggerates the distinctness of the members by comparison with 
the other much more distinct paradisaeid genera, and that neither 
Astrapia, Pieridophora, nor Seleucidis has characters warranting erec- 
tion of a monotypic genus, if one rejects ornamental plumes as a 
proper basis for monotypic genera. Alternatively, the eight species 
could be placed in a single genus (Lophorina) of five subgenera 
(Cicinnurus, Lophorina, Astrapia, Seleucidis, and Pteriodophora), as 
illustrated in Table 10 (p. 321). This has the disadvantage that eight of 
the 22 members of the subfamily Paradisaeinae would be placed in one 
rather large genus, and that the differences between some of the 
species in this genus would be greater than the differences among 
congeneric species in the other polytypic genera (Manucodia, Para- 
disaea, Epimachus). ‘The former point is less a disadvantage than 
simply a recognition of a biological reality, that the subfamily does 
consist of a group of eight species plus several more isolated groups or 


317

species. ‘Vhe latter difficulty is inevitable in translating a phylogenetic 
tree into hierarchical nomenclature with a finite number of levels: the 
possible distances between species of the tree vary continuously, and 
it is therefore impossible to attain a nomenclature in which the dis- 
tances between all units on the same level are equal. On the whole 
the arrangement of Table 10 appears to me the least unsatisfactory 
one I can devise at present, in expressing relationships and in minimiz- 
ing variation in differences between taxonomic units on a given level. 


8. Subfamily Cnemophilinae. 


As presently construed, this subfamily consists of three monotypic 
genera, Cnemophilus (macgregori), Loria (loriae), and Loboparadisea 
(sericea). Bock (1963) showed that these three species resemble each 
other, and differ from the species of Paradisaeinae, in several features 
of skull construction sufficiently distinctive to warrant placing these 
three birds in a separate subfamily. 

Among these three species Loria loriae, which De Vis initially de- 
scribed in the genus Cnemophilus, and Cnemophilus macgregorii 
resemble each other, and differ from Loboparadisea, in several morpho- 
logical respects. Loboparadisea is a smaller bird (weight 62-77 g vs. 
80-100 g for the other two species). ‘he underparts of the adult male 
are yellow in Loboparadisea, velvet-black (Loria) or brownish velvet- 
black (Cnemophilus) in the other two. ‘The females of Cnemophilus 
and Loria are unpatterned and rather uniform-colored birds: Cnemo- 
philus, olive-brown, slightly paler below; Lora, olive, paler and more 
yellow below, olive-brown on the wings and tail. Both Cnemophilus 
and Loria females present a slightly scaled appearance due to obscure 
dark feather margins. Loboparadisea females have a distinct pattern 
dorsally, in that the head and upper back are olive-brown, the lower 
back and rump yellow, and the tail rufous-brown; the underparts are 
yellow. Loboparadisea has a distinct immature plumage which is 
streaked ventrally and which is otherwise more like adult females of 
Cnemophilus than of Loboparadisea, whereas in the cases of Loria 
and Cnemophilus immatures resemble the adult female. Cnemophilus 
and Loria females are sufficiently similar that when Shaw-Mayer and 
Loke Wan Tho discovered the nest of Cnemophilus and obtained a 
high quality close-up photograph of the female at the nest in sharp 
focus, the bird was misidentified as Loria, Sims (1956, p. 426) described 
the nest under Loria, Gyldenstolpe (1955, Pl. XI) published a 7” > 5” 
reproduction of the photo labeled as Loria in his report on his collec- 
tions, and the misidentification was still not recognized until years 
later. In dorsal coloration adult males of Loria and Cnemophilus differ, 
since Loria is velvet black dorsally as ventrally, while Cnemophilus 
is yellow-orange anteriorly becoming browner posteriorly and on the 
wings. In addition, Cnemophilus has a short, slender crest of six 
feathers. Loboparadisea adult males are distinctively patterned as the 


318 


SPECIES ACCOUNTS 


adult females but with brighter colors, and have pale blue-green wat- 
tles at the base of the bill. 

Ecological and distributional evidence alone would suffice to indicate 
a close relation between Cnemophilus and Loria. Both species live 
mainly in the understory (unlike the more arboreal Loboparadisea) 
and feed on fruit. The local altitudinal ranges of the two species 
appear to be mutually exclusive, with the transition altitude around 
7,600 ft on Mt. Karimui (Cnemophilus at higher altitudes, Lorva 
lower). The geographical range of Cnemophilus is confined to south- 
eastern New Guinea and the Eastern Highlands, a distribution shared 
by only five other montane species, all products of a recent speciation. 
One of these, the semispecies Parotia lawesi, is still allopatric to its 
relatives; Astrapia stephaniae is largely allopatric to its relatives but 
overlaps A. mayeri at the western extremity of its range, the two forms 
living in mutually exclusive altitudinal bands; while the geographical 
ranges of the other three, Ptiloprora guisei, Amblyornis subalaris, and 
Paradisaea rudolphi, are shared completely with their more wide- 
spread congeners Ptiloprora perstriata, Amblyornis macgregoriae, and 
Paradisaea raggiana, with the two forms segregating altitudinally in 
each case. These five cases represent stages in a shared speciation pat- 
tern, in which the range of a southeastern New Guinea isolate of a 
superspecies is reinvaded and completely overrun by the next isolate 
to the west, the southeastern isolate also gradually extends westward, 
and sympatry is made possible by altitudinal segregation. By analogy 
Cnemophilus probably evolved as a southeastern New Guinea isolate 
of a superspecies including Loria. ‘The course of speciation seems to 
have proceeded equally far in the cases of Cnemophilus macgregorit, 
Ptiloprora guisei, and Paradisaea rudolphi, all three of which now 
share their entire geographical ranges with the sister species and have 
extended westward to somewhere between long. 143°30’ E and 142°E. 

For these reasons the species loriae and macgregorit should again be 
considered congeneric, as De Vis did initially. Cnemophilus has priority 
as the genus name, and Loria becomes a synonym. Loboparadisea 
remains as an allied but monotypic genus. 


Conclusions. 


The classification tentatively arrived at is summarized in Table 10. 
The 25 species or superspecies are now distributed among 10 rather 
than 20 genera, yielding a species-to-genus ratio of 2.5. Of the 10 genera, 
five are monotypic, one contains two species, two contain three species, 
one contains four species, and one contains eight species. All of the 
10 discarded genera are monotypic, five in the strictest sense, five in 
the sense of consisting of a single superspecies. 

Nomenclatural problems which would result from this classification 
are that the species name of “Ptiloris” magnificus (described as Fal- 
cinellus magnificus by Vieillot in 1819) would become preoccupied by 


319 


SPECIES ACCOUNTS 


that of “Diphyllodes” magnificus (described as Paradisaca magnifica 
by Pennant in 1781) as a result of both being transferred to the genus 
Lophorina; and that the species name of “Pteridophora’ alberti (de- 
scribed under the same name by Meyer in 1894) would become pre- 
occupied by the race “Ptiloris” magnificus alberti (described as Ptiloris 
alberti by Elliot in 1871) as a result of both being transferred to 
Lophorina. However, coining of new names seems unwise, and likely 
to lead only to confusion, until these and perhaps other proposals 
for generic reclassification of birds of paradise have been more widely 
discussed and until more evidence has accumulated. For the present, 
in referring to paradisaeid species whose familiar generic names I 
proposed to discard, I shall continue to cite this discarded name in 
parentheses: e.g., Lophorina (Ptiloris) magnifica, Lophorina (Diphyl- 
lodes) magnifica, Epimachus (Drepanornis) albertisii, and Cnemophilus 
(Loria) loriae.

underparts than sanguineus (Mayr and Gilliard, 1954, p. 361). Since 
examination of the type of kwboriensis showed that it was extremely 
similar to sanguineus, and since only one other species (Peneothello 
sigillatus) exhibits subspecific differences between Mt. Hagen and the 
Kubor Range (50 miles from Mt. Hagen), detailed comparison of the 
following material was undertaken: two adult males (including the

Hagen. Average wing lengths from the three localities are the same 
within 1 mm. Two Mt. Hagen specimens and the Mt. Karimui adult

birds, and the Mt. Karimui adult is slightly deeper orange on the head 
than the Mt. Hagen birds, but these differences are also trivial. Hence, 
kuboriensis must be synonymized with sanguineus.

DISCUSSION. Cnemophilus macgregorii occurred from 7,620 ft 
to the summit (8,165 ft) on Mt. Karimui, and has also been collected 
by Gilliard, Shaw-Mayer, Bulmer, and Hitchcock between 8,000 and 
11,000 ft on Mt. Giluwe, Mt. Hagen, and the Kubor Range in moss 
forest. The western limit of its range must lie somewhere between Mt.

Giluwe and Telefolmin but remains to be determined. It is usually 
seen in fruit trees, sometimes up to 60 ft above the ground but more 
often in the understory. Its movements are characteristically abrupt, its 
wingbeat loud. Once I watched a group of two adult males and two 
birds in female plumage, moving singly or together 3-40 ft above the 
ground, often with all four birds within 3 ft of each other, periodically 
stopping to eat berries. They occasionally gave low harsh calls, and 
the wings whirred loudly in flight, but the two males appeared not to 
react to each other, and there was no suggestion of a display. South- 
eastern New Guinea natives on Mt. Albert-Edward told me that C. 
macgregortt does not carry out a display (“he no sing-sing, he walk- 
about nothing that’s-all’’), and Gilliard was given the same information 
in the Eastern Highlands.

TAXONOMY. Subspecies are founded on the iridescent color of 
the inner secondaries of adult males viewed in good light: solid violet 
in amethystinus, blue-green in inexpectatus, between violet and blue- 
green in nominate loriae. Eastern Highlands specimens are unmis- 
takably amethystinus. Gyldenstolpe’s (1955, p. 142) suggestion, ad- 
vanced without comparative material being available, that Eastern 
Highlands birds might be C. /. loriae is untenable. ‘The gape is white. 

BREEDING. ‘The testes were moderately enlarged in four of the 
males, small in the other three. 

DISCUSSION. Although Cnemophilus loriae was apparently not 
uncommon between 5,300 and 7,600 ft on Mt. Karimui, I never saw 
it in the field and obtained no evidence of its presence on Mt. Michael. 
The frequency of netted individuals indicates lowerstory habits. Gil- 
liard, Gyldenstolpe, Shaw-Mayer, Bulmer, and Hitchcock all collected 
Cnemophilus loriae at various altitudes in forest between 6,000 and 
9,000 ft. My highest record of it on Mt. Karimui came 20 ft below the 
lowest record of Cnemophilus macgregoru, and the altitudinal distri- 
butions of these congeners also appear to complement each other at 
other localities, with little overlap.

Telefolmin, 1 imm. ¢; unknown locality in Dutch New Guinea, | ¢. 
In color the adult males from Mt. Karimui are indistinguishable from 
nominate sericea. They differ from aurora in that the top of the head 
is olive-brown darker than the back, rather than olive scarcely darker 
than the back; in that the back is less pale and less yellow; and in that 
the primaries are darker. In the initial diagnosis of aurora, Mayr 
(1930, p. 147) also cited paler yellower underparts with a green in- 
stead of orange tone. The underparts of the one aurora specimen 
available to me are paler than the Mt. Karimui males or two Weyland 
Mountains males but can be matched exactly by other Weyland 
Mountains males, five of which have a green tone. 

Measurements of wing length are given in Table 11. There is ob- 
vious variation, but it is too irregular to use as a subspecific character. 
In the Weyland Mountains females are larger than males, but this is 
not the case on Mt. Karimui. A single adult male which was received 
by Gyldenstolpe from the Jimmi River and which was described as 
closer to nominate sericea in color has a wing length equal to the 
average value for Mt. Karimui males (Table 11). 

What Rand and Gilliard (1967, p. 505) describe as the adult female 
is actually the immature plumage. Adult females have the same pat- 
tern as adult males but duller colors. ‘The wattles of the male are very 
pale blue-green in life. 

BREEDING. Gonads were enlarged in three of the five adult 
males, small in all other specimens. 

DISCUSSION. Loboparadisea sericea exemplifies to an extreme 
degree the patchiness of distribution characteristic of numerous New 
Guinea birds, especially some birds of paradise. It was common on 
the west ridge of Mt. Karimui, but Gyldenstolpe’s Jimmi River speci- 
men is the only other Eastern Highlands record. It appears from 
published records to be common on Mt. Kunupi of the Weyland 
Mountains, on the Utakwa River of southwestern New Guinea, and at

I never observed Loboparadisea in the field and can offer only the 
statement of my native assistants that they found it in the treetops, 
which is consistent with no specimens having been netted. As with 
some other hill forest species like Charmosyna pulchella and Rhipidura 
atra, the intrusion of the flat Karimui Basin has given it a discon- 
tinuous altitudinal range: present at Soliabeda (2,000 ft), absent at 
Bomai (3,250 ft) and Karimui (3,650 ft), present between 4,000 and 
5,890 ft on Mt. Karimui. ‘The population structure follows the usual 
pattern, with two of the three immatures coming from lower altitudes 
than any of the adults, and the Soliabeda immature (2,000 ft) a full 
2.400 vertical feet below the lowest adult (4,400 ft).

orange with age: the iris was orange to red in adult males (with 
crinkled breast and throat feathers) and in most females examined, 
two of which were in breeding condition, but was orange-brown or 
brown in subadult and immature specimens. A convoluted trachea 
was present in adult males. 

Subadults and immatures of M. chalybatus can be very difficult to 
distinguish from subadults and immatures of M. ater, because the 
distinctive glosses and feather shapes of the adults are lacking. Hence 
measurements were made of both species in southern New Guinea 
(Fly River) and southeastern New Guinea, with the results tabulated 
in Table 12. The most consistent difference is the longer tail of M. 
ater. In southeastern New Guinea M. ater has a longer wing than 
M. chalybatus, but on the Fly River there is much overlap. On the 
Fly River the dorsal sheen is a useful character except in immatures, 
since the sheen is consistently more green in M. ater there and more 
purple in M. chalybatus. ‘This character is of less use in southeastern 
New Guinea, where M. ater is more purple. M. ater is mainly a low- 
lands species, M. chalybatus a hill forest species. 


BREEDING. ‘The two females examined at Karimui in 1964 had 
greatly enlarged ovaries with a nearly full-sized egg, and one crinkled 
Karimui male in 1965 had the testes slightly enlarged, but the gonads 
were small in other specimens. 


DISCUSSION. Single individuals or pairs of M. chalybatus were

not uncommon at Karimui and in Zone 1 of Mt. Karimui (1% of the 
local avifauna) but were inconspicuous, quiet, and remained in the 
middle- and upperstories. At Soliabeda, which was probably near the 
bottom of the altitudinal range, the sole record was an immature 
brought in by natives, and the ceiling on Mt. Karimui was around 
4,750 ft. Bulmer also found the species present but very inconspicuous 
in Kyaka territory up to at least 5,500 ft, and collected a pair of breed- 
ing birds at a nest at 5,000 ft. Schodde and Hitchcock obtained it at 
Lake Kutubu (2,450 ft). The silhouette in flight is similar to that of

quick, convulsive flaps while jerking the tail, then a short glide.

TAXONOMY. ‘The series was compared with purpureoviolaceus 
of southeastern New Guinea, jamesi of the Fly River, Aru Islands, 
and Baroka (southeastern New Guinea lowlands west of Hall Sound), 
neumanni from the Wahgi and Sepik Mountains, and nominate 
keraudrenit from the Weyland Mountains and Vogelkop. Awande- 
Okasa birds have rather green underparts and blue-violet wings, tail, 
and back and are closest to Fly River jamesit, from which they differ 
in having the underparts, wings, and tail slightly, and the back con- 
siderably, more purple and less green. However, in the color of the 
back they are only slightly more purple than Aru Islands jamesii. 
Of the Karimui-Mt. Karimui birds, two are quite green above, as are 
most from the Fly River; one is more blue-violet above and can still 
be matched exactly by some Fly River birds; and the remaining two 
are still more blue-violet, both on the back and on the wings, like 
Awande-Okasa birds. ‘These differences indicate that my series is inter- 
mediate morphologically, as it is geographically, between the Fly River

(jamesii) and southeastern New Guinea (purpureoviolaceus); and that 
the more westerly-lying Karimui series is nearer jamesi, as one would 
expect. The differences are more marked compared to purpureo- 
violaceus, which is much more purple on the underparts, back, wings, 
and tail. One specimen collected by the Sixth Archbold Expedition in 
the Kassam Pass belongs to purpureoviolaceus. ‘The head plumes in 
my series are unusually long. M. k. newmanni is a very deep dull 
violet on the lower back, wings, and tail and is the race to which 
belongs one Nondugl aviary specimen (given to Gilliard) of unknown 
provenance but presumably from the northern watershed of the 
Eastern Highlands. Thus, birds in the southern, northern, and eastern 
parts of the Eastern Highlands are distinct and referrable to three 
races: jamestt, neumanni, and purpureoviolaceus. 

The immature has less gloss and a smaller crest and beard. 

BREEDING. ‘The 1964 Okasa male had greatly enlarged testes, 
but gonads were small in all other specimens examined. 


DISCUSSION. Although in some other parts of New Guinea 
(notably the mouth of the Fly River) Manucodia keraudrenii regularly 
reaches sea level, it is a hill forest species in the Eastern Highlands, 
ranging from 3,500 ft up to a variable ceiling at 6,200 ft (Okapa area) 
or less (4,600 ft on Mt. Karimui). The only record at Karimui (3,650 ft), 
near the bottom of its range, was of the one immature male. Most 
of the altitudinal range of M. keraudrenii lies above that of M. chaly- 
batus. Sightings were of solitary individuals in the middle- or upper- 
story of the forest, except for a pair at Miarosa in a casuarina grove 
a few hundred yards from the forest edge. One was seen in a fruiting 
tree at Miarosa. 


VOICE. A prolonged, hoarse, harsh note with a peculiar quality, 
similar to the sound humans produce in response to a doctor’s request, 
“Open your mouth and say a-a-ah.” Also, a musical, downslurred, 
slightly nasal “kyew”, similar in quality to the call of Philemon nova- 
equineae.

it as ‘common in the forest crown between 6,500 and 8,000 ft but diffi-

Bulmer (pers. comm.) found it “common at forest edge and in forest

Epimachus fastosus stresemanni Hartert 


Black Sicklebill 
NATIVE NAMES. Fore: kumpi. Gimi: kurikuri. Daribi: padukwa. 


DISCUSSION. Like several other birds of paradise, Epimachus 
fastosus is at some localities common and at other similar localities 
absent. On Mt. Karimui, I heard E. fastosus males calling most days 
from about 5,200 to 7,300 ft and saw a female or immature male at 
the top of a tree at 5,400 ft. Neither Shaw-Mayer nor Gyldenstolpe 
collected it; Gilliard encountered only one male at 7,500 ft on Mt. 
Hagen; in Kyaka territory Bulmer (pers. comm.) found it “fairly 
common at forest edge and in forest 6,000-7,000 ft’; and Burgers 
found it common on the Schraderberg. 

VOICE. The male’s call consists of two identical, sharp, liquid 
notes in immediate succession, with considerable carrying power: 
“buk-buk”, like the call of a foraging domestic chicken but much 
sharper and louder. On Mt. Karimui males never called on the ridge 
crest but only from the steep flanks of the ridge, which I also found to 
be the case with the isolated population of Epimachus fastosus ultimus 
on Mt. Menawa in the North Coastal Range (Diamond, 1969) and with 
Epimachus meyer.

STOMACH CONTENTS. ‘Two mm fruits (two stomachs); insects and 9 mm fruit

DISCUSSION. ‘This sicklebill occurs at 8,000-9,500 ft on Mts. 
Hagen, Kubor, and Wilhelm, the Wahgi Mountains, and the Schrader 
Range. Its altitudinal range and that of its lower-altitude congener 
E. fastosus are mutually exclusive. In southeastern New Guinea, where 
E. fastosus is absent, I have found E. meyerz down to 5,000 ft. It 
ranges from 10 ft above the ground to the crowns, and congregates in 
fruiting trees. 

VOICE. Adult males call from the steep flanks of ridges, two or 
three individuals within earshot of each other. ‘he reverberating, 
totally unmusical call lasts 2 sec, is repeated at intervals of about 2 
min, and consists of three double notes. ‘he quality may be com- 
pared to the sound of a pneumatic drill, a burst from a machine gun, 
or a trash can lid being slammed on the pavement and its sound being 
quickly damped out.

TAXONOMY. Reexamination of available material indicates that 
only two thinly differentiated races are worth recognizing: nominate 
albertisii (including geisleri) from the Vogelkop, Wandammen Penin- 
sula, and Huon Peninsula; and cervinicaudus (including inversus) 
from the Central Range. In the adult male, adult female, and imma- 
ture male cervinicaudus has a slightly paler upper tail and slightly 
lighter, duller, more olive back than albertisii. I cannot detect the 
alleged slight color differences between the populations of the Huon 
Peninsula (‘“geisleri’”) and the Vogelkop (nominate albertisi) after 
comparing adult males, adult females, and immature males from both 
areas. The Karimui population is slightly darker on the back than 
cervinicaudus of southeastern New Guinea but otherwise matches. 


DISCUSSION. Epimachus albertisii is an uncommon and local 
species, especially in the main body of New Guinea, where the Karimui 
series provides the first record for the southern watershed. ‘There ap- 
pear to be three locality records for the northern watershed (Mt. 
Kunupi in the Weyland Mountains at long. 135°30’E, the Lordberg 
in the Sepik Mountains at long. 143°E, and the Herzog Mountains at 
long. 147°E), in addition to records for four peripheral areas (the 
Vogelkop, Wandammen Peninsula, Huon Peninsula, and southeastern 
New Guinea). Rand and Gilliard (1967, p. 470) and Mayr (1941b, p. 
170, and in Mayr and Greenway, 1962, p. 189) state that the range 
includes the northern slopes of the Central Range from the Weyland 
Mountains to the Lordberg, but this is an incorrect assumption: there 
are no records at all between the Weyland Mountains and the Lord- 
berg. ‘This area includes the entire range of the closely related and 
equally uncommon Epimachus (Drepanornis) bruijnii (ca. long. 136- 
141°E in the lowlands of the northern watershed). The hill slopes in 
this area have been intensively surveyed by the Third Archbold Ex- 
pedition around long. 139°E (northern slope of the Snow Mountains), 
by Mayr around long. 140°30’E (Cyclops Mountains) and by me be- 
tween long. 141°30’E and 143°30’E in the North Coastal Range, and 
(less intensively) by van Heurn on the Doormanpad (long. 138°30’E) 
and by Gilliard at ‘Velefolmin (long. 141°30/E), so that the apparent

absence of E. albertisii in this area is probably real, and it and E. 
bruijnit are probably still allopatric and constitute a superspecies. In 
addition, their altitudinal ranges are different, since E. bruijnii is 
known only near sea level and E. albertisii only in the hills and moun- 
tains (3,650-4,200 ft in the Karimui area). On Mt. Karimui the highest 
record of E. albertisii was 1,000 ft below the lowest record of E. fasto- 
sus, so that the altitudinal ranges of these two similar species are mu- 
tually exclusive. 


VOICE. Karimui natives pointed out to me a call from the tree- 
tops which they said belonged to this species. It consisted of a rapid 
and loud series of over a dozen musical notes which progressively 
increased in volume and dropped slightly in pitch. This call is similar 
to the description of the call of this species by Stein (1936, p. 26) and 
of E. bruijnii by Ripley (1964, p. 48).

TAXONOMY. Iredale (1948) founded a race addenda on a single 
adult male from the Hagen district, citing apparently striking differ- 
ences in the cape, the frontal shield, and the breast feathers. Mayr and 
Gilliard (1954, p. 358) and Gyldenstolpe (1955, p. 133) did not recog- 
nize addenda, because adult males from the Hagen district and other 
parts of the Eastern Highlands proved indistinguishable from males 
from other parts of the Central Range. However, there has been no 
agreement as to the correct assignment of the Eastern Highlands popu- 
lation, which has been variously placed with feminina (Mayr and Gil- 
liard, 1954; Mayr, in Mayr and Greenway, 1962, p. 193; Rand and Gil- 
liard, 1967), with pseudoparotia (Gilliard and LeCroy, 1961), or with 
a resuscitated addenda (Gilliard, 1969) on the basis of female char- 
acters. In fact, comparison of Eastern Highlands females with those 
of other races shows that they are clearly closest to latipennis of the 
Huon Peninsula, from which they differ only in being slightly darker 
above. From feminina they differ obviously in the crown being blacker 
and less brown, and in having much less white speckling, the under- 
parts having much less ochraceous wash, and the back being darker

SPECIES ACCOUNTS 


and more olive. The race minor of southeastern New Guinea differs 
in the crown being slightly more blackish and the back much warmer 
brown; nominate superba (Vogelkop) and niedda (Wandammen Penin- 
sula) in the crown being an unspeckled black and the superciliary 
stripe greatly reduced. ‘Topotypical specimens of pseudoparotia (Sepik 
Mountains), which were not available to me for comparison, were 
noted by Stresemann (in Gyldenstolpe, 1955, p. 132) and by Mayr and 
Gilliard (1954, p. 358) to be browner and less olive dorsally than 
Eastern Highlands females. The race connectens of the Herzog Moun- 
tains 1s eintually indistinguishable from latipennis and must be con- 
sidered a synonym. Eastern Highlands males have distinct black 
centers to the feathers of the breast shield, as do males of all other 
populations except nominate superba and niedda. 

BREEDING. ‘The gonads were much enlarged in one female, 
small in the others; small in immature males, and enlarged in most 
adult males. 

DISCUSSION. In my study areas Lophorina superba was the com- 
monest bird of paradise within its altitudinal range (ca. 3,500-7,000 ft), 
and accounted for 3°% of the local avifauna at 5,400-6,000 ft on Mt. 
Karimui. There was marked change in population composition with 
altitude on Mt. Karimui. Zone 1 yielded only an immature male, and 
Zone 2 two females or immature males. Zone 3 yielded females, and 
the first adult male was heard calling at 5,115 ft. Adult males were 
commonest in Zone 4, where females remained until 5,700 ft. Above 
5,700 ft few Lophorina superba were encountered, all adult males. At 
the bottom of the forest on Mt. Michael (ca. 7,000 ft) there were a few 
Lophorina superba, all adult males. ‘This change in sex ratio with alti- 
tude, though true of many other species, is particularly marked in birds 
of paradise, as initially reported by Stein (1936). 

There are also some differences in the habits of adult males as op- 
posed to immatures and females. Adult males call and display high in 
the crowns, though not at the very tops, of leafy trees. In ecologically 
disturbed areas these display trees are often at the forest edge or in 
partly cut areas, to a greater extent than with the other midmontane 
birds of paradise. Females and immatures spend proportionately twice 
as much time’in the understory as adult males. Females and adult 
males were never seen together, and Paran said that nestlings were fed 
solely by the female. ‘Verborgh found Lophorina superba feeding in 
fruit trees at Okasa and Miarosa. It is generally solitary and moves 
slowly. 

VOICE. The call of the adult male is a series of seven to ten very 
harsh, raucous, utterly unmusical notes within a span of 5 sec. Suc- 
cessive notes in the series become lengthened and louder and decelerate 
greatly. A given individual repeats the series from the same perch at 
intervals of about 10 min.

Lophorina (Parotia) carolae subsp.1 
Queen Carola’s Six-wired Bird of Paradise 


To date there are three Eastern Highlands records, all from the 
northern watershed: a single female at the Nondugl aviary, possible 
from the Jimmi River region, which Mayr and Gilliard (1954, p. 358) 
assigned to the race chrysenia despite some differences; a male and 
a female from the Jimmi Valley, which Gyldenstolpe was unable to 
assign to an existing subspecies; and one native-prepared skin Bulmer 
obtained in the Schrader Range, where he also obtained Lophorina 
(Parotia) lawest. 

The four semispecies of “Parotia” form a superspecies, with two 
members (L. sefilata of the Vogelkop and L. wahnesi of the Huon 
Peninsula) confined to peripheral mountain “islands”. In the main 
body of New Guinea, L. carolae is the western semispecies and L. 
lawesi the eastern semispecies. From present distributional information 
it appears that the ranges of the two forms meet around long. 144- 
145°E. The details of the transition may prove as interesting as in 
the case of the Lophorina (Astrapia) mayeri-L. (Astrapia) stephaniae 
transition.

TAXONOMY. Iredale (1948, p. 162) founded the race exhibita on 
a single female from the Mt. Hagen district, remarking that a single 
male was indistinguishable from nominate lawesi. His diagnosis reads: 
“But the female shows valid colour differences in the marking of the 
under-surface, the whole being rather deep rufous, closely crossbanded 
throughout from chin to under tail-coverts, while the upper surface is 
also a deeper red brown.” Since subsequent collectors obtained no 
females, the validity of exhibita has remained unchecked. ‘The above 
series from the Eastern Highlands was carefully compared with 
nominate lawesi from southeastern New Guinea. Adult males were 
found to be indistinguishable except, apparently, for a slightly longer 
wing in Eastern Highlands birds. ‘The females showed no difference 
in the closeness of the barring of the underparts nor in the color of 
the upperparts. Of seven Eastern Highlands females examined, three

agreed in the color of the underparts with most southeastern New 
Guinea females, while the other four were slightly duller and less 
rufous below. Hence exhibita cannot be recognized. An adult male 
collected by the Sixth Archbold Expedition at Purosa near Okapa 
has a wing of 158 mm, and Gyldenstolpe (1955, p. 131) gives 150 mm 
and 154 mm for the wings of two males from the Jimmi Valley (north- 
ern watershed). My measurements of southeastern New Guinea lawest 
give average wing lengths of 151.6 mm for adult males and 142.5 mm 
for females, so that birds from the southern watershed of the Eastern 
Highlands average slightly larger. 

I examined the color of the iris in eight individuals from the Eastern 
Highlands (1 ad. ¢, 2imm. ¢,5 ¢), and in all cases it was blue. Eye 
color is indicated on the labels of 40 specimens from southeast New 
Guinea in the American Museum of Natural History (21 ad. ¢, 12

two cases (1 imm. ¢?, 1 ¢) the label states yellow; and in one case 
(limm. ¢), brown. In Lophorina (Parotia) carolae (3 ad. ¢, 8 imm. 
6,6 ¢@) the iris color is given as yellow-green, yellow, or whitish. ‘The 
statement by Rand and Gilliard (1967, p. 483) that the iris is yellow in 
the adult male of L. lawesi and pale blue in the female of L. carolae is 
therefore incorrect and reversed. The gape in the specimens I ex- 
amined was yellow. 

BREEDING. Gonads of all specimens were small. 


DISCUSSION. On Mt. Karimui Lophorina lawesi occurred be- 
tween 4,000 and 5,700 ft, while it occurred up to at least 6,000 
ft in the Okapa area. There are at least three locality records from 
the northern watershed: (1) Bulmer collected it in Kyaka territory in 
forest and at the forest edge, at 5,300 and 6,000 ft; (2) Bulmer collected 
two females or immatures in the Schrader Range; (3) Gyldenstolpe 
was given two males from somewhere in the Jimmi Valley. As dis- 
cussed under L. carolae, these records are of interest in making it 
likely that the ranges of L. carolae and L. lawesi meet.

TAXONOMY. My measurements of females give: the eastern race 
intercedens, 9 ¢ from southeastern New Guinea, exposed culmen 37- 
41 (39.9), wing 141-155 (148.8); the western race magnifica, 8 9 (Fly 
River, southern slope of Snow Mountains, Weyland Mountains, Hum- 
boldt Bay, Idenburg River), exposed culmen 50-53 (51.6), wing 148-157 
(151.8). ‘The Soliabeda adult female is nearer magnifica, but a firm 
racial assignment will have to await examination of adult males. 
Schodde and Hitchcock assigned the Lake Kutubu population to nomi- 
nate magnifica. 

BREEDING. The Soliabeda female examined was an adult with 
enlarged ovaries, whereas the smaller Karimui female had very small 
ovaries. 

DISCUSSION. The Magnificent Riflebird was uncommon in the 
Karimui area (0.2-0.3% of the local avifauna) up to about 4,000 ft on 
the lowest slopes of Mt. Karimui. Females or immature males were 
observed singly a few times in the middlestory of the forest. Adult 
males were never seen, but their powerful calls showed that they had 
a regular but very sparse distribution at intervals of about one-half 
mile to a mile. 

On two occasions at Karimui I observed a display between two birds 
in female-like plumage (probably one a female and the other an 
immature male. ‘The immature male and the female with small ovaries 
were collected together at Karimui with bow and arrow by a native 
and may also have been displaying). In the first case (7 Aug. 1964) the 
two birds alighted next to each other on a branch 15 ft above the 
ground at the top of a bush at the edge of the forest. One bird faced 
the other, reared up on its legs, spread out its wings and bent them 
backwards, threw back its head, and remained in this uncomfortable 
posture for some time. ‘The second bird then assumed this posture, and 
finally both assumed it simultaneously before flying off. No calls had 
been given. On the second occasion (12 Sept. 1965) two birds perched 
facing each other on a branch 30 ft above the ground in forest. One 
tilted its body up until it was vertical, held the tail back at right 
angles to the body so that it was horizontal, opened the wings and 
bent them at the shoulder so that they nearly met behind the back 
and the breast was arched towards the partner, and then rose up and 
down on its legs like a horseman posting on a trotting horse. ‘The 
pair flew off to a branch of another tree and repeated the display. A 
less powerful version of the usual adult male call was periodically 
given. The display of a captive adult male is apparently similar (Rand 
and Gilliard, 1967, p. 487). 

VOICE. The colossal whistles of the adult male are among the 
most powerful and beautiful bird songs in New Guinea. ‘These calls 
consist of either two or three upslurred whistles, each lasting nearly 
1 sec and followed by the next at an interval of less than 1 sec. Each 
note starts at approximately the same pitch (an octave or less above 


334 


SPECIES ACCOUNTS 


middle C). The first slur sweeps a full octave upscale, the second slur 
has a smaller sweep (of a sixth or a seventh), and the third note (if 
there is one) a still smaller sweep. When the singer is close, one can 
hear that the beginning of each slur is slightly hoarse, but the quality 
is otherwise full and mellow. The singer remains hidden in the crown 
of a tall tree and calls every few minutes. In Zone 2 of Mt. Karimui, 
700 feet above the last riflebird, these whistles were still readily audible 
coming up from below, and each singer probably hears his next rival 
a half mile or more distant.

TAXONOMY. ‘The adult males are closest to hunsteini of south- 
eastern New Guinea, from which they differ only in that the back is 
brighter and lighter red than most (but matched by some) hunsteznz. 
They differ from chrysoptera in the brighter brick-red midback, and 
the brighter, more orange, less brown crown; and from nominate 
magnifica and intermedia in the brighter orange scapulars and inner 
secondaries. Gyldenstolpe found that birds from south of the Wahgi- 
Sepik Divide were hunsteini and those north of the Divide were 
chrysoptera, which seems reasonable, since the passes all lie above the 
altitudinal ceiling of the Magnificent Bird of Paradise and it has no 
tendency to wander above this ceiling. ‘here are few or no racial dif- 
ferences in the females. 


BREEDING. ‘The two adult males had large testes. Gonads were 
small in most females and in immature males in female-like plumage. 


DISCUSSION. ‘The Magnificent Bird of Paradise is the commonest 
bird of paradise and one of the most abundant birds in hill forest, 
even in ecologically disturbed areas, dropping out towards sea level 
and with a ceiling around 4,000-5,000 ft. In the Karimui area the 
population composition and abundance were as follows: Soliabeda 
(2,000 ft), 1.79% of the local avifauna, immature males twice as numer- 
ous as females, few adult males; Karimui (3,650 ft), 2.7%, females 
slightly more common than immature males, few adult males; Mt. 
Karimui Zone | (4,000-4,200 ft), 2.4%, and Zone 2 (4,400-4,750 ft),

SPECIES ACCOUNTS 
2.9%, adult males increasingly common; lower half of Zone 3 (4,750- 

5,080" it), 123°, mainly adult males; no higher records. 

In my experience the variations in the altitudinal limits of Lopho- 
rina (Diphyllodes) magnifica are correlated with those of Lophorina 
superba, and the two species seem to represent each other altitudi- 
nally, a conclusion consistent with records of expeditions in other 
parts of New Guinea. On Mt. Karimui the lowest adult males of L. 
superba appeared (5,115 ft) just above the altitude where the highest 
males of L. (Diphyllodes) magnifica dropped out (5,080 ft). Some fe- 
males and immatures of L. superba extended 1,000 feet downward 
into the range of L. (Diphyllodes) magnifica. From 2,000 to 6,000 ft 
in the Karimui area the sum of the contributions of these two species 
to the avifauna was approximately constant (1.6-3.7%), with only L. 
(Diphyllodes) magnifica below 4,000 ft, only L. superba above 5,000 ft, 
and their abundances in the overlap zone changing in complementary 
fashion. The absence of L. (Diphyllodes) magnifica at Okasa was cor- 
related with the downwards extension of L. superba’s range at Okasa 
to well below 4,000 ft. Although the plumage and mating display of 
the adult males are quite different, the calls of the adult males, the 
plumage of the females, and the behavior of these two species are 
very similar and reinforce the impression of close relationship drawn 
from the altitudinal distribution. 

Females and immature males are solitary and move about sluggishly 
in the middle- and lowerstory. Adult males were much less often 
seen than heard, but also seemed to spend a good deal of their feeding 
time in the understory. As with L. superba, females and adult males 
were rarely or never seen together and may meet only to mate. An 
adult female was once seen feeding a juvenile male. Individuals some- 
times perch sidewise on the trunks of saplings in the manner of thicket 
flycatchers, and often hang upsidedown to feed. 

Natives showed me two display areas maintained by adult males, 
one at the Sena River (4,500 ft) and one at 4,350 ft on Mt. Karimui. 
In each case an area of ground 6-8 ft in diameter had been cleared 
completely of leaves and twigs. In this area stood two or three dead 
saplings with their leaves removed. According to natives, the resident 
male displays on these saplings. 


VOICE. The call of the adult male, given from high concealed 
perches im trees, 1s similar to that of L. superba and consists of a half- 
dozen loud, harsh, buzzy, downslurred, low-pitched notes on the same 
pitch, progressively increasing in volume. The L. superba call is 
harsher and decelerates much more markedly. Several males may be 
heard calling in the same general vicinity. I heard one calling near 
one of the two display courts I visited. ‘Ihe females and immature 
males call one to three harsh, downslurred, and quiet “chew’s’”, i.e. a 
shortened and soft version of the male’s call.

TAXONOMY. These belong to the widespread race rex (possibly 
synonymous with regius; Mees, 1964). One immature male with en- 
larged testes was largely in female-like plumage but had the head 
largely red and some red on the primaries and uppertail coverts. 
Gyldenstolpe received a specimen of L. r. similis from the Jimmi Valley 
of the northern watershed, Schodde and Hitchcock took two rex at 
Lake Kutubu (2,450 ft), and Bulmer collected one specimen at 2,000- 
3,000 ft in the Baiyer Valley of the northern watershed. 


BREEDING. All adult males had enlarged testes. 


DISCUSSION. ‘The King Bird of Paradise was fairly common at 
Soliabeda (ca. 1.39% of the local avifauna) but very uncommon at 
Karimui (ca. 0.19%), where it was above its usual altitudinal ceiling. 
The population structure shows the usual change with altitude: im- 
mature males made up about half of the Soliabeda population, with 
adult males and females also present, whereas only adults were found 
at Karimui. My limited observations were of single individuals, male- 
female pairs, or pairs in female-like plumage (females and/or imma- 
ture male) 10-60 ft above the ground in the forest and at forest edge. 
Schodde and Hitchcock (1968, p. 61) remark that at Lake Kutubu 
L. (Cicinnurus) regia frequented second-growth and the forest edge, 
while L. (Diphyllodes) magnifica lived in primary forest.

SPECIES ACCOUNTS 


TAXONOMY. Lophorina (Astrapia) stephaniae occurs from Mt. 
Giluwe (long. 144°E) eastwards, with birds from Mts. Giluwe, Hagen, 
Kubor, Karimui, and Michael referrable to the race ducalis and those 
from the Wahgi Mountains, Mt. Wilhelm, and the Schraderberg to 
feminina. ‘Vhe validity of ducalis as distinct from nominate stephaniae 
of southeastern New Guinea is doubtful and has also been questioned 
by Gillard and LeCroy (1968, p. 25). The supposed difference in 
blackness may be due to foxing, and the difference in wing length is 
slight. 

DISCUSSION.  L. stephaniae has been encountered by all collectors 
at virtually all forested localities in its altitudinal (5,000-8,000 ft) and 
geographical range, but its abundance is subject to marked local varia- 
tion. I found it uncommon on Mt. Karimui (5,100-8,100 ft) and Mt. 
Michael (7,000-8,000 ft) and never saw it in the Okapa area, whereas 
Bulmer found it very common on Mt. Hagen and the Schraderberg. 
I observed individuals or groups of two or three 10-70 ft above the 
ground, prying in thick moss on trunks, or abruptly hopping up 
branches and vertical trunks, remaining stationary between hops. ‘The 
long tail is flicked to the side as the bird turns, and looks as if it is 
about to fall off. The convulsive flight consists of rapid flaps alter- 
nating with a glide. 

VOICE. I heard only a single quiet, harsh, frog-like note. In Gil- 
liard’s experience as well it seems to have been one of the quieter 
birds of paradise. 


Lophorina (Astrapia) mayeri (Stonor)} 
Ribbon-tailed Astrapia 


The range of L. mayer extends eastward to Mt. Hagen and Giluwe, 
where Gilliard, Shaw-Mayer, and Bulmer found it plentiful to abun- 
dant at 8,000-10,000 ft. As discussed by Mayr and Gilliard (1952a), its 
geographical range overlaps that of L. stephaniae on Mts. Hagen and 
Giluwe, where hybridization occurs to a limited extent (Shaw-Mayer, 
fio) Sis, ISG, py 420). 

A point of particular interest is that on both Mts. Hagen and Gil- 
uwe, astrapias at lower altitudes are apparently pure L. stephaniae or 
hybrids closest to it, while those at higher altitudes are pure L. mayeri 
or hybrids closest to it. The transition altitude is at 8,000-8,500 ft, 
as shown by Shaw-Mayer’s observations on Mt. Giluwe and Bulmer’s 
and Gilliard’s on Mt. Hagen. The geographical ranges of L. mayeri 
and L. stephaniae are still largely allopatric and overlap only in this 
limited area. These two species thus illustrate the earliest stage in the 
evolution of two allopatric members of a superspecies group into 
sympatric species with mutually exclusive altitudinal ranges (p. 22, 


1 Listed as Astrapia mayeri in Rand and Gilliard (1967).

SPECIES ACCOUNTS 


p. 34). The western limit of L. mayeri, where it is replaced by L. 
splendissima, must lie somewhere between Mt. Giluwe and ‘Telefolmin 
and provides one of the major unsolved distributional problems in the 
western part of the Eastern Highlands. As at the eastern limit, the 
details of the transition may prove of interest. 


Lophorina (Pteridophora) alberti (Meyer)! 
King of Saxony Bird of Paradise 


NATIVE NAME. Fore: warale. 

SPECiMENS EXAMINED. Miarosa: 1 imm. ¢ (24 June 1964). 

WING. “19: 

TAXONOMY. The specimen is largely in female-like plumage but 
has scattered velvet-black patches on the crown and orange on the 
breast. 


BREEDING. ‘The testes were enlarged. 


DISCUSSION. Although two races of this species (buergersi and 
hallstromt) have been named on the basis of differences in female 
plumage, reexamination of available material, including the type 
and three paratypes of hallstromi (Mt. Hagen) and two nearly topo- 
typical specimens of buergersi (Schrader Range, 50 miles from Mt. 
Hagen) shows that the variation is irregular and probably too slight 
to warrant taxonomic recognition. ‘The only differences worth men- 
tioning are that the ventral barring is slightly heavier in the Snow 
Mountains, and slightly more widely spaced in the Eastern Highlands, 
than in the Weyland Mountains (albertt), and that the measurements 
are slightly larger for the Wahgi population (average wing length of 
females: Wahgi region, 116.0 mm (range, 8 ¢@, 107-122.5); Schrader 
Range, 111.3 (4 ¢, 109-113); Snow Mountains, 113.2 (9 ¢, 110-115); 
Weyland Mountains, 112.2 (6 ¢@, 110-114)). Gilliard and LeCroy (1968, 
p. 26) already noted that the female which Gilliard collected in the 
Schrader Range (the type locality of Rothschild’s race buwergerst) is 
indistinguishable from some Wahgi specimens, which had been sep- 
arated from buergersi as hallstromi. The trivial differences on which 
collectors have often founded subspecies of birds of paradise have 
obscured a biologically important and still unexplained fact, namely, 
that geographical variation within many species of birds of paradise 
is remarkably slight compared to the striking differences between dif- 
ferent semispecies or species. 

The King of Saxony Bird of Paradise is widely but unevenly dis- 
tributed in forest between about 6,000 and 9,000 ft. On Mt. Michael 
an adult male was observed “‘singing’”’ from a perch 30 ft above the 
ground at 7,800 ft. On Mt. Karimui two adult males “sang” regularly

6,200" ft. 

VOICE. “The “song” lasts about 3 sec, gradually increases in vol- 
ume, and has such a weird quality that one is unlikely to suspect a 
bird as the author. It is a very dry rattling, a spitted jumble of 
insect-like notes poured out at a machinegun pace and suggestive of 
bad static on the radio, which briefly turns into a twittering at the 
climax of the crescendo. 


Paradisaea raggiana salvadorii Mayr and Rand

TAXONOMY. ‘The male specimen is not yet fully adult and has 
tail wires 410 mm long but no flank plumes. Birds from the Karimui- 
Okapa area as well as those from the Wahgi Valley are pure P. rag- 
ginan salvadoru and show no approach to P. apoda novaeguineae of 
the middle Fly River (whitish flank plumes, nape maroon rather than 
yellow) nor to P. r. raggiana of southeastern New Guinea (upper back 
yellow). 

BREEDING. Gonads were small in almost all birds examined. 


DISCUSSION. Paradisaea raggiana is common in the Eastern 
Highlands up to a ceiling varying locally between about 4,500 and 
5,600 ft. At the so-called Hybrid Gap at the western end of the Wahgi 
Valley, where the pass between the Baiyer River drainage of the 
northern watershed and the Wahgi drainage of the southern watershed 
has been deforested, Paradisaea raggiana has been able to cross into the 
Baiyer Valley and hybridize with P. minor, according to Blood (cited 
by Mayr and Gilliard, 1954, p. 321) and information given to Bulmer 
by native informants. It is considerably more numerous in ecologically 
disturbed areas (casuarina groves, second-growth, and the forest edge) 
than in the forest interior, and its unusually high ceiling in the Eastern 
Highlands and its invasion of the northern watershed have probably 
resulted from native agriculture. 

Fully plumed adult males were very rare in my study areas, un- 
doubtedly due to native hunting pressure. Even subadults with tail 
wires but no flank plumes were encountered only twice. That the 
species nevertheless remains common in settled areas is probably due 
to subadult males with none of the prized ornamental plumage regu- 
larly mating with females in the absence of fully adult males. The 
birds remain in the middle- and upperstory (none was netted), and 
were often associated in noisy groups of a half-dozen. ‘Verborgh re- 
corded P. raggiana both in fruiting trees and flowering trees in the

Karimui area. The characteristic flight consists of several convulsive 
flaps followed by a brief soar. 

VOICE. The common call is a series of a dozen or more loud 
“caw’s” which progressively rise in pitch and decelerate. Often this 
series concludes with two more “caw’s’” at lower pitches and longer 
intervals (Fig. 35).

DISCUSSION. ‘This is the northern watershed equivalent of P.

P. minor common in settled areas of Kyaka territory up to 5,500 ft, 
though fully adult males were as seldom seen as in the case of P. rag- 
giana and presumably for the same reason. 

VOICE. A series of loud “caw’s” very similar to the call of Para-

TAXONOMY. In females and immature males of the race marga- 
ritae, originally described from the Wahgi Valley, the underparts, in- 
cluding the central belly and flanks, have black barring, whereas 
rudolphi of southeastern New Guinea has only the lower belly dis- 
tinctly barred and the chest only faintly barred. ‘The Karimui specimen 
is as barred as margaritae and is assigned to it. One of the Awande 
immature males is barred but more obscurely, and the other Awande 


341 


SPECIES ACCOUNTS 


immature and the unsexed bird have as little barring as rudolphi, so 
that the more easterly Awande population is nearer rudolphi. ‘The 
adult male from Awande is indistinguishable from rudolphi. 


DISCUSSION. ‘The Blue Bird of Paradise lives in forest between 
about 3,600 and 6,500 ft and is generally uncommon. ‘The population 
structure apparently follows the usual pattern, with adult males seen 
and calls heard only in the upper parts of the altitudinal range. 
Unlike P. raggiana and P. minor, it has not been able to colonize 
second-growth extensively and hence has been driven from much of 
its range by native agriculture (some of Bulmer’s records, however, 
came from the forest edge and nearby garden areas). In undisturbed 
forest the altitudinal range of P. rudolphi lies largely or wholly above 
that of P. raggiana, as also true for P. guilielmi vis-a-vis P. minor on 
the Huon Peninsula. The western limit of the geographical range of 
P. rudolphi in the western part of the Eastern Highlands remains to 
be determined. 


VOICE. The call pointed out to me by natives consisted of a 
series of notes somewhat similar to the call of Paradisaea raggiana, but 
with longer intervals between the notes, successively lower pitches, 
and a bell-like quality. The resemblance of each note to the syllable 
“kong” is the origin of the Fore name “kongonamu”. 


PTILONORHYNCHIDAE: BOWERBIRDS 


Archboldia papuensis sanford: Mayr and Gilliard 
Archbold’s Bowerbird 


This extremely local bowerbird is known only from a small area 
between 8,500 and 9,000 ft on the southwestern slope of Mt. Hagen, 
where Gilliard and Shaw-Mayer collected it, and between 8,500 and 
9,000 ft on Mt. Giluwe, where Shaw-Mayer collected it. Neither Bul- 
mer nor Gilliard found it on the northern slopes of Mt. Hagen, and 
Bulmer’s native informants from the southeastern slopes said that 
it occurred only farther west.

‘The crests of both my adult male specimens are a deep orange com- 
parable to that of the much shorter crest of A. swbalaris, and darker 
than in any of the available museum specimens of A. macgregoriae, 
which have a paler and yellow-orange crest. 

DISCUSSION. Amblyornis macgregoriae is widespread, though 
uncommon, in forest from 9,000 ft down to a lower limit varying 
locally between 3,500 ft (Okasa) and 5,200 ft (Mt. Karimui). One bower 
was found at about 6,800 ft in forest in the Okapa area, while there 
were four bowers on the west ridge of Mt. Karimui, all on the flat 
crest of the ridge: two within a few feet of each other at 5,390 ft, one 
at 5,820 ft, and one at 6,060 ft. An immature male in female plumage, 
with tiny testes and no trace of a crest, was collected while working on 
a bower. 

I spent two mornings observing from a blind at one of these bowers 
(Fig. 36). It was located on a broad, flat, ridge crest, and was con- 
structed around a sapling 16 ft tall and 3/4 inches in diameter. Sticks 
were criss-crossed about the trunk of the sapling to 8 ft above the 
ground, subtending for the most part 1 ft, occasionally up to 2 ft. 
Above 8 ft the sapling had branches with leaves, but below this height, 
where the sticks were criss-crossed, there was only one leafless branch 
(the bird probably having stripped the leaves) and a vine from an 
adjacent tree with a few leaves. About the base of the sapling the bird 
had constructed a circular moss platform 54 inches in diameter, with 


343 


SPECIES ACCOUNTS 


a raised rim around the periphery surrounding a moss basin 5 in deep 
and 30 inches in diameter. In the center of the basin a moss base 10 
inches in diameter rose immediately about the sapling. Outside the 
platform was a small pile of chips of black, burnt wood. ‘The surround- 
ing forest was tall and open, with some particularly large Araucaria 
cunninghamii. Most of the bower was in shade, though some sunlight 
reached the bower floor. 

On the first day both a crested adult male and a bird in female 
plumage were in the vicinity when I arrived at 10:20, and the birds 
moved about within 30 ft of the bower. The female never actually 
came to the bower nor within 10 ft of the male and perched between 
12 and 35 ft above the ground. The male appeared squat and short- 
tailed with his center of gravity and much of his body apparently well 
forward of his legs. His orange crest remained inconspicuous, the base 
concealed, only the distal part visible. While perched, he seemed to 
peer intently, and his movements as he suddenly turned on his perch 
or suddenly flew off with a loud wing beat were ludicrously abrupt. 
Until 10:40 he assumed various perches 4-15 ft above the ground but 
not at the bower and was silent except for some kissing and scolding 
notes. Eventually he approached the bower, giving soft, downslurred, 
whining notes and rapidly repeated scolding notes. From 10:40 to 
10:46 he stood around the base of the bower and continued to make 
whining and scolding sounds. Until 11:01 he periodically appeared 
and reappeared 20 ft from the bower, perched 4-15 ft above the ground, 
and once hopped vigorously up the trunk of a 2 inch sapling to a 
height of 15 ft. Between 11:01 and 11:06 A.M., when observations 
were terminated, no birds were visible. 

On the next day I arrived at 09:28, placed 20 dead leaves on the 
moss basin to see what the bird would do with them, and went into 
the blind. At 09:30 the male appeared with a rustle of wings, and re- 
mained in the vicinity until 10:58 without the female. At first he 
took up various perches 15 ft or more from the bower, once perching 
sideways on a vertical sapling like a thicket flycatcher. At 09:47 he 
gave nasal downslurred calls like a Melidectes honeyeater; at 09:49, 
neighed like a horse; and at 09:51 gave a call like the crack of a 
bushknife striking a tree. Finally, at 09:57 he alighted on the rim of 
the bower with white moss or lichens in his bill, occasionally turning 
his head. After a minute he picked up one of the dead leaves I had 
left in the basin and dropped it on the rim, carried another leaf 3 ft 
off, and threw two over the rim with a toss of his head. He then spent 
a minute on the ground just outside the rim, during which he briefly 
raised, flared, and exposed his whole orange crest, which was otherwise

turned to the bower at 10:06. This time he threw out the leaf he had 
previously dropped on the rim, then threw out some smaller leaves 
by carrying them to the rim and tossing them several inches outside,

and at 10:07 picked up the largest leaf and flew off with it. In 26 min 
he appeared again briefly, and at 10:40 reappeared with a whirring of 
the wings and perched 2 ft up on a vertical sapling behind the bower. 
He rapidly shifted perches to different saplings several times, quickly 
opening and closing his wings while perched. At 10:44 he flew off 15 ft 
to a perch 7 ft up and remained stationary for 3 min, during which he 
once again raised and flared his crest. After another shift of perch he 
began quiet, broken, nasal downslurs, coughing sounds, and chirps 
for 5 min. The sounds stopped at 10:58, and he remained away until 
at least 11:30, when I left. There were still 12 dead leaves remaining 
in the bower. 

Paran found a nest with one nestling near the bower, 7 ft up in a 
pandanus. It was a bowl 5 inches deep and 51% inches in diameter, 
lined with small twigs, and woven of strips of dry blades 3/4 inch broad 
and 1-2 ft long brought from the adjacent grassland, plus a few dry 
pandanus leaves and Castanopsis leaves. In Paran’s experience, the 
nests of Amblyornis macgregoriae generally contain one nestling, which 
is fed by the female alone.

Iredale (1948) lists a skin from an unspecified locality in the Mt. 
Hagen district. This probably originated from somewhere in the Fly- 
Strickland-Kikori drainages and reached the Mt. Hagen district by 
native trade routes. There are no authentic records from the Eastern 
Highlands.

BREEDING. A female brought in at Okasa by a native had en- 
larged ovaries. 


DISCUSSION. ‘This grassland bowerbird was present at Okasa

WEIGHT. 205. 

WING. 152. 

TAXONOMY. Specimens of melanocephalus from southeastern 
New Guinea vary somewhat in the darkness of the underparts, and 
the Mt. Karimui bird agrees with the darker specimens. ‘he race 
melanotis of southern New Guinea is paler and greener below, while 
guttaticollis of the Sepik Mountains, to which Gyldenstolpe assigned 
with reservations a single specimen from the Jimmi River (northern 
watershed), has buffer spotting on the crown and nape. 

BREEDING. ‘The testes of the specimen were very small. 

DISCUSSION. ‘The altitudinal ranges of A. crasstrostris and A. 
buccoides are mutually exclusive. In most areas of New Guinea the 
transition takes place around 2,500 ft, but in the Karimui area it is 
around 4,000 ft because of tropical conditions in the Karimui Basin. 
I found A. crassirostris between 4,300 and 5,450 ft on Mt. Karimui and 
also at Okasa. My observations were of solitary individuals in the 
middlestory of the forest (at least 20 ft above the ground), where their 
movements were easily traced by the calls. However, the single speci- 
men was netted, probably a victim of its habit of eating birds and 
bats trapped in nets. 

VOICE. A peculiar, not loud, mewing sound “wa-a-a-a-a-a” which 
lasts 114 to 2 sec and is repeated at 10- to 15-sec intervals. Each note 
fluctuates up and down in pitch a few times within a span of about 
two whole tones.

though the darkest stonii are comparable. There is good agreement 
in the small size of the spots on the underparts and their sparseness on 
the abdomen. The races oorti, geislerorum, and buccoides all have 
much paler crowns, geislerorum and oorti have much paler under- 
parts, and the spots on the underparts are larger in oorti and buccoides. 
Gyldenstolpe assigned a single specimen from the northern watershed 
to geislerorum, while Schodde and Hitchcock placed the Lake Kutubu 
population with cinnamomeus. 

BREEDING. Gonads were small in all individuals examined in 
1965, and were enlarged in one male and one female and small in the 
other male in 1964. 

DISCUSSION. In the Karimui region Ailwroedus buccoides was 
rarely seen but frequently netted because of its habit, shared with 
A. crassivostris, of eating birds trapped in mistnets. The head of the 
victim was always eaten, and sometimes other parts as well. 


NEOSITTIDAE: AUSTRALIAN NUTHATCHES 


Daphoenositta miranda kuboriensis Mayr and Gilliard 
Pink-faced Nuthatch 


DISCUSSION. ‘This nuthatch of high-altitude moss forest has 
been recorded four times in the Eastern Highlands at 8,000-10,000 ft: 
in the Kubor Mountains by Gilliard, in the Lamende Range by Shaw- 
Mayer, and in the Schrader Range by Gilliard and by Bulmer. Its 
habits, and those of Neositta chrysoptera, seem to me more like those of 
a warbler than of Sitta. Its progress is neither systematic nor slow; it 
spends only a few minutes in a tree before flying off, usually out of 
sight. It hops rapidly along a branch of either a dead or a leafy tree 
at about 1 ft per sec, leaning over and peering first to one side then 
another, and flits off to another branch. While it occasionally clings 
to the underside of a horizontal branch or goes up a vertical one, much 
more often it remains on the upper side of horizontal branches. I 
watched one digging and pounding repeatedly in bark, another shak- 
ing and eating a 3 cm grub. It was always in flocks, of three to five 
birds. 

VOICE. Faint, sweet, sucked-in, slightly squeaky contact calls 
which are louder in flight than when perched; and a faint chatter 
when two individuals came together.

TAXONOMY. My three specimens have the whole head and 
upper breast pure white except for a few brown streaks on the chin 
and crown of the male, and the white markings on the inner edge of 
the primaries are more prominent than in any other New Guinea 
examples of the species available for comparison. Four birds which I 
observed in the Karimui area also had the whole head white. 

The three geographically nearest races are alba of the Idenburg 
slopes (male with the whole head white, female unknown), toxopeusi 
of the Snow Mountains (male with the head and neck streaked, female 
apparently with the head and neck white), and albifrons of south- 
eastern New Guinea (male with more dark areas and streaking on the 
head, female with a whitish head with brown shaft streaks). White 
spotting as on the primaries of the Miarosa specimen is present but 
reduced in albifrons, toxopeusi, and papuensis and is nearly absent in 
alba. Descriptions of three other Eastern Highlands adults have been 
published: a single white headed adult male collected by Shaw-Mayer 
at 8,000 ft on Mt. Giluwe, which Sims (1956, p. 430) found to match 
alba; a single adult male collected by Gilliard at 8,300 ft on Mt. Hagen, 
which is in general intermediate between albifrons and toxopeust 
except for lacking the primary spots, and which Mayr and Gilliard 
refrained from identifying subspecifically; and a single adult female 
collected by Gyldenstolpe at Nondugl, which was nearest toxopeusi 
but had more dark areas on the head and which he described as a 
new race, wahgiensis. Descriptions of one specimen collected by 
Bulmer at ‘Tari, one collected by Blood at Wabag, and five collected 
by Hitchcock in the Kubor Range had not been published at the time 
of writing. In view of the individual variation among the Eastern 
Highlands specimens collected to date, it is not possible to assign the 
material or to evaluate the validity of wahgiensis until an adequate 
series can be compared with adequate series of the other races (alba 
and toxopeusi are each known from only four specimens). 

DISCUSSION. ‘This species may be the middle-altitude equivalent 
of Daphoenositta miranda. 1 observed small flocks at 8,000 ft on Mt. 
Michael, at 6,000 ft in Gimi territory, and at logoramalu (3,630 ft) in 
the Karimui Basin, in addition to collecting the Miarosa (6,800 ft) 
and Awande (6,000 ft) specimens. These flocks were in tall trees with 
little foliage in forest clearings and gardens. Each flock spent a few 
minutes at one tree and then moved on as a group with undulating 
flight to a neighboring tree or else out of sight. As they worked actively 
over a tree, they frequently crawled on the undersides of branches, 
hung upside-down from branches, or else assumed upside-down. posi- 
tions on vertical trunks. Paran said that Neositta chrysoptera disappears 
from the Okapa area during the rainy season.

STOMACH CONTENTS. Principally insects, occasionally fruit. 

DISCUSSION. ‘The Black Sunbird was common at Soliabeda, and 
rare at Karimui, at the forest edge and in gardens and second-growth. 
‘The Karimui records are much higher than the species normally occurs 
elsewhere in New Guinea. Schodde and Hitchcock also found the 
Black Sunbird at Lake Kutubu (2750 tt). It perched) ims treetops; 
hovered in hummingbird fashion at flowers, probed while hanging 
upsidedown, or alighted on fallen logs and fences in gardens, moving 
rapidly and seldom remaining in one place for long. It fed on the 
surface of vegetation, never inside the forest. 

VOICE. ‘There are a variety of common calls, all very high-pitched, 
thin, sibilant, and rather faint. Common patterns are a rapid series of 
identical upslurs; one or several upslurs followed by a slow trill at a 
lower pitch; a breezy, slower upslur like North American goldfinches 
(Carduelis sp.); and a rapid series of notes alternating between two 
different pitches (Fig. 37). Some of these calls are similar to those of 
the honeyeater Conopophila albogularis, and others to the calls of the 
flowerpecker Dicaeum geelvinkianum, another tiny black bird of the 
treetops.

TAXONOMY. The four races of this species were separated on 
the basis of trivial differences in color shades. The Vogelkop popula- 
tion (nominate fulvigula) has the olive of the back slightly duller and 
darker, and the throat and breast browner, than the population of the 
Central Range (meyeri). The population of the Snow Mountains is 
much too similar to the southeastern New Guinea population to 
warrant the name montana (type and two paratypes from Mt. Goliath 
examined). The fourth race, fuscicapilla, is also probably a synonym 
of meyeri. 

‘The iris was orange in all specimens. 

BREEDING. ‘Testes were enlarged in the Mt. Karimui males. 


DISCUSSION. .The Awande specimen came from 6,200 ft, the 
Mt. Michael ones from 8,000 ft, and the Mt. Karimui ones from 5,780 
to 6,500 ft. Four of the six specimens were netted, suggesting under- 
story habits, in agreement with the observations of Stein (1936, p. 30). 
This species does not use flowering trees. Other Eastern Highlands 
records are one specimen each from the Wahgi Region (Gilliard) 
and the Schrader Range (Bulmer).

SPECIES ACCOUNTS 


obtrusive tropical species ranging up to 5,000, rarely 6,000 ft. In the 
Karimui area, where it accounted for 1-2% of the local avifauna, the 
usual change in sex ratio with altitude is apparent: females predomi- 
nate at the two lower stations (Solhabeda and Bomai), males at the 
two higher stations (Karimui, Mt. Karimui). In habits this is a solitary, 
shy, slow-moving, and silent bird of the lower- and middlestory (up 
to about 30 ft above the ground) in forest and second-growth. Propor- 
tionately more of the specimens were taken in nets at Soliabeda and 
Bomai than at Karimui, and still fewer were netted on Mt. Karimui. 
Since the Mt. Karimui specimens were mostly males in breeding con- 
dition, they may spend less time in the lowerstory. M. megarhynchus 
tended to feed by working its way up a tree, gleaning (presumably for 
insects) close to the trunk and branches. It also came to flowering trees. 
‘Terborgh observed a few individuals in a tree with small fruits at 
Mengino and in the tree at Miarosa with hard-shelled fruits chipped 
open by parrots (see under Trichoglossus haematodus, p. 143). 

VOICE. A harsh but quiet downslur “chur-r-r’’ or mewing sound 
is occasionally given. 


Niche Differences in the Genera Toxorhamphus and Oedistoma 


The genus Toxorhamphus has usually been considered to consist 
of three very similar species, T. poliopterus, T. novaeguineae, and T. 
tliolophus. However, I concur with the decision of Salomonsen (1967, 
p- 342) to remove zliolophus to the genus Oedistoma, formerly con- 
sidered monotypic (O. pygmaeum). 

The niche differences among these ecologically similar honey- 
eaters are as follows. T. poliopterus and the very similar T. novae- 
guineae live mainly in the understory and do not visit flowering 
trees. Their altitudinal ranges are mutually exclusive (7. polio- 
pterus at higher altitudes than T. novaeguineae) where both occur, 
and the former descends much lower in the absence of the latter. T. 
novaeguineae has not been recorded from the Eastern Highlands and 
is probably absent on the southern watershed east of the Fly River 
but should turn up below 4,000 ft on the northern watershed, where 
Gilliard collected it at the foot of the Schrader Range. The similar- 
sized O. iliolophum, in addition to foraging in the understory, also 
ranges into the treetops and visits flowering trees, which T. poliopterus 
and T. novaeguineae never do in my experience. O. pygmacum is 
similar in habits to O. iliolophum but spends even more time in 
flowering trees and less time in the understory, weighs slightly less 
than half as much, and has a relatively shorter bill. O. pygmaeum and 
O. iliolophum range infrequently down to sea level, T. poliopterus 
never. O. pygmaeum has the lowest altitudinal ceiling, O. iliolophum 
higher, and T. poliopterus the highest.

TAXONOMY. ‘Table 14 summarizes measurements for populations 
from the eastern half of New Guinea. The first four entries, pertaining 
to my Eastern Highlands specimens, or else the second through fourth, 
pertaining only to the Karimui area, show a significant increase in bill 
length and wing length with altitude. ‘There also appears to be some 
local variation in the bill-to-wing ratio (compare ratios for Nondugl, 
Mt. Karimui, and Awande, within 80 miles of each other and at similar 
altitudes). Greenway (1935, p. 98) pointed out that there is a wide 
range of variation in bill length and crown color (more gray or more 
green) in specimens from a given locality. Huon Peninsula birds were 
separated from southeastern New Guinea birds (nominate poliopterus) 
as septentrionalis on the basis of a shorter bill, slightly longer wing, 
lower bill-to-wing ratio, and more greenish, less pure gray crown 
(Mayr and Rand, 1935, p. 14). ‘This race may be insufficiently distinct 
to merit recognition. ‘he average difference in the color of the crown 
is slight, though detectable; the average difference in the culmen shown 
by ‘Table 14 is slight; and the difference in wing length shown in ‘Table 
14 is difficult to evaluate without better knowledge of the altitudes 
at which the specimens were collected, since both the Huon Peninsula 
and southeastern New Guinea series fall within the range of averages 
for Eastern Highlands populations at various altitudes. On the basis 
of the average color of the crown (virtually the same as in southeastern 
New Guinea) and the bill-to-wing ratio, Eastern Highlands birds would 
have to be considered nominate poliopterus rather than septentrionalis, 
if septentrionalis were recognized. ‘The race maximus of western New 
Guinea has a darker crown, and perhaps larger dimensions. 

BREEDING. All ovaries were small, but testes at most localities 
were enlarged. ‘The main exception was the small testes of Soliabeda 
males, suggesting that, as usual, immatures or nonbreeding birds are 
concentrated at the bottom of the species’ altitudinal range. 

DISCUSSION. The altitudinal range of T. poliopterus is roughly 
1,500-6,000 ft, but both the lower limit and the ceiling show marked 
variation. ‘The variations in the lower limit are correlated with the 
presence or absence of the related T. novaeguineae, which occurs from

sea level to about 4,000 ft in western New Guinea, extending east 
through the Sepik Basin on the northern watershed but only as far as 
the Fly River on the southern watershed. Where the two species are 
sympatric, T. poliopterus does not descend below 4,000 or 5,000 ft 
(Sepik Mountains, Snow Mountains, Weyland Mountains, and pos- 
sibly the northern watershed of the Eastern Highlands). Where 1. 
novacguineae is absent, T. poliopterus descends to about 1,500 ft 
(southeastern New Guinea, southern watershed of the Eastern High- 
lands at Soliabeda, and possibly Herzog Mountains and Huon Penin- 
sula). The variations in the ceiling depend upon the local elevation 
of the moss level, so that the ceiling was lower on Mt. Karimui (5,800 
ft) than in the Okapa area (up to at least 6,800 ft) and still higher on 
Mt. Michael (8,100 ft). 

Within its altitudinal range, particularly in the upper part of its 
range, T. poliopterus is among the most abundant forest birds, some- 
times the most abundant species (e.g., 99% of the local population at 
4,000-5,600 ft on Mt. Karimui). One would never guess this, however, 
without nets or knowledge of the song, since the bird is infrequently 
seen. Its habitat is the forest interior, forest edge, or second-growth. 
It may be seen up to 30 ft above the ground but concentrates in the 
lowerstory, as evidenced by the numbers in which it saturated our 
mistnets (see under Oedistoma pygmaeum for further discussion of 
its habits). It darts about rapidly in the undergrowth, pecking at 
branches and sometimes hanging upside-down. 


VOICE. Vocalizations are varied, frequent, weak, similar in quality 
to the calls of the sunbirds Nectarinia sericea and N. jugularis, and 
fall into two categories. Some calls have a dry quality, such as a dry 
squawk, a dry scolding, and a disyllabic sneeze-like note; but most 
have a sweet quality. The commonest call is a sweet “‘tsip’; another 
is “tsee-tsee-tsee-tsee-tsee’. ‘The songs with sweet quality consist of 
slurs, disyllabic notes, and repeated notes (Fig. 38). One of these songs 
resembles a weak version of the song of Meliphaga auga and may be 
confused with it.

TAXONOMY. The flanks are more brightly lemon-colored than 
in nominate liolophus. The wing lengths of both the Okasa specimens 
(2 6, 68 and 70) and of the remainder from the Karimui area agree 
with southeastern New Guinea birds (3 66-70, 9 62-64) and are larger 
than on the Fly River (4 63-67, 9 58-62). 

BREEDING. Gonad condition varied from small to moderately 
enlarged. 


DISCUSSION. O. iliolophum was present at all my collecting 
stations up to 5,125 ft, and at none above this altitude. It was com- 
monest at Karimui (3,650 ft), much less common at Soliabeda (2,000 ft), 
and is either absent or quite uncommon in flat country at sea level 
(as with many hill forest species, this last statement does not apply 
to the flat lowlands of the Fly River basin). 

O. iliolophum and Toxorhamphus poliopterus have nearly the 
same wing length; O. tlolophum weighs slightly more; and T. 
poliopterus has a considerably longer bill (culmen from base ca. 
30 vs. ca. 20 for O. iliolophum). ‘T. poliopterus has brighter colors, 
but the coloration of O. iliolophum is sufficiently similar that field 
identification is usually difficult. There is broad altitudinal overlap 
from 1,500 to 5,000 ft, with 7. poliopterus extending above and O. 
tliolophum below these limits. However, there are two striking niche 
differences. First, in flowering trees we never saw T. poliopterus but 
regularly saw O. tliopholum, which accounted for 1.39% of the bird- 
usage in flowering trees at Karimui. The other difference involves 
netting returns: nets accounted for 57°% of our specimens of O. zliolo- 
phum but 88% of our specimens of 7. poliopterus. Evidently both 
species spend much time in the understory, but the tendency is de- 
veloped to an extreme degree in T. poliopterus. In flowering trees 
O. iliolophum was seen as often in the upper half of the tree (includ- 
ing the canopy) as in the lower half. It was also frequently seen 
within 10 ft of the ground (as one would suspect from the netting 
returns) and had a particular affinity for the clusters of small wild 
bananas at Karimui. Its behavior was often nuthatch-like, feeding 
close to branches and perching upside down on tree trunks and banana

clusters. However, it also hovered at the banana clusters, like a sun- 
bird (to which it bears a striking superficial resemblance) or a hum- 
mingbird. 


Oedistoma pygmaeum pygmaeum (Salvadori) 
Pygmy Honeyeater

WEIGHT: Tf gPo0: 179? 5.7. 

WING. 1 4: 48. 1 9: 47. 

TAXONOMY. Ina paper preliminarily naming a total of 28 races 
of meliphagids, based on reexamination of older material, Salomonsen 
(1966) described three new races of O. pygmaeum. ‘The birds collected 
by Stevens on the Watut River in 1932 and already analysed by 
Greenway were described as olivascens: “Very similar to nominate 
pygmaeum but under parts with a conspicuous grayish olivaceous 
tinge and upper parts slightly darker’ (Salomonsen, 1966, p. 2). Ex- 
amination of the type series shows that the type (a male) stands out 
obviously among the eight males collected by Stevens as having the 
least yellow belly and lower flanks. Apart from this individual variant, 
Stevens’ series is not distinguishable from other New Guinea popula- 
tions. The name flavipectus was proposed for southern New Guinea 
birds, with the type a bird collected by Rand in 1934 on the First 
Archbold Expedition and already analysed by Mayr and Rand. 
Southern New Guinea birds do average a shade paler above and 
yellower below than the Vogelkop and northwestern New Guinea 
population, but many specimens can be matched, and the average 
difference is too slight for recognition. 

DISCUSSION. ‘The Pygmy Honeyeater occurred from about 2,000 
to 4,500 ft. It was commoner than the two specimens indicate, and 
gathered in flowering trees, where it often accounted for 10 to 30% 
of bird-usage and was twice as common in the upper half as in the 
lower half of the crowns. In flocks of up to 10 it called incessantly and 
was in constant motion. One was seen to hover. ‘The tailless silhouette 
(the tail extends no farther than the wings) is confusable only with 
Gerygone warblers, from which the hypernervous and social behavior 
and the voice serve to identify it. 

VOICE. A constant, weak, rapid train of spitted notes on the same 
pitch. 


Niche Differences in the Genus Myzomela 


The five members of this genus contribute heavily to the bird-usage 
of flowering trees in New Guinea (Terborgh and Diamond, 1970). 
Apart from the erratically distributed second-growth species M.

SPECIES ACCOUNTS 


adolphinae, the only form above 5,000 ft is M. rosenbergu. ‘Three 
species (M. cruentata, M. nigrita, and M. eques) occur at lower allti- 
tudes, and at Karimui these three plus M. rosenbergii were present 
and often seen in the same tree. At Soliabeda M. nigrita, M. cruentata, 
and M. eques fed in the same tree, while M. nigrita, M. cruentata, and 
M. rosenbergii fed together at the Sena River. M. nigrita, M. cruentata, 
and M. rosenbergii are very similar in size and habits, confining them- 
selves to the top of the canopy to an even more marked degree than 
does Oedistoma pygmaeum. Among the three species of myzomelids 
at lower altitudes, M. eques sorts out ecologically on the basis of its 
larger size (twice as heavy as M. nigrita and M. cruentata), presence 
at sea level (where M. nigrita and M. cruentata are rare or absent), and 
less extreme tendency to stay in the treetops. M. nigrita and M. 
cruentata are very similar ecologically, and the only difference I have 
noticed is that the altitudinal range of M. cruentata lies on the 
average higher.

TAXONOMY. ‘This is another of the dark races from Karimui 
(Diamond, 1967a, p. 9). 


BREEDING. ‘The gonads of the unique type were somewhat 
enlarged. 


DISCUSSION. Of the five myzomelids in the Eastern Highlands. 
M. eques is the largest (in the male) and is the only one to extend 
regularly down to sea level. It was present at Soliabeda (2,000 ft) as 
well as Karimui (3,650 ft) but not at any higher station. ‘Verborgh’s 
observations at Karimui show that it accounted for 1-7% of the bird- 
usage in flowering trees and was consistently several times less numer- 
ous than M. nigrita but more numerous than M. cruentata or M. 
rosenbergit. A possible indication of niche specialization among 
myzomelids is provided by ‘Terborgh’s observation that M. eques, 
although mainly a canopy species, spent about one-third of its time 
in the lower half of the crown, whereas M. cruentata and M. nigrita 
were virtually confined to the upper half of the crown. In addition, the 
larger M. eques is somewhat slower moving than M. cruentata, M. 
nigrita, or M. rosenbergit.

Myzomela adolphinae Salvadori 
Mountain Red-headed Myzomela 


DISCUSSION. ‘This myzomelid of second-growth, open country, 
and gardens between 4,000 and 6,400 ft varies radically and unpre- 
dictably in its abundance from place to place and from time to time, 
perhaps due to local movements associated with flowering of trees. 
Eastern Highlands records are from Kyaka territory and the Baiyer 
Valley (Bulmer), Nondugl (Gyldenstolpe, Shaw-Mayer), and the Kubor 
Mountains (Gilliard, Hitchcock). This species is present in the Vogel- 
kop and Eastern Highlands but absent in the entire western half of 
New Guinea outside the Vogelkop, a distribution shared only by 
Zosterops novaeguineae. I have seen a singing male M. adolphinae 
and a male M. rosenbergii in the same tree. 


VOICE. ‘The song, repeated at 4 sec intervals, is suggestive of an 
Empidonax flycatcher (Tyrannidae, North America). It consists of two 
high-pitched notes, the first higher than the second, the first often 
upslurred, the second often trilled. The song of Myzomela sclateri 
is very similar.

BREEDING. ‘The gonads were greatly enlarged in three of the

DISCUSSION. ‘The Red Myzomela was observed at Soliabeda 
(2,000 ft), Karimui (3,650 ft), and the Sena River (4,500 ft). In flowering 
trees at Karimui and Soliabeda it accounted for 1-4% of the bird- 
usage and was much less numerous than M. nigrita or M. eques. At the 
higher altitude of the Sena River M. eques was absent, M. nigrita 
very uncommon, and M. cruentata and M. rosenbergit equally common 
(16% of the bird-usage each). Like M. nigrita, M. cruentata is vir- 
tually confined to the top of the canopy. The only ecological difference 
I can observe between these two species is that the altitudinal range 
of M. cruentata is centered slightly higher (M. nigrita commonest at 
1,500-3,500 ft, M. cruentata commonest at 2,500-4,500 i)

for a small rose area on the chin.

somewhat in two, at Karimui (3,650 ft); not enlarged in the two from

mature males, not in the other, at Karimui. 


DISCUSSION. In flowering trees at Karimui and Soliabeda this

other three species combined. On the average, it accounted for 10% 
of the bird-usage. At the Sena River it was much less common than 
M. cruentata and M. rosenbergiu and accounted for only 1% of the 
bird-usage. Like M. cruentata, M. nigrita is a canopy species: out of 77 
individuals whose position in the upper or lower half of the tree was 
noted, 73 were in the upper half.

TAXONOMY. Gyldenstolpe (1955, p. 155) separated Eastern High- 
lands birds (wahgiensis) from nominate rosenbergii of the Vogelkop. 
However, comparison of my adult males with adult males collected 
in the Vogelkop (topotypical rosenbergit), Wahgi Valley (topotypical 
wahgiensis), southeastern New Guinea, and at Telefolmin shows that 
all series are identical except for the more recently collected specimens 
being slightly more pure black, less blackish-brown below, due _pre- 
sumably to foxing. The race wahgiensis accordingly must be considered 
synonymous with rosenbergii, as concluded by Gilliard and LeCroy 
(JOGU pe 75); 

BREEDING. In the Karimui area gonads were greatly enlarged in 
all the many adult males examined, but not in the females. 

DISCUSSION. ‘The sex ratio on Mt. Karimui is very unbalanced 
(males outnumber females 7:1), as is frequently true in museum col- 


360 


SPECIES ACCOUNTS 


lections of myzomelids. Two factors may contribute, in addition to 
the possibility that the ratio really is unbalanced in nature. (1) Rand 
and Gilliard (1967, p. 533) suggest that “males and females have 
different habitat preferences; the females instead of visiting flowering 
trees more often feed singly among the foliage, and perhaps lower 1n 
the forest.” Most myzomelids are, in fact, collected in flowering trees 
where they congregate in large numbers and are easily secured, so 
that a preference of males for such trees might explain the unbalanced 
ratio in museums. I found that on Mt. Karimui males outnumbered 
females 12:1 in flowering trees but only 5:3 away from flowering trees. 
Corresponding figures on Mt. Albert Edward were 3:2 and 1:1, as on 
Mt. Karimui and in agreement with the suggestion of Rand and Gil- 
liard. (2) Males and females may have different altitudinal preferences. 
Bulmer found that the proportion of adult males was much lower at 
4,000-5,000 ft than at the higher altitudes up to 10,000 ft. At Karimui 
(3,650 ft) both specimens and most birds seen were females (or im- 
matures). 

Myzomela rosenbergii is fairly common from about 4,000 to at least 
10,000 ft in forest and second-growth. Its local abundance appears to 
vary enormously in time and space according to the presence of flower- 
ing trees. On Mt. Karimui’s west ridge during the month we were 
there, there were four such trees: at 4,250 ft, just above Zone 1 and 
beyond collecting and censusing limits; at 4,450 ft in Zone 2; at 6,490 
ft in the upper half of Zone 5; and a fourth in Zone 3 on the side of 
the ridge, where we collected only very briefly. This is reflected in the 
relative abundance figures: Zone 1, 0.0% of the local avifauna; Zone 2, 
In, Zones, [97 Zone 4.27, lower halt ot Zones), 0.09.5 awpper 
halt of Zone, 97,; Zone.6,,0.0%,. Zone 7, 29,; Zones, 129. IM. resem 
bergu reached the bottom of its altitudinal range at Karimui and was 
the rarest of the four myzomelids there. 

M. rosenbergii was netted frequently in high-altitude moss forest on 
Mts. Karimui and Michael, but not at lower altitudes, indicating that 


it stays mainly in the treetops until the forest becomes stunted. 

VOICE. The call is a high-pitched upslurred “tswi” or a high 
“ts-ts”. ‘he song is an energetic, breathless, high-pitched sibilant trill 
or rapid alternation between two notes on different pitches. 


Meliphaga analoga group 


Anyone who has had to work with the nine exceedingly similar 
honeyeaters of the Meliphaga analoga group on mainland New Guinea 
will agree that they pose the most difficult problems of taxonomy, field 
identification, and niche definition in the New Guinea avifauna. All 
can be briefly described as small honeyeaters with olive upper parts, 
gray underparts, and a yellowish or whitish auricular spot. Six of these 
nine species occurred sympatrically and abundantly in the Karimui

SPECIES ACCOUNTS 


area. My general observations on taxonomy, voice, ecology, and field 
identification are summarized here and are followed by the individual 
species accounts. 

Taxonomy.—One’s first impression on starting to work with this 
group is that the forms of New Guinea Meliphaga are a hoax per- 
petrated by previous workers and constitute just a single form showing 
continuous and minor individual and geographical variation. With 
practice, however, it becomes possible to identify many specimens in 
the hand without measurements and to identify most (but not all!) 
of the rest by measurements (cf., Table 15). The grouping of popula- 
tions in different areas into species was long a subject of controversy 
and confusion until clarified in a fine review by Rand (1936), the 
validity of most of whose conclusions has survived subsequent dis- 
coveries of new populations. Rand’s classification appears to me at 
present to require modification in only two or three respects: the 
southern New Guinea populations auwga and setekwa, which Rand 
grouped under M. montana, constitute a distinct species, M. auga 
(p. 368); the population citreola of northern New Guinea belongs to 
M. orientalis, not to M. analoga (Diamond, 1969, pp. 38-46); and 
M. auga may be a synonym of the form known as M. albonotata. ‘The 
characters by which I distinguished the forms of the six species oc- 
curring in my study areas are listed below. It is necessary to realize 
that the minor differences between different species at one place are 
often less marked than the minor differences between different popula- 
tions of the same species, so that this list will not necessarily be 
adequate in other parts of New Guinea. 

I. M. auga auga. Readily identified by the whitish auricular spot 
of the adult, contrasting with the yellow spot of other species. ‘The 
only possible sources of confusion are that the spot is pale lemon to 
yellowish in immatures, and that it is pale lemon to whitish in the 
uncommon M. flavirictus. ‘Vhe underparts are a dull, uniform, rather 
dark olive, very similar to the other species except M. flavirictus. ‘The 
underwing coverts are olive-ochraceous, slightly more yellow and paler 
than in M. mimtkae, averaging more olive than in M. orventalis, and 
distinct from the yellower coverts of the other three species. ‘The inner 
edges of the primaries are pale olive, sometimes olive-ochraceous. ‘The 
size (wing, tail, and weight) is similar to M. mimikae and M. aruensis, 
and larger than the other three species (Table 15). 

2. M. flavirictus flavirictus. The rarest of the six species. Best dis- 
tinguished by the auricular spot, which is pale lemon to nearly white 
(more yellow anteriorly); the marked and bright yellow rictal streak 
(a streak extending from the base of the bill to below the eye), better 
developed than in the other species; the distinctly yellow chin, more 
so than in M. aurensis or M. analoga; the lower mandible, which is not 
black, as in adults of the other species, but horn-colored; and the legs, 
which are less dark than in the other species, orange on the rear sur-

face and dull olive on the front surface. None of these characters is 
infallible taken alone (e.g., immatures of other species may duplicate 
the bill and leg color), but the combination is distinctive. The upper- 
parts are pale, dull, and gray and fairly distinct from the more olive 
and brighter color of the other species. The underwing coverts are 
whitish to yellow, not at all olive or ochraceous. The inner edges of 
the primaries are pale yellow. The underparts are pale, clear, and 
rather lemon as in M. analoga and M. aruensis and unlike the other 
three species. The size (wing, tail, bill, weight) is nearly as small as 
M. orientalis, somewhat smaller than M. analoga, and significantly 
smaller than the other three species. 

3. M. mimikae bastille. The underparts are darker and more un- 
even (more spotted) than in the other species but are approached by 
M. orientalis. The underwing coverts are olive-ochraceous (occasionally 
more olive-yellow), and the inner edges of the primaries are near 
ochraceous (sometimes olive-buff to ochraceous). ‘The auricular spot is 
yellow and of medium size. The bill is stout. The size is large, as in 
M. auga and M. aruensis. No single mark of this species is infallible, 
but the spotted underparts are the best mark, and the combination 
of the above traits is generally diagnostic. The most similar species is 
M. orientalis, from which M. mimikae may be recognized by the 
significantly larger size and stout bill. 

4. M. arvensis aruensis. The auricular spot is yellow, and averages 
larger than in the other species. ‘The feathers of the rump form a 
blackish tuft which stands up somewhat. ‘This offers the best, though 
not an infallible, mark. ‘The underparts are pale and evenly colored 
with a yellowish chin, and resemble M. analoga and M. flavirictus. 
‘The underwing coverts are yellow or yellow-orange, not ochraceous or 
olive. ‘Ihe inner edges of the primaries are yellow, sometimes yellow- 
buff. The size is large, as in M. auga and M. mimikae, and the length 
of the wing and tail averages greatest in M. aruensis. However, the 
stout bill is shorter than in the other five species, including the three 
smaller ones (M. analoga, M. orientalis, M. flavirictus). ‘The face is 
rather blackish between the eye and the auricular spot. ‘The most 
similar species is M. analoga, from which the combination of the rump 
tuft, stout bill, longer wing and tail, and larger auricular spot separate 
i, 

5. M. orientalis facialis. ‘The combination of small size, spotted 
underparts, long and slender bill, and somewhat ochraceous under- 
wing are useful characters. ‘Ihe wing and tail are shorter, and the 
weight less, than in other species except M. flavirictus (those attempt- 
ing to use this key in other areas should be warned that M. gracilis, 
which did not occur in my study areas, is equally small, and that some 
populations of M. orientalis in other parts of New Guinea are not so 
small). The slender bill is as long as in the large M. auga and M. 
mimikae, and more slender than in these or M. aruensis. The under- 


564 


SPECIES ACCOUNTS 


parts are darker and more uneven (more spotted) than in other species 
except M. mimikae, which is slightly darker and more spotted. ‘J he 
auricular spot is smaller than in most other species and bright yellow. 
The underwing coverts are variable, and usually rather orange, gen- 
erally ochraceous olive to ochraceous yellow, occasionally more yellow. 
The inner edges of the primaries are generally ochraceous olive. ‘The 
most similar species are M. mimikae, which has similar underparts but 
is larger and has a stouter bill; M. analoga, which is somewhat larger 
and differs in the underparts and underwing; and M. gracilis, which 
has considerably paler and duller upperparts and paler and even- 
colored underparts. 

6. M. analoga analoga. This species has no single feature that could 
be called distinctive, and must be recognized by a combination of 
characters, each shared individually with other species. ‘The underparts 
are pale, even, and somewhat yellowish on the chin, as M. aruensis 
and M. flavirictus and unlike the other three species. ‘The size is some- 
what smaller than M. auga, M. mimikae, and M. aruensis and some- 
what larger than M. orientalis and M. flavirictus. The underwing 
coverts are yellow, similar to M. arwensis but slightly paler. ‘The inner 
edges of the primaries are yellow, as M. aruensis. ‘The yellow auricular 
spot is slightly smaller than in M. aruensis and larger than in M. 
orientalis. The bill is slender and averages longer than in all the other 
species. The most similar species are M. aruensis, M. orientalis, and 
M. flavirictus, under which the distinguishing marks are listed. 

V oice.—Regretably, meliphagas are as similar and undistinctive in 
voice as in appearance. Meliphagas call frequently. With one exception, 
all the calls I heard were a single, short, and musical note which can 
be rendered as “chip”, “chup”, “tup”, or “tuck” and is either on con- 
stant pitch, slightly upslurred, or slightly downslurred. In the Eastern 
Highlands I identified this call positively from M. auga and M. 
orientalis, with high probability from M. mimikae, and elsewhere in 
New Guinea from M. montana and probably from M. aruensis and 
M. analoga. ‘The one good vocal field mark is that M. auga has in 
addition a distinctive song. 

Ecology.—Of the six meliphagas in the Karimui area, five coexisted 
at Karimui, four at Soliabeda, and three at Bomai. Niche differences 
involve habitat preference, altitudinal range, vertical distribution in 
the vegetational column, and probably feeding habits. (1) M. auga 
was strikingly confined to second-growth and the forest edge and was 
completely absent from the forest interior. (2) Much of the altitudinal 
range of M. orientalis lies above that of all other meliphagas, though 
it meets four other species at the lower extremity of its range (Karimui). 
M. orientalis and M. analoga are ecologically similar and have mutually 
exclusive altitudinal ranges. M. mimikae and M. auga are also hill 
forest species which rarely reach sea level and have a higher ceiling 
than the other species except for M. orientalis. Of the three species 


365 


SPECIES ACCOUNTS 


which reach sea level, M. analoga has a slightly lower ceiling than M. 
aruensis or M. flavirictus, and the ceiling of M. gracilis is so low that 
it failed to reach Soliabeda, my lowest station. (3) Netting returns 
suggest some differences in vertical preferences. M. auga, M. mimikae, 
and M. aruensis were often netted, M. orientalis much less often, and 
M. analoga and M. flavirictus never. (4) The differences in the bills 
suggest differences in feeding habits. The bills of the three lowerstory 
species (M. auga, M. mimikae, and M. aruensis) are stout, those of the 
three middlestory species (M. orientalis, M. analoga, and M. flavirictus) 
slender. Meliphagas in general glean for insects, visit flowering trees, 
and visit fruit trees, but deciding just which species is doing what 1s 
usually difficult. At Karimui Terborgh found meliphagas accounting 
for 7-30% of bird-usage in flowering trees, 66-76% in trees with small 
fruits, and 44% in trees with woody fruits opened by parrots. M. 
flavirictus was shot both in a flowering tree and in a tree with small 
fruits, and M. orientalis was shot in a flowering tree and observed at 
Miarosa in fruiting trees. The white-eared M. auga was also recognized 
in flowering trees. Far more information on stomach contents and on 
what specimens were doing when shot is necessary. 

Iield identification.—M. auga can usually be identified by its white 
ear and by its song, though not by its call. Field identification of the 
yellow-eared meliphagas is at present impossible unless one has care- 
fully compared specimens of the forms known actually to be present 
in the study area, and then only after much practice and under the 
most favorable conditions of light and proximity imaginable. On two 
such occasions I felt confident that I was watching M. mimikae be- 
cause of the uneven underparts. On one occasion I felt that I was 
watching M. aruensis because of the large and bright yellow auricular 
spot and dark face. ‘The small and bright yellow auricular spot of 
M. orientalis might prove of some use as a field mark. Identification of 
yellow-eared meliphagas held in the hand, or prepared as study skins, 
should not be attempted without comparative material.

TAXONOMY. The range and average values of measurements for 
five males (including the type) and four females of nominate auga 
from southeastern New Guinea are: wing, ¢ 82-88 (86.0), @ 75-80 
(77.8); tail, $ 68-75 (72.4), @ 65-67 (66.0); culmen (from base), g 20-22 
(21.3), @ 19-20 (19.3). Birds from the Karimui area thus average a 
trifle larger, and are very slightly duller and darker above, but other- 
wise match auga well. The type and paratype of setekwa differ in the 
slightly more orange axillaries, dirtier breast, and smaller size. Wahgi 
birds were separated by Gyldenstolpe and Gilliard (Gyldenstolpe, 1955, 
p. 166) as gretae, on the basis of having “‘a longer tail and somewhat 
longer wing; general coloration above and on the chest richer green”. 
Specimens of gretae were not available for comparison, but average 
sizes calculated from the measurements cited in the original diagnosis 
(wing ¢ 89.7, 9 81.0; tail g 72.4, 9 68.0 in gretae) are only slightly 
larger than in Karimui or southeastern New Guinea birds, and I doubt 
that gretae differs from auga. Gilliard and LeCroy (1967, p. 78) tenta- 
tively referred 14 white-eared meliphagas from the Adelbert Moun- 
tains to gretae, but examination shows that these specimens are close 
to the distinct and heavily spotted form M. montana huonensis (of 
which Gilliard and LeCroy lacked comparative material) and could 
not belong to the unspotted gretae (= auga?). 

BREEDING. At Karimui testes were moderately or greatly en- 
larged in 1964, slightly or moderately enlarged in 1965. Ovaries were 
generally small except for being enlarged in one 1964 Karimui female. 
One nesting female was collected at Soliabeda. The nest was 15 ft 
above the ground in a bamboo thicket at 1,400 ft near a small river 
and held two young. In shape it was a cup 21% inches bigh and with 


367 


SPECIES ACCOUNTS 


an inside diameter of 2 inches. The outside was constructed of green 
moss; the inside, of dry strands of grass arranged concentrically, with 
a few paper-thin chips of dry bark; and there was a lining of an un- 
identified, fine, soft, white, cotton-like material (possibly the same as 
the material Rand (1942a, p. 362) found in a nest of this species and 
identified as “plant down from the silk cotton tree’). 


DISCUSSION. In my study areas Meliphaga a. auga differed strik- 
ingly in its ecology from other species of Meliphaga in being strictly 
confined to second-growth and the forest edge and completely absent 
from forest interior remote from the edge. It was common in the 
Karimui area from 1,350 to 4,000 ft but absent at Okasa (3,550-4,250 
ft), despite suitable habitat. Gilliard collected one specimen, and 
Gyldenstolpe 14, at Nondugl (5,200 ft). Gyldenstolpe’s (1955, p. 167) 
comments on habitat duplicate my experience: “..... rather common 
in patches of second-growth around Nondugl. Never observed in the 
forests of the Wahgi Divide.” Schodde and Hitchcock (1968, p. 66) 
met M. auga in similar habitat at Lake Kutubu (‘in the lower stages 
of tall secondary and marginal primary forest’). In the feeding trees 
studied by Terborgh he found white-eared meliphagas (M. auga) out- 
numbering yellow-eared individuals (four species) by about two-to-one. 
Solitary individuals of M. auga were also common in shrubbery 3-15 ft 
above the ground, where one was seen eating an insect, and were 
frequently netted. 

In his review of the meliphagas Rand (1936) assembled eight white- 
eared forms, viz., auga, setekwa, montana, sepik, steini, germanorum, 
huonensis, and aicora, to which must be added a subsequently dis- 
covered form margaretae (Greenway, 1966, p. 22), into the single 
species M. montana. Rand noted, however, that the resulting “species” 
showed more geographic variation than any other in the Meliphaga 
analoga complex. More recent evidence suggests that two species are 
involved which are largely allopatric but overlap at Huon Gulf and 
possibly on the Huon Peninsula and in the Vogelkop and Weyland 
Mountains: a second-growth species with a more yellow-olive under- 
wing in southern New Guinea, M. auga (races auga and setekwa, the 
former possibly a synonym of albonotata; see next paragraph); and 
a forest species with a more ochraceous underwing in northern New 
Guinea, M. montana (races montana, margaretae, steini, sepik, ger- 
manorum, huonensis, and aicora). ‘The evidence is as follows. (1) Of 
the two forms of which I have field experience, auga (southern slopes 
of Eastern Highlands) and seprk (North Coastal Range), auga is con- 
fined to the forest edge and second-growth, while sepik lives in the 
forest interior. The taxa auga and sepik have very distinct calls, unlike 
each other’s or that of any other meliphaga. Ecologically, sepik ap- 
pears closer to the yellow-eared species M. mimtkae of southern New 
Guinea. Except for its yellow ear, the large, stout-billed, spotted M. 
mimikae suggests (and is allopatric to) the northern New Guinea

SPECIES ACCOUNTS 


populations grouped under M. montana and is suspiciously similar to 
margaretae, as already noted by its describer, Greenway. However, 
M. mimikae bastille also lacks the distinctive call of sepik, so that I 
do not think that sepik and M. mimikae bastille are actually con- 
specific. (2) The inner edges of the primaries are ochraceous in the 
populations I group under M. montana, predominantly yellow-olive 
in auga and setekwa. (3) A white-eared meliphaga collected at Wau 
(Territory of Papua and New Guinea Museum. No. B 334) belongs 
unmistakably to auga. Wau lies halfway between the type localities 
of the quite different, ochraceous-underwinged races aicora (85 mules 
to the south) and hwonensis (80 miles to the north). ‘Vhus, M. montana 
and M. auga are probably sympatric at Huon Gulf. If auga is a 
synonym of albonotata (see next paragraph), then the two species are 
also sympatric on the Huon Peninsula and in the Vogelkop and Wey- 
land Mountains. Field observations of voice and habitat preference 
of the other populations besides auga and sepik will be necessary to 
test this proposed grouping. 

The remaining white-eared meliphaga is the form known as M. 
albonotata, described in 1876 by Salvadori from D’Albertis’ collection 
on the southern slope of southeastern New Guinea and subsequently 
reported from the Vogelkop and Weyland Mountains by many col- 
lectors, from southwestern New Guinea by Ogilvie-Grant (1915), and 
from the Huon Peninsula by Mayr (1931). I have examined Ogilvie- 
Grant’s specimens, which are in the British Museum of Natural History 
and are close to M. auga setekwa; and I have also examined 13 speci- 
mens from the Vogelkop and Weyland Mountains in the American 
Museum of Natural History, which are also close to M. auga setekwa, 
differing only in the slightly brighter olive back and very slightly 
shorter wing and more slender bill. ‘The type of M. albonotata from 
southeastern New Guinea was not available to Rand when he de- 
scribed auga from southeastern New Guinea, nor was it available to 
me, but Salvadori’s (1881, Vol. 2, p. 333) description of M. albonotata 
fits the type of auga well. All white-eared meliphaga specimens in the 
American Museum of Natural History and in the Territory of Papua 
and New Guinea Museum from the southern slope of southeastern 
New Guinea apparently belong to the same population as the type of 
auga. It may turn out that auga is a synonym of albonotata, and that 
the Vogelkop-Weyland population is conspecific with auga (= ? albo- 
notata) and setekwa and requires naming. 

VOICE. — Since white-eared meliphagas were identifiable by sight 
in the field, the vocalizations of this species could be identified with 
certainty. ‘There are two call notes: a short, cheerful, musical, and 
fairly loud “chip” or “tup” with a sucked-in quality (perhaps more 
sucked-in than the call of M. orientalis?); and a very similar disy]- 
labic note. ‘These calls are not distinguishable from the calls of the 
yellow-eared meliphagas. ‘I'he song is a series of 10-12 thin and quieter

notes at the rate of about 5 per second, dropping in pitch towards the 
end and often rising slightly in pitch at the beginning. No yellow- 
eared meliphaga gave this song.

DISCUSSION. M. mimikae was the commonest forest meliphaga, 
and the commonest yellow-eared meliphaga, in my study areas up to 
4,200-4,500 ft, above which altitude it disappeared. Netting figures 
suggest that it spends much time in the lowerstory, since 48% of the 
specimens were netted. The species is confined to the hills of southern 
New Guinea, mainly between 500 and 4,500 ft, and consists of three 
races known from the following localities. M. m. mimikae, south- 
western New Guinea: Mimika, Kapare, Wataikwa, Iwaka, Setekwa, 
and Utakwa Rivers, from sea level to 2,500 ft but with the great 
majority of the specimens collected in the hills (Ogilvie-Grant, 1915, 
p. 67); upper Setekwa River and southern slopes of the Snow Moun- 
tains, 3,000 ft (collected by A. S. Meek); Alkmaar on the Noord River, 
unspecified but probably low elevation, one specimen reported (Junge, 
1939, p. 60); Fly River, only on the hilly upper reaches at elevations 
above 260 ft (collected by Rand, Second Archbold Expedition). M. m. 
bastille, southern slopes of the Eastern Highlands, 1,350-4,500 fe: 
Karimui and Okapa areas (my collections). M. m. granti, southeastern 
New Guinea, no records below 2,500 ft: Mafulu, 4,100 ft (collected by 
Rand, First Archbold Expedition); Aroa River, 4,000-6,000 ft (collected 
by A. S. Meek); Hydrographer Range, 2,500 ft. 

An adult male yellow-eared meliphaga (A.M.N.H. 342,965) collected 
by Rand at Bernhard Camp (elevation, 160 ft) in the northern New 
Guinea lowlands during the Third Archbold Expedition has been 
used by Salomonsen (1966, p. 4) as the unique type of a new race,

M. mimikae rara. Rand (1942, p. 508) identified this specimen as M. 
analoga flavida and pointed out that it differed in color from the 28 
other specimens he collected of this form but that it was virtually 
identical to M. a. analoga from the upper Fly River. Examination of 
this specimen shows that it is darker-backed than other M. a. flavida 
specimens and superficially not unlike but also not closely similar to 
the known races of M. mimikae. My measurements of it yield: wing, 
83; tail, 69; exposed culmen, 18.5; culmen from base, 22.0. ‘These 
measurements lie towards the upper limit for M. analoga and at the 
extreme lower limit for M. mimikae (only three of 31 males of M. 
mimikae measured have shorter wings). Against the attribution of this 
specimen to M. mimikae are the additional facts that the type locality 
would provide the sole northern New Guinea record; the locality is 
300 miles along the hill slopes from the nearest place of known oc- 
currence of M. mimikae; the elevation would be unusually low, though 
not unprecedented, for M. mimikae; and only a single specimen was 
taken although Rand’s collection was exhaustive and M. mimikae has 
proved abundant at most localities where it occurs. Given these facts, 
the difficulty of identifying even large series of New Guinea meli- 
phagas, and the likelihood that this specimen is merely an individual 
variant of another species, it seems inadvisable to take a single speci- 


men as evidence for a new race and large range extension of M. 
mimtikae. 


VOICE. Since M. mimikae could rarely be distinguished from other 
yellow-eared meliphagas in the field, the call specifically of this species 
was not identified with certainty. However, at localities in the Karimui 
region where M. mimikae and other yellow-eared meliphagas were 
present, all vocalizations of yellow-eared meliphagas consisted of a 
single very similar call note, described on p. 365. Since 60-95% of the 
yellow-eared meliphagas were M. mimikae, I assume that it was re- 
sponsible for most of these vocalizations.

are not identical, but the differences are not sufficiently marked or 
well-established to justify naming of new races. The principal differ- 
ences are that birds from the Vogelkop (3 ¢, including the type: wing, 
71, 75, 77; tail, 56, 59; 61: culmen from base, 21.5, 22.0) and the 
Weyland Mountains (2 6, wing, 78, 79; tail 63; 06; culmenurom: base, 
22, 22) have longer wings and tails than those from the southern slope 
of the Snow Mountains (wimer so 745 2 =o OoRandy legen alae cs 
2 2 56 and 57; culmen from base, 1 ¢ 22.0,2 2 20.0 and 20.0) or my 
series. In addition, my birds show some approach to nominate 
orientalis of southeastern New Guinea in that the underparts are less 
spotted, and the upperparts darker, grayer, and less bright, than in 
other facialis populations, but they are still nearer facialis than 
orientalis in these respects. The nearly black postocular stripe of 
orientalis is greatly reduced in facialis, including my specimens. ‘The 
race becki is considerably larger and still less spotted below, while 
citreola (formerly considered a race of M. analoga; Diamond, 1969) 
is yellower. 


BREEDING. Gonads were small in all specimens. 


DISCUSSION. In my study areas the altitudinal range of M. 
orientalis lay for the most part above those of its congeners. In the 
Okapa area it was the only meliphaga at Awande (up to 6,200 ft) and 
Miarosa (5,800 ft), and shared Okasa (3,550-4,250 ft) only with M. 
mimikae. In the Karimui area it descended to Karimui (3,650 ft), 
where four other species were present, but not to Bomai (3,250 ft); it 
shared Zone | of Mt. Karimui (4,000-4,200 ft) only with M. mimikae; 
and it was the only meliphaga on Mt. Karimui above 4,400 ft until it 
dropped out around 5,600 ft. Its maximum abundance (5-79% of the 
local avifauna) was at 4,400-5,600 ft. The fairly abrupt disappearance 
above this limit may have been correlated with the increase in abun- 
dance of Ptiloprora guiset, while the decline in abundance at lower 
altitudes may have been correlated with the appearance of the other 
meliphagas, particularly the similar M. analoga. 

Two of the specimens on Mt. Karimui were shot in the flowering 
tree at 4,450 ft. The habitat appears mainly to be the forest interior, 
though one was collected and another seen in a tree in a garden at 
Miarosa. Only four specimens were taken in nets. Of these four netted 
birds, three were obtained on a single day at Awande near the forest 
edge, the fourth at Karimui, and none was netted in the undisturbed 
forest of Mt. Karimui. Six specimens were in trees or the tops of trees 
when shot. Probably M. orientalis is more of a middlestory and upper- 
story than lowerstory species in the forest interior, and utilizes the 
lowerstory mainly at the forest edge. Its altitudinal range excludes 
that of the similar M. analoga, the slender-billed middlestory forest 
meliphaga of lower elevations (cf., also, Diamond, 1969). 


VOICE. Since this was the only member of the genus in Zones 2,

3, and 4 of Mt. Karimui, calls of meliphagas in these zones are as- 
sumed to be of this species. ‘here are three similar call notes: a 
bright, short, monosyllabic “tuck”; a bright, short, slightly disyllabic 
(or else slightly upslurred) note, with the second syllable slightly higher; 
and a similar disyllabic call except with a thinner quality and with the 
second note lower. These calls were indistinguishable from calls of 
yellow-eared meliphagas at Karimui, Bomai, and Soliabeda, assumed 
to come mostly from M. mimikae.

TAXONOMY. In his review of the meliphagas Rand (1936, p. 14) 
pointed out, “All of the populations included in this race [analoga|] 
are not identical but the differences between various groups of in- 
dividuals are not sufficient to be used in separating races.” “Iwo new 
races, connectens (from Beck’s Madang series) and papuae (from 
Rand’s Wuroi series) have been described by Salomonsen (1966, p. 5) 
from the material already discussed by Rand. Gilliard and LeCroy 
(1968, p. 36) reaffirmed that connectens is not separable from flavida. 
The type of flavida (type locality Japen) is the yellowest of the 15 
Japen specimens I examined, and the average color differences among 
flavida populations from Japen, Madang, Wewak, Hollandia, and the 
Idenburg River are irregular and trivial. Several of the characters used 
to separate papuae (type and paratypes examined) from analoga had 
already been pointed out by Rand and are equally irregular and 
trivial. 

BREEDING. Gonads were small in all specimens. 


DISCUSSION. None of the specimens was netted. ‘This meliphaga 
appears to replace M. orientalis as the slender-billed meliphaga of the 
forest middlestory at lower elevations. In the Karimui area the transi- 
tion lay somewhere between 3,250 ft (highest record of M. analoga) 
and 3,650 ft (lowest record of M. orientalis).

TAXONOMY. The main difference between the three available 
specimens of crockettorwm (Idenburg River, Sepik River, and southern 
slope of Snow Mountains) and six specimens of nominate flavirictus 
(southeastern New Guinea and Fly River) is the yellow auricular spot 
of the former as opposed to the paler, lemon-whitish spot of the 
latter. On the basis of this character my specimens are unequivocally 
flavirictus, as expected on geographical grounds. 

DISCUSSION. None of these specimens was netted. The Mengino 
specimens were among many meliphagas and other honeyeaters feed- 
ing in a tree with small berries at 4,600 ft.

TAXONOMY. Comparison with specimens of all nine races from 
the New Guinea mainland yielded the unexpected result that birds 
from both the Karimui area and Okasa are closest to rubirensis, the 
Weyland Mountains race, from which they differ only in having 
slightly darker upperparts. One might have expected them to be 
giulianettiz, the southern watershed race both to the east and to the 
west, to which Mayr and Gilliard (1954, p. 369) assigned their two 
specimens (from an unstated locality) without comment and to which 
Schodde and Hitchcock also assigned Lake Kutubu birds. However, 
specimens of giulianetti from Mafulu, Baroka, and Kubuna in south- 
eastern New Guinea and from Palmer Junction on the upper Fly 
River are paler above, much paler below, and duller brown on the 
breast than the Karimui and Okasa series. Specimens of saturatior 
from the lower Fly River and Aru Islands are also paler and duller 
below and have the edges of the wing coverts less bright rufous. Birds 
from the Setekwa River on the southern slope of the Snow Mountains,

Vol. 12, but do not belong to the Meliphaga analoga complex.

assigned to saturatior, are slightly darker below than Fly River and 
Aru Islands specimens and show a tendency towards rubiensis 1 this 
respect. The races chrysotis, madaraszi, spilogaster, kumusit, philemon, 
and vis? all show marked differences. 

BREEDING. Gonads were small in most specimens except 1n 
1964 at Karimui, where most testes were enlarged. 

DISCUSSION. Meliphaga flaviventer is one of the most abundant 
bird species in the lowlands, becoming less common with increasing 
altitude until it disappears completely around 5,000 ft. Its contribution 
to the avifauna in the Karimui area was 7% of the local avifauna at 
Soliabeda, 5% at Karimui, and 1.8% on Mt. Karimui, where the 
highest record was at 4,850 ft. 

Both flowering and fruiting trees were utilized. Meliphaga flavi- 
venter accounted for 5-25% of the bird-usage in flowering trees at 
Karimui, 10-40°% in trees with fruits smaller than 5 mm at Karimui, 
Okasa, and Mengino, and 23% in the tree at Karimui with hard- 
shelled fruit opened by parrots. It was absent in trees with soft fruits 
larger than 10 mm. In these feeding trees it could be seen in both the 
upper and lower half of the tree but was twice as numerous in the 
lower half. Outside of fruit trees it was commonest from 5 to 50 ft 
above the ground, so that relatively few specimens were netted. Chases 
of one individual by another took place occasionally, and one pair 
was observed attempting copulation in flight. 


VOICE. ‘The song is a phrase of usually three notes, repeated five 
to 10 times in succession and reminiscent of the songs of caprimulgids. 
In the commonest version all notes are somewhat upslurred, particu- 
larly the first; the first note is highest and the third lowest in pitch; 
and the interval between the first and second note is twice as long as 
that between the second and third note or between repetitions of the 
pattern (Fig. 39). ‘The pitch is in the lower middle registers, the 
quality clear, and the volume loud. When one individual starts sing- 
ing, others nearby may begin after a few repetitions of the pattern and 
continue more or less in synchrony. The song is suggestive of that of 
the honeyeater Philemon novaeguineae in the use of a repeated pat- 
tern, in the pattern itself, and in quality. Songs I heard near Port 
Morebsy and Lae were very similar to those in the Eastern Highlands, 
but songs in the North Coastal Range differed by being delivered 
nearly twice as fast, suggesting that a comparison of songs and morpho- 
logical subspecific characters at different localities might prove interest- 
ing.

TAXONOMY. ‘These specimens agree with lophotis of the Huon 
Peninsula and southeastern New Guinea, which has a large yellow 
ear patch. ‘The patch is smaller in potkilosternos and nearly lacking in 
septentrionalis, while candidior has smaller black spots on the under- 
parts. 


BREEDING. The latest male collected at Karimui (4 Aug.) and 
one of the two males on Mt. Karimui (15 Aug.) had slightly enlarged 
testes, while gonads were small in the other specimens. 


DISCUSSION. ‘This hill forest species was present up to 4,500- 
4,600 ft but did not occur as low as Soliabeda (2,000 ft). It was also 
recorded from Lake Kutubu (2,450 ft). 

In the Karimui area Meliphaga polygramma occurred regularly but 
usually singly in feeding trees. It was observed in all seven flowering 
trees studied at Karimui and in the one at 4,400 ft on Mt. Karimui, 
where it made up 5-1%% of the bird-usage. It accounted for 1-2% of 
the bird-usage in trees with small fruits at Karimui and Mengino, and 
16% in the Karimui truit tree with hard-shelled fruits opened by 
parrots. Its vertical distribution through the feeding trees appeared 
nearly uniform, but it was rarely seen in the understory or netted. In 
behavior it is silent and unobtrusive, and easily overlooked if one does 
not seek it in feeding trees. 


VOICE. Neither Stein (1936, p. 32) nor I ever heard a sound from 
this honeyeater.

STOMACH CONTENTS. Usually insects, but 3% of stomachs examined con-

TAXONOMY. These are nearer to the dark southeastern New 
Guinea race salvadorti than to melanolaema. 

BREEDING. ‘Testes were slightly enlarged in two males, con- 
siderably enlarged in the other two. One female had an enlarged 
ovary. Birds in song were heard from the top to the bottom of the 
altitudinal range. 

DISCUSSION. At higher altitudes Meliphaga subfrenata is the 
medium-sized honeyeater in flowering trees, which it shares with the 
small Myzomela rosenbergii and the large Melidectes rufocrissalis (or 
M. belfordi). It occurs up to timberline, where it sometimes perches 
in tree ferns in alpine grassland near the forest edge. Its lower limit 
is usually about 7,000 ft, but it ranged down to 4,400 ft on Mt. 
Karimui, where it was fairly common (1.5% of the local avifauna). 
Its vertical distribution is mainly from 10 ft above the ground 
to the crowns, infrequently in the understory, once seen on the ground. 
Away from flowering trees I have seen it flycatching, and also clumsily 
hopping up a large vertical trunk like a would-be woodpecker, probing 
the bark, sipping a couple of times, then flying to the base of another 
trunk and ascending it in the same fashion. Males and females are 
equally common in flowering trees and away from them and do not 
differ in altitudinal distribution nor in vertical distribution through 
the vegetational column. 

VOICE. As described elsewhere (Diamond and Terborgh, 1968, 
p. 74), the song is “a rapid, loud, bubbling, and cheerful series of notes 
which first rises and then falls in pitch, progressively decelerating and 
sometimes concluding in three slurs on the same pitch, after which the 
pattern is immediately repeated one or two times.” The quality and 
pattern of the song as well as the frequency of countersinging are 
quite similar to the song of Meliphaga versicolor.

BREEDING. Gonads were small in all specimens. 


DISCUSSION. The unsexed Mt. Karimui specimen is probably 
male, from its wing length. The local sex ratios are very unbalanced 
(only females at Karimui, mainly males at Soliabeda). 

I found this uncommon honeyeater of the hill forest only at the 
three above-cited localities where specimens were collected (2,000-4,630 
ft). It was regularly seen in low numbers in trees with small fruits and 
in flowering trees, which it shared with up to 11 other species of 
meliphagids and where it accounted for 2-5% of the bird-usage. Meli- 
phaga obscura was silent, slower in its actions than members of the 
Meliphaga analoga complex, and fed strictly in the lower branches and 
middlestory, never ascending into the upper half of the vegetational 
column. In addition, I have a few sightings of single individuals 5-10 
{t above the ground in second-growth and gardens. Males frequented 
flowering trees and were never netted, while females were netted in 
the understory away from flowering trees.

TAXONOMY. ‘The races cinereus and dorsalis are less heavily 
spotted below. ‘There may be an increase in size with altitude, since 
the two birds with the longest wings (111 and 112) were from the 
highest altitudes (Awande, 6,200 ft, and Mengino, 5,800 ft) and since 
the Mt. Karimui female (4,750 ft, wing 105) was larger than the three 
Karimui females (3,650 ft, wing 96, 101, 102). 

BREEDING. The testes of one Karimui male were slightly en- 
larged, but gonads in all other specimens were small. 

DISCUSSION. Pycnopygius cinereus occurs in the forest interior 
but most often at the forest edge and in second-growth between about 
3,500 and 6,500 ft, and is commonest in the lower part of its altitudinal 
range. The only record in the undisturbed forest of Mt. Karimui was 
the single specimen at 4,750 ft. In behavior it was a silent, solitary, 
sluggish, and inconspicuous bird of the upperstory, frequenting trees 
with flowers or small fruits. Only one specimen was netted. At a 
Miarosa fruit tree it was repeatedly driven off by another honeyeater,

Melidectes torquatus, which is nearly the same size. Besides similar 
sizes, Pycnopygius cinereus and Melidectes torquatus have somewhat 
similar habits (upperstory, commonest in ecologically disturbed areas, 
attracted to fruit trees), but generally Melidectes torquatus is far more 
abundant. At the two localities where I found Pycnopygius cinereus 
common, Melidectes torquatus was either uncommon (Okasa) or absent 
(Mengino), suggesting that the more aggressive Melidectes torquatus 
may limit its distribution. 

VOICE. As with its congener P. ixoides, I never heard any vocali- 
zation from P. cinereus, nor did Stein (1936, p. 32).

brigher and richer. ‘The underwing coverts are bright ochraceous, 
and the feathers of the crown are edged gray. The race finschi from 
the north coast of southeastern New Guinea is so much brighter rufous 
below that at first glance one might not have placed it in the same 
species. here appears to be only one record from the south coast of 
southeastern New Guinea (N.G.B.S. Newsletter, No. 35, p. 2, Sept. 
1968). I have no Vogelkop material (topotypical ixoides) by which to 
assess the proposed southern New Guinea race cinereifrons (Salomonsen, 
1966). 


BREEDING. Gonads were slightly enlarged in one Karimui male, 
small in other specimens. 


DISCUSSION. Pycnopygius ixoides is the low-altitude representa- 
tive of the somewhat larger P. cinereus, to which it is very similar in 
behavior. ‘The altitudinal ranges of the two species overlap around 
3,500-4,500 ft. P. ixoides was fairly common in the Karimui area up to 
3,900 ft, while P. cinereus extended down to 3,650 ft. The only other 
Eastern Highlands record to date is the Mengino specimen, taken at 
4,600 ft within the vertical range of P. cinereus. Like P. cinereus, P. 
ixoides is solitary, slow-moving, inconspicuous, and silent, and fre- 
quents the middle- and upperstories. It was never netted. At Karimui 
there were a few observations in flowering trees and in trees with small 
fruits.

‘TAXONOMY. ‘The color is darker, and the knob on the culmen 
smaller, than in most but not all Fly River specimens. 

While the race jobiensis from the north coast is fairly distinct, dif- 
ferences among the populations of the Vogelkop and south coast are 
minor and complicated by individual variation and effects of wear 
on color. Birds in this area have been variously distributed among 
three races, nominate novaeguineae, brevipennis, and aruensis, on the 
basis of differences in wing length, bill, and depth of color, without 
any agreement being reached among authors (Rothschild and Hartert 
(1913, p. 513), Ogilvie-Grant (1915, p. 78), Mayr and Rand (1937, p. 
Zoe), Wand (19424, p. 064), and Junge (1959) p. (eb; 1953p, 73) ne 
cently Salomonsen (1966, p. 9) described the southeastern population, 
which Mayr (1941b, p. 211) had refrained from naming, as fretensis, on 
the basis of material already reviewed by Mayr and Rand and using 
the same characters (fretensis described as slightly paler and much 
larger) extensively discussed previously. I have therefore reviewed the 
material in the American Museum of Natural History from the west- 
ern Papuan Islands, Vogelkop, Setekwa River, Fly River and south- 
eastern New Guinea. 

Within this area differences in slenderness of the bill and the size of 
the knob on the culmen seem as inconsistent and slight to me as they 
did to Ogilvie-Grant, Mayr and Rand, and Junge. As noted previously, 
average differences in color are of little help as subspecific characters 
in this species due to nongenetic variation: “Wear and fading produce 
such great changes in the color of the plumage of this species that it is

difficult to compare any but specimens which are actually molting”’ 
(Mayr and Rand, 1937, p. 234). Rand (1942a, p. 364) found that birds 
from more arid areas were paler, due apparently to more pronounced 
wear. Table 16 assembles measurements of wing length in 43 males 
available to me (including the types of brevipennis and fretensis) and 
from measurements of other authors. It appears from these figures 
that birds from the Vogelkop and western Papuan islands average the 
largest, with Junge’s specimens standing out as especially large; those 
from Etna Bay, 35 miles from the type locality of novaeguineae (Lobo 
on ‘Triton Bay), average about 4 mm smaller; those from southeastern 
New Guinea (including the type of fretensis) average 1 mm shorter; 
Fly River birds average 1-4 mm shorter; and those from southwestern 
New Guinea exclusive of Etna Bay average another several millimeters 
shorter. Thus, wing length decreases clinally eastward from the Vogel- 
kop to Etna Bay to the southwestern New Guinea coastal plain and 
then increases clinally further eastward to the Fly River and to south-

eastern New Guinea. In separating fretensis from brevipennis Salo- 
monsen cited the longer wing of the former, but the specimen selected 
as the type of fretensis is the largest specimen from southeastern New 
Guinea, while the type of brevipennis is the second smallest specimen 
from southwestern New Guinea. The smallest population (southwest- 
ern New Guinea) overlaps somewhat with the largest population 
(Vogelkop) and extensively with the intermediate populations. 

‘There seem to be only two reasonable alternatives: to consider south- 
western New Guinea riverplain birds as brevipennis and the rest as 
nominate novaeguineae, or else to consider all the Vogelkop and south 
coast populations as novaeguineae. Because the former procedure gives 
novaeguineae a discontinuous range and the sizes overlap, the latter 
procedure may be preferable. In either case fretensis must be consid- 
ered a synonym of novaeguineae. 


DISCUSSION. I met Philemon novaeguineae, one of the noisiest, 
most conspicuous, and characteristic species of the New Guinea low- 
lands, only at Soliabeda, where several individuals frequented the 
crowns Of isolated trees. It was surprising not to find it in the Karimui 
Basin, which so many other lowlands species had reached. On the 
northern watershed the race jobiensis seems to have been much more 
successful at colonizing midmontane cultivated areas: Bulmer found 
it to be present in the upper Wahgi Valley and common in the Batyer, 
Jimmi, and Kaironk valleys up to about 6,000 ft. Possibly this coloniza- 
tion is actively underway, since Ripley (1964, p. 72) found P. n. 
jobiensis in the Baliem Valley of western New Guinea in 1960, where 
the Third Archbold Expedition had not found it in 1938 and 1939 
despite exhaustive collections. Schodde and Hitchcock (1968, p. 67) 
report that the population of Philemon novaeguineae at Lake Kutubu 
is migratory, disappearing during the wet season there (May to 
September). 

The problem of the parallel geographical variation in the forms of 
Philemon and of the oriole genus Orzolus through the Molucca-Timor- 
New Guinea area has attracted attention ever since Alfred Russel 
Wallace described this variation a century ago in his classic The 
Malay Archipelago (1962) as a case of mimicry. Briefly, the Philemon 
populations inhabiting seven islands in this area (Ceram, Buru, ‘Ven- 
imber, Halmahera, Wetar, Timor, and New Guinea) show great inter- 
island variation, and the Oriolus populations show equally great vari- 
ation, but on each island the Oriolus form and the Philemon form 
resemble each other, often to such a stunning degree that specimens in 
the hand can be distinguished only with difficulty. In the field I have 
frequently confused the New Guinea forms, Philemon novaeguineae 
and Oriolus szalayi, even though the morphological resemblance is 
less close than on the other six islands (both forms largely brown, the 
bare black facial skin in Philemon paralleled by heavy black streaking 
on the face and sides of the throat in Orrolus, Oriolus more distinctly

streaked below). The morphological similarity on New Guinea is 
reinforced by similarity in habits, viz., in that both forms inhabit the 
middle- and upperstory of second-growth and rarely the forest interior, 
have approximately the same altitudinal range, and are social. On 
the island of Ceram Oriolus forsteni and Philemon subcorniculatus 
are virtually indistinguishable (large birds, mostly unstreaked brown, 
with a yellow-olive wash on the breast, gray collar on the nape, dark 
ear coverts). Oriolus b. bouroensis and Philemon m. moluccensis on 
Buru, and Oriolus b. dicipiens and Philemon m. timorlaoensis on 
Tenimber are largely brown without a yellow breast wash, with a re- 
duced pale nape collar, and with a bare black facial patch of Philemon 
duplicated by a similar area of black feathering in Oriolus. On Halma- 
hera Philemon fuscicapillus and Oriolus phaeochromus are entirely 
dark brown, the bare black facial patch of Philemon much reduced 
and the black facial feathering of Oriolus absent. Philemon buceroides 
pallidiceps and Oriolus viridifuscus finschi of Wetar, and Philemon Db. 
buceroides and female (but not male) Oriolus v. viridifuscus of ‘Timor, 
are pale below, unlike the previously mentioned forms, and a bare 
black facial patch contiguous with a bare black patch on the side of 
the neck in Philemon is duplicated by similar areas of black feathering 
in Oriolus. Further details of plumage are given by Wallace (1962, 
pp. 305-307) and by Stresemann (1914b, pp. 395-400). 

Wallace (1962) attributed this remarkable parallel variation to 
Batesian mimicry of Philemon by Oriolus, arguing that hawks avoid 
the noisy, pugnacious Philemon with its strong claws and beak. Strese- 
mann (1914b) rejected this interpretation on the grounds that selection 
by hawk predation was probably insignificant, and argued instead that 
the convergence was a coincidence due to common selective forces act- 
ing on both forms and that the appearance of either Oriolus or 
Philemon on an island would have been the same even if the other 
form had been absent. However, the resemblances in pattern are so 
detailed and striking that Stresemann’s interpretation appears to me 
thoroughly implausible. A more promising approach to the problem 
stems from recent discussions by Moynihan (1968) and by Cody (1969), 
who have pointed out numerous similar cases of convergence in plum- 
age between two unrelated bird species, usually ones which utilize 
similar food resources. Cody suggests that the convergence facilitates 
interspecific territoriality, while Moynihan refers to the convergence 
as “social mimicry’, e.g., to facilitate interspecific flocking. The selec- 
tive forces for convergence in the Philemon-Oriolus case remain un- 
known. 

VOICE. ‘The songs are the most characteristic bird sounds of the 
New Guinea lowlands. ‘They consist of a somewhat nasal pattern of 
three or four slurred notes, repeated several times with pauses of 
less than a second between repetitions and with successive repetitions 
somewhat louder (Fig. 40).

TAXONOMY. Im color this specimen is intermediate between 
the western race occidentalis and the eastern race meekiana. It is nearer 
occidentalis in the brighter and greener upperparts and in the brighter 
yellow underparts and equidistant from the two races in the throat 
(slightly darker gray in occidentalis). Wing measurements for nine 
occidentalis females from the north slope of the Snow Mountains are 
78-84 (79.9), and for two females of meekiana from the Huon Penin- 
sula and southeastern New Guinea, 73 and 75. Since my specimen is 
nearer occidentalis in color but matches meekiana in size, racial assign- 
ment will have to await further material. 


DISCUSSION. ‘The specimen, which represents the sole record for 
the Eastern Highlands, was netted at 8,000 ft on Mt. Michael, where 
P. guisei was common. Except on the northern slopes of the Snow 
Mountains, this is a rare and local species throughout its wide range. 
The two races have very different altitudinal ranges: meekiana of 
southeastern New Guinea lives at 4,600-7,500 ft (mainly 5,000-7,000 
ft), while occidentalis of western New Guinea lives at 7,200-9,200 ft.

DISCUSSION. Relations in the Ptiloprora guisei-perstriata com- 
plex, formerly considered a single species, were clarified by Mayr and 
Gilliard (1954, p. 369; Gilliard and LeCroy, 161, p. 80). P. guiser 1s 
present at medium altitudes in eastern New Guinea and reaches its 
western limit somewhere between Mt. Giluwe and ‘Telefolmin. P. 
perstriata occurs at medium and high altitudes in western New 
Guinea but lives in eastern New Guinea only at high altitudes above 
P. guisei. I take this situation to mean that P. perstriata originated in 
western New Guinea as a form allopatric to P. guiset and reinvaded 
the latter’s range relatively recently. P. mayri, a member of the same 
complex, lives on two of the north mountain “islands” (Cyclops Moun- 
tains and North Coastal Range). The very similar P. erythropleura 
may constitute the Vogelkop representative (Diamond, 1969). . 

On Mt. Michael the transition between P. guisei and P. perstriata 
took place around 9,500-10,500 ft. Our records suggest that the two 
species might overlap by several hundred feet, but this is uncertain. 
Gilliard found that the transition on Mts. Hagen, Kubor, and Wilhelm 
was around 8,000 ft. 

P. guisei is the most abundant and characteristic bird of moss forest, 
and is tied sufficiently strongly to this vegetational structure or the 
associated climatic conditions that the lower limit of its altitudinal 
range shows marked and predictable local variation. On Mt. Michael, 
where heavy mossing began at 8,700 ft, P. guiset was common from 
8,000 ft upwards but not at lower altitudes. On our walk from Mt. 
Michael to Karimui we passed through a very local tongue of moss 
forest which descended to 6,000 ft between Agotu and Maiba, and 
immediately encountered P. guisei, after not having found it at the 
same and higher elevations during a week at Mengino. In the Okapa 
area, where we failed to encounter mossy conditions in our study zone 
(5,800-7,000 ft), the two specimens at Awande (6,000 ft) constituted 
the sole record. On Mt. Karimui, where the moss level was at 6,500 ft, 
P. guise: became common a few hundred feet below that altitude, 
remained common up to the summit at 8,165 ft, and trickled down to 
4,400 ft in low numbers. 

Census figures for P. guise? on Mt. Karimui clearly illustrate its 
association with mossy conditions: Zone 2 (4,400-4,750 i); 13697, OF ihe 
local avifauna; Zone 3 (4,750-5,390 ft), 0.59%; Zone 4 (5,390-5,960 ft), 


as 
2.3%; lower half of Zone 5 (5,960-6,250 ft), 1.4%; upper half of Zone 
5 (6,250°0,500 it), 92%; Zone 6 (6,500-7,080 it), 14.4%; Zone 7 (7,080- 
2,020 10), 24.47,; Lome $-(7,610-6,166: it), 27%. 

The abundance of P. guisei on Mt. Karimui made it possible to 
determine its population structure in detail. Zone 2 yielded three 
females and a male with tiny testes; Zone 3, one female; Zone 4, five 
females, one of them (netted at the border of Zones 4 and 5) with 
somewhat enlarged ovaries; and the lower half of Zone 5, a short- 


winged young male with tiny testes. In the upper half of Zone 5, 


385 


SPECIES ACCOUNTS 


near the moss level, songs were heard commonly, none at all having 
been heard at lower altitudes; and the sex ratio suddenly approached 
equality, with the testes of all males but one enlarged. Songs remained 
common, and the sex ratio remained near equality, in Zones 6 through 
8. All males in Zone 6 had enlarged testes. In Zones 7 and 8, testes 
were much enlarged in half of the males, small or tiny in the others. 
Thus, nonbreeding birds show some accumulation at the top of the 
range in addition to descending 1,500 ft below breeding birds. 

P. guisei seems to take over the niche filled by the genus Meliphaga 
at lower altitudes, as the common meliphagid gleaning for insects in 
the lower and middle stories. It is occasionally seen in flowering trees 
but does not concentrate in them. In behavior it is solitary and moves 
rapidly (1-3 ft every second or every few seconds), often hanging up- 
side-down to probe. 


VOICE. A variety of simple and quiet two- or three-note calls, the 
individual notes of which usually contrast in quality with each other. 
‘The characteristic elements include: a plaintive whistled slur, which 
may be upslurred, downslurred, or more complex; a staccato “chip”; 
and a short buzzy note. ‘The commonest combination is for a short 
staccato or buzzy note to be followed by a slur, or vice versa. A call is 
given every 2-3 sec for 1 min or more (Fig. 41). The voices of P. mayrt 
and probably of P. perstriata and P. erythropleura are quite similar.

close to nominate perstriata of southeastern New Guinea that the race 
lorentzi cannot be recognized. ‘The race perstriata must be considered 
as encompassing the entire continuous 900-mile range of the species 
on the Central Range, with the second race praedicta isolated on the 
Wandammen Peninsula. 


BREEDING. One of the males had enlarged testes. 


DISCUSSION. Most of the specimens were netted. 

P. perstriata lives at altitudes just above its sibling P. guisei on the 
higher peaks of the Eastern Highlands. On Mt. Michael I found it 
down to 9,500-10,000 ft in forest and all the way up to the summit at 
12,300 ft, where it was common in the tongues of stunted trees and 
bushes reaching onto the summit cap of alpine grassland. Gilliard 
reported it above 8,000 ft (but apparently most commonly at 10,000 
to 11,000 ft, judging from the altitudes given on his specimen labels) 
on Mts. Wilhelm, Hagen, and Kubor. On Mt. Karimui (8,165 ft) it 
was absent. 


VOICE. Calls of P. perstriata that I heard on the summit of Mt. 
Michael were very similar to the calls of P. guisei. Halcyon torotoro 
and H. megarhyncha provide an additional example of congeners 
which replace each other altitudinally and are very similar vocally as 
well as morphologically. 


Niche Differences in the Genus Melidectes 


A review of interrelationships among the 10 species (all but M. 
whitemanensis confined to New Guinea) of the genus Melidectes is 
necessary as background for discussion of two questions under the 
species accounts: Why is the range of Melidectes princeps restricted 
to the Eastern Highlands? How did the unusual patterns of distribu- 
tion and hybridization in the M. belfordi-M. rufocrissalis group arise? 

On the basis of song, plumage, and bill form the species fall into 
two groups. ‘The six members of the first group (M. torquatus, M. 
ochromelas, M. rufocrissalis, M. leucostephes, M. foersteri, and M. 
belfordi) have throat and/or gape wattles, a large bare patch of facial 
skin, pale edges on the back, are large (40-105 g), have relatively stout 
bills, and have similar loud nasal songs which frequently involve 
duets. ‘he first four of these forms are confined to middle elevations 
(ca. 3,000-8,000 ft); M. foerstert occurs both at middle elevations and 
in the alpine zone; and M. belfordi occurs at middle elevations 
throughout its range, and also in the alpine zone in some parts of its 
range but not in others. M. rufocrissalis, M. leucostephes, and M. 
foersteri constitute a superspecies. ‘The four members of the second 
group (M. fuscus, M. nouhuysi, M. princeps, and M. whitemanensis) 
lack throat or gape wattles, have a very small bare patch of facial skin, 
lack pale edges on the back, are medium-sized (25-60 g), have relatively 
slender bills, and have similar soft songs which do not involve duet- 


387 


SPECIES ACCOUNTS 


ting. M. fuscus and the M. nouhuysi-M. princeps superspecies are re- 
stricted to the New Guinea alpine zone. M. whitemanensis is confined 
to the island of New Britain, and was originally described as a mono- 
typic genus Vosea, but its song, behavior, and morphology suggest that 
it is a Melidectes nearest M. fuscus (Diamond, 1971). 

Only at alpine elevations does one find more than one species num. 
erous in a given habitat. The details of distribution are such that each 
alpine area on the Central Range supports two species, no more and no 
less (“compound checkerboard allopatry’’). Southeastern New Guinea 
has M. fuscus and an alpine race of M. belfordi: the Eastern Highlands 
have M. fuscus and M. princeps but no alpine M. belfordi; the north- 
ern slope of the Snow Mountains has M. nouhuysi and another alpine 
population of M. belfordi (M. fuscus is known on the northern slope 
only from a single specimen); and the southern slope of the Snow 
Mountains has M. nouhuysi and M. fuscus, but not M. belfordi, 
which apparently remains below 8,000 ft, from published reports of 
Ogilvie-Grant (1915, p. 61) and Junge (1939, p. 57). The isolated moun- 
tains of the Huon Peninsula, on which the area at alpine elevations is 
very small, have only M. foersteri at these elevations. Niche differences 
in the alpine zone are probably behavioral. M. belfordi frequents 
flowering trees and remains in the crowns; M. fuscus is half as large 
and gleans throughout the vegetational column, not in flowering trees; 
M. nouhuyst remains in alpine shrubbery at and above timberline, 
often on the ground; and the behavior of M. princeps has not been 
reported. 

Niche differences between the species of the first group at middle 
elevations involve spatial segregation, in the sense that all the species 
occupy the same kind of niche in different habitats or geographical 
areas or at different altitudes. M. torquatus occurs on all the main 
mountain ranges of New Guinea in open second-growth, whereas the 
remaining midmontane species are mainly forest birds. ‘The geographi- 
cal ranges of M. ochromelas, the M. rufocrissalis superspecies, and M. 
belfordi are all peculiar when considered individually, in that each 
extends widely over New Guinea but is missing from large areas of 
the total range. When considered together, however, these ranges are 
found to provide a peculiar case of checkerboard allopatry, in that 
most areas have two species, never more and usually no less, and the 
altitudinal ranges of the two species in a given area are mutually ex- 
clusive. The details are as follows: southeastern New Guinea, M. bel- 
fordi at higher elevations, M. ochromelas at lower elevations (my 
observations on Mt. Albert-Edward); Huon Peninsula, M. foersteri 
(rufocrissalis superspecies) at higher elevations, M. ochromelas at lower 
elevations (Mayr, 1931; Mayr, 1941b, p. 198; labels of specimens col- 
lected by Beck); Schrader Range and Star Mountains, M. belfordi at 
higher elevations, M. rufocrissalis at lower elevations in ecologically 
undisturbed areas (Bulmer, personal communication; Diamond, 1967, 


388 


SPECIES ACCOUNTS 


p. 12; Gilliard and LeCroy, 1968, pp. 33-35; Mees, 1964, p. 27); Wey- 
land Mountains and southern slope of the Snow Mountains, M. bel- 
fordi at higher elevations, M. ochromelas at lower elevations (Ogilvie- 
Grant, 1915, p. Gly Stem, 1926, pp. 30-31); Vogelkop, M. ochromelas 
apparently at higher elevations, M. leucostephes (rufocrissalis super- 
species) apparently at lower elevations. ‘The Herzog Mountains, most 
of the Eastern Highlands, the eastern Snow Mountains (Mt. Goliath), 
and the northern slope of the Snow Mountains may have initially sup- 
ported M. belfordi and M. rufocrissalis, but what one now finds is a 
hybrid population in the Herzog Mountains (“M. b. stresemannv’), 
most of the Eastern Highlands, and Mt. Goliath (“M. b. griseirostris’”’) 
(Mayr and Gilliard, 1952c), and nearly pure M. belfordi with only a 
few signs of rufocrissalis genes on the northern slopes of the Snow 
Mountains (Gilliard, 1959b, p. 8). Only M. belfordi was reported 
from the Wissel Lakes (Junge, 1963, p. 70), and only M. ochromelas 
from the Wandammen Peninsula (Hartert, 1930, p. 46), but in both 
cases the ornithological survey was not intensive and an additional 
species might have been present but overlooked. Wherever M. belfordi 
coexists with either of the other two species, it occupies the higher 
elevations. M. ochromelas lives below the representative of the rufocris- 
salis superspecies on the Huon Peninsula but possibly above the 
Vogelkop representative. 

While there are other examples of checkerboard allopatry and of 
altitudinal exclusion among New Guinea birds, the case of the mid- 
montane forest Melidectes is unique in two respects. First, there is 
no other instance of a species pair in which the altitudinal sequence 
in one area is inverted with respect to another area, comparable to the 
apparent relations of M. ochromelas and the rufocrissalis superspecies 
on the Huon Peninsula and Vogelkop. Second, except among the al- 
pine Melidectes I am unaware of another instance of compound 
checkerboard allopatry such that each area supports two species of a 
group of three, with the identity of the missing species showing ir- 
regular geographical variation. This situation stems ultimately from 
the facts that the forest Melidectes are too similar ecologically to co- 
exist except by altitudinal exclusion; and that altitudinal series of 
three species in New Guinea are unstable and often lead to the elimi- 
nation of one bird (cf., p. 34). The unique complexity of the Melidectes 
situation may be in part responsible for its providing the only instance 
of hybridization in a New Guinea altitudinal sequence outside the 
family Paradisaeidae.

population as a new race gilliardi, based on size characters of material 
collected by Gilliard. Mayr and Gilliard (1954, p. 507, Hable 7) nad 
already published critical comparative measurements of this material 
and concluded that it did not warrant separation from nominate 
Juscus, a decision also adopted by Sims (1956, p. 432) in treating Shaw- 
Mayer's material. The western population occidentalis is smaller than 
the southeastern population fuscus, and the geographically intermedi- 
ate Eastern Highlands population is intermediate in wing, tail, culmen, 
and tarsus measurements. Since gilliardi overlaps fuscus in all four 
measurements in both sexes except apparently in the culmen of males, 
and since no differences other than size separate the populations, gil- 
liardi should be considered synonymous with fuscus. 


DISCUSSION. Gilliard, Shaw-Mayer, and Schodde collected this 
honeyeater at 10,000-11,000 ft on Mts. Hagen, Wilhelm, Giluwe, and 
Kubor in moss forest below timberline, but I failed to find it on Mt. 
Michael. It gleans, darting rapidly and hopping along branches, from 
the crowns to the understory, is frequently netted, and does not con- 
gregate in flowering trees. 

VOICE. ‘The long, monotonous song is based on a pair of high- 
pitched notes, the second either trilled or slurred and at a lower pitch 
than the first. ‘(he pair is repeated 90 times per minute for 1 min or 
more. The song of Melidectes (“Vosea’) whitemanensis is similar but 
involves only 3-8 repetitions.

In the Snow Mountains M. princeps is represented by M. nouhwyst, 
but there is no member of the superspecies in southeastern New 
Guinea. Only four other species and superspecies (p. 46) are known 
from elevations above 5,000 ft in the Snow Mountains and the Eastern 
Highlands but not from southeastern New Guinea. Rand and Gilliard 
(1967, p. 546) suggest that the absence of the M. princeps-M. nouhuyst 
superspecies from southeastern New Guinea might be due to “perhaps 
the annual burning of the alpine grasslands there, which has destroyed 
the alpine shrubbery and has eaten into the forest, artificially lowering 
the timberline”. This or other explanations involving some general 
ecological condition seem to me improbable because no other wide- 
spread timberline species or superspecies is missing in southeastern 
New Guinea, whereas three are missing in the Eastern Highlands. 
The alternative interpretation I suggest is that the alpine zone in 
New Guinea provides only two Melidectes niches, as shown by the 
distributional evidence (p. 388); and that the establishment of M. 
fuscus and M. belfordi in southeastern New Guinea therefore left no 
room for M. princeps.

DISCUSSION. M. belfordi remains in the crowns, is rarely netted,

branches or up the trunk, often leaning head downwards. Its distribu- 
tion is discussed on pp. 388-389 and pp. 393-396.

to 34 times. I heard similar duets from the related M. ochromelas in 
southeastern New Guinea and M. rufocrissalis in the Eastern High- 
lands. The similarity of these antiphonal duets of three Melidectes 
species to the antiphonal duet of the Giant Fijian Honeyeater, Gymno- 
myza viridis (Diamond, 1972) supports the postulated relationship of 
these two genera (Mayr, 1944).

race from the southern slopes of the Eastern Highlands. ‘The nomi- 
nate race lives in the Schrader Range. 


DISCUSSION. On Mt. Karimui population structure varied with 
altitude in the usual fashion. Zone 2 yielded females and one male 
with tiny testes, and Zone 3 yielded only females. From Zone 4 up- 
ward males were common, and all without exception had enlarged 
testes. One of the females in Zone 5, and both in Zone 6, had enlarged 
ovaries. 

In my collecting areas M. r. thomasi ranged up to 8,000 ft and down 
to a lower limit varying locally between 4,000 ft (Mt. Karimui) and 
6,000 ft (Mt. Michael). Bulmer found M. rufocrissalis x M. belfordi 
hybrids down to about 5,000 ft in Kyaka territory, Bulmer and Gilliard 
found M. rufocrissalis down to 5,000 ft in the Schrader Range, and 
Mackay (N.G.B.S. Newsletter, No. 28, p. 3, Feb. 1968) found it common 
at Pureni near ‘Tari. 

The habitat of M. r. thomasi is the forest and the forest edge, includ- 
ing partly cut forest with small gardens intruding, but not isolated 
groves in open areas, a niche left to M. torquatus. Within this habitat 
and altitudinal range it is not only one of the noisiest but also one of 
the most abundant birds, as the following census figures on Mt. Kari- 
mui show: Zone 2, 2.3%, ot the local avitauna; Zone 3, 3:99; Zone 44 
S49; Zone 5, 27%; Lonel, loo%,; Zone 7; no records; Zones, Lot 
It remains in the middle- and upperstory, with the result that only two 
of the specimens were collected with nets. Noisy chases between sev- 
eral birds in the treetops were a common occurrence. It was the 
largest of the several kinds of honeyeaters attracted to the flowering 
trees at 4,450, 4,700, and 6,430 ft on Mt. Karimui. 

VOICE. The loud vocalizations include: a series of hoarse “caws”’ 
on the same pitch, similar to Lophorina superba but with no decelera- 
tion; and a series of two kinds of notes strictly alternating with each 
other, one note clear and on a slightly higher pitch, the note immedi-

ately preceding and following it more complex. This latter call is so 
similar to the common call of M. torquatus as to be not safely distin- 
euishable. There is also a duet of alternating caws (Diamond and 
Terborgh, 1968, p. 74), similar to that of M. belfordi. 


Melidectes belfordi & Melidectes rufocrissalis hybrids 


The problem of hybridization between these two species in the 
Eastern Highlands was recognized and greatly clarified in the studies 
of Mayr and Gilliard (1952c) and of Gilliard (1959b). Additional dis- 
coveries since Gilliard’s 1959 paper shed new light on the problem. 

The starting point of Mayr and Gilliard’s studies was that one 
finds in the Wahgi region hybrid swarms containing individuals close 
to pure M. rufocrissalis, others close to M. belfordi, and a whole 
spectrum of intermediates. At higher elevations (> 8,000 ft) these 
hybrid populations gradually yield to typical M. belfordi. Material 
collected earlier in the Herzog Mountains (“M. b. stresemannv”’) and 
on Mt. Goliath (“M. b. griseirostris”) was also very variable and evi- 
dently represented hybrid populations with a preponderance of 
belfordi genes. Subsequently (in 1954) Gilliard obtained 12 specimens 
at ‘Telefolmin (northern watershed), of which seven were nearly pure 
belfordi, three nearly pure rufocrissalis, and two hybrids. Pure M. 
rufocrissalis had previously been known only from the type locality 
of the Schraderberg on the northern watershed. 

The four newer findings are as follows: 

1. Melidectes honeyeaters on Mt. Karimui, at Okapa, and on Mt. 
Michael (all in the southern watershed) proved to belong to a new 
face of M. rufocrissalis, M. 7. thomas (Diamond, 1967a, p. 9; 1969, 
p. 55), identical to M. r. rufocrissalis except that the forehead was 
black, not white. Since a black forehead is a belfordi character that 
tends to predominate in the hybrid swarms, the origin of M. r. thomasi 
was probably a hybrid one. However, M. r. thomas: differed from the 
other hybrid swarms and hybrid races in being uniform and showing 
no other belfordi traits, suggesting that the hybridization leading to 
M. r. thomasit had occurred considerably earlier and that other 
belfordi genes had been eliminated. Since the southern watershed of 
the Eastern Highlands remains little explored ornithologically above 
3,000 ft from Mt. Karimui for 300 miles westwards to the Star 
Mountains, and since M. rufocrissalis has been observed near Tari 
140 miles west of Mt. Karimui, the new race may have an extensive 
range. 

2. ‘Iwo specimens collected in the Star Mountains on the southern 
watershed were discussed by Mees (1964, pp. 26-27). Of the one col- 
lected at the lower elevation (ca. 4,000 ft), he reported, “This specimen 
has all the characters of M. rufocrissalis, except that the supercilium is 
yellow.” Of the one collected near 6,000 ft: “This bird agrees with M. 


393 


SPECIES ACCOUNTS 


belfordi, except that the bill is much larger and grayish in color. The 
feathers over the eye are white. These two characters point to hybrid- 
ization with the next species [M. rufocrissalis].’ Actually, the super- 
cilium is yellow in pure rufocrissalis and white in pure belfordi, so that 
the rufocrissalis specimen was in fact pure and the belfordi one nearly 
SO. 

3. In 1966 I found that no species of genus Melidectes was present 
in the North Coastal Range (Prince Alexander Mountains, Torricelli 
Mountains, Bewani Mountains) although the maximum altitudes in 
the North Coastal Range (up to 6,200 ft) were high enough for several 
of the species. In 1959 Gilliard had found no Melidectes species in 
the Adelbert Mountains, perhaps because they rise only to ca. 4,500 ft. 
Mayr had also found no Melidectes in the Cyclops Mountains, which 
rise to-7, LOO) it. 

4. In 1963 and 1964 Bulmer (pers. comm.) and Gilliard (Gilliard 
and LeCroy, 1968, pp. 33-35) discovered a population of M. belfordi 
in the Schrader Range of the northern watershed, the type locality of 
M. r. rufocrissalis. M. belfordi lived alone in the beech forest above 
7,500 ft, M. rufocrissalis lived alone in the forest and disturbed areas 
below 7,000 ft, and the two species overlapped only in a narrow band 
at 7,500-8,000 ft. Most specimens were pure, but a few showed signs 
of hybridization. 

‘Two major problems, in addition to a host of minor ones, remain 
unsolved. Why and how long has hybridization been occurring? Where 
did M. rufocrissalis and M. belfordi originate? 

Regarding the origin of hybridization, Gilliard (1959b) suggested that 
it might stem from the extensive habitat disturbance caused by native 
agriculture. ‘The evidence for altitudinal exclusion in undisturbed 
habitats, and the wholesale hybridization in the extensively dis- 
turbed Wahgi Region, are in general accord with this suggestion. If 
this hypothesis is correct, massive hybridization may have started only 
a few centuries ago. Information as to whether any hybridization at all 
takes place where both species occur together in completely undis- 
turbed areas is sorely lacking. I would guess that some hybridization 
has been going on for a long time in undisturbed areas in the very 
narrow band of altitudinal overlap, since M. +. thomasi is a uniform 
and presumably not recent race even in the virgin forest of Mt. Kari- 
mui; and that habitat disturbance has drastically accelerated hybridiza- 
tion by creating much larger zones of contact. 

Regarding the evolution of the group, Gilliard suggested “that wat- 
tle birds [the M. rufocrissalis superspecies] are essentially forest-edge 
birds of the northern watershed and that the black bills [M. belfordz] 
are essentially pure forest birds of the central range and southern 
watershed” (Gilliard, 1959b, p. 24). In particular, he suggested, the 
M. rufocrissalis group might have originated on the “north moun- 
tain islands” (Huon Peninsula, Adelbert Mountains, North Coastal 


394 


SPECIES ACCOUNTS 


Range, Cyclops Mountains, and Van Rees Mountains) north of the 
Mamberano-Sepik-Ramu-Markham gulch and might have reinvaded 
the central range. While this hypothesis accounted for the facts avail- 
able before 1959, it is untenable in the light of the more recent evi- 
dence. M. rufocrissalis has at least as extensive a range on the southern 
watershed (Okapa to the Star Mountains) as on the northern water- 
shed (Huon Peninsula to Telefolmin); M. belfordi coexists with M. 
rufocrissalis at its type locality on the northern watershed; and three 
of the four “north mountain islands” explored to date (Adelbert 
Mountains, North Coastal Range, and Cyclops Mountains) lack not 
only M. rufocrissalis but any member of genus Melidectes. M. rufo- 
crissalis’s habitat is primarily the lower altitudes and only incidentally 
the forest edge; it simply happens that the forest edge habitats created 
by native agriculture lie mainly in its altitudinal range because the 
range of M. belfordi is mostly too high for agriculture. Finally, analy- 
sis of New Guinea bird distributions suggests that colonization across 
the Mamberano-Sepik-Ramu-Markham gulch by midmontane birds 
has been practically a one-way affair, i.e., that the large Central Range 
has provided many midmontane species to colonize the small “north 
mountain islands” but that reverse movement of midmontane birds 
has been almost nonexistent. 

Most pairs of New Guinea montane birds with mutually exclusive 
altitudinal ranges seem to have originated as eastern and western 
populations of a polytypic species on the Central Range (p. 34), and 
this was presumably the case in the M. ochromelas-M. belfordi-M. rufo- 
crissalis group as well. ‘There are more marked differences among the 
semispecies of the rufocrissalis superspecies than among the subspecies 
of M. ochromelas or among the subspecies of M. belfordi, but the dif- 
ferences between M. belfordi, M. rufocrissalis, and M. ochromelas are 
greater than those within the rufocrissalis superspecies. Morpholog- 
ically, M. rufocrissalis is no closer to M. belfordi than M. ochromelas 
is to either, and one probably could not have predicted a priori in 
which of the three cases (M. ochromelas-M. belfordi, M. ochromelas- 
M. rufocrissalis, M. belfordi-M. rufocrissalis) isolating mechanisms 
were most likely to break down. While reconstruction of the evolu- 
tionary history inevitably involves some guesswork, the simplest ex- 
planation of these facts is that the common ancestor first broke up 
into three allopatric populations, the ancestors of M. belfordi, M. rufo- 
crissalis, and M. ochromelas; and that M. rufocrissalis was the first to 
expand, reinvaded the ranges of the other two species by displacing 
them altitudinally, and then differentiated geographically. ‘The per- 
ipheral distribution today of M. ochromelas may indicate that it was 
the second to expand, reaching the mountains of the Huon Peninsula 
and Vogelkop, which M. belfordi as the last species to expand may 
not have had time yet to colonize. Present-day distributions would owe 
their final form to the instability of three-species altitudinal sequences,

causing the extinction of M. rufocrissalis in some areas (southeastern 
New Guinea, Weyland Mountains, southern slope of the Snow Moun- 
tains) and of M. ochromelas in others (Eastern Highlands and northern 
slope of the Snow Mountains).

TAXONOMY. In color these match a single male of M. t. poly- 
phonus from Wau (Herzog Mountains), which has a wing of 116 mm. 
Mayr’s (1931, p. 660) measurements of his type series of polyphonus 
(2s 3.123, amd? 125, 1 or 113) are larger than my series, six males 
which I measured from Gilliard’s Wahgi series (115, 116, 117, 117, 
119, and 123), or Gyldenstolpe’s (1955, p. 164) Wahgi series (6 ¢, 110- 
121, 8 ¢, 103-111, according to his measurements). ‘The races torqua- 
tus, nuchalis, mixtus, and cahni are all paler and less ochraceous be- 
low, while emilii is more ochraceous below, has larger throat wattles, 
and the white throat patch reduced in size. 


DISCUSSION. ‘This species and Gerygone ruficollis are probably 
the midmontane birds which have profited most greatly from the 
activities of man. My only records from undisturbed forest were 
of the two Mt. Karimui specimens (4,400 ft) and of several seen at 
the Sena River (4,500 ft). In undisturbed forest in other parts of New 
Guinea as well (e.g., southern slopes of the Snow Mountains, Iden- 
burg slopes) it seems rare, to judge from other expedition reports. In 
settled and cleared midmontane areas, however, both in the Eastern 
Highlands and in the Baliem Valley of western New Guinea it is 
very common in trees of gardens, the forest edge, open second-growth, 
and casuarina groves up to 5,500 or 6,000 ft. ‘he lower limit may be 
somewhere around 3,500 ft, since it was uncommon at Okasa (3,550- 
4,250 ft) and sighted only a few times at Karimui (3,650 ft), despite 
plenty of forest edge habitat in both areas. ‘Testes were large in three 
Awande males but tiny in all three Okasa males, suggesting that Okasa 
may be supporting immatures at the lower fringe of the range. 

Melidectes torquatus is usually seen in trees 15 ft or more above 
the ground, though two were netted at the forest edge. ‘he Karimui, 
Sena River, and Mt. Karimui records were all from flowering trees. 
At Miarosa Terborgh found M. torquatus accounting for 90°% of 
the bird-usage in a tree with a hard-shelled fruit that had been chipped 
open by the parrot Trichoglossus haematodus (ct., p. 143).

STOMACH CONTENTS. Fruit, 2-8 mm in diameter (14 stomachs); fruit and 
insects (four); insects (one), 

TAXONOMY. Among the adults there is no more than a slight 
increase of wing length with altitude on Mt. Karimui. ‘There are no 
average differences in the darkness of the underparts or upperparts 
between birds from the lowest zones of Mt. Karimui, from the highest 
zones of Mt. Karimui, and from Awande. These Eastern Highlands 
birds average slightly darker and blacker above than topotypical 
goliathi from Mt. Goliath or from the northern slopes of the Snow 
Mountains, and more so compared to nominate fumigatus of south- 
eastern New Guinea, though the difference in blackness may involve 
foxing (Gilliard and LeCroy, 1961, p. 76). Birds from higher altitudes 
(> 8,000 ft) on Mt. Hagen and in the Snow Mountains have consider- 
ably longer wings (¢ 120-128, 9 108-117) and, at least on Mt. Hagen, 
have darker breasts and lighter bellies. 

DISCUSSION. ‘The population structure deduced from details of 
gonad condition and from weights and wing lengths is as follows. At 
the bottom of the altitudinal range are immatures: a male with tiny 
testes at Okasa, two specimens with very short wings (102) and undis- 
cernible gonads at Karimui, and three males with short wings (100, 
102), low weights (46, 49), or tiny testes in Zone 2 of Mt. Karimui. 
The first adult males and females appear in Zone 2, but males with 
enlarged testes do not appear until Zones 5 and 6 (ca. 6,000-7,000 ft) 
of Mt. Karimui and at Awande (6,000 ft). Zones 7 and 8 (7,080-8,165 
ft) contain largely or solely females. 

Melipotes fumigatus is one of the commonest Eastern Highlands 
forest birds from about 4,000 to 11,200 ft. Below 4,500 or 5,000 ft one 
usually finds only immatures in low numbers, but in the main part 
of its altitudinal range (e.g., Zones 2 through 8 of Mt. Karimui) it 
accounts for about 3.59% of the local avifauna. It remained common 
through the stunted moss forest both on Mt. Karimui (6,500-8,165 ft) 
and on Mt. Michael (8,700-11,200 ft), and disappeared on Mt. Michael 
only where the moss forest gave way to alpine grassland. It also ex- 
tends to timberline in western New Guinea, but not in southeastern

SPECIES ACCOUNTS 


New Guinea. In behavior Melipotes fumigatus is silent, slow-moving, 
and solitary, and observed much less often than one might have ex- 
pected from its abundance. In the forest interior it remains mainly in 
the middle- and upperstories, but it often descends to the understory 
at the forest edge. It is the only forest honeyeater at higher elevations 
whose diet is mainly (but not solely) fruit. Several individuals were 
collected in the flowering tree at 6,500 ft on Mt. Karimui, but these 
were probably seeking insects attracted to the flowers rather than the 
flowers themselves (Mayr “and Rand, 19377, pv 221). 


VOICE. On only one occasion during four expeditions to areas 
where Melipotes fumigatus was abundant have I heard a sound from 
it: a series of a half dozen identical, rather slow, high-pitched, not loud 
notes, upslurred at the end and with a quality as of sleighbells or 
some parrots (e.g., Domicella lory).

STOMACH CONTENTS. Insects (two stomachs); fruit (two). 

TAXONOMY. ‘The dorsal coloration is deep glossy violet. ‘The 
races rubrigulare and albopunctatum on the Fly River have the red 
throat patch of the male larger. 

BREEDING. ‘Testes were enlarged in four males, not enlarged in 
three others. 

DISCUSSION. ‘This inconspicuous, tiny flowerpecker occurred at 
all my collecting localities up to 5,700 ft in forest and up to 6,200 ft in 
cultivated areas. Single individuals, occasionally pairs, ranged from 
the treetops to 10 ft above the ground. I never netted the species. 

VOICE. ‘The two inconspicuous and quite different calls usually 
provide the only evidence for the presence of the species in forest. One 
is a short, dry, buzzy, insect-like note. ‘The other is a high, sibilant 
upslur confusingly similar to the call of the sunbird Nectarinia sericea. 
However, the sunbird’s call is usually repeated, whereas that of 
Dicaeum is given once.

TAXONOMY. There appears to be a slight increase in size with 
altitude, as suggested by the following measurements of adult males. 
In each case the average wing length is given first, then the average 
tail length, then the weight: Soliabeda (1,350-2,000 ft), 65.6 mm, 45.8 
mm, 12.2 g; Karimui (3,650 ft), 67.0 mm, 46.9 mm, navies 

As in the case of M. versteri, females and immature males are heavier 
than adult males, though the difference is less marked in the case of 
M. nigra. 

The race unicolor of northern and southeastern New Guinea is 
entirely blue-black in the adult male and differs strikingly from the 
races chloroptera and nominate nigra of southern and western New 
Guinea and from my series, in which the male’s underparts are gray. 
Nigra lacks the olive edges on the remiges of the male, present in my 
series and in chloroptera. The only color difference between my series 
and chloroptera from the Aru Islands, Fly River, and southwestern 
New Guinea is that Karimui males average very slightly darker below 
and that this is somewhat more pronounced at Soliabeda. As seen in 
Table 18, my specimens have wings and tails as long as in southeastern 
New Guinea wnicolor, slightly longer (particularly in the female) than

topotypical chloroptera from the Aru Islands, which are in turn 
shehtly larger than the Fly River and southwest New Guinea popula- 
tions. ‘he Lake Kutubu population also belongs to chloroptera and 
has essentially the same measurements as the Karimui series. 

The racial assignment of the Karimui population is of interest from 
an evolutionary point of view. The genus Melanocharis contains a 
triple altitudinal sequence: M. nigra in the lowlands to 3,000 or 4,000 
ft, M. longicauda from the upper limit of M. nigra to about 5,000 ft, 
and M. versteri from the upper limit of M. longicauda to near timber- 
line. Subspecific variation is much less marked in M. longicauda and 
M. versteri than in M. nigra, suggesting that M. nigra is the oldest 
form, isolates of which have in the past reinvaded each other’s ranges 
with altitudinal displacement to give rise to the other two species. 
The color difference between the black-bellied males of M. nigra wnt- 
coior and the gray-bellied males of the other M. nigra races is more 
striking than the differences between these gray-bellied races and the 
other two species. ‘The songs of the black-bellied and gray-bellied races 
are detectably different to my ear. ‘The black-bellied and gray-bellied 
populations must meet somewhere on the eastern shore of Geelvink 
Bay on the north coast and somewhere on the Gulf of Papua on the 
south coast. 

On the north coast the gray-bellied race M. n. nigra has been taken 
as far east as the Wanggar River at the head of Geelvink Bay, while 
the black-bellied race wnicolor has been taken as far west as Pionier- 
bivak on the Mamberano River, leaving an uncollected gap of 180 
miles between these two localities on the New Guinea mainland. Japen 
Island, which lies about 15 miles offshore in this gap, is the type 
locality of wnicolor. On the south coast unicolor is known as far west 
as Hall Sound, and chloroptera was previously known as far east as 
Sturt Island on the Fly River. ‘The finding of chloroptera at Karimui 
extends its range 200 miles farther east to within 100 miles of wnicolor. 
When further ornithological exploration closes these two gaps, it will 
be interesting to examine whether the black-bellied and gray-bellied 
races finally intergrade in the short remaining unexplored distance 
or whether they behave as good species, furnishing a model for the 
evolution of M. longicauda and M. verstert. 


BREEDING. Gonads were small in almost all specimens. 


DISCUSSION. M. nigra is a common but inconspicuous species 
(about 2% of the local avifauna in the Karimui area) which is heard 
or netted much more often than it is seen. Individuals, pairs, or 
eroups of up to six flit rapidly through the forest or second growth 
2-20 ft above the ground. Adult males, adult females, and immature 
males spend the same proportion of the time in the understory, as 


judged by netting results. On Mt. Karimui, where M. longicauda was

absent, M. nigra occurred up to 4,300 ft, above which elevation it was 
replaced by M. versteri. At Okasa, where M. longicauda was present, 
collections down to 3,550 ft failed to yield M. nigra. 

VOICE. The distinctive song is a very rapid series of thin twitter- 
ing notes whose pitch describes a perfect sine wave (Fig. 42). ‘There 
are up to two waves per second and more than a half dozen waves 
per song. The call is a weak, brief, formless, slightly buzzy twittering 
somewhat reminiscent of Peltops montanus in quality.

TAXONOMY. My specimens as well as three collected by Gilliard 
in the Wahgi Valley clearly belong to the race captata of the Huon 
Peninsula, with which they agree in the pattern of white on the tail; 
the outer edge of the outermost tail feathers is white, broadened dis- 
tally into a bar, as illustrated by Salomonsen (1960). The race ori- 
entalis of southeastern New Guinea, to which previous collectors 
tentatively assigned their more limited material, differs in having a 
smaller white spot distally. 

BREEDING. Gonads were small in all specimens. 

DISCUSSION. ‘This species is best distinguished from its congeners 
by the yellowish wash of the underparts, the lemon pectoral tufts, and 
the tail length (longer than M. nigra, shorter than M. versteri). It 
forms the middle member of a three-species altitudinal series with 
M. nigra and M. verstert, both of whose altitudinal ranges it overlaps 
slightly, and is local and uncommon, as are the middle members of

other series. The only localities where it was common were Okasa and 
Mengino, where the other two species were absent. It was outnumbered 
by M. nigra at Bomai and by M. versteri at Awande, and was missing 
(squeezed out—see p. 34) on Mt. Karimui. M. longicauda and Coracina 
morio were the only two bird species (both of them characteristic of 
hill forest) which were present at Bomai (3,250 ft) but absent at 
Karimui Patrol Post (3,650 ft). 

Both at Okasa and at Mengino Terborgh observed M. longicauda 
in trees bearing small fruits. 


VOICE. At Okasa Terborgh heard this species delivering a “‘sine- 
wave’ song similar to that of M. nigra (Fig. 42), suggesting that voice 
is not the isolating mechanism between these two sibling species. The 
calls include a high-pitched twittering, and incessant sibilant notes.

STOMACH CONTENTS. Fruit 2-5 mm in diameter (11 stomachs), fruit and 
insects (two), insects (one). Most stomachs of netted birds were empty, suggesting 
that digestion is rapid. 

TAXONOMY. This is one of the few passerine species in which 
the female is larger than the male. All females I examined have heavier 
weights, and all but one have longer wings, than all adult males 
examined, though the males have longer tails. Immature males in 
female-like plumage are intermediate in weight and wing length be- 
tween adult males and females but have the short tails of the females. 
As they mature, not only must males lose weight, but also their wings 
must become shorter, as also true of Serzculus aureus (Diamond, 1969). 
The four immature males with the longest tails (70-72) have nearly 
acquired the clear gray underparts of the adult male, though they 
still have female-like olive upperparts. 

Eastern Highlands males are slightly darker gray below than 
maculiceps from southeastern New Guinea, less dark than nominate 
versteri of the Vogelkop or Cyclops specimens included in virago, and 
still less dark than meeki of the Weyland and Snow Mountains. East- 
ern Highlands females are darker and grayer below, less yellow, than

SPECIES ACCOUNTS 


maculiceps and are close to a single topotypical female virago from the 
Schraderberg. 

BREEDING. On Mt. Karimui testes were somewhat enlarged in 
almost all adult males and in half of the immature males in female- 
like plumage but were not greatly enlarged in any specimen. 

DISCUSSION. Melanocharis versteri, the highest species in the 
M. nigra-M. longicauda-M. verstert altitudinal sequence, is common 
but quite inconspicuous within its altitudinal range in forest and 
dense second-growth. On Mt. Karimui, where M. longicauda was ab- 
sent, M. verstert descended to 4,500 ft and was common (4% of the 
local avifauna) up to the summit at 8,165 ft. At timberline it goes out 
to tree ferns in alpine grassland near the forest edge. Much of its 
time was spent in the lowerstory, but in fruit trees it occasionally 
ranged up to 40 ft above the ground. Females, adult males, and im- 
mature males were netted with the same frequency. Once I saw an 
adult male hovering at flowers. 


VOICE. A variety of faint and high-pitched notes, such as a thin, 
rapidly repeated “‘ts-ts. ...”; a scratchy and complaining ‘“‘dee-dee-dee’’; 
a high-pitched nasal “ee’’; and an upslurred inquiring ‘“‘chee-chee- 
chee”. All these notes are faint, unlikely to catch one’s attention, and 
not distinctive.

WING. 12 4: 69-75 (72.2415). 8 9: 71-75 (72.9+1.1). 

TAXONOMY. Females have slightly heavier weights and longer 
wings than males, but the difference is much less marked than in the 
case of M. verstert. 

‘These specimens agree well with topotypical striativentris from the 
southern side of southeastern New Guinea. The race prasina of the 
northern side of southeastern New Guinea differs in having the basal 
portion of the tail white, while chrysocome of the Huon Peninsula 
is larger, darker ventrally, and more obscurely streaked. 

BREEDING. Gonads were small in most specimens but were 
slightly enlarged in one male and three females. 

DISCUSSION. ‘The most noteworthy feature of this species is the 
extreme local variability of its abundance despite its wide geographical 
range. Ihe American Museum of Natural History has a total of 14 
specimens. Ihe exhaustive collections of the three prewar Archbold 
expeditions included only two specimens of this species. Gilliard

found it uncommon, Shaw-Mayer missed it, and I found it uncommon 
at Mt. Karimui, Okasa, and Miarosa. At Awande, however, one mile 
from Miarosa and 10 miles from Okasa, it proved to be the most 
abundant bird both in 1964 and 1965, and saturated our nets located 
at 6,100 ft just inside the forest near its edge and adjacent to gardens. 
Gyldenstolpe also found it abundant near Nondugl. The altitudinal 
range was 4,750-5,960 ft on Mt. Karimui and about 4,000-6,800 ft in 
the Okapa area, overlapping both M. longicauda and M. versteri (but 
not M. nigra).

TAXONOMY. After comparing my material with specimens from 
other parts of New Guinea, including six topotypical males and two 
females from the Vogelkop, I agree with Salomonsen (1960, p. 3) and 
Gilliard and LeCroy (1970, p. 24) that there is too much individual 
variation to recognize the race bloodi. 

BREEDING. All adult males on Mt. Karimui, and one of the 
immature males in female-like plumage, had the testes considerably or 
ereatly enlarged.

SPECIES ACCOUNTS 


DISCUSSION. ‘This is one of the midmontane species whose alti- 
tudinal range shows local variations apparently correlated with the 
presence of mossy conditions (cf., Ptiloprora guise’). On Mt. Michael, 
where heavy mossing set in at 8,700 ft, Oreocharis was collected at 
8,000 ft. En route from Mt. Michael to Karimui we passed through a 
tongue of moss forest at about 6,000 ft near Agotu and immediately 
re-encountered Oreocharis. On Mt. Karimui, where heavy mossing 
began at 6,500 ft, Oreocharis descended to 4,720 ft but became common 
only above 7,600 ft. In the Okapa area, where no heavy moss was 
encountered as high as we collected (up to 7,000 ft), Oreocharis was 
absent. It was generally in the middle- or upperstory of the forest, in 
flocks, and was rarely netted. Although stomachs contained solely 
fruit, I once saw an individual hanging upside-down to probe a flower.

STOMACH CONTENTS. Fruit, 2-8 mm in diameter. 

DISCUSSION. ‘This flowerpecker is common and widespread in 
high altitude stunted mossy forest, from timberline down to 9,500 ft 
(Mt. Michael) and on the very summit (8,165 ft) of Mt. Karimui. Most 
of its altitudinal range lies above that of its smaller relative Oreocharis 
arfaki. Paramythia montium feeds unsystematically on berries: it flies 
into a tree with a loud wing beat, hops around vigorously, plucks a 
few berries, and flies off again, leaving the tree full of uneaten berries. 
It spends more time in the crowns than in the understory. 


VOICE. A faint squeaky note, suggestive of the sounds made by 
birdwatchers squeaking or sucking on the back of their hands to attract 
birds.

TAXONOMY. ‘The black of the forehead is restricted to a small 
area at the base of the bill and is much more limited than in delicatula 
of the southern slopes of southeastern New Guinea, in which the 
black extends beyond the eyes. In this respect my specimens agree 
with the description of tenuifrons (Greenway, 1935, p. 105; perhaps 
synonymous with chrysolaema) from the northern slopes of south- 
eastern New Guinea, of which I have seen no topotypical material. 


BREEDING. ‘The male had the testes greatly enlarged. 


DISCUSSION. At Karimui and Bomai this hill forest white-eye 
was uncommon (ca. 0.2% of the local avifauna) and was encountered 
in groups of up to four birds in the upperstory of forest and second- 
growth, sometimes in flowering trees. Z. novaeguineae lives at higher 
altitudes, but the ranges may overlap slightly, since Bulmer collected 
both species around 5,000 ft in Kyaka territory.

TAXONOMY. Mayr and Gilliard (1951, pp. 14-15) and Gylden- 
stolpe (1955, p. 176) recognized three races of Z. novaeguineae, two of 
them (wahgiensis and shawmayert) new, within an area 45 miles in 
extent containing no distributional barriers to the species. Examination 
of the unique type of shawmayeri shows that it 1s indistinguishable from 
wahgiensis, as Mees (1961) suspected and as Rand and Gilliard (1967, 
p. 591) and Mayr (1967, p. 309) recently agreed. All Eastern Highlands 
material collected to date belongs to a single thinly differentiated race 
wahgiensis, which differs from crissalis in the slightly darker, more 
ereen, less yellow back and the more gray, less powder-brown abdomen. 
My specimens differ from Nondugl wahgiensis mainly in having a 
slightly brighter yellow throat. 

BREEDING. The gonads of all specimens were small. 


DISCUSSION. Zosterops novaeguineae occurs in flocks in the 
crowns and middlestory, occasionally the understory, of forest at about 
5,000-7,500 ft. It is somewhat commoner in disturbed habitats (casu- 
arina stands, bushes of second-growth).

VOICE. The common call note is a sweet, down-slurred “tsyew” 
with a sharp attack and suggestive of a Lonchura mannikin. ‘This note 
is faint, but the pooled sound of many members of a flock calling at 
once is loud. There is also a short, dry, upslurred, trilled call mote 
similar to that of Zosterops lateralis of New Zealand and Z. hypoxantha 
of New Britain. The lengthy, sweet song of whistles and upslurs 
suggests the song of Saxicola caprata in quality.

becomes locally superabundant when the bamboo produces seed. 
When disturbed, it flies up with a loud whirring of the wings. 

VOICE. The call is a very rapid descending series of 2-5 thin,

papuana, lacking (usually) or present but very small (infrequently) 
in adult males of E. trichroa sigillifera (and in females of both species). 
The stouter bill of adult males of E. papuana is visible at a glance. 
Measurements (‘Table 19) show that all or almost all E. papuana have 
longer wings, longer bills, and heavier weights than all or almost all 
E. trichroa sigillifera. Colors of the soft parts in life were the same for 
my specimens of both species (bill black, eye brown, legs pale flesh- 
brown). 

DISCUSSION. ‘Three specimens were netted in second-growth near 
the forest edge and one shot in the forest at 6,200 ft near Awande. 
The fifth specimen was shot at 4,000 ft in the Okasa forest nine miles 
from Awande. 

The only other records of this rare species are from four localities 
in southeastern New Guinea (Aroa River, Kotoi, Mt. Tafa, Mt. Albert- 
Edward), from the Wissel Lakes of western New Guinea, and from the 
Arfak and ‘Tamrau Mountains of the Vogelkop. The distributional 
relationship with the widespread and much commoner E. trichroa 
sigillifera can be described approximately as checkerboard allopatry. 
In the Okapa area (4,000 and 6,200 ft) I obtained only E. papuana, 
while elsewhere in the Eastern Highlands (3,500-9,200 ft: Karimui, 
Mt. Karimui, Mt. Kubor, Mt. Wilhelm, Mt. Hagen, Mt. Giluwe, 
Wahgi Divide Mountains, Weiga, Schraderberg, Baiyer Valley, Kaironk 
Valley) other collectors and I obtained only E. trichroa. In southeastern 
New Guinea the First Archbold Expedition collected E. papuana on 
the east slope of Mt. Tafa, E. trichroa on the west slope of Mt. Tafa and 
at three other localities. At the Wissel Lakes and at Bon Kourangen 
in the ‘l'amrau Mountains only E. papuana was taken. ‘There are only 
two instances of local sympatry: both species were recorded at Mayr’s

locality of Siwi in the Arfak Mountains of the Vogelkop; and on Mt. 
Albert-Edward in southeastern New Guinea I found E£. trichroa abun- 
dant at 6,000-9,200 ft, E. papuana at 5,000-6,000 ft. No differences in 
habitat preference, altitudinal preference, or behavior have been noted, 
except for the altitudinal segregation on Mt. Albert-Edward. Both 
forms inhabit forest and the forest edge from about 3,000 to 7,000 ft 
(E. papuana) or 9,000 ft (E. trichroa). Unlike the situation among the 
Geospiza finches of the Galapagos Islands, the difference in bill size 
of these mannikins is evidently not sufficient to permit local overlap. 
E. papuana is endemic to New Guinea and presumably is the older 
invader, while E. trichroa extends from Celebes to Micronesia. ‘The 
relict distribution of E. papuana suggests that its congener is in the 
process of replacing it and that it has been able to hold out only at a 
few scattered localities. 


Lonchura grandis grandis (Sharpe) 
Great-billed Mannikin 


SPECIMENS EXAMINED. Okasa: 1 9 (26 June 1965). 

WEIGHT. 16. 

WING. 56. 

TAXONOMY. The specimen has a duller back, a duller and more 
yellow-edged tail, and paler brown flanks than nominate grandis from 
southeastern New Guinea. However, it can be matched by some speci- 
mens of grandis in the first two respects and is approached by some 
grandis in the third respect. The race ernesti has the edges of the 
rectrices still paler, duller, yellower, and less ochraceous, while heurni 
has the back richer chestnut. 


DISCUSSION. In 1964 I observed a flock of five of this species at 
4,200 ft in the extensive grasslands surrounding the Okasa forest. In 
1965 L. spectabilis, the widespread Lonchura of the midmontane grass- 
lands in the Eastern Highlands, was the common form at Okasa, and 
only the single specimen of L. grandis was obtained. Mixed flocks con- 
taining both species were never observed. 

Examination of the distribution of Lonchura mannikins in the mid- 
montane grasslands of New Guinea proves interesting. Extensive mid- 
montane grasslands probably came into existence only within the past 
millenium, as a result of native agriculture, and must originally have 
been confined to very narrow strips along a few of the larger lakes and 
rivers, and perhaps landslide areas. A total of eight species of Lonchura 
may now be found in the midmontane grasslands in various parts of 
New Guinea. Of these eight, two are localized species (L. vana and 
L. teerinki) endemic to this habitat; five are lowland species (one, L. 
caniceps, confined to southeastern New Guinea; the other four—L. 
tristissima, L. grandis, L. castaneothorax, and L. spectabilis—wide- 
spread) that appear to have spread upwards to the new habitats as

they were created; and the eighth, L. montana, an alpine species that 
has spread downward. Apart from Okasa in the Eastern Highlands 
(L. grandis and L. spectabilis) and Mafalu in southeastern New Guinea 
(L. grandis and L. caniceps), each midmontane locality supports only 
a single species, but the identity of the locally successful colonist varies 
in an unpredictable checkerboard fashion over New Guinea. An 
extreme example of this irregularity occurs in the Herzog Mountains, 
where four different colonists occur at four different localities within 
35 miles: L. tristissima in the Snake River Valley, L. castaneothorax 
at Mumena Creek, L. grandis at Biolowat, and L. spectabilis at Wau. 
The details for the rest of New Guinea, proceeding east to west, are 
as follows: southeastern New Guinea, L. caniceps (plus L. grandis at 
Mafulu); Herzog Mountains, cited in previous sentence; Huon Penin- 
sula, L. tristissima at some localities, L. spectabilis at others; Adelbert 
Mountains, L. tristissima; Eastern Highlands, L. spectabilis (plus L. 
grandis at Okasa); ‘Vorricelli Mountains, L. tristisstma; Baliem Valley 
of the Snow Mountains, L. teerinki; Ilaga Valley of the Snow Moun- 
tains, L. montana; Wissel Lakes, L. castaneothorax; Weyland Moun- 
tains, L. tristissima; Anggi Lakes of the Vogelkop, L. vana; other 
localities in the Vogelkop, L. tristissima. As discussed on p. 40, this 
checkerboard pattern probably reflects the facts that the midmontane 
grasslands provide islands of suitable habitat for the Lonchura man- 
nikins, that establishment of the first successful colonist prevents the 
establishment of later potential colonists, and that it is in part a 
random matter which species arrives first.

TAXONOMY. L. s. wahgiensis is the widespread Lonchura of the 
midmontane grasslands west at least to ‘Tari and east at least to the 
Okapa area, with the underparts whitish (sometimes pale buff in 
adults and medium buff in immatures). L. s. gajyduseki is a distinctive 
form confined to the Karimui Basin, with the underparts medium 
buff in both adults and immatures (see Diamond, 1967a, p. 15, for 
diagnosis).

BREEDING. The testes of all adult L. s. gajduseki were much 
enlarged, indicating synchronized breeding activity in the dry season. 

DISCUSSION. Flocks of up to 30 individuals are seen between 
3,000 and 8,000 ft in the Eastern Highlands at any locality where there 
are large expanses of medium-tall grassland. Unlike L. tristissima, 
which sometimes perches in bushes and trees at the forest edge or in 
second-growth, L. spectabilis seems quite unable to utilize forest edge 
habitats. My general impression of New Guinea Lonchura species 
(with the possible exception of L. tristissima) is that they are among 
the last grassland birds to colonize a new garden or airstrip carved out 
of the forest and appear only when the available area of grassland is 
substantial, possibly because of their inability to use the forest edge 
and their need to associate in large flocks. 

The presence of two endemic midmontane races of Lonchura 
spectabilis raises some evolutionary problems (see pp. 76-77). These 
problems are less acute in the case of L. s. wahgiensis, which differs 
only slightly from L. s. mayri of the lowlands and now has a large 
midmontane range, extensive parts of which have probably been under 
cultivation for at least several centuries. ‘This timespan and the slight 
racial differences make it plausible that wahgiensis could have evolved 
in the last few centuries. An alternative hypothesis is that it may be 
much older and may have eeked out a precarious existence along the 
edge of the Wahgi and other rivers prior to extensive native agri- 
culture (cf., Rand and Brass, 1940, p. 377; Rand, 1941b). 

L. s. gajduseki is more distinct and inhabits a much smaller range 
with a well-known recent history. Information given by natives sug- 
gests that the Karimui Basin has been inhabited somewhat less than a 
century. Originally the natives’ diet was mainly sago, and dependence 
on gardens began only with the termination of intertribal warfare 
and the introduction of the sweet potato in the 1950's. Having flown 
and walked over much of the basin, I find it impossible to imagine 
where L. s. gajduseki could have maintained itself before garden 
agriculture. The streams traversing the basin are confined to narrow 
gorges. Although I have been in 10 of these gorges, I have yet to meet 
a Lonchura or to see riparian vegetation that seemed to offer promise 
of supporting L. s. gajdusekt. Either this race must have slowly evolved 
in some part of the basin not yet discovered—an unattractive pos- 
sibility because of the circumscribed size of the basin and the large 
areas of grassland necessary for L. spectabilis—or else it must have 
evolved in a very short time, perhaps as little as 15 years. This latter 
possibility cannot be dismissed. The studies of Johnston and Selander 
(1964) on Passer domesticus in North America show that rapid morpho- 
logical changes can occur in populations of species colonizing new 
habitats. ‘The variants of wahgiensis in which the adult has pale buff 
underparts may have served as the starting material. Finally, the

selection pressures at Karimui (due to heavy rainfall throughout the 
year) may have been unusually severe, as seen by the general tendency 
towards dark plumage expressed most strikingly in the melanistic 
population of Accipiter novaehollandiae.
