BIRDS OF LA PLATA 

GLITTERING HUMMING-BIRD 

Chlorostilbon splendidus 

Head^ upper parts, and wing-covcrts golden bronze, inclining to 
green on upper tail-coverts ; wings purplish brown ; tail black 
glossed with green ; throat and breast glittering emerald-green ; beak 
bright red ; length 3.5 inches. Female bronze-green above and grey 
beneath. 

THE Trochilidae, or Humming-birds, a distinctly 
South American form, are one of the most 
numerous families of birds on the globe, 
numbering over 400 known species, and ranging over 
the entire continent down to Tierra del Fuego. How 
surprising then to find that of this multitude of species 
no more than about a dozen are found in the entire 
Argentine country 1 It only adds to the surprise when 
it is found that humming-birds of these few species 
are common enough throughout the country. Even 
on the almost treeless grassy pampas of Buenos Ayres 
which are unsuited to the habits of this feathered 
forest sprite, one species at all events is found every- 
where. Personally I was acquainted with only 
three species, and I recall that when living on the 
open pampas, every season when the white acacia 
at my home was in flower we had an invasion of 
Humming-birds. The plantation was divided by 



2 BIRDS OF LA PLATA 

avenues of large acacia trees^ about a thousand 
in all, and as long as the blossoms lasted the little 
glittering birds were to be seen all over the place, 
in almost every tree, revelling in the fragrant sweet- 
ness ; but no sooner were the flowers faded than 
they were gone, and thereafter two or three pairs 
only remained to breed and spend the summer months 
in the plantation. All these birds were of one species 
— the Glittering Humming-bird, but on going a few 
miles from home to the marsh and forest on the low 
shores of the Plata river I would find the other two 
species. I spent a summer, bird- watching, in a 
herdsman's hut in the marshy forest and used to go 
out at sunset to a small open space overgrown with 
viper's-bugloss in flower. There is no flower the 
Humming-bird likes so well, and he is most busy 
feeding just before dark. Here, standing among the 
flowers, I would watch the shining little birds coming 
and going, each bird spending a minute or two 
sucking honey, then vanishing back into the shadowy 
trees, and from fifty to a hundred of them would 
always be in sight all around me at a time. Here 
all three species were feeding together ; but I was 
familiar with the habits of only one, the bird I 
describe here. 

The Glittering Humming-bird appears in the 
vicinity of Buenos Ayres in September, and later 
in the spring is found everywhere on the pampas 
where there are plantations, but it is never seen on 
the treeless plains. Its sudden appearance in con- 



GLITTERING HUMMING-BIRD 3 

siderable numbers in plantations on the pampas, 
where there are flowers to which it is partial, like 
those of the acacia tree, and its just as sudden de- 
parture when the flowers have fallen, have led me 
to conclude that its migration extends much further 
south, probably into mid-Patagonia. Like most 
Humming-birds it is an exquisitely beautiful little 
creature, in its glittering green mantle ; and in its 
aerial life and swift motions a miracle of energy. 
To those who have seen the Humming-bird in a 
state of nature all descriptions of its appearance 
and movements must seem idle. In the life-habits 
of the Trochilidce there is a singular monotony ; 
and the Glittering Humming-bird differs little in 
its customs from other species that have been de- 
scribed. It is extremely pugnacious ; the males meet 
to fight in the air, and rapidly ascend, revolving 
round each other, until when at a considerable 
height they suddenly separate and dart off in opposite 
directions. Occasionally two or three are seen 
flashing by, pursuing each other, with such velocity 
that even the Swift's flight, which is said to cover 
four hundred miles an hour, seems slow in com- 
parison. This species also possesses the habit of 
darting towards a person and hovering bee-like for 
some time close to his face. It also flies frequently 
into a house, at window or door, but does not, like 
birds of other kinds, become confused on such 
occasions, and is much too lively to allow its retreat 
to be cut off. It feeds a great deal on minute spiders, 
and is fond of exploring the surfaces of mud and

brick walls, where it is seen deftly inserting its 
slender crimson bill into the small spider-holes in 
search of prey. The nest, like that of most humming- 
birds, is a small, beautifully-made structure, com- 
posed of a variety of materials held closely together 
with spiders* webs, and is placed on a branch, or 
in a fork, or else suspended from slender drooping 
vines or twigs. Sometimes the nest is suspended to 
the thatch overhanging the eaves of a cottage, for 
except where persecuted the bird is quite fearless of 
man's presence. The eggs are two, and white. 

Besides the little creaking chirp uttered at short 
intervals while flying or hovering, this species has a 
set song, composed of five or six tenuous and squeak- 
ing notes, uttered in rapid succession when the bird 
is perched. It is a song like that of the European 
Goldcrest in shape, and resembles it in sound, but 
is less musical, or more squeaky. 



NACUNDA GOATSUCKER 

Podager nacunda 

Above brown with black vermiculations and blotches ; wings 
black with a broad white bar across the base of the primaries ; four 
outer tail-feathers broadly tipped with white ; breast brown variegated 
with black ; chin fulvous ; band across throat and belly white ; 
length II, wing 9.5 inches. Female similar but without white 
on tail. 

The Specific name of this Goatsucker is from the 
Guarani word Nacunda, which Azara tells us is the 
Indian nickname for any person with a very large 



NACUNDA GOATSUCKER 5 

mouth* In the Argentine country it has several 
names, being called Dormilon (Sleepy-head) or 
Duerme-duerme (Sleep-sleep), also Gallina ciega (Blind 
Hen). It is a large, handsome bird, and differs from 
its congeners in being gregarious, and in never 
perching on trees or entering woods. It is an in- 
habitant of the open pampas. In Buenos Ayres, and 
also in Paraguay, according to A2;ara, it is a summer 
visitor, arriving at the end of September and leaving 
at the end of February. In the love season the male 
is sometimes heard uttering a song or call, with notes 
of a hollow mysterious character; at other times 
they are absolutely silent, except when disturbed in 
the daytime, and then each bird when taking flight 
emits the syllable kuf in a hollow voice. When 
flushed the bird rushes away with a wild zigzag 
flight, close to the ground, then suddenly drops Hke 
a stone, disappearing at the same time from sight 
as effectively as if the earth had swallowed it up, so 
perfect is the protective resemblance in the colouring 
of the upper plumage to the ground. In the evening 
they begin to fly about earlier than most Caprimulgi, 
hawking after insects like swallows, skimming over 
the surface of the ground and water with a swift 
irregular flight ; possibly the habit of sitting in open 
places exposed to the full glare of the sun has made 
them somewhat less nocturnal than other species 
that seek the shelter of thick woods or herbage 
during the hours of light. 

The Nacunda breeds in October, and makes no 
nest, but lays two eggs on a scraped place on the 



6 BIRDS OF ^ PLATA 

open plain, Mr. Dalgleish says of the eggs : 
'* They are oval-shaped, and resemble much in 
appearance those of the Nightjar, except that the 
markings, which are similar in character to those 
of the latter, are of a reddish-brown or port-wine 
colour/' 

After the breeding-season they are sometimes 
found in flocks of forty or fifty individuals, and will 
spend months on the same spot, returning to it in 
equal numbers every year. One summer a flock of 
about two hundred individuals frequented a meadow 
near my house, and one day I observed them rise up 
very early in the evening and begin soaring about 
like a troop of swallows preparing to migrate. I 
watched them for upwards of an hour ; but they 
did not scatter as on previous evenings to seek for 
food, and after a while they began to rise higher and 
higher, still keeping close together, until they dis- 
appeared from sight. Next morning I found that 
they had gone. 

In Entrerios, Mr. Barrows tells us, this Goat- 
sucker is an abundant summer resident, arriving early 
in September and departing again in April. It is 
strictly crepuscular or nocturnal, never voluntarily 
taking wing by daylight. In November it lays a pair 
of spotted eggs in a hollow scooped in the soil of 
the open plain. These in shape and markings re- 
semble eggs of the Night-hawk {Chordeiles virginianus), 
somewhat, but are of course much larger, and have 
a distinct reddish tinge. ** We found the birds not 
uncommon near Bahia Blanca, 17th February, 1881, 



RED-CRESTED WOODPECKER 7 

but elsewhere on the Pampas we did not observe 
them/' 

There are altogether close on fifty species of 
Goatsuckers in South America ; of these^ six are 
found in Argentina, I only knew two ; the one here 
described and the small species Antrostomus parvulus, 
which is rare in Buenos Ayres, 



RED-CRESTED WOODPECKER 

Chrysoptilus cristatus 

Above black barred with white ; rump white with black spots ; 
top of head blacky nape scarlet ; sides of head white^ bordered with 
black ; beneath white, yellowish on the neck, covered with round 
black spots ; throat white striped with black ; tail black, lateral 
rectrices slightly barred with yellow; length 10.5 inches. Female 
similar. 

South and Central America has not fewer than 130 
species of Woodpeckers ; in Argentina there are 
only thirteen species known, and most of these are 
confined to the northern and forest districts. Five 
species range as far south as Buenos Ayres ; of these 
I was acquainted with the following four. 

The Red-crested Woodpecker ranges as far south 
as the vicinity of Buenos Ayres, and is not uncommon 
there in the few localities which possess wild forests. 
It is the handsomest of our Woodpeckers, having 
brighter tints than its congener of the plains, Colaptes 



8 BIRDS OF LA PLATA 

agricola. Like that bird, though not to the same 
extent, it has diverged from the typical Picidse 
in its habits, ahghting sometimes on the ground 
to feed, and also frequently perching crosswise on 
branches of trees. It has a powerful, clear, abrupt, 
and oft-repeated note, and a rapid undulating 
flight. 

The following interesting account of its breeding 
habits appears in a paper by Mr. Gibson : '' The ex- 
cavation for the nest is begun as early as September ; 
but the eggs are only laid during the first half of 
October. The hole is generally commenced where 
some branch has decayed away ; but care is taken 
that the remainder of the tree is sound. It opens 
at a height of from six to nine feet from the ground, 
and is excavated to a depth of nearly a foot. Occasion- 
ally it is sufficiently wide to admit of one*s hand, but 
such is not always the case. No preparation is made 
for the eggs beyond the usual lining of some chips 
of wood. 

** The pair which frequented the garden excavated 
a hole in a paradise-tree, and bred there for two 
consecutive years. The tree stood near one of the 
walks, and on any one passing the sitting bird imme- 
diately showed its head at the aperture, like a jack- 
in-the-box, and then flew away. Last year this pair 
actually bred in one of the posts of the horse-corral, 
notwithstanding the noise and bustle incident to such 
a locahty. While waiting there, at sunrise, for the 
herd of horses to be shut in I used often to knock at 
the post, in order to make the Woodpecker leave its 



RED-CRESTED WOODPECKER 9 

nest, but the bird seemed indifferent to such a mild 
attack, and would even sit still while a hundred 
horses and mares rushed about the corral or hurled 
themselves against the sides of it. In another case I 
had worked with hammer and chisel for half-an-hour, 
cutting a hole on a level with the bottom of a nest, 
when the female first demonstrated her presence by 
flying out almost into my face. This last nest con- 
tained four (considerably incubated) eggs, which I 
took. Happening to pass the spot a fortnight after, 
I inspected the hole and was surprised to find that it 
had been deepened and another five eggs laid, while 
the entrance I had cut was the one now used by the 
birds. The nest was again resorted to the following 
year and a brood hatched out, but since then a pair 
of Wrens have occupied the place to the exclusion 
of the rightful owners,*' 

The eggs are white, four or five in number, pear- 
shaped, and with polished shells. 

White obtained specimens of this Woodpecker in 
Catamarca, and Mr, Barrows found it resident in 
Entrerios, The latter tells us it is ** abundant in the 
woods everywhere, and conspicuous for its activity, 
bright colours, and large size/' 



lo BIRDS OF LA PLATA 



PAMPAS WOODPECKER 

Colaptes agricola 

Above greyish white, transversely barred with black ; wings black 
with golden-yellow shafts, and white bars on the outer webs ; rump 
white with small black cross-bars ; crested head black ; sides of head 
and neck in front yellow ; malar stripe red ; length 13 inches. 
Female similar, but without the red malar stripe. 

The species commonly called Carpintero in the 
Argentine country, and ranging south to Patagonia, 
is one of a group of the Picidee of South America 
which diverge considerably in habits from the typical 
Woodpeckers. On trees they usually perch horizon- 
tally and crosswise, like ordinary birds, and only 
occasionally cling vertically to trunks of trees, using 
the tail as a support. They also seek their food 
more on the ground than on trees, in some cases 
not at all on trees, and they also breed oftener in 
holes in banks or cliffs than in the trunks of trees* 
As Darwin remarks in The Origin of SpecieSy in his 
chapter on Instinct^ these birds have, to some slight 
extent, been modified structurally in accordance with 
their less arboreal habits, the beak being weaker, the 
rectrices less stiff, and the legs longer than in other 
Woodpeckers. In South Brazil and Bolivia the 
Colaptes campestris represents this group, in Chili 
C. pitius, and in the Argentine country C. agricola. 

Azara's description, under the heading El Cam- 
pestre, probably refers to the Brazilian species, but 
agrees so well in every particular with the Pampas 




Pampas Woodpecker 

Colaptes agricola, Malh. 



PAMPAS WOODPECKER ii 

Woodpecker that I cannot do better than quote it 
in full* 

** Though this name (Campestre) seems inappro- 
priate for any Woodpecker, no other better describes 
the present species, since it never enters forests, nor 
climbs on trunks to seek for insects under the bark, 
but finds its aliment on the open plain, running with 
ease on the ground, for its legs are longer than in 
the others. There it forcibly strikes its beak into the 
matted turf, where worms or insects lie concealed, 
and when the ant-hills are moist it breaks into them 
to feed on the ants or their larvae* It also perches on 
trees, large or small, on the trunks or branches, 
whether horisjontal or upright, sometimes in a cling- 
ing position, and sometimes crosswise in the manner 
common to birds. Its voice is powerful, and its cry 
uttered frequently both when flying and perching. 
It goes with its mate or family, and is the most 
common species in all these countries. It lays two 
to four eggs, with white, highly polished shells, 
and breeds in holes which it excavates in old walls 
of mud or of unbaked brick, also in the banks of 
streams ; and the eggs are laid on the bare floor 
without any lining.^' 

In Patagonia, where I have found this bird breeding 
in the cliffs of the Rio Negro, its habits are precisely 
as A2;ara says ; but on the pampas of Buenos Ayres, 
where the conditions are different, there being no 
cliffs or old mud-walls suitable for breeding-places, 
the bird resorts to the big solitary ombti tree (Pircunia 
dioica), which has a very soft wood, and excavates 



12 BIRDS OF LA PLATA 

a hole seven to nine inches deep^ inclining upwards 
near the end^ and terminating in a round chamber. 

This reversal to an ancestral habit^ which (con- 
sidering the modified structure of the bird) must 
have been lost at a very remote period in its history, 
is exceedingly curious. Formerly this Woodpecker 
was quite common on the pampas. I remember that 
when I was a small boy quite a colony lived in the 
ombii trees growing about my home ; now it is 
nearly extinct, and one may spend years on the 
plains without meeting with a single example. 

Mr. Barrows speaks as follows of this species : 
** Abundant and breeding at all points visited. At 
Concepcion, where it is resident, it is by far the 
commonest Woodpecker. The ordinary note very 
much resembles the reiterated alarm-note of the 
Greater Yellow-legs (Totanus melanoleucus)^ but so 
loud as to be almost painful when close at hand, and 
easily heard a mile or more away. They spend much 
time on the ground, and I often found the bills of 
those shot quite muddy. A nest found near Concep- 
cion, 6th November, 1880, was in the hollow trunk 
of a tree, the entrance being through an enlarged 
crack at a height of some three feet from the ground. 
The five white eggs were laid on the rubbish at the 
bottom of the cavity, perhaps a foot above the ground. 
In the treeless region about the Sierra de la Ventana 
we saw this bird about holes on the banks of the 
streams, where it doubtless had nests.'' 



RINGED KINGFISHER 13 



RINGED KINGFISHER 

Ceryle torquata 

Above greyish blue with narrow black shaft-stripes and small round 
white spots ; wings black with a portion of the inner webs towards 
the base white, tail black barred with white ; beneath chestnut-red ; 
throat and belly white; length 15 inches. Female similar but with 
broad blue pectoral band. 

This beautiful bird, the largest of the American 
Kingfishers, is found throughout the greater portion 
of South and Central America. In Argentina it is 
not common but is widely distributed and is known 
both in Buenos Ayres and Patagonia. In southern 
Patagonia it varies in colour and is of a slatey grey- 
blue on the upper parts, thickly sprinkled like a 
guinea-fowl with minute round white spots, hence 
the specific name stellatat bestowed on it by some 
ornithologists who regard it as a separate species. 

Notwithstanding its wide distribution and great 
beauty, little has been recorded of the habits of this 
species. In Amazonia, Bartlett says, *' it breeds in 
company with Ceryle amazona. The nest, however, 
is placed very much deeper in the bank than in the 
case of the last-named bird, the hole being from four 
to six feet in depth, with a chamber at the end 
sufficiently large for the young birds when nearly 
full-grown.*^ 

Two other species of Kingfishers range as far 
south as the Buenos Ayres pampas. The first, a 
third less in size than the Ringed Kingfisher, is the 



14 BIRDS OF LA PLATA 

Amazonian Kingfisher^ Ceryle [amazonaf its colour 
above dark green, beneath white with a broad chest- 
nut pectoral band. In Buenos Ayres this bird was 
fairly common and was usually seen in pairs. Its 
cry is exceedingly loud, hard, and abrupt, and so 
rapidly reiterated as to give it a sound resembling 
that of a policeman*s rattle. But this is not its only 
language, and I was greatly surprised one day at 
hearing one warbling long clear notes, somewhat 
flute-like in quality, as it flew from tree to tree along 
the borders of a stream. It seems very strange that 
there should be a melodious Kingfisher ; but Mr. 
Barrows also heard the allied Ceryle americana sing, 
much to his surprise. My belief is that the birds of 
this group possess a singing faculty but very rarely 
exercise it ; with C. americana I am well acquainted, 
yet I never heard it utter any note except its hard 
rattling cry, resembling that of C. amazona, but less 
powerful. 

This Kingfisher was found by White at Cosquin, 
where it is usually met with along the acequias, or 
canals made for the purpose of irrigating the culti- 
vated lands. These canals are in places bordered 
with brushwood and trees, and are tolerably deep, 
with a swiftly flowing current, and abound in small 
fishes, so that this bird seems to prefer them as 
hunting-grounds to the rocky river-bed. 

In Entrerios Mr. Barrows tells us this Kingfisher 
is not uncommon along the Lower Uruguay, and 
sometimes ascends the smaller streams a short distance. 
It is much more easily approached than C. torquata* 



GUIRA CUCKOO 15 

The other species, the smallest of its family in 
South America, the Little Kingfisher, Ceryle ameri- 
canaf is about the size of the European Kingfisher, 
and resembles the last one described in its colouring. 
In its habits and language it also resembles the 
C. amazona. 

It should be noted that the Kingfishers are poorly 
represented in South America, there being but eight 
species known in the entire continent, and these all 
of the one genus Ceryle. In the Old World there 
are 120 species known, and many genera. 



GUIRA CUCKOO 

Guira piririgua 

Above dark brown with white shaft-stripes ; head brown ; wings 
reddish brown ; rump white ; tail white, crossed by a broad black 
band, the two central feathers uniform brown ; beneath dull white ; 
throat and breast with long linear black shaft-stripes ; bill and feet 
yellow ; length 15 inches. Female similar. 

Piririgua, the specific term adopted by naturalists 
for this bird, is, according to A^ara, the verna- 
cular name of the species in Paraguay. He says in 
that country it is abundant, but scarce in the Plata 
district. No doubt it has greatly increased and 
extended its range southwards during the hundred 
years which have elapsed since his time, as it is now 
very common in Buenos Ayres, where its vernacular 
name is Urraca (Magpie). In the last-named country 



i6 BIRDS OF LA PLATA 

it is not yet quite in harmony with its environment. 
Everywhere its habit is to feed exclusively on the 
ground^ in spite of possessing feet formed for climb- 
ing ; but its very scanty plumage, slow laborious 
flight, and long square tail, so unsuitable in cold 
boisterous weather, show that the species is a still 
unmodified intruder from the region of perpetual 
summer many degrees nearer to the equator. 

The Guira Cuckoo is about sixteen inches long, 
has red eyes and blue feet, and an orange-red beak. 
The crown of the head is deep rufous, and the loose 
hair-like feathers are lengthened into a pointed crest. 
The back and rump are white, the wings and other 
upper parts very deep fuscous, marked with white 
and pale brown. Under surface dull white, with 
hair-like black marks on the throat and breast. The 
tail is square, nine to ten inches long ; the two middle 
feathers dark brown, the others three-coloured — 
yellow at the base, the middle portion dark glossy 
green, the ends white ; and when the bird is flying 
the tail, spread out like a fan, forms a conspicuous 
and beautiful object. 

During the inclement winter of Buenos Ayres the 
Guira Cuckoo is a miserable bird, and appears to 
suffer more than any other creature from cold. In 
the evening the flock, usually composed of from a 
dozen to twenty individuals, gathers on the thick 
horizontal branch of a tree sheltered from the wind, 
the birds crowding close together for warmth, and 
some of them roosting perched on the backs of their 
fellows. I have frequently seen them roosting three 



GUIRA CUCKOO 17 

deep, one or two birds at the top to crown the pyra- 
mid ; but with all their huddling together a severe 
frost is sure to prove fatal to one or more birds in 
the flock ; and sometimes several birds that have 
dropped from the branch stiff with cold are found 
under the trees in the morning. If the morning is 
fair the flock betakes itself to some large tree, on 
which the sun shines, to settle on the outermost 
twigs on the northern side, each bird with its wings 
drooping, and its back turned towards the sun. In 
this spiritless attitude they spend an hour or two 
warming their blood and drying the dew from their 
scanty dress. During the day they bask much in 
the sun, and towards evening may be again seen on 
the sunny side of a hedge or tree warming their backs 
in the last rays. It is owing, no doubt, to its fecun- 
dity and to an abundance of food that the Guira 
Cuckoo is able to maintain its existence so far south 
in spite of its terrible enemy the cold. 

With the return of warm weather this species 
becomes active, noisy, and the gayest of birds ; the 
flock constantly wanders about from place to place, 
the birds flying in a scattered desultory manner one 
behind the other, and incessantly uttering while on 
the wing a long complaining cry. At intervals during 
the day they also utter a kind of song, composed of a 
series of long modulated whistling notes, two- 
syllabled, the first powerful and vehement, and 
becoming at each repetition lower and shorter, then 
ending in a succession of hoarse internal sounds like 
the stertorous breathing of a sleeping man. When 



i8 BIRDS OF LA PLATA 

approached all the birds break out into a chorus of 
alarm, with rattling notes so annoyingly loud and 
sustained that the intruder, be it man or beast, is 
generally glad to hurry out of ear-shot. As the 
breeding-season approaches they are heard, probably 
the males, to utter a variety of soft low chattering 
notes, sounding sometimes like a person laughing 
and crying together : the flock then breaks up into 
pairs, the birds becoming silent and very circum- 
spect in their movements. The nest is usually built 
in a thorn-tree, of rather large sticks, a rough large 
structure, the inside often lined with green leaves 
plucked from the trees. The eggs are large for the 
bird, and usually six or seven in number ; but the 
number varies greatly, and I have known one bird 
lay as many as fourteen. They are elliptical in form 
and beautiful beyond comparison, being of an ex- 
quisite turquoise-blue, the whole shell roughly 
spattered with white. The white spots are composed 
of a soft calcareouo substance, apparently deposited 
on the surface of the shell after its complete forma- 
tion : they are raised, and look like snow-flakes, and 
when the egg is fresh-laid may be easily washed off 
with cold water, and are so extremely delicate that 
their purity is lost on the egg being taken into the 
hand. The young birds hatched from these lovely 
eggs are proverbial for their ugliness, Pichon de 
Urraca being a term of contempt commonly applied 
to a person remarkable for want of comeliness. They 
are as unclean as they are ugly, so that the nest, 
usually containing six or seven young, is unpleasant 



GUIRA CUCKOO 19 

both to sight and smell. There is something 
ludicrous in the notes of these young birds, resem- 
bling as they do the shrill half-hysterical laughter 
of a female exhausted by over-indulgence in mirth. 
One summer there was a large brood in a tree close 
to my home, and every time we heard the parent 
bird hastening to her nest with food in her beak, 
and uttering her plaintive cries, we used to run to 
the door to hear them. As soon as the old bird 
reached the nest they would burst forth into such 
wild extravagant peals and continue them so long 
that we could not but think it a rare amusement to 
listen to them. 

According to A^^ara the Guira Cuckoo in Paraguay 
has very friendly relations with the Ani (Crotophaga 
ani)f the birds consorting together in one flock, and 
even laying their eggs in one nest ; and he affirms 
that he has seen nests containing eggs of both species. 
These nests were probably brought to him by his 
Indian collectors, who were in the habit of deceiving 
him, and it is more than probable that in this matter 
they were practising on his credulity ; though it is 
certain that birds of different species do sometimes 
lay in one nest, as I have found — the Common Teal 
and the Tinamu for instance. I also doubt very 
much that the bird is ever polygamous, as A^ara 
suspected ; but it frequently wastes eggs, and its 
procreant habits are sometimes very irregular and 
confusing, as the following case will show : 

A flock numbering about sixteen individuals 
passed the winter in the trees about my home, and 



ao BIRDS O^LA PLATA 

in spring scattered about the plantation, screaming 
and chattering in their usual manner when about 
to breed. I watched them, and found that after a 
time the flock broke up into small parties of three 
or four, and not into couples, and I could not detect 
them building. At length I discovered three broken 
eggs on the ground, and on examining the tree 
overhead found an incipient nest composed of about 
a dozen sticks laid crossways and out of which the 
eggs had been dropped. This was in October, and 
for a long time no other attempt at a nest was made ; 
but wasted eggs were dropped in abundance on the 
ground, and I continued finding them for about 
four months. Early in January another incipient 
nest was found, and on the ground beneath it six 
broken eggs. At the end of that month two large 
nests were made, each nest by one pair of birds, and 
in the two fourteen or fifteen young birds were 
reared. 

When taken young the Guira Cuckoos become 
very tame, and make bold, noisy, mischievous pets, 
fond of climbing over and tugging at the clothes, 
buttons, and hair of their master or mistress. They 
appear to be more intelligent than most birds, and 
in a domestic state resemble the Magpie. I knew 
one tame Cuckoo that would carry off and jealously 
conceal bits of bright-coloured ribbon, thread, or 
cloth. In a wild state their food consists largely of 
insects, which they sometimes pursue running and 
flying along the ground. They also prey on mice 
and small reptiles, and carry off the fledglings from 



BLACK-BILLED CUCKOO 31 

the nests of Sparrows and other small birds, and in 
spring they are frequently seen following the plough 
to pick up worms ♦ 



BLACK-BILLED CUCKOO 

Coccyzus melanocoryphus 

Above pale greyish brown ; head cinereous, a black stripe through 
the eyes ; beneath white, tinged with ochreous ; tail black, tipped 
with white, the two central feathers like the back ; length 1 1 .5 
inches. Female similar. 

The CoucoUt so called from its note, is the 
commonest species of the genus in the Argentine 
Republic, and has an extensive range in South 
America. In September it migrates south, and a pair 
or a few individuals re-appear faithfully every spring 
in every orchard or plantation on the pampas. At 
intervals its voice is heard amidst the green trees — 
deep, hoarse, and somewhat human-like in sound, 
the song or call being composed of a series of notes, 
like the syllables cou-cou-coUf beginning loud and 
full, and becoming more rapid until at the end they 
run together. It is a shy bird, conceals itself from 
prying eyes in the thickest foliage, moves with ease 
and grace amongst the closest twigs, and feeds 
principally on large insects and caterpillars, for 
which it searches amongst the weeds and bushes 
near the ground. 

The nest is the flimsiest structure imaginable, 
being composed of a few dry twigs, evidently broken 



33 BIRDS O^LA PLATA 

by the bird from the trees and not picked up from 
the ground. They are laid across each other to make 
a platform nest, but so small and flat is it that the 
eggs frequently fall out from it. That a bird should 
make no better preparation than this for the great 
business of propagation seems very wonderful. The 
eggs are three or four in number, elliptical in form, 
and of a dull sea-green colour. 

There are three more species in Argentina of the 
characteristic American genus Coccyzus ; one of 
these which I discovered to be an Argentine species 
being the common Yellow-billed Cuckoo of North 
America, Coccyzus americanus. I met with it in 
plantations on the pampas, but always in the late 
summer or autumn months — February to April — 
and am therefore unable to say whether or not it 
breeds in that district. It may be that this Cuckoo, 
like some of the Sandpipers and other shore birds of 
North America, extends its annual migration south 
to the pampas and Patagonia. But it is hardly believ- 
able that any Cuckoo could make that journey. If 
not, one must suppose that this Cuckoo, like the 
Purple Martin, has two races, which may have their 
meeting-ground in the tropics; at all events both 
winter in the tropics, and to breed one flies north in 
May, the other south in September. 

Another interesting species is the Cinereous 
Cuckoo, Coccyzus cinereus, of a nearly uniform 
ashy grey colour with black bill. This Cuckoo is 
smaller than the preceding species, and also differs 
in having a square tail and a more curved beak. The 



BLACK-BILLED CUCKOO 23 

beak is black, and the irides blood-red, which 
contrasts well with the blue-grey of the head, giving 
the bird a bold and striking appearance. 

This species is not common, but it is, I believe, 
slowly extending its range southwards, as within the 
last few years it has become much more common 
than formerly. Like other Cuckoos, it is retiring in 
its habits, concealing itself in the dense foliage, and 
it cannot be attracted by an imitation of its call, an 
expedient which never fails with the Coucou, Its 
language has not that deep mysterious or monkish 
quality, as it has been aptly called, of other CoccyzL 
Its usual song or call, which it repeats at short 
intervals all day long during the love-season, re- 
sembles the song of our little Dove {Columhula picui)y 
and is composed of several long monotonous notes, 
loud, rather musical, but not at all plaintive. It 
also has a loud harsh cry, which one finds it hard 
to believe to be the voice of a Cuckoo, as in character 
it is more like the scream of a Dendrocolaptine species. 

Of the thirty species of Cuckoos inhabiting South 
America eight are found in Argentina, Four of the 
five species described above were known to me ; the 
remaining three did not range so far south as Buenos 
Ayres — '' my parish of Selborne," as I have ventured 
to call it in the Naturalist in La Plata — but they are 
such interesting birds that I cannot resist the tempta- 
tion of giving a brief account of their habits in this 
place. 

The Ani, Crotophaga ani^ is about the si2;e of our 
Magpie, and is one of the strangest of this strange 



24 BIRDS OF LA PLATA 

family, with the plumage and some of the habits of 
a crow, being almost entirely of a uniform black, 
glossed with bronze, dark green, and purple* Its 
most peculiar feature is the beak, which is greater 
in depth than in length, and resembles an immense 
Roman nose, occupying the whole face, and with the 
bridge bulging up above the top of the head. The 
Ani is found only in the northern portion of the 
Argentine territory. According to Azara it is very 
common in Paraguay, and goes in flocks, associating 
with the Guira Cuckoo, which it resembles in its 
manner of flight, in being gregarious, in feeding on 
the ground, and in coming a great deal about houses : 
in all which things these two species differ widely 
from most Cuckoos. He also says that it has a loud 
disagreeable voice, follows the cattle about in the 
pastures like the Cow-bird, and builds a large nest 
of sticks lined with leaves, in which as many as twenty 
or thirty eggs are frequently deposited, several 
females laying together in one nest. His account of 
these strange and disorderly breeding-habits has 
been confirmed by independent observers in other 
parts of the continent. The eggs are oval and out- 
wardly white, being covered with a soft white 
cretaceous deposit ; but this can be easily scraped 
off, and under it is found a smooth hard shell of a 
clear beautiful blue colour. 

The second species is the Brown Cuckoo, Diplop- 
terus naBviuSf called Crispin in the vernacular and 
found throughout the hot portion of South America, 
and in different districts varying considerably in 



BLACK-BILLED CUCKOO 25 

size and colouring. It is about twelve inches long, 
the beak much curved ; the prevaihng colour of the 
upper parts is light brown, the loose feathers on the 
head, which form a crest, deep rufous. The upper 
tail-coverts are long loose feathers of very unequal 
length, the longest reaching nearly to the end of the 
tail. The under surface is dirty white, or dashed 
with grey. 

Azara says it is called Chochi in Paraguay, and has 
a clear, sorrowful note of two syllables, which it 
repeats at short intervals during the day, and also 
at night during the love-season. It is solitary, scarce, 
and excessively shy, escaping at the opposite side of 
the tree when approached, and when seen having 
the head and crest raised in an attitude of alarm. 
In the northern part of the Argentine country it is 
called Crispin^ from its note which clearly pronounces 
that name. Mr. Barrows found it common at Con- 
cepcion on the Uruguay river, and has written the 
following notes about it : 

*' Several were taken in open bushy places, and 
many others were heard. It is a plain but attractive 
Cuckoo with a few-feathered crest, and long soft 
flowing upper tail-coverts. The note is very clear 
and penetrating, sounding much like the word 
' Crispin ' slowly uttered, and with the accent on the 
last syllable. The birds are very shy, and I followed 
one for nearly an hour before I saw it at all, and 
nearly twice that time before any chance of a shot 
was offered. There is some peculiarity in the note 
which makes it impossible to tell whether the bird is 



a6 BIRDS OF LA PLATA 

in front of or behind you — even when the note itself 
is distinctly heard* I know nothing of nest or eggs/* 

From personal observation I can say nothing about 
this species, as I never visited the district where it is 
found ; but with the fame of the Crispin I have 
always been familiar, for concerning this Cuckoo the 
Argentine peasants have a very pretty legend. It is 
told that two children of a woodcutter, who lived in 
a lonely spot on the Uruguay, lost themselves in the 
woods — a little boy named Crispin and his sister. 
They subsisted on wild fruit, wandering from place 
to place, and slept at night on a bed of dry grass and 
leaves. One morning the little girl awoke to discover 
that her brother had disappeared from her side. 
She sprang up and ran through the woods to seek 
for him, but never found him ; but day after day 
continued wandering in the thickets calling ** Cris- 
pin^ Crispin/* until at length she was changed into 
a little bird, which still flies through the woods on 
its never-ending quest, following every stranger who 
enters them, calling after him ** Crispin, Crispin ** 
a by chance it should be her lost brother. 

The last species is the Chestnut Cuckoo, Piaya 
cayana* This is a widely spread form of Cuckoo in 
Central and South America, and reaches the northern 
territories of the Argentine Republic, having been 
obtained by Durnford near Tucuman, and by White 
in Misiones. The whole bird is about eighteen inches 
long, and the tail very long in proportion, about 
eleven inches. The entire plumage, except the breast 
and belly, which are grey, is chestnut colour. The 



PATAGONIAN PARROT a? 

beak is very strong, and yellowish green in colour ; 
the irides ruby-red, the eyelids scarlet. 

In Colombia this Cuckoo is said to be called 
Pdjaro ardilla (Squirrel-bird), from its chestnut tint. 
It seems to feed chiefly, if not altogether, on the 
ground, and when perched always appears awkward 
and ill at ease. On a branch it sits motionless, until 
approached, and then creeps away through the leaves 
and escapes on the opposite side of the tree. This, 
however, is a habit common to most Cuckoos. Its 
language is a loud screaming cry, on account of which 
the Bradlians call it Alma do gatOf implying that it 
possesses the soul of a cat. It is a very shy retiring 
bird, and in this respect is more like a Coccyzus than 
a Guira* 

For these facts we are indebted to Leotaud, Fra^er, 
Forbes, White, and others ; each of these observers 
having contributed a few words to a history of this 
interesting bird's habits. 



PATAGONIAN PARROT 

Conurus patagonus 

Above dark olive-green ; wings edged with bluish ; lower part of 
back yellow ; beneath olive-green, darkest on throat ; whitish band 
across the neck ; belly yellow, with patch in the middle and thighs 
dark crimson ; length i8, wing 9.2, tail 10.5 inches. Female similar. 

This Parrot, called in La Plata the Bank- or Bur- 
rowing-Parrot, from its nesting-habits, is the only 
member of its order found so far south as Patagonia. 



28 BIRDS OF LA PLATA 

In habits it differs somewhat from most of its con- 
geners^ and it may be regarded, I think, as one of 
those species which are dying out — possibly owing 
to the altered conditions resulting from the settle- 
ment of the country by Europeans* It was formerly 
abundant on the southern pampas of La Plata, and 
being partially migratory its flocks ranged in winter 
to Buenos Ayres, and even as far north as the Parana 
river. When, as a child, I lived near the capital city 
(Buenos Ayres), I remember that I always looked 
forward with the greatest delight to the appearance 
of these noisy dark-green winter visitors. Now they 
are rarely seen within a hundred miles of Buenos 
Ayres ; and I have been informed by old gauchos 
that half a century before my time they invariably 
appeared in immense flocks in winter, and have since 
gradually diminished in numbers, until now in that 
district the Bank-Parrot is almost a thing of the past. 
Two or three hundreds of miles south of Buenos 
Ayres city they are still to be met with in rather 
large flocks, and have a few ancient breeding-places, 
to which they cling very tenaciously. Where there 
are trees or bushes on their feeding-ground they 
perch on them ; they also gather the berries of the 
Empetrum ruhrum and other fruits from the bushes ; 
but they feed principally on the ground, and while 
the flock feeds one bird is invariably perched on a 
stalk or other elevation to act as sentinel. They are 
partial to the seeds of the giant thistle {Carduus 
mariana) and the wild pumpkin, and to get at the 
latter they bite the hard dry shell into pieces with 



PATAGONIAN PARROT ag 

their powerful beaks. When a horseman appears 
in the distance they rise in a compact flock, with loud 
harsh screams, and hover above him, within a very 
few yards of his head, their combined dissonant 
voices producing an uproar which is only equalled 
in that pandemonium of noises, the Parrot-house in 
the Zoological Gardens of London. They are 
extremely social, so much so that their flocks do not 
break up in the breeding-season ; and their burrows, 
which they excavate in a perpendicular cliff or high 
bank, are placed close together ; so that when the 
gauchos take the young birds — esteemed a great 
delicacy — the person who ventures down by means 
of a rope attached to his waist is able to rifle a colony. 
The burrow is three to five feet deep, and four white 
eggs are deposited on a slight nest at the extremity. 
I have only tasted the old birds, and found their 
flesh very bitter, scarcely palatable. 

The natives say that this species cannot be taught 
to speak ; and it is certain that the few individuals 
I have seen tame were unable to articulate. 

Doubtless these Parrots were originally stray 
colonists from the tropics, although now resident 
in so cold a country as Patagonia. When viewed 
closely one would also imagine that they must at 
one time have been brilliant - plumaged birds ; 
but either natural selection or the direct effect of 
a bleak climate has given a sombre shade to their 
colours — green, blue, yellow, and crimson ; and 
when seen flying at a distance, or in cloudy weather, 
they look as dark as crows. 



30 BIRDS OF LA PLATA 

GREEN PARRAKEET 

Bolborhynchus monachus 

Green ; front grey ; wings blackish with slight bluish edgings ; 
beneath grey ; bill whitish ; length 1 1 inches. Female similar. 

The Common Green Parrakeet, called Cotorra or 
Catita in the vernacular, is a well-known resident 
species in the Argentine Republic, It is a lively, 
restless bird, shrill-voiced, and exceedingly voci- 
ferous, living and breeding in large communities, 
and though it cannot learn to speak so distinctly 
as some of the larger Parrots, it is impossible to 
observe its habits without being convinced that it 
shares in the intelligence of the highly-favoured order 
to which it belongs* 

In Buenos Ayres it was formerly very much more 
numerous than it is now ; but it is exceedingly 
tenacious of its breeding-places, and there are some 
few favoured localities where it still exists in large 
colonies, in spite of the cruel persecution all birds 
easily killed are subjected to in a country where 
laws relating to such matters are little regarded, 
and where the agricultural population is chiefly 
Italian. At Mr. Gibson's residence near Cape San 
Antonio, on the Atlantic coast, there is still a large 
colony of these birds inhabiting the Tala woods 
(Celtis tala)f and I take the following facts from one 
of his papers, contributed many years ago to the IbiSf 
on the ornithology of the district. 

He describes the woods as being full of their nests, 



GREEN PARRAKEET 31 

with their bright-coloured talkative deni^ens^ and 
their noisy chatter all day long drowning every other 
sound. They are extremely sociable and breed in 
communities. When a person enters the wood, their 
subdued chatter suddenly ceases, and during the 
ominous silence a hundred pairs of black beady eyes 
survey the intruder from the nests and branches ; 
and then follow a whirring of wings and an outburst 
of screams that spread the alarm throughout the 
woods. The nests are frequented all the year, and 
it is rare to find a large one unattended by some of 
the birds any time during the day. In summer and 
autumn they feed principally on the thistle ; first 
the flower is cut up and pulled to pieces for the sake 
of the green kernel, and later they eat the fallen seed 
on the ground. Their flight is rapid, with quick 
flutters of the wings, which seem never to be raised 
to the level of the body. They pay no regard to a 
Polyhorus or Milvago (the Carrion Eagle and Carrion 
Hawk), but mob any other bird of prey appearing 
in the woods, all the Parrakeets rising in a crowd and 
hovering about it with angry screams. 

The nests are suspended from the extremities of 
the branches, to which they are firmly woven. New 
nests consist of only two chambers, the porch and 
the nest proper, and are inhabited by a single pair 
of birds. Successive nests are added, until some of 
them come to weigh a quarter of a ton, and contain 
material enough to fill a large cart. Thorny twigs, 
firmly interwoven, form the only material, and there 
is no lining in the breeding-chamber, even in the 



32 BIRDS OF LA PLATA 

breeding-season. Some old forest trees have seven 
or eight of these huge structures suspended from the 
branches, while the ground underneath is covered 
with twigs and remains of fallen nests. The entrance 
to the chamber is generally underneath, or if at the 
side is protected by an overhanging eave to prevent 
the intrusion of opossums. These entrances lead 
into the porch or outer chamber, and the latter 
communicates with the breeding-chamber. The 
breeding-chambers are not connected with each 
other, and each set is used by one pair of birds. 

The number of pairs does not exceed a dozen, 
even with the lafgest nests. Repairs are carried on 
all the year round, but new nests are only added at 
the approach of spring. Opossums are frequently 
found in one of the higher chambers, when the 
entrance has been made too high, but though they 
take up their abode there they cannot reach the 
other chambers, and the Parrakeets refuse to go away, 
A species of Teal (probably Querquedula hrasiliensis) 
also sometimes occupies and breeds in their cham- 
bers, and in one case Mr. Gibson found an opossum 
domiciled in an upper chamber, Parrakeets occupying 
all the others except one, in which a Teal was sitting 
on eggs. 

The breeding-season begins about ist November, 
and as many as seven or eight eggs are laid ; these 
are dull white, very thin-shelled, elongated, and have 
the greatest diameter exactly equidistant from the 
two ends. 

Mr. Barrows speaks as follows of this species in 



SHORT-EARED OWL 33 

Entrerios : *' An abundant and familiar bird in 
the neighbourhood of Concepcion through the entire 
year. It is commonly seen in flocks of twenty and 
upwards, visiting grain-fields, gardens, etc., and 
sometimes, if I was correctly informed, completely 
stripping the grain-fields. They nest in communities, 
many pairs uniting in the building of a large common 
nest or mass of nests. I only saw these nests on two 
occasions, and had no opportunity of examining 
their structure. They were placed on high trees, 
and appeared from below to be simply irregular 
masses, six or eight feet in diameter, formed of 
small sticks and twigs. Where the nests are abun- 
dant the natives destroy the young by hundreds, 
and the ' squabs ' when nearly grown are said to 
be very fine eating. The young are easily tamed, 
and may be taught to articulate a few simple words.''

There are but six Owls known in Argentina, a very 
small number in so vast a country when we remem- 
ber that England alone has five species without

counting the occasional visitants. It is also sur- 
prising to find that two of the Argentine owls are 
well-known British species — the Barn Owl and the 
wide-ranging Short-eared OwL Of the six species 
I was acquainted with five, and will describe the 
two I knew most intimately, the Short-eared and 
the Burrowing Owls» The White or Barn Owl I 
occasionally saw in Buenos Ayres city, but always at 
night : the noble Magellanic Eagle Owl and the 
small Pigmy Owl I met with on the Rio Negro in 
Patagonia, 

The Short-eared Owl is found throughout the 
Argentine country, where it is commonly called 
Lechuzon (Big Owl) in the vernacular. Like the 
Barn-Owl it has an exceedingly wide range. It is 
found throughout the continent of Europe ; it also 
inhabits Asia and Africa, many of the Pacific Islands, 
and both Americas, from Canada down to the Straits 
of Magellan. Such a very wide distribution would 
seem to indicate that it possesses some advantage 
over its congeners, and is (as an Owl) more perfect 
than others. It is rather more diurnal in its habits 
than most Owls, and differs structurally from other 
members of its order in having a much smaller head. 
It is also usually said to be a weak flier ; but this 
I am sure is a great mistake, for it seems to me to be 
the strongest flier amongst Owls, and very migratory 
in its habits, or, at any rate, very much given to 
wandering. Probably its very extensive distribution 
is due in some measure to a greater adaptability than 



SHORT-EARED OWL 35 

is possessed by most species ; also to its better 
sight in the daytime, and to its wandering dis- 
position, which enables it to escape a threatened 
famine, and to sei^e on unoccupied or favourable 
ground. 

The bird loves an open country, and sits by day 
on the ground concealed amongst the herbage or 
tall grass. An hour before sunset it quits its hiding- 
place and is seen perched on a bush or tall stalk, or 
sailing about a few feet above the ground with a 
singularly slow, heron-like flight ; and at intervals 
while flying it smites its wings together under its 
breast in a quick, sudden manner* It is not at all shy, 
the intrusion of a man or dog in the field it frequents 
only having the effect of exciting its indignation. 
An imitation of its cry will attract all the individuals 
within hearing about a person, and any loud unusual 
sound, like the report of a gun, produces the same 
effect. When alarmed or angry it utters a loud hiss, 
and at times a shrill laugh-like cry. It also has a 
dismal scream, not often heard ; and at twilight 
hoots, this part of its vocal performance sounding 
not unlike the distant baying of a mastiff or a blood- 
hound. It breeds on the ground, clearing a circular 
spot, and sometimes, but not often, lining it with 
a scanty bed of dry grass. The eggs are three to five, 
white, and nearly spherical. 

The Short-eared Owl was formerly common 
everywhere on the pampas, where the coarse indi- 
genous grasses afforded the shelter and conditions 
best suited to it. When in time this old rough 



36 BIRDS OF LA PLATA 

vegetation gave place to t^soft perishable grasses 
and clovers, accidentally introduced by European 
settlers, the Owl disappeared from the country, like 
the large Tinamu {Rhynchotis rufescens)^ the Red- 
billed Finch (Embernagra platensis)^ and various 
other species ; for the smooth level plains afforded 
it no shelter. Now, however, with the spread of 
cultivation, it has reappeared, and is once more 
becoming a common bird in the more settled 
districts. 



BURROWING-OWL 

Speotyto cunicularia 

Above dark sandy brown, with large white oval spots and small 
spots and freckles of pale brown ; wings with broad whitish cross- 
bars ; facial disk greyish brown ; beneath white ; length lo, wing 7.5, 
tail 3.5 inches. Female similar, but larger. 

The Burrowing-Owl is abundant everywhere on the 
pampas of Buenos Ayres and avoids woods, but not 
districts abounding in scattered trees and bushes. 
It sees much better than most Owls by day, and 
never affects concealment nor appears confused by 
diurnal sounds and the glare of noon. It stares 
fixedly — ** with insolence," A^ara says — ^at a passer- 
by, following him with the eyes, the round head 
turning about as on a pivot. If closely approached 
it drops its body or bobs in a curious fashion, emit- 
ting a brief scream, followed by three abrupt ejacula-

BURROVVING-OWl, 
Speotyto ciiiiicularia (MdI.) 



BURROWING-OWL 37 

tions ; and if made to fly goes only fifteen or twenty 
yards away, and alights again with face towards the 
intruder ; and no sooner does it alight than it repeats 
the odd gesture and scream, standing stiff and erect, 
and appearing beyond measure astonished at the 
intrusion* By day it flies near the surface with wings 
continuously flapping, and invariably before alighting 
glides upwards for some distance and comes down 
very abruptly* It frequently runs rapidly on the 
ground, and is incapable of sustaining flight long* 
Gaucho boys pursue these birds for sport on horse- 
back, taking them after a chase of fifteen or twenty 
minutes* As a boy I have myself taken many* They 
live in pairs all the year, and sit by day at the mouth 
of their burrow or on the Vi^cacha's mound, the 
two birds so close together as to be almost touching ; 
when alarmed they both fly away, but sometimes 
the male only, the female diving into the burrow* 
On the pampas it may be more from necessity than 
choice that they always sit on the ground, as they 
are usually seen perched on the summits of bushes 
where such abound, as in Patagonia* 

These are the commonest traits of the Burrowing- 
Owl in the settled districts, where it is excessively 
numerous and has become familiar with man ; but 
in the regions hunted over by the Indians it is a 
scarce bird and has different habits* Shy of approach 
as a persecuted game-fowl, it rises to a considerable 
height in the air when the approaching traveller is 
yet far off, and flies often beyond sight before descend- 
ing again to the earth* This wildness of disposition 



38 BIRDS OF LA PLATA 

is, without doubt, due to xne active animosity of 
the pampas tribes, who have all the ancient wide- 
spread superstitions regarding the Owl. ^* Sister of 
the Evil Spirit " is one of their names for it ; they 
hunt it to death whenever they can, and when travel- 
ling will not stop to rest or encamp on a spot where 
an Owl has been spied. Where the country is settled 
by Europeans the bird has dropped its wary habits 
and become extremely tame. They are tenacious 
of the spot they live in, and are not easily driven out 
by cultivation. When the fields are ploughed up 
they make their kennels on their borders, or at the 
roadsides, and sit all day perched on the posts of 
the fences. 

Occasionally they are seen preying by day, especi- 
ally when anything passes near them, offering the 
chance of an easy capture. I have often amused 
myself by throwing bits of hard clay near one as it 
sat beside its kennel ; for the bird will immediately 
give chase, only discovering its mistake when the 
object is firmly clutched in its talons. When there 
are young to be fed, they are almost as active by day 
as by night. On hot November days multitudes of 
a large species of Scarabeeus appear, and the bulky 
bodies and noisy bungling flight of these beetles 
invite the Owls to pursuit, and on every side they 
are seen pursuing and striking down the beetles, 
and tumbling upon them in the grass. Owls have a 
peculiar manner of taking their prey ; they grapple 
it so tightly in their talons that they totter and 
strive to steady themselves by throwing out their 



BURROWING-OWL 39 

wings, and sometimes, losing their balance, fall 
prostrate and flutter on the ground. If the animal 
captured be small they proceed after a while to 
despatch it with the beak ; if large they usually rise 
laboriously from the ground and fly to some distance 
with it, thus giving time for the wounds inflicted 
by the claws to do their work. 

At sunset the Owls begin to hoot ; a short followed 
by a long note is repeated many times with an interval 
of a second of silence. There is nothing dreary or 
solemn in this performance ; the voice is rather 
soft and sorrowful, somewhat resembling the lowest 
notes of the flute in sound. In spring they hoot a 
great deal, many individuals responding to each 
other. 

In the evening they are often seen hovering like a 
Kestrel at a height of forty feet above the surface, and 
continuing to do so fully a minute or longer without 
altering their position. They do not drop the whole 
distance at once on their prey, but descend vertically, 
tumbling and fluttering as if wounded, to within ten 
yards of the earth, and then, after hovering a few 
seconds more, glide obliquely on to it. They prey on 
every living creature not too large to be overcome by 
them. Sometimes when a mouse is caught they tear 
off the head, tail, and feet, devouring only the body. 
The hind quarters of toads and frogs are almost in- 
variably rejected ; and inasmuch as these are the 
most fleshy and succulent parts, this is a strange 
and unaccountable habit. They make an easy con- 
quest of a snake eighteen inches long, and kill it by 



40 BIRDS OF LA PLATA 

dealing it blows with the be^ hopping briskly about 
it all the time, apparently to guard themselves with 
their wings. They prey largely on the common 
Coronella anomala, but I have never seen one at- 
tacking a venomous species. When they have young 
many individuals become destructive to poultry, 
coming about the houses and carrying off the chickens 
and ducklings by day. In seasons of plenty they 
destroy far more prey than they can devour ; but 
in severe winters they come, apparently starving, 
about the houses, and will then stoop to carry off 
any dead animal food, though old and dried up 
as a piece of parchment. This I have often seen 
them do. 

Though the Owls are always on familiar terms 
with the Vizcachas (Lagostomus trichodactylus) and 
occasionally breed in one of their disused burrows, 
as a rule they excavate a breeding-place for them- 
selves. The kennel they make is crooked, and varies 
in length from four to twelve feet. The nest is placed 
at the extremity, and is composed of wool or dry 
grass, often exclusively of dry horse-dung. The 
eggs are usually five in number, white, and nearly 
spherical ; the number, however, varies, and I have 
frequently found six or seven eggs in a nest. After 
the female has begun laying the birds continue 
carrying in dry horse-dung, until the floor of the 
burrow and a space before it is thickly carpeted with 
this material. The following spring the loose earth 
and rubbish is cleared out, for the same hole may 
serve them two or three years. It is always untidy. 



BURROWING-OWL 41 

but mostly so during the breeding-season, when 
prey is very abundant, the floor and ground about 
the entrance being often httered with castings, green 
beetle-shells, pellets of hair and bones, feathers of 
birds, hind quarters of frogs in all stages of decay, 
great hairy spiders (Mygale), remains of half-eaten 
snakes, and other unpleasant creatures that they 
subsist on. But all this carrion about the little Owl's 
disordered house reminds one forcibly of the im- 
portant part the bird plays in the economy of nature. 
The young birds ascend to the entrance of the burrow 
to bask in the sun and receive the food their parents 
bring; when approached they become irritated, 
snapping with their beaks, and retreat reluctantly 
into the hole ; and for some weeks after leaving it 
they make it a refuge from danger. Old and young 
birds sometimes live together for four or five months. 
I believe that nine-tenths of the Owls on the pampas 
make their own burrows, but as they occasionally 
take possession of the forsaken holes of mammals to 
breed in, it is probable that they would always 
observe this last habit if suitable holes abounded, 
as on the North American prairies inhabited by the 
marmot. Probably our Burrowing-Owl originally 
acquired the habit of breeding in the ground in the 
open level regions it frequented; and when this 
habit (favourable as it must have been in such un- 
sheltered situations) had become ineradicable, a want 
of suitable burrows would lead it to clean out such 
old ones as had become choked up with rubbish, 
to deepen such as were too shallow, and ultimately 



42 BIRDS OF LA PLATA 

to excavate for itself. Tiff mining instinct varies 
greatly in strength, even on the pampas. Some pairs, 
long mated, only begin to dig when the breeding 
season is already on them ; others make their bur- 
rows as early as April — that is, six months before 
the breeding-season. Generally both birds work, 
one standing by and regarding operations with an 
aspect of grave interest, and taking its place in 
the pit when the other retires ; but sometimes the 
female has no assistance from her partner, and the 
burrow then is very short. Some pairs work expedi- 
tiously and their kennel is deep and neatly made ; 
others go about their task in a perfunctory manner, 
and begin, only to abandon, perhaps half a dozen 
burrows, and then rest two or three weeks from 
their unprofitable labours. But whether industrious 
or indolent, by September they all have their burrows 
made. I can only account for Azara*s unfortunate 
statement, repeated by scores of compilers, that the 
Owl never constructs its own habitations, by assum- 
ing that a century ago, when he lived and when the 
country was still very sparsely settled, this Owl had 
not yet become so abundant or laid aside the wary 
habit the aborigines had taught it, so that he did 
not become very familiar with its habits. 



ARGENTINE HEN-HARRIER 43 



ARGENTINE HEN-HARRIER 

Circus cinereus 

Above light bluish grey with darker mottlings ; primaries blackish ; 
tail grey with four black cross bands and tipped with white ; beneath 
thickly banded with white and rufous bars ; bill blacky eyes and feet 
yellow; length i8^ wing 12 inches. Female larger; above dark 
brown^ with light brown spots. 

There are two species of Harriers in Argentina, the 
Broad-winged Harrier, C» macropterus, with a black 
upper and white lower plumage, and the present 
species, named Cinereous Harrier in Argentine Orni- 
thology ^ but I prefer now to call it the Argentine 
Hen-Harrier, as at a distance it closely resembles 
the European Hen-Harrier, although a handsomer 
bird. 

This hawk is found throughout the Argentine 
Republic, and is also common in Patagonia and the 
Falkland Islands ♦ On the pampas it is, I think, the 
most common bird of prey, after the excessively 
abundant Milvago chimango. Like the Chimango 
it also prefers an open unwooded country, and 
resembles that bird not a little in its general appear- 
ance, and when in the brown stage of plumage may 
be easily mistaken for it. In the Falklands it has 
even acquired the Carrion Hawk's habits, for Darwin 
distinctly saw one feeding on a carcase there, very 
much to his surprise. On the pampas I have always 
found it a diligent bird-hunter, and its usual mode 
of proceeding is to drive up the bird from the grass 



44 BIRDS OF LA PLATA 

and to pursue and striked down with its claws, 
Mr. Gibson's account of its habits agrees with mine, 
and he says that '' it will raise any small bird time 
after time, should the latter endeavour to conceal 
itself in the grass, preferring, as it would seem, to 
strike it on the wing/' He further says : ''Its 
flight is low and rather rapid, while if its quarry 
should double it loses no ground, for it turns some- 
thing in the manner of a Tumbler Pigeon, going 
rapidly head over heels in the most eccentric and 
amusing fashion/' 

Probably this Harrier has a partial migration, as 
a great many are always seen travelling across the 
pampas in the autumn and spring ; many individuals, 
however, remain all the winter. 

The nest is made on the ground among long grass, 
or in reed-beds in marshy places, and the eggs are 
white, blotched with dark red. 



VOCIFEROUS HAWK 

Asturina pucherani 

Above dark brown ; upper tail-coverts fulvous^ barred with brown ; 
wings chestnut barred and broadly tipped with black ; tail fulvous, 
crossed with four black bars ; beneath pale ochraceous, barred with 
rufous ; bill black, feet yellow; length i8 inches. Female larger. 

This brown-plumaged, short-winged, and exceed- 
ingly vociferous Hawk is common in the woods 
along the shores of the Plata and its tributaries, and 
is never found far removed from water. It perches 



WHITE-TAILED BUZZARD 45 

on the summit of a tree^ and sits there motionless 
for hours at a time, and at intervals utters singularly 
long, loud cries, which become more frequent and 
piercing when the bird is disturbed, as by the ap- 
proach of a person. Its flight is rapid and irregular, 
the short blunt wings beating unceasingly, while 
the bird pours out a succession of loud, vehement, 
broken screams. 

Mr. Barrows observed it on the Lower Uruguay, 
and writes : "It feeds largely if not exclusively on 
fish, nearly every specimen having their remains 
(and nothing else) in their stomachs.'* It would be 
very interesting to learn how it captures its prey. 



WHITE-TAILED BUZZARD 

Buteo albicaudatus 

Above greyish black, scapulars and upper wing coverts ferruginous ; 
rump and tail white, the latter with a broad black band ; throat 
black, beneath white; bill black, feet yellow; length 31, wing 18 
inches. Female similar but larger. 

This Bu^^ard does not breed on the pampas, where 
I have observed it, but appears there in the spring 
and autumn, irregularly, when migrating, and in 
flocks which travel in a loitering, desultory manner. 
The flocks usually number from thirty or forty to 
a hundred birds, but sometimes many more. I have 
seen flocks which must have numbered from one to 



46 BIRDS OF LA PLATA 

two thousand birds. When flying the flock is very 
much scattered^ and does not advance in a straight 
line, but the birds move in wide circles at a great 
height in the air, so that a person on horseback 
travelling at a canter can keep directly under them 
for two or three hours. On the ground one of these 
large flocks will sometimes occupy an area of half a 
square league, so widely apart do the birds keep. I 
have dissected a great many and found nothing but 
coleopterous insects in their stomachs ; and indeed 
they would not be able to keep in such large com- 
panies when travelling if they required a nobler 
prey. 

At the end of one summer a flock numbering 
about two hundred birds appeared at an estancia 
near my home, and though very much disturbed 
they remained for about three months, roosting at 
night on the plantation trees, and passing the day 
scattered about the adjacent plain, feeding on grass- 
hoppers and beetles. This flock left when the weather 
turned cold ; but at another estancia a flock appeared 
later in the season and remained all the winter. The 
birds became so reduced in flesh that after every 
cold rain or severe frost numbers were found dead 
under the trees where they roosted ; and in that 
way most of them perished before the return of 
spring. 




Red-Backed Buzzard 

Beteo erythronotHS (King) 



RED-BACKED BUZZARD 47 



RED-BACKED BUZZARD 

Buteo erythronotus 

Above slatey blue ; wing feathers slatey with narrow black bars ; 
upper tail-coverts and tail white^ the latter crossed with narrow 
grey bars and broad black band ; beneath white ; bill dark horn- 
colour ; feet yellow ; length 25, wing 18.5 inches. Female similar, 
but back deep chestnut. 

This is a fine bird — the king of South-American 
Buzzards* In the adult female the three colours of 
the plumage are strongly contrasted ; the back being 
rusty rufous, the rest of the upper parts grey, the 
whole under surface pure white. It is occasionally 
met with in the northern provinces of the Argentine 
Republic, but is most common in Patagonia ; and 
it has been said that in that region it takes the place 
of the nearly allied Buteo albicaudatus of Brazil. In 
habits, however, the two species are as different as 
it is possible for two Raptores to be; for while the 
northern bird has a cowardly spirit, is, to some 
extent, gregarious, and feeds largely on insects, the 
Patagonian species has the preying habits of the 
Eagle and lives exclusively, I believe, or nearly so, 
on cavies and other small mammals. When Captain 
King first discovered it in 1827, ^^ described it as 
*' a small beautiful Eagle.^' In Patagonia it is very 
abundant, and usually seen perched on the summit 
of a bush, its broad snowy-white bosom conspicuous 
to the eye at a great distance — one of the most 
familiar features in the monotonous landscape of 



48 BIRDS OF LA PLATA 

that grey country. The English colonists on the 
Chupat^ Durnford says, call it the ** White Horse/' 
owing to its conspicuous white colour often deceiving 
them when they are out searching for strayed horses 
in the hills. It is a wary bird, and when approached 
has the habit of rising up in widening circles to a 
vast height in the air. When sailing about in quest 
of prey it usually maintains a height of fifty or sixty 
yards above the surface. The stomachs of all the 
individuals I have examined contained nothing but 
the remains of cavies {Cavia australis)* 

The nest is built on the top of a thorn bush, and is 
a large structure of sticks, lined with grass, fur, dry 
dung, and other materials. The eggs are greyish 
white in colour, blotched and marked, principally 
towards the large end, with two shades of umber- 
brown. 



GREY EAGLE 

Geranoaetus melanoleuciu 

Above black, wings grey with narrow transverse black bars ; tail 
black ; throat grey ; breast black with round whitish spots ; abdomen 
white ; bill horn-colour, feet yellow ; length 26, wing 19 inches. 

The Grey or Chilian Eagle, like most diurnal birds of 
prey, undergoes many changes of colour, the plumage 
at different periods having its brown, black, and grey 
stages : in the old birds it is a uniform clear grey, 
and the under surface white. Throughout the 



GREY EAGLE 49 

Argentine country this is the commonest Eagle, and 
I found it very abundant in Patagonia* D'Orbigny 
describes it with his usual prolixity — pardonably so 
in this case, however, the bird being one of the very 
few species with which he appears to have become 
familiar from personal observation. He says that it 
is a wary bird ; pairs for life, the male and female 
never being found far apart ; and that it soars in 
circles with a flight resembling that of a Vulture ; 
and that the form of its broad blunt wings increases 
its resemblance to that bird. Cavies and small 
mammals are its usual prey ; and in the autumn 
and winter, when the Pigeons congregate in large 
numbers, it follows their movements. During the 
Pigeon-season he has counted as many as thirty 
Eagles in the course of a three leagues^ ride ; and he 
has frequently seen an Eagle swoop down into a cloud 
of Pigeons, and invariably reappear with one strug- 
gling in its talons. It is seldom found far from the 
shores of the sea or of some large river ; and on the 
Atlantic coast, in Patagonia, it soars above the sands 
at ebb-tide, looking out for stranded fish, carcases 
of seals, and other animal food left by the retiring 
waters, and quarrels with Condors and Vultures over 
the refuse, even when it is quite putrid. It acts as 
a weather prognostic, and before a storm is seen to 
rise in circles to a vast height in the air, uttering 
piercing screams, which may be heard after it has 
quite disappeared from sight. 

The nest of this species is usually built on the 
ledge of an inaccessible rock or precipice, but not 



50 BIRDS OF LA PLATA 

infrequently on a tree. Mr. Gibson describes one, 
which he found on the top of a thorn-tree, as a 
structure of large sticks, three feet in diameter, the 
hollow cushioned with dry grass. It contained two 
eggs, dull white, marked with pale reddish blotches. 

Mr. Gibson compared its cry to a '* wild human 
laugh,*' and also writes : ^* Its whereabouts may often 
be detected by an attendant flock of Caranchos 
{Polyhorus tharus), particularly in the case of a young 
bird. As soon as it rises from the ground or from a 
tree, these begin to persecute it, ascending spirally 
also, and making dashes at it, while the Eagle only 
turns its head watchfully from side to side, the 
mere action being sufficient to avert the threatened 
collision.** 

Gay, in his Natural History of Chili, describes the 
affectionate and amusing habits of an Eagle of this 
species which he had tamed. It took great delight in 
playing with his hand, and would sei^e and pretend 
to bite one of his fingers, but really with as much 
tenderness as a playful dog displays when pretending 
to bite its master. It used also to amuse itself by 
picking up a pebble in its beak, and with a jerk of 
its head toss it up in the air, then sei2;e it in its 
claws when it fell, after which it would repeat the 
performance. 



CROWNED EAGLE 51 



CROWNED EAGLE 

Harpyhaliaetus coronatus 

Above ashy brown, with a long crest of darker feathers ; wings 
grey with blackish tips ; tail black with a broad white median band 
and white tip ; beneath pale ashy brown ; length 33, wing 22 inches. 
Female similar but larger. 

I MET with this fine Eagle on the Rio Negro^ in 
Patagonia, where d'Orbigny also found it; the 
entire Argentine territory comes, however, within 
its range. Having merely seen it perched on the tall 
willows fringing the Rio Negro, or soaring in wide 
circles far up in the sky, I cannot venture to speak 
of its habits, while the account of them which 
d'Orbigny built up is not worth quoting, for he does 
not say how he got his information. One of his 
statements would, if true, be very important indeed. 
He says that his attention was drawn to a very curious 
fact concerning the Crowned Harpy, which was, that 
this bird preys chiefly on the skunk — an animal, he 
very truly adds, with so pestilential an odour that 
even the most carnivorous of mammals are put to 
flight by it ; that it is the only bird of prey that 
kills the skunk, and that it does so by precipitating 
itself from a vast height upon its quarry, which it 
then quickly despatches. It would not matter at 
all whether the Eagle dropped from a great or a 
moderate height, for in either case the skunk would 
receive its enemy with the usual pestilent discharge. 
D'Orbigny's account is, however, pure conjecture, 



52 BIRDS OF LA PLATA 

and though he does not tell us what led him to form 
such a conclusion; I have no doubt that it was because 
the Eagle or Eagles he obtained had the skunk-smell 
on their plumage* Most of the Eagles I shot in Pata- 
gonia, including about a do^en Chilian Eagles, smelt 
of skunk, the smell being in most cases old and faint. 
Of two Crowned Harpies obtained, only one smelt 
of skunk. This only shows that in Patagonia Eagles 
attack the skunk, which is not strange considering 
that it is of a suitable size and conspicuously marked ; 
that it goes about fearlessly in the daytime and is the 
most abundant animal, the small cavy excepted, in 
that sterile country. But whether the Eagles succeed 
in their attacks on it is a very different matter. The 
probability is that when an Eagle, incited by the 
pangs of hunger, commits so great a mistake as to 
attack a skunk, the pestilent fluid, which has the 
same terribly burning and nauseating effects on the 
lower animals as on man, very quickly makes it 
abandon the contest. It is certain that pumas make 
the same mistake as the Eagles do, for in some that 
are caught the fur smells strongly of skunk. It might 
be said that the fact that many Eagles smell of skunk 
serves to show that they do feed on them, for other- 
wise they would learn by experience to avoid so dan- 
gerous an animal, and the smell of a first encounter 
would soon wear off. I do not think that hungry 
birds of prey, in a barren country like Patagonia, 
would learn from one repulse, or even from several, 
the fruitlessness and danger of such attacks ; while 
the smell is so marvellously persistent that one or 



PEREGRINE FALCON 53 

two such attacks a year on the part of each Eagle 
would be enough to account for the smell on so 
many birds* If skunks could be easily conquered 
by Eagles^ they would not be so numerous or so 
neglectful of their safety as we find them. 



PEREGRINE FALCON 

Falco peregrinus 

Above plumbeous, lightest on the rump, more or less distinctly 
barred with black ; head and cheeks black ; beneath white tinged with 
cinnamon ; abdomen and thighs traversed by narrow black bands ; 
cere and feet yellow; length 30^ wing 14 inches. Female similar; 
a third larger. 

The Peregrine Falcon is found throughout the 
Argentine Republic, but is nowhere numerous, and 
is not migratory ; nor is it ** essentially a duck- 
hawk/^ as in India according to Dr. Anderson, for 
it preys chiefly on land birds. It is solitary, and 
each bird possesses a favourite resting-place or home^ 
where it spends several hours every day, and also 
roosts at night. Where there are trees it has its 
chosen site where it may always be found at noon ; 
but on the open treeless pampas a mound of earth 
or the bleached skull of a horse or cow serves it for 
a perch, and here for months the bird may be found 
every day on its stand. It sits upright and motionless, 
springs suddenly into the air when taking flight, and 
flies in a straight line, and with a velocity which few 
birds can equal. Its appearance always causes great 



54 BIRDS OF LA PLATA 

consternation amongst other birds, for even the Spur- 
winged Lapwing, the spirited persecutor of all other 
Hawks, flies screaming with terror from it. It prefers 
attacking moderately large birds, striking them on 
the wing, after which it stoops to pick them up. 
While out riding one day I saw a Peregrine sweep 
down from a great height and strike a Burrowing- 
Owl to the earth, the Owl having risen up before 
me. It then picked it up and flew away with it in 
its talons. 

The Peregrine possesses one very curious habit. 
When a Plover, Pigeon, or Duck is killed, it eats the 
skin and flesh of the head and neck, picking the 
vertebrae clean of the flesh down to the breast-bone, 
and also eating the eyes, but leaving the body 
untouched, I have found scores of dead birds with 
head and neck picked clean in this way ; and once 
I watched for some months a Peregrine which had 
established itself near my home, where it made 
havoc among the Pigeons ; and I frequently marked 
the spot to which it carried its prey, and on going 
to the place always found that the Pigeon's head and 
neck only had been stripped of flesh. The Burrow- 
ing Owl has an analogous habit, for it invariably 
rejects the hind quarters of the toads and frogs which 
it captures. 

At the approach of the warm season the Peregrines 
are often seen in twos and threes violently pursuing 
each other at a great height in the air, and uttering 
shrill, piercing screams, which can be heard distinctly 
after the birds have disappeared from sight. 



ARGENTINE HOBBY 55 

ARGENTINE HOBBY 

Falco fusco-cserulescens 

Above dull slatey black, rump variegated with white ; superciliaries 
prolonged and meeting behind, rufous ; beneath throat and breast 
pale cinnamon with black shaft-stripes on the breast ; belly black 
with white transverse hnes ; wings and tail blackish with transverse 
white bars ; bill yellow tipped with black, feet orange ; length 13.5, 
wing 10 inches. Female similar but larger. 

The Orange-chested Hobby is found throughout 
South and Central America^ but the form met with 
here differs^ to some extent, in habits from its repre- 
sentatives of the hotter region. It is a Patagonian 
bird, the most common Falcon in that country, and 
is migratory, wintering in the southern and central 
Argentine provinces* In its winter home it is solitary, 
and fond of hovering about farmhouses, where it 
sits on a tree or post and looks out for its prey* Com- 
pared with the Peregrine it has a poor spirit, and 
I have often watched it give chase to a bird, and 
just when it seemed about to grasp its prey, give up 
the pursuit and slink ingloriously away. It never 
boldly and openly attacks any bird, except of the 
smallest species, and prefers to perch on an elevation 
from which it can dart down suddenly and take its 
prey by surprise. 

The nest is a slovenly structure of sticks on a 
thorny bush or tree. The eggs, which I have not 
seen, Darwin describes as follows : ** Surface rough 
with white projecting points ; colour nearly uni- 
form dirty wood-brown ; general appearance as if 
it had been rubbed in brown mud/* 



56 BIRDS OF LA PLATA 



ARGENTINE KESTREL 

Tinnunculus cinnamominus 

Above reddish cinnamon with irregular black cross bands on the 
back ; head bluish grey ; front and sides of head white ; nape and 
stripes on the sides of the neck black ; wings bluish grey with black 
central spots ; tail cinnamon red with broad black band and white 
tip ; beneath white with buff tinge, and irregular oval black spots ; 
length 10.5, wing 7.7 inches. Female similar but larger. 

The habits of this little Falcon closely resemble 
those of Falco fusco-cxrulescens, and like that bird 
it is common in Patagonia and migrates north in 
winter. Many individuals, however, do not migrate, 
as I found when residing at the Rio Negro, where 
some pairs remained at the breeding-place all the 
year. Many pairs are also found resident and breeding 
in other parts of the Argentine country, but it is 
common only in Patagonia, 

It nests in holes in cliffs and also on trees, and 
sometimes builds its own nest on the large nest of 
a Dendrocolaptine bird or of a Parrakeet. It lays 
four eggs, large for the size of the bird, oval in shape, 
and white, thickly blotched with dull red. 

The preying habits of the Little Kestrel are similar 
to those of the Orange-chested Hobby ; it haunts 
farmhouses and plantations, and spends a great 
deal of time perched on some elevation watching 
for its prey, and making sudden dashes to capture 
it by surprise. But though not bold when seeking 
its food, it frequently makes violent unprovoked 
attacks on species very much larger than itself, either 



WHITE KITE 57 

from ill-temper or in a frolicsome spirit, which is 
more probable. 

Thus I have seen one drive up a flock of Glossy 
Ibises and pursue them some distance, striking and 
buffeting them with the greatest energy. I saw 
another pounce down from its perch, where it had 
been sitting for some time, on a female skunk quietly 
seated at the entrance of her burrow, with her three 
half-grown young frolicking around her. I was 
watching them with extreme interest, for they were 
leaping over their parent's tail, and playing like 
kittens with it, when the Hawk dashed down, and 
after striking at them quickly three or four times, 
as they tumbled pell-mell into their kennel, flew 
quietly away, apparently well satisfied with its 
achievement. 



WHITE KITE 

Elanus leucurus 

Above pale grey ; lesser wing-coverts and scapulars black ; tail 
white, the two middle feathers grey ; beneath white ; bill black, eyes 
crimson; feet yellow; length 14.5, wing 11, tail 7 inches. Female 
similar but larger. 

This interesting Hawk is found throughout the 
Argentine Republic, but is nowhere numerous. It 
also inhabits Chili, where. Gay says, it is called 
Bailarin (Dancer) on account of its aerial perform- 
ances. It is a handsome bird, with large ruby-red 
irides, and when seen at a distance its snow-white 



58 BIRDS OF LA PLATA 

plumage and buoyant flight give it a striking re- 
semblance to a gulL Its wing-power is indeed 
marvellous. It delights to soar, like the Martins, 
during a high wind, and will spend hours in this 
sport, rising and falling alternately, and at times, 
seeming to abandon itself to the fury of the gale, 
is blown away like thistle-down, until, suddenly 
recovering itself, it shoots back to its original position. 
Where there are tall Lombardy poplar-trees these 
birds amuse themselves by perching on the topmost 
slender twigs, balancing themselves with outspread 
wings, each bird on a separate tree, until the tree-tops 
are swept by the wind from under them, when they 
often remain poised almost motionless in the air 
until the twigs return to their feet. 

When looking out for prey, this Kite usually main- 
tains a height of sixty or seventy feet above the 
ground, and in its actions strikingly resembles a 
fishing Tern, frequently remaining poised in the air 
with body motionless and wings rapidly vibrating 
for fully half a minute at a stretch, after which it 
flies on or dashes down upon its prey. 

The nest is placed upon the topmost twigs of a 
tall tree, and is round and neatly built of sticks, 
rather deep, and lined with dry grass. The eggs are 
eight in number, nearly spherical, the ground-colour 
creamy-white, densely marked with longitudinal 
blotches or stripes of a fine rich red, almost like 
coagulated blood in hue. There is, however, great 
variety in the shades of red, also in the disposition 
of the markings, these in some eggs being confluent. 



SOCIABLE MARSH-HAWK 59 

so that the whole shell is red* The shell is polished 
and exceedingly fragile^ a rare thing in the eggs of a 
Raptor* 

An approach to the nest is always greeted by the 
birds with long distressful cries^ and this cry is also 
uttered in the love-season, when the males often 
fight and pursue each other in the air* The old and 
young birds usually live together until the follow- 
ing spring* 



SOCIABLE MARSH-HAWK 

Rostrohamus sociabilis 

Deep slatey grey ; wing feathers black ; rump white ; tail white 
with a broad grey band ; eyes crimson, bill and feet orange ; length 
17, wing 13 inches. Female similar but larger. 

This Hawk in si^e and manner of flight resembles 
a Buzzard, but in its habits and the form of its slender 
and very sharply hooked beak it differs widely from 
that bird. The name of Sociable Marsh-Hawk, 
which Azara gave to this species, is very appropriate, 
for they invariably live in flocks of from twenty to 
a hundred individuals, and migrate and even breed 
in company* In Buenos Ayres they appear in Sep- 
tember and resort to marshes and streams abounding 
in large water-snails {AmpuUaria)f on which they 
feed exclusively* Each bird has a favourite perch 
or spot of ground to which it carries every snail it 
captures, and after skilfully extracting the animal 
with its curiously modified beak, it drops the shell 



6o BIRDS OF LA PLATA 

on the mound. When disturbed or persecuted by 
other birds, they utter a pecuHar cry, resembHng 
the shrill neighing of a horse. In disposition they 
are most peaceable, and where they are abundant 
all other birds soon discover that they are not as 
other Hawks are and pay no attention to them. 
When soaring, which is their favourite pastime, the 
flight is singularly slow, the bird frequently remain- 
ing motionless for long intervals in one place ; but 
the expanded tail is all the time twisted about in the 
most singular manner, moved from side to side, and 
turned up until its edge is nearly at a right angle 
with the plane of the body. These tail-movements 
appear to enable it to remain stationary in the air 
without the rapid vibratory wing-motions practised 
by Elanus leucurus and other hovering birds ; and 
I should think that the vertebrae of the tail must 
have been somewhat modified by such a habit. 

Concerning its breeding habits Mr, Gibson writes : 
** In the year 1873 I was so fortunate as to find a 
breeding colony in one of our largest and deepest 
swamps. There were probably twenty or thirty 
nests, placed a few yards apart, in the deepest and 
most lonely part of the whole * canadon,' They were 
slightly built platforms, supported on the rushes and 
two or three feet above the water, with the cup- 
shaped hollow lined with pieces of grass and water- 
rush. The eggs never exceeded three in a nest ; the 
ground-colour generally bluish-white, blotched and 
clouded very irregularly with dull red-brown, the 
rufous tint sometimes being replaced with ash-grey.*' 



PIGMY FALCON 6i 

PIGMY FALCON 

Spiziapteryx circumcinctus 

Above brown with black shaft-stripes; head black with brown 
stripes and white superciliaries which join round the nape ; rump 
white ; wings black with white oval spots on the outer and white 
bars on the inner webs; tail black, all but the central feathers 
crossed by five or six broad white bars ; beneath white, the breast 
marked with narrow black shaft-stripes ; beak plumbeous, lower 
mandible yellow; feet greenish ; length ii, wing 6.5 inches. Female 
similar, rather larger. 

This small Hawk is sometimes met with in the 
woods of La Plata^ near the river ; it is rare, but 
owing to its curious violent flight, with the short 
blunt wings rapidly beating all the time, it is very 
conspicuous in the air and well known to the natives, 
who call it Rey de los Pdjaros (King of the Birds) 
and entertain a very high opinion of its energy and 
strength* I have never seen it taking its prey, and 
do not believe that it ever attempts to capture any- 
thing in the air, its short, blunt wings and peculiar 
manner of flight being unsuited for such a purpose. 
Probably it captures birds by a sudden dash when 
they mob it on its perch ; and I do not know any 
Raptor more persistently run after and mobbed by 
small birds. I once watched one for upwards of an 
hour as it sat on a tree attended by a large flock of 
Guira Cuckoos, all excitedly screaming and bent on 
dislodging it from its position* So long as they kept 
away five or six feet from it the Hawk remained 
motionless, only hissing and snapping occasionally 
as a warning ; but whenever a Cuckoo ventured a 



62 BIRDS OF LA PLATA 

little nearer and into the charmed circle^ it would 
make a sudden rapid dash and buffet the intruder 
violently back to a proper distance, returning after- 
wards to its own stand. 



CHIMANGO, OR COMMON CARRION 
HAWK 

Milvago chimango 

Upper plumage reddish brown ; greater wing-coverts white with 
slight brown cross-bars ; tail greyish white, banded and freckled with 
greyish brown. Under plumage grey, tinged with rufous on throat 
and breast; length 15, wing 11, tail 6.5 inches. Sexes alike. 

AzARA says of the Carancho {Polyborus tharus) : 
** All methods of subsistence are known to this 
bird : it pries into, understands, and takes advantage 
of everything/^ These words apply better to the 
Chimango, which has probably the largest bill of 
fare of any bird, and has grafted on to its own 
peculiar manner of life the habits of twenty diverse 
species. By turns it is a Falcon, a Vulture, an insect- 
eater, and a vegetable-eater. On the same day you 
will see one bird in violent Hawk-like pursuit of its 
living prey, with all the instincts of rapine hot within 
it, and another less ambitious individual engaged in 
laboriously tearing at an old cast-off shoe, uttering 
mournful notes the while, but probably more con- 
cerned at the tenacity of the material than at its 
indigestibility. 

A species so cosmopolitan in its tastes might have 



COMMON CARRION HAWK 63 

had a whole volume to itself in England ; being only 
a poor foreigner it has had no more than a few 
unfriendly paragraphs bestowed upon it* For it 
happens to be a member of that South-American 
sub-family of which even grave naturalists have 
spoken slightingly^ calling them vile^ cowardly, con- 
temptible birds ; and the Chimango is nearly least 
of them all — a. sort of poor relation and hanger-on 
of a family already looked upon as bankrupt and 
disreputable. Despite this evil reputation, few 
species are more deserving of careful study ; for 
throughout an extensive portion of South America 
it is the commonest bird we know ; and when we 
consider how closely connected are the lives of all 
living creatures by means of their interlacing rela- 
tions, so that the predominance of any one kind, 
however innocuous, necessarily causes the modifi- 
cation, or extinction even, of surrounding species, 
we are better able to appreciate the importance of 
this despised fowl in the natural polity. Add to 
this its protean habits, and then, however poor a 
creature our bird may seem, and deserving of 
strange-sounding epithets from an ethical point of 
view, I do not know where the naturalist will find 
a more interesting one. 

The Chimango has not an engaging appearance. 
In si^e and figure it much resembles the Hen-Harrier, 
and the plumage is uniformly of a light sandy brown 
colour ; the shanks are slender, claws weak, and 
beak so slightly hooked that it seems like the merest 
apology of the Falcon's tearing weapon. It has an 



64 BIRDS OF LA PLATA 

easy, loitering flight, and when on the wing does not 
appear to have an object in view, like the Hawk, 
but wanders and prowls about here and there, and 
when it spies another bird it flies after him to see 
if he has food in his eye. When one finds something 
to eat the others try to deprive him of it, pursuing 
him with great determination all over the place ; if 
the foremost pursuer flags, a fresh bird takes its 
place, until the object of so much contention — 
perhaps after all only a bit of bone or skin — is 
dropped to the ground, to be instantly snatched up 
by some bird in the tail of the chase ; and he in 
turn becomes the pursued of all the others. This 
continues until one grows tired and leaves off watch- 
ing them without seeing the result. They are 
loquacious and sociable, frequently congregating in 
loose companies of thirty or forty individuals, when 
they spend several hours every day in spirited 
exercises, soaring about like Martins, performing 
endless evolutions, and joining in aerial mock battles. 
When tired of these pastimes they all settle down 
again, to remain for an hour or so perched on the 
topmost boughs of trees or on other elevations ; 
and at intervals one bird utters a very long, leisurely 
chant, with a falling inflection, followed by a series 
of short notes, all the other birds joining in chorus 
and uttering short notes in time with those of their 
soloist or precentor. The nest is built on trees or 
rushes in swamps, or on the ground amongst grass 
and thistles. The eggs are three or four in number, 
nearly spherical, blotched with deep red on a white 



COMMON CARRION HAWK 65 

or creamy ground ; sometimes the whole egg is 
marbled with red ; but there are endless varieties* 
It is easy to find the nest, and becomes easier when 
there are young birds, for the parent when out 
foraging invariably returns to her young uttering 
long mournful notes, so that one has only to listen 
and mark the spot where it alights. After visiting 
a nest I have always found the young birds soon 
disappear, and as the old birds vanish also I believe 
that the Chimango removes its young when the nest 
has been discovered — a rare habit with birds. 

Chimangos abound most in settled districts, but 
a prospect of food will quickly bring numbers 
together even in the most solitary places. On the 
desert pampas, where hunters, Indian and Euro- 
pean, have a great fancy for burning the dead grass, 
the moment the smoke of a distant fire is seen there 
the Chimangos fly to follow the conflagration. They 
are at such times strangely animated, dashing 
through clouds of smoke, feasting among the hot 
ashes on roasted cavies and other small mammals, 
and boldly pursuing the scorched fugitives from the 
flames. 

At all times and in all places the Chimango is ever 
ready to pounce on the weak, the sickly, and the 
wounded. In other regions of the globe these 
doomed ones fall into the clutches of the true bird 
of prey ; but the salutary office of executioner is 
so effectually performed by the Chimango and his 
congeners where these false Hawks abound, that the 
true Hawks have a much keener struggle to exist 



66 BIRDS OF LA PLATA 

here» This circumstance has possibly served to 
make them swifter of wing, keener of sight, and 
bolder in attack than elsewhere. I have seen a 
Buzzard, which is not considered the bravest of the 
Hawks, turn quick as lightning on a Spur-wing 
Lapwing, which was pursuing it, and, grappling it, 
bear it down to the ground and despatch it in a 
moment, though a hundred other Lapwings were 
uttering piercing screams above it. Yet this Plover 
is a large, powerful, fierce-tempered bird, and armed 
with sharp spurs on its wings. This is but one of 
numberless instances I have witnessed of the extreme 
strength and daring of our Hawks. 

When shooting birds to preserve I used to keep 
an anxious eye on the movements of the Chimangos 
flying about, for I have had some fine specimens 
carried off or mutilated by these omnipresent robbers. 
One winter day I came across a fine Myiotheretes 
rufiventris, a pretty and graceful Tyrant-bird, rather 
larger than the Common Thrush, with a chocolate 
and silver-grey plumage. It was rare in that place, 
and, anxious to secure it^ I fired a very long shot, 
for it was extremely shy. It rose up high in the air 
and flew off apparently unconcerned. What then 
was my surprise to see a Chimango start off in 
pursuit of it ! Springing on to my horse I followed, 
and before going half a mile noticed the Tyrant-bird 
beginning to show signs of distress. After avoiding 
several blows aimed by the Chimango, it flew down 
and plunged into a cardoon bush. There I captured 
itf and when skinning it to preserve found that one 



COMMON CARRION HAWK 67 

small shot had lodged in the fleshy portion of the 
breast. It was a very slight wound^ yet the Chimango 
with its trained sight had noticed something wrong 
with the bird from the moment it flew off, apparently 
in its usual free, buoyant manner. 

On another occasion I was defrauded of a more 
valuable specimen than the Tyrant-bird, It was on 
the east coast of Patagonia, when one morning, while 
seated on an elevation, watching the waves dashing 
themselves on the shore, I perceived a shining white 
object tossing about at some distance from land. 
Successive waves brought it nearer, till at last it was 
caught up and flung far out on to the shingle fifty 
yards from where I sat ; and instantly, before the 
cloud of spray had vanished, a Chimango dashed 
down upon it. I jumped up and ran down as fast as 
I could, and found my white object to be a Penguin, 
apparently just killed by some accident out at sea, and 
in splendid plumage ; but alas ! in that moment the vile 
Chimango had stripped off and devoured the skin from 
its head, so that as a specimen it was hopelessly ruined. 

As a rule, strong healthy birds despise the Chi- 
mango ; they feed in his company ; his sudden 
appearance causes no alarm, and they do not take 
the trouble to persecute him ; but when they have 
eggs or young he is not to be trusted. He is not 
easily turned from a nest he has once discovered. 
I have seen him carry off a young Tyrant-bird 
(Milvulus tyrannus) in the face of such an attack 
from the parent birds that one would have imagined 
not even a true Hawk could have withstood. 



68 BIRDS OF LA PLATA 

Curiously enough, like one of the boldest of our 
small Hawks (Tinnunculus cinnamominus)^ they some- 
times attack birds so much too strong and big for 
them that they must know the assault will produce 
more annoyance than harm. I was once watching 
a flock of Coots feeding on a grassy bank, when a 
passing Chimango paused in its flight, and, after 
hovering over them a few moments, dashed down 
upon them with such impetuosity that several birds 
were thrown to the ground by the quick successive 
blows of its wings. There they lay on their backs, 
kicking, apparently too much terrified to get up, 
while the Chimango deliberately eyed them for 
some moments, then quietly flew away, leaving them 
to dash into the water and cool their fright. Attacks 
like these are possibly made in a sportive spirit, for 
the Milvago is a playful bird, and, as with many 
other species, bird and mammal, its play always 
takes the form of attack. 

Its inefficient weapons compel it to be more timid 
than the Hawk, but there are many exceptions, and 
in every locality individual birds are found dis- 
tinguished by their temerity. Almost any shepherd 
can say that his flock is subject to the persecutions 
of at least one pair of lamb-killing birds of this 
species. They prowl about the flock, and watch till 
a small lamb is found sleeping at some distance from 
its dam, rush upon it, and, clinging to its head, eat 
away its nose and tongue. The shepherd is then 
obliged to kill the lamb ; but I have seen many 
lambs that have been permitted to survive the 



COMMON CARRION HAWK 69 

mutilation, and which have grown to strong healthy 
sheep, though with greatly disfigured faces. One 
more instance I will give of the boldness of a bird 
of which Azara, greatly mistaken, says that it might 
possibly have courage enough to attack a mouse, 
though he doubts it. Close to my house, when I 
was a boy, a pair of these birds had their nest near 
a narrow path leading through a thicket of giant 
thistles, and every time I traversed this path the 
male bird, which, contrary to the rule with birds of 
prey, is larger and bolder than the female, would 
rise high above me, then dashing down strike my 
horse a violent blow on the forehead with its wings. 
This action it would repeat till I was out of the path, 
I thought it very strange the bird never struck my 
head ; but I presently discovered that it had an 
excellent reason for what it did. The gauchos ride 
by preference on horses never properly tamed, and 
one neighbour informed me that he was obliged 
every day to make a circuit of half a mile round the 
thistles, as the horses he rode became quite un- 
manageable in the path, they had been so terrified 
with the attacks of this Chimango, 

Where the intelligence of the bird appears to be 
really at fault is in its habit of attacking a sore- 
backed horse, tempted thereto by the sight of a raw 
spot, and apparently not understanding that the 
flesh it wishes to devour is an inseparable part of 
the whole animal, Darwin has noticed this curi- 
ous blunder of the bird ; and I have often seen a 
chafed saddle-horse wildly scouring the plain closely 



70 BIRDS OF LA PLATA 

pursued by a hungry Chi#^ngo, determined to dine 
on a portion of him. 

In the hot season^ when marshes and lagoons are 
drying up, the Chimango is seen associating with 
Ibises and other waders, standing knee-deep in the 
water and watching for tadpoles, frogs, and other 
aquatic prey. He also wades after a very different 
kind of food. At the bottom of pools, collected on 
clayey soil after a summer shower, an edible fungus 
grows, of a dull greenish colour and resembling 
gelatine. He has found out that this fungus is good 
for food, though I never saw any other creature 
eating it. In cultivated districts he follows the plough 
in company with the Black-headed Gulls, Molothri^ 
Guira Cuckoos, and Tyrant-birds, and clumsily 
gleans amongst the fresh-turned mould for worms 
and larvae. He also attends the pigs when they are 
rooting on the plain to share any succulent treasure 
turned up by their snouts ; for he is not a bird that 
allows dignity to stand between him and his dinner. 
In the autumn, on damp, sultry days, the red ants, 
that make small conical mounds on the pampas, 
are everywhere seen swarming. Rising high in the 
air they form a little cloud or column, and hang 
suspended for hours over the same spot. On such 
days the Milvagos fare sumptuously on little insects, 
and under each cloud of winged ants several of them 
are to be seen in company with a few Flycatchers, 
or other diminutive species, briskly running about 
to pick up the falling manna, their enjoyment un- 
disturbed by any sense of incongruity. 



COMMON CARRION HAWK 71 

Before everything, however, the Chimango is a 
vulture, and is to be found at every solitary rancho 
sharing with dogs and poultry the offal and waste 
meat thrown out on the dust-heap ; or, after the 
flock has gone to pasture, tearing at the eyes and 
tongue of a dead lamb in the sheepfold. When the 
hide has been stripped from a dead horse or cow on 
the plains, the Chimango is always first on the scene. 
While feeding on a carcase it incessantly utters a 
soliloquy of the most lamentable notes, as if pro- 
testing against the hard necessity of having to put 
up with such carrion fare — long querulous cries 
resembling the piteous whines of a shivering puppy 
chained up in a bleak backyard and all its wants 
neglected, but infinitely more doleful in character. 
The gauchos have a saying comparing a man who 
grumbles at good fortune to the Chimango crying 
on a carcase — an extremely expressive saying to 
those who have listened to the distressful wailings 
of the bird over its meat. In winter a carcase attracts 
a great concourse of the Black-backed Gulls ; for 
with the cold weather these Vultures of the sea 
abandon their breeding-places on the Atlantic shores 
to wander in search of food over the vast inland 
pampas. The dead beast is quickly surrounded by a 
host of them, and the poor Chimango crowded out. 
One at least, however, is usually to be seen perched 
on the carcase tearing at the flesh, and at intervals 
with outstretched neck and ruffied-up plumage 
uttering a succession of its strange wailing cries, 
reminding one of a public orator mounted on a 



72 BIRDS OF LA PLATA 

rostrum and addressing narrowing appeals to a 
crowd of attentive listeners. When the carcase has 
been finally abandoned by foxes^ armadillos, Gulls, 
and Caranchos, the Chimango still clings sorrow- 
fully to it, eking out a miserable existence by tear- 
ing at a fringe of gristle and whetting his hungry 
beak on the bones. 

Though an inordinate lover of carrion, a wise 
instinct has taught it that this aliment is unsuited to 
the tender stomachs of its fledglings ; these it feeds 
almost exclusively on the young of small birds. In 
November the Chimangos are seen incessantly beat- 
ing over the cardoon bushes, after the manner of 
Hen-Harriers ; for at this season in the cardoons 
breeds the Synallaxis hudsoni. This bird, sometimes 
called Teru-reru del campo by the natives, is exces- 
sively shy and mouse-like in habits, seldom showing 
itself, and by means of strong legs and a long, slender, 
wedge-like body is able to glide swiftly as a snake 
through and under the grass. In summer one hears 
its long, melancholy, trilling call-note from a cardoon 
bush, but if approached it drops to the ground and 
vanishes. Under the densest part of the cardoon 
bush it scoops out a little circular hollow in the soil, 
and constructs over it a dome of woven grass and 
thorns, leaving only a very small aperture ; it lines 
the floor with dry horse-dung, and lays five buff- 
coloured eggs. So admirably is the nest concealed 
that I have searched every day for it through a whole 
breeding-season without being rewarded with a 
single find. Yet they are easily found by the Chi- 



COMMON CARRION HAWK 73 

mango* In the course of a single day I have examined 
five or six broods of young Chimangos, and by 
pressing a finger on their distended crops made them 
disgorge their food, and found in every instance 
that they had been fed on nothing but the young of 
the Teru-reru, I was simply ama2;ed at this whole- 
sale destruction of the young of a species so secret 
in its nesting-habits ; for no eye, even of a Hawk, 
can pierce through the leafage of a cardoon bush, 
ending near the surface in an accumulated mass of 
the dead and decaying portions of the plant* The 
explanation of the Chimango's success is to be found 
in the loquacious habit of the fledglings it preys on, 
a habit common in the young of Dendrocolaptine 
species* The intervals between the visits of the parent 
birds with food they spend in conversing together 
in their high-pitched tones. If a person approaches 
the solid fabric of the Oven-bird (Furnarius rufus) 
when there are young in it, he will hear shrill laughter- 
like notes and little choruses, like those uttered by 
the old birds, only feebler ; but in the case of that 
species no harm can result from the loquacity of 
the young, since the castle they inhabit is impreg- 
nable. Hovering over the cardoons, the Chimango 
listens for the stridulous laughter of the fledglings, 
and when he hears it the thorny covering is quickly 
pierced and the dome broken into. 

Facts like these bring before us with startling 
vividness the struggle for existence, showing what 
great issues in the life of a species may depend on 
matters so trivial, seemingly, that to the uninformed 



74 BIRDS OF LA PLATA 

mind they appear like th^fierest dust in the balance, 
which is not regarded. And how tremendous and 
pitiless is that searching law of the survival of the 
fittest in its operations, when we see a species like 
this SynallaxiSf in the fashioning and perfecting of 
which Nature seems to have exhausted all her art, so 
exquisitely is it adapted in its structure, coloration, 
and habits to the one great object of concealment, 
yet apparently doomed to destruction through this 
one petty oversight — the irrepressible garrulity of 
the fledglings in their nest ! It is, however, no over- 
sight at all ; since the law of natural selection is not 
prophetic in its action, and only preserves such 
variations as are beneficial in existing circumstances, 
without anticipating changes in the conditions. The 
settlement of the country has, no doubt, caused a 
great increase of Chimangos, and in some indirect 
way probably has served to quicken their intelligence ; 
thus a change in the conditions which have moulded 
this Synallaxis brings a danger to it from an un- 
expected quarter. The situation of the nest exposes 
it, one would imagine, to attacks from snakes and 
small mammals, from bird-killing spiders, beetles 
and crickets, yet these subtle ground foes have 
missed it, while the baby-laughter of the little ones 
in their cradle has called down an unlooked-for 
destroyer from above. It might be answered that 
this must be a very numerous species, otherwise 
the Chimango could not have acquired the habit 
of finding the nests ; that when they become rarer 
the pursuit will be given over, after which the balance

will readjust itself. But in numbers there is safety, 
especially for a feeble, hunted species, unable from 
its peculiar structure to vary its manner of life. To 
such the remark made by Darwin, that '' rarity is 
the precursor to extinction/' applies with peculiar 
force. 



CARANCHO OR CARACARA 

Polyborus tharus 

Dark brown with whitish mottlings ; head black ; wings and tail 
greyish white with greyish brown cross-bars and black tips ; beneath 
dark brown ; throat and sides of head yellowish white ; beak yellow ; 
cere orange. Sexes alike. 

This bird, which combines the raptorial instincts 
of the Eagle with the base carrion-feeding habits of 
the Vulture, has already had so many biographers 
that it might seem superfluous to speak of it again at 
any great length ; only it happens to be one of those 
very versatile species about which there is always 
something fresh to be said ; and, besides, I do not 
altogether agree with the very ignoble character 
usually ascribed to it by travellers. It is, however, 
probable that it varies greatly in disposition and 
habits in different districts. In Patagonia I was 
surprised at its dejected appearance and skulking 
cowardly manner, so unlike the bird I had been 
accustomed to see on the pampas. I shot several, 
and they were all in a miserably poor condition and 
apparently half-starved. It struck me that in that 



76 BIRDS OF LA PLATA 

cold, sterile country, wh^ prey is scarce, the Ca- 
rancho is altogether out of place ; for it there has to 
compete with Eagles and Vultures in large numbers ; 
and these, it is almost needless to say, are, in their 
separate lines, stronger than the composite and less 
specialised Carancho. In Patagonia he is truly a 
** miserable bird," with a very frail hold on existence. 
How different on that illimitable grassy ocean farther 
north, where he is the lord of the feathered race, 
for Eagles and Vultures, that require mountains 
and trees to breed and roost on, do not come there 
to set him aside ; there the conditions are suited to 
him and have served to develop in him a wonderfully 
bold and savage spirit. When seen perched on a 
conical ant-hill, standing erect above the tall plumy 
grass, he has a fine, even a noble appearance ; but 
when flying he is not handsome, the wings being 
very bluntly rounded at the extremities and the 
flight low and ungraceful. The plumage is blackish 
in the adult, brown in the young. The sides of the 
head and breast are creamy white, the latter trans- 
versely marked with black spots. The crown is 
adorned with a crest or top-knot. The beak is much 
larger than in Eagles and Vultures, and of a dull 
blue colour ; the cere and legs are bright yellow. 

The species ranges throughout South America, 
and from Paraguay northwards is called every- 
where, I beheve, Caracara, South of Paraguay the 
Spanish name is Carancho, possibly a corruption of 
Keanche, the Puelche name for the allied Milvago 
chimango, in imitation of its peevish cry. The 



CARANCHO 77 

Indian name for the Carancho in these regions 
is Tram (from its harsh cry), misspelt Tharu by 
Molina, a Spanish priest who wrote a book on the 
birds of Chili in the eighteenth century ; hence the 
specific name tharus. 

The Caranchos pair for life, and may therefore be 
called social birds ; they also often live and hunt in 
families of the parent and young birds until the 
following spring ; and at all times several individuals 
will readily combine to attack their prey, but they 
never live or move about in flocks* Each couple 
has its own home or resting-place, which they will 
continue to use for an indefinite time, roosting on 
the same branch and occupying the same nest year 
after year ; while at all times the two birds are seen 
constantly together and seem very much attached, 
Azara relates that he once saw a male pounce down 
on a frog, and carrying it to a tree call his mate to 
him and make her a present of it. It was not a very 
magnificent present, but the action seems to show 
that the bird possesses some commendable qualities 
which are seldom seen in the raptorial family. 

In uninhabited places I have always found the 
Caranchos just as abundant as in the settled districts ; 
and after a deer has been pulled down by the dogs 
I have seen as many as seventy or eighty birds 
congregate to feed on its flesh within half an hour, 
although not one had been previously visible. 
D'Orbigny describes the bird as a parasite on man, 
savage and civilised, following him everywhere to 
feed on the leavings when he slays wild or domestic 



78 BIRDS OF LA PLATA 

animals, and as being scarcely able to exist without 
him. No doubt the bird does follow man greatly 
to its advantage, but this is only in very thinly 
settled and purely pastoral and hunting districts, 
where a large proportion of the flesh of every animal 
slain is given to the fowls of the air. Where the 
population increases the Carancho quickly meets 
with the fate of all large species which are regarded 
as prejudicial. 

Without doubt it is a carrion-eater, but only, I 
believe, when it cannot get fresh provisions ; for 
when famished it will eat anything rather than study 
its dignity and suffer hunger like the nobler Eagle. 
I have frequently seen one or two or three of them 
together on the ground under a column of winged 
ants, eagerly feasting on the falling insects. To 
eat putrid meat it must be very hungry indeed ; it 
is, however, amazingly fond of freshly-killed flesh, 
and when a cow is slaughtered at an estancia-house 
the Carancho quickly appears on the scene to claim 
his share, and catching up the first thing he can 
lift he carries it off before the dogs can deprive him 
of it. When he has risen to a height of five or six 
yards in the air he drops the meat from his beak 
and dexterously catches it in his claws without 
pausing or swerving in his flight. It is singular 
that the bird seems quite incapable of lifting anything 
from the ground with the claws, the beak being 
invariably used, even when the prey is an animal 
which it might seem dangerous to lift in this way. 
I once saw one of these birds swoop down on a rat 



CARANCHO 79 

from a distance of about forty feet, and rise with 
its struggling and squealing prey to a height of twenty 
feet, then drop it from his beak and gracefully catch 
it in his talons. Yet when it pursues and overtakes 
a bird in the air it invariably uses the claws in the 
same way as other Hawks, This I have frequently 
observed, and I give the two following anecdotes to 
show that even birds which one would imagine to 
be quite safe from the Carancho are on some occa- 
sions attacked by it. 

While walking in a fallow field near my home one 
day I came on a Pigeon feeding, and at once recog- 
nised it as one which had only begun to fly about a 
week before ; for although a large number of Pigeons 
were kept, this bird happened to be of the purest 
unspotted white, and for a long time I had been 
endeavouring to preserve and increase the pure white 
individuals, but with very little success, for the 
Peregrines invariably singled them out for attack. 
A Carancho was circling about at some distance 
overhead, and while I stood still to watch and admire 
my Pigeon it stooped to within twenty yards of the 
surface and remained hovering over my head. 
Presently the Pigeon became alarmed and flew 
away, whereupon the Hawk gave chase— a very 
vain chase I imagined it would prove. It lasted 
for about half a minute, the Pigeon rushing wildly 
round in wide circles, now mounting aloft and now 
plunging downwards close to the surface, the 
Carancho hotly following all the time. At length, 
evidently in great terror, the hunted bird flew down, 



8o BIRDS OF LA PLATA 

alighting within a yard of ^ feet. I stooped to take 
hold of it, when, becoming frightened at my action, 
it flew straight up and was sei2:ed in the talons of 
its pursuer close to my face and carried away. 

In the next case the bird attacked was the Spur- 
winged Lapwing, the irreconcilable enemy of the 
Carancho and its bold and persistent persecutor. 
The very sight of this Hawk rouses the Lapwings 
to a frenzy of excitement, and springing aloft they 
hasten to meet it in mid-air, screaming loudly, and 
continue to harry it until it leaves their ground, 
after which they return, and, ranged in triplets, 
perform their triumphal dances, accompanied with 
loud drumming notes. But if their hated foe alights 
on the ground, or on some elevation near them, they 
hover about him, and first one, then another, rushes 
down with the greatest violence, and gliding near 
him turns the bend of its wings so that the spur 
appears almost to gra2;e his head. While one bird is 
descending others are rising upwards to renew their 
charges ; and this persecution continues until they 
drive him away or become exhausted with their 
fruitless efforts. The Carancho, however, takes 
little notice of his tormentors ; only when the Plover 
comes very close, evidently bent on piercing his 
skull with its sharp weapon, he quickly dodges his 
head, after which he resumes his indifferent de- 
meanour until the rush of the succeeding bird takes 
place. 

While out riding one day a Carancho flew past 
me attended by about thirty Lapwings, combined to 



CARANCHO 8i 

hunt him from their ground, for it was near the 
breeding-season, when their jealous irascible temper 
is most excited. All at once, just as a Lapwing swept 
close by and then passed on before it, the Hawk 
quickened its flight in the most wonderful manner 
and was seen in hot pursuit of its tormentor. The 
angry hectoring cries of the Lapwings instantly 
changed to piercing screams of terror, which in a 
very short time brought a crowd numbering between 
two and three hundred birds to the rescue. Now, 
I thought, the hunted bird will escape, for it twisted 
and turned rapidly about, trying to lose itself amongst 
its fellows, all hovering in a compact crowd about 
it and screaming their loudest. But the Carancho 
was not to be shaken off; he was never more than 
a yard behind his quarry, and I was near enough to 
distinguish the piteous screams of the chased Lap- 
wing amidst all the tumult, as of a bird already 
captive. At the end of about a minute it was seized 
in the Carancho's talons, and, still violently scream- 
ing, borne away. The cloud of Lapwings followed 
for some distance, but presently they all returned 
to the fatal spot where the contest had taken 
place ; and for an hour afterwards they continued 
soaring about in separate bodies, screaming all the 
time with an unusual note in their voices as of 
fear or grief, and holding excited conclaves on 
the ground, to all appearance as greatly disturbed 
in their minds as an equal number of highly 
emotional human beings would be in the event 
of a similar disaster overtaking them. 

F II 



82 BIRDS OF LA PLATA 

It is not often^ however, that the Carancho ventures 
singly to attack adult and vigorous birds, except 
the Tinamu, the ** Partridge " of South America ; 
they prey by preference on the young and ailing, 
on small lambs and pigs left at a distance by their 
dams ; and they also frequently attack and kill 
old and weakly sheep. Where anything is wrong 
with bird or beast they are very quick to detect it, 
and will follow a sportsman to pick up the wounded 
birds, intelligently keeping at a safe distance them- 
selves. I once shot a Flamingo in the grey stage of 
plumage and had some trouble to cross the stream, 
on the opposite side of which the bird, wounded 
very slightly, was rapidly stalking away. In three or 
four minutes I was over and found my Flamingo 
endeavouring to defend itself against the assaults of 
a Carancho which had marked it for its own, and 
was striking it on the neck and breast in the most 
vigorous and determined way, sometimes from above, 
at other times alighting on the ground before it and 
springing up to strike like a game-cock. A spot of 
blood on the plumage of the wounded bird, which 
had only one wing slightly damaged, had been 
sufficient to call down the attack ; for to the Carancho 
a spot of blood, a drooping wing, or any irregularity 
in the gait, quickly tells its tale. 

When several of these birds combine they are very 
bold. A friend told me that while voyaging on the 
Parana river a Black-necked Swan flew past him 
hotly pursued by three Caranchos; and I also wit- 
nessed an attack by four birds on a widely different 



CARANCHO 83 

species, I was standing on the bank of a stream on 
the pampas watching a great concourse of birds of 
several kinds on the opposite shore^ where the carcase 
of a horse, from which the hide had been stripped, 
lay at the edge of the water. One or two hundred 
Hooded Gulls and about a do2;en Chimangos were 
gathered about the carcase, and close to them a very 
large flock of Glossy Ibises were wading about in 
the water, while amongst these, standing motionless 
in the water, was one solitary White Egret. Presently 
four Caranchos appeared, two adults and two young 
birds in brown plumage, and alighted on the ground 
near the carcase. The young birds advanced at once 
and began tearing at the flesh ; while the two old 
birds stayed where they had alighted, as if disinclined 
to feed on half-putrid meat. Presently one of them 
sprang into the air and made a dash at the birds in 
the water, and instantly all the birds in the place 
rose into the air screaming loudly, the two young 
brown Caranchos only remaining on the ground. 
For a few moments I was in ignorance of the mean- 
ing of all this turmoil, when, suddenly, out of the 
confused black and white cloud of birds the Egret 
appeared, mounting vertically upwards with vigorous 
measured strokes. A moment later, first one then 
the other Carancho also emerged from the cloud, 
evidently pursuing the Egret, and only then the two 
brown birds sprang into the air and joined in the 
chase. For some minutes I watched the four birds 
toiling upwards with a wild zig-zag flight, while the 
Egret, still rising vertically, seemed to leave them 



84 BIRDS OF LA PLATA 

hopelessly far behind. But before long they reached 
and passed it, and each bird as he did so would turn 
and rush downwards, striking at the Egret with his 
claws, and while one descended the others were 
rising, bird following bird with the greatest regularity. 
In this way they continued toiling upwards until the 
Egret appeared a mere white speck in the sky, about 
which the four hateful black spots were still revolv- 
ing. I had watched them from the first with the 
greatest excitement, and now began to fear that they 
would pass from sight and leave me in ignorance of 
the result ; but at length they began to descend, 
and then it looked as if the Egret had lost all hope, 
for it was dropping very rapidly, while the four birds 
were all close to it, striking at it every three or four 
seconds. The descent for the last half of the distance 
was exceedingly rapid, and the birds would have 
come down almost at the very spot they started from, 
which was about forty yards from where I stood, but 
the Egret was driven aside, and sloping rapidly down 
struck the earth at a distance of two hundred yards 
from the starting-point. Scarcely had it touched the 
ground before the hungry quartet were tearing it 
with their beaks. They were all equally hungry no 
doubt, and perhaps the old birds were even hungrier 
than their young ; and I am quite sure that if the 
flesh of the dead horse had not been so far advanced 
towards putrefaction they would not have attempted 
the conquest of the Egret. 

I have so frequently seen a pure white bird singled 
out for attack in this way, that it has always been a 



CARANCHO 85 

great subject of wonder to me how the two common 
species of snow-white Herons in South America are 
able to maintain their existence ; for their whiteness 
exceeds that of other white waterfowl^ while, com- 
pared with Swans, Storks, and the Wood-Ibis, they 
are small and feeble. I am sure that if these four 
Caranchos had attacked a Glossy Ibis they would 
have found it an easier conquest ; yet they singled 
out the Egret, purely, I believe, on account of its 
shining white conspicuous plumage. 

This wing-contest was a very splendid spectacle, 
and I was very glad that I had witnessed it, although 
it ended badly for the poor Egret ; but in another 
case of a combined attack by Caranchos there was 
nothing to admire except the intelligence displayed 
by the birds in combining, and much to cause the 
mind to revolt against the blindly destructive ferocity 
exhibited by Nature in the instincts of her creatures. 
The scene was witnessed by a beloved old gaucho 
friend of mine, a good observer, who related it to 
me. It was in summer, and he was riding in a 
narrow bridle-path on a plain covered with a dense 
growth of giant thistles, nine or ten feet high, when 
he noticed some distance ahead several Caranchos 
hovering over the spot ; and at once conjectured 
that some large animal had fallen there, or that a 
traveller had been thrown from his horse and was 
lying injured among the thistles. On reaching the 
spot he found an open space of ground about forty 
yards in diameter, surrounded by the dense wall 
of close-growing thistles, and over this place the birds 



86 BIRDS OF LA PLATA 

were flyings while several others were stationed near, 
apparently waiting for something to happen. The 
attraction was a large male Rhea squatting on the 
ground, and sheltering with its extended wings a 
brood of young birds. My friend was not able to 
count them, but there were not fewer than twenty- 
five or thirty young birds, small tender things, only 
a day or so out of the shelL As soon as he rode into 
the open space of ground, the old Ostrich sprang 
up, and with lowered head, clattering beak, and 
broad wings spread out like sails, rushed at him ; 
his horse was greatly terrified, and tried to plunge 
into the dense mass of thistles, so that he had the 
greatest difficulty in keeping his seat. Presently the 
Ostrich left him, and casting his eyes round he was 
astonished to see that all the young Ostriches were 
running about, scattered over the ground, while the 
Caranchos were pursuing, knocking down, and killing 
them. Meanwhile the old Ostrich was frantically 
rushing about trying to save them ; but the Ca- 
ranchos, when driven from one bird they were 
attacking, would merely rise and drop on the next 
one a dozen yards off; and as there were about 
fifteen Caranchos all engaged in the same way, 
the slaughter was proceeding at a great rate. My 
friend, who had been vainly struggling to get the 
better of his horse, was then forced to leave the 
place, and did not therefore see the end of the tragedy 
in which he had acted an involuntary part ; but 
before going he saw that at least half the young birds 
were dead, and that these were all torn and bleed- 



CARANCHO 87 

ing on the small of the neck just behind the head, 
while in some cases the head had been completely 
wrenched off. 

The Gauchos when snaring Partridges (Tinamus) 
frequently bribe the Caranchos to assist them. The 
snarer has a long slender cane with a small noose at 
the extremity, and when he sights a Partridge he 
gallops round it in circles until the bird crouches 
close in the grass ; then the circles are narrowed 
and the pace slackened, while he extends the cane 
and lowers it gradually over the bewildered bird 
until the small noose is dropped over its head 
and it is caught. Many Partridges are not dis- 
posed to sit still to be taken in this open, bare- 
faced way ; but if the snarer keeps a Carancho 
hovering about by throwing him an occasional 
gizzard, the wariest Partridge is so stricken with 
fear that it will sit still and allow itself to be 
caught. 

In the love season the male Caranchos are fre- 
quently seen fighting ; and sometimes, when the 
battle is carried on at a great height in the air, the 
combatants are seen clasped together and falling 
swiftly towards the earth ; but, in all contests I have 
witnessed, the birds have not been so blinded with 
passion as to fall the whole distance before separating. 
Besides these single combats, in which unpaired or 
jealous males engage in the love-season, there are 
at all times occasional dissensions amongst them, 
the cause of which it would be difficult to determine. 
Here again, as often in hunting, the birds combine 



88 BIRDS OF LA PLATA 

to punish an offender, and in some cases the punish- 
ment is death. 

Their cry is exceedingly loud and harsh, a short 
abrupt note, like cruk, repeated twice ; after which, 
if the bird is violently agitated, as when wounded or 
fighting, it throws its head backwards until the crown 
rests on the back, and rocks it from side to side, 
accompanying the action with a prolonged piercing 
cry of great power. This singular gesture of the 
Carancho, unique among birds, seems to express 
very forcibly a raging spirit. 

The nest is built in a variety of situations : on 
trees, where there are any, but on the treeless pampas, 
where the Carancho is most at home, it is made on 
the ground, sometimes among the tall grass, while 
a very favourite site is a small islet or mound of 
earth rising well out of the water. When a suitable 
place has been found, the birds will continue to use 
the same nest for many consecutive years. It is a 
very large, slovenly structure of sticks, mixed with 
bones, pieces of skin, dry dung, and any portable 
object the bird may find to increase the bulk of his 
dwelling. The eggs are three or four, usually the 
last number, slightly oval, and varying greatly in 
colour and markings, some having irregular dark red 
blotches on a cream-coloured ground, while others 
are entirely of a deep brownish red, with a few black 
marks and blotches. 



BLACK VULTURE 89 



BLACK VULTURE 

Cathartes atratus 

Whole plumage black ; head bare and black ; length 25 inches, 
wing 17.5 inches. 

Three species of Vulture inhabit Argentina, all of 
the American family Cathartids ; the first being 
the Great Condor, Sarcorhamphus gryphus^ found in 
the Andean region and in Patagonia. Of this great 
and often-described bird I can say next to nothing 
from personal observation, as I met with it but once, 
and that was on the sea-shore south of the Rio Negro. 
The second is the well-known Turkey Bu2;zard of 
southern North America, Cathartes aura* His range 
extends south to Patagonia, where I met with it and 
could always distinguish it from the common Black 
Vulture at a great distance by its bright red, bare 
head and neck. It is, however, far from common. 

The Black Vulture, according to Dr. Burmeister, 
is found throughout the Argentine pampas, but is 
commoner in the east and north. It is known as the 
Gallinazo at Mendoza, and Cuervo (Crow) in Tucu- 
man. Mr. Barrows tells us that he did not see it 
during his residence at Concepcion, but was told of 
its former abundance in times of drought, when 
dead sheep were numerous. It was, however, met 
with by him in small numbers during his excursion 
through the sierras of the pampas south of Buenos 
Ayres. 

On the Rio Negro in Patagonia I found these 



90 BIRDS OF LA PLATA 

Vultures abundant, espeoally near the settlement of 
El Carmen, where, attracted by the refuse of the 
cattle-slaughtering establishments, they congregated 
in immense numbers, and were sometimes seen 
crowded together in thousands on the trees, where 
they roosted. Darwin observed them at the same 
place, and has described their soaring habits at 
considerable length* 

The following account of the nesting habits of 
this species is given by Mr. John J. Dalgleish 
{Proc* Roy* Phys. Soc, Edin,, vi. 237) : '' The eggs 
seldom, if ever, exceed two in number, and are 
usually laid in a hollow tree or on the ground. Their 
average weight is about a pound. They are slightly 
larger than those of the Turkey Buzzard, although 
the latter is a bigger bird. The ground colour is of 
a yellowish white, with blotches of dark reddish 
brown, and smaller markings of a lilac shade. These 
markings are generally more numerous at the larger 
end/' 



BRAZILIAN CORMORANT 

Phalacrocorax brasilianm 

Black, glossed with metallic green ; bill and naked skin of the face 
yellow ; length 30 inches, wing 12 inches. Female similar ; young 
brown, cheeks whitish and breast white. 

This appears to be the only Cormorant met with 
on the coasts and inland waters of South America, 
north of Buenos Ayres ; but two other species are 
found in southern Chili and Patagonia, which may 



BRAZILIAN CORMORANT 91 

probably likewise occur in the southern provinces 
of the Republic*^ 

Azara tells us that this Cormorant is not un- 
common in Paraguay^ and Mr* Barrows found it an 
** abundant resident *' at Concepcion in Entrerios. 

In the vicinity of Buenos Ayres several well-known 
authorities have met with it> and Durnford found 
it common and resident in Chupat, 

The name of Bradlian Cormorant, which natur- 
alists have bestowed on this species, is certainly 
inappropriate and misleading, since the bird is very 
abundant in La Plata, where the native name for it 
is Vigua ; and it is also very common in the Pata- 
gonian rivers. It is always seen swimming, sinking 
its heavy body lower and lower down in the water 
when approached, until only the slanting snake-like 
head and neck are visible ; or else sitting on the bank, 
or on a dead projecting branch, erect and with raised 
beak, and never moving from its statuesque attitude 
until forced to fly. It rises reluctantly and with great 
labour, and has a straight rapid flight, the wings 
beating incessantly. By day it is a silent bird, but 
when many individuals congregate to roost on the 
branches of a dead tree overhanging the river, they 
keep up a concert of deep, harsh, powerful notes 
all night long, which would cause any person not 
acquainted with their language to imagine that 
numerous pigs or peccaries were moving about with 
incessant gruntings in his neighbourhood. 

* Namely, P. imperialis and P. albiventris. See Zool. Chall. (Birds), 
p. 121. It was probably one of these two species that Durnford found 
nesting on Tombo Point, south of Chupat (c/. Ibis, 1878, p. 399). 



92 BIRDS OF LA PLATA 



COCOI HERON 

Ardea cocoi 

Above grey ; head, wings, and tail slatey black ; beneath white ; 
neck and sides striped with black ; length 36 inches, wing 18 inches, 
tail 7 inches. Sexes alike. 

This fine Heron is found throughout South and 
some parts of North America. In size, form, and 
colour it closely resembles the Common Heron of 
Europe ; in flight, language, and feeding-habits the 
two species are identical, albeit inhabiting regions 
so widely separated. In the southern part of South 
America it is not seen associating with its fellows, 
nor does it breed in heronries ; but this may be 
owing to the circumstance that in the temperate 
countries it is very thinly distributed ; and it is 
highly probable, I think, that in the hotter regions, 
where it is more abundant, its habits may not appear 
so unsocial. Though they are always seen fishing 
singly, they pair for life, and male and female are 
never found far apart, but haunt the same stream 
or marsh all the year round. A^ara says that in 
Paraguay, where they are rare, they go in pairs and 
breed in trees. On the pampas it makes its solitary 
nest amongst the rushes, and lays three blue eggs. 

The following general remarks on the Heron 
apply chiefly to the Ardea cocoi, and to some extent 
also to other species of the Heron family. 

I have observed Herons of several species a good 



COCOI HERON 93 

deal, but chiefly the Cocoi, and think there is some- 
thing to be said in support of Buffon's opinion that 
they are wretched, indigent birds, condemned by 
the imperfection of their organs to a perpetual 
struggle with want and misery. In reality the organs, 
and the correlated instincts, are just as perfect as in 
any other creature, but the Heron is certainly more 
highly specialised and lives more in a groove than 
most species. Consequently when food fails him in 
the accustomed channels he suffers more than most 
other species. 

Much as the different species vary in size, from 
the Ardea cocoi to the diminutive Variegated Heron 
of Azara (Ardetta involucris)^ no bigger than a Snipe, 
there is yet much sameness in their conformation, 
language, flight, nesting and other habits. They 
possess a snake-like head and neck, and a sharp 
taper beak, with which they transfix their prey as 
with a dart — also the serrate claw, about which so 
much has been said, and which has been regarded as 
an instance of pure adaptation. 

A curious circumstance has come under my obser- 
vation regarding Herons. Birds in poor condition are 
very much infested with vermin ; whether the ver- 
min are the cause or effect of the poor condition, I do 
not know ; but such is the fact. Now in this region 
(the Argentine Republic) Herons are generally very 
poor, a good-conditioned bird being a very rare 
exception ; a majority of individuals are much 
emaciated and infested with intestinal worms ; yet I 
have never found a bird infested with lice, though the 



94 BIRDS OF LA PLATA 

Heron would seem a fit ^tbject for them^ and in the 
course of my rambles I have picked up many in- 
dividuals apparently perishing from inanition. I do 
not wish to insinuate a behef that this immunity from 
vermin is due to the pectinated claw ; for though the 
bird does scratch and clean itself with the claw it 
could never rid the entire plumage from vermin by 
this organ, which is as ill adapted for such a purpose 
as for ** giving a firmer hold on its slippery prey/' 

The Spoonbill has also the serration, and is, unlike 
the Heron, an active vigorous bird and usually fat ; 
yet it is much troubled with parasites, and I have 
found birds too weak to fly and literally swarming 
with them, 

I merely wish to call the attention of ornitholo- 
gists to the fact that in the region where I have 
observed Herons they are exempt in a remarkable 
degree from external parasites. 

Much has also been said about certain patches of 
dense, clammy, yellowish down under the loose 
plumage of Herons. These curious appendages may 
be just as useless to the bird as the tuft of hair on 
its breast is to the Turkey-cock ; but there are more 
probabilities the other way, and it may yet be dis- 
covered that they are very necessary to its well-being. 
Perhaps these clammy feathers contain a secretion 
fatal to the vermin by which birds of sedentary 
habits are so much afflicted, and from which Herons 
appear to be so strangely free. They may even be 
the seat of that mysterious phosphorescent light 
which some one has affirmed emanates from the 



COCOI HERON 95 

Heron^s breast when it fishes in the dark, and which 
serves to attract the fish, or to render them visible 
to the bird* Naturalists have, I believe, dismissed 
the subject of this light as a mere fable without any 
foundation of fact ; but real facts regarding habits 
of animals have not infrequently been so treated. 
Mr. Bartlett's interesting observations on the Flam- 
ingoes in the Society's Gardens show that the ancient 
story of the Pelican feeding its young on its own 
blood is perhaps only a slightly embellished account 
of a common habit of the Flamingo. 

I have not observed Herons fishing by night very 
closely, but there is one fact which inclines me to 
believe it probable that some species might possess 
the light-emitting power in question. I am convinced 
that the Ardea cocoi sees as well by day as other 
diurnal species ; the streams on the level pampas 
are so muddy that a fish two inches below the sur- 
face is invisible to the human eye, yet in these thick 
waters the Herons fish by night and by day. If the 
eye is adapted to see well with the bright sun shining, 
how can it see at night and in such unfavourable 
circumstances without some such extraneous aid to 
vision as the attributed luminosity i 

Herons of all birds have the slowest flight ; but 
though incapable of progressing rapidly when flying 
horizontally, when pursued by a Hawk the Heron 
performs with marvellous ease and grace an aerial 
feat unequalled by any other bird, namely that of 
rising vertically to an amadng height in the air. 
The swift vertical flight with which the pursued 



96 BIRDS OF LA PLATA 

ascends until it become^ mere speck in the blue 
2;enith, the hurried zigzag flight of the pursuer, 
rising every minute above its prey, only to be left 
below again by a single flap of the Heron's wings, 
forms a sight of such grace, beauty, and power as 
to fill the mind of the spectator with delight and 
astonishment. 

When the enemy comes to close quarters, the 
Heron instinctively throws itself belly up to repel 
the assault with its long, crooked, cutting claws* 
Raptorial species possess a similar habit ; and the 
analogous correlation of habit and structure in genera 
so widely separated is very curious. The Falcon 
uses its feet to strike, lacerate, and grasp its prey ; 
the Heron to anchor itself firmly to its perch ; but 
for weapons of defence they are equally well adapted, 
and are employed in precisely the same manner* 
The Heron, with its great length of neck and legs, 
its lean unballasted body, large wings, and super- 
abundance of plumage, is the least suited of birds 
to perch high ; yet the structure of the feet renders 
it perfectly safe for the bird to do so. Thus the 
Heron is enabled to sit on a smooth enamelled rush or 
on the summit of a tree, and doze securely in a wind 
that, were its feet formed like those of other Waders, 
would blow it away like a bundle of dead feathers. 

Another characteristic of Herons is that they carry 
the neck, when flying, folded in the form of the letter 
S. At other times the bird also carries the neck this 
way ; and it is, indeed, in all long-necked species 
the figure the neck assumes when the bird reposes 



COCOI HERON 97 

or is in the act of watching something below it ; and 
the Heron's life is almost a perpetual watch. Apropos 
of this manner of carrying the neck, so natural to the 
bird, is it not the cause of the extreme wariness 
observable in Herons ^ Herons are, I think, every- 
where of a shy disposition ; with us they are the 
wildest of water-fowl, yet there is no reason for their 
being so, since they are never persecuted. 

Birds ever fly reluctantly from danger ; and all 
species possessing the advantage of a long neck, such 
as the Swan, Flamingo, Stork, Spoonbill, etc., will 
continue with their necks stretched to their utmost 
capacity watching an intruder for an hour at a time 
rather than fly away. But in the Herons it must be 
only by a great effort that the neck can be wholly 
unbent ; for even if the neck cut out from a dead 
bird be forcibly straightened and then released, it 
flies back like a piece of india-rubber to its original 
shape. Therefore the effort to straighten the neck, 
invariably the first expression of alarm and curiosity, 
must be a painful one ; and to keep it for any length 
of time in that position is probably as insupportable 
to the bird as to keep the arm straightened vertically 
would be to a man. Thus the Heron flies at the first 
sight of an intruder, whilst the persecuted Duck, 
Swan, or other fowl continues motionless, watching 
with outstretched neck, participating in the alarm 
certainly, but not enduring actual physical pain. 

Doubtless in many cases habits react upon and 
modify the structure of parts ; and in this instance 
the modified structure has in its turn apparently 



gS BIRDS OF LA PLATA 

reacted on and modified me habits. In seeking for 
and taking food, the body is required to perform 
certain definite motions and assume repeatedly the 
same attitudes ; this is most frequently the case in 
birds of aquatic habits. A readiness for assuming at 
all times, and an involuntary falling into, these 
peculiar attitudes and gestures appears to become 
hereditary ; and the species in which they are the 
most noticeable seem incapable of throwing the habit 
or manner off, even when placed in situations where 
it is useless or even detrimental. Tringae rapidly 
peck and probe the mud as they advance ; Plovers 
peck and run, peck and run again. Now I have 
noticed scores of times that these birds cannot possibly 
lay aside this habit of pecking as they advance ; for 
even a wounded Plover running from his pursuer 
over dry barren ground goes through the form of 
eating by pausing for a moment every yard or so, 
pecking the ground, then running on again. 

The Paraguay Snipe, and probably other true 
Snipes, possesses the singular habit of striking its 
beak on the ground when taking flight. In this 
instance has not the probing motion, performed 
instinctively as the bird moves, been utilised to assist 
it in rising i 

Grebes on land walk erect like Penguins and have 
a slow, awkward gait ; and whenever they wish to 
accelerate their progress they throw themselves for- 
ward on the breast and strike out the feet as in 
swimming. 

The Glossy Ibis feeds in shallow water, thrusting 



COCOI HERON 99 

its great sickle beak into the weeds at the bottom at 
every step. When walking on land it observes these 
motions, and seems incapable of progressing without 
plunging its beak downwards into imaginary water 
at every stride* 

The Spoonbill wades up to its knees and advances 
with beak always immersed, and swaying itself from 
side to side, so that at each lateral movement of the 
body the beak describes a great semicircle in the 
water ; a flock of these birds feeding reminds one 
of a line of mowers mowing grass. On dry ground 
the Spoonbill seems unable to walk directly forward 
like other birds, but stoops, keeping the body in a 
horizontal position, and, turning from side to side, 
sweeps the air with its beak, as if still feeding in the 
water. 

In the foregoing instances (and I could greatly 
multiply them) in which certain gestures and move- 
ments accompany progressive motion, it is difficult 
to see how the structure can be in any way modified 
by them ; but the preying attitude of the heron, the 
waiting motionless in perpetual readiness to strike, 
has doubtless given the neck its peculiar form. 

Two interesting traits of the Heron (and they have 
a necessary connection) are its tireless watchfulness 
and its insatiable voracity ; for these characteristics 
have not, I think, been exaggerated even by the 
most sensational of ornithologists. 

In birds of other genera repletion is invariably 
followed by a period of listless inactivity during 
which no food is taken or required. But the Heron 



loo BIRDS OF LA PLATA 

digests his food so rapidly that, however much he 
devours, he is always ready to gorge again ; con- 
sequently he is not benefited so much by what he 
eats, and appears in the same state of semi-starvation 
when food is abundant as in times of scarcity. An 
old naturalist has suggested, as a reason for this, 
that the Heron, from its peculiar manner of taking 
its prey, requires fair weather to fish — that during 
spells of bad weather, when it is compelled to suffer 
the pangs of famine inactive, it contracts a meagre 
consumptive habit of body, which subsequent plenty 
cannot remove. A pretty theory, but it will not hold 
water ; for in this region spells of bad weather are 
brief and infrequent ; moreover, all other species 
that feed at the same table with the Heron, from the 
little flitting Kingfisher to the towering Flamingo, 
become excessively fat at certain seasons, and are at 
all times so healthy and vigorous that, compared with 
them, the Heron is the mere ghost of a bird. In no 
extraneous circumstances, but in the organisation of 
the bird itself, must be sought the cause of its 
anomalous condition ; it does not appear to possess 
the fat-elaborating power, for at no season is any 
fat found on its dry, starved flesh ; consequently 
there is no provision for a rainy day, and the misery 
of the bird (if it is miserable) consists in its perpetual, 
never-satisfied craving for food. 



WHITE AND SNOWY EGRETS loi 
WHITE EGRET AND SNOWY EGRET 

Ardea egretta : A. candidissima 

Entire plumage snow-white in both species. Length of White Egret 
35 inches ; length of Snowy Egret 24 inches. 

These two species are found in South, Central, and 
North America ; but the larger bird has a greater 
range, being found from Nova Scotia to Patagonia, 

The small Snowy Egret abounds most in the hot 
and warm regions, and is quite common on the 
pampas but rare in Patagonia, It is more gregarious 
and social in its habits than the White Egret and is 
usually seen in flocks and associates with Ibises, 
Spoonbills, and other aquatic birds. 

On the pampas, owing to the absence of forests, 
the nesting habits, like those of the Cocoi and other 
Herons, have been modified, for there it nests among 
the bulrushes and sedges. I take the following account 
of a heronry on the pampas from a paper by Mr, 
Ernest Gibson. He was so fortunate as to find both 
species breeding together in considerable numbers. 

** In November of 1873 I found a large breeding 
colony of Ardea egretta^ A. candidissima^ and Nycti- 
corax obscurus in the heart of a lonely swamp. The 
rushes were thick, but had been broken down by 
the birds in a patch some fifty yards in diameter. 
There were from 300 to 400 nests, as well as I could 
judge ; of these three-fourths were of A. egretta, and 
the remainder, with the exception of two or three 
dozen of iV. obscurus, belonged to A, candidissima. 



102 BIRDS OF LA PLATA 

Those of the first-mentioned species were slight 
platforms^ placed on the tops of broken rushes, at 
a height of from two to three feet above the water, 
and barely a yard apart ♦ 

** The nests of A, candidissima were built up from 
the water to the height of a foot or a foot and a half, 
with a hollow on the top for the eggs ; they were 
very compactly put together, of small dry twigs of a 
water-plant. A good many were distributed amongst 
those of A. egretta ; but the majority were close 
together, at one side of the colony, where the reeds 
were taller and less broken. 

'' The nests of iV. obscurus much resembled the 
latter in construction and material ; but very few 
were interspersed amongst those of the other species, 
being retired to the side opposite A. candidissima ^ 
on the borders of some channels of clear water ; 
there they were placed amongst the high reeds, and 
a few yards apart from each other. 

** The larger Egrets remained standing on their 
nests till I was within twenty yards of them, and 
alighted again when I had passed. In this position 
they looked much larger than when flying. The 
smaller Egrets first flew up on to the reeds, and then 
immediately took to flight, not returning ; while iV. 
obscurus rose and sailed away, uttering a deep squawk, 
squawk, long before one came near the nest. 

'' At one side of the colony a nest of Ciconia 
maguari, with two full-grown young, seemed like the 
reigning house of the place. 

** It certainly was one of the finest ornithological

Whistling Heron 

Ardea sibilatrix. Temm. 



WHISTLING HERON 103 

sights I ever saw : all around a wilderness of dark 
green rushes, rising above my head as I sat on horse- 
back ; the cloud of graceful snow-white birds 
perched everywhere, or reflected in the water as 
they flew to and fro overhead ; and the hundreds of 
blue eggs exposed to the bright sunlight* 

*' A, egretta and A, candidissima lay four eggs each, 
though the former rarely hatches out more than 
three* N. ohscurus lays and hatches out three. The 
eggs of all three species are of the same shade of 
light blue/' 



WHISTLING HERON 

Ardea sibilatrix 

Above grey ; cap, crest, and wings greyish black ; a rufous 
patch behind the eye ; upper wing-coverts rufous ; beneath white, 
with yellowish tinge on breast ; beak reddish. Length 22 inches. 
Female similar. 

This is a beautiful bird, with plumage as soft as 
down to the touch. Its colours are clear blue-grey 
and pale yellow, the under surface being nearly 
white. In some specimens that I have obtained the 
rump and tail-coverts had a pure primrose hue. 
There is a chestnut mark on the side of the head ; 
the eye is white, and the legs dark green in life, 

A^ara named this Heron Flauta del Sol (Flute of 
the Sun), a translation of the Indian term Curahi- 
remimhif derived from the popular belief that its 
whistling notes, which have a melodious and melan- 
choly sound, prophesy changes in the weather. 



104 BIRDS OF LA PLATA 

It comes as far south as Buenos Ayres, but is only 
a summer visitor there, and very scarce. Having 
seen but little of it myself, I can only repeat Azara^s 
words concerning it. He says it is common in Para- 
guay, going in pairs or families, and perches and 
roosts on trees, and when flying flaps its wings more 
rapidly than other Herons. It makes its nest on a 
tree, and lays two clear blue eggs. 

I saw less of the Whistling or '^Fluting" Heron than 
of aiiy of the seven species I was acquainted with in 
La Plata. About its habits I found out nothing, and 
on that account I should have omitted all mention 
of it — that being the rule in this book — if its strange 
beauty had not charmed and made a lasting impres- 
sion on my mind. The stuffed specimens, from 
which the description is taken, do not show the 
colours of the living bird — the soft clear grey and 
primrose yellow — most delicate colours and rarely 
seen in a bird of this size. In the museum specimens 
the primrose yellow fades to white with a dull 
yellowish tinge. 



LITTLE BLUE HERON 

Butorides cyanurus 

Above blue grey ; beneath ash-colour ; black crest with greenish 
gloss ; ferruginous spots on the neck ; length 14 inches. 

The Little Blue Heron, though widely distributed, 
is not anywhere a common bird. I have always 
seen it singly, for it loves a hermit-life, and the 



LITTLE RED HERON 105 

feeding-ground it prefers is a spot on the borders of 
a marshy stream shut in and overshadowed on all 
sides by trees and tall rushes. There the bird sits 
silent and solitary on a projecting root or dead 
branch ; or stands motionless and knee-deep in the 
water, intent on the small fry it feeds on. For whole 
months it will be found every day in the same place. 
When intruded on in its haunts it erects the feathers 
of its head and neck, looking strangely alarmed or 
angry, and flies away uttering a powerful, harsh, 
grating cry. 



LITTLE RED HERON 

Ardetta involucris 

Above light fulvous^ a black stripe on the nape ; front, stripe on 
back of the neck, bend of wing and outer secondaries, chestnut-red ; 
back striped with black ; wing-feathers ash-grey with red tips ; be- 
neath yellowish white striped with brown ; beak yellow, feet green ; 
length 13, wing 5 inches. 

The Little Red, or Variegated, Heron which inhabits 
Paraguay and Argentina, is the least of the family 
to which it belongs, its body being no bigger than 
that of the Common Snipe ; but in structure it is 
like other Herons, except that its legs are a trifle 
shorter in proportion to its size and its wings very 
much shorter than in other species. The under 
plumage is dull yellow in colour, while all the other 
parts are variegated with marks of fuscous and 
various shades of brown and yellow. The body is 



io6 BIRDS OF LA PLATA 

extremely slim, and the lower portion of the neck 
covered with thick plumage, giving that part a de- 
ceptively massive appearance. The perching faculty, 
possessed in so eminent a degree by all Herons, 
probably attains its greatest perfection in this species, 
and is combined with locomotion in a unique and 
wonderful manner. It inhabits beds of rushes grow- 
ing in rather deep water ; very seldom, and probably 
only accidentally, does it visit the shore, and only 
when driven up does it rise above the rushes ; for 
its flight, unlike that of its congeners, is extremely 
feeble. The rushes it lives amongst rise, smooth as 
polished pipe-stems, vertically from water too deep 
for the bird to wade in ; yet it goes up to the summit 
and down to the surface, moving freely and briskly 
about amongst them, or runs in a straight line 
through them almost as rapidly as a Plover can run 
over the bare level ground. Unless I myself had 
been a witness of this feat I could scarcely have 
credited it ; for how does it manage to grasp the 
smooth vertical stems quickly and firmly enough 
to progress so rapidly without ever slipping down 
through them $* 

The Variegated Heron is a silent, solitary bird, 
found everywhere in the marshes along the Plata, 
as also in the rush- and sedge-beds scattered over 
the pampas. It breeds amongst the rushes, and lays 
from three to five spherical eggs, of a rich lively 
green and beautiful beyond comparison. The nest 
is a slight platform structure about a foot above the 
water, and so small that there is barely space enough 



LITTLE RED HERON 107 

on it for the eggs^ which are large for the bird. When 
one looks down on them they cover and hide the 
slight nest, and being green like the surrounding 
rushes they are not easy to detect. 

When driven up the bird flies eighty or a hundred 
yards away, and drops again amongst the rushes ; 
it is difficult to flush it a second time, and a third 
time it is impossible. A curious circumstance is 
that where it finally settles it can never be found. 
As I could never succeed in getting specimens when 
I wanted them, I once employed some gaucho boys, 
who had dogs trained to hunt flappers, to try for 
this little Heron. They procured several specimens, 
and said that without the aid of their dogs they 
could never succeed in finding a bird, though they 
always marked the exact spot where it alighted. 
This I attributed to the slender figure it makes, and 
to the colour of the plumage so closely assimilating 
to that of the dead yellow and brown-spotted rushes 
always found amongst the green ones ; but I did 
not know for many years that the bird possessed a 
marvellous instinct that made its peculiar conforma- 
tion and imitative colour far more advantageous 
than they could be of themselves. 

One day in November when out shooting, I noticed 
a Variegated Heron stealing off quickly through a 
bed of bulrushes, thirty or forty yards from me ; 
he was a foot or so above the ground, and went so 
rapidly that he appeared to glide through the rushes 
without touching them. I fired, but afterwards 
ascertained that in my hurry I had missed my aim. 



io8 BIRDS OF LA PLATA 

The bird^ however, disappSred at the report ; and 
thinking I had killed him I went to the spot. 

It was a small, isolated bed of rushes I had seen 
him in ; the mud below and for some distance 
round was quite bare and hard, so that it would 
have been impossible for the bird to escape without 
being perceived ; and yet, dead or alive, he was not 
to be found. After vainly searching and re-searching 
through the rushes for a quarter of an hour I gave 
over the quest in great disgust and bewilderment, 
and, after reloading, was just turning to go, when 
behold ! there stood my Heron on a rush, no more 
than eight inches from, and on a level with, my 
knees. He was perched, the body erect, and the 
point of the tail touching the rush grasped by its 
feet ; the long slender tapering neck was held stiff, 
straight and vertically ; and the head and beak, 
instead of being carried obliquely, were also pointing 
up. There was not, from his feet to the tip of his 
beak, a perceptible curve or inequality, but the whole 
was the figure (the exact counterpart) of a straight 
tapering rush : the loose plumage arranged to fill 
inequalities, and the wings pressed into the hollow 
sides, made it impossible to see where the body 
ended and the neck began, or to distinguish head 
from neck or beak from head. This was, of course, 
a front view ; and the entire under surface of the 
bird was thus displayed, all of a uniform dull yellow, 
like that of a faded rush. I regarded the bird wonder- 
ingly for some time ; but not the least motion did 
it make. I thought it was wounded or paralysed with 



LITTLE RED HERON 109 

fear^ and, placing my hand on the point of its beak, 
forced the head down till it touched the back ; when 
I withdrew my hand up flew the head, like a steel 
spring, to its first position* I repeated the experiment 
many times with the same result, the very eyes of 
the bird appearing all the time rigid and unwinking 
like those of a creature in a fit. What wonder that 
it is so difficult, almost impossible, to discover the 
bird in such an attitude ! But how happened it that 
while repeatedly walking round the bird through 
the rushes I had not caught sight of the striped back 
and the broad dark-coloured sides $* I asked myself 
this question, and stepped round to get a side view, 
when, mirahile dictu, I could still see nothing but 
the rush-like front of the bird ! His motions on the 
perch, as he turned slowly or quickly round, still 
keeping the edge of the blade-like body before me, 
corresponded so exactly with my own that I almost 
doubted that I had moved at alL No sooner had I 
seen the finishing part of this marvellous instinct 
of self-preservation (this last act making the whole 
complete) than such a degree of delight and admiration 
possessed me as I have never before experienced 
during my researches, much as I have conversed with 
wild animals in the wilderness, and many and perfect 
as are the instances of adaptation I have witnessed, 
I could not finish admiring, and thought that never 
had anything so beautiful fallen in my way before ; 
for even the sublime cloud-seeking instinct of the 
White Egret and the typical Herons seemed less 
admirable than this ; and for some time I continued 



no BIRDS OF LA PLATA 

experimenting^ pressing d^n the bird*s head and 
trying to bend him by main force into some other 
position ; but the strange rigidity remained unre- 
laxed; the fixed attitude unchanged, I also found, 
as I walked round him, that as soon as I got to the 
opposite side and he could no longer twist himself on 
his perch, he whirled his body with great rapidity the 
other way, instantly presenting the same front as before. 
Finally I plucked him forcibly from the rush and 
perched him on my hand, upon which he flew away ; 
but he flew only fifty or sixty yards off, and dropped 
into the dry grass. Here he again put in practice 
the same instinct so ably that I groped about for 
ten or twelve minutes before refinding him, and was 
astonished that a creature to all appearance so weak 
and frail should have strength and endurance suffi- 
cient to keep its body rigid and in one attitude for 
so long a time. 

Some recent or at all events later observations 
appear to show that some species of Bittern possess 
a similar instinct to that of the bird described — the 
faculty of effacing themselves as it were in the presence 
of an enemy. Doubtless any Bittern, its colouring 
being what it is, would make itself invisible among 
partially decayed and dead vegetation by extending 
and stiffening its body and keeping its breast towards 
its intruder. The peculiar thing in the case of the 
small Heron is that the whole action of the bird 
appears to be framed and designed expressly to make 
it look exactly like a dead yellow tapering bulrush. 



LITTLE RED HERON iii 

But what can one say of such an instinct — if we 
can call it an instinct i It is in its essence a weakness 
in the creature similar to that of many mammals, 
birds, fishes, batrachians, reptiles and insects that 
become paralysed with fear, or rather hypnotised, 
in the presence of an enemy, A strange flaw in the 
animal, since it brings to naught all the admirable 
instincts of self-preservation it has been endowed 
with, and gives it, without a struggle, a prey to its 
enemies, even to those of a slow, sluggish disposition. 

In this particular instance the weakness or fault 
of nature has been taken advantage of by that principle 
which we call natural selection and has resulted in a 
more perfect protection than if the bird had been 
incapable of losing its mind, as one may say. In 
other words, the creature^s liability to the hypnotic 
or cataleptic state on certain occasions is its best 
protection. 

This, however, is not the only case in which a 
seemingly fatal weakness has been turned to good 
account, as we see in the death-like swoon, or '' pre- 
tending to be dead," of many creatures when over- 
come by or in the presence of an enemy. I have 
observed it in the pampas fox and opossum, in the 
Tinamu, the Partridge of South America, in our 
Corncrake, and other Rails, and I have captured 
small birds by giving them a sudden fright. 

By a strange chance I discovered that my Little 
Bittern was also subject to this weakness. A gaucho 
boy of my acquaintance, knowing that I was interested 
in this bird, one day brought me a dead specimen. 



112 BIRDS OF LA PLATA 

He said he had flushed it Trom a rush-bed, and as 
the bird flew away over dry land, he gave chase, and 
soon ran it down and captured it ; but though 
perfectly uninjured it quickly died in his hand. As 
it was too late in the evening for me to deal with it 
I put it in a cage which had once been used to keep 
a Cardinal Finch in and hung it up under the veranda 
where it would be safe from cats. Next morning 
to my very great astonishment it was gone ! A 
long-dead bird in a closed cage hung high up out of 
the way for safety, and now it was not there ! How 
explain such a thing ^ There was no possible ex- 
planation, and it made me perfectly miserable for 
days thinking of it. Then at last it dawned on my 
weary brain that my dead bird had been alive all the 
time, that life had at all events come back to it, and 
that by squeezing its thin body edgeways through 
the wire it made its escape. Yet the wires were 
close enough to keep a Cardinal in confinement ! 



NIGHT-HERON 

Nycticorax obscurus 

Above ashy ; front white ; head, neck, and scapulars greenish black ; 
long crest plumes white ; beneath pale ; length 36, wing 12 inches. 

In the Argentine Republic the Night-Heron lives 
in communities, and passes the hours of daylight 
perched inactive on large trees or in marshes on the 
rushes, and when disturbed by day they rise up with 



MAGUARI STORK 113 

heavy flappings and a loud qua-qua cry. At sunset 
they quit their retreat^ to ascend a stream or seek 
some distant feeding-ground, and travel with a slow 
flight, bird succeeding bird at long intervals, and 
uttering their far-sounding, hoarse, barking night-cry. 

Where the flock lives amongst the rushes, in places 
where there are no trees, the birds, by breaking down 
the rushes across each other, construct false nests or 
platforms to perch on. These platforms are placed 
close together, usually where the rushes are thickest, 
and serve the birds for an entire winter. 

The breeding habits of the Night-Heron have 
been described in the account of an Egrets' heronry. 



MAGUARI STORK 

Euxenura maguari 

Plumage white ; wings and upper tail-coverts black ; naked lores 
and feet red ; bill horn-colour ; length 40^ wing 20 inches. 

The Maguari Stork is a well-known bird on the 
pampas, breeding in the marshes, and also wading 
for its food in the shallow water ; but it is not nearly 
so aquatic in its habits as the Jabiru, and after the 
breeding-season is over it is seen everywhere on the 
dry plains. Here these birds prey on mice, snakes 
and toads, but also frequently visit the cultivated 
fields in quest of food. When mice or frogs are 
exceptionally abundant on the pampas, the Storks 



114 BIRDS OF LA PLATA 

often appear in large numoers, and at such times I 
have seen them congregating by hundreds in the 
evening beside the water ; but in the daytime they 
scatter over the feeding-ground^ where they are seen 
stalking along^ intent on their prey, with majestic 
crane-like strides. To rise they give three long jumps 
before committing themselves to the air, and like all 
heavy fliers make a loud noise with their wings. They 
are never seen to alight on trees, like the Jabirti, 
and are absolutely dumb, unless the clattering 
they make with the bill when angry can be called a 
language. 

The laying-time is about the middle of August, 
and the nest is built up amongst the rushes, rising 
about two feet above the surface of the water. The 
eggs are rather long, three or four in number, and 
of a chalky white. 

Mr. Gibson, of Buenos Ayres, furnishes the follow- 
ing lively account of a young Maguari : '' One, 
which I took on 5th October, was about the size of a 
domestic fowl, in down, and, with the exception of 
the white tail, entirely black. It soon became very 
tame, and used to wander all over the premises, 
looking for food, or watching any work that was 
going on. Rats were swallowed whole ; and the way 
it would gulp down a pound or two of raw meat 
would have horrified an English housekeeper. Snakes 
it seized by the nape of the neck, and passed them 
transversely through its bill by a succession of rapid 
and powerful nips, repeating the operation two or 
three times before being satisfied that life was totally 



MAGUARI STORK 115 

extinct. It used often to do the same thing with dry 
sticks (in order not to forget the way, I suppose) ; 
while on one occasion it swallowed a piece of hard 
cowhide, a foot long, and consequently could not 
bend its neck for twenty-four hours after — till the 
hide softened, in fact. The story also went that 
* Byles the lawyer ' (as he was called) mistook the 
tail of one of the pet lambs for a snake, and actually 
had it down his throat, but was ' brought up ' by the 
body of the lamb ! Byles inspired a wholesome 
respect in all the dogs and cats, but was very peace- 
able as a rule. One of our men had played some 
trick on him, however ; and the result was that 
Byles generally went for him on every possible 
occasion, his long legs covering the ground like 
those of an Ostrich, while he produced a demoniacal 
row with his bill. It was amusing to see his victim 
dodging him all over the place, or sometimes, in 
desperation, turning on him with a stick ; but Byles 
evaded every blow by jumping eight feet into the 
air, coming down on the other side of his enemy, 
and there repeating his war dance ; while he always 
threatened (though his threats were never fulfilled) 
to make personal and pointed remarks with his for- 
midable bill, 

'' Shortly after his capture feathers began to 
appear ; and the following is a description of the 
bird at the age of about two months : Tail-feathers 
white, remainder of plumage glossy green-black ; 
bill black ; legs and feet grey. Spots and patches of 
white began to appear on head, back, and wings ; 



I 



ii6 BIRDS OF LA PLATA 

these gradually extended^ until, by the end of May, 
the adult plumage was all acquired. Then my interest 
in Byles ceased, and latterly he strayed away to his 
native swamps/' 



WOOD-IBIS 

Tantalus loculator 

White ; greater wing-coverts and wing- and tail-feathers black with 
bronze reflections ; head and upper part of neck naked, dusky ; 
vertex covered with a horny place ; sides of head purplish ; feet slaty ; 
length 44, wing 17 inches. Female similar. 

Most people in the Plata region are familiar with 
this bird of the marshes, its lofty stork-like figure 
and white plumage making it a very conspicuous 
object. 

On the pampas it is not uncommon in summer 
and autumn, and goes in flocks of a dozen or twenty. 
The birds are usually seen standing motionless in 
groups or scattered about in spiritless attitudes, 
apparently do2;ing away the time. On the wing it 
appears to better advantage, having a singularly 
calm, stately flight ; on a warm, still day they are 
often seen soaring in circles far up in the sky. 

I have never heard of this bird nesting on the 
pampas, and am inclined to think that it only breeds 
in forest regions, and visits the marshes in the tree- 
less districts after the young have flown. 

Its habits in North America, where it is called 
the *' Wood- Ibis," are tolerably well known, and in 



WOOD-IBIS 117 

the ornithological works of that country it is described 
as ** a. hermit standing listless and alone on the 
topmost limb of some tall decayed cypress^ its neck 
drawn in upon its shoulders, and its enormous bill 
resting like a scythe upon its breast/' 

It there nests on tall trees, som.etimes in company 
with Egrets, and lays three white eggs. 

There are three species of Stork in Argentina, 
the two described and the famous Jabirti, Mycteria 
americana* 

This is a majestic bird, the largest of the American 
Storks ; it stands five feet high, and the wings have 
a spread of nearly eight feet. The entire plumage is 
pure white, the head and six inches of the neck 
covered with a naked black skin ; from the back 
part extend two scarlet bands, the skin being glossy 
and exceedingly loose, and runs narrowing down to 
the chest. When the bird is wounded or enraged 
this loose red skin is said to swell out like a bladder, 
changing to an intensely fiery scarlet hue. The 
name Jabiru is doubtless due to this circumstance, 
for A2;ara (who gives the Guarani name of the Stork 
as Aiaiai) says that the Indian word Yahiru signifies 
** blown out with the wind.'' 

The Jabiru is but rarely found near Buenos Ayres, 
but occurs more frequently in Misiones, and in other 
districts on the northern frontier of the Republic. 
It nests on high trees, as has been recorded by 
Brown,^ and is said to lay ** blue-green " eggs.

ii8 BIRDS OF LA PLATA 



WHITE-FACED IBIS 

Plegadis guarauna 

Head, neck, and upper surface purplish chestnut, with a white band 
round the base of the bill ; back with metallic reflections ; wings and 
tail green with bronze reflections ; band across wing-coverts chestnut ; 
length 22, wing 9 inches. 

This form of the well-known *' Glossy Ibis ** of 
Europe is one of our most abundant waterfowl on 
the pampas, and appears in spring in flocks ; but as 
their movements are somewhat irregular and many 
individuals remain with us through the winter, their 
migrations probably do not extend very far. In 
summer they are found beside every marsh and 
watercourse, briskly wading about in the shallow 
water and plunging their long curved beaks down- 
wards at every step. When taking wing they invari- 
ably utter a loud ha ha ha, resembling hearty human 
laughter, but somewhat nasal in sound. They 
frequently leave the marshy places and are seen 
scattered about the grassy plains, feeding like land- 
birds ; and on the pampas they often congregate 
about the carcase of a dead horse or cow, to feed 
on the larvae of the flesh-fly, in company with the 
Milvago and the Hooded Gull. 

Their flight is singularly graceful ; and during 
migration the flocks are seen to follow each other in 
rapid succession, each flock being usually composed 
of from fifty to a hundred individuals, sometimes of 



WHITE-FACED IBIS 119 

a much larger number. It is most interesting to 
watch them at such times, now soaring high in the 
air, displaying the deep chestnut hue of their breasts, 
then descending with a graceful curve towards the 
earth, as if to exhibit the dark metallic green and 
purple reflections of their upper plumage. The flock 
is meanwhile continually changing its form or dis- 
position, as if at the signal of a leader. One moment 
it spreads out in a long straight line ; suddenly the 
birds scatter in disorder, or throw themselves together 
like a cloud of Starlings ; as suddenly they re-form 
to continue their journey in the figure of a phalanx, 
half-moon, or triangle. The fanciful notion can 
scarcely fail to suggest itself to the spectator that 
the birds go through these unnecessary evolutions 
intelligently in order to attain a greater proficiency 
in them by practice, or, perhaps, merely to make a 
display of their aerial accomplishments. The Glossy 
Ibis has another remarkable habit when on the wing. 
At times the flock appears as if suddenly seized with 
fren2;y or panic, every bird rushing wildly away from 
its fellows, and descending with a violent dg-zag 
flight ; in a few moments the mad fit leaves them, 
they rise again, reassemble in the air, and resume 
their journey. 



120 BIRDS OF LA PLATA 

BLACK-FACED IBIS 

Theristicus caudatus 

Sides of throat and lores bare, skin black ; top of head and lower 
part of neck in front reddish chestnut ; neck white ; back and wings 
grey with green reflections ; tertials and outer webs of secondaries 
for two-thirds of their length white, remainder dark green ; primaries 
dark green ; rump light green, bronzed ; tail dark bronze green ; 
under parts black; length 33, wing 16.25 inches. 

This very fine Ibis^ called Mandurria 6 Curucdu by 
Azara and Vanduria de invierno (Winter Vanduria) in 
the vernacular, is one of the most interesting winter 
visitors from Patagonia to the pampas of Buenos 
Ayres* It is found in Chili, and has even been 
obtained as far north as Peru. On the east side of 
the continent it is most abundant (during the cold 
season) about latitude 37 deg. or 38 deg. Its summer 
home and breeding ground appears to be in the 
extreme south of the continent, its eggs having been 
obtained on the Straits of Magellan by Darwin, and 
later by Dr. Cunningham, who only says of it 
that it is a shy and wary bird, that goes in flocks of 
from four to eight, and has a cry resembling qua-qua^ 
qua-qua. But he might just as well have spelt it 
quack-quack, since qua-qua fails to give the faintest 
idea of the series of hard, abrupt notes of extra- 
ordinary power the bird utters, usually when on the 
wing, which sound like blows of a powerful hammer 
on a metal plate. On the pampas this Ibis appears 
in May, frequents dry grassy situations, and goes 
in flocks of a do:^en to forty or fifty individuals.

Black- Faced Ibis 

Thfrt'sticus caiitiatus (Bodd.) 



BLACK-FACED IBIS 121 

They walk rapidly, stooping very much, and probing 
the ground with their long, slender, curved beaks, 
and appear to subsist principally on the larvae of the 
large horned beetle, with which their stomachs are 
usually found filled. So intent are they on seeking 
their food that the members of a flock often scatter 
in all directions and wander quite out of sight of 
each other ; when this happens they occasionally 
utter loud vehement cries, as if to call their com- 
panions, or to inform each other of their whereabouts. 
Frequently one is seen to lift up its wings as if to 
fly, and, stretching them up vertically, to remain 
for fifteen or twenty seconds in this curious attitude. 
At sunset they all rise up clamouring and direct their 
flight to the nearest watercourse, and often on their 
way thither go through a strange and interesting 
performance. The flock suddenly precipitates itself 
downwards with a violence wonderful to see, each 
bird rushing this way and that as if striving to outvie 
its fellows in every wild fantastic motion of which 
they are capable. In this manner they rise and 
descend again and again, sometimes massed together, 
then scattering wide apart in all directions. This 
exercise they keep up for some time, and while it 
lasts they make the air resound for miles with their 
loud percussive screams. 

In Patagonia I first observed this Ibis roosting 
on tall trees ; and, according to Azara, it possesses 
the same habit in Paraguay. He says that all the 
flocks within a circuit of some leagues resort to one 
spot to sleep, and prefer tall dead trees, bordering 



123 BIRDS OF LA PLATA 

on the water, and if therms only one suitable tree 
all the birds crowd on to it, and in the morning 
scatter, each family or pair flying away to spend the 
day in its customary feeding-ground. 

The egg obtained by Dr. Cunningham at Elizabeth 
Island is thus described by Prof. Newton {Ibis, 1870, 
p. 502) : '' Dull surface of a pale greenish white 
with engrained blotches (mostly small) of neutral 
tint, and some few blotches, spots, and specks of 
dull deep brown ; towards the larger end some hair- 
like streaks of a lighter shade of the same, and so 
far having an Ibidine or Plataleine character.** 



BLUE IBIS 

Harpiprion cierulescens 

White forehead joined to white bar above and behind the eye ; top 
of head and crest dark brown, with greenish tinge ; throat and neck 
covered with long narrow feathers, light brown with pinkish tinge in 
certain lights ; upper parts bluish bronzy green ; wings like the back, 
in some lights the feathers have a silvery gloss ; primaries dark blue ; 
tail dark green ; under parts brownish grey, with pink reflections in 
some lights ; length 33, wing 15.5 inches. 

This noble Ibis ranges from Brazil, south of the 
Amazons, to the pampas of Buenos Ayres. It is a 
bird of the marshes, nowhere abundant, and yet is 
exceedingly well known to most people in the Argen- 
tine country : it would be difficult indeed to overlook 
a species possessing so peculiar and powerful a 
voice. In the vernacular it is called Vanduria, with 



BLUE IBIS 123 

the addition of aplomado^ or barroso^ or de las lagunas, 
to distinguish it from the Winter Vanduria, The 
word is also frequently spelt Manduria or Banduriat 
but it does not come from handada (flock) ^ as Mr, 
Barrows imagines when he gives this vernacular name 
to the Glossy Ibis, but from the Spanish stringed 
instrument called vanduria. Possibly the instrument 
is obsolete now ; not so the word, however, and it 
is sometimes used by the poets, instead of '' harp ** 
or ** lyre " to symbolise poetic inspiration, especially 
in mock heroic compositions. Thus Iriarte : 

Atencion ! que la vanduria he templado. 

If one could get a banjo with brass strings so big 
that it could be heard a mile and a half away, a dozen 
strokes dealt in swift succession on one string would 
produce a sound resembling the call of this Ibis — 
a voice of the desolate marshes, which competes in 
power with the outrageous human-like shrieks of 
the Ypecaha Rail, the long resounding wails of the 
Cra2;y Widow or Courlan, and the morning song of 
the Crested Screamer. 

The Vanduria is usually seen singly or in pairs, 
and sometimes, but rarely, in small companies of 
half a dozen birds. In its habits it is like a Tantalus, 
wading in the shallow water of the marshes, and 
devouring eels, frogs, fish, etc. After examining the 
well-filled stomachs of a few individuals one is 
strongly tempted to believe that the beautiful long 
beak of this Ibis has '' forgotten its cunning *^ as a 
probe. At intervals in the daytime it utters, standing 



124 BIRDS OF LA PLATA 

on the ground, its resonant^etallic cry. It is wary 
and has a strong, easy flight, and is a great wanderer, 
but I am not able to say whether it possesses a regular 
migration or not. 

The celebrated naturalist Natterer procured speci- 
mens of this Ibis in the lagoons of Caicara, in the 
Brazilian province of Matogrosso, in September and 
November, 1825, t>ut it is not mentioned by general 
writers on the birds of South-east Bradl. 



WHISPERING IBIS 

Phimosus infuscatus 

Dark bronzy green, glossed with purple ; fore-part and sides of head 
and neck naked, red; bill and feet red; length 24, wing 11.5 inches. 

Of this Ibis, which ranges from Colombia to the 
Argentine Republic, a few individuals come as far 
south as the pampas of Buenos Ayres. 

The unfeathered state of the fore part of the head 
and throat suggested to A^ara the name of AfeytadOf 
or ** shaved," but about its habits he has nothing 
to say, nor dees he mention its peculiar voice, or, 
perhaps it would be more correct to say, its want of 
voice ; for it seems quite silent unless one comes 
near to it and listens very intently, when he will 
be able to hear little sigh-like puffs of sound as 
the bird flies away. It seems strange that this 
member of a loquacious loud-voiced family should 
be reduced to speak as it were in whispers ! 



ROSEATE SPOONBILL 125 

On two or three occasions I have seen as many as 
half a dozen individuals together ; at other times I 
have seen one or two associating with the Glossy 
Ibis. 

A2;ara's name, ** Shaved ** Ibis, seems well enough 
in Spanish, just as his '' Throat-cut '' for a Starling 
with a scarlet throat does not strike one as at all 
shocking in that language ; but for an English name 
I fancy that '* Whispering Ibis/* from the whisper- 
like sound the bird emits, would be more suitable, 
or at all events better sounding. 

It is possible that two races of this Ibis exist on 
the South American continent ; for in Bra2;il and 
further north it is said to have a loud cry, uttered 
when taking wing, as in the case of the Glossy Ibis ; 
and one of its native names in the tropics — curri- 
curri — is said to be an imitation of its usual note. 



ROSEATE SPOONBILL 

Ajaja rosea 

Head bare ; neck, back, and breast white ; tail orange-buff with 
the shafts deep pink ; rest of plumage pale rose-pink ; lesser wing- 
coverts and upper tail-coverts intense carmine ; neck with a tuft of 
twisted plumes, light carmine ; head greenish, space round the eye 
and gular sac orange ; eyes crimson, feet red ; length 30, wing 15 
inches. Female similar. Young with head completely feathered. 

The Roseate Spoonbill is found in both Americas 
and ranges south to the Straits of Magellan, but in 
Patagonia it is, I think, rare, for on the Rio Negro I 



126 BIRDS OF LA PLATA 

did not meet with it. On tfff pampas it is abundant, 
and I have been told that it breeds in the marshes 
there, but I have never been able to find a nest. It 
is usually seen in small flocks of from half a do^en 
to twenty individuals, which all feed near together, 
wading up to their knees and sweeping their long 
flat beaks from side to side as they advance. An 
English acquaintance of mine kept one of these birds 
as a pet on his estancia for seven years. It was very 
docile, and would spend the day roaming about the 
grounds, associating with the poultry, but invariably 
presented itself in the dining-room at meal-time, 
where it would take its station at one end of the 
table and dexterously catch in its beak any morsel 
thrown to it. 

Formerly, when I wrote the bird biographies for 
Argentine Ornithology I believed that there were 
two species of Spoonbill in Argentina, but I found 
that I was alone among ornithologists in that belief. 
I can, therefore, only repeat here a part of what I 
wrote in that work, and leave the question for time 
to decide. 

The general belief is that the pale-plumaged birds, 
with feathered heads and black eyes (the Roseate 
Spoonbill having crimson eyes), and without the 
bright wing-spots, the tuft on the breast, horny 
excresences on the beak, and other marks, are only 
immature birds. Now, for one bird with all these 
characteristic marks of the true Platalea ajaja, which 
has a yellow tail, we meet on the pampas with not 
less than a hundred examples of the pale-plumaged 



ARGENTINE FLAMINGO 127 

bird without any traces of such marks and with a 
rose-coloured tail ; and the disparity in number 
between mature and immature birds of one species 
could not well be so great as that* I have shot one 
immature specimen of the true Ajaja — so immature 
that it seemed not long out of the nest ; but the head 
was bare of feathers, and it had the knobs on the 
upper mandible, only they were so soft that they 
could be indented with the nail of the finger. Azara 
also mentions an immature bird which he obtained, 
but he does not say that the head was feathered ; 
and even this negative evidence goes a great way, 
since it would have been very unlike him to see a 
Spoonbill with a feathered head and otherwise unlike 
Ajaja rosea, and not describe it as a distinct species. 
To conclude, I may mention that the pet bird my 
friend kept was of the pale-plumaged species, and 
never lost the feathers from its head, nor did it, in 
seven years, acquire any of the characteristic marks 
of P. ajaja. 



ARGENTINE FLAMINGO 

Phcenicopterus ignipalUatus 

Plumage rosy red ; wing-coverts crimson ; wing-feathers black ; 
bill pale red, apical half black ; length 39, wing 15 inches. Female 
similar but smaller. 

The Argentine Flamingo inhabits the whole of the 
Argentine country, down to the Rio Negro in the 
south, where I found it very abundant. The resi- 
dents told me of a breeding-place there — a shallow 



128 BIRDS OF LA PLATA 

salt-lake — which^ however^^ad been abandoned by 
the birds before my visit. The nest there^ as in other 
regions^ was a small pillar of mud raised a foot or 
eighteen inches above the surface of the water^ and 
with a slight hollow on the top ; and I was assured 
by people who had watched them on their nests that 
the incubating bird invariably sits with the hind 
part of the body projecting from the nest, and the 
long legs dangling down in the water, and not tucked 
up under the bird. 

On the Rio Negro I found the birds most abundant 
in winter, which surprised me, for that there is a 
movement of Flamingoes to the north in the autumn 
I am quite sure, having often seen them passing 
overhead in a northerly direction in the migrating 
season. I have also found the young birds, in the 
grey plumage, at this season in the marshes near to 
Buenos Ayres city, hundreds of miles from any 
known breeding-place. Probably the birds in the 
interior of the country, where the cold is far more 
intense than on the sea-coast, go north before winter, 
while those in the district bordering on the Atlantic 
have become stationary. 

The Flamingo has a curious way of feeding : it 
immerses the beak, and by means of a rapid con- 
tinuous movement of the mandibles passes a current 
of water through the mouth, where the minutest 
insects and particles of floating matter are arrested 
by the teeth. The stomach is small, and is usually

stuff, mixed with minute particles of quartz. Yet 



ARGENTINE FLAMINGO 129 

on so scanty a fare this large bird not only supports 
itself but becomes excessively fat* I spent half a 
winter in Patagonia at a house built on the borders 
of a small lake, and regularly every night a small 
flock of Flamingoes came to feed in the water about 
200 yards from the back of the house, I used to open 
the window to listen to them, and the noise made 
by their beaks was continuous and resembled the 
sound produced by wringing out a wet cloth. They 
feed a great deal by day, but much more, I think, by 
night. 

Where they are never persecuted they are tame 
birds, and when a flock is fired into and one bird 
killed, the other birds, though apparently much 
astonished, do not fly away. They are silent birds, 
but not actually dumb, having a low, hoarse cry, 
uttered sometimes at the moment of taking flight ; 
also another cry which I have only heard from a 
wounded bird, resembling the gobbling of a turkey- 
cock, only shriller. They are almost invariably seen 
standing in the water, even when not feeding, and 
even seem to sleep there ; on land they have a very 
singular appearance, their immense height, in pro- 
portion to their bulk, giving them an appearance 
amongst birds something like that of the giraffe 
amongst mammals. To the lakes and water-courses 
in the midst of the grey scenery of Patagonia they 
seem to give a strange glory, while standing motion- 
less, their tall rose-coloured forms mirrored in the 
dark water, but chiefly when they rise in a long 
crimson train or phalanx, flying low over the surface,

130 BIRDS OF LA PLATA 



CRESTED SCREAMER 

Chauna chavaria 

Slatey grey, darker on the back ; chin, neck, and cheeks whitish ; a 
naked ring round the neck ; nape crested ; belly pale grey ; feet red ; 
length 32, wing 19 inches. 

This majestic bird^ called Chaja in the vernacular, 
is common throughout the Plata district, in marshes 
and on the open level country abounding in water 
and succulent grasses, and ranges south to the neigh- 
bourhood of Bahia Blanca. It is most abundant on 
the pampas south of Buenos Ayres city, and on that 
vast expanse of perfectly level green country the 
bird is seen at its best ; it is there an important 
feature in the landscape ; its vocal performances 
are doubly impressive on account of the profound 
silence of nature, and its singularity — the contrast 
between its aerial habit and ponderous structure — 
strikes one more forcibly where the view is so un- 
obstructed and the atmosphere so pure. 

The Crested Screamer, like most of the larger 
birds and mammals in every part of the globe to 
which European emigration is attracted, is probably 
doomed to rapid extermination. My observations 
of the bird, in that portion of the pampas where it 
is most abundant, date back some years, to a time 
when the inhabitants were few and mainly of Spanish 
race, never the destroyers of bird-life. The conditions 
had become extremely favourable to this species. 



CRESTED SCREAMER 131 

It is partially aquatic in its habits ; and in desert 
places is usually found in marshes^ wading in the 
shallow water, and occasionally swimming to feed 
on the seeds and J succulent leaves of water-loving 
plants. After the old giant grasses of the pampas 
had been eaten up by the cattle, and the sweet grasses 
of Europe had taken their place, the Screamers took 
kindly to that new food, preferring the clovers, and 
Seemed as terrestrial in their feeding-habits as Up- 
land Geese. Their food was abundant, and they 
were never persecuted by the natives. Their flesh 
is very dark, is coarse-grained but good to eat, with 
a flavour resembling that of Wild Duck, and there 
is a great deal of meat on a bird with a body larger 
than that of a Swan. Yet no person ever thought 
of killing or eating the Chaja ; and the birds were 
permitted to increase to a marvellous extent. It was 
a common thing a few years ago in the dry season 
to see them congregated in thousands ; and so little 
afraid of man were they that I have often ridden 
through large scattered flocks without making the 
birds take wing. 

A curious thing about the Screamer is that it pairs 
for life, and yet is one of the most social of birds. 
But if a large flock is closely looked at, the birds are 
invariably seen methodically ranged in pairs. Another 
curious thing is that, notwithstanding the formidable 
weapons they possess (each wing being armed with 
two large spurs), they are extremely pacific in temper. 
I have never been able to detect even the slightest 
approach to a quarrel among them ; yet it is hard 



132 BIRDS OF LA PLATA 

to believe that they do not fight sometimes, since 
weapons of offence are usually found correlated with 
the disposition to use them. Captive birds, however, 
can be made to fight ; and I have known gauchos 
take them for the pleasure of witnessing their battles. 
They are very easily tamed, and in that state seem 
to show greater docility and intelligence than any 
of our domestic birds ; and become so attached to 
their home that it is quite safe to allow them to fly 
about at will. They associate, but do not quarrel, 
with the poultry. They are quick to distinguish 
strangers from the people of the house, showing 
considerable suspicion of them, and sometimes rais- 
ing a loud alarm at a stranger's approach. Towards 
dogs and cats they are often unfriendly ; and when 
they are breeding it is dangerous for a strange person 
to approach the nest, as they will sometimes attack 
him with the greatest fury. 

The Screamer is a very heavy bird, and rises from 
the ground laboriously, the wings, as in the case of 
the Swan, making a loud noise. Nevertheless it loves 
soaring, and will rise in an immense spiral until it 
wholly disappears from sight in the zenith, even in 
the brightest weather ; and considering its great 
bulk and dark colour, the height it ultimately attains 
must be very great. On sunny, windless days, es- 
pecially in winter and spring, they often spend hours 
at a time in these sublime aerial exercises, slowly 
floating round and round in vast circles, and singing 
at intervals. How so heavy and comparatively short- 
winged a bird can sustain itself for such long periods 



CRESTED SCREAMER 133 

in the thin upper air to which it rises has not yet 
been explained ♦ 

The voice is very powerful. When disturbed, or 
when the nest is approached, both birds utter at 
intervals a loud alarm-cry, resembling in sound the 
anger-cry of the Peacock, but twice as loud. At other 
times its voice is exercised in a kind of singing per- 
formance, in which male and female join, and which 
produces the effect of harmony. The male begins, 
the female takes up her part, and then with mar- 
vellous strength and spirit they pour forth a torrent 
of strangely-contrasted sounds — some bassoon-like 
in their depth and volume, some like drum-beats, 
and others long, clear, and ringing. It is the loudest 
animal-sound of the pampas, and its jubilant, martial 
character strongly affects the mind in that silent, 
melancholy wilderness. 

The Screamers sing all the year round, at all hours, 
both on the ground and when soaring ; when in 
pairs the two birds invariably sing together, and 
when in flocks they sing in concert. At night they 
are heard about nine o'clock in the evening, and again 
just before dawn. It is not unusual, however, to 
hear them singing at other hours. 

The nest is a large fabric placed among the low 
rushes and water-lilies, and is sometimes seen float- 
ing on the water, away from its moorings. The eggs 
are five, pointed at one end, pure white, and in size 
like the eggs of the domestic Goose. The young are 
clothed in yellow down like goslings, and follow the 
parents about from the date of hatching. 



134 BIRDS OF LA PLATA 

BARRED UPLAND GOOSE 

Bernicla dispar 

White ; neck behind and body beneath banded with black ; primaries, 
greater wing-coverts, tertiaries, and scapulars cinereous ; rump and 
tail-feathers ashy black ; bill black, feet plumbeous ; length 26, 
wing 16 inches. Female, head and neck cinnamon-brown ; abdomen 
similar, barred with black ; upper part also barred ; rump and tail- 
feathers brownish black. 

This bird is a northern form of the well-known 
** Upland Goose " of the Falkland Isles and Southern 
Patagonia, from which it differs in the male being 
completely barred across with black on the lower 
surface. It was first described by Philippi and Land- 
beck from Chilian specimens, and in 1872 was 
recognised by Dr. Burmeister as found near the 
Sierra Tandil and on the Rio Negro. 

In April and May this Goose migrates north- 
wards, along the eastern coast, as far as the pampas 
of Buenos Ayres, the migration ending about one 
hundred and fifty miles south of Buenos Ayres city. 
Further south they are at this season of the year 
excessively abundant in suitable localities. Their 
great camping-grounds are the valleys of the rivers 
Negro and Colorado, where they are often so numer- 
ous as to denude the low grounds of the tender 
winter clovers and grasses, and to cause serious loss 
to the sheep-breeders. They also visit the cultivated 
fields to devour the young wheat, and are intelligent 
enough to distinguish between a real human enemy 
and the ragged men of straw, miscalled scarecrows. 



ASHY-HEADED UPLAND GOOSE 135 

set up by the farmers to frighten them. While com- 
mitting their depredations they are exceedingly wary 
and difficult to shoot, but at night, when they con- 
gregate by the water-side, they give the sportsman 
a better chance, I have succeeded in killing as many 
as five at a shot by stalking them under cover of the 
darkness ; arid a more deliciously-flavoured game- 
bird than this Goose I have never tasted. 

They are social birds, always going in large flocks, 
and are very loquacious, the female having a deep 
honking note, while the male responds with a clear 
whistling, like the Sanderling*s note etherealised. 



ASHY-HEADED UPLAND GOOSE 

Bemicla poliocephala 

Head, neck, and scapulars leaden grey ; breast and upper back chest- 
nut, banded with black ; abdomen, under wing-coverts, and bend of 
the wing white ; primaries black ; secondaries white ; greater wing- 
coverts black, edged with green and tipped with white ; lower back 
and tail black ; bill black, feet yellow ; length 24, wing 13.5 inches. 
Female similar. 

This Patagonian Goose migrates northwards in 
winter, and appears on the Rio Negro and in the 
Buenos-Ayrean pampas in May, usually in small 
flocks, but sometimes as many as one or two hundred 
are seen together. The extreme limit of their winter 
migration appears to be about sixty miles south of 
Buenos Ayres city, on the plains near the river 



136 BIRDS OF LA PLATA 

Sanborombon ; probably tl^ have before now been 
driven from this locality by the duck-shooters, but 
it was formerly their favourite rendezvous, where 
they collected in large numbers, though further 
north scarcely one was ever seen. 

Durnford tells us that this Goose is resident on 
Lake Colguape in the territory of Chupat, and breeds 
there abundantly. 



BLACK-NECKED SWAN 

Cygnus nigricollis 

White ; head and neck black ; postocular stripe and chin white ; 
lores naked ; bill plumbeous, cere red. Length 48, wing 17 inches. 
Female similar. 

To my perhaps partial mind this species is pre- 
eminent for beauty among the Swans, although it 
is considerably smaller than the bird of the Old 
World, and does not, it must be admitted, comport 
itself so majestically* In questions of this kind it 
is natural for every one to be somewhat biassed in 
favour of the things of his own country ; but it will 
be readily admitted by all, I think, that the black- 
necked bird is one of three species greatly surpassing 
all others of this genus in beauty — the other two 
being, of course, the domesticated Swan of Europe 
and the Australian Black Swan (the most graceful 
of Swans). 

This Swan is very abundant on the pampas of 



BLACK-NECKED SWAN 137 

Buenos Ayres and in Patagonia^ and ranges south 
to the Magellan Straits and the Falklands. As a rule 
they are seen in small flocks, but sometimes as many 
as two or three hundred congregate together. They 
are heavy birds and rise with difficulty, and fly 
rapidly and with great violence, like all heavy-bodied 
short-winged species ; but in no other very large 
bird with which I am acquainted do the wings 
produce so loud a rushing sound. In quiet places 
the beating of their wings can be heard distinctly 
when the birds are no longer in sight, although, 
owing to their large size, the eye can follow them 
very far. Gauchos sometimes capture them by 
suddenly charging down the wind upon them, 
uttering loud shouts which greatly terrify the birds, 
and when they attempt to rise with the wind they 
only flap along the ground and are easily knocked 
over. A gaucho of my acquaintance one day caught 
three out of a flock of six in this way ; but a very 
strong wind favoured him, and the birds were at 
some distance from the water, and allowed him to 
come near before making the sudden charge. 

According to Mr. Gibson, who has observed their 
breeding-habits, they begin to nest in July — just 
after the winter solstice. The nest is always placed 
among thick rushes growing in deep water, and the 
Swan invariably swims to and from her nest. It is 
built up from the bottom of the swamp, in some 
instances four or five feet deep, and rises a foot 
and a half above the surface. The top of the nest 
measures about two feet across, with a slight hollow 



138 BIRDS OF LA PLATA 

for the eggs, which are ciiRm-coloured and have a 
smooth glossy shell. The number varies from three 
to five, and on one occasion six were found. Mr, 
Gibson has seen the parent bird swimming from the 
nest with the young on her back. 



COSCOROBA SWAN 

Coscoroba Candida 

White ; tips of primaries black ; bill coral red^ feet red ; length 
40, wing 17.5 inches. 

This Swan is considerably smaller than the black- 
necked species, and also inferior in beauty on account 
of its shorter neck. It is, nevertheless, a very hand- 
some bird, being entirely of a pure white colour 
except the tips of the primaries, which are black. 
The beak and legs are bright rosy red. In its habits, 
language, and flight it also differs much from Cygnus 
nigricoUis, and the country people call it Ganso 
(Goose), probably on account of its Goose-like habit 
of sometimes feeding away from the water, or 
because its flesh has the flavour of Wild Goose. 
Oddly enough, the scientific ornithologists are just 
beginning to find out that the common people were 
right in describing it as a Goose ; at all events they 
are finding out that it has more Goose than Swan in 
its composition. As a rule they go in small parties 
of five or six individuals, but sometimes flocks num- 



FULVOUS TREE-DUCK 139 

bering two or three hundred are seen in the cold 
season* Their migrations are very irregular^ and 
sometimes they are excessively abundant in a district 
one year and absent from it the next. When disturbed 
they utter a loud musical trumpeting cry, in three 
notes, the last with a falling inflexion ; and their 
wings being much longer proportionately than in 
the black-necked species, they rise with greater ease 
and have a much freer and an almost soundless 
flight. 

Concerning their breeding-habits Mr. Gibson 
observes that the nest is usually placed on the 
ground at some distance from the water. It is 
about a foot and a half high, made of mud and 
rushes ; the hollow, which is rather deep, is lined 
with dry grass. 

The eggs are eight or nine in number ; smooth, 
white, and rounder than those of Cygnus nigricollis. 



FULVOUS TREE-DUCK 

Dendrocygna fulva 

Chestnut-red, top of head darker, with black line down the nape ; 
back black on the upper portion, banded with chestnut ; wings and 
tail black ; lesser wing-coverts dark chestnut ; upper tail-coverts 
white ; flanks chestnut, banded with black and white ; bill and feet 
black ; length i8, wing 8.5 inches. 

This Duck, the well-known Pato silvon (Whistling 
Duck) of the eastern Argentine country, is found 
abundantly along the Plata and the great streams 



140 BIRDS OF LA PLATA 

flowing into it, and northwaits to Paraguay, Along 
this great waterway it is to some extent a migratory 
specieS; appearing in spring in Buenos Ayres in very 
large numbers, to breed in the littoral marshes and 
also on the pampas. They migrate principally by 
night, and do not fly in long trains and phalanxes 
like other Ducks, but in a cloud ; and when they 
migrate in spring and autumn the shrill confused 
clangour of their many voices is heard from the 
darkness overhead by dwellers in the Argentine 
capital ; for the Ducks, following the eastern shore 
of the sea-like river, pass over that city on their 
journey. Northwards this Duck extends to Central 
Brazil ; from the northern half of the southern 
continent and from Central America it is absent ; 
but it re-appears in Mexico. Commenting on these 
facts Messrs. Sclater and Salvin write : ** Singular 
as this distribution is, it is still more remarkable 
when we consider that there appear to exist no 
tangible grounds for separating the American bird 
from that called Z). major by Jerdon, which ranges 
throughout the peninsula of India and is also found 
in Madagascar ! '' 

The Whistling Duck, in its chestnut and fulvous 
plumage, is a handsome bird and somewhat singular 
in appearance, especially when seen in a large body 
on the ground. When out of the water they crowd 
close together, and when disturbed stand up craning 
their necks, looking strangely tall on their long blue 
legs. While thus watching an intruder they are 
silent, and the sudden ringing chorus of whistling 



WHITE-FACED TREE-DUCK 141 

voices into which they burst at the moment of rising 
has a curious effect. 

So extremely social are these Ducks that even when 
breeding they keep together in large flocks. The 
nest is made of stems and leaves, on the water among 
the reeds and aquatic plants ; and sometimes large 
numbers of nests are found close together, as in a 
guUery. The eggs are pure white, and each bird 
lays, I believe, ten or twelve, but I am not sure about 
the exact number ; and I have so frequently found 
from twenty to thirty eggs in a nest that I am con- 
vinced it is a not uncommon thing for two or three 
females to occupy one nest. 



WHITE-FACED TREE-DUCK 

Dendrocygna viduata 

Face and spot on throat white ; nape, neck in front, middle of 
abdomen, tail, rump, and wings black ; hind neck chestnut ; middle 
of back and scapulars brown, feathers with fulvous margins ; wing- 
coverts olive-black ; flanks banded with black and white ; bill and 
feet black ; length 17, wing 9 inches. Female similar. 

This Tree-Duck resembles that last described in 
size, form, and maroon-red plumage, but is of a 
darker tint, and may also be easily distinguished, 
even at a long distance, by its white face contrasted 
with the velvety black of the head and neck. One 
of its vernacular names is Pato viuda (Widow Duck) 



142 BIRDS OF LA PLATA 

from its dark plumage reli^Ptd by white in front. 
Compared with Dendrocygna fulva it is a rare species, 
and goes always with its mate, but I have seen as 
many as half a dozen together. When taking wing 
it also whistles, but differently from the allied species, 
having three long clear whistling notes, not unlike 
the three-syllabled cry of the Sandpiper, only the 
notes are more prolonged. Of its breeding habits 
I know nothing. 



BLUE-WINGED TEAL 

Querquedula cyanoptera 

Plumage red ; crown black ; lesser wing-coverts blue ; wing 
speculum green, margined above with white ; wing feathers black ; 
bill black, eyes golden, feet orange ; length i8 ; wing 7.6 inches. 
Female ; blackish above, feathers margined with whitish ; beneath 
dull white variegated with brown ; throat white with black freckles. 

This Teal has an exceedingly wide distribution in 
America, being found from California in the northern 
continent down to the Straits of Magellan and the 
Falkland Islands in the south. Its fine, strongly 
contrasted colours give it a very handsome appear- 
ance — the wings being clear grey-blue, the body deep 
maroon-red, the feet vivid yellow, beak black, and 
iris gold-colour. On the pampas it is common, and 
almost invariably seen in pairs at all seasons. Many 
of the Teals are quarrelsome in disposition ; but 



YELLOW-BILLED TEAL 143 

this species, I think, exceeds them all in pugnacity, 
and when two pairs come together the males almost 
invariably begin fighting. 



YELLOW-BILLED TEAL 

Querquedula flavirostris 

Above slatcy brown ; head barred with narrow blackish bands ; 
middle of back rufescent^ with centres of the feathers black and 
narrowly margined with ochraceous ; a broad wing speculum, black, 
margined with ochraceous above and below and a bronzy green 
blotch in the centre ; wing feathers slatey ; margins of secondaries 
pale rufous ; beneath whitish, spotted with black ; bill yellow, feet 
dark ; length 15, wing 7.5 inches. Female similar. 

In the southern part of the Argentine Republic this 
is one of the commonest species, and is almost invari- 
ably found in every marsh, stream, and pool of water 
on the pampas ♦ It is resident, and usually goes in 
flocks of from a dozen to thirty individuals. It has 
a rapid flight, and is restless, lively, and extremely 
pugnacious in its habits. When a flock is on the water 
the birds are perpetually quarrelling. They are also 
highly inquisitive, and I have often shot them by 
first showing myself to the flock, and then standing 
or sitting still, when they would soon come wheeling 
about, flying in very close order. They quack and 
chatter in a variety of tones, and the male has also a 
clear, whistling note in the love-season. 

The nest of this Duck is always made at a distance 
from the water, sometimes as far as one or two miles. 



144 BIRDS OF LA PLATA 

It consists of a slight holl^ in the ground under a 
thistle-bush or tussock of long grass, and is lined with 
dry grass and a great deal of down, which is increased 
in quantity during incubation. The eggs are reddish 
cream-colour, and five is the usual number laid ; but 
I have also found nests with six and seven. 



GREY TEAL 

Querquedula versicolor 

Above grey with narrow black cross-bands ; top of head blackish 
brown, sides of head and throat white ; beneath whitish, tinged 
with ochraceous and spotted with black on the breast ; wings greyish 
brown, speculum purplish green, margined with white above and 
below and a subterminal black band ; flanks barred with black and 
white ; bill black with an orange patch on each side at the base of 
the mandible ; feet dark ; length 16.5, wing 7.6 inches. Female 
similar but colours less bright. 

This prettily variegated blue-grey Teal with its 
strongly-marked black and orange bill is perhaps the 
most abundant of the genus in the Argentine Re- 
public, especially in the southern portion. It is 
resident, and unites in much larger flocks than any 
other bird of this group in the country. Its note 
when disturbed or flying is very peculiar, resembling 
in sound the muffled stridulating of the mole-cricket. 



RING-NECKED TEAL 145 



RING-NECKED TEAL 

Querguedula torquata 

Above dull brown ; head above and neck, expanding to a half 
collar, also lesser wing-coverts, lower back, and tail, black ; scapulars 
pure chestnut; wings brownish black, with a large white patch on 
coverts of the bronze-green secondaries ; beneath, sides of head and 
throat dull white, streaked with brown ; breast tinged with rosy red, 
sparingly spotted with black ; belly and flanks white, narrowly barred 
with grey; length 14, wing 7.2 inches. Female brown ; superciliaries, 
stripe on each side of head, throat, and sides of neck, white ; beneath 
white, banded with brown ; wings and tail black ; secondaries bronze- 
green ; a white patch as in the male. 

This beautiful Duck^ for our first knowledge of 
which we are indebted to Azara, is rather scarce 
in collections. Azara described the two somewhat 
dissimilar sexes under different names^ the male 
being his Pato collar negro, and the female his Pato 
ceja hlanca. 

In the neighbourhood of Buenos Ayres the Ring- 
necked Teal is strictly migratory^ and in the month 
of October appears in small flocks in the marshes 
along the river ; but in the interior of the country it 
is seldom met with. They are extremely active birds, 
constantly flying about from place to place both by 
day and night ; and in the love-season, when they 
alight in a pool of water, the males immediately 
engage in a spirited combat. While flying they utter 
a peculiar jarring sound, and occasionally a quacking 
note, rapidly repeated and sounding like a strange 
laugh ; but on the water, especially in the evening, 

K II 



146 BIRDS OF LA PLATA 

the male emits a long iimected note, plaintive and 
exquisitely pure in sound — a more melodious note 
it would be difficult to find even among the songsters. 



BRAZILIAN TEAL 

Querquedula brasiliensis 

Above brown ; head more rufous ; lower back, tail, and lesser 
wing-coverts black ; wings brownish black ; outer webs of inner 
primaries and the secondaries shining bronze-green ; broad tips of 
outer secondaries white, divided from the green area by a black band ; 
beneath paler, breast washed with rusty red ; bill and feet orange ; 
length 15.5, wing 7 inches. 

This richly coloured Teal, which is widely extended 
in South America from Guiana down to the Straits 
of Magellan, is usually met with in pairs near Buenos 
Ayres, although as many as five or six are sometimes 
seen together. In habits it is a tree-Duck, preferring 
water-courses in the neighbourhood of woods, and 
is frequently seen perched on hori2;ontal branches. 
The flight is slow and with the wings very much 
depressed, as in a Duck about to alight on the water ; 
and the beautiful blue, green, and white speculum is 
thus rendered very conspicuous. The note of the 
male in the love-season is a long, plaintive whistle, 
singularly pure and sweet in sound, and heard usually 
in the evening. 

It is a rather curious coincidence that the ver- 
nacular name of this Teal in La Plata should be 
Pato Portugues, which means, as things are under- 
stood in that region, Brazilian Duck,

BROWN PINTAIL 147 



BROWN PINTAIL 

Dafila spinicauda 

Above brown ; feathers black in the centre and margined with 
brown ; head above bright rufous spotted with black ; wings brown, 
with a large speculum of bronzy black, distinctly margined above 
and below with buff; beneath, throat dirty white, sparingly spotted 
with black ; breast, flanks, and crissum tinged with rufous, the feathers 
with black centres ; belly white, in the lower portion slightly varied 
with brown ; bill black, at the base yellow ; feet plumbeous ; length 
19, wing 9.7 inches. 

The Brown Pintail is the commonest Duck in the 
Argentine Republic, and unites in the largest flocks. 
It is also, according to Philippi and Landbeck, the 
commonest species in Chili. It ranges from South 
Bra^iil and Peru to the Magellan Straits and the 
Falklands ; but is probably most abundant in the 
Plata district and in North Patagonia. In the autumn 
it sometimes visits the pampas in immense numbers, 
to feed on the seed of the giant thistle {Carduus 
mariana) ; and on these occasions I have known as 
many as sixty killed at one shot. The birds, however, 
soon become wary when feeding on the open plains 
in large flocks, and it then becomes impossible to 
approach them without a trained horse. The Ducks 
pay no attention to horses and cattle browsing near 
them ; and the trained animal, with the gunner con- 
cealing his gun and person behind it, feeds quietly 
along, and gradually approaches the flock until 
within range. In the valley of the Rio Negro, in 
Patagonia, the Pintails sometimes cause serious 



148 BIRDS OF LA PLATA 

damage to the farmers, c^ing up in clouds from 
the river by night to devour the ripe grain. 

In favourable seasons the Pintail is a resident ; 
but like the Marsh-Gulls, Pigeons, the American 
Golden Plover, and all birds that live and move in 
immense bodies, it travels often and far in search 
of food or water. A season of scarcity will quickly 
cause them to disappear from the pampas ; and 
sometimes, after an absence of several months, a 
day's rain will end with the familiar sound of their 
cry and the sight of their long trains winging their 
way across the darkening heavens. 

Their nest is made on the ground, under the grass 
or thistles, at a distance from the water, and is 
plentifully lined with down plucked from the bosom 
of the sitting bird. The eggs are seven or eight in 
number and of a deep cream-colour. 



WHITE-FACED PINTAIL 

Dafila bahamensis 

Above reddish brown ; feather centres blackish ; tail and upper 
tail-coverts fawn ; wings slatey black ; broad speculum bronze-green, 
with fawn margin above and below ; edging of external secondaries 
fawn; beneath brownish fawn, covered with concealed black spots; 
throat, cheeks, and front white ; bill dark with a crimson patch at the 
base in each side ; feet dark ; length i8, wing 8.4 inches. Female 
similar. 

Someone in the eighteenth century picked up a dead 
Duck of an unknown species on the seashore in the 
Bahama Islands : it was then sent to a naturalist in 



WHITE-FACED PINTAIL 149 

Europe who had the naming of all the creatures, and 
quite naturally he gave it the name of Bahamensis. 
And although we know that the duck does not 
inhabit the Bahamas, but is found throughout South 
America from British Guiana to Patagonia, and that 
it is one of the commonest Ducks in Brazil, there is 
a wise ornithological rule which forbids us, while the 
world endures, to call it anything but the Bahama 
Duck or Pintail, I was obliged to give it that name in 
Argentine Ornithology, but I think readers of this book 
in South America will henceforth prefer to call it by 
the name I have given it here* Doubtless there are 
other Pintail Ducks with white faces, but this has 
not given a name to any other species. The Brown 
Pintail is our most abundant species in Argentina, 
and I have noticed in flocks of great size, sometimes 
of many thousands, of that duck, that a single White- 
faced Duck in the flock could be detected at a long 
distance by means of that same snowy whiteness of 
the face. 

On the Pampas and Patagonia it is not a common 
Duck and is almost invariably seen in pairs. I have, 
however, sometimes seen three or four together. 



150 BIRDS OF LA PLATA 



CHILOE WIGEON 

Mareca sibilatrix 

Above black, on the neck barred across with white ; feathers of 
the back and scapularies margined with white ; head above and 
cheeks pure white ; nape and back of the neck shining greenish 
purple ; wings brown, lesser wing-coverts white ; secondaries velvety 
black, white at the base ; beneath white, throat and fore-neck blackish ; 
upper breast black, with narrow white cross-bands ; flanks stained 
with rusty rufous; bill and feet black; length 20, wing 10.3 inches. 
Female similar, but not so bright in colour. 

The Chiloe Wigeon, as this duck has been usually 
called since its introduction and acclimatisation in 
England as an ornamental water-fowl, is the only 
species of the genus found in South America, and is 
most abundant on the pampas, where it is called 
by the country people Pato picaso or Pato overo 
(Piebald Duck) or Chirivi from its cry. It is a very 
handsome bird ; the upper plumage variegated with 
black, white, and grey ; forehead, speculum, and 
under surface white ; head and neck dark glossy 
green. It is resident, and is usually seen in small 
flocks of from a dozen to twenty birds, but sometimes 
as many as one or two hundred congregate together. 
They are wary and loquacious, strong on the wing, 
and frequently engage in a peculiar kind of aerial 
pastime. A small flock will rise to a vast height, 
often until they seem mere specks in the sky, or 
disappear from sight altogether ; and at that great 
altitude they continue hovering or flying, sometimes 
keeping very nearly in the same place for an hour 



RED SHOVELLER 151 

or more, alternately separating and closing, and 
every time they close they slap each other on the 
wing so smartly that the sound may be heard dis- 
tinctly even when the birds are no longer visible. 
While flying or swimming about they constantly 
utter their far-sounding cry— three or four long, 
clear, whistling notes, followed by another uttered 
with great emphasis and concluding with a kind of 

flourish. 

The nest is made amongst the rushes m the 
marshes, and the eggs are pure white and eight or 
nine in number. 



RED SHOVELLER 

spatula platalea 

Above and beneath reddish, with round black spots ; head and 
neck lighter and spots smaller, lower back blackish, barred with 
rufous, rump black; lesser coverts blue; middle coverts white ; 
secondaries bronzy black ; outer secondaries and scapulars with white 
shaft-stripes ; crissum black ; tail brown, lateral rectrices edged with 
white; bill dark, feet yellow; length 20 inches, wmg 8 inches. 
Female, above blackish brown, edged with rufous; lesser wing-coverts 
bluish ; beneath buffy rufous, varied and spotted with blackish except 
on the throat. 

There is but one Shoveller Duck in South America, 
the present species, which is confined to the southern 
part of the continent, from Paraguay to Patagonia, 
and is familiar to sportsmen in the Plata as the Red 
Duck, or Espdtula. It is seldom met with m flocks 
of more than twenty or thirty individuals, and a 



152 BIRDS OF LA PLATA 

large number of birds appe^to pair for life, as they 
are usually seen in pairs at all seasons of the year. 
In the autumn and winter months I have sometimes 
observed small flocks composed of males only, but 
these were perhaps young birds not yet paired. They 
feed in shallow water, where by plunging the head 
down they can reach the mud at the bottom ; and 
when several are seen thus engaged, all with their 
heads and necks immersed, they look curiously like 
headless ducks floating on the water. When dis- 
turbed or flying the male emits a low sputtering 
sound, and this is its only language. They are 
resident, and the least wary of ducks ; never engage, 
like other species, in real or mock combats ; and 
their flight is rapid and violent, the wings beating 
quickly. 



ROSY-BILLED DUCK 

Metopiana peposaca 

Above black, back of head and neck glossed with purple, back 
finely striated with white ; speculum white ; primaries greyish white ; 
belly minutely vermiculated with white and grey ; bill rosy red, 
enlarged at the base, feet yellow; length 19, wing 9.4 inches. Female : 
above brown, bend of wing, speculum, and belly white ; bill and feet 
dull blue. 

The Rosy-billed Duck, usually called ** Black Duck '* 
in the Plata, inhabits the Argentine country from 
Paraguay to Patagonia, and also occurs in Uruguay 
and Chili, but does not extend to Brazil. 



ROSY-BILLED DUCK 153 

A peculiar interest attaches to this species owing 
to the fact that it is the only freshwater Duck in the 
sub-family Fuligulinae, in which it is classed. With 
the exception of the Loggerhead Duck {Tachyeres 
cinereus), found in the Falklands and the Magellan 
Straits^ all the other sea-Ducks of this division in- 
habit North and Central America ; so that the 
Rosy-bill appears to have separated itself widely 
from its nearest relations geographically as well as 
in habits. In appearance it is a fine bird, the black 
plumage being frosted on the upper parts with white 
in a very delicate manner, while the rosy bill and 
large carmine caruncle and golden-red iris contrast 
beautifully with the glossy purple head and neck. 
The speculum is white, the legs bright yellow. The 
plumage of the female is brown. 

In marshy places on the pampas the Rosy-billed 
Duck is very abundant, and they sometimes congre- 
gate in very large flocks. They obtain their food 
from floating weeds in the water, and are never seen, 
like the Pintails and other kinds, feeding on the dry 
land. They rise heavily, the wings being com- 
paratively small, and have a rapid, straight, violent 
flight ; they are nevertheless able to perform long 
journeys, and travel in long lines and at a considerable 
elevation. Their only language is a deep, hoarse, 
prolonged, raven-like note, uttered by the male in 
the love-season. The nest is made on swampy ground 
near the water, of dry rushes, and is, for a Duck, a 
deep well-made structure ; the eggs are oval in form, 
cream-coloured, and twelve in number. 



154 BIRDS OF LA PLATA 

Besides the twelve specif^described there are five 
more Ducks in Argentina, namely : — the Crested 
Duck, Sarcidiornis carunculata ; Muscovy Duck, 
Cairina moschata ; Black-headed Duck, Heteronetta 
melanocephala ; Rusty Lake Duck, Erismatura ferru- 
ginea ; and White-winged Lake Duck, Nomonyx 
dominicus. 

All these species I knew, with the exception of 
the Crested Duck ; but they were rare in my district 
and I could learn nothing of their habits from my 
own observation. 



ARGENTINE WOOD-PIGEON 

Columha picazuro 

Above pale brown ; head and neck vinous ; back of neck with 
white cross-bands which are edged with black ; lower back and tail 
plumbeous ; wings plumbeous, larger coverts broadly edged with 
white"; beneath pale vinaceous ; flanks and crissum plumbeous ; 
length 14 inches, wing 8 inches. Female similar. 

This bird so closely resembles the European Wood- 
Pigeon in its appearance, habits, and language that 
I prefer in this book to drop the name of Picazuro 
Pigeon used in the former work {Argentine Orni- 
thology) and call it the Argentine Wood-Pigeon. The 
chief differences are the absence of the white collar 
and the strangely human-like sound of its notes. 

In summer they inhabit woods, and are seen in 
pairs or small parties, but in winter unite in flocks of 



SPOTTED WOOD-PIGEON 155 

from twenty to one or two hundred individuals, and 
roam much over the open country. It is a wary 
bird, and when feeding walks on the ground in a 
slow, somewhat stately manner. In spring its song 
resounds in the woods, and, when heard for the first 
time, fills the listener with wonder, so human-like 
in tone are its long, mournful notes. The notes are 
five, the last one prolonged, with a falling inflection, 
and profoundly sorrowful. The nest is a platform 
structure, frequently placed on a broad horizontal 
branch ; the eggs are two, and closely resemble those 
of the common Rock-Dove of Europe, 



SPOTTED WOOD-PIGEON 

Columba maculosa 

Above pale vinaceous brown, profusely spotted on the back and 
wings with white apical spots ; lower back and tail plumbeous ; 
wings and tail slatey black, the former with narrow whitish margins ; 
beneath plumbeous, with a strong vinaceous tinge ; bill black, feet 
yellow ; length 13, wing 8.5 inches. Female similar. 

This Pigeon has a general resemblance to the Pica- 
zuro, but may be at once distinguished by its spotted 
back and wings. It ranges from South Peru through 
Bolivia and Western Argentina into Patagonia, where 
it appears to be a resident. In winter the valley of 
the Rio Negro is visited by it in immense flocks, 
which are a great plague to the farmers, as they 
descend in clouds on the fields and devour the wheat 



156 BIRDS OF LA PLATA 

before it has time to sprout#While watching crowds 
of these birds feeding on the ground, I noticed that 
their manner was in striking contrast to that of the 
C. picazuro, which has slow and dignified motions ; 
for it hurried about, and snatched up its food with 
such rapidity that the most animated motions of 
other birds that feed in flocks on the ground seemed 
languid in comparison. This excessively lively habit 
is, no doubt, directly caused by the conditions of 
life ; the sterile soil and scanty vegetation of the 
region it inhabits require in a species going in large 
bodies, and subsisting exclusively on fallen seed, a 
greater activity than is necessary in the rich fertile 
region further north. 

Its song is composed of notes equal in length and 
number to that of the Picazuro, but its voice is 
always hoarse, like that of the European Wood- 
Pigeon, when his early spring song has a low, throaty 
sound, as if the bird was still suffering from the 
effects of a winter cold. 

The great body of these birds retire on the ap- 
proach of summer from the Rio Negro valley, a few 
only remaining to breed. Their nesting-habits and 
eggs are like those of the Picazuro. 



SPOTTED DOVE 157 

SPOTTED DOVE 

* Zenaida maculata 

Above pale brown ; nape plumbeous ; outer wing-coverts and 
scapularies with a few black spots ; wings dark grey, with fine 
white margins ; tail plumbeous, broadly ended with white, and 
crossed by a subapical black band ; middle rectrices like the back ; 
beneath pale vinaceous, brighter on the breast, and whiter on the 
throat ; bill black, feet yellow ; length 9, wing 5.5 inches. Female 
similar. 

This is the commonest species of the Pigeon tribe 
in the Argentine country, and is known to everyone 
as the Torcasa, probably a corruption of Tortola 
(Turtle-Dove)» In autumn they often congregate in 
very large flocks, and are sometimes observed migrat- 
ing, flock succeeding flock, all travelling in a northerly 
direction, and continuing to pass for several conse- 
cutive days. But these autumnal migrations are not 
witnessed every year, nor have I seen any return 
migration in spring ; while the usual autumn and 
winter movements are very irregular, and apparently 
depend altogether on the supply of food. When the 
giant thistle has covered the plains in summer in- 
credible numbers of Torcasas appear later in the season, 
and usually spend the winter on the plains, congregat- 
ing every evening in countless myriads wherever there 
are trees enough to afford a suitable roosting-place. 

On bright warm days in August, the sweet and 
sorrowful sob-like song of this Dove, composed of 
five notes, is heard from every grove — a pleasing, soft, 
murmuring sound, which causes one to experience by 
anticipation the languid summer feehng in his veins. 



158 BIRDS OF LA PLATA 

The nest, as in other Pigffns, is a simple platform 
of slender sticks ; the eggs are oval, white, and two 
in number. The birds appear to breed by preference 
near a human habitation, and do so probably for 
the sake of the protection afforded them ; for the 
Chimango and other birds of prey destroy their eggs 
and young to a large extent. 

One summer a Torcasa laid an egg in the nest of 
one of my Pigeons, built on the large horizontal 
branch of a tree at some distance from the dove- 
cote. The egg was hatched, and the young bird 
reared by its foster-parents ; and when able to fly 
it took up its abode along with the other Pigeons. 
The following spring it began to separate itself from 
its companions, and would fly to the porch, and sit 
there cooing by the hour every day* At length it 
went away to the plantation, having, I believe, found 
a mate, and we saw no more of it. 



PIGMY DOVE 

Columbula picui 

Above brownish ash-colour ; head and neck dove grey ; wing 
feathers black ; coverts and secondaries like the back, white on their 
outer edges, a band of bright blue across the tips of the lesser 
coverts ; tail white, except the two central feathers, which are hke 
the back ; beneath pale vinaceous ; throat white ; under wing- 
coverts black ; bill dark, feet yellow ; length 6.5, wing 3.5 inches. 
Female similar but duller. 

This species, the smallest of our Doves, is common 
everywhere in the Plata district, where it is called 
Tortolita (Little Turtle-Dove), Azara's name Picul 
not being known to our countrymen. 



SOLITARY PIGEON 159 

It is usually seen with its mate, for many indivi- 
duals seem to pair for life ; but sometimes a dozen 
or twenty individuals unite in one flock. It is resident, 
comes a great deal about houses, and is familiar with 
man, and lively in its habits. It sings a great deal in 
summer and even on warm days in winter ; but its 
tones are wanting in the wild pathos which gives a 
charm to the melody of some of our larger species, 
the song consisting of a succession of long, rather 
loud, and somewhat monotonous notes, pleasant to 
hear, like most bird-music, but nothing more. 

The nest is the usual slight structure of sticks ; the 
eggs two, oval, and white. They breed twice, and 
sometimes three times, in one season, the last brood 
being hatched as late as April or even May, 



SOLITARY PIGEON 

Engyptila chalcauchenia 

Above greyish brown, head and nape plumbeous ; back of neck 
with the feathers edged with iridescent bronzy green ; tail blackish, 
broadly tipped with white ; central rectrices like the back ; beneath 
pale vinaceous ; middle of throat, belly, and crissum white ; under 
surface of wings bright chestnut ; bill black, feet yellowish ; length 
10, wing 5.7 inches. Female similar. 

This Dove, which is a southern form of a widely 
distributed group of species of the genus Engyptila, 
formerly called Leptoptila, inhabits the woods of the 
Plata district, and never, like other Pigeons, seeks 
the open country to feed. It is solitary, although, 
where many birds live in close proximity, three or 



i6o BIRDS OF LA PLATA 

four may be sometimes seen in company. It spends 
a great deal of time on the ground, where it walks 
about under the trees rather briskly, searching for 
seeds and berries. Their song is a single uninflected 
and rather musical note, which the bird repeats at 
short intervals, especially in the evening during the 
warm season. Where the birds are abundant the 
wood, just before sunset, becomes vocal with their 
curious far-sounding notes ; and as this evening 
song is heard as long as the genial weather lasts, it 
is probably not related to the sexual instinct. The 
nest is a simple platform; the eggs are two, and 
white, but m^ore spherical in shape than those of 
most other Pigeons. 

Besides the five Pigeons I have described there 
are three more species in Argentina, confined to the 
northern part of the country. South America is 
rich in Pigeons, the species numbering sixty or 
seventy. 



BLACK RAIL 

Rallus rhytirhynchus 

Above greenish brown ; beneath plumbeous ; bill incurved^ 
greenish, with a blood-red basal spot ; feet red ; length 12, wing 
5.4 inches. Female similar. 

This Rail differs from the other species in its beak, 
which is very long and curved, as in the Painted 
Snipe {Rhynchsea), and has three strongly contrasted 
colours — dark green, bright blue, and scarlet at the 



BLACK RAIL i6i 

base. The blue and red tints become very vivid in 
the love-season. Without being anywhere abundant, 
the Black Rail is found throughout the Plata region 
in every place where reeds and rushes grow. In the 
marshes along the Plata they are met with quite as 
frequently in winter as in summer ; this fact sur- 
prised me greatly, since I know this species to be 
migratory, their unmistakable cries being heard 
overhead every night in spring and autumn, when 
they are performing their distant journeys. Probably 
all the birds frequenting the inland marshes on the 
south-western pampas migrate north in winter, and 
all those inhabiting the Plata marshes and the Atlantic 
sea-board, where there is abundant shelter and a 
higher temperature, remain all the year. On the 
Rio Negro of Patagonia I found the Black Rail a 
resident, but the winter of that district is singularly 
mild ; moreover, the wide expanse of waterless 
country lying between the Rio Negro and the moist 
pampas region would make an annual migration 
from the former places difficult to such a feeble flier. 
Of this instinct we know at least that it is hereditary ; 
and it becomes hard to believe that from every one 
of the reed-beds distributed over the vast country 
inhabited by this species a little contingent of migrants 
is drawn away annually to winter elsewhere, leaving 
a larger number behind. Such a difference of habit 
cannot exist among individuals of a species in one 
locality ; but differences in the migratory as in other 
instincts, great as this, are found in races inhabiting 
isolated or widely separated districts.

i62 BIRDS OF LA PLATA 

It is difficult to flush tMPBlack Rail ; it rises in a 
weak fluttering manner, the legs dangling down, and 
after flying thirty or forty yards drops again into the 
reeds. Its language is curious : when alarmed the 
bird repeats, at short intervals, a note almost painful 
from its excessive sharpness, and utters it standing 
on a low branch or other elevation, but well masked 
by reeds and bushes, and incessantly bobbing its 
head, jerking its tail, and briskly turning from side 
to side. It has at such times a very interesting 
appearance, while the long beak, brilliant with the 
nuptial colouring, the bright red eye and vermilion 
legs, admirably contrasting with the fine deep slate 
plumage, give it considerable claims to beauty. At 
other times it has a hollow call-note with a puzzling 
ventriloquism in the sound, wliich is sometimes 
repeated at short intervals for an hour. While utter- 
ing it the bird stands as usual on a slight eminence, 
but drawn up in a listless attitude and without any 
of its nods and jerks and other frisky gestures. It 
has also a kind of song, which sounds not unlike the 
braying of a donkey ; hence the vernacular name 
Burrito (Little Ass) by which the bird is known in the 
Plata. This song is heard both day and night, and 
is a confused performance, uttered without pause, 
and composed of several long shrill notes, modulated 
and mingled with others hollow and booming. These 
notes can be heard a thousand yards away ; but, far 
or near, they always sound remote. 



YPECAHA RAIL 163 



YPECAHA RAIL 

Aramides ypecaha 

Above olive-green ; neck red ; front cinereous ; rump and tail 
black ; beneath^ throat white, breast and neck cinereous ; abdomen 
rosy red, lower belly and thighs grey ; flanks and crissum black ; 
under wing-coverts rufous, with black cross-bars ; bill yellow, feet 
red ; length 19, wing 8.5 inches. Female similar. 

Ypecaha is the Guarani name^ preserved by 
Azara, of this highly interesting species ; by the 
Spanish it is called Gallinetaf from its supposed 
resemblance to a fowl. Without any brilliant tints, 
there is yet something so pleasing to the eye in the 
various hues of its plumage — light brown and drab 
colour, grey, buff, and black — all these colours so 
harmoniously disposed, the effect heightened by the 
long, straight yellow beak, golden-red eye, and ver- 
milion legs, that I do not know a handsomer water- 
fowl. 

These Rails are found as far south as the thirty- 
fifth parallel of latitude, and are abundant along the 
marshy borders of the Plata, frequenting the vast 
reed-beds and forests of water-loving Erythrina 
cristagalli. Where they are never persecuted they 
are bold, pugnacious birds, coming out of the reeds 
by day and attacking the domestic poultry about the 
houses and even in the streets of the villages situated 
on the borders of their marshy haunts. But when they 
are compelled to place man on the list of their enemies, 
it is a difficult matter to get a sight of one ; for, like 



i64 BIRDS OF LA PLATA 

all birds that rise labori<^ly; they are vigilant to 
excess, and keep themselves so well concealed that 
the sportsman may pass through their haunts every 
day of the year and the Ypecaha still be to him no 
more than a ** wandering voice/' But even persecu- 
tion does not obliterate a certain inquisitive bold- 
ness which characterises them. Usually they roam 
singly in quest of food, but have reunions in the 
evening and occasionally during the day, especially 
in gloomy weather. On misty days they often wander 
to a distance from the covert, walking with an easy, 
somewhat stately grace, jerking the tail at every 
stride, and running with a velocity no man can 
equal. Where there are woods they usually fly when 
disturbed into a tree ; and it is in connection with 
this habit that the Ypecaha sometimes makes a 
curious mistake in places where it has not been 
much shot at. One day, while pushing my way 
through a dense grov^lih of rushes, I saw two Ypecahas 
not fifteen yards from me, on the horizontal branch 
of a tree, to which they had evidently flown for 
safety. I was anxious to secure them, but surprised 
at their temerity ; and wishing to find out its cause, 
I approached them still nearer, and then stood for 
some time observing them. It was easy to see that 
they fancied themselves quite safe from me while 
off the ground. In the most unconcerned manner 
they continued strutting up and down along the 
branch, jerking their tails, and turning about this 
way and that, as if to tantalise their baffled enemy 
by ostentatiously displaying their graces. 



YPECAHA RAIL 165 

When surprised on the open ground the Ypecaha 
lies close, like a Tinamu, refusing to rise until 
almost trodden upon. It springs up with a loud- 
sounding whirr, rushes violently through the air till, 
gaining the reeds, it glides a few yards and then 
drops ; its flight is thus precisely like that of the 
Tinamu, and is more sounding and violent than 
that of the Grouse or Partridge, On spying an 
intruder it immediately utters a powerful cry, in 
strength and intonation not unlike that of the Pea- 
fowl. This note of alarm is answered by other birds 
at a distance as they hastily advance to the spot 
where the warning was sounded. The cry is repeated 
at irregular intervals, first on one side, then on the 
other, as the birds change their position to dog the 
intruder's steps and inspect him from the reeds. 
I have surprised parties of them in an open space, 
and shot one or more ; but no sooner had the sur- 
vivors gained their refuge than they turned about 
to watch and follow me, sounding their powerful 
alarm the whole time. I have frequently been 
followed half a mile through the rushes by them, 
and by lying close and mimicking their cries have 
always succeeded in drawing them about me. 

But the Ypecaha's loudest notes of alarm are weak 
compared with the cries he utters at other times, 
when, untroubled with a strange presence, he pours 
out his soul in screams and shrieks that amaze the 
listener with their unparalleled power. These 
screams in all their changes and modulations have 
a resemblance to the human voice, but to the human 



i66 BIRDS OF LA PLATA 

voice exerted to its utmost pitch, and expressive of 
agony, frenzy, and despair. A long, piercing shriek, 
astonishing for its strength and vehemence, is suc- 
ceeded by a lower note, as if in the first one the 
creature had wellnigh exhausted itself. The double 
scream is repeated several times ; then follow other 
sounds, resembling, as they rise and fall, half-sup- 
pressed cries of pain and moans of anguish. Suddenly 
the unearthly shrieks are renewed in all their power. 
This is kept up for some time, several birds scream- 
ing in concert ; it is renewed at intervals throughout 
the day, and again at set of sun, when the woods and 
marshes resound with the extravagant uproar. I have 
said that several birds unite in screaming ; this is 
invariably the case. I have enjoyed the rare pleasure 
of witnessing the birds at such times ; and the 
screams then seem a fit accompaniment to their 
disordered gestures and motions. 

A dozen or twenty birds have their place of reunion 
on a small area of smooth, clean ground surrounded 
by rushes or sedges ; and by lying well concealed 
and exercising some patience, one is enabled to watch 
their proceedings. First one bird is heard to utter 
a loud metallic-sounding note, three times repeated, 
and somewhat like the call of the Guinea-fowl. It 
issues from the reeds or rushes, and is a note of 
invitation quickly responded to by other birds on 
every hand as they all hurriedly repair to the 
customary spot. In a few moments, and almost 
simultaneously, the birds appear, emerging from 
the reeds and running into the open space, where 



YPECAHA RAIL 167 

they all immediately wheel about and begin the 
exhibition. 

Whilst screaming they rush from side to side as if 
possessed with frenzy^ the wings spread and agitated, 
the beak wide open and raised vertically, I never 
observed them fight or manifest anger towards each 
other during these performances ; and knowing the 
pugnacious spirit of the Ypecahas, and how ready 
they are to seek a quarrel with birds of other species, 
this at first surprised me, for I was then under the 
mistaken impression that these gatherings were in 
some way related to the sexual instinct. 

Whilst watching them I also remarked another 
circumstance. When concealing myself amongst the 
rushes I have been compelled to place myself so 
disadvantageous^, owing to the wet ground, that 
any single bird straying accidentally into the open 
space would have discovered my presence immed- 
iately ; yet the birds have entered and finished their 
performance without seeing me, so carried away 
are they by the emotion that possesses them during 
these moments. But no sooner has the wild chorus 
ended, than, aware of my presence, they have fled 
precipitately into the reeds. 

We frequently speak of our familiarity with the 
habits of the species we have long and carefully 
observed in a state of nature ; yet the knowledge so 
gained must necessarily be exceedingly imperfect, for 
with many shy vigilant birds it is next to impossible 
to see them without being seen ; and no bird, con- 
scious of being watched, will act unconstrainedly 



i68 BIRDS OF LA PLATA 

any more than a human biiRg with clouded reputa- 
tion will comport himself naturally with the eyes 
of a detective on him. While we are observing 
the bird, the bird watches us : of all its curious 
doings when we are out of sight and mind we see 
nothing. The only way to learn the habits of a species 
like the Ypecaha — wary, inteUigent, and passing its 
life behind a screen of rushes — is to domesticate it ; 
for although in this state some instincts are blunted 
and others remain in abeyance, they are not obliter- 
ated. It might surprise some that I speak of the 
Ypecaha as an intelligent bird, since it is a member 
of the '* stupid family/' as Professor Parker has called 
the Rails ; but in spite of the very profound admir- 
ation I feel for that illustrious anatomist, I believe 
he is wrong about these birds : there is, to my mind, 
very much more stupidity in the Anserine and 
Limicoline families, while the Ypecaha has always 
seemed to me a singularly intelligent bird. 

Fortunately A^ara was able to give an account of 
one of these birds in a domestic state, which shows 
that it makes a very sprightly and entertaining al- 
though a mischievous pet. It was taken young and 
allowed to run about at liberty with the poultry at 
the house of a village doctor in Paraguay. When 
full-grown it was very domineering, and became the 
tyrant of the poultry-yard. Occasionally a cock had 
the courage to face it, and then a singular combat 
would ensue : the Ypecaha, moving with astonishing 
rapidity, putting its head low, would charge, and, 
thrusting its head between the cock's legs, fling him 



YPECAHA RAIL 169 

instantly on his back, then rain a shower of blows on 
his breast before he could rise. It was fond of eggs, 
and always knew when a hen went off to lay, cautiously 
following her to the nest and then concealing itself 
at some distance to wait. As soon as the egg was 
dropped it would run, pick it up with its beak, and 
carry it away to a safe distance, and then, breaking 
a hole in the shell at one end, suck out the contents 
without spilling a drop. Sometimes, when the hen 
remained too long on the nest, it would lose its 
temper, and, driving her off, pursue her with the 
greatest animosity about the grounds, administering 
correction with its sharp beak. Not satisfied with 
devouring all the eggs laid by the doctor^s fowls, it 
visited all the neighbours* houses, doing so much 
damage that at length the poor doctor, afraid perhaps 
that his practice would suffer, had the troublesome 
bird put to death. 

This Ypecaha would never allow any one to touch 
it, but it would come into the house and search 
through all the rooms for thimbles, scissors, and 
other small metal objects, and these it would carry 
away to conceal them among the weeds or else bury 
them in the mud. It was also a good mouser, and 
after killing a mouse with a blow from its beak would 
swallow it entire. 



170 BIRDS OF LA PLATA 

LITTLE VC^TERHEN 

Porphyriops melanops 

Above olivaceous ; head darker ; wings brown ; wing-coverts tinged 
with chestnut ; outer secondaries more or less distinctly margined 
with white ; beneath cinereous ; middle of belly and crissum white ; 
flanks ohvaceous, spotted with white ; bill dark ohve, with the tip 
yellowish ; feet hazel ; length 9, wing 5 inches. Female similar. 

In the southern part of the Argentine country the 
Little Waterhen is a summer visitant, and very 
abundant in the marshes along the Plata. In language 
and habits it is like the Coots : it is not often seen on 
land, and feeds principally as it swims about in a 
jerky manner among the floating reeds. It appears 
in October, migrating exclusively, I think, by night ; 
and after the autumnal departure an individual is 
rarely seen. By day they are shy and retiring, but 
scatter abroad in the evening, frequently uttering 
their hollow mysterious cry, called ** the witch laugh'' 
by superstitious people, and resembling a sudden 
burst of hysterical laughter, the notes beginning 
loud and long, becoming brief and hurried as they 
die away. 

YELLOW-BILLED COOT 

Fulica leucoptera 

Dark slatey ; head and neck black ; crissum white, with a black 
median patch ; bend of wing and outer margin of external primary, 
also the tips of some of the secondaries, white ; bill yellow ; head- 
shield rounded behind ; feet olivaceous ; length 15, wing 7.5 inches. 
Female similar. 

This is perhaps the most abundant species of Fulica 
in the Plata region, and certainly congregates in the 



YELLOW-BILLED COOT 171 

largest numbers. The colour of the beak and shield 
is of a very delicate yellow ; the legs and feet dull 
green ; the head, neck, and part of the back velvet- 
black ; all the rest of the plumage dark slate-colour, 
except the under-coverts of the tail, which are white 
and render the bird very conspicuous when it is 
swimming away with the tail raised vertically. 

On the pampas, in large marshy lagoons, this 
Coot is sometimes seen in immense numbers ; 
thousands of birds uniting in one flock, and spreading 
over the low shores to feed, they look like a great 
concourse of Rooks. But they are exceedingly timid, 
and at the sight of a bird of prey or other enemy they 
all scuttle back to the water, tumbling over each 
other in their haste to reach it. They rise in a peculiar 
manner, rapidly striking the surface of the water 
with their great lobed feet, often for a distance of 
twenty or thirty yards before they are fully launched 
in the air. They are loquacious birds, and when 
swimming about concealed among the thick rushes 
are heard answering each other in a variety of curious 
tones, some of their loud, hollow-sounding, reiterated 
cries resembling peals of laughter. 

The nest is a slovenly structure of rushes lying 
on the water, with a very slight depression for the 
eggs, which are ten or twelve in number. These are 
long, pointed at one end, dull cream-colour, marked 
over the whole surface with small blackish and purple 
spots. 

There are two other species of Coots in Argentina : 
the Red-gartered Coot, F. armillata, the largest 



172 BIRDS OF LA PLATA 

species^ which like the last IRs a yellow shield, but 
bordered with red and the bare portions of the tibiae 
crimson ; hence the name : and the Red-fronted 
Coot, F, leucopyga, with beak and shield scarlet. 

Altogether the Family Rallidae counts thirteen 
species in Argentina : eight Rails and Crakes, two 
Waterhens, and three Coots. 



ARGENTINE COURLAN 

Aramus scolopaceus 

Above brown ; forehead, lores, and chin greyish white ; neck 
striped with white ; beneath similar ; bill brown ; legs greenish grey ; 
length 24, wing 13 inches. Female similar. 

This curious bird has a blackish-brown plumage, 
glossed with bronze on the upper parts ; its total 
length is about two feet and a half, and the wings, 
when spread, measure nearly four feet from tip to 
tip. It has been called ** an abnormal relative of the 
Rails at most," and in its peculiar flight and many 
of its habits certainly differs very widely from the 
Rails. It has but one known relative, the Giant 
Courlan of northern South America, a rare species 
about whose habits little is known. 

The beak of this bird is nearly five inches long, 
straight, and of an iron hardness ; the tip is sHghtly 
bent to one side, the lower mandible somewhat more 
than the upper. The tongue extends to the extremity 



ARGENTINE COURLAN 173 

of the beak ; at the end it is of a horny toughness, 
and frayed or split into filaments. This beak is a most 
effective instrument in opening shells ; for where 
molluscs abound the Courlan subsists exclusively 
on them, so that the margins of the streams which 
this bird frequents are strewn with innumerable 
shells lying open and emptied of their contents. 

Every shell has an angular piece, half an inch long, 
broken from the edge of one valve. Mussels and 
clams close their shells so tightly that it would perhaps 
be impossible for a bird to insert his beak, however 
knife-like in shape and hardness, between the valves 
in order to force them open ; therefore I believe 
the Courlan first feels the shell with his foot whilst 
wading, then with quick dexterity strikes his beak 
into it before it closes, and so conveys it to the shore. 
Otherwise it would be most difficult for the bird to 
lift the closed shell from the water and to carry it to 
land ; but supposing it could do this, and afterwards 
succeed in drilling a hole through it with its beak, 
the hole thus made would have jagged edges and be 
irregular in shape. But the hole is, as I have said, 
angular and with a clean edge, showing that the bird 
had just thrust his beak half an inch or an inch 
between the valves, then forced them open, breaking 
the piece out during the process, and probably 
keeping the shell steady by pressing on it with its 
feet. 

By day the Courlan is a dull bird, concealing 
itself in dense reed-beds in streams and marshes. 
When driven up he rises laboriously, the legs dangling 



174 BIRDS OF LA PLATA 

down, and mounts verticallygR) a considerable height* 
He flies high, the wings curved upward and violently 
flapped at irregular intervals ; descending he drops 
suddenly to the earth, the wings motionless, pointing 
up, and the body swaying from side to side, so that 
the bird presents the appearance of a falling para- 
chute. On smooth ground he walks faster than a 
man, striking out his feet in a stately manner and 
jerking the tail, and runs rapidly ten or twelve yards 
before rising. At the approach of night he becomes 
active, uttering long, clear, piercing cries many times 
repeated, and heard distinctly two miles away. These 
cries are most melancholy, and together with its 
mourning plumage and recluse habits have won for 
the Courlan some pretty vernacular names. He is 
called the '* Lamenting Bird " and the ** Crazy 
Widow," but is more familiarly known as the 
Carau. 

Near sunset the Caraus leave the reed-beds and 
begin to ascend the streams to visit their favourite 
fishing-grounds. They are very active at night, 
retiring again at the approach of morning, and 
sometimes pass the day perched on trees, but 
more frequently concealed in dense rush-beds. 

As the breeding-season draws near they become 
exceedingly clamorous, making the marshes resound 
day and night with their long, wailing cries. The nest 
is built among the rushes, and contains ten or twelve 
eggs big as a Turkey's eggs, and very large for the si2;e 
of the bird, slightly elliptical, sparsely marked with 
blotches of pale brown and purple on a dull white 




Common Jacana 

Parra jacana (Lijin.) 



JACANA 175 

ground^ the whole egg having a powdered or floury 
appearance. When the nest is approached the parent 
birds utter sharp^ angry notes as they walk about 
at a distance. The young and old birds live in one 
flock until the following spring* 

The Carau is more nocturnal than the true Rails, 
and, having a far more powerful flight, takes to wing 
more readily ; in its gestures and motions on the 
ground it resembles them, but differs strikingly from 
all Ralline birds in the habit it possesses of flying 
when disturbed to some open place, where it walks 
about conspicuously, watching the intruder. 



JACANA 

Parra jacana 

Head and neck purplish black ; back and wings bright chestnut ; 
primaries and secondaries pale greenish yellow tipped with brown ; 
flanks dark chestnut ; breast dark black ; abdomen purplish ; the tail 
chestnut tipped with black ; wattles on head and base of bill red, 
rest of bill yellow ; feet olive ; length 10.5, wing 5.8 inches. Female 
similar. 

The beautiful Jacana — pronounced something like 
Yasand — also called in the vernacular Alas-amarillas 
(Yellow- wings), differs very widely from all the other 
members of the Limicoline Order in which it is 
placed, in the enormously elongated toes which 
enable it to run about on the floating leaves of water 
plants. It is supposed to come nearest to the Plovers, 



176 BIRDS OF LA PLATA 

but is more like a Rail itf0ts appearance, which is 
most singular. 

The colouring of the plumage heightens the 
singularity of its appearance : the head, neck, and 
underparts being black ; the shoulders, back, and 
wing-coverts chestnut ; while the quills, which have 
a bright satiny lustre, are apple-green in colour, and 
in some lights appear golden-yellow. 

In the southern part of the Plata district the Jacana 
is migratory, arriving from the north in Buenos 
Ayres early in October, either singly or in small 
parties. In their migration they appear to follow 
the course of the Plata ; and though some individuals 
are found breeding inland, they are for the most 
part confined to the littoral marshes. 

The Jacanas journey by very easy stages, fre- 
quently alighting to rest by the way ; for they are so 
incapable of sustained flight that boys on the pampas 
occasionally take them, pursuing them on horseback 
till the birds drop down exhausted. I believe the 
migratory Rails travel in the same way — a matter not 
easily determined, as they migrate by night ; but 
th)ey are feeble- winged creatures, and when driven 
to rise flutter away as if wounded. I have observed 
the Jacanas migrating by day, but would not for this 
reason affirm that they do not journey by night, 
since the Bartram's Sandpiper and other species 
journey both day and night. 

The Jacana flies swiftly, in a straight line and 
close to the surface ; the wings flutter rapidly, and 
there are frequent intervals of gliding. When rising 



JACANA 177 

it presents a most novel appearance^ as the lovely 
golden-green of the wings is quite concealed when 
the bird is at rest ; the beauty of its flight is thus 
greatly enhanced by the sudden display of a hue so 
rare and delicate. At a distance from the beholder, 
and in a strong sunshine, the wings appear of a 
shining golden yellow. Not only when flying does the 
Jacana make a display of its beautiful wings ; without 
rising it has a way of exhibiting them, appearing to 
delight as much in them as the Cockatoo does in its 
crest or the Peacock in its train. When several of 
these birds live in company, occasionally they all in 
one moment leave their feeding, and with quick 
excited notes, and clustering together in a close 
group, go through a singular and pretty performance, 
all together holding their wings outstretched and 
agitated, some with a rapid fluttering, others with a 
slow-moving leisurely motion like that of a butterfly 
sunning itself. The performance over, the birds 
peaceably scatter again. I have never observed 
Jacanas fighting. 

Shortly after arriving they pair, and build a simple 
nest with few materials, usually on the floating weeds. 
The eggs are four, in shape like a Snipers eggs, spotted 
with chestnut on a pale yellowish-brown ground. 
During incubation the male keeps guard at some 
distance from the nest, and utters a warning cry 
at the approach of an intruder ; the female instantly 
flies from the nest, but in rising renders herself 
very conspicuous. When the nest is approached 
the parent birds hover about, occasionally fluttering

178 BIRDS OF LA PLATA 

as if wounded, all the tme keeping up a clamour 
of hurried, angry notes somewhat resembling the 
yelping cries of the Stilt. 



SPUR-WING LAPWING 

Vanellus cayennensis 

Above grey ; broad front and vertical crest black ; patch on the 
scapulars purplish bronze ; upper tail-coverts white ; primaries 
purplish black ; greater coverts white ; lesser wing-coverts bronze 
green ; tail, basal half white, the other half purple-black tipped with 
white ; beneath, chin, line down the middle of the throat and breast 
shining black ; sides of neck grey, passing into white on the face ; 
abdomen and under wing-coverts white ; bill, spur on wing, and feet 
red ; eyes crimson; length 13, wing 8.2 inches. Female similar. 

The Lapwing of La Plata is considerably larger than 
the well-known Lapwing of the Old World, but 
closely resembles that bird in the general colour of 
the plumage, in the long, slender, black crest, and 
in general appearance. Throughout the Argentine 
country it is called Teru-teru, from its ever-repeated 
disyllabic cry ; west of the Andes the vernacular 
name is Qaeltregua, also in imitation of its notes. It 
has red legs, crimson irides, a rosy beak tipped with 
black, and coral-red wing-spurs ; and these spots of 
bright colour add to its bold, striking appearance. In 
size, beauty, and spirit it is a king among the Plovers, 
while its jealous, aggressive disposition gives it the 
character of a tyrant amongst birds in general. On 
the pastoral pampas (the district from which the 



SPUR-WING LAPWING 179 

giant grasses have disappeared) it is (or was) exces- 
sively abundant ; and it is there resident^ although, 
as with most strong-winged resident species, some 
individuals do certainly migrate, small parties being 
occasionally seen in spring and autumn flying steadily 
at a great height, apparently performing a long 
journey. As a rule the birds pair for life, and remain 
always on the spot where they breed. They may be 
persecuted with guns, their eggs taken year after 
year, even the ground turned up with the plough, 
but they still refuse to be driven out. In regions 
having a broken surface — hills, woods, and sheltered 
hollows — birds naturally get attached to one spot, 
for each locality possesses its own features, and 
individuals frequenting it acquire a knowledge of 
its advantages* The vast pampas have a uniform 
level surface, and produce the same kinds of food 
in the same quantities. They are parched with 
droughts and flooded by rains alternately, and swept 
by dust storms in summer and cold gales in winter 
— violent enough, one would imagine, to drive every 
winged creature away and obliterate all marks of 
home. Again, the powerful flight of this species 
would enable it to take long journeys, and if un- 
affected by atmospheric changes, scarcity of food 
and water might be a temptation to seek new regions. 
But through all vicissitudes the Teru-teru clings to 
its chosen spot of ground. 

In defence of its territory it wages perpetual war 
against most living creatures, the objects of its special 
abhorrence being men, dogs, Rheas, and birds of 



i8o BIRDS OF LA PLATA 

prey generally. Its noi^cry and irascible temper 
are spoken of by most travellers and naturalists ; 
for no person riding across the pampas could possibly 
overlook the bird, with its screaming protests against 
all trespassers perpetually ringing in his ears ; but 
they have all omitted to mention the singular habit 
which this bird has of associating in sets of three 
for the purpose of amusement or play. Each couple, 
as I have said, live always together on their own 
pretty well - defined plot of ground, which they 
jealously guard from intrusion. Yet if you watch 
a pair of them for a while you will presently see 
another bird — one of a neighbouring couple — rise 
up and fly to them, leaving his own mate to take care 
of home ; and instead of resenting this visit as an 
intrusion, they welcome it with notes and signs of 
manifest pleasure. Advancing to the visitor, they 
place themselves behind it, and then all three, keeping 
step, begin a rapid march, uttering loud drumming 
and rhythmical notes in time with their movements, 
the notes of the birds behind coming in a rapid 
stream, while the leading bird utters loud single notes 
at regular intervals. The march ceases, the leader 
stretches out his wings, still emitting loud notes, 
while the other two, with puffed-out plumage, 
standing exactly abreast, stoop forward until the 
tips of their beaks touch the ground, and, sinking 
their voices to a murmur, remain for some time in 
this singular posture. The performance is then over ; 
the birds all resume their natural attitudes, and the 
visitor takes his leave. It is quite certain that this 



SPUR-WING LAPWING i8i 

display has no connection with the sexual feeling, 
for it is indulged in all the year round, at all hours 
of the day, and also during moonlight nights* It is 
simply the bird's manner of expressing its joyous 
spirits ; for most living creatures — birds especially 
— have more or less well-defined methods of playing ; 
and play-day with the Teru is every day, and at 
brief intervals* And yet the grave, pompous air of 
the birds, and the military precision of their move- 
ments, might easily lead an observer to attribute 
these displays to some more important motive. Play 
is not only indulged in with neighbours ; there are 
many solitary T^rus continually wandering about 
from place to place — probably young birds not yet 
settled in life — ^and when one of these vagrants passes 
near a pair he is immediately invited to join them, 
and when he alights all go through the performance 
together with great zest. In this case, however, as 
soon as it is over, the strange bird is attacked with 
great spirit and chased away ; and if by chance he 
comes down again near them, they hasten to drive 
him up with increased fury. He is wanted only for 
five or six minutes and must not outstay his welcome. 
While watching their antics, which the gauchos 
call the Teru's quadrilles, a curious subject of 
enquiry suggested itself to my mind. It appeared 
to me that its manner of playing has had a reflex 
effect strong enough to mark the bird's whole charac- 
ter — slanguage, bearing, and habits being coloured by 
it, and even the domestic relations interfered with. 
And with regard to the latter point, though it is the 



i82 BIRDS OF LA PLATA 

rule that each cock bird nas only one hen, I have 
known several instances of a cock with two hens, 
the two females laying their eggs in one nest and 
taking turns in sitting on them. I have also found 
instances of two males to one female ; and in one 
case where I watched the birds I noticed that when 
the female was on the nest the males stood over her, 
one on each side. 

I once had my attention drawn to a large concourse 
of Terus by the strange behaviour of two individuals 
amongst them, and I stayed to watch their proceed- 
ings. It was in the dry, hot weather, and a great 
many birds had congregated to drink at a lagoon. 
Some hundreds of them were standing about, quietly 
preening their feathers, and in the middle of the 
flock two birds were conspicuously marching about, 
stiff and upright as a couple of soldiers engaged in 
some military exercise, and uttering loud notes full 
of authority. Every few minutes a fresh bird would 
arrive and alight at some distance from the water, 
on which the two noisy birds would bustle up, and, 
ranging themselves behind it, run it with loud drum- 
ming notes to the margin ; then, standing close 
together, they would wait till its thirst was quenched, 
after which they would run it away to some distance 
from the water, of which they seemed to have made 
themselves dispensers. For over an hour I continued 
watching them, and every bird that arrived was 
conducted to and from the water in this ceremonious 
manner. 

Occasionally several couples unite and soar about 



SPUR-WING LAPWING 183 

in a compact flock ; they divide into sets of three 
birds each, then hover for some time, all waving 
their wings exactly in time and screaming their notes 
in unison, and these movements seem like an imita- 
tion in the air of the usual marching and drumming 
performance on the ground. 

The breeding-season of the Terus begins as early 
as the month of June in favourable seasons ; severe 
cold, drought, or other causes sometimes delay it to 
August, The nest is a shallow circular hollow made 
by the bird on the level plain, and lined with broken 
grass-stems and small fragments of thistle-stalks ; 
the eggs are four, rather sharply pointed at one end, 
and have an olive-green ground colour spotted with 
black. The eggs in different nests vary greatly in 
si^e, ground colour, and in the amount of black they 
are marked with, no two birds laying eggs exactly 
alike. 

While the female is on the nest the male keeps 
watch at a distance of twenty or thirty yards, and 
utters a low warning cry in case of danger. The 
female leaves the nest sometimes by running, but 
oftener flies from it, and by marking the spot she 
rises from it is easy to find the nest on the open level 
pampas. In the course of a morning^s ride I have 
picked up as many as sixty-four eggs. During 
incubation the birds are excessively watchful and 
jealous, their irritability increasing with the growth 
of the chick in the shell ; and at that time they 
will attack any bird of prey approaching the nest 
with great fury. When approached by a human 



i84 BIRDS OF LA PLATA 

being they fly to meet him wien he is still far from 
them, and hovering, with loud screams, over him, 
dash down at intervals, threatening to strike with 
their wing-spurs, coming very close to his head. 
Unable to intimidate the enemy with this show of 
violence the bird changes its tactics, and, alighting 
at some distance, counterfeits the action of a bird 
seeking its nest. With well-acted caution and secrecy 
in its manner, it runs silently along, stooping low, 
and having found a slight nest-like depression on 
the surface, sits on it, half opens its wings, and begins 
gathering all the small sticks or straws within its 
reach and carefully arranges them about it, as most 
ground-breeding birds do when incubating. Some- 
times also, like many other species, it tries to lead 
one away from the nest by feigning lameness ; but 
the former instinct of seeking and sitting on an 
imaginary nest, which I have not observed in any 
other bird, seems far more complex and admirable. 

When sheep in a flock pass over the nest, the bird 
stands on it to defend its eggs ; and then its loud 
cries and outspread wings often serve to bring the 
sheep, from motives of curiosity, about it. Even 
with a dozen sheep clustered round it the bird stands 
undaunted, beating their faces with its wings ; but, 
unhappily for it, if the shepherd is following, the 
loud cries of the bird bring him to the spot, and the 
eggs so bravely defended are taken. 



AMERICAN GOLDEN PLOVER 185 



AMERICAN GOLDEN PLOVER 

Charadrius dominicus 

Above brownish black, with numerous irregular spots of yellow ; 
forehead, superciliary stripe, and sides of neck white ; beneath black ; 
crissum whitish ; axillaries smoky grey ; bill black ; feet dark grey ; 
length 10.5, wing 7 inches. Female similar. Young, beneath dirty 
white, with greyish freckles. 

This closely allied representative of the Golden 
Plover of Europe, from which it is distinguishable 
mainly by its rather larger si2;e and smoky-grey 
axillaries, visits South America after its breeding 
season in the north. 

The American Golden Plover is abundant and 
well known to every one by its native name Chorlo 
throughout Southern Argentina, Its wild, clear notes 
are first heard about the last week in August ; and 
among the first comers many individuals are seen 
still wearing the nuptial dress. After their long 
journey from the Arctic regions they are lean and 
not worth shooting ; two months later they become 
excessively fat, and are then much appreciated by 
gourmets. But although so regular in their arrival 
they do not regularly visit the same localities every 
season ; the bird may be abundant in a place one 
year and scarce or absent altogether the next. Dur- 
ing the spring, from September to December, they 
prefer open plains with short grass and in the neigh- 
bourhood of wet or marshy ground ; at the end of 
December, when the giant thistle {Carduus mariana), 
which often covers large areas of country, has been 



i86 BIRDS OF LA PLATA 

burnt up by the sun and kfcwn to the ground^ they 
scatter about a great deal in flocks of from one to 
four or five hundred. At noon^ however, they all 
resort to a lagoon or marshy place containing vi^ater, 
congregating day after day in such numbers that 
they blacken the ground over an area of several acres 
in extent ; and at a distance of a quarter of a mile 
the din of their united voices resembles the roar of 
a cataract. As population increases on the pampas 
these stupendous gatherings are becoming more and 
more rare. Twenty-five years ago it was an excep- 
tional thing for a man to possess a gun, or to use 
one when he had it ; and if Chorlos were wanted, 
a gaucho boy, with a string a yard long with a ball 
of lead attached to each end, could knock down as 
many as he liked. I have killed them in this way 
myself, also with the bola perdida — a ball at the end 
of a long string thrown at random into a cloud of 
birds. 

The habits, flight, and language of the Golden 
Plover need not be spoken of here, as this bird has 
been so often and exhaustively described by North 
American ornithologists. The only peculiarity it 
possesses which I have not seen mentioned, is its 
faculty of producing a loud sound, as of a horn, when 
a few passing birds, catching sight of others of their 
kind on the ground below, descend violently and 
almost vertically to the earth with unmoving wings. 
This feat is, however, rarely witnessed ; and on the 
first occasion when I heard the sound high above 
me, and looked up to see half a dozen Chorlos rushing 



WINTER PLOVER 187 

down from the sky^ the sight almost took my breath 
away with astonishment. 

The Golden Plover appears to be most abundant 
on the pampas between the thirty-fourth and thirty- 
sixth parallels of latitude, but how far south its range 
extends has not yet been ascertained. The return 
migration begins early in March, and yet Mr. Barrows 
met with it in the neighbourhood of Bahia Blanca 
and on the Sierra de la Ventana from 8th February 
to 19th March. During most of this time, he says, it 
was abundant in flocks of from twenty to two hun- 
dred birds, which appeared to be moving uniformly 
south or south-west. 



WINTER PLOVER 

Eudromias modesta 

Above brownish cinereous ; frontal band and superciliary stripe 
white ; wings and central tail-feathers blackish ; lateral tail-feathers 
white, the inner ones with an imperfect black subterminal band ; 
beneath, throat cinereous, breast bright chestnut with a black band 
below ; belly white ; bill black, base of lower mandible yellowish ; 
feet brown ; length 7.5, wing 5.3 inches. Female similar. Young 
without the rufous chest. 

This species in its gait, flight, and general appearance 
closely resembles the American Golden Plover, but 
is smaller than that bird, and its sober upper plumage 
is unrelieved with flecks of golden colour. It breeds 
in South Patagonia and the Falklands, and migrates 
north in autumn, appearing on the pampas in April, 
and being met with there throughout the winter ; 



i88 BIRDS OF LA PLATA 

hence the vernacular name Chorlito de invierno 
(Little Winter Plover). In its winter dress the upper 
plumage is greyish drab colour ; the breast dark 
brown ; the belly white. It is shy and active in 
disposition^ has a very rapid flight, and is seen in 
flocks varying greatly in number, from a dozen to 
two or three hundred individuals. When feeding 
the birds scatter very widely, running swiftly over 
the ground in all directions. When on the wing it 
frequently utters its cry, which has not the mellow 
tone of the Golden Plover's note, but it is wonder- 
fully clear and far-reaching, and impresses the 
listener with its wildness and melancholy. 
Their return migration takes place in August. 



PATAGONIAN RINGED PLOVER 

Mgialitis falklandicus 

Above brown ; front white ; band across forehead and sides of head 
black, bordered with rufous ; wings black, with bright shafts and white 
edges to the base of some of the inner primaries ; central tail-feathers 
black, lateral white, with a more or less distinct subterminal blackish 
band, except on the outer pair ; beneath white, crossed by two broad 
blackish bands on the breast ; bill and feet black ; length 7, wing 5 
inches. Female similar. 

The pretty little Belted Plover inhabits the Falklands 
and South Patagonia, and migrates north in winter 
as far as Paraguay ; but it is not anywhere common, 
and is seldom seen in parties exceeding half a do2;en 
in number. It is extremely active, always preferring 
wet grounds to dry, and runs rapidly over the mud

SLENDER-BILLED PLOVER 189 

in search of food like a Tringa. Its only language 
is a low clicking note uttered when taking wing. 

Some individuals remain to breed as far north as 
the pampas of Buenos Ayres, Mr. Gibson says the 
nest is always placed near the water, and is a slight 
scrape in the ground lined with dry grass. The eggs 
are three in number, have black spots on an olive 
ground, and in shape resemble Lapwings' eggs. 

Durnford also found it breeding in the Chupat 
Valley in September 1877. 

There is a second species of Ringed Plover (Azara*s 
Ringed Plover, i^. collaris) which ranges over the 
whole of South America and was occasionally seen 
by me on migration, on the pampas. 



SLENDER-BILLED PLOVER 

Oreophilm ruficollis 

Above grey, varied with yellowish brown and striped with black on 
the back and wing-coverts ; front and superciliaries yellowish brown ; 
stripe through the eye blackish ; wings blackish with white shafts, 
their under surface white ; tail grey, with a black subterminal bar on 
the lateral feathers ; beneath grey ; throat rusty reddish ; below the 
breast a black band or patch ; bill dark, feet red ; length lo, wing 
6.5 inches. 

This pretty and singular Plover, with a bill like a 
Sandpiper, inhabits South Patagonia and the Falk- 
lands. In the autumn it migrates north, and during 
the cold season is found sparsely distributed through- 
out the Argentine States, and passes into Bolivia and 
Peru. On the pampas it is most abundant in April, 



igo BIRDS OF LA PLATA 

but most of the birds s$th. during that month are 
travellers to warmer latitudes. 

It is a shy and exceedingly active bird^ somewhat 
larger than the Golden Plover in size, and in the 
Plata district is usually called Chorlo canela, from 
the prevailing cinnamon-red of the plumage. It is 
distinguished in the family it belongs to by the great 
length of its straight, slender, probe-hke bill, unlike 
that of any other Plover ; and it also has other 
structural peculiarities, the toes being exceptionally 
short and thick, the frontal bone curiously modified, 
and the eyes enormously large, like those of a noc- 
turnal species. I do not think, however, that it 
migrates by night, as I have never heard its peculiar 
passage-cry after dark. A flock is usually composed 
of from a dozen to thirty individuals, and when on 
the ground they scatter widely, running more rapidly 
than any other Plover I am acquainted with. When 
they travel the flight is swift and high, the birds 
much scattered. They possess no mellow or ringing 
notes like other members of the Plover family ; on 
the ground they are silent, but when taking wing 
invariably utter a long, tremulous, reedy note, with a 
falling inflection, and usually repeated three or four 
times. The sound may be imitated by striking on the 
slackened stings of a guitar. This cry is frequently 
uttered while the birds are migrating. 

On the Rio Negro in Patagonia I observed this 
Plover only in the winter season ; but Durnford 
found it nesting in the valley of the Sengel in Chupat 
in the month of December. 



SEED-SNIPE 191 



SEED-SNIPE 

Thinocorus rumicivorus 

Above buffy brown, marbled and irregularly banded with black ; 
wing-feathers black, edged with white, external secondaries like the 
back ; tail black, broadly tipped with white, central rectrices like the 
back ; beneath white ; a broad line on each side of the throat uniting 
in the centre of the neck and expanding into a collar on the breast, 
black ; sides of neck greyish ; bill dark brown, feet yellow ; length 
6.5, wing 3.9 inches. Female similar but with only slight traces of 
black bar. 

This curious bird has the grey upper plumage and 
narrow, long, sharply-pointed wings of a Snipe, with 
the plump body and short, strong, curved beak of a 
Partridge, But the gallinaceous beak is not in this 
species correlated, as in the Partridges, with stout 
rasorial feet ; on the contrary, the legs and feet are 
extremely small and feeble, and scarcely able to 
sustain the weight of the body. When alighting the 
Seed-Snipe drops its body directly upon the ground 
and sits close like a Goatsucker ; when rising it 
rushes suddenly away with the wild, hurried flight 
and sharp, scraping alarm-cry of a Snipe. It is ex- 
clusively a vegetable feeder. I have opened the 
gizzards of many scores to satisfy myself that they 
never eat insects, and have found nothing in them 
but seed (usually clover-seed) and tender buds and 
leaves mixed with minute particles of gravel. 

These birds inhabit Patagonia, migrating north 
to the pampas in winter, where they arrive in April. 



192 BIRDS OF LA PLATA 

They usually go in flails of about forty or fifty 
individuals^ and fly rapidly, keeping very close 
together. On the ground, however, they are always 
much scattered, and are so reluctant to rise that 
they will allow a person to walk or ride through the 
flock without taking wing, each bird creeping into 
a little hollow in the surface or behind a tuft of grass 
to escape observation. During its winter sojourn 
on the pampas the flock always selects as a feeding- 
ground a patch of whitish argillaceous earth with a 
scanty, withered vegetation ; and here, when the 
birds crouch motionless on the ground, to which 
their grey plumage so closely assimilates in colour, 
it is most diflicult to detect them. If a person stands 
still, close to or in the midst of the flock, the birds will 
presently betray their presence by answering each 
other with a variety of strange notes, resembling the 
cooing of Pigeons, loud taps on a hollow ground, 
and other mysterious sounds, which seem to come 
from beneath the earth. 

In the valley of Rio Negro I met with a few 
of these birds in summer, but could not find their 
nests. 

Dumford, however, who found them breeding 
in Chupat at the end of October, tells us that 
the nest is a slight depression in the ground, some- 
times lined with a few blades of grass. ** The eggs 
have a pale stone ground-colour, very thickly but 
finely speckled with light and dark chocolate mark- 
ings ; they have a polished appearance, and measure 
1.3 by .8 inch.'* (Ibis, 1878, p. 403.) 



BRAZILIAN STILT 193 



BRAZILIAN STILT 

Himantopus brasiliensis 

White ; line behind each eye, nape, back of neck, interscapulium, 
and wings black ; a narrow white band divides the black neck from 
the black upper back ; bill black, feet orange ; length 14, wing 8.5 
inches. Female similar. 

This bird is resident and common in the Plata dis- 
trict, and is called in the vernacular Teru-realf also 
Zancudo (Stilt), It frequents marshes and lagoons, 
and wades in search of food in the shallow water 
near the margin. It is lively in its movements, and 
notwithstanding the great length of its legs has a 
pretty, graceful appearance on the ground. On the 
wing, however, it is seen at its best, the flight being 
remarkably swift and free, while the sharply-pointed 
glossy-black wings contrast finely with the snow- 
white plumage of the body, and the red legs stretched 
out straight behind have the appearance of a long, 
slender tail. Stilts are fond of aerial exercises, pur- 
suing each other with marvellous velocity through 
the air, so that a few moments after the spectator 
has almost lost sight of them in the sky above they 
are down again within a few yards of the surface. 
While pursuing each other they constantly utter 
their excited yelping cries, which in tone remind 
one of the musical barking of some hounds. 

The nest is made on the low ground close to the 
water, and consists merely of a slight lining of dry 
grass and leaves gathered in a small depression on 

N II 



194 BIRDS OF LA PLATA 

the surface ; the eggs ar^^ur in number, pyriform, 
dark olive colour spotted with brownish black, the 
spots being very thickly crowded at the large end. 
During incubation the male keeps guard and utters 
a warning note on the appearance of an enemy, 
whereupon the female quits the nest. They also 
counterfeit lameness to draw a person from the 
neighbourhood of the eggs or young, but in a manner 
peculiar to this species ; for owing to the great 
length of their legs they cannot drag themselves 
along the ground, as Ducks, Plover, Partridges, and 
other birds do. Placing themselves at a distance of 
forty or fifty yards from the intruder, but with breast 
towards him, they flutter about a foot above the 
ground, their long legs dangling under them, and 
appear as if struggling to rise and repeatedly falling 
back. If approached they slowly retire, still fluttering 
just above the grass and without making any sound. 
After the young birds are able to fly they remain 
with the parents until the following spring ; and 
sometimes two or three families associate together, 
raising the number of the flock to fifteen or twenty 
birds. The young have a sharp, querulous cry of 
two notes ; the plumage is brown and pale grey ; 
the eyes black. After nine or ten months the adult 
plumage is acquired, not by moulting, but by a 
gradual change in the colours of the feathers. By 
the same gradual process the eye changes from black 
to crimson, the outer edge of the iris first assuming 
a dull reddish colour, which brightens and widens 
until the whole iris becomes of a vivid red. 



PARAGUAY SNIPE 195 



PARAGUAY SNIPE 

Callinago paraguaix 

Above brown^ striped and barred with black and pale fulvous ; 
wings dark cinereous edged with white ; tail of sixteen rectrices, of 
which the outer pair are pin-shaped ; beneath white, breast marbled 
with blackish and brown ; length 10.5, wing 9,1 inches. 

This familiar bird, called Agachona in the vernacular, 
from its habit of crouching close to the ground to 
escape observation when approached, is abundant in 
the Plata district and resident, although its sudden 
and total disappearance from all the open wet places 
where it is common in the winter gives one the 
impression that it is migratory. The bird, however, 
only retires to breed in the extensive lonely marshes ♦ 
The nest is a slight depression on the moist ground 
close to the water, and lined with a little withered 
grass. The eggs are four, pear-shaped, and spotted 
with black on an olive-coloured ground. 

After the summer heats are over Snipes suddenly 
appear again all over the country, and at this season 
they are frequently met with on the high and dry 
grounds among the withered grass and thistles. In 
favourable wet seasons they sometimes collect in 
large flocks, numbering not less than five or six 
hundred birds, and a flock of this kind will occasion- 
ally remain in one spot for several months without 
breaking up. They usually frequent an open spot of 
level ground where the water just covers the roots 
of the short grass ; here the birds keep close together 



ia6 BIRDS OF LA PLATA 

while feeding and arc visihi^ from a long distance ; 
but they become extremely wary, all raising their 
heads in a very un-Snipe-like manner at the slightest 
alarm, and taking flight with the readiness of Wild 
Ducks. These flocks are, however, not often met 
with. Usually the Snipe is a solitary bird, crouches 
close when approached, and springs up suddenly 
when almost trodden on, loudly uttering its sharp 
scraping alarm-cry ; after rising to a considerable 
height, flying in a wild erratic manner, it returns 
suddenly to' the earth, often dropping into the grass 
within twenty yards of the spot it rose from. 

It is indeed curious to see how these habits, char- 
acteristic of the Snipes all over the world, are so 
completely laid aside when the birds associate in 
large flocks. 

Early and late in the day many individuals are 
usually on the wing engaged in their aerial pastimes, 
the singular grinding or scythe-whetting sounds 
caused by their feathers in their violent descent from 
a great height being distinctly audible at a distance 
of nearly a mile. It is heard throughout the winter 
at all hours of the day in mild, damp weather, and 
on moonlight nights often until after midnight. 



ARGENTINE PAINTED SNIPE 197 



ARGENTINE PAINTED SNIPE 

Rhynchxa semicollaris 

Above dark brown ; head black, with a central and two lateral 
longitudinal bands of buffy white ; wings ashy blackish, spotted with 
buffy white and barred with black ; coverts with large oval spots of 
clear white ; beneath, throat and breast dark brownish, with a con- 
spicuous white neck-collar on each side ; belly white, flanks tinged 
with buffy ; bill greenish, reddish at tip ; feet flesh-colour ; length 
8, wing 4.1 inches. Female similar, but shghtly larger and more 
brightly coloured. 

In the Argentine provinces this bird is called Dormildn 
(Sleepy-head), in allusion to its dull habits, which 
are like those of a nocturnal species* It passes the 
daylight hours concealed in dense reed-beds, rising 
only when almost trodden on ; the flight is feeble 
and erratic, the rapid wing-flutterings alternating 
with intervals of gliding, and after going a short 
distance the bird drops again like a Rail into the 
rushes ♦ From its behaviour on the ground, also in 
flying, when it appears dazed with the light, I have 
no doubt that it is altogether nocturnal or crepuscular 
in its habits. It is solitary and resident, and may be 
met with in small numbers in every marsh or stream 
in the Plata district, where its favourite reed-beds 
afford it cover. It appears to have no cry or note 
of any kind, for even when frightened from its nest 
and when the eggs are on the point of hatching it 
utters no sound* The eggs never exceed two in 
number, and are placed on the wet ground, often 
without any lining, among the close grass and herbage 



igS BIRDS OF LA PLATA 

near the water. They are oblong and bluntly pointed 
at the smaller end, and have a white ground colour, 
but so densely marked and blotched with black that 
in some cases they appear to be almost wholly of 
that colour, or like black eggs flecked with white. 



PECTORAL SANDPIPER 

Tringa maculata 

Above brown, varied with black ; superciliaries whitish ; rump and 
middle upper tail-coverts white ; beneath white ; neck and breast 
greyish streaked with blackish ; length 8.5, wing 5.1 inches. Female 
similar. 

The Pectoral Sandpiper is a well-known North- 
American species that visits the south during migra- 
tion. It breeds abundantly in Alaska, and descends 
in winter through Central and South America to 
Chili and Patagonia. Durnford found it abundant 
about the salt-lagoons of Chupat. Near the end of 
August it begins to arrive in La Plata, usually in 
very small flocks or singly ; and among these first 
comers there are some young birds so immature, 
with threads of yellow down still adhering to the 
feathers of the head and altogether weak in appear- 
ance, that one can scarcely credit the fact that so soon 
after being hatched they have actually performed 
the stupendous journey from the northern extremity 
of the North American continent to the Buenos- 
Ayr ean pampas. 

This species differs from other Sandpipers in 



GREATER YELLOWSHANKS 199 

being much more solitary and sedentary in its ways, 
feeding for hours in one spot, and in its Snipe-like 
habit of sitting close when approached and remaining 
motionless watching the intruder ; also in its lan- 
guage, its low, soft, tremulous cry when flying being 
utterly unlike the sharp and clicking sounds emitted 
by other species. During the hot months, when 
water begins to fail, they occasionally congregate in 
flocks, sometimes as many as two or three hundred 
individuals being seen together ; but at all times 
it is more usual to see them in small parties of half 
a dozen or singly. 

Two other well-known Arctic- American species of 
Tringa are annual visitants to Argentina : — Baird's 
Sandpiper, T. hairdi^ and Bonaparte's Sandpiper, 
r. fuscicollis* 



GREATER YELLOWSHANKS 

Totanus melanoleucm 

Above brownish grey spotted with white ; rump nearly white ; 
beneath white ; throat and neck with black streaks ; bill blacky feet 
yellow ; length 14, wing 7.5 inches. Female similar. 

The Greater Yellowshanks is best known as an 
Arctic-American species, descending south during 
migration, and arriving in La Plata at the end of 
September or early in October, singly or in pairs, 
and sometimes in small flocks. Without ever being 
abundant the bird is quite common, and one can 



200 BIRDS OF LA PLATA 

seldom approach a pool or marsh on the pampas 
without seeing one or more individuals wading near 
the margin^ and hearing their powerful alarm-cry 
— a long, clear note repeated three times. 

These summer visitors leave us in March, and 
then, oddly enough, others arrive, presumably from 
the south to winter on the pampas, and remain from 
April to August. Thus, notwithstanding that the 
Yellowshanks does not breed on the pampas, we have 
it with us all the year round, Durnford's obser- 
vations agree with mine, for he says that the bird 
is found throughout the year near Buenos Ayres ; 
and Mr. Barrows writes that this species ** occurs 
every month in the year (at Concepcion in Entrerios), 
but in increased numbers during August, September, 
October, and November.** 

The Lesser Yellowshanks, Totanus flavipeSf is 
also a common species, a visitor from Arctic America, 
in Argentina from September to April. Many non- 
breeding individuals are also found during the other 
months of the year. In habits, language, colour, and 
— except in size — in its entire appearance it closely 
resembles the Greater Yellowshanks ; and the two 
species, attracted or deceived by this likeness, are 
constantly seen associating together. 



SOLITARY SANDPIPER 201 

SOLITARY SANDPIPER 

Rhyacophilus solitarius 

Middle toe nearly as long as tarsus. Above dark olivaceous grey, 
with blacker markings and slightly speckled with white ; upper tail- 
coverts blackish, barred with white ; tail white with blackish bars ; 
beneath white ; sides of neck and breast streaked and barred with 
dusky grey ; under wing-coverts blackish, barred with white ; length 
8.5, wing 5 inches. Female similar. 

The well-known and well-named Solitary Sandpiper 
arrives later than the other birds of its family in La 
Plata, and differs greatly from them in its habits, 
avoiding the wet plains and muddy margins of 
lagoons and marshes where they mostly congregate, 
and making its home at the side of a small pool well 
sheltered by its banks, or by trees and herbage, and 
with a clear margin on which it can run freely. As 
long as there is any water in its chosen pool, though 
it may be only a small puddle at the bottom of a 
ditch, the bird will remain by it in solitary content- 
ment. When approached it runs rapidly along the 
margin, pausing at intervals to bob its head, in which 
habit it resembles the Totanus or Yellowshanks, and 
emitting sharp little clicks of alarm. Finally, taking 
flight, it utters its peculiar and delightful cry, a long 
note thrice repeated, of so clear and penetrating a 
character that it seems almost too fine and bright 
a sound even for so wild and aerial a creature as a 
bird. 

The flight is exceedingly rapid and wild, the bird 
rising high and darting this way and that, uttering 



202 BIRDS OF LA PLATA 

its piercing trisyllabic cr^ne whole time, and finally, 
dashing downwards, it suddenly drops again on to 
the very spot from which it rose. 

I was once pleased and much amused to discover 
in a small sequestered pool in a wood, well sheltered 
from sight by trees and aquatic plants, a Solitary 
Sandpiper living in company with a Blue Bittern. 
The Bittern patiently watched for small fishes, and 
when not fishing dozed on a low branch overhanging 
the water ; while its companion ran briskly along 
the margin snatching up minute insects from the 
water. When disturbed they rose together, the 
Bittern with its harsh, grating scream, the Sandpiper 
daintily piping its fine bright notes — a wonderful 
contrast ! Every time I visited the pool afterwards 
I found these two hermits, one so sedate in manner, 
the other so lively, living peacefully together. 



BARTRAM'S SANDPIPER 

Actitura bartramius 

Above blackish, feathers edged with yellowish brown ; rump black ; 
wing-coverts yellowish brown, barred with black ; primaries blackish ; 
beneath white ; breast and flanks ochraceous, spotted and barred with 
black ; under surface of wings barred with white and black ; bill 
yellowish, tip black ; feet yellow ; length lo, wing 6.3 inches. Female 
similar. 

Bartram^s Sandpiper, a Sandpiper with the habits 
of a Plover, is a widely-distributed North American 
species, its breeding area extending over a large 
portion of the United States, where it is known as 



BARTRAM'S SANDPIPER 203 

the Upland Plover* The people of that country have 
been paying it a good deal of attention of late ; they 
have discovered that it is a charming bird, and at 
the same time that during the last three or four 
decades their gunners have almost extirpated it* 
They fear that it is going the way of the Passenger 
Pigeon, the Pinnated Grouse, the Carolina Parro- 
keet, the Ivory-billed Woodpecker, and, I believe 
we must now add, the Esquimo WhimbreL 

This species differs from its fellow-migrants of 
the same family from the north to Argentina in its 
wide and even distribution over all that portion of 
the pampas where the native coarse grasses which 
once covered the country have disappeared, an area 
comprising not less than 50,000 square miles* It 
begins to arrive as early as September, coming singly 
or in small parties of three or four ; and, extra- 
ordinary as the fact may seem when we consider the 
long distance the bird travels, and the monotonous 
nature of the level country it uses as a '' feeding 
area,^' it is probable that every bird returns to the 
same spot year after year ; for in no other way could 
such a distribution be maintained, and the birds 
appear every summer evenly sprinkled over so 
immense a surface* 

On the pampas the bird is called Chorlo solo, 
on account of its solitary habit, but more com- 
monly BatitUf an abbreviation of the Indian name 
MbatuituL In disposition it is shy, and prefers 
concealment to flight when approached, running 
rapidly away through the long grass or thistles, or 



204 BIRDS OF LA PLATA 

concealing itself behina a tussock until the danger 
is past, or often, where the herbage is short, crouching 
on the ground like a Snipe. It runs swiftly and 
pauses frequently ; and while standing still with head 
raised it jerks its long tail up and down in a slow 
measured manner. When driven up it springs aloft 
with a sudden wild flight, uttering its loud mellow- 
toned cry, composed of three notes, strongly accented 
on the first and last ; and sometimes, when the bird 
is much alarmed, the first note is rapidly reiterated 
and becomes a bubbling sound like that of the 
European Cuckoo, but much more musical. After 
flying a very short distance it drops to the ground 
again, agitating its wings in a tremulous manner as 
it comes down. And sometimes after alighting it 
continues standing motionless for several seconds 
with the wings stretched up vertically. These wing 
motions and other pretty gestures give it a very 
attractive appearance. In its skulking habits, and 
reluctance to fly, it is more like a Rail than a Snipe. 
It also, Rail-like, frequently alights on trees and 
fences, a habit I have not remarked in any other 
Limicohne species. 

It inhabits the pampas from September until 
March ; but early in February the great return 
migration begins, and then for two months the 
mellow cry of the Batitu is heard far up in the 
sky, at all hours, day and night, as the birds wing 
their way north. In some seasons stragglers are 
found throughout the month of April, but before 
the winter arrives not one is left. 



BUFF-BREASTED SANDPIPER 205 



BUFF-BREASTED SANDPIPER 

Tryngites mfescens 

Above dark brownish black, each feather widely edged with buff; 
wings blackish, narrowly tipped with white, the inner half of the inner 
web whitish reticulated with black; tail blackish, the outer rectrices 
lighter, each with subterminal black crescent and white terminal 
edge ; beneath buff, darker on the throat and breast, and edged with 
whitish, lighter on flanks and belly; under primary-coverts barred 
and reticulated with black, Uke the inner web of the primaries, 
and forming a marked contrast with the rest of the under surface of 
the wing, which is pure white ; length 7-7. wing 5-3 inches. Female 
similar. 

This species is also an annual visitor to the pampas 
from the Arctic regions where it breeds. It begins 
to arrive, usually in small bodies, early in the month 
of October ; and during the summer is seldom met 
with in flocks of any si2;e on the pampas, but is usually 
seen on the dry, open ground associating in small 
numbers with the Golden Plover, the Whimbrel, 
and other northern species. I however think it 
probable that it travels farther south than its fellow- 
migrants from North America, and has its principal 
feeding-grounds somewhere in the interior of Pata- 
gonia ; also that its northern journey takes place 
later than that of other species. In some seasons I 
have observed these birds in April and May, in 
flocks of two to five hundred, travelling north, flock 
succeeding flock at intervals of about fifteen minutes, 
and continuing to pass for several days. 



2o6 BIRDS OF LA PLATA 

HUDSONIAN GODWIT 

Limosa hsemastica 

In summer: Above dark brownish black, mixed on the head with 
longitudinal streaks of whitish, on the neck with pale chestnut, and 
with many of the feathers of the back spotted or edged with pale 
chestnut ; wings and tail blackish, the upper half of the inner webs 
of the primaries and secondaries, the basal part of the outer rectrices, 
and a broad band across the upper tail-coverts pure white ; beneath, 
cheeks and throat whitish, becoming pale chestnut on the neck, longi- 
tudinally striped with blackish ; rest of under surface deeper chestnut, 
transversely barred with blackish. In winter: Above uniform dull 
brownish ; head, neck, and under surface dirty white or pale buff ; 
length 14.3, wing 8.5 inches. 

The Hudsonian Godwit, Mr. Seebohm tells us, 
** breeds on the tundras of North America north 
of the forest-growth, from Alaska to Baffin's Bay, 
but is rare at the western extremity of its range." In 
winter it goes far south, like most of the other Grallx* 

Durnford found it '' common from April to Sep- 
tember about the lagoons and arroyos to the south 
of Buenos Ayres '' ; and states that in habits it much 
resembles the Bar-tailed Godwit of Europe {Limosa 
lapponica) . He also met with it in Chupat, and obtained 
two specimens there on the 13th of November, 1876. 

I have met with it in flocks during the summer of 
the Southern Hemisphere, and these birds, as well 
as those obtained by Durnford, were undoubtedly 
visitors from the north ; but invariably small flocks 
of half a dozen to thirty birds begin to appear on the 
pampas in April, and remain there, as Durnford 
says, until September, when the northern migrants 
are nearly due. These individuals must therefore 



ESQUIMO WHIMBREL 307 

breed near the extremity, or beyond the extremity, 
of South America* It is very curious, to say the 
least of it, that the Arctic and Antarctic regions of 
America should possess the same species, and that, 
at opposite seasons of the year, it should winter in 
the same district, so far from the breeding-place of 
one set of individuals, and so near to that of the 
other ! Captain Abbott observed the Hudsonian 
Godwit in the Falkland Islands in flocks in the 
month of May (see Ibis, 1861, p, 156). These could 
not have been Alaska birds, but were no doubt 
southern breeders on their way north, for that they 
could winter so far south seems incredible. 



ESQUIMO WHIMBREL 

Numenim borealis 

Above dark brown, each feather edged or spotted with pale buff or 
dirty white, becoming most strongly marked on the rump and upper 
tail-coverts ; wings uniform dusky brownish, narrowly edged with 
white ; tail buffy brown, transversely barred with dusky ; beneath, 
throat white ; rest of under surface pale buff, with more or less 
V-shaped dusky markings on the breast, flanks, and under tail-coverts ; 
axillaries and under wing-coverts pale chestnut, transversely barred 
with dusky ; length ii.6, tail 8.14 inches. Female similar. 

The Esquimo Whimbrel, which, as Mr. Seebohm 
tells us, may be distinguished from all its congeners 
by having scarcely any traces of bars on its prim- 
aries and by the back of the tarsus being covered 
with hexagonal reticulations, migrates from the 
tundras of North America, where it breeds, to the 
southern extremity of South America. 



2o8 BIRDS OF LA PLATA 

Mr. Barrows noted its^rst arrival at Concepcion in 
Entrerios on gth September, 1880, '' in large flocks/' 
After the middle of October not one was seen. 

The same excellent observer saw it almost daily 
on the pampas between Azul and Bahia Blanca, '' in 
company with the Golden Plover and Bartram's 
Sandpiper, until late in February." 

From the 8th to the loth of October, 1877, Durn- 
ford saw large flocks of this Whimbrel in the Chupat 
valley flying south, and obtained two specimens. 
Capt. Packe and Capt. Abbott both procured examples 
in the Falkland Islands. 

The Esquimo Whimbrel was common enough in 
its season on the pampas in my day, appearing in 
September to October in small flocks of thirty or 
forty to a hundred or more, and often associating 
with the Golden Plover ; but, as I now hear from 
the authorities of the Smithsonian Institution at 
Washington, it is practically extinct. 



BLACK-TAILED SKIMMER 

Rhynchops melanura 

Above brownish black ; forehead and wing-band white ; tail black ; 
beneath white ; bill, apical half black, basal half orange ; feet red ; 
length 19, wing 15 inches. Female similar. 

The Black-tailed Skimmer, which is common on the 
coasts of Brazil, migrates south in spring, following 
the course of the Plata river in its journey, and 



BLACK-TAILED SKIMMER 209 

appearing in pairs or small flocks in the neighbour- 
hood of Buenos Ayres during the month of October, 
Its chief breeding-ground is on the extensive mud- 
banks and islets at Bahia Blanca on the Atlantic 
coast. The return migration occurs in March. 

Darwin met with the Scissor-bill during his ex- 
cursion up the Parana in October, 1833, and speaks 
of it as follows {Nat. Journ.t p. 161) : 

** I here saw a very extraordinary bird, called the 
Scissor-beak (Rhynchops nigra)* It has short legs, 
web feet, extremely long-pointed wings, and is of 
about the size of a Tern. The beak is flattened 
laterally, that is in a plane at right angles to that of 
a Spoonbill or Duck. It is as flat and elastic as 
an ivory paper-cutter, and the lower mandible, dif- 
ferent from every other bird, is an inch and a half 
longer than the upper. I will here detail all I know 
of the habits of the Scissor-beak. It is found both on 
the east and west coasts, between latitudes 30 and 
45, and frequents either salt or fresh water. The 
specimen now at the Zoological Society was shot at 
a lake near Maldonado, from which the water had 
been nearly drained, and which in consequence 
swarmed with small fry. I there saw several of these 
birds, generally in small flocks, flying backwards 
and forwards, close to the surface of the lake. They 
kept their bills wide open, and with the lower man- 
dible half buried in the water. Thus skimming the 
surface, they ploughed it in their course ; the water 
was quite smooth, and it formed a most curious 
spectacle to behold a flock, each bird leaving its 

O II 



2IO BIRDS OF LA PLATA 

narrow wake on the mi||i)r-like surface. In their 
flight they frequently twist about with extreme 
rapidity, and so dexterously manage, that with their 
projecting lower mandible they plough up small 
fish, which are secured by the upper half of their 
scissor-like bilh This fact I repeatedly saw as, like 
Swallows, they continued to fly backwards and 
forwards close before me. Occasionally, when leav- 
ing the surface of the water, their flight was wild, 
irregular, and rapid ; they then also uttered loud, 
harsh cries. When these birds are fishing, the length 
of the primary feathers of the wings is seen to be 
quite necessary, in order to keep the latter dry. 
When thus employed, their forms resemble the 
symbol by which many artists represent marine birds. 
The tail is much used in steering their irregular course. 
'' These birds are common far inland along the 
course of the Rio Parana ; it is said they remain 
during the whole year and breed in the marshes. 
During the day they rest in flocks on the grassy 
plains, at some distance from the water. Being at 
anchor, as I have said, in one of the deep creeks 
between the islands of the Parana, as the evening 
drew to a close one of these Scissor-beaks suddenly 
appeared. The water was quite still, and many 
little fish were rising. The bird continued for a 
long time to skim the surface, flying in its wild and 
irregular manner up and down the narrow canal, 
now dark with the growing night and the shadows 
of the overhanging trees. At Monte Video I observed 
that some large flocks during the day remained on 



DOMINICAN GULL 211 

the mud-banks at the head of the harbour, in the 
same manner as on the grassy plains near the Parana ; 
and every evening they took flight direct to seaward. 
From these facts I suspect that the Rhynchops 
generally fishes by night, at which time many of the 
lower animals come most abundantly to the surface, 
M, Lesson states that he has seen these birds open 
the shells of the Mactrx^ buried in the sand-banks 
on the coast of Chili ; from their weak bills, with 
the lower mandible so much produced, their short 
legs and long wings, it is very improbable that this 
can be a general habit/' 



DOMINICAN GULL 

Larus dominicanus 

Mantle brownish-black ; primaries black, with white tips, and a 
subapical patch in old birds ; rest of plumage white ; bill yellow, 
orange at angle of lower mandible ; legs and feet olive ; length 22, 
wing 18 inches. 

The Dominican Gull, which belongs to the same 
section of the group as the well-known Black-backed 
Gulls of Europe and closely resembles our Great 
Black-backed Gull, is common throughout the Plata 
district in winter, from April to August, During the 
summer months it confines itself to the Atlantic 
coast, and breeds in large numbers in the neigh- 
bourhood of Bahia Blanca, on the extensive sand- 
banks and mud-flats there ; and in other suitable 
localities further south, Durnford found it nesting at 
Tombo Point, sixty miles south of the Chupat river. 



212 BIRDS OF LA PLATA 

At the approach of coMT weather the Dominican 
Gulls leave the sea-shore and wander inland and 
northward. At this season they are almost exclu- 
sively flesh-eaters, with a preference for fresh meat ; 
and when the hide has been stripped from a dead 
cow or horse they begin to appear, vulture-like, 
announcing their approach with their usual long, 
hoarse sea-cries, and occasionally, as they circle about 
in the air, joining their voices in a laughter-like 
chorus of rapidly repeated notes. Their winter 
movements are very irregular ; in some seasons 
they are rare, and in others so abundant that they 
crowd out the Hooded Gulls and Carrion-Hawks 
from the carcase ; I have seen as many as five to six 
hundred Dominicans massed round a dead cow. 



ARGENTINE BLACK-HEADED GULL 

Larus maculipennis 

Head and nape brownish-black (in breeding dress) ; tail and under- 
parts white ; mantle pale grey ; primaries black or dark grey, tipped 
with white, and with large elongated white patches on the outer portions 
of first to fifth, followed by a subapical black bar (in L. glaucodes the 
lower portion is white) ; underwing pale grey ; bill, legs, and feet 
blood-red ; length 17, wing 11.5 inches. 

This common Black-headed Gull is found through- 
out the Argentine country, down to Chupat in Pata- 
gonia, and is exceedingly abundant on the pampas 
of Buenos Ayres, where it is simply called Gaviota 
(Gull). In the month of October they congregate 
in their breeding-places — extensive inland marshes. 



BLACK-HEADED GULL 213 

partially overgrown with rushes* The nests are 
formed of weeds and rushes, placed just above the 
water and near together, several hundreds being 
sometimes found within an area of less than one 
quarter of an acre. The eggs are four in number, 
large for the bird, obtusely pointed, of a pale clay- 
colour, thickly spotted at the big end and sparsely 
on the other parts with black. 

Every morning at break of day the Gulls rise up 
from their nests and hover in a cloud over the marsh, 
producing so great a noise with their mingled cries 
that it can be heard distinctly at a distance of two 
miles. The eggs are considered a great delicacy, 
resembling those of the Plover in taste and appear- 
ance, and are consequently much sought after, so 
that when the locality near which a gullery is situated 
becomes inhabited the birds have no chance of 
rearing their young, as the boys in the neighbour- 
hood ride into the marsh every morning to gather 
the eggs. The Gulls are, however, very tenacious 
of their old breeding-places, and continue even after 
years of persecution to resort to them. 

The young birds are of a pale grey colour, mottled 
with dull brown, and have a whining, querulous cry. 
The plumage becomes lighter, through the autumn 
and winter, but it is not until the ensuing summer, 
when the dark brown nuptial hood is assumed, that 
the young birds acquire the perfect plumage — soft 
grey-blue above, and the white bosom with its lovely 
pink blush. 

As soon as the young are able to fly the breeding- 



214 BIRDS OF LA PLATA 

place is forsaken, the whoie concourse leaving in a 
body, or scattering in all directions over the sur- 
rounding country ; and until the following summer 
their movements depend entirely on food and water. 
If the weather is dry the Gulls disappear altogether ; 
and if grasshoppers become abundant the country 
people wish for rain to bring the Gulls, When it 
rains then the birds quickly appear, literally from the 
clouds, and often in such numbers as to free the 
earth from the plague of devastating insects. It is a 
fine and welcome sight to see a white cloud of birds 
settle on the afflicted district ; and at such times their 
mode of proceeding is so regular that the flock well 
deserves the appellation of an army. They sweep 
down with a swift, graceful flight and settle on the 
earth with loud, joyful cries, but do not abandon 
the order of attack when the work of devouring has 
begun. The flock often presents a front of over a 
thousand feet, with a depth of sixty or seventy feet ; 
all along this line of battle the excited cries of the 
birds produce a loud, continuous noise ; all the birds 
are incessantly on the move, some skimming along 
the surface with expanded wings, others pursuing 
the fugitives through the air, while all the time the 
hindmost birds are flying over the flock to alight in 
the front ranks, so that the whole body is steadily 
advancing, devouring the grasshoppers as it pro- 
ceeds. When they first arrive they seem ravenously 
hungry, and after gorging themselves they fly to 
the water, where after drinking they cast up their 
food and then go back to renew the battle. 



BLACK-HEADED GULL 215 

In spring these Gulls come about the farms to 
follow the plough, filling the new-made furrows 
from end to end, hovering in a cloud over the plough- 
man's head and following at his heels, a screaming, 
fighting multitude, Wilson's expression in describing 
a northern species, that its cry ** is like the excessive 
laugh of a negro,'' is also descriptive of the language 
of our bird. Its peculiar cry is lengthened at will 
and inflected a hundred ways, and interspersed 
with numerous short notes like excited exclamations. 
After feeding they always fly to the nearest water to 
drink and bathe their feathers, after which they 
retire to some open spot in the neighbourhood where 
there is a carpet of short grass. They invariably sit 
close together with their bills toward the wind, and 
the observer will watch the flock in vain to see one 
bird out of this beautiful order. They do not stand 
up to fly, but rise directly from a sitting posture. 
Usually the wings are flapped twice or thrice before 
the body is raised from the ground. 

In some seasons in August and September, after 
a period of warm, wet weather, the larvae of the large 
horned beetle rise to the surface, throwing up little 
mounds of earth as moles do ; often they are so 
numerous as to give the plains, where the grass has 
been very closely cropped, the appearance of being 
covered with mud. These insects afford a rich harvest 
to the Spur-winged Lapwing {Vanellus cayennensis), 
which in such seasons of plenty are to be seen all 
day diligently running about, probing and dis- 
lodging them from beneath the fresh hillocks. The 



2i6 BIRDS OF LA PLATA 

Gulls^ unprovided with a Robing beak^ avail them- 
selves of their superior cunning and violence to rob 
the Lapwings ; and I have often watched their pro- 
ceedings for hours with the greatest interest. Hun- 
dreds of Lapwings are perhaps visible running 
busily about on all sides ; near each one a Gull is 
quietly stationed, watching the movements of its 
intended dupe with the closest attention. The 
instant a great snow-white grub is extracted the 
Gull makes a rush to sei^e it, the Lapwing flies, and 
a violent chase ensues. After a hundred vain doub- 
lings the Plover drops the prize, and slopes toward 
the earth with a disappointed cry ; the pursuer 
checks his flight, hovers a moment watching the 
grub fall, then drops down upon it, gobbles it up, 
and hastens after the Lapwing to resume his watch» 
Many of these Gulls haunt the estancias to feed 
on the garbage usually found in abundance about 
cattle-breeding establishments. When a cow is 
slaughtered they collect in large numbers and quarrel 
with the domestic poultry over the offal. They are 
also faithful attendants at the shepherd*s hut ; and 
if a dead lamb remains in the fold when the flock 
goes to pasture they regale on it in company with 
the Chimango. The great saladeroSf or slaughter- 
grounds, which were formerly close to Buenos Ayres, 
were also frequented by hosts of these neat and 
beautiful scavengers. Here numbers were seen hover- 
ing overhead, mingling their excited screams with 
the bellowing of half-wild cattle and the shouts of 
the slaughterers at their rough work ; and at intervals, 



GREAT GREBE 217 

wherever a little space is allowed them^ dropping 
down to the ground^ which reeked with blood and 
offal^ greedily snatching up whatever morsels they 
could seize on, yet getting no stain or speck on their 
delicate dress of lily-white and ethereal blue. 

On the open pampas their curiosity and anger 
seem greatly excited at the appearance of a person 
on foot ; no sooner has the Gull spied him than it 
sweeps toward him with a rapid flight, uttering loud, 
indignant screams that never fail to attract all of its 
fellows within hearing distance. These all pass and re- 
pass, hovering over the pedestrian's head, screaming 
all the time as if highly incensed, and finally retire, 
joining their voices in a kind of chorus and waving 
their wings upwards in a slow, curious manner ; but 
often enough, when they are almost out of sight, they 
suddenly wheel about and hurry back screaming, 
with fresh zeal, to go through the whole pretty but 
annoying performance again. 



GREAT GREBE 

Mchmophorus major 

Above blackish ; occipital crest divided, bronzy black ; wide bar 
across the wing white ; beneath white ; chin dark ashy ; neck, breast, 
and sides of belly (in adult) more or less red ; bill yellowish, feet dark ; 
length 21, wing 8 inches. 

This Grebe is called in the vernacular Macas 
cornudo — the first word being the Indian generic 
name for the Grebes, while cornudo signifies homed, 
from the bird's habit of erecting, when excited, the 



2i8 BIRDS OF LA PLATA 

feathers of the nape in^e form of a horn. The 
species is found throughout Eastern Argentina, from 
its northern Hmits to Central Patagonia, where 
Dumford found it common and resident. On the 
Rio Negro I found it abundant, and it was formerly 
just as common along the Plata river, but owing to 
its large size and the great beauty of its lustrous 
under-plumage it is very much sought after and is 
becoming rare. 

It is impossible to make this Grebe leave the 
water, and when discovered in a small pool it may 
be pursued until exhausted and caught with the 
hand ; yet it must occasionally perform long journeys 
on the wing when passing from one isolated lake to 
another. Probably its journeys are performed by night. 

There is little diversity in the habits of Grebes, 
and only once have I seen one of these birds acting 
in a manner which seemed very unusual. This Grebe 
was swimming about and disported itself in a deep, 
narrow pool, and showed no alarm at my presence, 
though I sat on the margin within twenty-five yards 
of it. I saw it dive and come up with a small fish 
about three inches long in its beak ; after sitting 
motionless for a little while, it tossed the fish away 
to a considerable distance with a sudden jerk of its 
beak, and then at the instant the fish touched the 
water it dived again. Presently it emerged with 
the same fish, but only to fling it away and dive 
as before ; and in this way it released and recap- 
tured it about fifteen times, and then, tired of 
play^ dropped it and let it escape. 



TATAUPA TINAMU 219 

Mr* Gibson has the following note on the breeding 
habits of the Great Grebe^ as observed at Ajo, near 
the mouth of Rio de La Plata : ** P* major breeds 
about the end of August, placing its nest in the 
thickest rushes of the swamp* The nest, built of 
wet water-weeds, is raised just above the level of the 
water ; and I have twice seen the sitting bird hastily 
draw some weeds over the eggs before leaving them, 
on my approach. The clutch consists of three ; and 
these are of the usual Grebe colour, generally much 
soiled and stained/^ 

There are four more species of Grebe in Argen- 
tina : the Bright-cheeked Grebe, Podiceps cali- 
parsuSf confined to southern S. America ; Holland's 
Grebe, Podiceps rollandi, also confined to the south 
of the continent ; the American Dabchick, Tachy- 
baptes dominicus, inhabiting Central and S. America ; 
and the Thick-billed Grebe, Podilymhus podiceps^ 
found in both North and South America. 



TATAUPA TINAMU 

Crypturus tataupa 

Above chestnut brown ; head and neck dark cinereous ; beneath 
cinereous ; throat white ; middle of belly white ; flanks and crissum 
varied with undulating bars of black and white ; bill yellowish, feet 
dark ashy ; length lo, wing 5.2 inches. Female similar. 

The Tataupa Tinamu was first described by Azara 
as an inhabitant of Paraguay, whence it extends into 
the northern provinces of the Argentine Republic. 



220 BIRDS OF LA PLATA 

White obtained specim^s among the undergrowth 
in the dense forests of Campo Colorado, near Oran, 
and Durnford also met with it near Salta. 

To Azara's interesting account of the Tataupa's 
habits nothing has been recently added. He says 
that this species inhabits woods and thickets, and 
also approaches houses where it finds cover — hence 
the Guarani name, which means a domestic bird, 
or of the house. It lays four eggs of a fine purple 
colour ; and when driven from the nest flutters 
along the ground, feigning lameness. It sings all 
the year round, and for power and brilliance of 
voice is pre-eminent among this class of birds. After 
the first note of its curious song there is an interval 
of eight seconds of silence ; then the note is repeated 
with shorter and shorter intervals, until, becoming 
hurried, it runs into a trill, followed by a sound 
which may be written chororOf repeated three or 
four times. When sitting close it tips forward, 
pressing its breast on its legs, so that the rump is 
raised higher than the back, and opening the term- 
inal feathers of the body, it spreads them in a semi- 
circle over the back as if to conceal itself beneath 
them, and when looked at from behind nothing is 
visible except this fan of feathers. The feathers are 
concave with points inclining upward, and when thus 
disposed have a singular and beautiful appearance. 



RUFOUS TINAMU 231 



RUFOUS TINAMU 

Rhynchotus rufescens 

Above cinereous ; head, wings, and back crossed by black bars with 
pale ochraceous edgings ; neck reddish ; primaries chestnut ; beneath 
pale cinereous, strongly tinged with rufous on the neck and breast ; 
chin white ; bill ashy, beneath at base yellowish ; feet dark flesh- 
colour ; length 14, wing 9.5 inches. Female similar, but larger. 

This large Tinamu, known to the Argentines as 
the Perdiz grander or Great Partridge, is found on 
the pampas wherever long grasses abound, and 
extends as far south as the Colorado river, its place 
being taken in Patagonia by Calodromas elegans. It 
is never met with in woods or thickets, and requires 
no shelter but the giant grasses, through which it 
pushes like a RaiL Wherever the country becomes 
settled and the coarse indigenous grasses are replaced 
by those of Europe, it quickly disappears, so that it 
is already extinct over a great portion of the Buenos- 
Ayrean pampas* 

This species is solitary in its habits, conceals itself 
very closely in the grass, and flies with the greatest 
reluctance, I doubt if there is anywhere a bird with 
such a sounding flight as the Tinamu ; the whirr 
of its wings can only be compared to the rattling of 
a vehicle driven at great speed over a stony road. 
From the moment it rises until it alights again there 
is no cessation in the rapid vibration of the wings ; 
but, like a ball thrown by hand, the bird flies straight 



222 BIRDS OF LA PLATA 

away with extraordinai^ violence until the impel- 
ling force is spent^ when it slopes gradually towards 
the earthy the distance it is able to accomplish at a 
flight being from 800 to 1500 yards. This flight it 
can repeat when driven up again as many as three 
times, after which the bird can rise no more. 

The call of the Great Partridge is heard, in fine 
weather, at all seasons of the year, especially near 
sunset, and is uttered while the bird sits concealed 
in the grass, many individuals answering each other ; 
for although I call it a solitary bird, many birds are 
usually found living near each other. The song or 
call is composed of five or six notes of various length, 
with a mellow flute-like sound, and so expressive 
that it is, perhaps, the sweetest bird-music heard on 
the pampas. 

The eggs are usually five in number, nearly round, 
highly polished, and of a dark reddish-purple or 
wine colour ; but this beautiful tint in a short time 
changes to a dull leaden hue. The nest is a mere 
scrape, insufficiently lined with a few grass-leaves. 
The young birds appear to leave the mother (or 
father, for it is probable that the male hatches the 
eggs) at a very early period. When still very small 
they are found living, like the adults, a solitary life, 
with their faculties, including those of flight and 
the musical voice, in a high state of perfection. 



SPOTTED TINAMU 223 

SPOTTED TINAMU 

* Nothura maculosa 

Above pale yellowish brown, barred with black and brown and 
streaked with fulvous white ; wing-feathers ashy black, crossed on 
both webs by fulvous bands ; beneath rich yellowish brown ; throat 
white ; breast and flanks spotted and banded with brownish black ; 
bill and feet yellowish brown; length ii, wing 5.5 inches. Female 
similar, but larger. 

The Perdiz comun or Common Partridge of the 
pampas, as it is always called — the naturalist's name 
of Tinamu being utterly unknown in the southern 
part of South America — is much smaller than the 
Perdiz grandef but in its form, slender curved beak, 
bare legs, and in the yellowish mottled plumage, 
generally resembles it. It also inhabits the same 
kind of open grassy country, and is abundant every- 
where on the pampas and as far south as the valley 
of the Rio Negro in Patagonia. It is solitary ; but a 
number of individuals are usually found in proxi- 
mity ; and in lonely places on the pampas, where 
they are excessively abundant, I have seen three 
or four meet together and play in the manner of 
kittens, darting out from a place of concealment 
at each other, the pursued bird always escaping by 
turning off at right angles or by suddenly crouching 
down and allowing the pursuer to spring over it. 

It is very tame in disposition, and flies so reluc- 
tantly that it is not necessary to shoot them where 
they are very abundant, as any number can be 
killed with a long whip or stick. It moves on the 



324 BIRDS OF LA PLATA 

ground in a leisurely qpnner, uttering as it walks 
or runs a succession of low whistling notes. It has 
two distinct songs or calls, pleasing to the ear and 
heard all the year round ; but with greater frequency 
in spring, and where the birds are scarce and much 
persecuted, in spring only. One is a succession of 
twenty or thirty short impressive whistling notes of 
great compass, followed by half a dozen rapidly 
uttered notes, beginning loud and sinking lower till 
they cease ; the other call is a soft continuous trill, 
which appears to swell mysteriously on the air, for 
the listener cannot tell whence it proceeds ; it lasts 
several seconds, and then seems to die away in the 
distance. 

It is an exceedingly rare thing to see this bird 
rise except when compelled. I believe the power of 
flight is used chiefly, if not exclusively, as a means 
of escape from danger. The bird rises up when 
almost trodden upon, rushing through the air with 
a surprising noise and violence. It continues to rise 
at a decreasing angle for fifty or sixty yards, then 
gradually nears the earth, till, when it has got to 
a distance of two or three hundred yards, the violent 
action of the wing ceases and the bird glides along 
close to the earth for some distance, and either 
drops down or renews its flight. I suppose many 
birds fly in much the same way ; only this Tinamu 
starts forward with such amazing energy that until 
this is expended and the moment of gliding comes, 
the flight is just as ungovernable to the bird as 
the motion of a brakeless engine, rushing along 



SPOTTED TINAMU 325 

at full speed, would be to the driver. The bird knows 
the danger to which this peculiar character of its 
flight exposes it so well that it is careful to fly only 
to that side where it sees a clear course. It is some- 
times, however, compelled to take wing suddenly, 
without considering the obstacles in its path; it 
also often miscalculates the height of an obstacle, 
so that for Tinamus to meet with accidents when 
flying is very common. In the course of a short ride 
of two miles, during which several birds sprang up 
before me, I have seen three of these Tinamus dash 
themselves to death against a fence close to the path, 
the height of which they had evidently misjudged. I 
have also seen a bird fly blindly against the wall of 
a house, killing itself instantly. A brother of mine 
told me of a very curious thing he once witnessed. 
He was galloping over the pampas, with a very 
violent wind blowing in his face, when a Tinamu 
started up before his horse. The bird flew up into 
the air vertically, and, beating its wings violently, 
and with a swiftness far exceeding that of its ordinary 
flight, continued to ascend until it reached a vast 
height, then came down again, whirling round and 
round, striking the earth a very few yards from the 
spot where it rose, and crushing itself to a pulp with 
the tremendous force of the fall. It is very easy to 
guess the cause of such an accident : while the 
Tinamu struggled blindly to go forward, the violent 
wind, catching the under surface of the wings, forced 
it upwards, until the poor bird, becoming hopelessly 
confused, fell back to earth. I have often seen a 

D II 



226 BIRDS OF LA PLATA 

Swallow, Gull, or HawJi^ soaring about in a high 
wind, suddenly turn the under surface of its wings 
to the wind and instantly shoot straight up, apparently 
without an effort, to a vast height, then recover itself, 
and start off in a fresh direction. The Tinamu, 
when once launched on the atmosphere, is at the 
mercy of chance ; nevertheless had this incident 
been related to me by a stranger I should not have 
recorded it* 

This Tinamu is frequently run down and caught 
by well-mounted gaucho boys ; the bird frequently 
escapes into a kennel in the earth, but when it sees 
no refuge before it and is hotly pursued, it sometimes 
drops dead. When caught in the hand they ** feign 
death,'* or swoon, but on being released quickly 
recover their faculties. 

The nest is a slight hollow scratched in the ground 
under a thistle or in the grass, and lined with a few 
dry leaves. The number of eggs laid varies from five 
to eight. These are elliptical, with polished shells, 
and as a rule are of a wine-purple colour ; but the 
hue varies somewhat, some eggs having a reddish 
tinge and others a deep liver-colour. 

In Patagonia the Spotted Tinamu is replaced by the 
very closely allied Darwin's Tinamu, Nothura darwinu 

This species, called Perdiz chicOf or Little Partridge, 
by the natives, is somewhat smaller and paler in 
colouring than the common Tinamu of the pampas, 
but very closely resembles the young of that species. 
It inhabits Patagonia, and is nowhere very numerous, 
but appears to be thinly and equally distributed on 



MARTINETA 227 

the dry, sterile plains of that region, preferring places 
abounding in thin scrub. In disposition it is extremely 
shy, and when approached springs up at a distance 
ahead and runs away with the greatest speed and 
apparently much terrified. Sometimes when thus 
running it utters short whistled notes like the allied 
species. It rises more readily and with less noise 
than the pampas bird, and has a much higher flight. 
It has one call-note, heard only in the love-season — 
a succession of short whistling notes, Hke those of 
the iV. maculosa^ but without the rapidly uttered con- 
clusion. 

The nest is made under a small scrubby bush, and 
contains from five to seven eggs, in form and colour 
like those of N* maculosa, except that the^reddish- 
purple tint is paler. 



MARTINETA 

Calodromas elegans 

Above densely banded and spotted with black and pale fulvous ; 
head cinereous^ with black striations ; a long recurved vertical crest 
of black feathers^ partly edged with cinereous ; two lateral stripes of 
the head above and beneath the eye and throat cinnamon white ; 
beneath pale cinnamon, breast with numerous black cross-bars and 
black shaft-spots ; belly, flanks, and under tail-coverts with broad 
black cross bands; wings ashy black, with numerous cross bands 
of pale cinnamon; bill blackish, feet bluish-grey; length 14.5, wing 
8.3 inches. Female similar. 

This fine game-bird in its si2;e and mottled plumage 
resembles the Rhynchotus rufescens of the pampas, 
which it represents in the Patagonian region south 



228 BIRDS OF LA PLATA 

of the Rio Colorado, It differs externally in the 
more earthy hue of its plumage, which is protective 
and harmonises admirably with the colour of its 
sterile surroundings ; also in having a shorter beak, 
and in being adorned with a long, slender, black crest, 
which the bird when excited carries directed for- 
wards like a horn. There is, however, an anatomical 
difference which seems to show that the two species 
are not very near relations. The structure of the 
intestinal canal in the Martineta is most peculiar, 
and unlike that of any other bird I have ever dis- 
sected : the canal divides near the stomach into a 
pair of great ducts which widen towards the middle 
and extend almost the entire length of the abdominal 
cavity, and are set with rows of large membranous 
claw-shaped protuberances. 

The Martineta inhabits the elevated table-lands, 
and is found chiefly where patches of scattered dwarf 
scrub occur among the thorny thickets. Apparently 
they do not require water, as they are met with in 
the driest situations where water never collects. 
They are extremely fond of dusting themselves, and 
form circular nest-like hollows in the ground for 
that purpose ; these hollows are deep and neatly 
made, and are visited every day by the same birds 
throughout the year. They live in coveys of from 
half a dozen to twenty or thirty birds, and when 
disturbed do not as a rule take to flight at once, but 
jump up one after another and run away with amazing 
swiftness, uttering as they run shrill, squealing cries, 
as if in the greatest terror. Their flight, although

Martineta Tin am u 

Culodromas elegans (il'Orb. ul Gcoira.) 



MARTINETA 229 

violent, is not so sounding as that of the Rufous 
Tinamu, and differs remarkably in another respect. 
Every twenty or thirty yards the wings cease beating 
and remain motionless for a second, when the bird 
renews the effort ; thus the flight is a series of rushes 
rather than a continuous rush like that of the other 
species. It is also accompanied with a soft wailing 
note, which appears to die away and swell again as 
the flapping of the wings is renewed. 

The call-note of the Martineta is never heard in 
winter ; but in the month of September they begin 
to utter in the evening a long, plaintive, slightly 
modulated whistle, the birds sitting concealed and 
answering each other from bush to bush. As the 
season advances the coveys break up, and their call 
is then heard on every side, and often all day long, 
from dawn until after dark. The call varies greatly 
in different birds, from a single whistle to a per- 
formance of five or six notes, resembling that of 
the great Partridge, but inferior in compass and 
sweetness. They begin to breed in October, making 
the nest at the roots of a small isolated bush. The 
eggs vary in number from twelve to sixteen ; they 
are elliptical in form, of a beautiful deep green in 
colour, and have highly polished shells. 

It is probable, I think, that this species possesses 
some curious procreant habits, and that more than 
one female lays in each nest ; but owing to the 
excessive wariness of the bird in^a state of nature it 
is next to impossible to find out anything about it. 
No doubt the day will come when naturalists will 



230 BIRDS OF LA PLATA 

find the advantage of ddBiesticating the birds the 
life histories of which they wish to learn : may it 
come before all the most interesting species on the 
globe are extinct I 



COMMON RHEA 

Fhea americana 

Above, head blackish ; neck wWtfsh, becoming black at the base 
of the neck and between the shoulders; rest slatey grey; beneath, 
throat and upper neck whitish, becoming black at the base of the neck, 
whence arise two black lateral crescents, one on either side of the 
upper breast ; rest of under surface whitish ; front of tarsus through- 
out covered with broad transverse scutes ; length about 52 inches. 

The Common Rhea (called Nandu in the Guarani 
language, ChueH by the pampas Indians, and Ostrich 
by Europeans) is found throughout the Argentine 
Republic down to the Rio Negro in Patagonia, and, 
in decreasing numbers, to a considerable distance 
south of that river. Until within very recent times 
it was very abundant on the pampas, and I can 
remember the time when it was common within 
forty miles of Buenos Ayres city. But it is now 
becoming rare, and those who wish to have a hand 
in its extermination must go to a distance of three 
or four hundred miles from the Argentine capital 
before they can get a sight of it. 

The Rhea is peculiarly well adapted, in its size, 
colour, faculties, and habits, to the conditions of 
the level woodless country it inhabits ; its lofty 
stature, which exceeded that of any of its enemies 



COMMON RHEA 231 

before the appearance of the European mounted 
hunter^ enables it to see far ; its dim grey plumage, 
the colour of the haze, made it almost invisible to 
the eye at a distance, the long neck being so slender 
and the bulky body so nearly on a level with the tall 
grasses ; while its speed exceeded that of all other 
animals inhabiting the same country. When watching 
the chase of Ostriches in the desert pampas, abound- 
ing in giant grasses, it struck me forcibly that this 
manner of hunting the bird on horseback had brought 
to light a weakness in the Rhea — a point in which 
the correspondence between the animal and its en- 
vironment is not perfect. The Rhea runs smoothly 
on the surface, and where the tall grass-tussocks are 
bound together, as is often the case, with slender 
twining plants, its legs occasionally get entangled, 
and the bird falls prostrate, and before it can struggle 
up again the hunter is close at hand and able to 
throw the bolas — the thong and balls, which, striking 
the bird with great force, wind about its neck, wings, 
and legs, and prevent its escape. When I questioned 
Ostrich hunters as to this point they said that it was 
true that the Rhea often falls when running hotly 
pursued through long grass, and that the deer 
(Cervus campestris) never falls because it leaps over 
the large tussocks and all such obstructions. This 
small infirmity of the Rhea would not, however, 
have told very much against it if some moderation 
had been observed in hunting it, or if the Argentine 
Government had thought fit to protect it ; but in 
La Plata, as in North America and South Africa, the 



232 BIRDS OF LA PLATA 

licence to kill, which evef^one possesses, has been 
exercised with such ^eal and fury that in a very few 
more years the noblest Avian type of the great bird- 
continent will be as unknown on the earth as the 
Moa and the ^pyornis. 

The Rhea lives in bands of from three or four to 
twenty or thirty individuals. Where they are not 
persecuted they show no fear of man, and come about 
the houses, and are as familiar and tame as domestic 
animals* Sometimes they become too familiar. At 
one estancia I remember an old cock bird that con- 
stantly came alone to feed near the gate, which had 
so great an animosity against the human figure in 
petticoats that the women of the house could not go 
out on foot or horseback without a man to defend 
them from its attacks. When the young are taken 
from the parent bird they become, as Ai^ara truly 
says, ** domestic from the first day," and will follow 
their owner about like a dog. It is this natural lame- 
ness, together with the majesty and quaint grace of 
its antique form, which makes the destruction of 
the Rhea so painful to think of. 

When persecuted, Rheas soon acquire a wary 
habit, and escape by running almost before the 
enemy has caught a sight of them ; or else crouch 
down to conceal themselves in the long grass ; and 
it then becomes difficult to find them, as they lie 
close, and will not rise until almost trodden on. Their 
speed and endurance are so great that, with a fair 
start, it is almost impossible for the hunter to over- 
take them, however well mounted. When the bird 



COMMON RHEA 233 

is running, the wings hang down as if injured, 
but usually one wing is raised and held up like a 
great sail, for what reason it is impossible to say* 
When hard pressed, the Rhea doubles frequently 
and rapidly at right angles to its course ; and if the 
pursuer^s horse is not well trained to follow the bird 
in all its sudden turns without losing ground he is 
quickly left far behind. 

In the month of July the love-season begins, and 
it is then that the curious ventriloquial bellowing, 
booming, and wind-like sounds are emitted by the 
male. The young males in the flock are attacked 
and driven off by the old cock-bird ; and when 
there are two old males they fight for the hens. Their 
battles are conducted in a rather curious manner, 
the combatants twisting their long necks together 
like a couple of serpents, and then viciously biting 
at each other^s heads with their beaks ; meanwhile 
they turn round and round in a circle, pounding 
the earth with their feet, so that where the soil is 
wet or soft they make a circular trench where they 
tread* The females of a flock all lay together in a 
natural depression in the ground, with nothing to 
shelter it from sight, each hen laying a dozen or more 
eggs* It is common to find thirty to sixty eggs in a 
nest, but sometimes a larger number, and I have 
heard of a nest being found containing one hundred 
and twenty eggs* If the females are many the cock 
usually becomes broody before they finish laying, 
and he then drives them with great fury away and 
begins to incubatet The hens then drop their eggs 



234 BIRDS OF LA PLATA 

about on the plains ; aii^ from the large number 
of wasted eggs found it seems probable that more 
are dropped out of than in the nest. The egg when 
fresh is of a fine golden yellow^ but this colour 
grows paler from day to day, and finally fades to a 
parchment-white. 

After hatching the young are assiduously tended 
and watched over by the cock, and it is then dan- 
gerous to approach the Rhea on horseback, as the 
bird with neck stretched out horizontally and out- 
spread wings charges suddenly, making so huge and 
grotesque a figure that the tamest horse becomes 
ungovernable with terror. 

Eagles and the large Cairion Hawk are the enemies 
the Rhea most fears when the young are still small, 
and at the sight of one flying overhead he crouches 
down and utters a loud snorting cry, whereupon 
the scattered young birds run in the greatest terror 
to shelter themselves under his wings. 

Darwin*s Rhea, Rhea darwinif differs little in 
colouring from the Common Rhea, which it replaces 
south of the Rio Negro. From this river it ranges 
south to the Straits of Magellan. The Indians call 
it ** Mold Chueki ** — short or dwarf Chueke ; its 
Spanish name is ** Avestruz petizo'* They were 
formerly very abundant along the Rio Negro ; 
unhappily some years ago their feathers commanded 
a very high price ; Gauchos and Indians found that 
hunting the Ostrich was their most lucrative em- 
ployment ; consequently these noble birds were 
slaughtered in such numbers that they have been 



COMMON RHEA 335 

almost exterminated wherever the nature of the 
country admits of their being chased* When on the 
Rio Negro I was so anxious to obtain specimens of 
this Rhea that I engaged several Indians by the offer 
of a liberal reward to hunt for me^ but they failed 
to capture a single adult bird* I can only set down 
here the most interesting facts I was able to collect 
concerning its habits, which are very imperfectly 
known. 

When pursued it frequently attempts to elude the 
sight by suddenly squatting down amongst the 
bushes, which have a grey foliage to which the colour 
of its plumage closely assimilates. When hard pressed 
it possesses the same habit as the Common Rhea of 
raising the wings alternately and holding them up 
vertically : and also doubles suddenly like that 
species. Its speed is greater than that of the Common 
Rhea, but it is sooner exhausted. In running it 
carries its head stretched forward almost horizon- 
tally, which makes it seem lower in stature than the 
allied species — hence the vernacular name of ** Short 
Ostrich.*' It is found in flocks of from three or four 
to thirty or more individuals. It begins to lay at the 
end of July, that is, a month before the Rhea ameri- 
cana. Several females lay in one nest, which is merely 
a slight depression lined with a little dry rubbish ; 
as many as fifty eggs are sometimes found in one 
nest. A great many wasted or huacho eggs, as they 
are called, are also found at a distance from the nest. 
I examined a number of eggs brought in by the 
hunters, and found them vary greatly in shape, size. 



236 BIRDS OF LA PLATA 

and colour. The averagesize of the eggs was the 
same as those of the Common Rhea ; in shape they 
were more or less elliptical, scarcely any two being 
precisely alike. The shell has a fine polish, and 
when newly laid the colour is deep, rich green. They 
soon fade, however, and the side exposed to the sun 
first assumes a dull mottled green ; then this colour 
fades to yellowish, and again to pale stone-blue, 
becoming at last almost white. The comparative 
age of each egg in the nest may be known by the 
colour of the shell. The male incubates and rears 
the young ; and the procreant habits seem altogether 
like those of Rhea americana* 

The young are hatched with the legs feathered 
to the toes ; these leg-feathers are not shed, but are 
gradually worn off, as the bird grows old, by con- 
tinual friction against the stiff, scrubby vegetation. In 
adults usually a few scattered feathers remain, often 
worn down to mere stumps ; but the hunters told 
me that old birds are sometimes taken with the legs 
entirely feathered, and that these birds frequent 
plains where there is very little scrub. The plumage 
of the young is dusky grey, without white and black 
feathers. When a year old they acquire by moulting 
the mottled plumage of the adults, but do not attain 
their full size until the third year.
