THREE NEW BIRDS FROM THE
PHILIPPINE ISLANDS

Austin L, Rand

Chief Curator, Department of Zoology
AND

D. S, Rabor
Associate, Department of Biology, Silliman University

These new subspecies are named from the extensive material
collected by the junior author in Bohol (1955), Mount Malindang,
Zamboanga (1956), and Samar (1957). The descriptions are being
published in advance of the main reports on the three collections.
These reports are in the editor's hands. We are indebted to Dr. S. D.
Ripley of Yale University for the loan of comparative material.
The junior author is also indebted to the Guggenheim Foundation
for a grant which enabled him to study in the United States in
1957-58.

Trichoglossus johnstoniae pistra, new subspecies

Type. — Chicago Natural History Museum no. 227110, from
Masawan, 3500-4500 feet altitude. Mount Malindang, Zamboanga
Peninsula, Mindanao. Adult male, collected May 10, 1956, by
D. S. Rabor.

Diagnosis. — Like T. j. johnstoniae of southeastern Mindanao but
differs in that the red of forehead, face and chin is deeper, duller
rosy red; the nuchal band is blue black instead of purple black; the
green of the upper parts is slightly darker; and the yellow of the
under parts is slightly more vivid.

Measurements.— T. j. pistra: cT (7) 105-111 (av. 107.9), 9 (6)
106-110 (av. 108 mm.).

T.j. johnstoniae, Mount Apo: d' 104, 106, 106, 9 105, 108 mm.

Range. — Mount Malindang, from 3500 to 5500 feet altitude.

NATURAL
HISTORY SURVEY

276 FIELDIANA: ZOOLOGY, VOLUME 39

Remarks. — Hitherto the species was known only from eastern
and central Mindanao. Pistra is the native Subano name for this
species.

Harpactes ardens linae, new subspecies

Type. — Chicago Natural History Museum no. 223128, from
Sandayong, Sierra Bullones, Bohol. Adult male, collected April 5,
1955, by D. S. Rabor.

Diagnosis. — Like ardens from Mindanao but male with more
black on head, the black extending farther backward to the middle
of crown (less reddish purple in crown); upper parts darker and
duller orange brown. Also like luzoniensis of Luzon but differs in
the longer and wider (more robust) bill.

In the females the differences in coloration between ardens and
linae are not as pronounced as in the males.

Measurements. — H. a. linae, Bohol: wing, cf (6) 139-147 (av.
143.5), 9 (5) 138-148 (av. 142.2); culmen from base, cf (6) 22.5-
26.5 (av. 24.3), 9 (5) 22.5-27.5 (av. 24.3). Samar: culmen from
base, cf (3) 24.5, 25.5, 26, 9 (5) 23.5-26 (av. 24.7 mm.).

H. a. luzoniensis, Luzon: culmen from base, cf (3) 21.5, 22, 24,
9 23.

H. a. ardens, Mindanao: culmen from base, <f (13) 24.5-26.5
(av. 25.4), 9 (16) 23-26 (av. 24.8 mm.).

Range. — Bohol and Samar. Leyte birds presumably belong here.

Remarks. — This new race combines the characters of the more
southern ardens (large bill) and of the more northern luzoniensis
(duller orange brown back, blacker head). It is named after the
wife of the junior author, Lina Florendo, who very ably aided in
the field work on Bohol.

Coracina striata boholensis, new subspecies

Type. — Chicago Natural History Museum no. 223311, from
Sandayong, Sierra Bullones, Bohol. Adult female, collected April 3,
1955, by D. S. Rabor.

Diagnosis. — Most like C. s. kochii of Mindanao but differs in
that the gray of the under parts is darker; the black barring of
the abdomen is heavier; the under tail coverts have sparse, but
narrow and distinct bars (not pure white or flecked with black) ; and
the black and white barring of the rump is less distinct. In the

RAND AND RABOR: BIRDS FROM THE PHILIPPINES 277

female these characters are more clear cut than in the male. Size
slightly larger.

Also like panayensis of Negros but differs in that in the male
the gray of the head is paler; the black of the face is much reduced,
restricted to a dark area about the eye (not black extending to
forehead and as a wash on the throat) ; the abdomen and especially
the under tail coverts have the white bars wider and the black bars
reduced; the black and white barring of the rump is reduced in
distinctness and in extent. The female differs in that the upper
parts are paler gray; the throat and breast are barred black and
white (not with a heavy mixture of gray); the black bars on the
under parts are narrower, the white ones wider, especially posteriorly;
and the barring of the rump is less distinct and of lesser extent.
Size slightly smaller.

Measurements. — C. s. A:oc^m, Mindanao : wing, cf (6) 150-159, 9
(6) 149-154.

C. s. boholensis, Bohol and Samar: wing, cf (8) 162-166 (av. 164),
9 (10) 149-162 (av. 154.6).

C. s. panayensis, Negros: wing, cT" (5) 165-172, 9 (7) 163-172.

Range. — Bohol and Samar.

Remarks. — The barring of the breast of Bohol females is slightly
more distinct and the crown is paler than in Samar birds, but the
difference is not of subspecific status. This new race is intermediate
between the quite different panayensis and kochii but closer to the
latter.

Of the 10 males and 10 females of boholensis and the 6 males and
7 females of kochii examined, only one specimen, a male from Mount
Malindang (the only specimen from western Mindanao), is not
separable on the characters listed. It is tentatively assigned with
the rest of the Mindanao birds.
