Cebu (Everett, Bourns & Worcester, McGregor).
Male.--A large triangular mantle-patch scarlet-vermilion, the black
bases of the feathers showing somewhat; lower back ochraceous tinged
with green; remainder of upper parts, including sides of head and neck,
wings, and tail, glossy blue-black; under parts cinereous; chin, a
narrow line on middle of breast, center of abdomen, crissum, thighs,
axillars, wing-lining, and inner webs of quills white; flanks washed
with light olive. Length, 90; wing, 53; tail, 25; culmen from base,
10; bill from nostril, 6; greatest width of bill, 7; tarsus, 14.
"Adult female.--Above brown, head faintly washed with olive; back,
wing-coverts, and outer webs of secondaries heavily washed with
olive-yellow, rump almost entirely of the latter color; entire under
surface grayish white faintly tinged with olive-yellow, lighter
along center of breast and abdomen; under wing-coverts, axillars,
and inner webs of quills pure white.
"Young male.--Like female but lacks yellow wash on outer webs of
secondaries, the wing and tail being black as in adult male." (Bourns
and Worcester.)
"The locality Panaon, assigned to this species in the Catalogue of
Birds, is a manifest error. The type specimen, an unsexed bird which
was rightly supposed to be a male, was obtained in Cebu by Everett. No
additional specimen seems to have been secured until 1892, when we
again found it in Cebu. Ten males average as follows: Length, 90;
wing, 52; tail, 26; culmen, 11.4; tarsus, 13.4; middle toe with claw,
13.7. Six females, length, 89; wing, 52; tail, 25; culmen, 11.6;
tarsus, 13.4; middle toe with claw, 14. Iris chocolate-brown; bill,
legs, feet, and nails black. Breeding in June. Food fruit." (Bourns
and Worcester MS.)
