Male.--Very similar to the male of C. jugularis, but distinguished by
a patch or broad band of orpiment-orange next to the black chest. A
male from Cuyo measures: Wing, 55; tail, 37; culmen from base, 21;
bill from nostril, 17; tarsus, 16.
Female.--Similar to the female of C. jugularis. A female from Siquijor
measures: Wing, 50; tail, 34; culmen from base, 19; bill from nostril,
15; tarsus, 15.
The young male gradually acquires the black chin and throat in the
manner of C. jugularis and develops the orange patch at the same time.
"Ten males average: Length, 120; wing, 55; tail, 39; culmen, 22;
tarsus, 15; middle toe with claw, 15. Three females, length, 109;
wing, 51; tail, 36; culmen, 22; tarsus, 14; middle toe with claw,
14. Iris dark brown; bill, legs, feet, and nails black. Breeding in
December in Palawan and in February in Culion. Called by natives of
Palawan 'chee-wit'." (Bourns and Worcester MS.)
