Male.—Above olive-green, brightest on the rump; chin, throat, and 
chest glossy blue-black washed with dark aster-purple; remainder of 
under parts gamboge-yellow, darkest next to the black chest-patch ; wing- 
feathers dark brown, outer webs edged with olive-green, inner webs edged 
with white; rectrices black, two or three outer pairs tipped with white. 
Bill, legs, and nails black. A male from Bohol measures: Wing, 55; 
tail, 38; culmen from base, 19; bill from nostril, 15; tarsus, 15. 
Female.—Above similar to the male; below gamboge- or lemon-yellow, 
whitish on the chin, and with obscure dusky mottlings on the throat, 
brightest yellow on middle of breast and abdomen. A female from 
Siquijor measures: Wing, 50; tail, 33; culmen from base, 19; bill from 
nostril, 15; tarsus, 15. 
The young male resembles the female and from this plumage gradually 
acquires the black throat and chest. In many specimens (very old 
males?) there is more or less orange next to the black chest, while the 
forehead and a small area above the eye often develop a few metallic blue 
feathers. 
“This sunbird shows great variability in the color of the breast, some 
specimens having an amount of orange approximating, but never quite 
equaling, that displayed by C. aurora. Ten males average: Length, 
119; wing, 56; tail, 40; culmen, 21; tarsus, 14; middle toe with claw, 
14. Ten females, length, 114; wing, 52; tail, 36; culmen, 20; middle 
toe with claw, 14; tarsus, 14. Bill, legs, feet, and nails black; iris very 
dark brown. Breeds in February and March.” (Bourns and Wor- 
cester MS.) 
Three eggs of the yellow-breasted sunbird from Marinduque, May 
17, 1888, collected by Steere, are described as follows: “Shape ovate. 
Ground-color whitish partially obscured by the mottled gray under mark- 
ings, which cover the greater part of the shell; over markings pale brown, 
with a few spots and irregular marks of a deep brown. Measurements 
16 mm. by 12 mm. 
“The nest is a neatly woven pocket-shaped structure, with a roofed 
entrance at the side. It is composed of fiber, dead grasses, and other 
forest débris bound together with spiders’ webs and lined with cotton 
and fine grass.” (Grant and Whitehead.)
