Gray-chinned Sunbird

Unobtrusive small bird of brushy woodland and forest understory in tropical lowlands, mainly in drier habitats. Usually seen as singles or pairs, low in weedy growth. Male blue-black overall; with good views, note the blue forehead, ‘jowls,’ and rump. Female in West Mexico gray-brown overall, in East Mexico rich brown overall. Similar female Varied Bunting has a smaller bill and different call note: a wet plik; Blue Bunting call is a high tsik in West Mexico, a metallic chink in East Mexico.

Breeding birds show yellow cap, black triangle under eye, streaked back and reddish-brown sides. Looks remarkably different in fall with distinctive lime green above and gray below with bold white eyering. Breeds mainly in secondary forests, especially areas with large shrubs and young trees. Does well in disturbed habitats, particularly power line cuts and areas that have been logged. Forages for insects. Winters in Central America.

Nest parasite that lays its eggs in the nests of Red-billed and Brown firefinches. Breeding males are glossy black, while females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The color of the bill is red in southeast Africa and whitish in western, northern, and central Africa. Found in savanna, scrub, farmland, and towns. Mimics the vocalizations of its host firefinches: low rattling series and high-pitched whistled notes. In southeast Africa, can be separated from other indigobirds by its red bill. Very similar to other indigobirds elsewhere on the continent. Breeding males can be separated by their all-black wings that lack a pale brownish panel. The mimicked vocalizations of its host species can also help confirm identification. In non-breeding plumage, similar to non-breeding Pin-tailed Whydah but separated by red legs.
