Chestnut-capped Warbler

Medium-sized sunbird of foothill forest and forest edge on Java; uncommon to rare in upper montane and lowland habitats. Forages actively in pairs, mixed flocks, or singly. Both sexes are very similar to Crimson Sunbird, but note Javan's bright white belly and sides. Female Javans can also be confused with White-flanked and the Leptocoma sunbirds, but have more white on the sides and belly than those species. Song is a very flat and insect-like series of dry “chit” notes; also gives a sparrow-like “chiweet.”

A dark boubou, almost wholly matte black except for its grayish eyes, found in the shadows of thickets and dense vegetation. Common at higher elevations in Cameroon, Equatorial Guinea, and Nigeria. Noisy and usually found by its distinctive calls. Song is a series of whistles often ending in a harsh note: “go-WHEE-chk!”. Also makes a grating chatter, meowing “reawr” calls, and a quick, upslurred “kew-ick!” whistle, as well as other calls.

A very small, sandy-colored finch-like weaver with a scaly crown, a pale pink bill, and a black moustache on a white throat that gives it a fierce-looking expression. Small groups are resident and nomadic in grassy arid savanna, where there are trees and scrub nearby in which to build their untidy oval grass nests. The species sometimes gives a soft, reedy “cheet-cheet-cheet” flight call. The Sociable Weaver is much larger than the Scaly Weaver, with a blue-gray bill.
