Gray-sided Laughingthrush

Slim, pale greenbul. The yellow streaks on the underparts are always hard to see. The crown color varies geographically: can be olive-green or gray. Found in moist forest, especially montane forest. The most distinctive attribute of this species is its behavior: creeping along midstory branches in almost woodpecker-like fashion, frequently flicking out one wing. Gives nasal calls and a descending series of more musical whistles. Easily confused with other greenbul species, but much paler overall than most greenbuls, and wing-flicking behavior is diagnostic.

Odd and unique member of the waxbill family. Males are yellow and olive-green with a black head; females are olive-green. Both sexes have a pink bill. Males vary geographically in how yellow or olive-green their back is, how much orange they show below, and whether or not they have a yellow collar. Found in and around montane forest, usually in pairs or small groups. Quiet and inconspicuous bird. The call is a sharp “tsik.” Males have a similar pattern to some weavers but are separated by their pink bill. Also similar to orioles, but much smaller.

Small and compact with a small bill and a shorter tail compared to larger sparrows. Males have a gray head, a vivid rusty shoulder patch, a black throat, and a yellow patch at the base of the white mustache. Females are relatively clean-looking compared to males. Song is a series of high-pitched, sharp “tzip-tzip-tzip…” notes. The flight call is higher-pitched than larger sparrows. Breeds in thick scrub and trees where it builds a large and prominent nest that has unique thermoregulating properties for hot climates. A partial and short-distance migrant; moves in tight, fast-moving flocks.
