Buff-vented Bulbul Iole crypta

Dull brown bulbul with a long slender bill and pale gray eyes. Gray-eyed Bulbul is very similar but has darker, buffier underparts and is more warmly-colored overall; ironically, Gray-eyed Bulbul’s buffy rump is brighter. Olive Bulbuls are dark-eyed and darker overall, with little to no contrast between upper- and underparts. Inhabits forest and forest edge from lowlands up into the foothills. Gives sharp, high “whit” and “cher-wit” calls.
