Pale-faced Bulbul
Pycnonotus leucops
Endemic to Borneo’s montane highlands, this brownish-olive bulbul, with its white face and large, dark eyes, is distinctive. Forages in fruiting trees, as well as low, scrubby growth lining the rocky peaks of the highest mountains. Listen for low, churred calls, given repeatedly or strung into slightly up-and-down song. Formerly treated as a subspecies of Flavescent Bulbul, which has a darker face and does not occur on Borneo.
Identification
At 17.5–19 cm long the pale-faced bulbul is smaller than the flavescent bulbul, with which it was once lumped, which reach 21.5–22 cm in length. Its colouring is mainly brown or grey-brown, darker above than below, with a white or whitish face and throat, and bright yellow undertail-coverts.

Reliably distinguished from other green-plumaged oropendolas by pale green-and-red bill. Found in rainforest canopy and edges as well as along rivers, in villages, and in savanna woodlands. Groups move noisily through the forest canopy in search of fruit and flowers. Large flocks are sometimes seen commuting between roosting and feeding areas. Distinctive song of male can be heard at a great distance.
