Cinereous Bulbul Hemixos cinereus Scientific name definitions

A rather large, arboreal pycnonotid, the Cinereous Bulbul is endemic to the Sunda region of South-East Asia, occurring on the Thai-Malay Peninsula, Sumatra, and Borneo, where it is conspicuous and quite common in montane forest, second growth, wooded parks, and gardens. It is unlike any other bulbul in plumage, being mostly gray with a white throat, belly and undertail-coverts, and a contrasting black mask. This species often gathers at fruiting trees, usually in groups of fewer than 20 individuals, and it also occasionally joins mixed-species flocks in the canopy, with the birds noisily emitting their ringing tree-tree-tree calls. Two subspecies are recognized, which are sometimes treated as separate species on account of their distinct plumage: birds on Borneo have vivid yellow-green wings and tail, but elsewhere in the species’ range both of these tracts are brown.
