The white-cheeked barbet or small green barbet (Psilopogon viridis) is a species of Asian barbet found in southern India. It is very similar to the more widespread brown-headed barbet (or large green barbet, Psilopogon zeylanicus), but this species has a distinctive supercilium and a broad white cheek stripe below the eye and is found in the forest areas of the Western Ghats, parts of the Eastern Ghats and adjoining hills. The brown-headed barbet has an orange eye-ring but the calls are very similar and the two species occur together in some of the drier forests to the east of the Western Ghats. Like all other Asian barbets, they are mainly frugivorous (although they may sometimes eat insects), and use their bills to excavate nest cavities in trees.
The white-cheeked barbet is 16.5–18.5 cm in length. It has a brownish head streaked with white, sometimes giving it a capped appearance. The bill is pale pink. Size varies from the larger northern birds to the southern ones.
Like many other Asian barbets, white-cheeked barbets are green, sit still, and perch upright, making them difficult to spot. During the breeding season which begins at the start of summer their calls become loud and constant especially in the mornings. The call, a monotonous Kot-roo...Kotroo... starting with an explosive trrr is not easily differentiated from that of the brown-headed barbet. During hot afternoons, they may also utter a single note wut not unlike the call of collared scops owl or coppersmith barbet. Other harsh calls are produced during aggressive encounters.[
