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. Taxonomy Bucco viridis was the scientific name proposed by Pieter Boddaert in 1783 for a green barbet that had been described by Georges-Louis Leclerc, Comte de Buffon in 1780 based on a specimen collected in India. It was illustrated by François-Nicolas Martinet in a hand-coloured plate. It was placed in the genus Megalaima proposed by George Robert Gray in 1842 who suggested to use this name instead of Bucco. Its type locality is Mahé, Puducherry in southwestern India. It is a monotypic species. In 2004, molecular phylogenetic research of barbets revealed that the Megalaima species form a clade, which also includes the fire-tufted barbet, the only species placed in the genus Psilopogon at the time. Asian barbets were therefore reclassified under the genus Psilopogon. Results of a phylogenetic study of Asian barbets published in 2013 indicate that the white-cheeked barbet is most closely related to the yellow-fronted barbet (P. flavifrons), which is endemic to Sri Lanka. The relationship of the white-cheeked barbet with some close relatives in its taxon is illustrated below. Description The white-cheeked barbet is 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 is not easily differentiated from that of the brown-headed barbet. During hot afternoons, they may
