The blue-eared barbet (Psilopogon duvaucelii) is an Asian barbet. Barbets are a group of near passerine birds with a worldwide tropical distribution. They get their name from the bristles which fringe their heavy bills.

Description

This small barbet is 17–18 cm (6.7–7.1 in) in length. It is a plump bird, with a short neck, large head and short tail. The bill is dark, and the body plumage is green, but the subspecies have different head patterns. The adult male of the form, M. d. cyanotis, which occurs from northeast India ‍and Bangladesh to peninsular Thailand has a black forehead, blue midcrown, ear coverts and throat, red markings above and below the earcoverts, and orange cheeks. The female has a duller head pattern with a more orange tint to the patches above and below the ear coverts, and the juvenile has a green head with some blue on the ear coverts and throat.

The male’s territorial call is a repeated loud ko-tek. Other calls include a whistled pleow.
