Sumatra Koçoası Cochoa beccarii

Bulky and sluggish inhabitant of Sumatra’s highland forests. Resembles a cross between a large thrush and a small crow; both sexes are glossy black with an electric-blue tail, wing panel, and crown. Males have a dark face, whereas females have a buffy one. Dull naked red skin around the eye can be evident at close range. Like other cochoas, its inactive habits can make this species difficult to see as it perches up in dense vegetation. Song is a haunting mournful whistle.
