Cochoa Hodgs., J. A. S. B., v, p. 359 (1836). Type, Cochoa viridis.
The genus Cochoa contains, in India, two species of Thrush which are in many ways somewhat aberrant, especially in their type of coloration, which rather reminds one of the birds of the genus Pteruthius, and in the short, very broad bill. The nostrils are large and oval, the rictal bristles obsolete and the tarsi powerful but short. The wing is long and pointed with a minute first primary and the tail is of moderate length very slightly graduated.
The young are boldly squamated above and barred below, as in many other of the genera in this family. The nidification and the eggs are typically Thrush-like.
