Corvus tristis (Grey Crow)

Wikipedia Abstract

The grey crow (Corvus tristis), formerly known as the bare-faced crow, is about the same size (42–45 cm in length) as the Eurasian carrion crow (Corvus corone) but has somewhat different proportions and quite atypical feather pigmentation during the juvenile phase for a member of this genus. The juvenile bird by comparison has remarkably pale plumage being light brown to cream, the wings, tail and primaries showing blackish-brown and fawn and the head and underparts often almost white.
