Description
This species' plumage is virtually identical to that of the American crow. Individuals may be distinguished by in-hand criteria such as smaller wing chord and tail length, shorter tarsus, and smaller bill. Like the American crow, the sexes look the same. Older birds in breeding condition may be reliably sexed by in-hand criteria such as cloacal protuberance (male) or by brood patch (female). Younger birds may not attain breeding condition as they assist at the nest.
