common black hawk
The common black hawk (''Buteogallus anthracinus'') is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. It formerly included the Cuban black hawk (''Buteogallus gundlachii'') as a subspecies. The mangrove black hawk, traditionally considered a distinct species, is now generally considered a subspecies, ''B. a. subtilis'', of the common black hawk.〔
==Description==
The adult common black hawk is long and weighs on average. It has very broad wings, and is mainly black or dark gray. The short tail is black with a single broad white band and a white tip. The bill is black and the legs and cere are yellow. The adults resemble zone-tailed hawks, but have fewer white bars on their tail and are larger in size.
Sexes are similar, but immature birds are dark brown above with spotting and streaks. Their underparts are buff to whitish with dark blotches, and the tail has a number of black and white bars.
