Everything about The Common Black Hawk totally explained
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.
The Common Black Hawk is a breeding
bird in the tropical
New World, from the
southwestern U.S. through
Central America to
Venezuela,
Peru,
Trinidad and the
Lesser Antilles.
This is a mainly coastal, resident bird of
mangrove swamps, estuaries and adjacent dry open woodland, though there are inland populations, including a migratory population in northwestern
Mexico and
Arizona.
The adult Common Black Hawk is 43–53 cm long and weighs 930g 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.
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.
The Common Black Hawk feeds mainly on
crabs, but will also take small
vertebrates and eggs. This species is often seen soaring, with occasional lazy flaps, and has a talon-touching aerial courtship display. The call of the Common Black Hawk is a distinctive piping
spink-speenk-speenk-spink-spink-spink.
It builds a platform nest of sticks at middle or upper heights in a tree, often a mangrove. It lays one to three eggs (usually one), which are whitish with brown markings.
The shorter-winged
Mangrove Black Hawk is considered to be subspecies of Common Black Hawk by some authors. The
Cuban Black-Hawk was also recently split from
B. anthracinus (AOU 2007).
Protection status
The Common Black Hawk is protected in the far north of its range (in the USA) under the
Migratory Bird Treaty Act of 1918.
