Family: Accipitridae

Binomial name
Buteogallus anthracinus
(Deppe, 1830)
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. On the contrary, the Mangrove Black Hawk, traditionally considered a distinct species, is now generally considered a subspecies, subtilis, of the Common Black Hawk.[1]
The Common Black Hawk is a breeding bird in the warmer parts of the Americas, from the Southwestern United States 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 fifteen to one hundred feet above the ground in a tree, often a mangrove. Nests are often reused and tend to grow bigger. It lays one to three eggs (usually one), which are whitish with brown markings. |

Buenos días Luis,
Siempre hay que estar pendiente de tus fotos; esta realmente es para gradecer en cuanto a calidad y documentación. Muy buen trabajo, excelente captura de esta ave en un entorno que resulta bastante natural. Ni sabía que existen falconiformes con dietas basadas en cangrejos, me resulta muy curioso.
Saludos, que sigas bien.
