Buteogallus is a genus of birds of prey in the family Accipitridae. All members of this genus are essentially neotropical, but the distribution of a single species extends slightly into the extreme southwestern United States. Many of the species are fond of large crustaceans and even patrol long stretches of shore or riverbank on foot where such prey abounds, but some have a rather different lifestyle. Unlike many other genera of raptor, some members are referred to as "hawks", and others as "eagles".
Most of the species have a characteristic tail pattern. This consists of a black base, a wide white middle band, a wide black band, and a quite narrow white band on the feathertips that is often hard to discern or may be lost when the feathers are very worn. Only the white-necked hawk and the rufous crab hawk have a very different tail patterns (see also below).
The genus Buteogallus was introduced in 1830 by the French naturalist René Lesson to accommodate the rufous crab hawk, which is therefore the type species. [2] [3] The name is a portmanteau of the genus name Buteo introduced in 1779 by Bernard Germain de Lacépède for the buzzards and the genus Gallus introduced in 1760 by Mathurin Jacques Brisson for the junglefowl. [4] The genus now contains nine species. [5]

The solitary eagles (formerly Harpyhaliaetus ) are a more inland relative of the "black-hawk" group of Buteogallus – in phenotype they are essentially hefty common black-hawks with lighter body plumage and in one species a small crest. Insofar as there are differences in anatomy, these seem to be related to the different prey they hunt (namely reptiles). Together with the savanna hawk, they seem to be close to some species that were uncomfortably placed in Leucopternis . As that genus was apparently polyphyletic, the present article follows a proposal to unite the solitary eagles as well as the slate-colored hawk ("Leucopternis" schistaceus) with Buteogallus, to agree with the morphological and mtDNA sequence data., [6] [7] with the addition of the white-necked hawk, "Leucopternis" lacernulatus. [8]
For a long time various systematists have proposed moving the slate-colored hawk to Buteogallus. Together with the crab hawks and solitary eagles form a sequence of plumage patterns that nicely agrees with the DNA-based phylogeny: the slate-colored hawk looks very much like a smaller, shorter-legged and lighter common black hawk. The case of the white-necked hawk is more puzzling. It is visually and ecologically almost identical to the sympatric mantled hawk (Leucopternis polionotus) and some allopatric white hawks (L. albicollis) but differs in tail color. According to the mtDNA data, it is very closely related to the savanna hawk, which is visually dissimilar, appearing like a very light Buteogallus which has an ochre-grey coloration due to abundant pheomelanins. Either there has been strong convergent evolution in plumage and ecology – perhaps a case of mimicry – between the white-necked and the mantled hawks, or the mtDNA data is misleading due to ancient hybrid introgression. In the respect, the white-necked hawk specimen sampled showed indications of heteroplasmy. [6]
The placement of the peculiarly apomorphic rufous crab hawk in regard to all these birds must be considered unresolved for the time being. [6]
The fossil record of Buteogallus has meanwhile turned out to be quite rich indeed, with many species being erroneously assigned to other genera at first. The genus – like many buteonines of today – probably succeeded earlier birds of prey during the Miocene and never seems to have occurred outside the Americas. From the time of the last ice age, an array of prehistoric species is known, some of them very large. On Cuba, a particularly gigantic species survived deep into the last ice age, but probably not until human settlement.
Eagle is the common name for the golden eagle, bald eagle, and other birds of prey in the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. True eagles comprise the genus Aquila. Most of the 68 species of eagles are from Eurasia and Africa. Outside this area, just 14 species can be found—two in North America, nine in Central and South America, and three in Australia.
Hawks are birds of prey of the family Accipitridae. They are very widely distributed and are found on all continents except Antarctica.
The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents and a number of oceanic island groups. Some species are migratory. The family contains 255 species which are divided into 70 genera.
Buteo is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in the New World. As both terms are ambiguous, buteo is sometimes used instead, for example, by the Peregrine Fund.
Buzzard is the common name of several species of birds of prey.
The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species.
Aquila is the genus of true eagles. The genus name is Latin for "eagle", possibly derived from aquilus, "dark in colour". It is often united with the sea eagles, buteos, and other more heavyset Accipitridae, but more recently they appear to be less distinct from the slenderer accipitrine hawks than previously believed. Eagles are not a natural group but denote essentially any bird of prey large enough to hunt sizeable vertebrate prey.
The black-chested buzzard-eagle is a bird of prey of the hawk and eagle family (Accipitridae). It lives in open regions of South America. This species is also known as the black buzzard-eagle, the gray buzzard-eagle, or analogously with "eagle" or "eagle-buzzard" replacing "buzzard-eagle", or as the Chilean blue eagle. It is sometimes placed in the genus Buteo.
The solitary eagle or montane solitary eagle is a large Neotropical eagle. It is also known as the black solitary eagle.
The rufous crab hawk or rufous crab-hawk, is a Near Threatened species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found on Trinidad and along the South American coastline from eastern Venezuela to southern Brazil.
Leucopternis is a Neotropical genus of birds of prey in the family Accipitridae. They are associated with tropical forest, and are uncommon or rare. Their plumage is largely black or gray above and white below, and they have distinctive orange ceres.
The white-necked hawk is a Vulnerable species of bird of prey in the subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is endemic to Brazil.
The black-faced hawk is a species of bird of prey in the family Accipitridae. This low-density species has traditionally been believed to be restricted to Amazon Basin north of the Amazon River, but there are several records south of this river, in, for example, the Brazilian states of Pará and Acre, and southeastern Peru. It is closely related to the white-browed hawk and individuals showing a level of intermediacy between the two species are known, suggesting that they rarely hybridize
The grey-backed hawk is an Endangered species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found in Ecuador and far northern Peru.
The barred hawk is a species of bird of prey in the family Accipitridae. It has also been known as the black-chested hawk.
The black-and-white hawk-eagle is a bird of prey species in the eagle and hawk family (Accipitridae). It is found throughout a large part of tropical America, from southern Mexico to northern Argentina.
The Cuban black hawk is a bird of prey in the family Accipitridae. It is endemic to Cuba and several outlying cays.
Buteogallus borrasi is a species of giant buteonine hawk which went extinct in the early Holocene. Formerly endemic to Cuba, this huge bird of prey probably fed on Pleistocene megafauna. Little is known about its appearance and ecology, so no common name has been given.
Woodward's eagle is an extinct species of black hawk that lived in North America and the Caribbean during the Late Pleistocene. Remains have been found in the La Brea Tar Pits in the United States and in Cuba. Despite the common name, the species is technically a gigantic variety of hawk as it is a member of the still extant black hawk genus, Buteogallus, within the Buteoninae subfamily that are chiefly referred to as hawks, and not the Aquilinae subfamily most eagles belong to.
The common black hawk is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and vultures.
