Leucopternis
''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. Species Traditionally, ''Leucopternis'' contains significantly more species than given here. However, as the genus probably was polyphyletic, moves of species to other genera were proposed and have been accepted by the American Ornithologists' Union's South American Check-list Committee and North American Check-list Committee,Chesser et al. (2012) except that the South American Committee placed the former ''L. lacernulatus'' in the existing genus ''Buteogallus'' instead of in a new genus ''Amadonastur'' by itself. The other species were placed in the genera ''Cryptoleucopteryx'', ''Morphnarchus'', ''Pseudastur'', and ''Buteogallus ''Buteogallus'' is a genus of birds of prey in the family Accipitridae.

Black-faced Hawk
The black-faced hawk (''Leucopternis melanops'') 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 Description The black-faced hawk is a medium-sized hawk with black and white plumage. It has a white underbelly, a large white head streaked with some black and a characteristic black “mask”. Below the black mask, it has a dark orange cere and a black tipped bill. The back of the hawk is dark all the way down to the tail with some mottling. However, a single white band sticks out near the base of the tail. Juvenile plumage resembles adult plumage except that j ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Morphnarchus
The barred hawk (''Morphnarchus princeps'') is a species of bird of prey in the family Accipitridae. It has also been known as the black-chested hawk. It is found in Colombia, Costa Rica, Ecuador, Panama, and Peru. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest. 10,000 to 100,000 barred hawks are thought to exist throughout Central and South America. Barred hawks mainly live in the dense forests of the lowland and mountainous areas. Taxonomy and evolution Philip Sclater first classified the barred hawk in 1865. Barred hawks are in the family Accipitridae that contains all the hawks, eagles, and old world vultures.Raposo do Amaral, Fabio S., Matthew J. Miller, Luis F.

Buteogallus
''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). Taxonomy and species The genus ''Buteogallus'' was introduced in 1830 by the French naturalist René Lesson to ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pseudastur
''Pseudastur'' is a genus of bird of prey in the family Accipitridae. It contains the following species: Systematics The name ''Pseudastur'' was coined by Edward Blyth, but was first published in George Robert Gray George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger broth ...'s Index. The type species is the white hawk, ''Falco albicollis'' Latham, 1790. The species were placed for some time in the genus '' Leucopternis'', however this genus was found to be polyphyletic. In 2012 the American Ornithologists' Union split Leucopternis, placing the white hawk and its relatives under the old name ''Pseudaster''.

Accipitridae
The Accipitridae is one of the three families within the order Accipitriformes, and is a family of small to large birds 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 (except Antarctica) and a number of oceanic island groups. Some species are migratory. The family contains 255 species which are divided into 70 genera. Many well-known birds such as hawks, eagles, kites, harriers and Old World vultures are included in this group. The osprey is usually placed in a separate family (Pandionidae), as is the secretary bird ( Sagittariidae), and the New World vultures are also usually now regarded as a separate family or order. Karyotype data indicate the accipitrids analysed are indeed a distinct monophyletic group. Systematics and phylog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
