The Bermuda hawk (Bermuteo avivorus) is an extinct bird of prey that was endemic to Bermuda. It was the sole member of the genus Bermuteo.
The Bermuda hawk inhabited the island of Bermuda where it is recorded in the fossil record. It is thought to account for a report of sightings of raptors made on the island in 1603 by Diego Ramírez, which mentions their possible island tameness: "very handsome sparrow-hawks, so stupid that we even clubbed them".
The species apparently was not present in 1623, when Captain John Smith noted that there were only migrant raptors on Bermuda. [3] [ failed verification ] Its date of extinction is not known but is presumed to have followed the human settlement on the island in the 17th century and may have been due to hunting and the introduction of invasive species, such as feral pigs.

The Accipitridae is one of the four 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 256 species which are divided into 12 subfamilies and 75 genera.
The northern harrier, also known as the marsh hawk or ring-tailed hawk, is a bird of prey. It breeds throughout the northern parts of the northern hemisphere in Canada and the northernmost USA.
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.
Accipiter is a genus of birds of prey in the family Accipitridae. Most species are called sparrowhawks, but there are many sparrowhawks in other genera too, such as Tachyspiza.
The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species.
The besra, also called the besra sparrowhawk, is a bird of prey in the family Accipitridae. It was formerly placed in the genus Accipiter. The name "besra" is from the Hindi word for the species.
The great black hawk is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures.
The roadside hawk is a relatively small bird of prey found in the Americas. This vocal species is often the most common raptor in its range. It has many subspecies and is now usually placed in the monotypic genus Rupornis instead of Buteo.
The Chinese sparrowhawk (Tachyspiza soloensis) is a bird of prey in the family Accipitridae. This species was formerly placed in the genus Accipiter.
The Flores hawk-eagle is a large raptor in the family Accipitridae. It is an endemic species to the Lesser Sunda Islands in Indonesia. A member of the genus Nisaetus, it was considered as a subspecies of and conspecific with the changeable hawk-eagle but genetic studies have evidenced it as a legitimate species. A forest dwelling predator, this species is classified as Critically Endangered due to habitat loss and persecution.
The Sulawesi hawk-eagle, also known as Celebes hawk-eagle, is a medium-sized, approximately 64 cm (25 in) long, crestless brown raptor in the family Accipitridae. The adults have rufous-brown, boldly marked head and chest feathers, dark brown wings and black-barred white below. The young has white head and underparts.
The semicollared hawk is a rare bird of prey species in the family Accipitridae. It is found in Colombia, Ecuador, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests. It is potentially being affected by habitat loss.
The Gundlach's hawk is a species of bird of prey in the family Accipitridae. It was formerly placed in the genus Accipiter. It is one of 21 endemic bird species of Cuba. The common name and Latin binomial commemorate the German-Cuban ornithologist Juan Cristobal Gundlach (1810–1896). It is threatened by habitat loss and human persecution.
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.
Nisaetus, the crested hawk-eagles, is a genus of raptor in the subfamily Aquilinae, found mainly in tropical Asia. They were earlier placed within the genus Spizaetus but molecular studies show that the Old World representatives of that genus are closer to the genus Ictinaetus than to the New World Spizaetus. They are slender-bodied, medium-sized hawk-eagles with rounded wings, long feathered legs, barred wings, crests and usually adapted to forest habitats.
The variable hawk is a polymorphic species of bird of prey in the family Accipitridae.
