Eagle is the common name for many large birds of prey of the family Accipitridae. Eagles belong to several groups of genera, some of which are closely related. Most of the 60 species of eagle are from Eurasia and Africa. Outside this area, just 14 species can be found—2 in North America, 9 in Central and South America, and 3 in Australia.
The harpy eagle is a neotropical species of eagle. It is also called the American harpy eagle to distinguish it from the Papuan eagle, which is sometimes known as the New Guinea harpy eagle or Papuan harpy eagle. It is the largest and most powerful raptor found throughout its range, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has caused it to vanish from many parts of its former range, and it is nearly extirpated from much of Central America. In Brazil, the harpy eagle is also known as royal-hawk. The genus Harpia, together with Harpyopsis and Morphnus, form the subfamily Harpiinae.
The ferruginous hawk, Buteo regalis, is a large bird of prey and belongs to the broad-winged buteo hawks. An old colloquial name is ferrugineous rough-leg, due to its similarity to the closely related rough-legged hawk.
The African hawk-eagle is a large bird of prey. Like all eagles, it belongs to the family Accipitridae. This species’ feathered legs mark it as a member of the Aquilinae subfamily. The African hawk-eagle breeds in tropical Sub-Saharan Africa. It is a bird of assorted woodland, including both savanna and hilly areas but the tend to occur in woodland that is typically dry. The species tends to be rare in areas where their preferred habitat type is absent. This species builds a stick nest of around 1 m (3.3 ft) across in a large tree. The clutch is generally one or two eggs. The African hawk-eagle is powerfully built and hunts small to medium sized mammals and birds predominantly, occasionally taking reptiles and other prey as well. The call is a shrill kluu-kluu-kluu. The African hawk-eagle is considered a fairly stable species and a species of Least Concern per the IUCN.
The African harrier-hawk, harrier hawk or gymnogene is a bird of prey. It is about 60–66 centimetres (24–26 in) in length. It breeds in most of Africa south of the Sahara. The only other member of the genus is the allopatric Madagascar harrier-hawk.
The changeable hawk-eagle or crested hawk-eagle(Nisaetus cirrhatus) is a large bird of prey species of the family Accipitridae. More informal or antiquated English common names include the marsh hawk-eagle or Indian crested hawk-eagle. It is a member of the subfamily Aquilinae, with signature feathers, absent in tropical raptors from outside this subfamily, covering the tarsus. It was formerly placed in the genus Spizaetus, but studies pointed to the group being paraphyletic resulting in the Old World members being placed in Nisaetus and separated from the New World species. It is a typical “hawk-eagle” in that it is an agile forest-dwelling predator and like many such eagles readily varies its prey selection between birds, mammals or reptiles as well as other vertebrates. Among the members of its genus, the changeable hawk-eagle stands out as the most widely distributed, adaptable and abundant species. Birds show a wide range of variation in plumage from pale to dark, varying with moult and age giving rise to the name "changeable".
The grey-headed fish eagle is a fish-eating bird of prey from South East Asia. It is a large stocky raptor with adults having dark brown upper body, grey head and lighter underbelly and white legs. Juveniles are paler with darker streaking. It is often confused with the lesser fish eagle and the Pallas's fish eagle. The lesser fish eagle is similar in plumage but smaller and the Pallas's fish eagle shares the same habitat and feeding behaviour but is larger with longer wings and darker underparts. Is often called tank eagle in Sri Lanka due to its fondness for irrigation tanks.
The ornate hawk-eagle is a fairly large bird of prey from the tropical Americas. Formerly, some authorities referred to this species as the crested hawk-eagle, a name that may cause some confusion as it is more commonly used for an Asian eagle species. Like all eagles, it is in the family Accipitridae. This species has a feathered tarsus that marks it as a member of the Aquilinae or booted eagle subfamily. This species is notable for the vivid colors and bold markings of adults, which differ considerably from the far more whitish plumage of the juvenile bird. The ornate hawk-eagle ranges from central Mexico south through much of Central America and in a somewhat spotty but broad overall range into South America, including in the west apart from the Andes and broadly on the Atlantic side especially Brazil down to as far as Southeast Brazil and northern Argentina. This species is found largely in primary forests with tall trees, although can be found in many forest types. The ornate hawk-eagle female lays almost always a single egg and the species has a fairly prolonged breeding cycle like many tropical raptors, especially due to a lengthy post-fledging stage on which juveniles are dependent on their parents. It is a diversified and exceptionally powerful predator which takes a range of prey, usually various medium-to-large-sized birds and small-to-medium-sized mammals as well as occasional reptiles. Like many forest-dependent raptors, especially those in the tropical and subtropical regions, this species is likely under the pressing threat of deforestation. The decline of forest habitat in this species range, especially the Amazon rainforest, led the IUCN to uplist the ornate hawk-eagle as Near Threatened in 2016.
The long-tailed hawk is an African bird of prey in the family Accipitridae. It is the only member of the genus Urotriorchis.
The Madagascar fish eagle or Madagascar sea-eagle, is a large bird of prey in the family Accipitridae which also includes many other diurnal raptors such as kites, buzzards and harriers. It is endemic to the coastal strip in the northwest of Madagascar. It is about 63 cm (25 in) long and has a pale brown head, dark brown body and white tail. The Madagascan fish eagle has been suffering from a declining population and is threatened by habitat destruction and persecution, and the International Union for Conservation of Nature has rated its conservation status as being "critically endangered".
The Chaco eagle or crowned solitary eagle, is an endangered bird of prey from eastern and central South America. Typically it is known simply as the crowned eagle which leads to potential confusion with the African Stephanoaetus coronatus. Due to its rarity, not much is known about its biology or population.
Doria's goshawk or Doria's hawk, is a raptor, the only member of the genus Megatriorchis.
The Réunion harrier or Réunion marsh harrier is a bird of prey belonging to the marsh harrier group of harriers. It is now found only on the Indian Ocean island of Réunion, although fossil material from Mauritius has been referred to this species. It is known locally as the papangue or pied jaune. The Malagasy harrier of Madagascar and the Comoro Islands was previously treated as a subspecies of this bird but is increasingly regarded as a separate species. The Réunion harrier appears to be declining in numbers and it is classed as an endangered species.
Gundlach's hawk is a species of bird of prey in the family Accipitridae. It is one of 21 endemic bird species of Cuba. The common name and Latin binomial commemorate the German-Cuban ornithologist Juan Cristobal Christoff Gundlach (1810–1896). It is threatened by habitat loss and human persecution.
Henst's goshawk is a species a bird of prey in the family Accipitridae. It is a large, diurnal bird endemic to the island of Madagascar. It is an obligate forest species that occurs at very low densities on the island and is rarely seen. It can only occupy the primary and secondary forests found within the island. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and plantations.
The Congo serpent eagle is a species of bird of prey in the family Accipitridae. It is the only member of the monotypic genus Dryotriorchis, although it was formerly placed in Circaetus. This species is distributed across the African tropical rainforest, including upper and lower Guinean forests. This serpent eagle specializes in hunting in these forests’ dark understories. It has two subspecies, the nominate subspecies Dryotriorchis spectabilis spectabilis and Dryotriorchis spectabilis batesi. Though monotypic, it appears to be very closely related to Circaetus. This hawk is a medium-sized bird with distinctive short, rounded wings and a long, rounded tail. It is varying shades of brown on its back and has a slight crest. Its breast is white with variable amounts of a rufous wash and, in the nominate subspecies, is covered in round, blackish spots. The subspecies D. s. batesi only has these dots on its flanks. The Congo serpent eagle closely resembles Cassin's hawk-eagle, and some ornithologists believe that this likeness is a rare example of avian mimicry. It is a very vocal raptor, and often is one of the most heard species in its habitat.
The mantled hawk is a South American species of bird of prey in the family Accipitridae.
The Andaman Serpent Eagle,, also known as the Andaman dark-serpent eagle or the dark serpent eagle, is a medium-sized bird in the family Accipitridae, the raptor family, that is only found in India on the Andaman Islands. It is currently classified as vulnerable and is experiencing population declines. This species, unlike Spilornis cheela, is incredibly understudied and so many things about its behaviour and ecology are still widely unknown.
Cassin's hawk-eagle or Cassin's eagle, is a relatively small eagle in the family Accipitridae. Its feathered legs mark it as member of the Aquilinae or booted eagle subfamily. A forest-dependent species, it occurs in primary rainforests across western, central and (marginally) eastern Africa where it preys on birds and tree squirrels. It was named after John Cassin who first described it in 1865. Due to widespread habitat destruction, its populations are steadily declining but have not yet warranted upgrading its status from Least Concern.
The Peregrine Fund is a non-profit organization founded in 1970 that conserves threatened and endangered birds of prey worldwide. The successful recovery of the peregrine falcon in the United States, which was removed from the U.S. Endangered Species List in 1999, enabled the organization to expand its mission to include other endangered raptors around the world. The Peregrine Fund is headquartered at its World Center for Birds of Prey in Boise, Idaho, on a 580-acre (2.3 km2) campus with breeding and research facilities, an administrative office, interpretive center, research library, and archives.
