Aquilinae
The Aquilinae are a subfamily of eagles of the family Accipitridae. The general common name used for members of this subfamily is "booted eagle", although this is also the common name of a member of the subfamily.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C. J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Michael Wink & Gjershaug, J. O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. ''Zootaxa'' 4216 (4), 301-320. At one point, this subfamily was considered inclusive with the Buteoninae (commonly known as buzzards or buteonine hawks) based probably on some shared morphological characteristics.Amadon, D. (1982). ''The genera of booted eagles: Aquila and relatives''. Journal of the Yamashina Institute for Ornithology, 14(2-3), 108-121. However, research on the DNA of the booted eagles has shown that they are a monophyletic group that probably have had mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 phylogeny ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African Hawk Eagle (Aquila Spilogaster)
The African hawk-eagle (''Aquila spilogaster'') 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.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. Zootaxa, 4216(4), 301-320. 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 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 si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martial Eagle
The martial eagle (''Polemaetus bellicosus'') is a large eagle native to sub-Saharan Africa.Ferguson-Lees & Christie, ''Raptors of the World''. Houghton Mifflin Company (2001), . It is the only member of the genus ''Polemaetus''. A species of the booted eagle subfamily (Aquilinae), it has feathering over its tarsus. One of the largest and most powerful species of booted eagle, it is a fairly opportunistic predator that varies its prey selection between mammals, birds and reptiles. It is one of few eagle species known to hunt primarily from a high soar, by stooping on its quarry.Steyn, P. (1983). ''Birds of prey of southern Africa: Their identification and life histories''. Croom Helm, Beckenham (UK). 1983. An inhabitant of wooded belts of otherwise open savanna, this species has shown a precipitous decline in the last few centuries due to a variety of factors. The martial eagle is one of the most persecuted bird species in the world. Due to its habit of taking livestock and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wedge-tailed Eagle
The wedge-tailed eagle (''Aquila audax'') is the largest bird of prey in the continent of Australia. It is also found in southern New Guinea to the north and is distributed as far south as the state of Tasmania. Adults of this species have long, broad wings, fully feathered legs, an unmistakable wedge-shaped tail, an elongated maxilla, a strong beak and powerful feet. The wedge-tailed eagle is one of 12 species of large, predominantly dark-coloured booted eagles in the genus '' Aquila'' found worldwide. Genetic research has clearly indicated that the wedge-tailed eagle is fairly closely-related to other, generally large members of the ''Aquila'' genus.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O.

Ornate Hawk-eagle
The ornate hawk-eagle (''Spizaetus ornatus'') 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.Friedmann H. (1935). ''A new race of the Crested Hawk-eagle Spizaetus ornatus''. Journal of the Washington Academy of Sciences, 25 (10): 450-451. 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.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O. (2017). ''Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)''. Zootaxa, 4216(4), 301-320.

Booted Eagle
The booted eagle (''Hieraaetus pennatus'', also classified as ''Aquila pennata'') is a medium-sized mostly migratory bird of prey with a wide distribution in the Palearctic and southern Asia, wintering in the tropics of Africa and Asia, with a small, disjunct breeding population in south-western Africa. Like all eagles, it belongs to the family ''Accipitridae''. Taxonomy The booted eagle was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the eagle, falcons and relatives in the genus '' Falco'' and coined the binomial name ''Falco pennatus''. Gmelin based his description on "Le Faucon Patu" or "Falco pedibus pennatis" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. Brisson had examined a specimen in the collection of Madame de Bandeville who was also known as Marie Anne Catherine Bigot de Graveron (1709-1787 ...

Crowned Eagle
The crowned eagle, also known as the African crowned eagle or the crowned hawk-eagle (''Stephanoaetus coronatus''), is a large bird of prey found in sub-Saharan Africa; in Southern Africa it is restricted to eastern areas.Sinclair & Ryan (2003). ''Birds of Africa south of the Sahara''. Its preferred habitats are principally riparian woodlands and various forests. The crowned eagle is the only extant member of the genus ''Stephanoaetus''. A second species, the Malagasy crowned eagle (''Stephanoaetus mahery'') became extinct after humans settled on Madagascar.Goodman, Steven M. (1994). Proceedings of the Biological Society of Washington 107(3): 421–428 ISSN 0006-324''Description of a new species of subfossil eagle from Madagascar: ''Stephanoaetus'' (Aves: Falconiformes) From The Deposits Of Ampasambazimba''.

Eagle
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 68 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. Eagles are not a natural group but denote essentially any kind of bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrates. Description Eagles are large, powerfully-built birds of prey, with heavy heads and beaks. Even the smallest eagles, such as the booted eagle (''Aquila pennata''), which is comparable in size to a common buzzard (''Buteo buteo'') or red-tailed hawk (''B. jamaicensis''), have relatively longer and more evenly broad wings, and more direct, faster flight – despite the reduced size of aerodynamic feathers. Most eagles are larger than any other raptors apart from some vultures. The smalles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buteoninae
The Buteoninae are a subfamily of birds of prey which consists of medium to large, broad-winged species. They have large, powerful, hooked beaks for tearing flesh from their prey, strong legs, and powerful talons. They also have extremely keen eyesight to enable them to spot potential prey from a distance. This subfamily contains the buzzards (buteonine hawks) with great diversity in appearance and form and some appearing eagle-like, with at least 50 species included overall in the subfamily. At one time, several types were grouped, including large assemblages such as booted eagles, but modern studies using mitochondrial DNA clarified that this subfamily was smaller than formerly classified. Systematics The subfamily Buteoninae includes about 55 currently recognized species. Unlike many lineages of 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 morpho ...

Nisaetus
''Nisaetus'' (Crested hawk-eagles group) is a genus of subfamily Aquilinae found mainly in tropical Asia. They were earlier placed within the genus ''Spizaetus'' but molecular studies show that the Old World representatives were closer to the genus '' Ictinaetus'' than to the New World ''Spizaetus'' (in the stricter sense). They are slender-bodied, medium-sized hawk-eagles with rounded wings, long feathered legs, barred wings, crests and usually adapted to forest habitats. Taxonomy and species These Old World species were formerly placed in the genus ''Spizaetus''. They were moved to the resurrected genus ''Nisaetus'' based on the results of molecular genetic studies published in 2005 and 2007. The genus ''Nisaetus'' had been introduced in 1836 by the English naturalist Brian Houghton Hodgson with the mountain hawk-eagle as the type species. The genus name ''Nisaetus'' combines the Medieval Latin ''nisus'' for a sparrowhawk with the Ancient Greek Ancient Greek include ...

Aquila (genus)
''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 buteos, sea eagles, and other more heavyset Accipitridae, but more recently they appear to be less distinct from the more slender accipitrine hawks than previously believed. Eagles are not a natural group, but denote essentially any bird of prey large enough to hunt sizeable (about 50 cm long or more overall) vertebrate prey. Taxonomy and systematics The genus ''Aquila'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the golden eagle (''Aquila chrysaetos'') as the type species. ''Aquila'' belongs to a close-knit group of "typical" eagles including genera Hieraaetus, ''Lophaetus'', '' Ictinaetus'' ''and Clanga.'' This group occurs as a clade within the larger group of "booted" eagles (tribe Aquilini or subfamily Aquilinae).Boyd, JohAccipitriformes, ''Taxonomy in Flux Checklist''. The plum ...
