Buteonine
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, which seemed to have radiated out of Africa or South Asia, the Buteoninae clearly originated in the Americas based on fossil records and current species distributions ( ...

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] |
Red-tailed Hawk
The red-tailed hawk (''Buteo jamaicensis'') is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of '' Buteo'' in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the " chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts.Preston, C. R. (2000). ''Red-tailed Hawk''. Stackpole Books. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands (from small meadows to the treed fringes of more extensive prairies), coniferous and deciduous forests, agricult ...

Eagle Looking Left
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 sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Prey
Birds of prey or predatory birds, also known as raptors, are hypercarnivorous bird species that actively hunt and feed on other vertebrates (mainly mammals, reptiles and other smaller birds). In addition to speed and strength, these predators have keen eyesight for detecting prey from a distance or during flight, strong feet with sharp talons for grasping or killing prey, and powerful, curved beaks for tearing off flesh. Although predatory birds primarily hunt live prey, many species (such as fish eagles, vultures and condors) also scavenge and eat carrion. Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, ornithologists typically use the narrower definition followed in this page, excluding both piscivorous predators such as storks, herons, gulls, skuas, penguins and kingfishers, as well as primarily insectivorous birds such as passerine birds (e.g. shrikes) and birds like nightjars and ...

White-tailed Eagle
The white-tailed eagle (''Haliaeetus albicilla'') is a very large species of sea eagle widely distributed across temperate Eurasia. Like all eagles, it is a member of the family Accipitridae (or accipitrids) which includes other diurnal raptors such as hawks, kites, and harriers. One of up to eleven members in the genus '' Haliaeetus'', which are commonly called sea eagles, it is also referred to as the white-tailed sea-eagle.Helander, B., & Stjernberg, T. (2003). ''Action plan for the conservation of white-tailed sea eagle (''Haliaeetus albicilla'')''. In Convention on the Conservation of European Wildlife and Natural Habitats, Strasbourg, France. Sometimes, it is known as the ern or erne (depending on spelling by sources),Love, J. A. (1983). ''The return of the Sea Eagle''. Cambridge University Press, . gray sea eagle and Eurasian sea eagle.

Grey-headed Fish Eagle
The grey-headed fish eagle (''Haliaeetus ichthyaetus'') is a fish-eating bird of prey from South East Asia.Robson, C. (2000). ''A Field Guide to the Birds of South-East Asia''. UK: New Holland Publishers. It is a large stocky raptor with adults having dark brown upper body, grey head and lighter underbelly and white legs.Rasmussen, P. C. & Anderton, J. C. (2005). ''Birds of South Asia''. The Ripley Guide. Vols 1 and 2. Washington D.C. and Barcelona: Smithsonian Institution and Lynx Edicions. Juveniles are paler with darker streaking. It is often confused with the lesser fish eagle (''Haliaeetus humilis'') 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.Ferguson-Lees, J. & Christie, D. A. (2001). ''Raptors of the World''. London, UK: Christ ...

Lesser Fish Eagle
The lesser fish eagle (''Haliaeetus humilis'') is a species of ''Haliaeetus'' found in the Indian subcontinent, primarily in the foothills of the Himalayas, and south-east Asia. There are records from Gujarat, Central India and in more recent times from the Kaveri river valley in southern India, although the south Indian records are now thought to come from an isolated population, disjunct from the species' normal range. Some taxonomic authorities place this species in the monotypic genus Ichthyophaga. Others place it in the genus Haliaeetus. Lesser fish eagles are fish-eating birds that have feet adapted to aid in gripping slippery fish. They have strongly curved talons, and spicules along the underside of the birds' toes help to grip fish as they pull them from the water. There are two subspecies: ''Haliaeetus humilis humilis'', which is native to the Malaysian Peninsula, Sumatra, Borneo, and Sulawesi; and ''Haliaeetus humilis plumbeus'', which is native to Kashmir through ...

Steller's Sea Eagle
Steller's sea eagle (''Haliaeetus pelagicus''), also known as Pacific sea eagle or white-shouldered eagle, is a very large diurnal bird of prey in the family Accipitridae. It was described first by Peter Simon Pallas in 1811. No subspecies are recognised. A sturdy eagle, it has dark brown plumage with white wings and tail, a yellow beak, and yellow talons. Typically, it is the heaviest eagle in the world, at about , but in some standard measurements, may be ranked below the harpy eagle (''Harpia harpyja'') and the Philippine eagle (''Pithecophaga jefferyi''). The Steller's sea eagle is endemic to Northeast Asia, where it lives in Russia, Korea, Japan, China, and Taiwan. Steller's sea eagle lives in coastal northeastern Asia and mainly preys on fish and water birds. The Kamchatka Peninsula in Far Eastern Russia is known for its relatively large population of these birds; about 4,000 of these eagles live there. Steller's sea eagle is listed as vulnerable on the International Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bald Eagle
The bald eagle (''Haliaeetus leucocephalus'') is a bird of prey found in North America. A sea eagle, it has two known subspecies and forms a species pair with the white-tailed eagle (''Haliaeetus albicilla''), which occupies the same niche as the bald eagle in the Palearctic. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting. The bald eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down upon and snatches from the water with its talons. It builds the largest nest of any North American bird and the largest tree nests ever recorded for any animal species, up to deep, wide, and in weight. Sexual maturity is attained at the age of four to five years. Bald eagles are not actually bald; the name derives from an older meaning of the word, "white headed". The adult is mainly brown with ...

Pallas's Fish Eagle
Pallas's fish eagle (''Haliaeetus leucoryphus''), also known as Pallas's sea eagle or band-tailed fish eagle, is a large, brownish sea eagle. It breeds in the east Palearctic in Kazakhstan, Russia, Tajikistan, Turkmenistan, Uzbekistan, Mongolia, China, India, Nepal, Bangladesh, Myanmar and Bhutan. It is listed as Endangered on the IUCN Red List. It is partially migratory, with Central Asian birds wintering among the southern Asian birds in northern India, and also further west to the Persian Gulf. Description The Pallas's fish eagle has a light sandy-brown hood and a whitish face. The wings are darker brown and the back rufous. The long, slender wings (particularly slender for a sea eagle) are rather dark brown underneath. The tail is black with a wide, distinctive white stripe. Juveniles are overall darker, cooler brown with no band on the tail but with several pale areas on the wing, including the underwing coverts and inner primaries. This results in underwings that have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Madagascan Fish Eagle
The Madagascar fish eagle (''Haliaeetus vociferoides'') or Madagascar sea-eagle (to distinguish it from the ''Ichthyophaga'' fishing-eagles), 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 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". Description The Madagascar fish eagle is a medium-sized sea eagle, long and with a wingspan of . The body and wings are dark brown, with a pale brown head and a white tail; the bill is blackish with a paler base, and the legs are pale grey. Males weigh , while the slightly larger females weigh .

African Fish Eagle
The African fish eagle (''Haliaeetus vocifer'') or the African sea eagle, is a large species of eagle found throughout sub-Saharan Africa wherever large bodies of open water with an abundant food supply occur. It is the national bird of Malawi, Namibia, Zambia, and Zimbabwe. As a result of its large range, it is known in many languages. Examples of names include: Vis Arend in Afrikaans, ''nkwazi'' in Chewa, ''aigle pêcheur'' in French, ''hungwe'' in Shona, ''inkwazi'' in isiZulu, and ''ntšhu'' (pronounced "ntjhu") in Northern Sotho. This species may resemble the bald eagle in appearance; though related, the two species occurs on different continents, with the bald eagle being resident in North America. Taxonomy The African fish eagle is a species placed in the genus ''Haliaeetus'' ( sea eagles). Its closest relative appears to be the critically endangered Madagascar fish eagle (''H. vociferoides''). Like all sea eagle species pairs, this one consists of a white-headed spec ...
