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, 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 ( ...

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, agricultu ...

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 phylo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 smalle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
