Eagles
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) vertebrate, 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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Golden Eagle
The golden eagle (''Aquila chrysaetos'') is a bird of prey living in the Northern Hemisphere. It is the most widely distributed species of eagle. Like all eagles, it belongs to the family Accipitridae. They are one of the best-known birds of prey in the Northern Hemisphere. These birds are dark brown, with lighter golden-brown plumage on their napes. Immature eagles of this species typically have white on the tail and often have white markings on the wings. Golden eagles use their agility and speed combined with powerful feet and large, sharp talons to hunt a variety of prey, mainly hares, rabbits, and marmots and other ground squirrels. Golden eagles maintain home ranges or territories that may be as large as . They build large nests in cliffs and other high places to which they may return for several breeding years. Most breeding activities take place in the spring; they are monogamous and may remain together for several years or possibly for life. Females lay up t ...

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] |
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 species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bateleur
The bateleur (; ''Terathopius ecaudatus'') is a medium-sized eagle in the family Accipitridae. It is often considered a relative of the snake eagles and, like them, it is classified within the subfamily Circaetinae.Kemp, A. C., G. M. Kirwan, and D. A. Christie (2020). ''Bateleur (Terathopius ecaudatus)'', version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. It is the only member of the genus ''Terathopius'' and may be the origin of the "Zimbabwe Bird", the national emblem of Zimbabwe. Adult bateleurs are generally black in colour with a chestnut colour on the mantle as well as also on the rump and tail. Adults also have gray patches about the leading edges of the wings (extending to the secondaries in females) with bright red on their cere and their feet. Adults also show white greater coverts, contrasting with black remiges in males, gray patches on the underwing primar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haliaeetus
A sea eagle or fish eagle (also called erne or ern, mostly in reference to the white-tailed eagle) is any of the birds of prey in the genus ''Haliaeetus'' in the bird of prey family Accipitridae. Taxonomy and evolution The genus ''Haliaeetus'' was introduced in 1809 by French naturalist Marie Jules César Savigny in his chapter on birds in the ''Description de l'Égypte''. The two fish eagles in the genus ''Ichthyophaga'' were found to lie within ''Haliaeetus'' in a genetic study in 2005, they were then moved accordingly. They are very similar to the tropical ''Haliaeetus'' species. A prehistoric (i.e. extinct before 1500) form from Maui in the Hawaiian Islands may represent a species or subspecies in this genus. The relationships to other genera in the family are less clear; they have long been considered closer to the genus '' Milvus'' (kites) than to the true eagles in the genus '' Aquila'' on the basis of their morphology and display behaviour;Brown, L. H, & Amadon, D. (196 ... [...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 phylo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Eagle
The black eagle (''Ictinaetus malaiensis'') is a bird of prey. Like all eagles, it is in the family Accipitridae, and is the only member of the genus ''Ictinaetus''. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia, as well as southeastern China. They hunt mammals and birds, particularly at their nests. They are easily identified by their widely splayed and long primary "fingers", the characteristic silhouette, slow flight and yellow ceres and legs that contrast with their dark feathers. Taxonomy and systematics The species name is spelt ''malayensis'' in most publications but the original spelling used by Temminck in his description uses the spelling ''malaiensis'' according to a 2011 finding of some of the original covers of the part publications leading to taxonomists applying the principle of priority and rejecting any later spelling emendations.

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 ...

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 ...

South Nicobar Serpent Eagle
The Great Nicobar serpent eagle (''Spilornis klossi''), also known as the South Nicobar serpent eagle, is a species of bird of prey in the family Accipitridae. It is probably the smallest known eagle, with a weight of about , a wingspan of and a body length of about .Clark, W.S., G. M. Kirwan, and D. A. Christie (2020). ''Nicobar Serpent-Eagle (Spilornis klossi)'', version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. It is endemic to forest on the Indian island of Great Nicobar. It is threatened by habitat loss. All major authorities now treat the Great Nicobar serpent eagle as a species, but in the past it was sometimes considered a subspecies of ''S. minimus''. Today ''S. minimus'' is either considered a subspecies of the crested serpent eagle or a monotypic species from the central Nicobar Islands, the Central Nicobar serpent eagle The crested serpent eagle (''Spil ...

Bird 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 frog ...
