Think of an eagle…what comes to mind? A large powerful bird of prey, swooping down and snatching up its next victim? Or maybe you imagine a beautiful and noble bird with very likable qualities. Actually, eagles are all of that and more. In the United States, the Bald Eagle is a symbol of justice, strength, and fairness. The Bald Eagle is after all, our national symbol. However, to the rest of the world the eagle may bring to mind many different images. That is because there are many different types of eagles. In fact there are about 59 different species of eagles throughout the world, and they can be found on every continent except Antarctica. Eagles are members of the bird family Accipitridae, and belong to several genera which are not necessarily closely related to each other. Most of the more than 60 species occur in Eurasia and Africa. Outside this area, just two species (the Bald and Golden Eagles) can be found in the United States and Canada, nine more in Central and South America, and three in Australia.
Eagles differ from many other birds of prey which] mainly by their larger size, more powerful build, and heavier head and beak. Even the smallest eagles, like the Booted Eagle (which is comparable in size to a Common Buzzard or Red-tailed Hawk), have relatively longer and more evenly broad wings, and more direct, faster flight. Most eagles are larger than any other raptors apart from the vultures. Species named as eagles range in size from the South Nicobar Serpent Eagle, at 500 g (1.1 lb) and 40 cm (16 in), to the 6.7 kg (14.7 lbs) Steller’s Sea Eagle and the 100 cm (39 in) Philippine Eagle. Like all birds of prey, eagles have very large hooked beaks for tearing flesh from their prey, strong muscular legs, and powerful talons. They also have extremely keen eyesight which enables them to spot potential prey from a very long distance. This keen eyesight is primarily contributed by their extremely large pupils which ensure minimal diffraction (scattering) of the incoming light. Eagles build their nests, called eyries, in tall trees or on high cliffs. Many species lay two eggs, but the older, larger chick frequently kills its younger sibling once it has hatched. The dominant chick tends to be the female, as they are bigger than the male. The parents take no action to stop the killing. Species

Major new research into eagle taxonomy suggests that the important genera Aquila and Hieraaetus are not composed of nearest relatives, and it is likely that a reclassification of these genera will soon take place, with some species being moved to Lophaetus or Ictinaetus. * Bonelli’s Eagle, the Booted Eagle and the Little Eagle have been moved from Hieraaetus to Aquila. * Either the Greater Spotted Eagle and Lesser Spotted Eagle should move from Aquila to join the Long-crested Eagle in Lophaetus, or, perhaps better, all three of these species should move to Ictinaetus with the Black Eagle. * The Steppe Eagle and Tawny Eagle, once thought to be conspecific, are not even each other’s nearest relatives.

Eagles in culture
The modern English name of the bird is derived from the Latin term aquila by way of the French aigle. The Latin aquila may derive from the word aquilus, meaning dark-colored, swarthy, or blackish, as a description of the eagle’s plumage; or from aquilo, the Latin version of Greek boreas, or north wind; however, aquilus and aquilo may just as well derive from aquila (or be unrelated) and the latter be of unknown origin. Old English used the term earn, related to Scandinavia’s ørn / örn. The etymology of this word relates it to Greek ornís, meaning “bird”, though other Indo-European languages (such as Welsh eryr or Russian orël / орёл) show that the meaning ‘eagle’ is older. The Greek word may be an old diminutive. The Albanian word for eagle is “shqiponje” deriving from the root “shqipe”, which means “eagle”. In Britain before 1678, eagle referred specifically to the Golden Eagle, with the other native species, the White-tailed Eagle, being known as the Erne. The modern name “Golden Eagle” for aquila chrysaetos was introduced by the naturalist John Ray. Eagles as national symbols

From this derives: * The late Byzantine Empire chose a two-headed golden eagle as its symbol. It is popularly that one head symbolised ancient Rome, and the other head symbolized “new Rome” at Constantinople. From this derives: * The two-headed eagle is the emblem of “Shqipëria” or Land of the Eagles, which is known in English as Albania (see The Tale of the Eagle for the legendary origin of the name)
* After the fall of Constantinople, the Russian Empire took the two-headed eagle as its own symbol. * After his crowning as the new Roman Emperor, Charlemagne adopted the ancient Roman eagle as his own symbol. The Holy Roman Empire born of his kingdom took the eagle, but the Habsburgs replaced the golden eagle by an imperial eagle. From this derives: * The Austrian Empire had a two-headed eagle as its symbol. After the abolition of Austria-Hungary, Austria took as its symbol a one-headed eagle in the modern coat of arms of Austria. * Prussia, and later Germany have used a black eagle as their national symbol. * The Spanish Catholic monarchs, Isabella and Ferdinand, used the eagle as a part of the royal shield representing Saint John the Evangelist. The eagle was again on the Spanish shield under the Francoist regime and the transition to Democracy (1939–1981). * The Seljuk Turks and Ottoman Turks used a double-headed eagle as coats-of-arms. Religion
The Moche people of ancient Peru worshiped the animal and often depicted eagles in their art. Despite modern and historic Native American practices of giving eagle feathers to non-indigenous people and also members of other tribes who have been deemed worthy, current United States eagle feather law stipulates that only individuals of certifiable Native American ancestry enrolled in a federally recognized tribe are legally authorized to obtain eagle feathers for religious or spiritual reasons. In Canada, poaching of eagle feathers for the booming U.S. market has sometimes resulted in the arrests of First Nations person for the crime. *
Garuda, the Vahana of Lord Vishnu
Garuda murthi in West Bengal, India
In Hindu religion, Garuda is a lesser Hindu divinity, usually the mount (vahanam) of Vishnu. Garuda is depicted as having the golden body of a strong man with a white face, red wings, and an eagle’s beak and with a crown on his head. This ancient deity was said to be massive, large enough to block out the sun. The eagle is also the patron animal of Zeus. In particular, Zeus was said to have taken the form of an eagle in order to abduct Ganymede, and there are numerous artistic depictions of the Eagle Zeus bearing Ganymede aloft, from Classical times up to the present.
