This article is about the bird. For other uses, see Eagle (disambiguation).

Eagles are large birds of prey which 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 USA and Canada, nine more in Central and South America, and three in Australia.

Description

Eagles are differentiated from other birds of prey mainly by their larger size, more powerful build, and heavier head and bill. 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. The species called eagle can range in size from the Spilornis serpent-eagles, which typically weigh about 500 grams (1.1 pounds) and measure 45 cm (18 in), to the 6.5-kg, 1-meter Harpy Eagle, though the Philippine Eagle and the Steller's Sea-Eagle are of similar size.

Like all birds of prey, eagles have very large powerful hooked beaks for tearing flesh from their prey, strong muscular legs, and powerful talons claws. 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 cause 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.

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.

Eagles in culture

[edit] The word

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.

Old English used the term Earn, related to Scandinavia's Ørn / Örn. The etymology of this word is related to Greek ornis, literally meaning "bird". In this sense, the Eagle is the Bird with a capital B.

In Britain before 1678, Eagle referred specifically to the Golden Eagle, 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 have been used by many nations as a national symbol.

Historic uses:

The eagle is the symbol used to depict John the Apostle in some Christian churches, whose writing most clearly witnesses the divinity of Christ. In art, John, as the writer of the Gospel, is sometimes depicted with an eagle. See Names of John.

The eagle is a sacred bird in some cultures and the feathers of the eagle are central to many religious and spiritual customs, especially amongst Native Americans in the United States and First Nations in Canada, as well as among many of the peoples of Meso-America. Some Native American peoples revere eagles as sacred religious objects and the feathers and parts of Bald and Golden Eagles are often compared to the Bible and crucifix. Eagle feathers are often used in various ceremonies and are used to honor noteworthy achievements and qualities such as exceptional leadership and bravery. In the cultures of the Northwest Coast, Eagle is also a supernatural being and also the ancestor and features in the heraldic crests of important clans known as totem poles.

The Moche people of ancient Peru worshipped 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.
