Philippine Eagle, Pithecophaga jefferyi in Southern Philippines.

Wedge Tailed Eagle in Australia.
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.[3]

[edit] 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; 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, 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.

[edit] Eagles as national symbols

Eagles have been used by many nations as a national symbol.
Historic uses:

[edit] Religion

The Moche people of ancient Peru worshiped the animal and often depicted eagles in their art.[5]
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.[6] 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.[7]
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 (see illustrations in the Ganymede (mythology) page.)
