Most of the more than 61 species occur in Eurasia and Africa.del Hoyo, J.; Elliot, A. & Sargatal, J. (editors). (1994). Handbook of the Birds of the World Volume 2 : New World Vultures to Guineafowl. Lynx Edicions. ISBN 8487334156 Outside this area, just two species (the Bald Eagle|Bald and Golden Eagle s) can be found in the United States and Canada, nine more in Central and South America, and three in Australia. Many different species of eagle are found in the Philippines .
Description
Eagles are large, powerfully built birds of prey , with a heavy 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. (Despite reduced size in aerodynamic feathers) Most eagles are larger than any other raptors apart from some vulture s. Species named as eagles range in size from the South Nicobar Serpent Eagle , at 500 g (1.1& nbsp;lb) and 40& nbsp;cm (16& nbsp;in), to the 6.7& nbsp;kg (14.7& nbsp;lbs) Steller's Sea Eagle and the 100& nbsp;cm (39& nbsp;in) Philippine Eagle . Like all birds of prey, eagles have very large hooked beak s for tearing flesh from their prey, strong muscular legs, and powerful Claw|talons . The beak is typically heavier than most other birds of prey. They also have extremely keen eyesight which enables them to spot potential prey from a very long distance.cite journal|last=Shlaer|first=Robert|date=1972-05-26|title=An Eagle's Eye: Quality of the Retinal Image|journal=Science|volume=176|issue=4037|pages=920–922|publisher=|doi=10.1126/science.176.4037.920|url= http://www./920? ck=nck|accessdate=2007-11-20|pmid=5033635 This keen eyesight is primarily contributed by their extremely large pupils which ensure minimal diffraction (scattering) of the incoming light.
Eagles normally build their nests, called Bird nest|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.cite book | last = Grambo | first = Rebecca L | title = Eagles | year = 2003 | location = | publisher = Voyageur Press | isbn =9780896583634 |language = |page = 32 cite journal | last= Stinson | first= Christopher H | coauthors= | month= Dec | year=1979 | title= On the Selective Advantage of Fratricide in Raptors | journal= Evolution | volume= 33 | issue = 4 |language = | pages= 1219& ndash; 1225 | url = | doi =10.2307/2407480
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 .cite journal|last=Lerner|first=H. R. L.|coauthors=D. P. Mindell|year=2005|title=Phylogeny of eagles, Old World vultures, and other Accipitridae based on nuclear and mitochondrial DNA|journal=Molecular Phylogenetics and Evolution|pmid=15925523|issue=2|pages=327–346|doi=10.1016/j.ympev.2005.04.010|volume=37
Bonelli's Eagle , and the Booted 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 conspecificity|conspecific , are not even each other's nearest relatives.

Eagles in culture
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 / ????) 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 .
