Eagle

Eagles are large birds of prey which are mainly found in Eurasia and Africa, though various species occur on all continents except for Antarctica. They come from the family Accipitridae. In Britain before 1678, Eagle referred specifically to the Golden Eagle (Aquila chrysaetos), the other native species, the White-tailed Eagle (Haliaeetus albicilla), being known as the Erne. The modern name "Golden Eagle" for Aquila chrysaetos was introduced by the naturalist John Ray.
==Bald Eagle==
The Bald Eagle (Haliaeetus leucocephalus), the US national bird, is the only eagle unique to North America. The Bald Eagle's scientific name signifies a sea (halo) eagle (aeetos) with a white (leukos) head. At one time, the word "bald" meant "white", not hairless. Bald Eagles are found over most of North America, from Alaska and Canada to northern Mexico. About half of the world's 70,000 bald eagles live in Alaska.
==Golden Eagle==
Golden Eagles range from sea level to 5,500 m altitude, occupying most of the open terrain of deserts, mountains, plateaus, and steppes in the Northern Hemisphere. They are not usually found in heavily forested areas. Golden Eagles living in the northern part of their range move south when the food supply becomes scarce in the winter.
