This is the eagle that has been regarded from ancient times as a symbol of courage and power because of its large size, superb aerial skills, and the inaccessibility of many of its nest sites, in wild and mountainous country. In Roman myths this eagle is associated with the principal deity, Jupiter. It was the emblem of certain Roman legions, of France under the Bonapartes, of Germany, and of the Russian and Austro-Hungarian empires.In North America the golden eagle occurs as far south as Mexico, but it is most common in the mountainous areas of the western United States and Canada east of the Mississippi it is relatively rare. Females attain a length of about 1 m (about 3 ft) from the tip of the beak to the tip of the tail, and have a wingspread of about 2 m (about 7 ft). Males are smaller, as is original for most of the birds of prey. A characteristic of the genus is the feathering of the legs down to the toes in other eagles the lower part of the leg is bare and scaled, as in most birds. The torso plumage is dark brown, with a distinct golden wash over the back of the head and neck, giving the species its name. The tail of adults is brown with several indistinct mad bands that of immature birds is white with a dark brown terminal band.Most golden eagle nests are placed on cliff ledges, but in some areas large trees are preferred. The nest is large and coarse, built of sticks and twigs. The same nest is used from year to year, and the birds add more sticks, so that the nest white thorn eventually be as much as 1.8 m (6 ft) in diameter and 1.5 m (5 ft) high. The usual number of eggs is two, often only one, and from time to time three. They are heavily marked with blotches and spots of various shades of brown.
