Eagles :: essays research papers

Eagle, common name for a number of diurnal birds of prey, some of which are the largest members of their family which also includes kites, hawks, buzzards, and certain vultures. The name eagle is somewhat loosely applied, as several of the groups are not particularly closely related to one another, and some birds called hawks are larger than some called eagles. IIGOLDEN AND RELATED EAGLES The golden eagle is distributed through most of the northern hemisphere. 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 true 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 body 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 pale 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 may 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 occasionally three. They are heavily marked with blotches and spots of various shades of brown.
