The bald eagle (Haliaeetus leucocephalus) is a bird of prey found in North America. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting. The bald eagle is an opportunistic feeder which subsists mainly on fish, which it swoops down and snatches from the water with its talons. It builds the largest nest of any North American bird and the largest tree nests ever recorded for any animal species, up to 4 m deep, 2.5 m wide, and 1 metric ton in weight. Sexual maturity is attained at the age of four to five years. Bald eagles are not actually bald; the name derives from an older meaning of the word, "white headed". The adult is mainly brown with a white head and tail. The sexes are identical in plumage, but females are about 25 percent larger than males. The beak is large and hooked. The bald eagle is the national bird of the United States of America. The bald eagle appears on its seal. Populations have since recovered, and the species was removed from the U.S. government's list of endangered species on July 12, 1995 and transferred to the list of threatened species.(wikipedia)
