The Bald Eagle is a highly recognizable eagle of approximately 75-105cm of body length. Life expectancy in captivity is even higher, reaching up to 60 years. It’s average life span in the wild is 20 or 30 years, though it can live up to 50 years. The Bald Eagle is a powerful flier, and soars on thermal convection currents. 10 Ma BP), if the most ancient fossil record is correctly assigned to this genus.

Both subspecies are separated from each other at approximately latitude 38° N, or roughly the latitude of San Francisco the northern subspecies reaches further south than latitude 38° N on the Atlantic Coast, where they occur in the Cape Hatteras area. The Bald Eagles of the northern range of distribution belong to the subspecies washingtoniensis, while the southern eagles belong to the leucocephalus- subspecies. The largest are Alaskan birds, where large females may exceed 7 kg and have a wingspan of over 2,5 m. The smallest specimens are those from Florida, where an adult male may barely exceed 2,3 kg, and a wingspan of 1,8 m. Bald Eagles are distinguishable from the Golden Eagle (Aquila chrysaetos) in that the former has a more protruding head with a larger bill and feathers which do not completely cover the legs. The distinctive white head and figure are developed a few years later, when it reaches sexual maturity. * Maximum velocity: It reaches speeds of up to 75 km/h when gliding and flapping. The toes are short and powerful with large talons, which help to snatch the fish out of the water. It is used repeatedly over many years and can weigh up to 2 t. * Nest: the eagle’s nest is called aerie. * Vision: stereoscopic, and eight times better than the vision of human beings. * Preferred prey: fish (many bald eagles live close to open water). * Wingspan and body weight of the females: up to 3 m 6 kg. * Wingspan and body weight of the males: up to 2,5 m 4 kg. The species was on the brink of extinction in the continental United States by the end of the 20th century, but now has a stable population and has been officially removed from the United States federal government’s list of endangered species. It is most recognizable as the national bird and symbol of the United States of America. The Bald Eagle (Haliaeetus leucocephalus), is a bird of prey found in North America.
