Eagles are large birds of prey which are members of the bird family Accipitridae, and belong to several genera which are not necessarily closely related to each other.
Most of the more than 60 species occur in Eurasia and Africa.
Outside this area, just two species (the Bald and Golden Eagles) can be found in the USA and Canada, nine more in Central and South America, and three in Australia. 
Eagles are differentiated from other birds of prey mainly by their larger size, more powerful build, and heavier head and bill. Even the smallest eagles, like the Booted Eagle (which is comparable in size to a Common Buzzard or Red-tailed Hawk), have relatively longer and more evenly broad wings, and more direct, faster flight. 
Most eagles are larger than any other raptors apart from the vultures. The species called eagle can range in size from the Spillovers serpent-eagles, which typically weigh about 500 grams (1.1 pounds) and measure 45 cm (18 in), to the 6.5-kg, 1-meter Harpy Eagle, though the Philippine Eagle and the Steller's Sea-Eagle are of similar size.
