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. Most eagles are larger than any other raptors apart from the vultures.
Eagles build their nests, called eyries, in tall trees or on high cliffs.
