The largest species of eagle is the harpy eagle (Harpia harpyja) of tropical forests of South America. This species mostly feeds on monkeys and large birds. The Philippine monkey-eating eagle (Pithecophaga jefferyi) and New Guinea harpy eagle (Harpyopsis novaguineae) are analogous species in Southeast Asia.
The sea eagle or white-tailed eagle (Haliaeetus albicilla) is a widespread species that breeds in coastal habitats from Greenland and Iceland, through Europe, to Asia. This species has a dark-brown body and white tail. Another fishing eagle (H. vocifer) breeds in the vicinity of lakes and large rivers in Africa.
The imperial eagle (Aquila heliaca) and spotted eagle (A. clanga) are somewhat smaller versions of the golden eagle, breeding in plains, steppes, and other open habitats from central Asia to Spain and northwestern Africa. These birds tend to eat smaller-sized mammals than the golden eagle.
The short-toed or snake eagle (Circaetus gallicus) breeds extensively in mountainous terrain in southern Europe and southwestern Asia. This species feeds on small mammals and snakes. Because it predates on large numbers of poisonous vipers, the short-toed eagle is highly regarded by many people living within its range.
The black eagle (Ictinaetus malayensis) is a species of tropical forest, ranging from India and southern China to the islands of Java and Sumatra in Indonesia.
