Steller's sea eagle

Steller's sea eagle (Haliaeetus pelagicus), also known as Pacific sea eagle or white-shouldered eagle, is a very large diurnal bird of prey in the family Accipitridae. It was described first by Peter Simon Pallas in 1811. No subspecies are recognised. A sturdy eagle, it has dark brown plumage with white wings and tail, a yellow beak, and yellow talons. Typically, it is the heaviest eagle in the world, at about 5 to 10 kg (11 to 22 lb), but in some standard measurements, may be ranked below the harpy eagle (Harpia harpyja) and the Philippine eagle (Pithecophaga jefferyi). Steller's sea eagle females are bigger than males. The Steller's sea eagle is endemic to coastal northeastern Asia, where it lives in Russia, Korea, Japan, China, and Taiwan. It mainly preys on fish and water birds. The Kamchatka Peninsula in Far Eastern Russia is known for its relatively large population of these birds; about 4,000 of these eagles live there.[5] Steller's sea eagle is listed as vulnerable on the International Union for Conservation of Nature's Red List (IUCN Red List) of threatened species.
