The White-bellied Sea-eagle (Haliaeetus leucogaster) and also known as the White-bellied Fish-eagle or White-breasted Sea Eagle, is a large bird of prey in the family Accipitridae which also includes many other diurnal raptors such as kites, buzzards and harriers.
It is resident from India through southeast Asia to Australia on coasts and major waterways. This large eagle is very distinctive. The adult has white head, breast underwing coverts and tail. The upperparts are grey and the black underwing flight feathers contrast with the white coverts. The tail is short and wedge-shaped as in all Haliaeetus species.).

Description
White-bellied Sea-eagles are a common sight in coastal and near coastal areas of Australia. Birds form permanent pairs that inhabit territories throughout the year. Their loud "goose-like" honking call is a familiar sound, particularly during the breeding season. Birds are normally seen, perched high in a tree, or soaring over waterways and adjacent land.
In addition to Australia, the species is found in New Guinea, Indonesia, China, south-east Asia and India.

The White-bellied Sea-eagle feeds mainly off aquatic animals, such as fish, turtles and sea snakes, but it takes birds and mammals as well. It is a skilled hunter, and will attack prey up to the size of a swan. They also feed on carrion such as sheep and fish along the waterline. They harass smaller birds, forcing them to drop any food that they are carrying. Sea-eagles feed alone, in pairs or in family groups.
