White-bellied Sea Eagle

White-bellied Sea Eagle
Flying Animal | White-bellied Sea Eagle | Haliaeetus leucogaster | The White-bellied Sea-Eagle is a large raptor that has long, broad wings and a short, wedge-shaped tail. It measures 75–85 cm in length, and has a wingspan of 180–220 cm. Females weigh between 2.8 and 4.2 kg, and are larger than the males, which weigh between 2.5 and 3.7 kg. The plumage of adult birds is predominantly white and grey. The head, breast and belly, and the feathering on the legs, are white. The back and upper surfaces of the wings are grey, although the wings have black tips. The undersides of the wings are greyish-black around the distal edges, with a smaller area of white along the leading edge. The tail is grey at the base, and has a white tip. The bill is bluish-grey with a blackish tip, the iris is dark brown, and the legs and feet are a cream colour.
The juveniles differ from the adults in appearance in having predominantly dark brown plumage on the upper parts, except for the creamy colouring on the head, and creamy markings over the rest of the upper parts. The underside of the body is a similar colour to the upper parts, but becomes paler with wear. The under side of the wing is patterned with a mixture of orange-buff, white, dark brown and dark grey. There is a gradual transition from the brown and cream plumage of juvenile birds to the white and grey plumage of the adults. This transition is completed across a series of moults, over a period of several years. The White-bellied Sea-Eagle is generally seen singly or in pairs, though it may occasionally congregate around sites where food is abundant.

Australia
The White-bellied Sea Eagle is listed under the marine and migratory categories which give it protected status under Australia's federal Environment Protection and Biodiversity Conservation Act 1999. As a mainly coastal species, it is vulnerable to habitat destruction in Australia's increasingly populated and urbanised coastal areas, particularly in the south and east of the country, where it appears to have declined in numbers. However, there may have been an increase in population inland, secondary to the creation of reservoirs, dams and weirs, and the spread of the introduced common carp (Cyprinus carpio). However, it is rare along the Murray River where it was once common. It is also listed as Threatened under Victoria's Flora and Fauna Guarantee Act (1988), with possibly fewer than 100 breeding pairs remaining in the state. On the 2007 advisory list of threatened vertebrate fauna in Victoria, the White-bellied Sea-eagle is listed as vulnerable.
