The White-bellied sea eagle is a large diurnal bird of prey that breeds and hunts near water, and fish form around half of its diet. This bird has a white head, rump and underparts, and dark or slate-grey back and wings. In flight, the black flight feathers on the wings are easily seen when the bird is viewed from below. The large, hooked bill is a leaden blue-grey with a darker tip, and the eyes are dark brown. The legs and feet are yellow or grey, with long black talons (claws). Like many raptors, the female is slightly larger than the male. Immature birds have brown plumage, which is gradually replaced by white until the age of five or six years. 

These eaglets are probably arong 5 seeks old - just developing their adult plumage. The mortality rate is high amongst newly-independent young birds, but if juveniles survive to breeding age they may live for up to 30 years
