Lesser Fish Eagle
Icthyophaga humilis
The lesser fish eagle is a medium-sized bird of prey that is primarily gray-brown in colour with broad, blunt wings and coarse featherless legs. They are smaller than the similar Icthyophaga ichthyaetus (grey-headed fish eagle) and may often get confused with the similar species. The lesser fish eagle has a brown breast with white thighs and belly. They have a short, rounded tail with a long neck and a small head. Juvenile lesser fish eagles are similar in appearance to adults, although they have brown eyes whereas an adult has yellow. Adults have a wingspan reaching 1.

White-bellied Sea Eagle
Icthyophaga leucogaster
The white-bellied sea eagle 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 irides are dark brown. The cere is also lead grey. The legs and feet are yellow or grey, with long black talons (claws). Unlike those of eagles of the genus Aquila, the legs are not feathered. The sexes are similar. Males are 66–80 cm (26–31 in) long and weigh 1.8–3 kg (4.0–6.6 lb).
