The White-bellied Fish Eagle ( Haliaeetus leucogaster) is the largest raptor in Singapore: with a wingspan of 50cm and body length of 70cm. White-bellied Fish Eagles are more commonly seen on warm early mornings riding the coastal thermals, holding their wings in a V-shape (other raptors hold them horizontally).
White-bellied Fish Eagles hunt prey that are found near the water surface mainly sea snakes, and fish. But other prey include birds, turtles, swimming crabs and even bats. They may also scavenge on refuse; a few haunt harbours for this purpose.
