Gypohierax angolensis (Palm-nut Vulture)

Wikipedia Abstract

The palm-nut vulture (Gypohierax angolensis) or vulturine fish eagle, is a large bird of prey in the family Accipitridae (which also includes many other diurnal raptors such as kites, buzzards and harriers, vultures, and eagles). It is the only member of the genus Gypohierax. Unusual for birds of prey, it feeds mainly on the fruit of the oil palm, though it also feeds on crabs, molluscs, locusts, and fish, and has been known to occasionally attack domestic poultry and bats.
