Changeable Hawk Eagle is well established in Singapore. Its name reflects its occurrence in two different colour morphs – dark and light. It is a mid-sized raptor and a forest edge bird, with typically broad wings and a relatively small wingspan. It feeds on small- to large-sized birds, mammals – up to the size of small macaques, and reptiles.
White-bellied Sea Eagle is one of Singapore’s largest native raptor. It is seen frequently gliding over reservoirs and woodland areas and adult birds can be identified easily by their pure white lower bodies. It hunts fish, sea snakes, terrapins, frogs, rats and fruit bats.
Brahminy Kite is a highly adaptable raptor. It is common in Singapore and distinguished easily by a contrasting combination of an auburn-brown body with a grey-white head. Unlike other kites, it has a round, instead of a forked, tail. It feeds mostly on garbage from the surface of the sea. It also eats small crustaceans, frogs, rats, shellfish and fish.
Black-winged Kite is a medium-small raptor found mostly in grassland areas. It can be recognised by its red eyes and its light grey plumage that has a black patch on each wing. It hunts usually from a perch but is also capable of hovering like the kestrel species. In this, it is unique among kite species. It feeds mostly on rodents and insects.
