Description

A medium-sized stork, Anastomus oscitan is commonly known as the Asian openbill. It inhabits wetland habitats including shallow estuarine marshes, lakes with a brackish water and flooded fields which are agricultural areas that serve as rice paddies. Both sexes are similar. The species has pale white or grey plumage with black wings and a forked black tail. It also has long pinkish to red legs and feet and dull, yellow-grey colour bill. The juvenile has brown tinge head, instead of white or pale grey in adulthood. The bill is dark grey with lower mandible almost straight and the gap forms later.

The Asian openbills are carnivores. It feeds mainly on apple snails, but it also consumes frogs, crabs, large insects, and other small aquatic animals. They typically feed alone but may form flocks in areas saturated with food. The gap in the bill allows good grasp of the snail’s shell. It extracts snail from the shell, with the pointed lower mandible.
