The world’s largest ibis now remains in lowland forest in northern and eastern Cambodia. It searches for food at secluded forest pools.
It is described as the largest ibis, about twice the size of the next-largest ibis species.
Shy by nature, it feeds at secluded forest pools far from villages. It breeds in the wet season, when it eats giant earthworms, eels and frogs.
Adults have dark grey-brown plumage, a dark hindcrown and nape, and pale grey wing-coverts with darker tips. The eyes are red and the legs light red.
Juveniles have short feathers on the hindcrown and hindneck, a shorter bill, and brown eyes.
