The crested ibis (Nipponia nippon) is a medium-sized threskiornithid, 55–79 cm long with a wingspan near 140 cm and a weight of 1.4–1.9 kg. It is white, acquiring a grey-black wash on head, neck and wings in the breeding season, and has a bare red face, a long downcurved bill and red legs. Formerly widespread in East Asia, the wild population fell to seven birds at Yangxian, Shaanxi, in 1981. It feeds on loach, frogs, crabs and insects in rice paddies and streams and nests in tall trees. The IUCN lists it Endangered.
