It has a long decurved bill with a pinkish to reddish brown colour. The skin on its face is usually a reddish color, and it also has long orange colored beak with pink legs. The total length of the ibis ranges between 45 and 50 cm.

Black-headed Ibis
Threskiornis melanocephalus
The black-headed ibis is one of several large waterbird species in south and south-east Asia, with adults measuring 65–76 cm in length. The white plumage is starkly contrasted against a conspicuous naked black neck and head, and black down-curved beak. Tails of adults bear light grey ornamental feathers that turn jet black during the breeding season. During the breeding season, bare patches under the wing turn blood-red. The head of some breeding adults gain a blueish tinge, or very rarely have a pink or bright red patch behind the neck.
