BLACK-HEADED IBIS or Oriental White Ibis (Threskiornis melanocephalus) is a species of wading bird of the ibis family Threskiornithidae which breeds in the Indian Subcontinent and Southeast Asia from northern India, Bangladesh, Nepal and Sri Lanka east up to Japan. It
builds a stick nest in a tree and lays 2–4 eggs.
It occurs in marshy wetlands inland and on the coast, where it
feeds on various fish,frogs and other water creatures, as well as on insects. It walks about
actively on marshy land probing with its bill into soft mud and often feeds in
shallow water with its head momentarily submerged. Like storks and Spoonbills,
it lacks a true voice-producing mechanism and is silent except for peculiar
ventriloquial grunts uttered when nesting.
Adults are typically 75 cm long and white-plumaged, with some greyer areas on the wings. The bald head, the neck and
legs are black. The thick down curved bill is dusky yellow.In breeding,plumage
some slaty grey on scapulars and in wings and ornamental plumes at base of the
neck. Sexes are similar, but juveniles have whiter necks and a black bill. [INFO:WIKIPEDIA]
