Oriental White Ibis



Description

     The 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 IndiaBangladeshNepal and Sri Lankaeast up to Japan. It builds a stick nest in a tree and lays 2–4 eggs


Behavior, habitat and feeding

     It occurs in marshy wetlands inland and on the coast, where it feeds on various fishfrogs 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.


     It is a good learning phenomenon watching the ibises, though they are busy searching for snails and frogs in the fields, they still watch around them quite well. As we were inching close to the ibis, it used to watch at us and slightly walk away from us to keep a safe distance to fly. I am thankful to my great birding friends Ajith Kamath and Ranganath Bhat for making my Sunday a refreshing one.
