The black-headed ibis (Threskiornis melanocephalus), also known as the Oriental white ibis, Indian white ibis, and black-necked ibis, is a large wading bird native to the Indian Subcontinent. It is easily identified by its snow-white body plumage, which contrasts sharply with its naked, jet-black head and neck. Its long, thick, down-curved bill (also black) is a specialized tool for probing deep into mud for fish, frogs, and mollusks. Though often referred to as a wetland species, the black-headed ibis forages in a range of natural and man-made habitats. This species of ibis nests only during the rainy season.
