The Red-naped Ibis also known as the Indian Black Ibis or just the Black Ibis (Scientific name: Pseudibis papillosa), is a species of ibis found in parts of the Indian Subcontinent. It has a curlew-like long down-curved bill, a black head with a patch of crimson, and a white patch near the shoulder. This largish black bird is found at lakes, in marshes, in riverbeds and on irrigated farmland—it is not as aquatic as many other species of ibis. It is gregarious and generally forages on margins of wetlands in small numbers. (Wiki). Clicked at Koothankulam Bird Sanctuary in April/2015.
