Red-naped Ibis, Pseudibis papillosa, also known as Indian Black Ibis or Black Ibis is a species of birds which are normally found in the plains of the Indian Subcontinent. The Red-naped Ibis is similar to the Glossy Ibis but is much bigger in size and has a red nape. Also the coloration is entirely different from that of the Glossy Ibis. With a good view, this species can not be mistaken with similar species.
I have seen Red-naped Ibis only in India. The first time I saw this species in 2012 from Koonthakulam Bird Sanctuary where a good number of them were present.
