The white-rumped vulture was once India’s most common vulture — and perhaps the most numerous large bird of prey in the world. But between the mid-1990s and 2006, its population plummeted by 99.9%, and it’s now considered critically endangered.

The palm-nut vulture is unusual among vultures, in that about 70% of its diet is vegetarian — mostly consisting of palm nut fruits. It was once called the "vulturine fish eagle”, because of its eagle-like appearance and the way in which it hunts; swooping to the water's surface to grab fish.
