Three species of south Asia's vultures are threatened with extinction. The White-rumped Vulture was so abundant in India in the 1980s that it was probably the most common large bird of prey in the world. Only one in a thousand now survives, a 99.9% decline for this species. All three species - White-rumped, Indian and the Slender-billed Vulture - have declined by more than 97% since the early 1990s. This shocking decline is because of a veterinary drug, diclofenac, which is toxic to any vulture that feeds on the carcass of recently treated cattle.
