The Asian white-backed vulture has recently undergone a catastrophic population crash, which threatens the survival of this species. It is a medium-sized vulture, with the blunt talons and bare head that characterise this group of carrion-feeding birds. The wings are black, whilst the neck-ruff, rump and underwings are white. The bare head and neck are black and the bill is silver.
Family: ACCIPITRIDAE
Order: FALCONIFORMES

Previously abundant throughout southern Asia, the white-backed vulture had all but disappeared from South East Asia by the mid-20th century In contrast, this vulture remained fairly common on the Indian subcontinent until the late 1990s when populations underwent sudden and catastrophic declines throughout the region, prompting the species to be upgraded to Critically Endangered.
The use of drug Diclofenac to cattle is the major reason for the gradual decline of this species. Though the drug is restricted to use in the veterinary field, it is widely availabe for anybody without any prescribtion from the authorities in India.
