Status and conservation:

The red-headed vulture global population is estimated to number 3,500 to 15,000 individual birds.
The Indian vulture population declined by 90% mainly due to toxicity from diclofenac present in carcasses of cattle. The drastic reduction in the wild ungulate population, reduced availability of feed and increased human activity in the habitat are the threats for their survival.
The IUCN (International Union for Conservation of Nature) has categorized and evaluated these bird species and has listed them as "Critically Endangered".
