Red-headed Vulture

Red-headed Vulture (Sarcogyps calvus)

The Red-headed Vulture is a large scavenging bird distinguished by its bright red head and neck, contrasting with dark brown to black plumage. Adults measure 76-86 cm in length with a wingspan reaching 2.6 meters. As an obligate scavenger, this species plays a crucial ecological role by consuming carrion and preventing disease spread through rapid carcass disposal.

Historically distributed across South and Southeast Asia, the Red-headed Vulture inhabits subtropical and tropical dry forests, woodland savannas, and agricultural landscapes. Its range extends from the Indian subcontinent through Myanmar, Thailand, Cambodia, Laos, and Vietnam, with small populations in Malaysia and southern China.

The species has experienced catastrophic population declines, primarily due to diclofenac poisoning—a veterinary anti-inflammatory drug that causes fatal kidney failure in vultures consuming treated livestock carcasses. Habitat loss through deforestation and agricultural expansion compounds these pressures. Additionally, declining availability of wild ungulate carcasses and increased use of veterinary drugs in livestock further threaten remaining populations.

Conservation efforts include diclofenac bans in several range countries, promotion of vulture-safe alternatives like meloxicam, establishment of vulture restaurants providing safe food sources, and captive breeding programs in India and Cambodia. Protected area networks help preserve critical nesting and foraging habitats.

Despite conservation interventions, the Red-headed Vulture continues declining across most of its range. Recovery remains challenging due to the species' slow reproductive rate, ongoing illegal diclofenac use, and persistent habitat pressures. Long-term survival depends on sustained enforcement of drug regulations and landscape-scale habitat protection.
