Vulture Welfare: Poisoning and Ecosystem Collapse

Vultures are among the most critically threatened bird groups globally, with populations collapsing from poisoning, both intentional and as secondary bycatch from carcasses treated with poisons targeting other species.

Key Facts

Four of the eight African vulture species are now classified as Critically Endangered by the IUCN
Diclofenac, a veterinary anti-inflammatory, killed an estimated 95-99% of vultures in South Asia before being banned from veterinary use in 2006
Intentional poisoning of vulture carcasses by poachers seeking to prevent the birds alerting rangers to illegal kills is a major mortality cause
Vultures provide essential ecosystem services by consuming carcasses that would otherwise spread disease to livestock and humans
The absence of vultures in South Asia following diclofenac poisoning led to a surge in feral dog populations and rabies transmission

Welfare Considerations

Vulture poisoning causes acute welfare suffering at population scale. Secondary poisoning from diclofenac-treated carcasses causes visceral gout, kidney failure, and prolonged death in affected birds. Intentional poisoning with carbofuran and other agricultural chemicals kills multiple birds per poisoned carcass, with lead poisoning from ingested bullets a chronic issue. The loss of vulture populations disrupts ecosystem function in ways that cause wider animal welfare impacts through disease transmission and carcass accumulation. Captive breeding and safe food provision programmes provide welfare-positive interventions for the most threatened populations.
