Vultures are among the world's most endangered bird groups, facing catastrophic population declines from poisoning, diclofenac, and persecution — with severe ecological and individual welfare consequences.
Individual vulture welfare is threatened primarily by human-mediated poisoning. Diclofenac poisoning causes progressive visceral gout and kidney failure — a painful death taking days. Lead poisoning causes neurological deterioration including loss of coordination, inability to fly, and progressive weakness before death. Deliberate poisoning of carcasses to kill predators, with vultures as collateral victims, is widespread in parts of Africa and accounts for enormous mortality. Electrocuted vultures suffer severe burns and often fatal injuries. Conservation interventions — vulture restaurants providing safe, uncontaminated food sources, lead ammunition bans, and power line marking — directly reduce this suffering for individual birds while also protecting populations.
