Vultures are facing catastrophic declines globally from poisoning, collisions, and hunting, creating both conservation and individual welfare crises for these ecologically critical birds.
Vultures poisoned at carcasses die in convulsions from anticholinesterase compounds that cause muscle failure and respiratory arrest. Many birds die together at poisoned carcasses, creating mass mortality events. Vultures that ingest sublethal doses survive with neurological damage affecting flight and foraging ability. The loss of vultures from ecosystems allows carcasses to persist and spread disease — a cascading welfare harm to other species. Individual vultures are long-lived birds that form pair bonds and have strong cognitive complexity, making their individual deaths welfare-significant beyond their ecological role.
