Vulture populations across Africa and Asia have collapsed by up to 99% in some regions due to poisoning, traditional medicine demand, and persecution, with devastating ecosystem welfare consequences.
Vultures poisoned by diclofenac experience gout, organ failure, and prolonged suffering before death. Mass poisoning events from single carcasses can kill hundreds of birds simultaneously. The collapse of vulture populations has downstream welfare consequences for livestock herds and wildlife communities through increased disease transmission from decaying carcasses.
