Turkey vultures are vital ecosystem cleaners often persecuted despite their ecological importance and the welfare harms of secondary poisoning.
Turkey vultures poisoned by lead shot from carcasses suffer progressive neurological deterioration including weakness, inability to fly, and eventually paralysis and death. They are slow to die from lead poisoning, suffering over extended periods. Rodenticide secondary poisoning causes similar internal hemorrhaging seen in raptors. Their ecological role in disease prevention makes their welfare and conservation inseparable concerns.
