Common buzzards have recovered dramatically from persecution and organochlorine poisoning, with ongoing welfare threats from illegal killing and lead poisoning.
Buzzard recovery demonstrates that legal protection and persecution reduction can enable dramatic population increase. Individual buzzards illegally killed lose lives of significant length and social complexity - buzzards form long-term pair bonds and may live 25+ years. Lead poisoning causes prolonged neurological deterioration before death. The welfare case for complete prohibition of lead ammunition and effective anti-persecution enforcement is strong.
