Lead ammunition fragments in carcasses and gut piles cause mass poisoning of scavenging wildlife including eagles, condors, and vultures, with major welfare and conservation implications.
Lead poisoning causes a prolonged and painful death in affected birds, with neurological symptoms including loss of coordination, inability to fly, and eventual organ failure. The problem is systemic: a single deer carcass or gut pile left after hunting can contain hundreds of lead fragments that persist in the environment. Condor recovery programmes have been significantly impeded by lead poisoning from ammunition. Non-lead ammunition is readily available and many hunters have voluntarily switched, but mandatory requirements are needed for comprehensive impact.
