Despite successful population recovery, bald eagles continue to suffer and die from lead poisoning through scavenging carcasses containing spent lead rifle ammunition.
Bald eagles poisoned by lead suffer progressive neurological deterioration over days to weeks. Initial signs include loss of coordination and inability to fly. As poisoning advances, eagles become unable to hunt, leading to starvation combined with neurological damage. Seizures occur in severe cases. Wildlife rehabilitation centres treat hundreds of lead-poisoned eagles annually. The voluntary and mandatory transition to non-lead ammunition in areas where eagles scavenge carcasses is the most direct welfare intervention available.
