Bald eagle recovery from DDT-driven near-extinction is a conservation success story, but eagles continue to face lead poisoning, vehicle strikes, and power line electrocution that impose welfare costs on individuals.
Bald eagle recovery is a conservation triumph that carries ongoing welfare challenges. The same scavenging behavior that allows eagles to exploit available food sources exposes them to lead fragments in hunter-killed carcasses and gut piles. Lead toxicity causes neurological impairment and a slow, disorienting death if untreated. Power line electrocution — caused by wingspan that can bridge conductors on older pole designs — kills eagles rapidly but represents preventable deaths through infrastructure modification. Wildlife rehabilitators who treat poisoned eagles provide direct welfare relief, but systematic prevention through non-lead ammunition campaigns and power line retrofitting is more impactful at scale.
