The recovery of bald eagles from near extinction is an iconic conservation success — and welfare threats including lead poisoning remain significant.
Lead poisoning of bald eagles represents a preventable welfare harm that continues at scale despite the availability of non-toxic alternatives. Eagles dying from lead poisoning experience progressive neurological deterioration over weeks — loss of coordination, inability to fly or feed, and eventual death. This is not a brief acute welfare event but an extended period of incapacitation and suffering. The solution is known and available: copper ammunition fragments negligibly, does not persist in carcasses and gut piles, and is effective for hunting. The remaining barrier is hunter culture and cost — barriers that voluntary education programs and incentive schemes are beginning to address.
