Bald eagles have recovered from near-extinction due to DDT, but face ongoing welfare threats from lead poisoning and power line collisions. Understanding these threats guides effective interventions.
Bald eagle welfare is threatened primarily by secondary lead poisoning — eagles that feed on deer gut piles containing lead shot fragments accumulate sub-lethal doses causing neurological impairment, weakness, and eventual death. Lead poisoning causes prolonged suffering before death and is entirely preventable through hunter adoption of lead-free ammunition. Power line electrocution causes sudden death or severe wing injuries requiring rehabilitation care. Raptor rehabilitation centers treat hundreds of lead-poisoned and electrocuted eagles annually — the welfare burden is substantial and ongoing. The solutions are clear: lead-free ammunition for hunting and retrograde power pole insulation in eagle territories.
