The bald eagle's recovery from near-extinction due to DDT poisoning is one of conservation's greatest triumphs, but ongoing threats including lead poisoning and habitat loss continue to affect the welfare of individual eagles and population health.
Individual eagle welfare is threatened by lead poisoning - a slow, painful death involving progressive neurological damage, paralysis, and eventual fatal respiratory failure. Eagles that survive lead poisoning after treatment often require extended rehabilitation, during which confinement causes significant stress to a species adapted to wide-ranging flight. Electrocution from power lines causes sudden death or severe burns requiring intensive veterinary care. Eagles that recover from severe injuries but cannot be released face lifetime captivity, which - while managed humanely at rehabilitation centers - represents a significant restriction of natural behavior for a highly mobile predator. The collision between human infrastructure and eagle biology continues to cause preventable suffering.
