The recovery of white-tailed sea eagles across Europe is a conservation success story, but ongoing welfare threats from persecution, lead poisoning, and collision continue.
Sea eagle welfare harms include acute suffering from lead poisoning which causes progressive neurological deterioration, persecution through illegal poisoning that causes prolonged agonizing death, and trauma from collision with infrastructure. Surviving eagles with sublethal lead exposure suffer cognitive impairment affecting hunting success and survival. Conservation progress requires simultaneous welfare interventions: mandatory switch to non-lead ammunition, power line mitigation, and robust enforcement of persecution laws.
