Nearly half of bald and golden eagles in the US have chronic lead poisoning, a study found. Of that sample, 47% of bald eagles and 46% of golden eagles had signs of chronic lead poisoning. The researchers estimated that lead poisoning slowed the annual population growth of bald eagles by 4% and golden eagles by 1%. Neither golden eagles nor bald eagles are endangered species. Up to 33% of bald eagles and up to 35% of golden eagles in the study showed signs of acute lead poisoning.
