Bald eagles show signs of widespread lead poisoning
The resurgence of bald eagles has been heralded as one of the great conservation successes in the U.S. But a study suggests lead is stunting population growth.

Bald eagles, the centuries-old symbol of the United States, show signs of widespread poisoning from one of the country’s most pernicious pollutants: lead.
Nationwide, bald and golden eagles are continually exposed to the toxic heavy metal, according to research that tested more than 1,200 eagles from Alaska to Florida.
The study, which was published Thursday in the journal Science, evaluated eagles in 38 states, testing their bones, feathers, livers and blood for lead. Researchers found that 46 percent of bald eagles and 47 percent of golden eagles had chronic lead poisoning.
