Lead poisoning

The first golden eagle in Yellowstone National Park to wear a tracking device is dead from lead poisoning.

In 2015, the town of Pinedale turned off its sodium silicate water treatment--a type of corrosion control that helps prevent lead contamination from old plumbing. The next year, dangerous levels of lead were found in one residence and at the town’s high school. The treatment has been turned back on, but residents want to know why it was shut off in the first place.

For years, no one could figure out why birds of prey were turning up with extremely high levels of lead poisoning. The issue made headlines when the newly reintroduced condor in California began dying off from lead exposure. Craighead Beringia South is a group of wildlife researchers in Kelly, Wyoming who were among the scientists who started studying the problem in other species, back in the early 2000’s.

Hunters who use lead bullets may be contributing to the lead poisoning of eagles and ravens. But a voluntary non-lead ammunition program on the National Elk Refuge in Jackson is helping to curb the problem.             

Back in 2010, the non-profit Craighead Beringia South gave away copper bullets to prove to hunters that the quality was as good or better than lead. Research biologist Ross Crandall says, hunters are natural conservationists and don’t want to contribute to the illness or death of scavengers feeding on their gut piles anyway.
