It’s been nearly 300 years since lead was first discovered in Missouri.

But the element's important role in the state's economy may come at a price to another natural resource. Scientists are planning to study the health effects of lead on local songbird populations.

The research, conducted by biologists at Southeast Missouri State University and the University of Missouri-Columbia, will take place in the Southeast Missouri Lead District, which contains the world’s largest deposits of galena, an important source of lead.

According to surveys by scientists and avid bird-watchers, many songbird species are declining in the U.S. Losing the birds that provide a natural soundtrack in our backyards is a critical environmental issue, since they also serve to control insect populations and as pollinators.
