Lead exposure in bald eagles

belotswinter

 
 During winter, bald eagles congregate in high numbers along the Upper Mississippi River and other large waterways in the states of Illinois, Iowa, Wisconsin and Minnesota. Researchers with U.S. Fish & Wildlife Service began a study in 2011 to assess lead exposure in bald eagles that inhabit the Upper Midwest including the Refuge. Thousands of bald eagles winter and hundreds of eagles nest in spring on the Refuge annually.

  • Information Sessions

     We will host a series of four information sessions to share the results of research demonstrating the relationship between lead ammunition and lead exposure in bald eagles. A presentation will begin at 6:15 p.m. at each session and will highlight the results of a two-year study which collected 168 deceased bald eagles from the Upper Midwest and examined them for lead exposure.
