Lead Poisoning Harming Eagles in Northwest Montana

This juvenile, male, golden eagle was found by a landowner in East Radner suffering from lead poisoning. One of the most obvious side affects of lead poisoning is "balled" feet. He has responded very well to treatment and daily physical therapy, is eating very well and gaining strength every day. Thanks to these specially designed splints, the eagle is able to stand, walk and even perch on a low block. Photo credit FWP Montana Wild Wings Recovery Center in Kalispell has treated six bald eagles and one golden eagle with elevated lead levels in 2025. Of those, one bald eagle and the golden eagle succumbed to lead poisoning, one bald eagle remains in treatment, and four bald eagles have been successfully rehabilitated and released. Lead poisoning is a common cause of death for eagles in northwest Montana, following vehicle collisions. Of the 45 eagles tested at the center from 2017 to 2025, 55 percent showed lead levels above normal environmental levels. This year, two eagles had lead levels so high they were unreadable. Even low-level lead exposure can impair coordination for eagles, increasing the risk of fatal accidents, such as vehicle strikes. Eagles are exposed to lead primarily by scavenging carcasses and gut piles containing fragments from lead-based ammunition. Spikes in lead poisoning occur during and after the fall rifle hunting season, when lead-shot deer and elk remains are prevalent, and to a lesser extent in spring, when Columbian ground squirrels are targeted with lead bullets. Hunters can help reduce eagle deaths by switching to nonlead ammunition, such as copper. Please report any dead, injured, or sick eagles to the FWP Region 1 office at 406-752-5501.
