Lead has long been documented as a serious environmental
hazard to eagles and other predatory, opportunistic, and
scavenging avian species. However, the degree to which
lead poisoning is prevalent in eagle populations is not well
understood. We analyzed blood from 178 Golden Eagles
captured on fall migration in Montana from 2006 to 2012
to determine blood lead levels (BLL). Of these, 58% (n =
103) of eagles had elevated BLL (> 10 μg/dl), 10% (n =
17) were exposed at a level considered clinical (> 60 μg/
dl), and 4% (n = 7) had BLL considered lethal (> 120 μg/
dl). Golden Eagles captured on carrion had higher BLL than
those captured using live bait, suggesting differences in BLL
may be due to variations in feeding habits among individuals.
Our findings suggest that migrant golden eagles in western
North America are susceptible to lead poisoning during fall
migration and furthermore, that scavenging behavior may
lead to this problem.
