Mercury is an ubiquitous environmental contaminant that affects the health of birds and other wild animals. Two varieties of songbird -- zebra finch and European starling -- were found to shed mercury accumulation with their feathers in a recent study.
During a molt, both species quickly eliminated mercury from their blood and significantly reduced mercury concentrations in other tissues. This, coupled with a migration out of contaminated sites, may help birds deal with exposure to environmental toxins.
