Bioaccumulation of Mercury in Wilson’s Snipe from Alabama

Mercury is a persistent, toxic heavy metal that can bioaccumulate in organisms, causing diseases and other health problems. Wilson’s snipe (Gallinago delicata) feed primarily on aquatic invertebrates, which makes them prone to mercury bioaccumulation. In this study, we measured total mercury in Wilson’s snipe. Total mercury was measured in the feathers and muscle tissue. Mean concentration (ppm ± SE) of mercury was 1.33 (± 0.22) and 0.087 (± 0.03) in the feathers and muscle tissue, respectively. Mercury concentration was significantly higher in feathers than muscle. Our data indicate that Wilson’s snipe, an aquatic-invertebrate predator that bioaccumulates mercury from their environment may be a useful biological indicator for mercury.
