Wetland water-management may influence mercury bioaccumulation in songbirds and ducks at a mercury hotspot data release

We examined the role of wetland water-management on mercury bioaccumulation in songbirds and ducks. This database contains records of mercury concentrations in blood of wetland-foraging songbirds (80 common yellowthroats [Geothlypis trichas] and 14 Nelson’s sparrows [Ammospiza nelsoni]) and eggs of upland-nesting ducks (28 gadwall [Mareca strepera], 19 blue-winged teal [Spatula discors], and 13 northern shoveler [S. clypeta]) across four wetland water-management classifications at Kellys Slough National Wildlife Refuge Complex, near Grand Forks, North Dakota USA.
