  <dc:description>&lt;div id="Abs1-section" class="c-article-section"&gt;&lt;div id="Abs1-content" class="c-article-section__content"&gt;&lt;p&gt;Mercury is a persistent, biomagnifying contaminant that can cause negative behavioral, immunological, and reproductive effects in wildlife and human populations. We examined the role of wetland water-management on mercury bioaccumulation in songbirds and ducks at Kellys Slough National Wildlife Refuge Complex, near Grand Forks, North Dakota USA. We assessed mercury concentrations in blood of wetland-foraging songbirds (80 common yellowthroats [&lt;i&gt;Geothlypis trichas&lt;/i&gt;] and 14 Nelson’s sparrows [&lt;i&gt;Ammospiza nelsoni&lt;/i&gt;]) and eggs of upland-nesting ducks (28 gadwall [&lt;i&gt;Mareca strepera&lt;/i&gt;], 19 blue-winged teal [&lt;i&gt;Spatula discors&lt;/i&gt;], and 13 northern shoveler [&lt;i&gt;S. clypeta&lt;/i&gt;]) across four wetland water-management classifications. Nelson’s sparrow blood mercury concentrations were elevated (mean: 1.00 µg/g ww; 95% CL: 0.76–1.31) and similar to those reported 6 years previously. Mercury in songbird blood and duck eggs varied among wetland water-management classifications. Songbirds and ducks had 67% and 49% lower mercury concentrations, respectively, when occupying wetlands that were drawn down with water flow compared to individuals occupying isolated-depressional wetlands with no outflow. Additionally, songbirds within impounded and partially drawn-down wetland units with water flow had mercury concentrations that were 26–28% lower, respectively, than individuals within isolated-depressional wetlands with no outflow. Our results confirm that mercury concentrations in songbirds at Kellys Slough continue to be elevated and suggest that water-management could be an important tool for wetland managers to reduce bioaccumulation of mercury in birds.&lt;/p&gt;&lt;/div&gt;&lt;/div&gt;&lt;div id="cobranding-and-download-availability-text" class="note test-pdf-link"&gt;&lt;br&gt;&lt;/div&gt;</dc:description>
