Trace elements in lesser scaup (Aythya affinis) from the Mississippi flyway Trace elements in lesser scaup (Aythya affinis) from the Mississippi flyway
Previous research reported that concentrations of selenium in the livers of 88a??95% of lesser scaup from locations in Lake Erie, Lake St. Clair, and Lake Michigan, USA were either elevated (10a??33 A?g/g dry weight [dw]) or in the potentially harmful range (>33 A?g/g dw). In order to determine the geographic extent of these high selenium concentrations, we collected lesser scaup in...

Dioxins and congener-specific polychlorinated biphenyls in three avian species from the Wisconsin River, Wisconsin Dioxins and congener-specific polychlorinated biphenyls in three avian species from the Wisconsin River, Wisconsin
Sediments from the Wisconsin River, WI, USA are contaminated with 2,3,7,8-tetrachloro-p-dioxin (TCDD) and polychlorinated biphenyls (PCBs). Wet weight concentrations of TCDD and PCBs in eggs were at background levels and highest in the piscivorous hooded merganser (Lophodytes cucullatus; geometric mean=7 pg/g TCDD and 0.92 μg/g PCBs) and lowest in the omnivorous wood duck (Aix sponsa) (

Feeding habitat selection by Great Blue Herons and Great Egrets nesting in east central Minnesota Feeding habitat selection by Great Blue Herons and Great Egrets nesting in east central Minnesota
Great Blue Herons (Ardea herodias) and Great Egrets (Casmerodius albus) partitioned feeding habitat based on wetland size at Peltier Lake rookery in east central Minnesota. Great Blue Herons preferred large waterbodies (350 ha), whereas Great Egrets fed most often at small ponds (
