tracking overwintering areas of fish-eating birds to identify mercury exposure.	migration patterns are believed to greatly influence concentrations of contaminants in birds due to accumulation in spatially and temporally distinct ecosystems. two species of fish-eating birds, the double-crested cormorant (phalacrocorax auritus) and the caspian tern (hydroprogne caspia) breeding in lake ontario were chosen to measure the impact of overwintering location on mercury concentrations ([hg]). we characterized (1) overwintering areas using stable isotopes of hydrogen (δ(2)h) and ban ...	2015	25514043
contamination of mercury during the wintering period influences concentrations at breeding sites in two migratory piscivorous birds.	many aquatic fish-eating birds migrate long distances and are exposed to different mercury concentrations ([hg]) during their annual cycle. here we examined the importance of migration on [hg] in two colonial migratory fish-eating bird species. we determined temporal trends of [hg] and stable isotopes of carbon (δ(13)c) and nitrogen (δ(15)n) during the annual cycle in double-crested cormorants (phalacrocorax auritus) and caspian terns (hydroprogne caspia) breeding in lake ontario by a repeated s ...	2014	25380025
