We collected adult male common goldeneye (Bucephala clangula) near their time of arrival on wintering grounds (Nov-Dec) (n = 26) and just prior to spring migration (Feb-Mar) (n = 24) from the Upper Niagara River (UNR), New York, to identify and measure organochlorine contaminants in fat tissues. Detectable concentrations of polychlorinated biphenyl (PCB), dichlorodiphenyldichloroethylene (DDE), dieldrin, hexachlorobenzene (HCB), oxychlordane, and heptachlor epoxide (HE) were found in all adult birds. Polychlorinated biphenyl, dieldrin, HCB, and HE increased (P < 0.05) in adults between the 2 sample periods. In a group of hatching-year (HY) birds sampled in November-December (n = 27), organochlorine residues were less than those of adults from the same period (P < 0.001). Contaminants known to occur in prey items (e.g., crustaceans, gastropods, insects, pelecypods, fish, and annelids) are probably the major source of exposure for common goldeneye on the Niagara River.
