| Abstract | Seventy-two Neotropical migrant pass rines were analyzed for the presence of 17 organochlorine pesticide residues (aldrin; alpha-BHC; beta-BHC; gamma-BHC; delta BHC; p,p' -DDD; p,p' -DDE; p,p' -DDT; dieldrin; endosulfan I; endosulfan II; endosulfan sulfate; endrin; endrin aldehyde; heptachlor~ heptachlor epoxide; methoxychlor) using standard method ofgas chromatography applied to bird tissues. Individuals were colI eted along the Mississippi River during May 1996 and represent 11 species (Catharus ustulatus; Geothlypi trichas; Protonotaria citrea; Mniotilta varia; Contopus virens; Dendroica petechia; Ernpidonax minimus; Passerina cyanea; Myiarchus crinitus; Vireo gilvus). The contaminants most frequently detected were p,p' -DDE, dieldrin., and heptachlor epoxide. No significant difference was found between male and female birds, or between birds that wintered in one of two broad habitat types. Levels of all three pesticides, however, were significantly higher for those birds that predominantly winter in Northern South America than for those birds that predominantly winter in Central |
