Organochlorine residues and eggshell measurements of tree swallows Tachycineta bicolor in Colorado

DeWeese, L.R.; Cohen, R.R.; Stafford, C.J.

Abstract:

Residues of 6 organochlorine compds. were detected in adult carcasses, 4 in eggs, 2 in brains, and one in nestlings of Colorado tree swallows (Tachycineta bicolor). DDE [72-55-9]accounted for 91% of total organochlorine compound residue in each of the 4 sample types. DDE was detected in 30 samples (94%) and DDT [50-29-3] in 2 samples (6%). Carcasses of breeding females and egg clutches had residues of 6 organochlorine compds. not found in nestling samples. Only residues of DDE were found in nestlings. DDT and DDE were the only organochlorine compds. recovered in brain samples. Measurements of tree swallow eggshells showed that unattended eggs were not significantly different from those of attended or historical eggs. The implications of the observed organochlorine compound contamination are discussed.
