Abstract

Lethal residues of polychlorinated biphenyls (PCBs) were determined experimentally in four species of wild birds (male common grackles (Quiscalus quiscula ), immature female red-winged blackbirds (Agelaius phoeniceus ), adult male brown-headed cowbirds (Molothrus ater ) and immature female starlings (Sturnus vulgaris)) given dietary dosage of 1,500 ppm of Aroclor 1254) until one-half had died, sacrificing the survivors, chemically analyzing the tissues, and comparing results in dead birds and survivors. For all species, residues of 310 ppm or higher in the brain showed increasing likelihood of death from PCB poisoning. Residues in dead birds did not differ among species except for starlings (Sturnus vulgaris ), which averaged slightly lower than the others. However, the species differed in the length of time to 50% mortality and in the levels of PCBs in brains at sacrifice.
