Organochlorine residues in starlings (Sturnus vulgaris) from 126 collection sites were monitored during the fall of 1974. DDE, DDT, polychlorinated biphenyls (PCB's), and benzene hexachloride were present in all samples. Dieldrin, heptachlor expoxide, hexachlorobenzene, and oxychlordane were present in approximately 97% of the samples. DDE, dieldrin, and PCB residues in starlings were significantly lower than they had been in 1972.
