Abstract
The effects of heptachlor seed treatments on birds in the vicinity of the Umatilla National Wildlife Refuge, Oregon and Washington, were investigated from 1978 to 1981. An egg was collected from each of 60 nests representing six species. Heptachlor epoxide (HE) residues were detected in 35 eggs and were particularly high (8?13 :g g-1) in a few eggs of the black-billed magpie, mallard, and ring-necked pheasant. These residues were within the range that induced reproductive problems in other species in the area. Diagnostically lethal residue levels (> 9 :g g-1) of HE were detected in the brains of nine birds (four species). Most of the avifauna in the area contained residues of HE and related compounds. Lindane, the replacement chemical for heptachlor, did not produce adverse effects in birds, and residues were not detected in either their eggs or brains.
