Granular dieldrin was applied by air to control Japanese beetles. Fourteen pheasants and 12 quail in four pens were exposed to the application. Nearby were wild quail, songbirds and starlings, but no pheasants. Later, remains of some wild birds were seen or reported. Nine quail and one starling "posted" at Ames had lesions similar to those in birds affected by toxemia. One quail that died before the operation and two pheasants that were examined did not show these lesions.
