Abstract:

Surveys for great gray owls were conducted from April through July 1989 on the Island Park, Ashton, and Teton Basin Ranger Districts (RD) of the Targhee National Forest (NF) . Surveys consisted of nocturnal playback of recorded great gray owl calls in areas on these ranger districts where owls had historically been heard or seen. Daytime searches for nests were conducted in areas where owls were heard in nocturnal surveys or in areas where great gray owls were sighted. Although we were unable to confirm any successful nests on the Targhee NF in 1989, we did locate two new suspected great gray owl nests on the Island Park RD and one on the Teton Basin RD. We also compiled records of great gray owls which we heard or sighted during our 1989 surveys . In addition, we summarized knowledge of historic nests sites and areas where young birds have been sighted in the past on these ranger districts. Lastly, we have made several recommendations for future studies and management of great gray owls on the Targhee NF.
