I surveyed for Townsend's big-eared bat (Plecotus townsendii) during two seasons (summer, winter) in suitable habitat on the Nez Perce National Forest and surrounding areas. A total of 54 mines, 13 buildings, 7 caves, 17 bridges, and 3 mist net sites were checked for bats. I found no P. townsendii and encountered only one site where I found evidence to suggest the species' presence in the recent past. After the survey was completed, I received one additional sighting on the Salmon River between the Nez Perce and Payette National Forests. I encountered seven other bat species during this work: 1) Eptesicus fuscus, the big brown bat; 2) Lasionycteris noctivagans, the silver-haired bat; 3) Lasiurus cinereus, the hoary bat; 4) Myotis evotis, the long-eared myotis; 5) M. lucifugus, the little brown bat [myotis]; and 6) M. volans, the Yuma myotis.
