O. Stanley 1976 5 June Herb Martyr Dam, Chiricahua Mts., Cochise Co., Arizona Larry Pizzo, Dave Kroline & Lawrence Frank and I arrived in Cave Creek Canyon in the Chiricahuas at about 5 pm, having driven from Lubbock and the mammal meetings via the Sacramente Mts and White Sands. After checking in at the AMNH field station, we drove up to Herb Martyr Dam ~2-3 miles NW up the canyon. Mixed pine-oak-yucca "forest" which reminds me very much of the sand hill scrub-oak-pine - palmetto forests in the southeast. We waited until the technicians left before setting up the net with poles tied to the railings of the fence on the dam. 1st bats seen ~8:30pm, a few minutes before the net was finally up. Captured 2 Eptesicus fairly soon, then a fall off in activity. Larry and I took another 30' net on the 2 remaining poles, stretched it across the water and tried slowly walking it down towards the dam, with no effect. Finally, at 10:15 pm, the last bat, Lasiorus cinereus, was caught. The lasiorus was quite vocal hissing & spitting to beat the band. Walking near the box he was in would set him off
