Atenee, H. 1992 August 8 at 0828h we found the signals from Natalus molossus # 88 and 14F at the same site, a small tuft of grass pushed down over the burrow - by them? Sunny & Warm. We waited until 0855h but they hadn't emerged. At 1004h I found C. molossus #3 on top of a huge Nestoma nest where he had been on June 28th, 500-750m 35W of yesterday's site. at ~1040h we found C. molossus F 12 under a boulder on a rock ledge in the general area we couldn't see her the last few days - she was in a hairpin coil of 3 equivalent length sections, w/ a food bulge >= 1/4 her body length, i.e., adult Nestoma or larger. By now I was exhausted due to trouble sleeping last night, so Bryan Jennings and Dave did the others. C. molossus #9 was still invisible behind the rat nest at 1103h. At 1145 h after a long walk they found C. molossus #13 hundreds of meters W. of yesterday, 75m N of the road, 15m E. and 50 m SSE of pole #1, coiled under a boulder, looking out, no reaction, in the shade. I went to Rodeo to do laundry, Fogdens arrived, and a great dinner of chiles rellenos. Broke up w/ Kelly by phone and went to bed shook up, then a tremendous thunder storm at 2200h - somethings such crashes that I imagined the canyon crumblng. I was in a rollaway bed by a picture window facing up canyon, and at fine the whole place was so brilliantly illuminated I could see distant geologic details. Heavy rain - 1.8" and 0.2" earlier in the afternoon.
