Grease, H. 1992 August 23 yesterday, crawlig slowly, during head side to side, (continued) tongue flicking, in low brush on the low plateau. At 1150h we found C. molossus ♀ #17 in a tight hair spin coil against the rock wall base in grass at the same site as yesterday. At 1217h C. molossus ♀ #17 is ≤ 50m N of former site, out of sight in a hole. At this point, viewing our study site, the main plants are juniper, sotol, agave, sunac, acacia, ocotillo, and prickly pear. Next came a frustrating but ultimately successful search, because we were rapidly running out of receiver power- signal going up and down in volume, losing then gaining directionality. At 1248h we found C. molossus ♂ #13 & ♀ #15 together to 30-50m NE of yesterday's site, in a loose coil w/♂ over ♀, tails not joined. We alternated bouts of Forward Jerks and Tail Searches w/ quiet, captured on video by Dave. At 1258h she whipped her tail so strongly that I could hear her rattles against vegetation from 4m away. They paused, he resumes FJ's at 130/h. afternoon spent packing, then dinner at the store w/ Sarah, Hardys, Barney, & Tony. August 24 left Portal, lunch w/ herp crew from Desert Museum in Tucson, then a 2-hour visit w/ Beth Gibson in Sedona. Drove to Kizmar tonight in a motel, to Berkeley manara.
