Greene, H. 1990 September 29 (continued) into a hole in under the boulder, never rattling. at 1610hr ♀ #5 was as earlier. At 1630hr we found ♂#1 as yesterday; in a putative hunting coil ~2m from a Nedora nest in an Opuntia clump. The rattler is in a flat, tight coil, tail invisible, head and neck in a level S-coil w/snout out over outer coil. Its snout points at the base of a shrub ~15cm away, and I think a runway passes to the visible nest entrance between the snake and the shrub-base. At 1652hr Dare spotted an adult Salvadora grahamiae frozen beside a dead upright sotol (?); as I approached it dashed around the plant and froze, where I got it w/ a clamp stick. At 1658hr I spotted a Syringas. At 1626hr we had found ♂#3 w/head just out from under a boulder, 26m uphill from where Dare spotted him crawling. We also found ♂#7 coiled under a bush--details on all sightings are on separate data sheets. After dinner I talked to Diane Wagner at SWKS, former VCB student and now working on a Ph.D. at U of T. She saw a Sistrurus catenatus 200m W of Peach Orchard Rd, 0.5mi N. of Portal Rd., 3.3 mi E. of Portal, in acacia scrub w/ some grass. The snake was flattened on the ground at dusk, and crawled into a bush when disturbed. September 30 Rain began ~0500hr and continued as a steady
