Greene, H. 1993 July 29 (continued) released C. willardi ♀ #18 at her exact capture site and she coiled under the rock facing out. At 0855 I checked the spot where C. willardi ♂ #16 & ♀ #17 were and could see coils of two snakes and a relatively large head looking out. At 0857h C. willardi ♀ #14 glides in the grass w/out rattling from a grass clump ~50m from her hole under the rock and disappears into it. At 0907h I spotted immature C. willardi ♂ #8 ~5m below his last site - at base of the rockslide in sun-shade mosaic. I actually heard him in the grass then saw him glide w/out rattling, continued slow crawl w/tongue flicks and a few ant-post head jerks. Photographed his pattern, including yellow paint dot on head & rattle. He has a recent & fairly large food belly. At 0920h I failed to spot C. willardi ♀ #15 at either of the crevices where she was earlier telemetrically located (I don't have the equipment w/me now). Next spent ~30 minutes in Scotia Canyon, walked to the large rock piles, then back by way of wooded opposite side of creek. At 0940 a juvenile Crotalus lignatus rattled as it escaped into oak leaves at the base of a tree - heard then saw it. There were many dead Vardus nearby, in shade. Driving south do so over Montezuma Pass &
