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 &
