Green, lt. 1992 May 25 (Continued) Tunnel into which the snake tried to escape. At 1652h as we drove back up to turn north on Hwy 80 a large St Tenapere ornata was crossing the dirt road. @ 1730h we localized the signal of Crotalus atrox #1 to a large woodrat nest under a mesquite tree, where Barney also found it on the 23rd. May 24 Overcast this AM, sun finally peing through at midmorning. at 1019h I spotted Crotalus molossus #11 still under a rock next to the road. At 1029h C. molossus #9 is stretched out North from the same woodrat nest, in this posture: at 1039h, Crotalus molossus #3 is out on a ledge ~1m from the opening of his rock cave, eyes still very blue. at 1058h. C. molossus #9 is now stretched fully extended from the rat nest, and I watched him continuously from a distance of ~15m across a small gully, from 1059h - 116 h. He initially crawled very slowly, evidently mainly w/ rectilinear locomotion.. He paused, lowered snout out of side behind a fallen branch (~x2-3cm) in some green leafy vegetation, and I could seeotypical bilateral jaw movement, so assume he was drinking (we had a shower earlier in the AM). After raising his head, the snake turned slowly to the right so that now the tail and rattle trailed straight toward the nest, perhaps
