Greene, H. 1991 August 5 partly cloudy and warm, now it is hot! The snake is (continued) in shade under a 4m tall juniper, stretched upslope but w/ head drawn back into a tight S-coil beside the tree trunk. I sat 3 m away and leave at 1200h, and the snake's head has turned downslope. At 1239h as I drive up to the paved Cave Creek Rd. from the Hardys' dirt road, I catch an adult ♂ C. molossus (1135 + 80 mm, 1.12 kg) as it crawls slowly and straight into adjacent brush. Spent the afternoon processing snakes and visiting Wade Sherbrooke at the SWKS, who gave me 2 frozen Crotalus. At ~1800h Barry Tonberlin caught a small ♂ C. molossus (785 + 52 mm, 287g) in the yard of folks SW (up canyon) from the Hardys - thus the third today around their house. I drove after dark to Hwy 80 on Portal Rd. and back, saw only an ROR C. atrox. August 6 at 0809h I found Crotalus molossus ♂ #3 stretched at the top edge of embankment on N. side of Paradise Rd., in general area where he was on afternoon of the 4th - thus he has returned ~300m since yesterday. At 0824 he started crawling E. at ~2 m/minute w/ almost constant tongue flicking; at 0830h I lost him - I thought he was searching for a slope to cross down to the road. At 0845 h I relocated the snake ~3-4 m N. of the edge in open grass and acacia, crawling more slowly - ~5 m by 0850h.
