Greene, H. 1990 August 8 Portal, Cochise Co., Arizona Arrived here approx 2100h, after flying from New Orleans to Tucson and driving here with Claudia Tuke. We just returned from the SSAR/HL meetings, Claudia having flown there, whereas I drove from Berkeley to Tucson last week. Driving down here we saw a fresh dead Crotalus scutulatus on Hwy 666 between I-10 and Douglas, a live small adult C. atrox after dark on Hwy 80 between Douglas and Rodeo, and a live neonate C. atrox on the Portal road. August 9 Late morning I went up the road to Paradise to look for our two radio-telemetryed male C. molossus: #1 (149.612 Mhz) was first caught in the canyon bottom in 1988; #5 (148.545 Mhz) was found w/ a female at a Nestorina nest last year. I climbed almost to the mirrocks, never getting more than a weak signal from #1 and concluded he might be over the ridge. Followed #3's signal into a shallow arroyo system a few hundred meters west of the parking turnout where both had originally been found and north of the road but couldn't localize him - didn't have head plums w/ me. Went to the Portal Post Office to check on my New Mexico collecting permit, and as I came out the woman sorting the house next door (Mrs. Wasser) asked if anyone could help her w/ a rattler in her yard! Went over and hooked an adult F C. molossus out of her rock wall - it was approx 60cm above ground,
