Greene, IA 1990 August 11 (continued) - She started at my feet, ran erratically, then squirted my hand and chest with blood four fins from the left eye as I handled her. Blood was ejected w/ a distinct jerk backward and to the side of the head, thus aiming the stream at my hand - what would have been the eyes and/or mouth of a more natural predator. We road hunted the massasauga site for two passes back and forth between Bucher Canyon Rd. and Bernard's - got an AOR Crotalus atrox at 2002 hr (♂, 936 + 87 mm, 630 g - after I palpated 88 g of partially digested mammal from his stomach) and a large C. scutulatus AOR ♂ at 2007 hr, 24.4 mi SW State Line Rd. Hardy's had arrived when we returned, and Dave had caught three small Crotalus atrox on Hwy 9, to be released after processing: 6.1 mi E 80 on Hwy 9, 2042 h, ♂ 460 + 29 mm, 56 g, 3 rattles segments including button; 8.4 mi E Hwy 80 on Hwy 9, 2052 hr, ♂ 614 + 48 mm, 143 g, 6 segments including button; and some data as previous snake which it (this ♀) was following, ♀, 7/7 + 45 g, 248/260 g, 9 segments (incomplete), disgorged rodent that had been eaten head-first (1.3? + ? g). August 12 Cool, overcast, periodic light showers. Ground and vegetation were wet and rich w/ smells as Dave Hardy and I hiked over the canyon slopes to find our two radiotagged Crotalus molossus.
