Greene, H. 1992 May 20 (continued) for lunch and walked over the slide - at 12:15 hrs Bill found an adult C. piecei w/ opaque eyes tucked under a rock in sun and rattling, in a small patch of shrubs high on the slide. After stopping by the house, Dave and I checked our radiotagged blacktails. At 14:15 hr we spotted C. molossus #9 in a resting coil (flat, head down in it filled up) in dappled sun at the base of the woodrat nest. At 14:30 hrs we found C. molossus #3 in a tight resting coil at the same rock hole entrance, facing out w/ milky sapphires obvious blue eyes and still old skin, some sun hitting him. His 13 month old sutures are still visible. At 14:50 hr we encountered a small adult ?(?) crossing the road to the south <0.1 mi NW of the Forest Service cattle guard on our study site. Snake was frozen extended in sun when spotted. As we took photos, it crooked the neck in our direction & tongue-flicked. When grasped w/ a clamp stick it struck a short flashing jab at me - couldn't see if fangs were erect. At 15:20 hrs we located C. atrox ? #1 ~300 m NNW of release site ~200 m W. of the Gee's house. Snake was crawling slowly in straight line in shade of a large brush, but coiled and rattled as we approached to 2 m - it rattled continuously while we took notes etc. An impressive contrast w/ C. molossus.
