Greene, H. 1991 Journal March 25 Tucson, Pima Co., Arizona arrived here yesterday afternoon, left Berkeley morning before. Spent this morning examining Sistrurus catenatus in the University of Arizona collection, courtesy of Charles H. Jane and George Bradley. George, the technician, grew up around Prescott and told me he had seen a denning aggregation of Crotalus molossus near there. Also said he's seen woodrats in the stomachs of DOR Blacktail, and once an Ammospermophilus harrisii. Spoke briefly w/ Cecil Schwatke, who told me that April 10, 1986, he found a "court" pair of blacktails -- he will get details. Dinner w/ Katrina Mangin. March 26 Portal, Cochise Co., Arizona arrived here approx 1700h just ahead of a cold front. Snow down to approx 6-7000' el. in the Chiricahuas proper, but more on Finestone Mountain (our Crotalus molossus site) or other nearby outliers. March 27 From approx 1030-1230h I worked over the slopes of Finestone Mountain, our Crotalus molossus study site. Snow vegetation is bare and sparse, but if anything the catclaw spines are sharper than I've ever seen them. At approx 1130h, bright sun & clear sky, I traced the signal of M #7 (48.239) to a hole w/in a cave of a limestone outcrop, where Barney tells me the snake has been for some time. It is at the top of a fissure from which runs a mire of Nectoma droppings. I stuck my head up in the hole and heard a growling humming noise, then looked up to see bees flying!
