Greene, H. 1985 5 August (continued) freshly ingested leptotyphlops (4g). Barney and Max had gone to New Mexico, where they collected a Gylpius canum and a Crotalus that appears scale-wise and in coloration to be a hybrid Crotalus molossus x scutulatus. They also gave me a DOR adult C. scutulatus from New Mexico and a just hatched C. molossus from Cave Creek Canyon. What a day! [Need to add some mammal notes: yesterday I saw an Apache Fox Squirrel on the road to Ash Spring and Ursus americanus scat on the trail above there. I have seen numerous deer, rabbits, and ground squirrels. Just dusk, at 1759 hr, I encountered a javelina just down the paved road to Portal from Dave Hardy's house] I must stress how impossible it was to tell head from tail on the Micrurusoides during its display. 6 August Drove up to the collection site of Elaphe lisaapis for photographs -- heavily wooded on the SW, w/ canyon walls nearby, open field w/oaks, then stream and canyon walls on the NE. Back to Barney's for breakfast and photographs of the snakes. The Micrurusoides repeated its performance, and I noticed that when the body extends and freezes, the head is tucked back acutely, enhancing resemblance to the tail. As I drove S. of Portal @ 0930 hr, found a ~5' Pituophis melandricus stretched out on the pavement.
