Greene, H. 1989 June 2 (continued) modestum sun at our feet in open scrub, The animal made several short runs (~1m), and each time upon stopping wagged its tail back and forth several (~3-6) times. The plane of movement was largely lateral but at times the distal ~1/4-1/2 was slightly deviated. Portal, Chiricahua Mtns., Cochise Co., Arizona as we pulled into the Hardy's driveway I saw an adult ♀ Pituophis melanolaeus slowly crawling in full sun at 1116 hrs. Only response to being picked up was attempt to crawl away. Freshly shed (bright colors and one small piece of old skin on her side), neither skinny nor fat. Palped a small rodent (saved) and released the snake. At 1644 hrs I found the melanoleucd Crotalus molossus deep in its crevice/hole, only a loop of its body visible by flashlight. From ~1900-2015 hrs Claudia and I repeatedly road hunted the first ~2 miles east of Portal, but saw no snakes. June 9 at 0805 hrs I saw an adult Pituophis melanolaeus escape into grass and mesquite ~1/2 mi W. Portal.
