From this site:
This fast moving and alert snake forges on the surface during the day. It often hunts with its head elevated high off the ground. [Anne says: See this post.] It is often active in hot conditions when other snakes seek shelter in cool retreats. Encounters with this snake are usually brief as it wastes little time disappearing into nearby cover when threatened. It spends most of its time on the ground but it is a capable climber that is occasionally encountered in trees and on cacti. It hibernates during the cold months of late fall and winter. When captured it does not hesitate to bite. If persistently harassed it may feign death by tucking the head down close to the ground and remaining motionless.
