Sonoran Whipsnake (info below from Reptiles of AZ):
This very fast moving, alert, diurnal predator forges in the mid-morning sun, often hinting with its head elevated high off the ground.It is primarily a ground-dweller but it spends some time in trees and often flees into the high branches of trees when threatened. It occasionally sleeps in trees on warm, humid nights. It hibernates during the cold months of late fall and winter. When captured it does not hesitate to bite.
