A Madrean Mountain Kingsnake from the southeastern corner of the state. These colorful snakes can be surprisingly difficult to spot, despite their bright coloration.

A dull Arizona Ridgenosed Rattlesnake found out at night in madrean oak forest of southeastern Arizona. Nocturnal activity is common with this species during the humid, hot nights of monsoon season.
