Overview
The Sonoran Mountain Kingsnake inhabits rocky, montane habitats across Arizona, parts of Utah, New Mexico, and northern Mexico. Its bold banding is a textbook example of Batesian mimicry, resembling the pattern of the Arizona coral snake found in overlapping range.
Despite its coral snake-like colors, it preys on small vertebrates.
How to identify it
- Bands of red, black, and white/cream encircling the body
- Black bands typically bordering red
- Smooth, glossy scales
- Rounded head, not triangular
- Distinguished from Arizona coral snakes by band sequence and larger, more robust body
