Overview
The California Kingsnake is one of the most widespread and variable snake species in western North America, ranging from Oregon through California, Arizona, and into northern Mexico. It occupies an enormous range of habitats, from deserts to grasslands to woodlands.
This species is well known among naturalists for its striking banded patterns and its natural resistance to the venom of rattlesnakes, which it will readily prey upon.
How to identify it
- Glossy, smooth scales with a variable pattern of alternating black/brown and white/cream bands or, in some populations, longitudinal stripes
- Head only slightly distinct from the neck, with round pupils
- Stocky, muscular body typical of kingsnakes
- Some desert populations show a striped rather than banded pattern
- Distinguished from venomous coral snakes and mimics by band arrangement and lack of a triangular head

Occupies an exceptionally broad range of habitats including deserts, chaparral, grassland, woodland, farmland, and suburban areas across California, the southwestern US, and northern Mexico, from sea level to moderate elevations.

It is a powerful constrictor and opportunistic predator, feeding on rodents, birds, lizards, and other snakes, including rattlesnakes, to which it has notable resistance. It is oviparous, laying clutches of eggs in summer.
