Conservation
IUCN Red List status is Least Concern, as the species is widespread, adaptable, and generally maintains stable populations despite habitat fragmentation and road mortality.
Physical Description
Displays high-contrast alternating bands of dark brown/black and yellowish-white or cream. The head is slightly distinct from the neck with light speckling or a pale snout pattern, round pupils, and smooth, glossy scales giving a polished appearance.
Size & Dimensions
The pictured specimen appears to be a subadult or small adult, roughly 2 to 2.5 feet long. Adults typically range from 2.5 to 4 feet (76 to 122 cm), with exceptional individuals reaching up to 5 feet.
Habitat
Extremely adaptable, inhabiting areas from sea level up to around 7,000 feet. Found in chaparral, grassland, oak woodland, desert, scrubland, agricultural areas, and suburban peripheries, often near water sources or rocky outcrops.
Diet & Feeding
Generalist predator feeding on rodents, lizards, birds, eggs, and other snakes (including reptiles immune to various venoms). Utilizes active foraging and constriction to subdue prey.
Reproduction
Oviparous, typically mating in spring (April to June) and laying clutches of 5 to 12 (sometimes up to 20) eggs in subterranean chambers or under debris during early summer, with incubation lasting around 60 days.
Look-alikes
Often confused with other kingsnake species or venomous elapids such as coral snakes (though geographic ranges differ, and the coloration rule differs—black touching yellow/white in kingsnakes versus red touching yellow in North American coral snakes).
Conservation Status
IUCN Red List status is Least Concern, as the species is widespread, adaptable, and generally maintains stable populations despite habitat fragmentation and road mortality.
Cultural Significance
Frequently kept in captivity due to hardiness and docile temperament; plays an important ecological role in controlling rodent and reptile populations.
Notable Features
Renowned for robust immunity to the venom of local snakes such as rattlesnakes, frequently incorporating other snakes into its diet.
