California Kingsnake (Lampropeltis californiae)STATUS





Description: Wild California kingsnakes are typically encountered at a length of 2.5 to 3.5 feet, though they can grow larger; California kingsnakes on Islas Angel de la Guarda, Baja California, Mexico, have been documented growing to 78 inches. A wide range of color morphs exist in the wild; they are usually found with alternating dark and light bands ranging in color from black and white to brown and cream. Some populations may have longitudinal stripes instead of bands.


Habitat: This species lives in a wide variety of habitats, including woodland chaparral, grassland, deserts, marshes, and even suburban areas.


Range: The California kingsnake is widespread along the West Coast of North America to elevations of approximately 6,100 feet in the Tehachapi Mountains and to over 7,000 feet in the southeastern Sierra Nevada Mountains. These snakes live in Oregon, California, Nevada, Utah, Arizona, southwestern Colorado, northwestern New Mexico, and northwestern Mexico. In Arizona, they intergrade with the desert kingsnake (Lampropeltis splendida) and the Mexican black kingsnake (Lampropeltis getula nigrita).


Found in these States: AZ | CA | CO | NM | NV | OR | UT


Diet: California kingsnakes are opportunistic feeders and common food items include rodents, birds, other reptiles and amphibians. The "king" in their name refers to their propensity to hunt and eat other snakes, including venomous rattlesnakes; California kingsnakes are naturally resistant to the venom of rattlesnakes. California kingsnakes are non-venomous and kill prey by constriction; they are the strongest constrictors proportionate to body size of any snakes. This adaptation may have evolved in response to the kingsnake's preferred reptilian prey, which needs less oxygen to survive an attack by constriction than mammalian prey items.


Reproduction: The California kingsnake is an oviparous internal fertilization animal, meaning it lays eggs, as opposed to giving live birth like some other snakes. Courtship for this kingsnake begins in the spring usually sometime after their hibernation or first shedding and involves the males competing for available females. In order to assert dominance when fighting another male, the California Kingsnake will get onto the other male and proceed biting the other snake. Their mating ritual begins by the male snake vibrating uncontrollably. Eggs are laid between May and August, which is generally 42 to 63 days after mating; in preparation the female will have chosen a suitable location. The typical clutch size is five to 12 eggs with an average of nine, though clutches of 20 or more eggs are known. The hatchlings usually emerge another 40–65 days later and are approximately eight to 13 inches in length. Adult California kingsnakes are most commonly 2.5 to 3.5 feet in length, and rarely exceed four feet.


Status: Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
