The California kingsnake (Lampropeltis californiae) is a wide-foraging generalist predator which feeds on a variety of prey items including small mammals, lizards, birds, and even other snakes. Though this species is broadly, anecdotally known for preying on venomous rattlesnakes, recent studies highlight dietary composition reflective of seasonal and geographically available prey . In the photo, an adult kingsnake lifts its head to get a better view as it checks out its surroundings.
