The California Ground Squirrel is a large, mottled-brown ground squirrel abundant in grasslands and open woodlands throughout California and extending into Oregon and Nevada. It is a colonial burrower that creates extensive burrow systems used by many other species, including burrowing owls and kit foxes. California ground squirrels have evolved a remarkable resistance to rattlesnake venom and actively confront rattlesnakes to protect their young.
