California Ground Squirrel

California Ground Squirrels are common in most west-coast states of the United States and Baja California. Recently they have expanded into Washington and Nevada. Where no snow falls, these ground squirrels are active all year. In colder regions, they hibernate for several months. During hot summers, they may estivate. They become tame in parks, such as this squirrel in La Jolla, California, and learn to take food from picnickers. They are not universally loved, as they feed on ornamental plants and trees and their burrows cause damage to lawns and gardens. These burrows are often communal, although each squirrel has its own entrance (Wikipedia).

Rattlesnakes prey on California Ground Squirrels. Many adult squirrels have some degree of immunity to rattlesnake venom. Squirrels will often provoke rattlesnakes to rattle their tails, allowing the mammals to assess the size and temperament of the snakes. Others will rise their own body temperatures and wag their tails. This behavior may give the snake the impression that they are dealing with a larger mammal than a squirrel (Wikipedia).
