4. California Ground Squirrel Whoa, super cute!!! As is typical for ground squirrels, California Ground Squirrels live in burrows which they excavate themselves. Some burrows are occupied communally. Although they readily become tame in areas used by humans, and quickly learn to take food left or offered by picnickers, they spend most of their time within 25 m of their burrow, and rarely go further than 50 m from it. California Ground Squirrels are frequently preyed on by rattlesnakes. They are also preyed on by eagles, raccoons, foxes, badgers, and weasels. Interdisciplinary research at the University of California, Davis since the 1970s has shown that the squirrels use a variety of techniques to reduce rattlesnake predation. Some populations of California Ground Squirrels have varying levels of immunity to rattlesnake venom as adults. Female squirrels with pups also chew on the skins shed by rattlesnakes and then lick themselves and their pups (who are never immune to venom before one month of age) to disguise their scent. Sand-kicking and other forms of harassment provoke the snake to rattle its tail, which allows a squirrel to assess the size and friskiness (dependent on blood temperature) of the snake.[citation needed]rattlesnakesUniversity of California, Davisvenomcitation needed Another strategy is for a squirrel to super-heat and swish around its tail.[2] When hunting, rattlesnakes primarily rely on their pit organ, which detects infra- red. The hot-tail-swishing appears to convey the message "I am not a threat, but I am too big and swift-moving for it to be worth trying to hunt me." These two confrontational techniques also distract the snake from any nearby squirrel burrows containing pups.[2]infra- red
