attacks. This successful dodging, along with the fact that the adult squirrels are larger than the young ones, helps to deter the predators, as the rattlesnakes are 1.6 times more likely to be deterred from attacking an area after an encounter with an adult squirrel. In 30 out of 45 interactions with snakes, the tail-waving behavior of the squirrels stopped the snake in its tracks and the snake attempted to wait for the squirrel to leave before it would consider attacking again, showing that the behavior does deter predatory attacks by the rattlesnakes. This is due to the adult squirrels being vigilant and looking more threatening and also that they are able to more successfully dodge attacks. They also can use their tail-waving to signal to other ground squirrels in the area that a rattlesnake or other predator has recently been spotted. Though the ground squirrels have been found to also exhibit this tail-waving behavior when no predator is present, they wave their tails faster and for a longer time when they spot a predator or in an area where a predator has recently been spotted.

aware that they are in an area where the rattlesnakes have recently been, they devote more time to being alert and searching for the predators than to hunting and foraging than in an environment where they do not believe predators exist. These vigilant squirrels were found to have a faster reaction time to a stimulus from a predator and jump higher and further away than a squirrel that was not as vigilant. In a simulated environment study, 60% of squirrels that were in an environment with a recent snake encounter exhibited an evasive leap behavior, which propels them farther away from their attackers; 20% of squirrels exhibited this behavior in a primary encounter with a snake and roughly 5% of squirrels exhibited this behavior when no snake was present and no threat was detected. This shows that the squirrels are more alert, vigilant, and ready for an attacker after one has been recently seen.

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 (80 ft) of their burrows, and rarely go further than 50 m (160 ft) from it. 1075: 412:
California ground squirrels' mating season is early spring and tends to last only for a few weeks. The females are considered to be promiscuous, so the individuals of one litter can be from multiple mates. The California ground squirrel has one litter of five to eleven per year, with gestation around

Vigilant behavior in squirrels is also a defense mechanism to avoid predation. In addition to the tail-waving, the squirrels have been found to be more vigilant and on alert if a predator had recently been in the area than they were if no predator had been detected. If the ground squirrels are

The swishing of the tail from side to side is called tail-waving, which helps the squirrel to deter a snake attack. The snakes attacked the squirrels that exhibited the tail-waving at a shorter distance than those that did not and majority of those tail-waving squirrels successfully dodged these

as adults. Female squirrels with pups also chew on the skins shed by rattlesnakes and then lick themselves and their pups (that are never resistant to venom before one month of age) to disguise their scent.

The coloration of the young is slightly lighter than the adults, and molting occurs at about eight weeks of age – when the young leave the burrows. California ground squirrels can live up to six years.
