Red-tailed chipmunks sandbathe to clean their fur, rolling and rubbing, sometimes half-buried in sand. They are rarely seen outside their burrows on cold winter days, but in the spring they are out and about, eating seedlings, leaves, and flowers on the forest floor and also foraging in trees. Young chipmunks leave the nest when they are 30-45 days old. The mother stays nearby and calls to them constantly while they are exploring. Individuals can live as long as 8 years in the wild, although most do not live that long.
