| Palmer’s chipmunks live in a "sky island"—mountains in southwestern Nevada surrounded by deserts the chipmunks cannot cross. They are common there, foraging where rocks or fallen logs provide cover. They usually nest on or near the ground, although some nests have been found in trees. Females have litters of three or four young in late spring or early summer. The neonates are pink and hairless except for tiny whiskers, but within two weeks their stripes can be seen, and when they are a month old they have a sleek, smooth coat of fur. By five weeks, they are venturing outside the nest, and at six week, they are eating solid food.
