“The eastern chipmunk (Tamias striatus) is a small, striped rodent found in North American woodlands. A member of the squirrel family, it is the only living member of the genus Tamias, one of three genera of chipmunks. Its distribution extends from southern Canada in the north to Louisiana and the Florida panhandle in the south, and from the middle United States in the west to Virginia and the western mountains of the Carolinas in the east.
The eastern chipmunk is solitary (except during its mating season), diurnal, and lives in a burrow of extensive tunnels, well-hidden entrances, and chambers for sleeping, nesting, and storing large quantities of food. In winter, the chipmunk retires to the burrow, enters a state of torpor, but wakens frequently to move about underground or to eat from its stores. It vocalizes with bird-like chirps, chips, chucks, and squeaks. Predators include hawks, foxes, and weasels.
The eastern chipmunk is omnivorous, and its diet includes nuts, seeds, and fruits as well as insects. The breeding season occurs annually in the middle spring, or biannually in early spring and again in middle summer, depending on the geographic region. Gestation is 30–32 days, and the young leave the nest at about seven weeks. The species is infected by internal and external parasites including a host-specific louse and a mite that damages the end of the tail. In the wild, lifespan is one to three years, and in captivity, about nine years." Wikipedia
