Chipmunks are small, striped rodents of the family Sciuridae. All species of chipmunks are found in North America, with the exception of the Siberian chipmunk, which is found in Asia.
Chipmunks have an omnivorous diet primarily consisting of seeds, nuts and other fruits, and buds. They also commonly eat grass, shoots, and many other forms of plant matter, as well as fungi, insects and other arthropods, small frogs, worms, and bird eggs.
The eastern chipmunk hibernates in the winter, while western chipmunks do not, relying on the stores in their burrows. Eastern chipmunks mate in early spring and again in early summer, producing litters of four or five young twice each year. Western chipmunks breed only once a year. The young emerge from the burrow after about six weeks and strike out on their own within the next two weeks.
Chipmunks typically live about three years, although have been observed living to nine years in captivity.
