After a 30-day gestation, a litter of two to eight is born.

All ground squirrels are solitary; however, since chipmunks are not very territorial, many may be seen in close proximity, particularly if there is a good supply of food at that location.

The Uinta chipmunk ( T. umbrinus ), which lives in montane forests of the western United States, is much like a tree squirrel in its habits. Swept up in a holiday mood, Alvin gives away his cherished harmonica to a sick little boy.

Chipmunks are social animals, and both the male and female raise their young. The chipmunk is a member of the rodent family who can live to be 8 years of age, though average lifespan is between two and three years.

Chipmunks are diurnal, meaning that they are active during the day. Chipmunks feel most at home in areas with plenty of ground cover, including logs, trees, stumps, shrubs and rocks. This interaction between chipmunks and humans has lead to many depictions of these cute animals, but when real-life chipmunks and people meet, problems can occur. During this time, an adult female typically produces between 20 and 30 offspring, depending on how abundant food supplies are. In species such as the eastern chipmunk, females provide all of the care to their litters. While other mammals experience one breeding season per year, chipmunks have two.

The pups begin to grow fur during the second week of life and start to develop signature markings by the third and fourth weeks.

While the ideal habitat for chipmunks is a deciduous forest, woodland or brushland, they’re also comfortable in other areas that provide sufficient cover such as …

The babies are born and reared in an underground burrow and are tended to by their mother. If they make their way inside, and you cannot handle the problem after using the above methods, call an exterminator as soon as possible.

There are 25 chipmunk species.

Newborn chipmunks are born hairless and don't open their eyes for the first month of life. Chipmunks are solitary creatures and normally ignore one another except during the spring, when mating takes place. Chipmunks are members of the squirrel family of mammals. Similar to squirrels, they may also be carriers of rodent-borne illnesses and rabies. Chipmunks have a life span of 2 – 7 years in the wild. Chipmunks potentially carry fleas, which in turn transmit viruses like Lyme’s disease. During those times, the females will attract males with a shrill, birdlike chirp as an invitation. Baby chipmunks are born blind and without fur, measuring a scant 2 or 3 inches. In addition to denning in burrows, it regularly sleeps and nests in trees, where it sometimes raises young in tree cavities or abandoned bird nests.

A chipmunk’s life is mostly solitary – until breeding season. Meanwhile, Dave has booked Alvin to perform a harmonica solo at Carnegie Hall!
