Eastern chipmunk

Scientific Name

Tamias striatus


The eastern chipmunk is so-called due to its distribution across eastern parts of the United States of America. Like other chipmunks, it has distinctive stripes down its head and back. Eastern chipmunks have 5 dark stripes separated by 4 lighter, cream-coloured stripes.

Although chipmunks are very competent climbers, they spend most of their time on the ground and are also capable of excavating tunnels underground.

They are diurnal (active during the day) and spend much of their time foraging for food. Chipmunks have large food pouches in their cheeks which they use to store food.

Female chipmunks have a gestation period of about 31 days. They usually give birth to a litter of 3-5 young, which are born hairless and blind. Chipmunks grow to full size after only 3 months and, if they are born in the spring, can be ready to breed the same summer. However, most individuals do not breed until the following year.

In the wild, they usually live between 2-3 years, but have been known to live as long as 8 years in captivity. 


Chipmunks are omnivores. They mostly eat nuts, berries, acorns and insects.
