The diet of common Eastern chipmunks consists mainly of seeds, nuts, fruits, green vegetation, and fungi. Other food items are young snakes, insects, bird eggs, and dead animals. These rodents are very opportunistic in their diet and will also eat any available food sources given a chance.

Chipmunks use their teeth constantly for gnawing on hard substances like wood, nuts, and tree bark. Their teeth can grow up to 2 to 3 inches. Their front incisors are always growing, which means that they have to gnaw on something constantly to keep them at a normal length.

Chipmunks can eat seasonal fruits like blackberries, blueberries, raspberries, strawberries and grapes. When these foods become scarce during wintertime, chipmunks switch over to nuts and seeds for sustenance.

They store their food in burrows, mostly under roots, for protection against other animals trying to eat the same nuts and seeds as they do.
