5. What do chipmunks eat and how do they behave?

Eastern Chipmunks are omnivores. They eat nuts, seeds, berries, insects, and bird eggs. They stuff their cheek pouches with food and carry it to their burrows. They are territorial and will chirp or flick their tails when alarmed. Watch for them darting across paths or climbing low shrubs.

The easiest way is to look for facial stripes. Chipmunks have a light stripe above and below each eye, unlike ground squirrels. The Thirteen-lined Ground Squirrel has more stripes and spots, and lacks cheek pouches. Chipmunks also have a more upright posture when feeding. Check ourchipmunk identification guidefor more details.
