Eastern chipmunk

The Chipmunk is mostly reddish-brown, with five lengthwise dark brown to blackish stripes running from shoulders to rump, each with white fur down the middle. The furry tail, which is longer than the body, appears somewhat flattened. Fur is white to buff underneath, and feet are tannish. Pouches in the cheeks are used to store food. Males molt in April-May and August-September, while females only molt in June. Summer coat is more colorful than in winter. (Information from Tennessee's Watchable Wildlife website)
