Chipmunks seem to feel their emotions with their tails.
For instance, as they watch you, you'll notice their tails twitch with curiosity. Even when they run, you'll see their striped tails sticking straight in the air. The colors of a chipmunk's fur are determined by the climate. Chipmunks eat all kinds of seeds, berries, grasses and even an occasional flower. They spend much of their day storing food for the leaner winter months.
