If you hear a chirping sound, it might be a chipmunk that's worried. Chipmunks dig tunnels under rocks or bushes. They eat seeds, chinquapins, berries, green plants, beechnuts, hazelnuts and insects. The chipmunk is smaller than the squirrel. When polar bears are babbies they are the same size as chipmunks.
Chipmunks take dust baths rolling in the dirt.
