The proper scientific term for a chipmunk hole is a burrow. The two types of burrows that chipmunks construct are shallow burrows used for short-term refuge and deep burrows that are used for long-term living.
Deep burrows are more sophisticated than shallow burrows and can become very complex, consisting of many chambers. These types of burrows are where chipmunk colonies live, store food and hibernate during the cold seasons. Female chipmunks also give birth to their young within the burrow system, which provides protection from natural predators such as owls and hawks. Chipmunks tend to stay close to their burrows throughout their lifetime and rarely venture further than a few hundred feet from the burrow entrance.
