The chipmunk's preferred habitat is the edge of woodlands. He enjoys running about on old stone walls and perching on woodpiles. He will often site its burrow near a rock pile, or an old tree or stump. The entrance to the burrow is a round hole about two inches in diameter. The shaft plunges straight down about seven inches, then veers, sloping downward two or three feet, to various chambers.
Different chambers serve different purposes.
Some are for the storage of food, the deepest chamber is the toilet, and the largest chamber, toward the rear of the main shaft, is for the bedroom. This is an oval room, about one foot wide and one foot high. Here, the chipmunk makes a warm bed of shredded leaves and grasses. His bed lies directly on top of a large heap of nuts and seeds. The chipmunk moves the excavated soil several yards from the main entrance so as not to attract predators.
