Brief SummaryRead full entry
DescriptionEastern chipmunks are found in forests, but also in suburban gardens and city parks, as long as there are rocks, stumps, or fallen logs to provide perching sites and cover for burrow entrances. They dig complex burrows with many entrances and chambers as well as short escape tunnels, and each chipmunk defends a small area around its burrow, threatening, chasing, and even fighting with a neighbor who invades the space. The chipmunks spend the winter underground, but venture to the surface occasionally on mild, sunny days. They enter torpor for a few days at a time, and then arouse to feed on stored nuts and seeds. Life expectancy in the wild is slightly more than a year.
