Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at a 'very high' or 'extreme' level.

Chipmunk

Tamias striatus
Eastern Chipmunk

Description: The eastern chipmunk is the only chipmunk found in Connecticut. It is reddish brown in color with a single black stripe running down the center of its back. A white stripe between two black stripes runs down each side of its body from the neck to the base of the tail. The chipmunk has a white underside and a white stripe above and below its eyes. Chipmunks range in size from 8 to 10 inches long (including the tail) and weigh between 2 to 5 ounces. There is no difference in appearance between males and females.

Range: The eastern chipmunk is found throughout the eastern United States, west to the Mississippi River and in southeastern Canada.

Habitat and Diet: The eastern chipmunk is found in deciduous forests, shrub habitat, forest edges, and suburban and urban areas where there is abundant cover to protect it from predators.

Chipmunks are omnivores (they feed on both plants and animals).  Their diet includes seeds, nuts, berries, fruits, flowers, mushrooms, insects, worms, snails, frogs, bird eggs, and small birds.

Life History: Chipmunks mate twice a year from February to April and again from June to August. Males and females come together only to mate. Females raise their young alone.  After a gestation period of 31 days, a litter of 2 to 6 young is born (some litters may be as large as 9 young). Hairless, blind, and helpless, newborn chipmunks are about the size of a bumblebee. The young remain underground in the burrow for about 6 weeks. After approximately 8 to 10 weeks, they are fully independent and leave the female. Chipmunks reach sexual maturity in about 1 year.

Interesting Facts: Chipmunks are an important food source for a number of predators including hawks, snakes, weasels, foxes, bobcats, raccoons, rats, owls, and coyotes. House cats also prey on chipmunks.

When chipmunks feed on plants and fungi, they help disperse the seeds of these organisms. Burrowing by chipmunks also may help aerate and recycle soil.

Chipmunks are most active in the early morning and late afternoon. Although they can climb trees, they spend most of their lives on the ground or underground in burrows that may reach 30 feet long and 3 feet deep. These burrow systems include nesting chambers and storage rooms for nuts and seeds that provide chipmunks with food throughout the winter. The burrow entrance usually measures two inches in diameter. Chipmunks remove the fresh dirt from the opening to avoid being conspicuous to predators. They fiercely guard their territory from other chipmunks.

Beginning in late October, chipmunks sleep for long periods throughout the winter but they do not hibernate. They occasionally wake to snack on stored nuts and seeds and may even come outside for brief periods of time on warm winter days.

Chipmunks are very vocal and make a variety of noises. They get their name from the "chip, chip" sound they make.

An enormous amount of food can be held in their cheek pouches, which can stretch to three times the size of the head. When gathering large nuts, chipmunks bite off sharp edges and stems.

Chipmunks have 4 toes on their front feet and 5 toes on their back feet.

Management of Nuisances: Although chipmunks do not cause serious agricultural damage, they can be a nuisance in the garden where they eat flower bulbs, fruits, seeds, and seedlings. They also may cause structural damage by digging under patios, porch stairs, walls, or foundations.

Exclusion, landscape modifications, repellents, and trapping are all means for dealing with nuisance chipmunks. To exclude chipmunks, use 1/4-inch mesh hardware cloth to keep chipmunks away from gardens and flower beds.

To discourage chipmunks from burrowing around the house foundation, ground covers, trees, and shrubs should not be planted in a continuous fashion connecting wooded areas with the foundation of the house, and avoid locating wood piles or debris near the house. Chipmunks are attracted to bird feeders where they gather spilled seed. Position bird feeders at least 15-30 feet away from buildings.

Repellents, such as taste repellents, may discourage chipmunks, but this technique usually requires multiple applications and repellents should not be used on any plants intended for human consumption.

Trapping is the most practical method of eliminating chipmunks in most home situations. A variety of baits can be used, including peanut butter, nut meats, pumpkin or sunflower seeds, raisins, prune slices, or common breakfast cereal grains.
