Chipmunks (genus Tamias)

Chipmunks are small ground squirrels with prominent lateral stripes often extending from the nose to the base of the tail. Their diet is omnivorous, primarily nuts, acorns, seeds, mushrooms, fruits, berries and corn, along with insects, bird eggs, snails and small mammals like young mice.

Eastern Chipmunk (Tamias striatus)

Biology:

The Eastern Chipmunk has reddish-brown fur on its back and sides and white fur on its stomach. It has two white stripes bordered by black on its sides ending at the rump, and one black stripe on the center of its back. The Eastern Chipmunk also has light stripes above and below its eyes, less distinct than other chipmunk species.

This chipmunk can be found in southeastern Canada and most of the northeastern United States south to Mississippi and Virginia and west to North Dakota and Oklahoma. Its typical habitat is open deciduous forests and the edges of woodlands. It can also be found in bushy areas and in rocky areas like walls near houses and other buildings.

In winter, it stays in its den. The Eastern Chipmunk doesn't truly hibernate, but it does spend a lot of time sleeping. It may wake up every few weeks to eat the food it has stored.
