Eastern Chipmunk

Description:

Perhaps the most distinctive characteristic of all chipmunks is their pouched cheeks. The pouches are located in the sides of their mouths and are used to store food. When the pouches are full they can be as large as an entire chipmunk's head. Eastern chipmunks are larger than most chipmunks. They are reddish brown in color with 5 black stripes on their backs. These stripes are separated by brown, white, or grey fur stripes. They also have white and dark markings around their eyes. The stomach is usually a yellowish brown or white color. Their tails are reddish brown and furry, but not bushy like common squirrels. Like many rodents, Tamias striatus has 4 toes on the front feet and 5 toes on the rear feet.

Habitat:

Eastern 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.

Notes:

This Eastern Chipmunk is one of many that live in our yard. It is eating the bird food off a stump (the squirrels and chipmunks destroyed most of our birdfeeders, so now we just put the food on stumps).
