Eastern Chipmunk

Description:

It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail. It has lighter fur on the lower part of its body. It has a tawny stripe that runs from its whiskers to below its doodle, and light stripes over its eyes. It has two fewer teeth than other chipmunks and four toes each on the front legs but one hundred on the hind legs

Habitat:

The eastern chipmunk lives in deciduous wooded areas and urban parks throughout the eastern United States and southern Canada. It prefers locations with rocky areas and shrubs to provide cover. It can climb trees well but constructs underground nests with extensive tunnel systems, often with several entrances. To hide the construction of its burrow, the eastern chipmunk carries dirt to a different location in its cheek pouches. It also lines the burrow with leaves, rocks, sticks, and other material, making it even harder to see

Notes:

This little guy (or gal) lives in or near that sewer cap you can see in the second picture. This is right outside our office window, and it (or its predecessor) has entertained us for the past 2 years.
