Tamias striatus doorsiensis

Tamias striatus doorsiensis is a subspecies of the eastern chipmunk that is only found in Door, Kewaunee, northeastern Brown, and possibly Manitowoc counties in northeastern Wisconsin. It was described by C. A. Long in 1971. Compared to the other subspecies of eastern chipmunk present in nearby in Michigan and Wisconsin, they have brighter patches behind their ears, grayer hair along their backs, and more white on their tails. It is smaller than T. s. griseus but larger than the least chipmunk (Neotamias minimus).
