Genus Tamias - Chipmunks
There are 24 species in the genus Tamias. This genus represents the common and unmistakable chipmunks. Distinguishing species, however, can be an extremely difficult task in the field. The observer needs to examine a combination of field markings and the habitat and range of each species. Currently we have only profiled the colorado chipmunk, the eastern chipmunk and the least chipmunk in this genus.
In general chipmunks are distinguished from ground squirrels because of the stripes on their head. Often they are black, white and orangish in color.
Chipmunks have cheek pouches in which they can carry food to store in their burrows. Most burrow independently rather than in groups like ground squirrels. They can be seen in pairs only during mating season.
