It eats acorns, hickory nuts, pecans, berries, seeds, and insects such as grasshoppers, beetles, katydids, and cicadas. Size. Least chipmunks benefit from the larger caches of eastern chipmunks, which store up to four times as many seeds. Stripes on the face distinguish this species from all other mammals over most of its range. Accessed The eastern chipmunk is found abundantly throughout the middle and eastern sections of the United States. Most chipmunks that were recaptured in the second and fifth years occupied their original home ranges. Journal of Mammalogy, May 2002, Vol. Their tail is hairy, but not bushy and is somewhat flattened. Disclaimer: New York: Adirondack Wildlife Program, State University of New York, College of Environmental Science and Forestry, 1988. (Da Silva, et al., 2002; Kurta, 1995; Saunders, 1988), Eastern chipmunks produce two litters per year; one in early spring and one in midsummer.

There exist several published accounts of swimming chipmunks (e.g., Wilber and Weidenbacher 1961; Dagg and Wilson 1972), but each of these studies consists of researchers dropping mammals into a pool of water to ascertain whether and how well they swim. Females do not disperse as far as males and have more relatives living close to their burrows. However, least chipmunks' stripes extend to the base of their tail, whereas, eastern chipmunks' stripes stop before their rump patch. The eastern chipmunk is large (up to 125 g) with a relatively short tail (about one-third of the total length from its nose to the tip of its tail), whereas western chipmunks are smaller (about 55 g) with a relatively longer tail (nearly half the total length from its nose to the tip of its tail). Family: Sciuridae. Behavior . Abstract: We were interested in what influences home ranges of eastern chipmunks (Tamias striatus).
