Mammals; Mammals; Birds. 136 Field Museum or Natural History — Zoology, Vol. XI. specimens: Total length, 208 to 230; tail vertebras, 84 to 96; hind foot, 31 to 32 mm. The Little Chipmunk is common in northern and central Wisconsin at least as far south as Juneau County,* but does not occur in southern Wisconsin or Illinois. It is easily distinguished from the larger Chip- munk by its small size and narrower and more conspicuous stripes. Its most common note is a sharp "chip," somewhat resembling that of the larger species, but higher in pitch and more shrill. When fright- ened it often utters a shrill whistle. Its habits appear to be much the same as those of its larger relative, Tamias striatus griseus. There is no doubt that this species hibernates in winter but it does not retire to its winter home until quite late in the season, and its sleep is not so prolonged as that of some of its relatives. Mr. Ernest T. Seton writes, "In August and September the little Chipmunk emulates its cousin in labouring for the rainy days to come. As late as September 26 at Fort Resolution I saw one carrying home great bulging pouchfuls of skunk-grass seeds. About the end of the month, it finally plugs its doorway against the cold, the wet and the Least Weasel, and curls up for its six months' ; (1. c, p. 371.) Mr. Gerrit S. Miller found this species very abundant on the north.
