Both species showed signs of being very selective in choosing cache locations to prevent their caches from being robbed. It is mainly active during the day, spending most of its day foraging. Alarm calls can be costly and the benefits must outweigh the costs to justify such behavior. It prefers bulbs, seeds, fruits, nuts, green plants, mushrooms, insects, worms, and bird eggs. When they are about a year old, they reach sexual maturity and begin reproducing themselves. Eastern chipmunks are not noted for causing this type of damage. Kroll, M. 2013. Eastern chipmunks demonstrate food caching behavior throughout the year, but are particularly active in the early autumn to prepare for winter. Typically females in estrous stay within their home range and males come from outside areas to mate. Juvenile females trill at a lower rate than adults, this may indicate their higher predation risk or smaller fitness gain. Because of their abundance, chipmunks are a valuable prey item for a variety of species. Females stay close to their home burrow with their range sometimes overlapping. The Animal Diversity Web is an educational resource written largely by and for college students. (Kurta, 1995; Saunders, 1988), Some Sciurids cause destruction to crops in gardens, fields and in food storage areas. Theyr eyes don't open until they are about 28 days old, and their hair is grown in completely by the time they are 40 days old. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe.

Most litters contain between three and five young. Chipmunk Reproduction Chipmunk breeding season occurs in early spring and then again in early summer. The Animal Diversity Web team is excited to announce ADW Pocket Guides! Eastern chipmunks in Wisconsin mate only in the summer due to the cold weather March. It lives in a great variety of human generated ecosystems including fence rows, city parks, gardens, cemeteries, and even college campuses. - NatureWorks Their burrow is excavated less than one meter below the surface and has interconnected galleries up to 10 meters in length. (Kurta, 1995), Eastern chipmunks are diurnal and most active during mid-morning and mid-afternoon.  It is only found in Door, Kewaunee, northeastern Brown, and possibly Manitowoc counties in northeastern Wisconsin. Chipmunks remain in their deep burrow systems during the winter, where they enter patterns of torpor (deep sleep and lower body temperature) interrupted by periods of feeding. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico. New York: Adirondack Wildlife Program, State University of New York, College of Environmental Science and Forestry, 1988. Reproduction cycle Send us your chipmunk drawings! While foraging, chipmunks often stuff food in their cheeks which can expand up to 3 times their normal size. Age, available food, and the duration of snow cover are some factors influencing litter frequency. Trill vocalizations are complicated and more difficult to understand than the other two types of calls. Individuals that do not disperse have home range lengths of up to 0.5 km throughout their lifetime. An animal that eats mainly plants or parts of plants. n. from the eastern chipmunk, Tamias striatus. Ann Arbor, MI: University of Michigan Press. The gestation period lasts about a month. The eastern chipmunk lives in deciduous wooded areas and urban parks throughout the eastern United States and southern Canada. The neonates are weaned 40 days after birth. living in the Nearctic biogeographic province, the northern part of the New World. (Smith, 2005). There are three genera in this family: Tamias (eastern North America), Neotamias (western North America) and Eutamias (Eurasia). ... lead to less breeding and the failure of the second litter. This cue is dependent on the substrate and the moisture content of the seeds. (Da Silva, et al., 2002; Kurta, 1995; Saunders, 1988) Mating System; polygynous 2: 546-552. Tamias striatus. On average, males travel 170 meters from their burrow to mate. Their range includes eastern Louisiana and the Florida Panhandle. Different chipmunks hibernate more or less than others, with some becoming completely dormant in winter, some being active during mild periods, and others being active all winter. During the winter, the chipmunk may enter long periods of torpor, but does not truly hibernate. Caches are marked with an olfactory cue to aid in relocation. Description: The Chipmunk is mostly reddish-brown, with five lengthwise dark brown to blackish stripes running from shoulders to rump, each with white fur … Diet: Chipmunks eat mainly seeds and nuts, but also consume mushrooms, fruits, berries, corn, small invertebrates, bird eggs, and sometimes small vertebrates. Chipmunks are small rodents of the squirrel family with a total of 25 different species (see bottom of page), all part of the scientific family, in the family Sciuridae. Eastern chipmunks spend more time digging and searching for caches because least chipmunks hide seeds away from objects, which could be used as markers. They are also easily tamed and can make unique pets. Least chipmunks benefit from the larger caches of eastern chipmunks, which store up to four times as many seeds. "Small Mammals and Agriculture: A Study of Effects and Responses" (On-line). This species does not occupy the peninsula of Florida or the coastal plains region, from Florida to North Carolina. Journal of Mammalogy, May 2002, Vol. Help us improve the site by taking our survey. However, cache defending behaviors were deterred in this study. Eastern chipmunks eat insects and may be helpful in controlling the population of some pest species. Adironack Animals. It has a tawny stripe that runs from its whiskers to below its ears, and light stripes over its eyes. They typically have only one litter of up to seven young, which are born in May or June. They also are important to spore dispersal for different kinds of fungi. Lifespan of this rodent in the wild is only 2-3 years. It is the only living member of the chipmunk subgenus Tamias, sometimes recognized as a separate genus. The range of a chipmunk is approximately two acres in size and shared with other chipmunks, but they are careful to defend their burrows for fear of having their food caches stolen. Both species breed in April and give birth about a month later. (Da Silva, et al., 2002; Kurta, 1995; Saunders, 1988), Eastern chipmunks produce two litters per year; one in early spring and one in midsummer. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. It also lines the burrow with leaves, rocks, sticks, and other material, making it even harder to see. Eastern chipmunks are found throughout eastern Canada and eastern United States. It has several bird-like or chattering calls; one is a trill at the rate of 130 vibrations per minute and another is a lower-pitched, clicking sound. Eastern chipmunks are polygamous. , Eastern chipmunks are known to be one of many hosts for the parasitic larvae of Cuterebra botflies. Some dispersal, up to 0.9 km, will occur.  The name "chipmunk" comes from the Ojibwe word ajidamoo (or possibly ajidamoonh, the same word in the Ottawa dialect of Ojibwe), which translates literally as "one who descends trees headlong. The eastern chipmunk is found abundantly throughout the middle and eastern sections of the United States. However, their occasional scatter-hoarding behavior can be beneficial in seedling establishment. A common and abundant species across its range, this diurnal squirrel is very clever at avoiding detection when needs be. To do this, she will dig new entrances into her burrow although never using them. Young become independent two months after birth. Sniffing hindquarters and touching noses provides chemical signals during these interactions. Their tails can grow as long as 3 to 5 inches (8 to 13 cm). Smith, J.
