The Animal Diversity Web is an educational resource written largely by and for college students. After breeding, the male returns home and takes no part in the care of the young. New York: Adirondack Wildlife Program, State University of New York, College of Environmental Science and Forestry, 1988. Eastern chipmunks are listed as a species of Least Concern according to the IUCN Red List. This cue is dependent on the substrate and the moisture content of the seeds. Accurate reproduction of the skull of Tamias striatus. Lifespan of this rodent in the wild is only 2-3 years. Their burrow is excavated less than one meter below the surface and has interconnected galleries up to 10 meters in length. Their rounded ears measure less than 20 mm. [11] 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. After one month, their eyes open and they have become completely covered with fur. It prefers locations with rocky areas, brush or log piles, and shrubs to provide cover. The ADW Team gratefully acknowledges their support. Their tails can grow as long as 3 to 5 inches (8 to 13 cm). Linzey, A. The Eastern Chipmunk (Tamias striatus) is a small, striped rodent found in mature hardwood and mixed wood forests in the Adirondack Mountains of upstate New York.Eastern Chipmunks (like American Beaver and North American Porcupine) are assigned to the rodent (Rodentia) order, the single largest group of mammals.The Eastern Chipmunk is a member of the squirrel family (Sciuridae). However, least chipmunks' stripes extend to the base of their tail, whereas, eastern chipmunks' stripes stop before their rump patch. 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. It also lines the burrow with leaves, rocks, sticks, and other material, making it even harder to see. They are hairless, and their eyes are closed. Their nest is made out of crushed leaves and measures 30 cm in diameter. Caches are marked with an olfactory cue to aid in relocation. Chipmunks typically grow to around 4 to 7 inches (10 to 18 cm) and weigh 1 to 5 ounces (28 to 142 g). Large raptors including red-tailed hawks and goshawks also prey on chipmunks. Their range includes eastern Louisiana and the Florida Panhandle. Females have two estrus cycles per year: one in March or early April, one in late July or early August. Vander Wall, S., S. Jenkins. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Their tail is hairy, but not bushy and is somewhat flattened. Alarm calls can be costly and the benefits must outweigh the costs to justify such behavior. (Vander Wall and Jenkins, 2011), Eastern chipmunks are not significantly important to the economy. 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. 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. It is mainly active during the day, spending most of its day foraging. To hide the construction of its burrow, the eastern chipmunk carries soil to a different location in its cheek pouches. Help us improve the site by taking our survey. Tamias striatus. A comparative study of caching and pilfering behavior in two sympatric species, least chipmunks (Tamias minimus) and eastern chipmunks (Tamias striatus). 83, No. During a brief estrous period, females mate with multiple males. 2005. (Kurta, 1995; Penner and Devenport, 2011), Eastern chipmunks are somewhat tolerant of humans and will sometimes burrow under buildings. Breeding males have the largest home range. Females stay close to their home burrow with their range sometimes overlapping. Kroll, M. 2013. (Baack and Switzer, 2000; Da Silva, et al., 2002; Saunders, 1988), Dietary staples include fruit, seeds and nuts. The eastern chipmunk defends its burrow and lives a solitary life, except during mating season. Their forefeet have four toes and their hindfeet have five. The other 24 species live primarily in the United States and Canada. They typically have only one litter of up to seven young, which are born in May or June. During a brief estrous period, females mate with multiple males. After a gestation period of about thirty days, two to seven young (usually four or five) are born. Chipmunks eat a wide variety of seeds, fruits and nuts. However, cache defending behaviors were deterred in this study. Each bears a litter of 2-9 young, (average 4-6) 31 days later within the underground nest. the business of buying and selling animals for people to keep in their homes as pets. It can climb trees well, but constructs underground nests with extensive tunnel systems, often with several entrances. Diet: Chipmunks eat mainly seeds and nuts, but also consume mushrooms, fruits, berries, corn, small invertebrates, bird eggs, and sometimes small vertebrates. Typically females in estrous stay within their home range and males come from outside areas to mate. Their burrow is typically in the center of a roughly circular home range, the primary use area has a radius of 15 to 25 meters from the entrance. At six-weeks old, they are weaned and leave the burrow for the first time. Chipmunks may arise frequently to feed and during mild winter weather they may forage above ground. Eastern chipmunks are polygamous. Winters are spent underground. Light and dark stripes occur on their face around their eyes. To hide the construction of its burrow, the eastern chipmunk carries soil to a different location in its cheek pouches. Draw an eastern chipmunk and send it to ChiTribuneGraphics@gmail.com -- we'll upload it onto our Tumblr page, which can be seen here. Caching behavior is determined by the moisture content of the environment. living in cities and large towns, landscapes dominated by human structures and activity. They are very adaptable and can burrow under buildings or create nests in basements and barns. The other calls are typically given when a predator is spotted. Chipmunks have special, expandable pouches in their cheeks that they can stuff with food in order to carry it back to the larder. "[3], A small species, it reaches about 30 cm (12 in) in length including the tail, and a weight of 66–150 g (2.3–5.3 oz). (Da Silva, et al., 2002; Kurta, 1995; Smith, 2005), Most eastern chipmunks survive less than two years, but there are accounts of chipmunks living up to eight years. By the eighth day of life, their stripes begin to appear. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico. Their sides and back have five dark stripes; the longest stripe occurs along their midline. The eastern chipmunk has reddish-brown fur on its back and sides and white fur on its stomach. Chipmunks distribute soil to the surrounding areas or use it to close an old entrance to the burrow. In the early summer and early fall, their range is the largest. The eastern chipmunk is found abundantly throughout the middle and eastern sections of the United States. "Tamias striatus" (On-line), Animal Diversity Web. Reproduction & Family Structure The eastern chipmunk has two litters of two to five pups each year: once in the spring and again in midsummer. living in the Nearctic biogeographic province, the northern part of the New World. This could be because males are uncertain of kinship and trilling would put an individual at higher risk. Their range extends from Nova Scotia, east to Saskatchewan and south to Oklahoma, where they occupy the eastern part of the state. Siberian chipmunk is a species of rodents native to northern Asia. - NatureWorks November 11, 2012 - NatureWorks An important difference between the two species in this context is reproduction. Newborn least chipmunks are pink and have no fur. A common and abundant species across its range, this diurnal squirrel is very clever at avoiding detection when needs be. Foraging occurs mostly along the ground, but eastern chipmunks are proficient climbers. Like other chipmunks, it transports food in pouches in its cheeks. living in residential areas on the outskirts of large cities or towns. (Da Silva, et al., 2002; Kurta, 1995; Saunders, 1988) Mating System; polygynous Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Riedel D. Trypanosoma (Herpetosoma) tamiasi sp. an animal that mainly eats all kinds of things, including plants and animals. Trills are shorter in duration and are given during pursuit by a predator. Some females may produce a second litter if their first litter is lost. They are not native to Newfoundland, but have been introduced. Both species showed signs of being very selective in choosing cache locations to prevent their caches from being robbed. Smith, J. In more aggressive eastern chipmunks, larder hoarding is more beneficial because a single, large cache is easier to defend than several small caches. Chipmunks are lively little creatures that are found […] 2001. Individuals that do not disperse have home range lengths of up to 0.5 km throughout their lifetime. An important difference between the two species in this context is reproduction. [5], Eastern chipmunks are known to be one of many hosts for the parasitic larvae of Cuterebra botflies. Adult females are most likely to trill when close (10 m from the burrow) to relatives. Eastern chipmunks are found throughout eastern Canada and eastern United States. Search in feature The stripe along their body distinguishes them from all other rodents except least chipmunks. Territorial calls lead to aggressive behavior when another individual is present. It is less profitable for eastern chipmunks to rob the caches of least chipmunks. eastern chipmunk’s reproduction as a function of beech seeds production. The Eastern Chipmunk is a small, ground-dwelling squirrels, which are frequently observed with full cheek pouches, occur all across Tennessee.. Accessed the area in which the animal is naturally found, the region in which it is endemic. Reproduction: Breeding occurs twice per year - once in the spring and once in the summer - when chipmunks give birth to 4-5 babies at a time. Females give birth to a single litter of 2 to 6 young in May or June. ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Chipmunks are the smallest members of the squirrel family, according to National Geographic. 2002. Habitat They live in open deciduous forests (trees with leaves that fall each autumn). Reproduction & Longevity. Least chipmunks benefit from the larger caches of eastern chipmunks, which store up to four times as many seeds. 2011. gonochoric/gonochoristic/dioecious (sexes separate), Max Planck Institute for Demographic Research, http://www.turtletrack.org/Issues01/Co01132001/CO_01132001_Chipmunkstripes.htm, http://www.stolaf.edu/depts/environmental-studies/courses/es-399%20home/es-399-05/Projects/Jared's%20Senior%20Seminar%20Research%20Page/, © 2020 Regents of the University of Michigan. Eastern Chipmunk – This common little rodent ranges throughout much of the eastern United States and into Canada. National Science Foundation Also, least chipmunks' olfactory cues are weak in comparison. A study of the Eastern Chipmunk in the Adirondack Mountains suggests a spring mating season between February and April, with litters merging above ground in late spring (April to June), and a summer mating season from June to August, with litters emerging above ground in early fall (August to October). A female may bear two litters, the first in April - June, and a second in August - October, or just one litter in late summer. Reproduction : Breeding takes place in March, and mating chases are spirited, with several males pursuing a female. Eastern chipmunks are not noted for causing this type of damage. The gestation period lasts about a month. Chipmunks mate twice a year from February to April and again from June to August. "Tamias striatus. Ethology, 106: 1057–1066. The eastern chipmunk has light stripes above and below its eyes and it has pouched cheeks that it uses to store and carry food. Life Cycle/Reproduction: Eastern chipmunks mate in early spring and sometimes again in late summer, depending on their age, food availability and the duration of snow. The f… Because of their abundance, chipmunks are a valuable prey item for a variety of species. Litters of 4 – 5 young are produced after a gestation period of 30 days. Reproduction: Chipmunks become sexually mature at 1 year. Eastern chipmunks increase vigilance, run shorter more direct distances and delay emergence from burrows after hearing an alarm call, which suggest that the calls directly affected behavior. Da Silva, K., C. Mahan, J. Da Silva. Reproduction, structure and host specificity of Trypanosoma (Herpetosoms) tamiasi sp. Journal of Comparative Psychology, 125(4): 375-384. 2: 546-552.

It has two fewer teeth than other chipmunks and four toes each on the front legs, but five on the hind legs.[5]. High intense chases establish hierarchies among groups of males competing for access to females, individuals display aggressive and submissive postures during these behaviors. To do this, she will dig new entrances into her burrow although never using them. (Kurta, 1995; Snyder, 1982), Eastern chipmunks are polygamous. They also are important to spore dispersal for different kinds of fungi. having the capacity to move from one place to another. Their prime habitat is mature beech-maple forests, but they will occupy bushy areas and coniferous forests, however, swampy sites are avoided. Topics Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. 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.

[5] The two breeding seasons are from February to April and from June to August. ... Reproduction. Eastern chipmunks have two breeding season, one of which occurs from February to April, and the other lasts from June to August. Two to 5 young are born in April or May, and again in August or October. forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality. Frequency: The Eastern chipmunk is a very common species in the Shawangunks. This increases an individual’s overall fitness by helping related individuals. "Small Mammals and Agriculture: A Study of Effects and Responses" (On-line). Ecoscience, 18(2): 130-137. Plant-animal interactions and climate: Why do yellow pine chipmunks (Tamias amoenus) and eastern chipmunks (Tamias striatus) have such different effects on plants?. On average, males travel 170 meters from their burrow to mate. having more than one female as a mate at one time, breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female, places a food item in a special place to be eaten later. Ann Arbor, MI: University of Michigan Press. The primary function of trill calls is likely to warn nearby relatives of predators. Trilling occurs in all active seasons, not just during juvenile emergence, which discounts the hypothesis that trilling is a mechanism of parental care.

Chipmunks are mainly active during the day, spending most of their time foraging for food. The ground squirrels are members of the squirrel family of rodents (), which generally live on or in the ground, rather than trees.The term is most often used for the medium-sized ground squirrels, as the larger ones are more commonly known as marmots (genus Marmota) or prairie dogs, while the smaller and less bushy-tailed ground squirrels tend to be known as chipmunks (genus … Description: The Chipmunk is mostly reddish-brown, with five lengthwise dark brown to blackish stripes running from shoulders to rump, each with white fur … This ground dwelling mammal inhabits open deciduous forests where cover is readily available in the form of stumps, logs or rocky outcrops. They are very adaptable and can burrow under buildings or create nests in basements and barns. Baack, J., P. Switzer. Chipmunk Reproduction Chipmunk breeding season occurs in early spring and then again in early summer. Adults live up to three years in the wild. This material is based upon work supported by the They have a litter of two [4] It has reddish-brown fur on its upper body and five dark brown stripes contrasting with light brown stripes along its back, ending in a dark tail. referring to animal species that have been transported to and established populations in regions outside of their natural range, usually through human action. While feeding, chipmunks often help to disperse seeds of plants and spores from fungi. Typical population density is 10 to 22 chipmunks per hectare. Lifespan of this rodent in the wild is only 2-3 years. Typically females in estrous stay within their home range and males come from outside areas to mate. Accessed Eastern chipmunks defend their home ranges. Life Cycle/Reproduction: Eastern chipmunks mate in early spring and sometimes again in late summer, depending on their age, food availability and the duration of snow. Frequency: The Eastern chipmunk is a very common species in the Shawangunks. However, their occasional scatter-hoarding behavior can be beneficial in seedling establishment. (Da Silva, et al., 2002; Kurta, 1995; Linzey, 2008), Eastern chipmunks are small rodents with grayish to reddish brown fur and a distinguishing yellowish to reddish patch on their rumps. Food is transported within cheek pouches located on either side of the mouth. During the winter, the chipmunk may enter long periods of torpor, but does not truly hibernate. (Smith, 2005). Gestation period lasts for 35 days, yielding a litter of 2 - 5 young, typically in an underground nest. Kurta, . [12] It is smaller than T. s. griseus but larger than the least chipmunk (Neotamias minimus). Juvenile females trill at a lower rate than adults, this may indicate their higher predation risk or smaller fitness gain. Eastern chipmunks are noticeably larger than least chipmunks, which helps to distinguish between the two species. (Da Silva, et al., 2002; Kurta, 1995; Saunders, 1988), Eastern chipmunks produce two litters per year; one in early spring and one in midsummer. The gestation period is 31 days. Mammalian Species, 168: 1-8. (Baack and Switzer, 2000; Da Silva, et al., 2002; Saunders, 1988), Eastern chipmunks react to alarm calls by altering their foraging behavior and becoming more alert.

There are three genera in this family: Tamias (eastern North America), Neotamias (western North America) and Eutamias (Eurasia). (Kurta, 1995; Penner and Devenport, 2011), In a study of captive chipmunks, eastern chipmunks demonstrated less success than least chipmunks in cache pilfering behavior. Home range size varies from 800 to 6,000 m2. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. It can climb trees well, but constructs underground nests with extensive tunnel systems, often with several entrances. Some dispersal, up to 0.9 km, will occur. n. is described from blood and organs of the eastern chipmunk, Tamias striatus, and the least chipmunk, Eutamias minimus. Click to expand.
