Still, when humans are around to feed them peanuts and other goodies, they are often seen with other least chipmunks. Baker, ; Bergstom, ; Hamilton and Whitaker, ; Kurta, Some areas have up to 6 individuals per acre.
Banfield, Like other squirrels that are active during the day, vision is an important part of commmunication. Visual signals, such as body posture and tail movement, deliver important information to other chipm. Sounds are also used in the communication of these animals. Least chipmunks use calls to advertize their ownership of a territory, to find mates, and when they feel threatened.
Touching lets some chipmunks communicate. This is especially important between mothers and their offspring. It is also important for mates and rivals. The role of scents in chipmunk communication has not been described. Smells are likely tpo be important in helping chipmunks recognize one another. Baker, ; Bergstom, Least chipmunks eat a wide variety of foods. Their diet including nuts, berries, fruits, grasses, fungi, snails, insects, and possibly some small birds and mammals.
From April through October, much of a chipmunk's time is spent foraging. Least chipmunks forage both on the ground and in trees at heights up to 9 m Kurta, Cheek pouches allow individuals to carry multiple food items back to their burrows, where they are either eaten or stored for future use. Baker, ; Bergstom, ; Kurta, Major threats to these animals include weasels , goshawks, Cooper's hawks, snakes, mink , red fox , bobcats , and martens , as well as domestic dogs and cats.
As animals that carry nuts and seeds from one place to another, least chipmunks are probably very important in seed dispersal. They also play and important role as a food source to their predators. They also provide habitat for a number of parasites. Least chipmunks have no significant negative impacts on humans, though they may occasionally be a nuisance to campers Hamilton and Whitaker, Least chipmunks are predators of pest insects and may play a role in seed or pollen dispersal.
The primary threat to least chipmunks is habitat loss caused by the encroachment of humans. Hunting or trapping may also pose a small threat. Currently least chipmunk populations are steady. Baker, R. Michigan Mammals. Banfield, A. The Mammals of Canada. Toronto: University of Toronto Press.
Bergstom, B. Least Chipmunk Tamias minimus. Smithsonian Book of North American Mammals. Washington, D. Burt, W. The Mammals of Michigan. Hamilton, W. Winter nests are located in underground burrows that consist of dried grass, bark, fur, feathers and soft vegetation Kurta, With the onset of cold weather, chipmunks retire to these burrows, where they enter torpor and live off stored food until spring Kurta, Hibernation in these animals is not as deep as it is in ground squirrels, and they awake frequently to snack on stored food during the winter months Bergstom, Least chipmunks are territorial and will defend their nests from invaders.
Least chipmunks are diurnal. In general, they are not social, except for mating and rearing young. However, when provisioned by humans, they are remarkably tollerant of conspecifics Bergstrom, Baker, ; Bergstom, ; Hamilton and Whitaker, ; Kurta, Some areas have up to 6 individuals per acre. Banfield, Like other diurnal sciurids, vision is an important part of commmunication.
Visual signals, such as body posture, convey important information to conspecifics. In addition to visual communication, these animals use a variety of auditory signals to communicate.
They use calls to advertize their ownership of a territory, to find mates, and when they feel threatened. Tactile communication is important between mothers and their offspring, as well as between mates and rivals. The role of olfactory cues in this species have not been described, but scents are often important in individual recognition. It is likley that there are some chemical cues used by these chipmunks in communication. Baker, ; Bergstom, Least chipmunks eat a wide variety of foods.

Hunting or trapping may also pose a small threat. Currently least chipmunk populations are steady. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico.
In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. 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.
Convergent in birds. The act or condition of passing winter in a torpid or resting state, typically involving the abandonment of homoiothermy in mammals.
Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes. Coniferous or boreal forest, located in a band across northern North America, Europe, and Asia. This terrestrial biome also occurs at high elevations. Long, cold winters and short, wet summers. Few species of trees are present; these are primarily conifers that grow in dense stands with little undergrowth. Some deciduous trees also may be present.
Baker, R. Currently least chipmunk populations are steady. Comments : May be active throughout the day, but prefers the sunny midday hours. Begins semihibernation in late October. Fully active by mid-March. May be active on warm winter days. The least chipmunk is the smallest and most widely distributed North American chipmunk.
It occurs in a variety of habitats, from coniferous forests to meadows to sagebrush desert, feeding primarily on seeds but also eating flowers, buds, leaves, grasses, fungi, and even insects, eggs, and carrion. Least chipmunks are diurnal, like all ground-dwelling members of squirrel family.
They retreat to their burrows at night and spend the winter underground, periodically waking up to feed on stored food. They scatter-hoard, storing seeds all over the place, so they unwittingly help many species of plants sprout in new places. Links: Mammal Species of the World. In addition, they are found throughout central and western Canada and in parts of Wisconsin, Minnesota and Michigan. Least chipmunks eat a wide variety of foods. Their diet including nuts, berries, fruits, grasses, fungi, snails, insects, and possibly some small birds and mammals.
From April through October, much of a chipmunk's time is spent foraging. Least chipmunks forage both on the ground and in trees at heights up to 9 m Kurta, Cheek pouches allow individuals to carry multiple food items back to their burrows, where they are either eaten or stored for future use. Animal Foods: birds; mammals; carrion ; insects; terrestrial non-insect arthropods; mollusks; terrestrial worms. It is the most widespread species of chipmunk in North America occurring across north-central and western United States and from British Columbia and southern Yukon to western Quebec in Canada.
They are often found near rock cliffs, river bluffs, and open jack pine stands. Least chipmunks are found throughout the boreal and temperate forests of North America. However, least chipmunks prefer more open areas such as forest edges and openings. They are also commonly found near rock cliffs, river bluffs, and open jack pine stands. Comments : Found in various habitats. Common in coniferous forests but also uses clearcuts, deciduous woods, sagebrush, riparian zones, and in western regions may even occur in alpine tundra.
Winter nest up to 1 m below ground surface.
