Foraging occurs mostly along the ground, but eastern chipmunks are proficient climbers. The frequency range is similar to the ones adopted by Eastern chipmunks. (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. Eastern chipmunks establish a home range of roughly 40m, which consists of a tightly defended area around a burrow and a larger less defended area beyond 40m in which the animal tolerates others (Wilson and Ruff 1999; Baker 1983). This ground dwelling mammal inhabits open deciduous forests where cover is readily available in the form of stumps, logs or rocky outcrops. Stripes on the face distinguish this species from all other mammals over most of its range. The eastern chipmunk is a small, ground-dwelling squirrel with conspicuous lengthwise stripes on the back, sides, and cheeks. Baack, J., P. Switzer. The ADW Team gratefully acknowledges their support. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends.

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. Acknowledgements | Mission Statement | Juvenile females trill at a lower rate than adults, this may indicate their higher predation risk or smaller fitness gain. (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. living in residential areas on the outskirts of large cities or towns. (Da Silva, et al., 2002; Kurta, 1995; Linzey, 2008), Eastern chipmunks are extremely vocal and produce a variety of chips, trills and calls to alert others to the presence of predators or for territory defense. Some dispersal, up to 0.9 km, will occur. Their tail is hairy, but not bushy and is somewhat flattened. living in the Nearctic biogeographic province, the northern part of the New World.

Eastern Chipmunk The Eastern chipmunk may be one of New York's most abundant and easily recognized small mammals. 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. Order: Rodentia Some dispersal, up to 0.9 km, will occur. The neonates are weaned 40 days after birth. The nest may be as much as 0.9 m (3 ft) below the soil surface and 1.8 - 3.7 m (6 - 12 ft) away from the burrow entrance. Eastern Chipmunk (Tamias striatus) responses in home range to artificial food supplementation. They are solitary and territorial, especially close to their burrow. Chipmunks are the smallest members of the squirrel family, according to National Geographic. Typical population density is 10 to 22 chipmunks per hectare. Other foods include insects, small amphibians and birds. Young become independent two months after birth. This is mostly due to their size and the fact that they provide the most meat to a hunter.

Males trill farther from the burrow, 100 m or greater. a b Fig. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico. Chipmunks live in elaborate underground burrow systems with interconnecting tunnels, a nest area, and an area for food storage. Their sides and back have five dark stripes; the longest stripe occurs along their midline. After an alarm call, they expend greater energy and spend more time exposed at feeding stations because they decrease the amount of food carried to caches after hearing the call. The stripe along their body distinguishes them from all other rodents except least chipmunks. Eastern Chipmunk The Eastern chipmunk may be one of New York's most abundant and easily recognized small mammals.

Eastern chipmunk population densities may be as high as 10 animals per acre (24/ha), however, if sufficient food and cover are available. In more aggressive eastern chipmunks, larder hoarding is more beneficial because a single, large cache is easier to defend than several small caches. Chucking sounds are produced by Western chipmunks as well. They reach as far north as the treeline, where it is too cold and dark for forests to grow. Each critter also has its own range. The home range consists of a core area that is approximately seventy-five square feet from the burrow. Chipmunks range in size from 8 to 10 inches long (including the tail) and weigh between 2 to 5 ounces.

Throughout its range, the Eastern Chipmunk is at home in a variety of habitats. Eastern chipmunks give three distinct calls: chipping, chucking and trilling. Size. Most conflicts with chipmunks are nuisance problems. Many studies have shown that the size of home ranges vary due to several factors including food abundance (Mares et al. 2001.
