Their color varies from grayish to reddish-brown with a cream or white underside. There are five brown or black lines separated by four cream or white stripes running down their back. Two light and two dark stripes run from the tip of the nose through the eye and the top of the head. The bushy tail is orangish-brown. These hyperactive rodents are found busy gathering nuts, berries, seeds, and insects during the daylight hours. Because of their diurnal habits exposure to nocturnal hunters like owls, foxes, raccoons, weasels, and other predators is minimized. Although animals such as hawks and snakes, that are active when chipmunks are scurrying around, will still snatch one for a quick meal when they can. And when I say quick, I mean it. These speedy little chipmunks can run at speeds up to four and half miles per hour! They are not only fast, but they are also great climbers and jumpers, so any predator bent on a least chipmunk meal is going to have to work for it.]
The least chipmunk is often mistaken for the yellow pine chipmunk that shares much of the same range and habitats. The YPC is bigger and much more territorial, often chasing the smaller least chipmunk away from available food sources. Despite this apparent bullying behavior, the least chipmunk is able to survive on less food than most chipmunks and tend to be more plentiful in areas where food sources are scarce.
These little chipmunks are not true hibernators like bats, and other mammals. Instead, they enter into a type of slumber called torpor. They will slow their metabolic rate and reduce their body temperature, which reduces their need for food. They do not pack on fat like other animals do before a long winter of hibernation. Many times, during the winter they will wake up and seek out their caches of food for a quick meal and find water if available before going into a deep sleep again. When spring returns, they are active again. On cooler days, these little chipmunks often climb trees seeking out a higher vantage point to bask in the sun and warm themselves.
The biggest challenges facing chipmunks are human activity. This comes in the form of habitat destruction as well as poisoning and trapping. Many people consider chipmunks pests and target them much like other rodents. However, least chipmunks pose no significant issues for humans, other than maybe in campgrounds where they tend to beg for treats in a form of conditioning. Who hasn’t tempted a chipmunk closer to them with a tasty peanut or piece of granola? Once a chipmunk associates a human with an easy food source they will hang out where the humans are.
The Iroquois tribe talks of how the chipmunk got his stripes. Back when the animals were in charge of making big decisions such as whether we should have eternal night or night and day, the bear being the biggest and the strongest of all animals climbed to the highest mountain. Deer, raccoon, chipmunk, wolf, and many others followed. On top of the rocky, treeless mountain the bear growled in his strongest voice that the world should have only darkness. The Wolf and raccoon, being too scared to do otherwise, agreed with bear. However, the tiniest animal of all, the chipmunk spoke up against the bear. He wanted there to be both daylight and darkness. The bear grumbled, and growled, and said, “No! Darkness only!” The chipmunk continued to chatter and talk and kept the bear so distracted all night long that the sun began coming up in the East. The other animals having never seen a sunrise before were mesmerized by the beauty. The bear realizing what had happened was angry at the chipmunk and quickly chased him down the mountain. Bear was fast and reached out with his giant paw, but chipmunk got away, although not before bears long claws scratched his back. To this day you can see the stripes on the chipmunks back.
