Ever spot a tiny, striped critter darting across your yard and think, wait, is that just a squirrel? Well, yeah—chipmunks are actually a kind of squirrel. They’re just smaller, with some quirks that make them stand out from their fluffier-tailed relatives.
Knowing this makes it a little easier to appreciate those busy little creatures scampering around the neighborhood.
Chipmunks have bold stripes down their backs and heads. You’ll usually find them scurrying along the ground, not leaping through trees like the classic squirrels.
They’ve got these adorable cheek pouches for stashing snacks—pretty handy if you ask me. Curious about how chipmunks really differ from other squirrels? Let’s dig in.
Are Chipmunks Actually Squirrels?
So, are chipmunks just squirrels in disguise? They share a family tree but have some pretty unique habits and looks.
If you want to tell them apart, it helps to know what makes each one tick.
Chipmunk and Squirrel Family Classification
Chipmunks and squirrels both fit into the rodent group, Rodentia, and more specifically, the squirrel family, Sciuridae.
This family covers tree squirrels like the eastern gray, flying squirrels, ground squirrels, woodchucks, and, of course, chipmunks.
Chipmunks fall under the subtribe Tamiina within the squirrel family. For example, the eastern chipmunk is Tamias striatus, and the least chipmunk is Tamias minimus.
Most chipmunks live on the ground, but not every ground squirrel counts as a chipmunk.
The Siberian chipmunk (Eutamias sibiricus) lives in Asia, while most others stick to North America. So, chipmunks are definitely squirrels, just a very specific, striped group in the big squirrel family.
Chipmunk vs. Squirrel Appearance
Chipmunks are tiny compared to most squirrels. Usually, they reach about 5-6 inches long, not counting the tail.
Eastern gray squirrels, on the other hand, can stretch up to 16 or even 20 inches.
You can spot a chipmunk by its stripes running down its back and face—hence the nickname “striped squirrels.” Squirrels like eastern gray or fox squirrels don’t have those stripes; their fur is pretty uniform.
Chipmunks have small, round bodies and short legs, perfect for digging. Squirrels look bigger, with bushy tails and longer legs for climbing.
Flying squirrels are a whole different story—they’ve got skin flaps for gliding, something chipmunks totally lack.
Key Differences Between Chipmunks and Other Squirrels
Behavior and habitat really set them apart. Chipmunks spend most of their time digging and living in burrows underground.
Their tunnels can stretch over 11 feet and have special rooms for food and sleeping.
Tree squirrels mostly live up high in nests. While both eat seeds and nuts, chipmunks love to stuff their cheek pouches and hoard food for winter.
Chipmunks often hibernate or just hunker down with their food stash during cold months, especially eastern chipmunks. But many squirrels stay active all year.

Chipmunk Species, Behavior, and Diet
Chipmunks come in a surprising number of species, each with their own quirks and favorite hangouts.
Their daily routines, what they eat, and how they “talk” all help them survive wherever they end up. You’ll spot them in forests, rocky places, and sometimes not far from people’s homes.
Common Chipmunk Species and Distribution
There are about 25 species of chipmunk out there. The Eastern chipmunk (Tamias striatus) pops up mostly in eastern North America.
The Least chipmunk (Tamias minimus) hangs out in the western U.S. and Canada.
The Siberian chipmunk (Eutamias sibiricus) is a bit of an outlier, living mostly in Asia. In western North America, you’ll find the Yellow-pine chipmunk (Neotamias amoenus).
Most chipmunks stick to the ground but can climb pretty well when they have to. Their burrows usually have hidden entrances to keep them safe from predators like bobcats.
Behavior and Habits of Chipmunks
Chipmunks are daytime creatures. Most of the time, you’ll spot them dashing around, grabbing food, or keeping an eye out for threats.
They dig pretty complex burrows—sometimes up to 11 feet long—with special rooms for sleeping and food storage.
Some chipmunks, like the eastern chipmunk, hibernate during winter. Others just stay put in their burrows, living off their hidden food.
They usually keep to themselves, except during mating season.
Chipmunks have to stay quick and alert to dodge predators. All that scurrying helps spread seeds and fungi, which is actually great for the environment.
Chipmunk Diet and Foraging
Chipmunks eat all sorts of things. Their main diet includes seeds, nuts, fruits, and buds.
They’re pretty fond of fungi, too, which helps spread spores that trees need to grow.
Sometimes, they’ll grab insects, bird eggs, worms, or even tiny frogs. If you’ve got a garden, you might notice them stealing a few veggies or grains, which can be a bit annoying.
Those cheek pouches come in handy—they let chipmunks haul loads of food back to their burrows. In autumn, they really go all out gathering and storing food, making sure they’ve got plenty to last through winter.
Chipmunk Calls and Communication
Chipmunks make all sorts of sounds to talk to each other. Sometimes you’ll hear quick chirps or even a trill—usually, that’s their way of warning everyone about danger, like when a bobcat is lurking nearby.
They don’t just rely on sounds. During mating season, chipmunks call out, and they use different calls to mark their territory too. You’ll notice they flick their tails or move their bodies in certain ways, which adds a whole other layer to how they communicate.
If you listen closely, you can pick up on when chipmunks feel threatened or when they’re just chatting with each other. These calls really help them stay safe and connected in their world.
