You may see chipmunks and squirrels in the same yard and assume they are the same animal. They are closely related, but they are not identical.
You can usually tell them apart with a few quick clues. Chipmunks are a smaller, striped branch of the squirrel family, while squirrels cover a much wider group of animals.
If you know what to look for, spotting the difference becomes much easier. Size, tail shape, stripes, and where each animal spends its time all give you strong clues in the field.
The Short Answer And Family Relationship
Chipmunks and squirrels both belong to the sciuridae family, so they are related. That family includes many squirrel species, plus chipmunk species, ground squirrels, and flying squirrels.
Why They Are Related But Not Identical
The difference is similar to comparing a small branch of a family tree with the whole tree. A chipmunk is one kind of squirrel, while squirrels as a group include many body shapes, sizes, and lifestyles.
How Chipmunks Fit In The Sciuridae Family
Chipmunks belong to the sciuridae family and the rodent order, Rodentia, just like other squirrels. In classification terms, they sit inside the larger squirrel group.
All Chipmunks Are Squirrels, But Not All Squirrels Are Chipmunks
Chipmunks are a specific kind of squirrel. Types of squirrels also include tree squirrels, ground squirrels, and flying squirrels.
A chipmunk vs squirrel comparison is really a comparison between a subgroup and a broader group.
How To Tell Them Apart At A Glance
A quick look often tells you enough to make a good guess. Focus on body size, striping, and tail shape, then check whether you are looking at a woodland climber or a low-running ground animal.
Size, Stripes, And Overall Body Shape
Chipmunks are usually much smaller and slimmer than most squirrels. They often have bold stripes down the back and sides, while many squirrels are unstriped and look rounder through the body.
Bushy Tails Versus A Typical Chipmunk Tail
A chipmunk tail is usually smaller and less fluffy than the big, bushy tail you see on many tree squirrels. If the animal has a thick, plume-like tail, it is more likely a squirrel than a chipmunk.
Chipmunk Vs Ground Squirrel In Real-World Sightings
A chipmunk vs ground squirrel sighting can be tricky because both stay low to the ground. A ground squirrel may also show stripes, as with the thirteen-lined ground squirrel, so shape and behavior matter as much as markings.
Chipmunks often dart toward burrow openings. Many ground squirrels move with a slightly larger, more open-bodied look.
Habitat, Behavior, And Daily Life
Where they live tells you a lot about how they act. Chipmunks choose underground shelter, while many squirrels spend more time above ground in trees, especially tree squirrels and flying squirrels.
Burrows Compared With Tree Nests
Chipmunks dig burrows and use them for shelter and food storage. Tree squirrels usually build nests called dreys from twigs and leaves high in trees, which gives them a safer place to rest and raise young.
Ground Movement Compared With Tree Climbing
Chipmunks tend to stay close to the ground and move in quick bursts. Tree squirrels climb, leap, and cross branches with ease.
Flying squirrels glide between trees and stay tied to wooded habitats.
Diet, Food Storage, And Winter Activity
Both animals forage for nuts, seeds, fruit, and other plant foods. Chipmunks often carry food back to their burrows, while squirrels may stash food in scattered hiding spots or nests.
In the U.S., both are especially busy in fall as they prepare for winter, as noted by A-Z Animals.
Common Species People Usually Notice
The species you notice most depend on where you live. In many U.S. neighborhoods and woodlands, a few familiar chipmunks and squirrels show up again and again.
Eastern Chipmunk And Least Chipmunk
The eastern chipmunk is one of the most familiar chipmunks in the eastern United States. The least chipmunk is another common one, especially in western and northern areas.
Both are small, striped, and quick around low cover.
Siberian Chipmunk In Broader Context
The siberian chipmunk is important as a regional example, since it is not one of the common wild chipmunks you are likely to spot in everyday U.S. settings. You are more likely to encounter it outside the U.S. or in captivity.
Eastern Gray Squirrel And Other Familiar Squirrel Types
You probably see the eastern gray squirrel most often in U.S. parks and neighborhoods.
It is larger than a chipmunk and usually unstriped.
Other familiar squirrel types include fox squirrels and red squirrels.
