Types of Chipmunks in Arizona
Arizona is home to two main types of chipmunks: the Cliff Chipmunk and the Colorado Chipmunk. Both are small, striped ground squirrels most active in daylight, often seen near rocky outcrops and pine forests. Look for them in the higher elevations of the state, especially in the Mogollon Rim and Sky Islands.

1. What are the most common chipmunk species in Arizona?
The two chipmunks you are most likely to encounter in Arizona are the **Cliff Chipmunk** (*Neotamias dorsalis*) and the **Colorado Chipmunk** (*Neotamias quadrivittatus*). The Cliff Chipmunk is widespread across central and northern Arizona, while the Colorado Chipmunk is limited to the northeastern corner, near the Colorado Plateau. A third species, the Gray-footed Chipmunk, appears only in a tiny area near the Arizona-New Mexico border.
In Arizona, chipmunks sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow...
2. How can you tell the Cliff Chipmunk from the Colorado Chipmunk?
Start with the stripes on the face and back. The Cliff Chipmunk has a bold dark stripe through the eye, a white stripe above and below it, and five dark back stripes separated by pale ones. The Colorado Chipmunk looks similar but tends to have paler, less contrasting stripes and a slightly grayer tail. The best field mark: Colorado Chipmunks have a reddish rump that the Cliff Chipmunk lacks. Check out ourchipmunk identification guidefor side-by-side photos.
3. Where in Arizona are you most likely to see each type?
Cliff Chipmunks are the default from the Mogollon Rim south through the Sky Islands, including the Chiricahuas and Santa Catalinas. They stick to rocky slopes, canyons, and pine-oak woodlands. Colorado Chipmunks are restricted to the far northeast, around the Kaibab Plateau and the Colorado River corridor near Page. For the Gray-footed Chipmunk, your best bet is the White Mountains around Greer and Alpine. TheArizona wildlife sectionhas detailed maps.
4. When is the best time to spot chipmunks in Arizona?
Chipmunks are active from early spring to late fall, typically between 6 a.m. and 10 a.m. in the morning and again in the late afternoon. They are less active during the hottest part of the day, especially in summer. Look for them near rock piles, fallen logs, or under shrubs. They often perch on rocks or low branches to scan for predators.

5. What should you bring to identify chipmunks in the field?
A pair of binoculars (8x or 10x is fine) and a simple field guide or phone app with range maps will help. Take notes on stripe patterns and tail color. If you visit areas like theMogollon Rimor the North Rim of the Grand Canyon, you'll have the best odds of seeing both species in one trip.
6. Do Arizona chipmunks behave differently from other chipmunks?
Not much. They are ground foragers, storing seeds and berries in cheek pouches. They are diurnal and will often sit upright on rocks. The Cliff Chipmunk is especially bold around campgrounds and picnic areas, whereas the Colorado Chipmunk tends to stay closer to forest cover. Both species hibernate in winter, emerging in March or April.
