What chipmunk species live in Washington?
Washington has four chipmunk species: the least chipmunk (*Tamias minimus*), Townsend's chipmunk (*Neotamias townsendii*), yellow-pine chipmunk (*Neotamias amoenus*), and the red-tailed chipmunk (*Neotamias ruficaudus*). The least and Townsend's are the most widespread. The yellow-pine chipmunk is common in the eastern mountains, while the red-tailed chipmunk is found in northeastern forests.

How can you identify the least chipmunk?
The least chipmunk is the smallest, about 7-8 inches long including the tail. It has a white stripe above and below a dark stripe on each side, and a narrow white stripe between the eyes. Its tail is reddish and less bushy than other species. You'll see them in dry, open pine forests and sagebrush areas, especially east of the Cascades.

How can you identify Townsend's chipmunk?
Townsend's chipmunk is larger, 9-11 inches long, with duller stripes and a brownish-gray coat. The white stripes on the face are less distinct, and the underside is grayish. Its tail is bushy and brown. This species prefers moist, dense forests west of the Cascades, from sea level to subalpine zones. Look for them on the Olympic Peninsula and in the Cascade foothills.
Where can you find yellow-pine chipmunks in Washington?
Yellow-pine chipmunks inhabit the eastern slopes of the Cascades and the Rocky Mountain region of northeastern Washington. They are named for their preference for yellow pine forests, but also live in mixed conifer woods. They are similar to the least chipmunk but slightly larger, with a yellowish tint on the sides and a more rounded head. The best times to spot them are early morning and late afternoon in open forest edges.

How do you distinguish chipmunks from ground squirrels?
Chipmunks have five dark and light stripes on the back and face, while ground squirrels typically have no face stripes and a less distinct back pattern. Chipmunks also have a flattened, bushy tail that they often hold upright. Ground squirrels are larger, with a more useful body. For more identification tips, see ourWashington wildlife guide.
What seasons are best for chipmunk spotting?
Chipmunks are active from early spring (March) through late fall (October). They are most visible during the warmer months when gathering food. Peak activity occurs in mid-morning and late afternoon. In winter, they hibernate in burrows, so sightings are rare. If you want to see chipmunks in Washington, plan your hikes between April and September.
