When chipmunk are recorded in Missouri
Missouri is home to two species of chipmunks: the eastern chipmunk (Tamias striatus) and the least chipmunk (Tamias minimus). The eastern chipmunk is widespread across the state, while the least chipmunk is limited to the northwestern corner. Start by looking for the telltale stripes and cheek pouches to tell them apart.
1. What chipmunk species live in Missouri?
Missouri hosts two chipmunk species: the eastern chipmunk and the least chipmunk. The eastern chipmunk is by far the more common and is found statewide in wooded areas. The least chipmunk has a much smaller range, primarily in the northwest near the Missouri River bluffs. Both belong to the genus Tamias but have distinct habitats and markings. For a complete overview, check ourchipmunk identification guide.
2. How do you identify an eastern chipmunk?
The eastern chipmunk is about 5-6 inches long with a brownish body, five dark stripes (one central, two on each side), and a reddish-brown rump. It has a white stripe above and below the eye, and a bushy tail that is slightly flattened. You’ll often see them with full cheek pouches carrying acorns or seeds. They are most active in early morning and late afternoon, especially in oak-hickory forests.
3. How do you identify a least chipmunk?
The least chipmunk is smaller, about 4-5 inches, with a grayer coat and more distinct stripes. It has a white stripe between two dark stripes on the face, and the body stripes extend to the tail base. Its tail is narrower and less hairy. In Missouri, the best chance to see one is in the northwest, particularly in rocky, open woodlands near grasslands. They are more shy than eastern chipmunks and often retreat to crevices.
4. Where are the best places to spot chipmunks in Missouri?
Eastern chipmunks thrive in mature forests with plenty of cover, such as Mark Twain National Forest, Hawn State Park, and the Ozark Trail. Look for them along stone walls, log piles, and under bird feeders in suburban yards. Least chipmunks are best sought in the Loess Hills of northwest Missouri, like Squaw Creek National Wildlife Refuge. For more state-specific tips, visit ourMissouri wildlife page.

5. When is the best time to see chipmunks in Missouri?
Chipmunks are diurnal and most active from April to October. In spring, they emerge from hibernation and are very visible foraging for food. Summer mornings and late afternoons are prime viewing times, especially after rain. During hot midday hours, they take shelter. They enter a torpor in winter but may come out on warm days. For a seasonal guide, see ourchipmunk activity calendar.
6. How can you tell the two chipmunks apart at a glance?
Focus on size, color, and stripe pattern. Eastern chipmunk: larger, brown with reddish rump, facial stripes more muted, tail bushy. Least chipmunk: smaller, grayer, facial stripes bold, tail slim. Also check the habitat: eastern chipmunks in forests, least chipmunks in rocky open areas. For a detailed comparison, refer to ourfield guide section.
