Other the squirrel family in Maine
Only one kind of chipmunk lives in Maine, so the useful question is which related animals share the state. 6 other members of the squirrel family have a verified record here, each with at least 10 confirmed sightings. The ones you are most likely to see, or mix up with a chipmunk, are American Red Squirrel, Eastern Chipmunk and Eastern Gray Squirrel. They are listed below, ranked by how often each is recorded.

When chipmunk are recorded in Maine
Maine is home to one main chipmunk species: the Eastern Chipmunk (Tamias striatus). If you're wondering what types of chipmunks live in Maine, the answer is straightforward, but you might also spot a few lookalikes like red squirrels. This guide covers field marks, timing, and the best spots to start your search.
1. How many chipmunk species live in Maine?
Maine has only one true chipmunk species: the Eastern Chipmunk (Tamias striatus). The Least Chipmunk, common in western states, does not occur in Maine. So when you see a small striped rodent scurrying through leaf litter in a Maine wood, you are almost certainly looking at an Eastern Chipmunk.
In Maine, 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 your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
2. What are the key field marks for identifying an Eastern Chipmunk?
Eastern Chipmunks are about 5-6 inches long (body) with a tail of 3-4 inches. They have five dark stripes running down their back, with lighter stripes in between. The center stripe runs all the way to the tail, and there are two light stripes above and below the eyes. Their cheeks are bulging when carrying food. The reddish-brown fur on the rump fades to gray on the sides.
3. Which animals in Maine are often mistaken for chipmunks?
The most common lookalike is the Red Squirrel, which is slightly larger, has a reddish coat with no facial stripes, and a bushy tail. Thirteen-lined Ground Squirrels look similar but have alternating rows of spots and stripes; they are rare in Maine and found mostly in the far southwest. Chipmunks move with a quick, darting run, while squirrels bound more.
4. Where in Maine are you most likely to spot chipmunks first?
Chipmunks are widespread across the state, but your best odds are in mixed hardwood forests, stone walls, and woodland edges. Start at any state park with oak or beech trees, such asBaxter State Parkor around Acadia. Suburban backyards with bird feeders also attract them. Check out ourchipmunk identification pagefor more tips.

5. What is the best season and time of day for chipmunk sightings?
Chipmunks are most active from April through October. They hibernate from November to March, but may emerge on warm winter days. The best time of day is early morning (around sunrise) and late afternoon (4-6 PM). In summer, they retreat during midday heat. Listen for their sharp "chip" calls, often a giveaway of nearby activity.
6. How can you distinguish chipmunk burrows from other animal holes?
Chipmunk burrows are typically 2 inches in diameter, often hidden under rocks, logs, or tree roots. Look for a clean, round hole with a small mound of excavated dirt. Unlike vole tunnels, chipmunk burrows have no runways. In fall, you may see chipmunks carrying mouthfuls of leaves down the hole, a sign they are stocking their winter chambers.
7. What should you bring on a chipmunk-spotting walk?
Binoculars help, but chipmunks are bold enough to observe from a few feet away. A field guide to mammals and a camera with a zoom lens are useful. Wear quiet shoes and move slowly. If you want to commemorate your sighting, consider aChipmunk T-Shirtor achipmunk stickerfrom Easy Street Markets.

8. How do chipmunks behave in different parts of Maine?
Chipmunks in northern Maine (e.g., Aroostook County) are less dense but occupy similar habitat. In southern coastal areas, they are abundant in parks and gardens. Chipmunks are solitary except during breeding in early spring and summer. They climb trees for nuts but spend most time on the ground. For more on regional habits, see ourMaine wildlife hub.
9. Frequently asked questions about Maine chipmunks
**Do chipmunks live in mountains?** Yes, they are found in the western mountains up to treeline. **Are chipmunks harmful to gardens?** They may dig up bulbs but rarely cause major damage. **Can you feed chipmunks?** It's best to watch without feeding, as human food disrupts their natural diet. **How long do chipmunks live?** Usually 2-3 years in the wild.
