Squirrels in Michigan: Identification Guide and Where to Start Looking

1. What are the main squirrel species in Michigan?

Michigan has four squirrel species you're likely to see. The Eastern gray squirrel is the most common, with a gray body and white belly. Fox squirrels are larger with a reddish-brown back and orange belly. Red squirrels are smaller, rusty-colored, and often found in conifer forests. Southern flying squirrels are nocturnal and have a flap of skin between front and back legs. Each species has distinct vocalizations and habits. Gray squirrels make chattering calls and are highly vocal. Fox squirrels are quieter but more cautious. Red squirrels produce high-pitched chirps and alarm calls that carry far. Flying squirrels are mostly silent except for rare soft squeaks. Understanding these differences helps with field identification even before you see them clearly.

2. Where in Michigan are you most likely to see squirrels?

Anywhere with mature trees: city parks like Belle Isle in Detroit, suburban neighborhoods in Ann Arbor, and state forests like Huron-Manistee. Fox squirrels favor open woodlands and farm edges. Gray squirrels dominate in oak-hickory forests. Red squirrels stick to pine stands. Flying squirrels are rarely seen but live in mixed forests statewide. For more on squirrel habitats, visit ourMichigan wildlife hub. The Upper Peninsula supports red squirrels and flying squirrels at higher densities than the Lower Peninsula. Along Lake Michigan shorelines, gray squirrels thrive in beech and oak stands. In pine plantations of the north, red squirrels are predictable residents. Suburban feeders in southeastern Michigan attract gray and fox squirrels year-round.

3. What is the best season or time for squirrel sightings?

Squirrels are active year-round, but fall is prime: they gather walnuts and acorns. Early morning (sunrise to 9 a.m.) and late afternoon (4-6 p.m.) offer the best chances. In winter, look for tracks in snow near bird feeders. Summer litters of young are out by June. Flying squirrels are only seen an hour after dark. Spring brings increased vocal activity as males seek females. Autumn is the most active period overall, with heavy foraging. See ourstate animal guidefor the next step.

4. How can you tell a gray squirrel from a fox squirrel?

Size is the first clue: fox squirrels are noticeably chunkier (21-29 inches long) than grays (17-19 inches). Coloration: grays are mostly silver-gray with a white belly; fox squirrels have a rusty orange belly and often a brownish or blackish back. Tails: gray squirrel tail is flat and bushy with white edges; fox squirrel tail is rounded and more orange. Head shape also differs: gray squirrels have a smaller, more pointed face, while fox squirrels have a larger, blockier head. In profile, a fox squirrel's body appears heavier and more strong. When climbing, gray squirrels move faster and more acrobatically, while fox squirrels are more deliberate and powerful. Hearing their calls helps: gray squirrels produce rapid chatter, while fox squirrels are generally silent.

5. What do red squirrels look like and where do they live?

Red squirrels are about half the size of a gray squirrel (11-14 inches), with reddish fur on top, white belly, and a dark stripe along the side. They have a loud, chattering call. They prefer coniferous forests (pine, spruce, fir) in northern Michigan and the Upper Peninsula, but also live in mixed woods. Their active, quick movements help distinguish them. Red squirrels have distinctive ear tufts in winter that disappear in summer. Their tails are smaller and less bushy than gray or fox squirrels. In mixed forests, they defend territories fiercely and are often seen chasing rivals. They rely heavily on conifer seeds and often strip pine cones in large quantities, leaving debris on the ground.

6. How do you spot a southern flying squirrel?

It's tough because they're only active at night. They are small (9-11 inches), with grayish-brown fur, white belly, and large black eyes. The key identifier is the patagium (skin flap) that allows them to glide between trees. Listen for soft squeaks in wooded areas after dark. Use a flashlight to catch eye shine. They nest in tree cavities or bird boxes. Flying squirrels have proportionally larger eyes than other squirrels, adapted for low light. Their ears are hidden in fur, unlike red squirrels' prominent ear tufts. They often land high on tree trunks and run to the back side to hide. If you find an old woodpecker hole or tree cavity with glide marks around the entrance, flying squirrels may be nearby.

7. What are common squirrel lookalikes and how to avoid confusion?

Chipmunks are smaller with stripes on the face and back; they lack the bushy tail. Groundhogs are much larger and spend time on the ground, not in trees. The eastern fox squirrel and gray squirrel are often confused; focus on belly color and size. For more help with lookalikes, check oursquirrel identification page. Young gray squirrels can appear brownish and be mistaken for red squirrels, but red squirrels are always smaller and have ear tufts. Eastern chipmunks (Tamias striatus) have sharp facial stripes running through the eye and down the back, which no squirrel has. Woodchucks are terrestrial and rarely climb, while all Michigan squirrels are at least partly arboreal.

8. What tracks and signs indicate squirrel presence?

Fresh squirrel signs confirm they're in the area. Look for claw marks on bark, stripped pine cones piled on branches or ground, and nut shells split in half. Scat (droppings) is small, dark, and often found in clusters. Nests appear as large, leafy bulges high in trees, especially in oak and hickory. Fox squirrel nests are larger than gray squirrel nests. Snow in winter reveals tiny prints with four toes on front feet and five on back. Track patterns show the characteristic hopping trail of their movement. Bark stripping on young trees indicates damage, though not always from squirrels. Chewed acorns with rough edges rather than neat splits are often gray squirrel work.

10. Are black squirrels common in Michigan?

Black squirrels are a color morph of the Eastern gray squirrel, not a separate species. They are common in certain areas like Petoskey and Ann Arbor where the black allele became frequent in the population. The black coloration is recessive, so two gray parents can produce black offspring. In most of Michigan, black squirrels are uncommon or absent. They have the same size, behavior, and habitat preferences as gray squirrels. Some evidence suggests black morphs are slightly more susceptible to predation due to reduced camouflage in mixed woodlands.

11. Are squirrels active in winter, and how do they survive?

Yes, they do not hibernate. They rely on stored food caches and become less active on very cold days. Squirrels begin caching acorns and nuts in fall, often burying thousands but recovering only a fraction. Forgotten caches actually help regenerate oak forests. In winter, their metabolism slows slightly, but they remain active enough to move between caches and feeders. During extreme cold snaps, they stay in their nests for days. Their bushy tails serve as blankets and help with balance on icy branches.
