Michigan is home to a diverse array of squirrel species, each with unique behaviors, habitats, and appearances. Whether you’re a wildlife enthusiast, a homeowner dealing with a squirrel invasion, or simply curious about local wildlife, understanding the different types of squirrels in Michigan can enhance your appreciation and aid in identification.
The Eastern Gray Squirrel (Sciurus carolinensis) is perhaps the most common squirrel in Michigan. Recognizable by its predominantly gray fur and white belly, this species is highly adaptable to urban, suburban, and forested environments. They are excellent climbers, often seen darting through tree canopies, and are known for their bushy tails and playful behavior. Their ability to thrive in diverse habitats makes them a familiar sight across the state.
The Fox Squirrel (Sciurus niger) is the largest squirrel in Michigan, distinguished by its striking reddish-orange fur and large size. Typically found in open woodlands and edges, they prefer areas with tall trees and ample ground cover. Fox squirrels are more terrestrial than gray squirrels, often seen foraging on the ground for nuts, seeds, and sometimes insects. Their impressive size and vibrant color make them a standout among Michigan’s squirrel species.
The Red Squirrel (Tamiasciurus hudsonicus) is smaller and more aggressive than its gray and fox counterparts. Known for its bright reddish fur and distinctive white eye ring, this squirrel is most active in coniferous forests and pine woods. They are vocal, often chattering loudly to defend their territory, and are known for collecting and storing pine cones. Their energetic nature and preference for conifer habitats make them a key species in Michigan’s forest ecosystems.
The Southern Flying Squirrel (Glaucomys volans) is a nocturnal species that glides between trees using a flap of loose skin called a patagium. Though less commonly seen, they inhabit mature hardwood and mixed forests in Michigan. Recognizable by their soft, grayish fur and large, dark eyes, these squirrels are fascinating for their ability to glide distances of up to 150 feet. They primarily feed on nuts, seeds, and fungi, playing a vital role in forest ecology.
The Northern Flying Squirrel (Glaucomys sabrinus) is similar in behavior to the southern species but tends to prefer cooler, more boreal forests. Slightly larger and with a more subdued gray-brown coloration, they are also nocturnal gliders. Their presence indicates healthy, mature forests with plenty of canopy cover. Like their southern relatives, they feed on nuts, fungi, and lichens, contributing to forest seed dispersal and nutrient cycling.
While technically not a squirrel, the Eastern Chipmunk (Tamias striatus) is often grouped with tree squirrels due to its similar habits. Recognizable by its striped back and chubby cheeks, it is common in residential areas, parks, and forests. Chipmunks are ground dwellers that store food in their cheek pouches for winter. Their burrowing behavior and frequent foraging make them an essential part of Michigan’s small mammal community.
The Woodland Ground Squirrel (Spermophilus tridecemlineatus), or thirteen-lined ground squirrel, is found in open grasslands and prairies in Michigan’s southern regions. Notable for its distinctive striped pattern on the back, it spends most of its time on the ground digging burrows. These squirrels hibernate during the winter and are primarily herbivorous, feeding on seeds, grasses, and insects. Their unique appearance and ground-based lifestyle set them apart from arboreal species.
When selecting a squirrel to observe or manage, consider habitat, size, coloration, and behavior. For example, if you see a large, reddish squirrel near open woodlands, it’s likely a fox squirrel. Gray squirrels are more adaptable and found in urban and wooded areas alike. Flying squirrels require night-time observation or tree cavity sightings, while chipmunks are ground dwellers with prominent cheek pouches. Understanding these traits helps in accurate identification and appropriate interaction.
