Whether you’re a wildlife enthusiast, a homeowner concerned about bats in your attic, or simply curious about the diverse bat species in Minnesota, understanding the different types of bats that inhabit the state is essential. This listicle explores the most common and notable bat species found across Minnesota, highlighting their unique traits, habitats, and roles in the ecosystem. Dive in to learn about these fascinating creatures and how to identify them.
Big Brown Bat (Eptesicus fuscus)
The Big Brown Bat is one of Minnesota’s most widespread and easily recognizable species. They are robust, with a wingspan of about 13-15 inches, and have a rich, dark brown fur that gives them their name. Big Browns are excellent insect hunters, primarily feeding on beetles and moths, making them beneficial for natural pest control. They often roost in buildings, tree cavities, and under bridges, and are known for their adaptability to urban environments.
The Eastern Red Bat sports striking bright red or orange fur, which makes it stand out among Minnesota’s bat species. They are medium-sized, with a wingspan of approximately 11-13 inches, and are solitary roosters, often found roosting on tree branches during the day. Red Bats primarily feed on moths and flies, and their vibrant coloration helps them blend into autumn foliage, aiding in camouflage from predators.
The Silver-haired Bat is notable for its long, silky silver-gray fur that covers its entire body, giving it a distinctive appearance. They are medium-sized, with a wingspan of about 10-11 inches, and prefer forested areas and riparian zones for roosting. Silver-haired Bats are insectivorous, feeding mainly on moths and beetles, and are known for their late migration and active summer months in Minnesota.
The Little Brown Bat is perhaps the most common bat in Minnesota, often found roosting in buildings, caves, and tree hollows. They are small, with a wingspan of 8-11 inches, and have a uniform brown fur that darkens with age. These bats are highly beneficial, consuming large quantities of agricultural pests like moths, beetles, and flies, and are crucial for natural pest management in the region.
The Northern Long-Eared Bat is distinguished by its long, thin ears that extend beyond its face and its brown fur, which is slightly darker than other Myotis species. They prefer mature forests and roost in tree cavities or under bark. They feed on moths, flies, and beetles, and have faced significant threats from white-nose syndrome, leading to conservation concerns in Minnesota.
The Hoary Bat is the largest bat species in Minnesota, easily identified by its thick, frosted-gray fur tipped with black, giving it a hoary appearance. They are solitary and tend to roost in tall trees, especially during migration. Hoary Bats primarily feed on moths and are known for their impressive long-distance migrations, traveling from northern breeding grounds to southern wintering sites.
This small bat is notable for its tiny feet and dark, reddish-brown fur. It prefers rocky habitats, such as cliffs and caves, where it roosts in crevices. Despite its small size, it is an effective insectivore, feeding on moths and beetles, and is considered a species of concern due to habitat loss and white-nose syndrome.
The Tricolored Bat, formerly known as the Eastern Pipistrelle, has a distinctive tri-colored fur pattern—reddish at the base, yellowish in the middle, and darker at the tips. They are small, with a wingspan of about 8-9 inches, and often roost in tree cavities, buildings, and bat boxes. Tricolored Bats feed on moths and flies and are sensitive to white-nose syndrome, making monitoring vital.
When selecting or identifying bats in Minnesota, consider factors such as size, fur color, habitat preference, and roosting behavior. Recognizing the differences between species like the Big Brown Bat’s robust build and the Silver-haired Bat’s distinctive fur can aid identification. Additionally, understanding their preferred environments—whether they roost in trees, buildings, or caves—helps in locating and protecting these bats. Always prioritize safety and conservation when observing or managing bats, especially given concerns like white-nose syndrome affecting many species.
