Are There Flying Squirrels in Indiana?

Where Flying Squirrels Are Found in Indiana

Flying squirrels inhabit the forested areas throughout Indiana, particularly in the southern and central regions. The Hoosier National Forest and Brown County State Park provide excellent habitat with mature hardwoods and mixed conifers. The Wabash River Valley supports thriving populations, as do the forests along the Patoka River in southwestern Indiana. Eastern deciduous forests dominate the state's wildlife habitat, creating ideal conditions for flying squirrels. You will find them in oak, maple, and hickory forests, and they are also present in smaller woodlots connected to larger forest blocks. The limestone hills and river valleys of southern Indiana, including areas near Kentuck Knob and the Brunwasser Ravine, are particularly favorable. Flying squirrels occupy forests from lowland river valleys to higher elevation woodlands throughout the state. For more on flying squirrel in Indiana, see ourIndiana flying squirrel guide.

Season and Timing for Indiana Flying Squirrels

Flying squirrels remain active year-round in Indiana, but their visibility changes with seasons. They are most active during spring and fall when they are preparing for seasonal changes and actively foraging. Winter months see reduced activity, but they do not hibernate and can be spotted on warmer nights. Breeding occurs twice yearly, with young appearing in spring and summer. Late evening and nighttime hours, particularly after sunset, offer the best viewing opportunities. During mild winter nights, flying squirrels venture out to search for seeds and nuts. Spring brings peak vocalization as males establish territories and locate mates. The quiet summer season reflects reduced movement, though gliders remain active when temperatures drop after sundown. Fall is an especially active period as squirrels collect and cache food for winter months. You can also browseIndiana wildlife.

How to Identify Flying Squirrels

Flying squirrels are small, delicate rodents, weighing only two to three ounces and measuring seven to nine inches in body length. They have large forward-facing eyes adapted for low light, giving them excellent night vision. The most distinctive feature is the patagium, a furry membrane stretching between front and hind legs that enables gliding. Their fur is soft and gray above with white undersides, and males are slightly smaller than females. Flying squirrels have large, fluffy tails that serve as rudders during gliding and provide insulation when wrapped around them during rest. Their ears are small, rounded, and partly hidden in fur. Compared to eastern gray squirrels, flying squirrels appear distinctly delicate, with finer facial features and larger eyes. They make high-pitched chirping sounds, especially when alarmed or during mating season. Their most recognizable behavior is their ability to launch from trees and glide smoothly between perches, though this requires observing them at night. See all of ourwildlife guides.

Where Sightings Concentrate in Indiana

Within Indiana, flying squirrel sightings concentrate in areas with mature forest cover and suitable den trees. The corridors along the Wabash River and its tributaries support consistent populations where raccoons and owls also thrive. Brown County and nearby Morgan Monroe State Forest represent prime viewing locations, with dense oak and hickory stands. Old growth forests with large cavities in sycamore, tulip poplar, and oak trees attract nesting squirrels. Suburban woodlots connected to forest patches increasingly support flying squirrel colonies, especially where homeowners provide nest boxes. The bottomland forests along the Ohio River in southern Indiana concentrate populations, particularly in Harrison and Crawford counties. State parks with mature woodland restoration efforts, such as Maumee Bay and Muscatatuck National Wildlife Refuge, show increased flying squirrel presence. Urban and suburban gardens with mature oak trees sometimes attract foraging individuals. Focus searches along forest edges at dusk to maximize encounter chances.

Typical Behavior and Habits

Flying squirrels are strictly nocturnal, spending daylight hours in tree cavities or outside nests made of leaves and twigs. They are highly social compared to most squirrels and often nest communally, with multiple individuals sharing a den during winter months. Their diet consists primarily of nuts, seeds, fungi, and acorns, with oak mast years triggering population increases. Flying squirrels consume hazelnuts, hickory nuts, and pine seeds with equal enthusiasm. Insects provide protein during warmer months, supplementing their primarily vegetarian diet. They make distinctive vocalizations including chirps, clicks, and ultrasonic calls used for communication. Gliding represents their primary mode of travel between trees, allowing rapid escape from predators and efficient foraging across forest canopies. They do not truly fly but rather controlled glide, using their tail for balance and directional control. Scent marking and territorial behavior intensify during breeding seasons. In Indiana's wildlife area, flying squirrels are important prey for barn owls, screech owls, and foxes.

Coexistence and Legal Protections

Flying squirrels hold no special legal protection in Indiana and are not hunted or trapped. Their small size and nocturnal habits mean direct conflicts with humans are rare. No poisoning or removal is necessary in residential areas, and they pose no threat to homes or property. Flying squirrels rarely compete with humans for resources and actually help forest health by dispersing fungi and seeds. In residential settings, if a flying squirrel enters an attic, simple, humane exclusion using one-way doors allows safe departure. Providing dead trees and maintaining forest connectivity supports stable populations. Flying squirrels are indicators of healthy forest ecosystems and their presence signifies good woodland management. Homeowners interested in supporting flying squirrels can install nest boxes designed specifically for their small size. Indiana's wildlife management practices recognize flying squirrels as beneficial forest inhabitants. Their presence enriches local ecosystems and provides educational opportunities for residents interested in nocturnal wildlife.

Common Species People Mistake for Flying Squirrels

Eastern gray squirrels are the most commonly confused species with flying squirrels, despite significant size differences. Gray squirrels weigh three times more, measure seventeen inches in length, and are active during daylight. Young gray squirrels are more slender but lack the characteristic patagium and large eyes of flying squirrels. The eastern fox squirrel, Indiana's largest squirrel species, is occasionally mistaken for a flying squirrel due to color variation, but it is twice the size of a flying squirrel. Red squirrels are smaller and more reddish in color but still lack the patagium and large forward-facing eyes. At night, some people confuse flying squirrels with small bats, particularly when seeing the silhouette of their gliding patagium. However, bats fly with rapid wing beats, while flying squirrels glide in smooth arcs. Possums are sometimes misidentified as flying squirrels in suburban areas, though they are much larger and have hairless tails. Accurate identification requires noting the large eyes, soft gray fur, patagium, and distinctive gliding behavior of flying squirrels.

Frequently Asked Questions

Q: Can I see flying squirrels in my Indiana backyard? A: Yes, if your property borders a forest with mature trees. Flying squirrels visit yards with oak trees and brush piles, especially at night when your eyes cannot detect them well. Using infrared cameras or spotlights after dark increases sighting chances.

Q: How do flying squirrels glide without wings? A: A furry membrane called the patagium stretches between their front and hind legs. When they jump from high branches, they spread their legs wide, stretching this membrane like a parachute, allowing them to glide smoothly downward at a controlled angle.

Q: What sounds do flying squirrels make? A: They produce high-pitched chirps, clicks, and ultrasonic calls inaudible to human ears. During mating season, males vocalize extensively to establish territories and attract females.

Q: Are flying squirrels endangered in Indiana? A: No, flying squirrels remain stable in Indiana's forests. Visit/wildlife/indianafor more state wildlife information, or explore/wildlifefor guides to other Indiana species. Check/wildlife/indiana/flying-squirrelfor additional details.
