You might spot a flying squirrel anywhere there’s a big patch of woods, especially if you see old trees and hollow spots around. Try looking for them at night along the edges of forests, in parks with mature trees, or near old snags where they like to nest.
If you live in the eastern US, chances are southern flying squirrels live nearby. In northern or higher-elevation forests, the northern species is probably closer.
Let’s talk about how you can narrow down the best spot, what signs to keep an eye out for, and which species you might actually see.
Start by checking out local forests, big yards with old trees, or even local parks after dark. Quiet, leafy areas give you the best shot at spotting their gliding moves or hearing those high-pitched calls.
Finding the Closest Flying Squirrel
If you want to find flying squirrels, you’ll need to know where they hang out, what kind of habitat they like, and how they act at night. Look for spots with mature trees, nest cavities, and a good mix of food sources—your odds go way up.
Range and Distribution of Flying Squirrels
In North America, two main species show up in most places: the southern flying squirrel (Glaucomys volans) and the northern flying squirrel (Glaucomys sabrinus).
Southern flying squirrels live all over the eastern U.S., from Maine to Florida and west toward Texas and Minnesota. Northern flying squirrels pop up in cooler forests in the Northeast, along the Pacific Coast, and in higher inland elevations.
Some smaller regional species, like Humboldt’s flying squirrel on the West Coast, also show up in local surveys. Park maps and state wildlife websites can tell you which Glaucomys lives nearby.
If you live near mixed deciduous or coniferous forests, you’re probably inside the range of at least one species.
Best Habitats to Search Nearby
Look for mature forests with big trees, snags, and old woodpecker holes. Flying squirrels love nesting in cavities, abandoned dreys, or even nest boxes.
They seem to prefer forests with oaks, hickories, or beeches (that’s for southern Glaucomys), and areas with some conifer or mixed forest work better for northern types.
Try wooded trails, riparian strips, and forest edges where trees grow tall and close together. Nighttime canopy cover matters—a thick canopy gives them safe gliding routes.
If you want to attract them, put a nest box on a tree about 10–30 feet high. Trail cameras pointed at box entrances or a fruiting fungus patch often catch them in action.
Tips for Spotting Flying Squirrels in the Wild
Head out at dusk or in the first few hours after dark. Flying squirrels stick to the night and get most active on calm, moonlit evenings.
Use a red-filtered flashlight to spot their eye shine without scaring them off.
Set a trail camera about 10–20 feet up, aiming at a cavity, nest box, or a fruiting log. You can bait with peanut butter, suet, or chopped nuts, but don’t feed them regularly—no need to mess with their natural habits.
Listen for soft chattering and scratching in leaf litter or hollow trees. A sound recorder helps during breeding season.
Move quietly, wear neutral clothes, and if you can, climb to a higher spot to watch their glide paths between tall trees.
Flying Squirrel Species and Adaptations
Let’s get into which two North American flying squirrels you might run into, what lets them glide, and where they like to make their homes.
You’ll find details on their size, what they eat, how their bodies work for gliding, and the kind of places they use for dens.
Northern Flying Squirrel vs. Southern Flying Squirrel
You can tell these two apart by size, belly color, and what they like to eat. The northern flying squirrel (Glaucomys sabrinus) is bigger and usually has a grayish belly.
The southern flying squirrel (Glaucomys volans) is smaller with a pure white belly. Both belong to the squirrel family Sciuridae and only come out at night.
Northern flying squirrels eat more fungi and truffles, while southerns go for insects, eggs, and little critters a bit more often.
Range plays a big role. Northerns live in boreal and mixed forests across Canada and the northern U.S. Southerns stick to deciduous forests further south, but sometimes their ranges overlap.
If you check attics or nest boxes in mixed-wood forests, you could find either species, depending on where you live.
Unique Physical Features and Gliding Ability
A furry membrane called the patagium stretches from wrist to ankle and forms the gliding surface. When a flying squirrel spreads its limbs, that patagium turns its body into a kind of wing, letting it glide at 20–30 mph and steer with its tail.
Their big eyes help you spot them at night—they gather up more light so the squirrels can zip between trees.
They’ve got long whiskers for sensing obstacles, a flat tail for steering and braking, and thick fur to keep warm. Flying squirrels can’t really fly like birds or bats, but their gliding tricks let them cross big gaps and stay off the ground, away from predators.
Preferred Nesting Sites and Behaviors
You’ll usually spot flying squirrels hanging out in tree cavities, old woodpecker holes, or even nest boxes. They really like big trees and snags with loose bark—those spots just seem perfect for them.
In mature forests, you might notice several squirrels, or even whole families, sharing a den. Sometimes, these social dens can pack in anywhere from 6 to 30 squirrels. That’s a lot of company!
Habitat loss changes how they pick their nests. When old-growth trees vanish, flying squirrels might sneak into attics or use human-made nest boxes instead.
If you’d rather keep them living wild, try putting up a cavity box or just leave dead trees standing, as long as it’s safe.
