Are There Flying Squirrels in Connecticut?

Where Flying Squirrels Are Found in Connecticut

Flying squirrels occur throughout most of Connecticut, present in all regions of the state. Northern Connecticut forests, including areas near the Massachusetts border, support flying squirrel populations in hardwood stands. Central Connecticut's mixed deciduous forests harbor populations in both protected natural areas and private forests. Southern Connecticut and coastal regions maintain flying squirrel populations despite higher development pressure. Flying squirrels inhabit forests along the Connecticut River and Housatonic River valleys. They occupy woodlands near the Naugatuck River and other river systems across the state. State parks and forests including Devil's Den State Park and Sleeping Giant State Park support populations. Bluff Point and coastal forest preserves in Long Island Sound regions host flying squirrels despite proximity to human development. Flying squirrels prefer large cavity-bearing trees, particularly old oaks and hickories. Connecticut's location in southern New England means flying squirrels are at the northern edge of the southern flying squirrel's range. They require continuous or near-continuous forest canopy and cavity-bearing trees. Most forested areas throughout Connecticut provide suitable habitat for flying squirrels.

Season and Timing

Flying squirrels in Connecticut are active year-round despite cold winters and variable spring weather. Fall represents the most active season when flying squirrels spend long hours foraging and gathering nuts and seeds for winter caches. Acorns and hickory nuts become abundant in September and October, driving intensive gathering behavior. Winter activity continues as squirrels utilize cached food supplies stored throughout their territories. Spring brings breeding season activity as females prepare for reproduction. Early summer sees young flying squirrels emerging from nest cavities, increasing overall population movement. Summer nights provide active foraging as insects become abundant throughout Connecticut's forests. The relatively moderate Connecticut climate, influenced by proximity to the Atlantic Ocean, allows flying squirrels to remain active throughout winter despite occasional heavy snows. Autumn and early winter evenings are ideal for observing flying squirrel activity in forested areas. Spring transitions bring renewed activity as breeding begins. Throughout the year, mild nights encourage more activity than harsh conditions. Understanding Connecticut's seasonal patterns helps predict when flying squirrels are most likely to be observed.

How to Identify a Flying Squirrel

Flying squirrels are small, weighing only 2 to 3.5 ounces, much smaller than Connecticut tree squirrels. Their most distinctive feature is the gliding membrane, which stretches between front and hind legs. When at rest on trees, this membrane is invisible and hidden. Fur ranges from reddish-brown to grayish-brown on the back and white or cream-colored on the belly. Large, dark eyes adapted for night vision are positioned toward the front of the head, unlike tree squirrels with side-positioned eyes. Ears are small and rounded. Tails are bushy and slightly flattened, aiding balance and steering during glides. Adults measure about 8 to 10 inches from head to rear, with tails adding 7 to 9 inches. Southern flying squirrels make distinctive high-pitched chirps and chattering vocalizations. Clear identification requires nocturnal observation as they are strictly active after dark. Their small size and gliding ability distinguish them from Connecticut's tree squirrels. Seeing one clearly requires patience and night searching in appropriate forests with a flashlight.

Where Sightings Concentrate

Flying squirrel sightings in Connecticut concentrate in specific habitat types and regions. Devil's Den State Park in Weston supports populations in its extensive hardwood forests and supports public access for observation. Sleeping Giant State Park near Durham harbors flying squirrels in old-growth forest stands. Bluff Point in Groton offers coastal forest habitat supporting populations despite development pressure. Coastal forests along Long Island Sound in southern Connecticut maintain populations in mixed hardwood stands. Interior forests throughout central Connecticut, particularly in protected state forests and public lands, support populations. The Connecticut River floodplain forests support populations in riparian hardwood zones. Housatonic River valley forests harbor flying squirrels in appropriate habitat. Naugatuck River region forests support populations in various protection statuses. Private forested properties throughout Connecticut maintain populations where large cavity-bearing trees are protected. Areas with mature oak and hickory trees, particularly those with complex structure and abundant cavities, are most likely to host flying squirrels. Old-growth forest preserves and protected woodlots offer optimal habitat. State wildlife areas and natural preserves across Connecticut harbor populations accessible to interested observers. Nighttime exploration of mature hardwood forests offers the best chance of encountering flying squirrels.

Typical Behavior

Flying squirrels are strictly nocturnal, remaining hidden in tree cavity nests during daylight hours. At night, they emerge to forage through the canopy with remarkable agility and speed. Their gliding ability allows traversing large distances between trees silently and efficiently. Diet consists primarily of nuts, seeds, fungi, insects, and occasionally fruits and vegetation. Fall foraging focuses on gathering acorns and hickory nuts, storing them in multiple scattered caches throughout their home range. Females typically give birth to litters of two to four young in spring, born in cavity nests high in large trees. Young remain dependent for two to three months before dispersing in late summer and early fall. Flying squirrels are generally solitary except during breeding season and in winter when they sometimes share nests for warmth conservation. They communicate through vocalizations and scent marking. Home ranges typically span several acres with some overlap between individuals. During cold Connecticut winter nights, flying squirrels remain sheltered in their nests, relying on fall caches and stored energy. Communal nesting during winter helps conserve precious body heat. Young flying squirrels disperse in late summer, traveling through the forest seeking new territories away from maternal ranges.

Coexistence and Safety

Flying squirrels are completely harmless to humans and pose no threat to people or property. They are protected under Connecticut wildlife laws, making it illegal to trap or harm them without special permits. These nocturnal animals rarely interact with humans because they are active only at night and remain in forested areas. Residential areas with mature forest patches nearby may occasionally host flying squirrels. Having flying squirrels on your property indicates good forest habitat and ecosystem health. Flying squirrels do not cause property damage and do not enter buildings or create nuisance issues. They are not aggressive and actively avoid human contact. Flying squirrels play important ecological roles as seed dispersers and by consuming insects and fungi. Their presence indicates that cavity-bearing trees and forest structure remain intact. Wildlife managers recognize flying squirrels as valuable members of Connecticut's forest ecosystems. Protecting mature forests and maintaining cavity-bearing trees benefits flying squirrels and many other species. Education about flying squirrels builds public appreciation for Connecticut's nocturnal wildlife and forest ecosystems. ExploreConnecticut wildlifeto learn more about conservation.

Common Species Confusion

Flying squirrels could potentially be confused with other small mammals, though encounters are uncommon. Juvenile eastern gray squirrels are much smaller than adults but are active during daytime and lack the gliding membrane. Flying squirrels are strictly nocturnal while gray squirrels are diurnal. Fox squirrels are larger and active during daytime. The diagnostic feature of flying squirrels is their gliding membrane, visible when mid-glide or examined closely. Other Connecticut squirrels, such as red squirrels and ground squirrels, are ground-dwelling or daytime-active and lack gliding ability. Mice and rats are much smaller and lack the bushy tail and large eyes of flying squirrels. Shrews are small and lack the squirrel body plan. Opossums are active at night and climb trees but are much larger, lack gliding membranes, and have distinctive pointed faces. If you see a small, furry animal gliding silently between trees at night in a Connecticut forest, you have almost certainly seen a flying squirrel. Its combination of small size, nocturnal habits, and gliding ability make it distinctive. For more information about identifying Connecticut animals, visit theConnecticut wildlife guide.
