1. Discovering Pennsylvania’s Gliding Wonders: Flying Squirrels
Do flying squirrels live in Pennsylvania? Absolutely, Pennsylvania hosts two types of flying squirrels: the Northern Flying Squirrel and the Southern Flying Squirrel. Let’s delve into their distinctive traits, habitats, and conservation status to appreciate these gliding mammals truly.
1.1. What Exactly Is a Flying Squirrel?
What are flying squirrels? Flying squirrels, contrary to their name, don’t actually fly; instead, they glide using a membrane called a patagium that stretches between their wrists and ankles. This membrane allows them to soar from tree to tree with incredible agility.
- Patagium: This unique skin flap acts like a glider, enabling the squirrel to navigate effortlessly through the forest canopy.
- Nocturnal Habits: Active primarily at night, their large eyes are adapted to low-light conditions, making them elusive to daytime observers.
- Arboreal Lifestyle: They spend most of their lives in trees, building nests in tree cavities or constructing dreys (leaf nests).
1.2. Northern Flying Squirrel (Glaucomys sabrinus)
What is a Northern Flying Squirrel? The Northern Flying Squirrel is one of the two flying squirrel species found in Pennsylvania. It thrives in older-growth forests and plays a vital role in the ecosystem.
- Appearance: Slightly larger than its southern counterpart, the Northern Flying Squirrel boasts a body length of 8 to 11 inches.
- Habitat: It prefers old-growth spruce and conifer stands with plenty of downed woody debris on the forest floor.
- Diet: Their diet mainly includes fungi, lichens, acorns, and conifer seeds, all crucial for their survival.
- Reproduction: Typically, they have one litter per year, born in mid to late May, with one to four young per litter.
- Conservation Status: Due to habitat loss, the Northern Flying Squirrel is listed as a species of concern in Pennsylvania, requiring ongoing conservation efforts.
1.3. Southern Flying Squirrel (Glaucomys volans)
What is a Southern Flying Squirrel? The Southern Flying Squirrel is the second species found in Pennsylvania. It’s smaller and more adaptable, often found in various forest types.
- Appearance: Slightly smaller, ranging from 8 to 10 inches in body length. The key difference is the color of their belly hair.
- Habitat: They are more adaptable than Northern Flying Squirrels, inhabiting deciduous and mixed forests.
- Diet: Similar to the Northern species, their diet includes nuts, seeds, fruits, and insects.
- Reproduction: They can have multiple litters per year, making their populations more resilient.
- Conservation Status: The Southern Flying Squirrel is more common and not considered a species of concern.
1.4. Distinguishing Between the Two Species
How can you tell the difference between Northern and Southern Flying Squirrels? While both species share similar appearances, a close look reveals key differences:
| Feature | Northern Flying Squirrel | Southern Flying Squirrel |
|---|---|---|
| Size | 8-11 inches | 8-10 inches |
| Habitat | Old-growth conifer forests | Deciduous and mixed forests |
| Belly Hair Color | Darker base fading to white at the tip | White from tip to base |
| Range | Primarily northern Pennsylvania | More widespread throughout the state |
1.5. Ecological Role of Flying Squirrels
What role do flying squirrels play in the ecosystem? Flying squirrels contribute significantly to forest health by:
- Seed Dispersal: As they forage for food, they help spread seeds, promoting forest regeneration.
- Fungal Dispersal: Their consumption of fungi aids in spore dispersal, essential for the health of mycorrhizal networks that support tree growth.
- Prey Species: They serve as a food source for various predators, including owls, foxes, and snakes, maintaining balance in the food web.
2. Prime Habitats of Pennsylvania’s Flying Squirrels
Where do flying squirrels live in Pennsylvania? The ideal habitat for Northern Flying Squirrels includes old-growth forests with spruce and conifer trees, while Southern Flying Squirrels are more versatile and can be found in diverse forest environments.
2.1. Ideal Conditions for Northern Flying Squirrels
What makes a forest suitable for Northern Flying Squirrels? These squirrels thrive in:

- Coniferous Trees: Spruce and fir trees provide essential food sources like seeds and fungi.
- Downed Woody Debris: Fallen logs and branches create microhabitats for fungi, a primary food source.
- Tree Cavities: Natural cavities and abandoned woodpecker holes serve as den sites for nesting and shelter.
2.2. Adaptable Habitats of Southern Flying Squirrels
Where can Southern Flying Squirrels survive? Southern Flying Squirrels are more adaptable, living in:
- Deciduous Forests: These forests provide a variety of nuts, seeds, and fruits for their diet.
- Mixed Forests: A combination of coniferous and deciduous trees offers diverse food and shelter options.
- Urban Areas: They can even adapt to suburban and urban environments with enough tree cover.
2.3. Geographical Distribution in Pennsylvania
Where are these squirrels located in Pennsylvania?
- Northern Flying Squirrel: Primarily found in the northern, especially northeastern, regions of Pennsylvania, where old-growth coniferous forests persist.
- Southern Flying Squirrel: More widespread throughout the state, including southern and central regions, due to their adaptability.
2.4. Impact of Habitat Fragmentation
How does habitat fragmentation affect flying squirrels? Fragmentation poses significant threats:
- Reduced Connectivity: Isolated forest patches limit their ability to glide and forage, reducing genetic diversity and increasing vulnerability to local extinctions.
- Increased Predation: Smaller habitat patches offer less cover, making them more susceptible to predators.
- Limited Resources: Fragmented forests may lack the food and nesting resources needed to support healthy populations.
3. The Endangered Status of the Northern Flying Squirrel
Why is the Northern Flying Squirrel endangered in Pennsylvania? The Northern Flying Squirrel faces numerous threats, including habitat loss, competition, and climate change, leading to its endangered status.
3.1. Historical Logging Practices

- Population Extinction: Local extinctions in many areas.
3.2. Competition with Southern Species
Why are Southern Flying Squirrels a threat to Northerns? The expansion of Southern Flying Squirrels into Northern habitats poses a competitive challenge:
- Resource Competition: Southern Flying Squirrels compete for food and nesting sites, often outcompeting the Northerns.
- Adaptability: Southern Flying Squirrels are more adaptable to different forest types, giving them an advantage.
3.3. Climate Change Impacts
How does climate change affect flying squirrels? Climate change exacerbates existing threats:
- Habitat Shifts: Warmer temperatures allow southern tree species to move north, altering forest composition and reducing habitat for Northern Flying Squirrels.
- Increased Stress: Climate-related stressors can weaken their immune systems, making them more susceptible to diseases.
