1. What Exactly Is A Flying Squirrel?
A flying squirrel is not a true flying animal like a bird or bat, but rather a gliding mammal. It’s a type of squirrel belonging to the tribe Pteromyini within the Sciuridae family, characterized by a membrane of skin that extends between their front and hind legs, enabling them to glide from tree to tree.
To better understand what constitutes a flying squirrel, let’s delve into its key characteristics:
- Gliding Membrane (Patagium): This is the most defining feature. The patagium is a furry membrane stretching from the wrists to the ankles, acting like a wing during gliding.
- Flattened Tail: The tail is broad and flat, serving as a rudder for steering and a brake for landing.
- Size and Appearance: They are generally smaller than other tree squirrels, with soft, dense fur, large eyes for nocturnal vision, and a relatively flat body.
- Nocturnal Behavior: Flying squirrels are primarily nocturnal, meaning they are most active at night.
- Habitat: They inhabit wooded areas, preferring forests with a mix of tree species for food and nesting.
- Diet: Flying squirrels are omnivorous, eating a variety of nuts, seeds, fruits, fungi, insects, and sometimes eggs or nestlings.
1.1. What Distinguishes Flying Squirrels From Other Squirrels?
The primary difference is, of course, their ability to glide using the patagium. Other differences include:
- Activity Pattern: Most tree squirrels are diurnal (active during the day), while flying squirrels are nocturnal.
- Social Behavior: Some species of flying squirrels are more social than other squirrels and may nest communally, especially during the winter.
- Dietary Habits: While both eat similar foods, flying squirrels may rely more on fungi and insects.
1.2. Are Flying Squirrels Rodents?
Yes, flying squirrels are classified as rodents. They belong to the order Rodentia, which is characterized by having continuously growing incisors used for gnawing.
2. What Are The Different Species Of Flying Squirrels?
There are around 50 species of flying squirrels found worldwide. However, only three species are native to North America:
- Northern Flying Squirrel (Glaucomys sabrinus): Found in Canada, Alaska, and parts of the northern United States, as well as along the Appalachian and Rocky Mountains.
- Southern Flying Squirrel (Glaucomys volans): Found in the eastern United States, from southern Canada to Florida and west to the Great Plains.
- Humboldt’s Flying Squirrel (Glaucomys oregonensis): Found in the Pacific Northwest region of North America.
2.1. How Can You Differentiate Between The Northern And Southern Flying Squirrel?
Distinguishing between the Northern and Southern flying squirrels can be tricky, but there are a few key differences:
| Feature | Northern Flying Squirrel (Glaucomys sabrinus) | Southern Flying Squirrel (Glaucomys volans) |
|---|---|---|

3. How Do Flying Squirrels “Fly”?
Flying squirrels don’t truly fly; they glide. They use a membrane called the patagium to extend their body surface area, allowing them to soar between trees.
Here’s a step-by-step breakdown of their gliding technique:
- Launch: The squirrel leaps from a high point, such as a tree branch.
- Extension: It extends its limbs, stretching the patagium into a wing-like surface.
- Glide: As it glides, the squirrel can control its direction and angle by adjusting the tension and position of its patagium and tail.
- Landing: To land, the squirrel pulls up its tail, using it as a brake, and maneuvers itself to land vertically on a tree trunk.
3.1. How Far Can A Flying Squirrel Glide?
Flying squirrels can glide impressive distances. The average glide is around 20 to 30 feet, but they can cover distances of up to 150 feet or more in a single glide.
3.2. How Do They Control Their Glides?
They use their tail as a rudder to steer and control their direction. They also adjust the tension of the patagium to change their glide angle and speed.
3.3. What Are The Physics Behind Their Gliding Ability?
The physics behind flying squirrel gliding involves several principles:
- Lift: The patagium creates lift as air flows over its surface, similar to how an airplane wing works.
- Drag: The patagium also creates drag, which slows the squirrel down and helps it control its descent.
- Gravity: Gravity is the force pulling the squirrel downward.
- Control Surfaces: The tail acts as a control surface, allowing the squirrel to steer and adjust its glide.
4. Where Do Flying Squirrels Live?
