Do Flying Squirrels Walk? Dispelling the Myth of Perpetual Flight
Yes, flying squirrels do walk. While known for their gliding abilities, they are also adept at terrestrial locomotion and frequently utilize walking and running as their primary means of navigating across branches and the ground.
The Terrestrial Life of Gliding Mammals
While their name suggests an exclusively aerial existence, the reality of a flying squirrel’s life is far more grounded. These fascinating creatures spend a significant portion of their time not soaring through the air, but instead, scurrying along branches, climbing tree trunks, and even occasionally venturing onto the forest floor. To truly understand the answer to the question, Do flying squirrels walk?, we need to appreciate the full spectrum of their behaviors.

Anatomy Built for Both Air and Ground
Flying squirrels possess a unique anatomy that allows them to excel in both arboreal and gliding environments. Their defining feature is the patagium, a furry membrane that extends from wrist to ankle, enabling them to glide. However, their limbs and claws are equally important for their lives on foot:
- Strong claws: Provide excellent grip for climbing and navigating uneven surfaces.
- Flexible joints: Allow for a wide range of motion, essential for maneuvering through complex tree structures.
- Prehensile tail: While primarily used for steering during glides, it also offers balance and support while walking.
This combination of adaptations proves that flying squirrels are not solely dependent on gliding. The structure of their bodies reflects the importance of both flying and walking to their survival.
The Purpose of Walking
Walking serves several crucial purposes for flying squirrels:
- Foraging: While they can glide between food sources, walking is often more efficient for searching within a specific area.
- Navigation: In dense forests, walking allows for more precise navigation around obstacles than gliding.
- Social interaction: Walking is used during social interactions, such as mating displays and territory defense.
- Ground travel: Although they prefer to stay in trees, flying squirrels will occasionally venture onto the ground to access resources or cross short distances. This ground travel is almost entirely done by walking or running.
Gliding vs. Walking: Efficiency and Energy Expenditure
The choice between gliding and walking for a flying squirrel often comes down to efficiency and energy expenditure. While gliding allows them to cover long distances quickly, it requires a clear path and a suitable launching point. Walking, on the other hand, is more versatile and allows them to navigate complex environments. It requires less energy than launching into a glide, especially for short distances.
| Feature | Gliding | Walking |
|---|---|---|
| —————– | ——————————— | ———————————– |
| Distance | Long distances efficiently | Short to moderate distances |
| Obstacles | Requires clear path | Navigates around obstacles easily |
| Energy Use | High initial energy for launch | Lower energy expenditure overall |
| Maneuverability | Limited during the glide | High maneuverability |
Common Misconceptions
A common misconception is that flying squirrels only glide. This belief stems from their distinctive anatomy and the captivating nature of their aerial abilities. However, observing their behavior in their natural habitat quickly dispels this myth. Understanding that flying squirrels do walk requires recognizing their adaptations for both aerial and terrestrial environments.
Observing Walking Behavior
Evidence of flying squirrels walking is readily available through direct observation and camera trapping. Scientists and nature enthusiasts alike have documented countless instances of flying squirrels walking on branches, tree trunks, and even the ground. These observations provide irrefutable proof that walking is an integral part of their behavior.
Environmental Factors Influencing Locomotion
Environmental factors play a significant role in determining whether a flying squirrel will choose to walk or glide.
- Forest Density: Denser forests with numerous obstacles make walking more practical.
- Weather Conditions: High winds or heavy rain may discourage gliding.
- Predator Presence: Ground predators might encourage staying in the trees and utilizing walking.
- Resource Availability: Proximity of food resources can influence the choice between walking and gliding.
Frequently Asked Questions
Are flying squirrels really squirrels?
Yes, flying squirrels are indeed members of the squirrel family (Sciuridae). They belong to a specific group called the Pteromyini or flying squirrels, which are characterized by their gliding membrane. This makes them true squirrels with a unique adaptation.
How do flying squirrels walk on branches?
Flying squirrels walk on branches using their sharp claws to grip the bark and their prehensile tail for balance. Their flexible joints also enable them to navigate uneven surfaces effectively. They move with agility and precision, rarely falling.
Do flying squirrels walk on the ground?
Yes, flying squirrels do walk on the ground, although they prefer to stay in trees. They will venture onto the ground to access resources, cross short distances, or explore new areas. This ground travel is usually a quick and deliberate movement.
Are there different species of flying squirrels?
Yes, there are many different species of flying squirrels found throughout the world. These species vary in size, color, and habitat preferences, but they all share the characteristic gliding membrane. Common examples include the Northern Flying Squirrel and the Southern Flying Squirrel in North America.
How far can a flying squirrel glide?
The distance a flying squirrel can glide varies depending on the species, but some individuals can glide up to 300 feet or more. Wind conditions, launch height, and the presence of obstacles all influence the gliding distance.
What do flying squirrels eat?
Flying squirrels have a varied diet that includes nuts, seeds, fruits, fungi, insects, and occasionally bird eggs. Their diet depends on the availability of resources in their habitat and varies seasonally.
How do flying squirrels steer while gliding?
Flying squirrels steer while gliding by adjusting the tension of their patagium and using their tail as a rudder. These adjustments allow them to change direction mid-air and navigate to their desired landing spot.
Are flying squirrels nocturnal?
Yes, flying squirrels are primarily nocturnal animals, meaning they are most active at night. They spend the day sleeping in tree cavities or nests and emerge at night to forage and interact with others.
Where do flying squirrels live?
Flying squirrels live in forested areas across North America, Europe, and Asia. They prefer habitats with mature trees that provide cavities for nesting and an abundance of food resources.
Are flying squirrels endangered?
While some species of flying squirrels are threatened or endangered, most are not currently considered to be at risk. Habitat loss and fragmentation are the primary threats to their populations. However, the question of Do flying squirrels walk? is unrelated to whether they are endangered.
How can I attract flying squirrels to my backyard?
You can attract flying squirrels to your backyard by providing suitable habitat, such as nest boxes and a variety of trees and shrubs that offer food and shelter. Avoid using pesticides or other chemicals that could harm them.
Why are flying squirrels called “flying” squirrels if they don’t really fly?
Flying squirrels are called “flying” squirrels because they glide, not fly. Their gliding membrane allows them to soar through the air, giving the impression of flight. This behavior distinguishes them from other types of squirrels that can only climb and run. The name stuck, even though flying squirrels do walk just as much, or even more, than they glide.
