Understanding Flying Squirrels
What are Flying Squirrels?
Flying squirrels are a group of nocturnal gliding mammals belonging to the family Sciuridae. They are not true flyers like bats but glide using a special membrane called the patagium.
Physical Characteristics
Flying squirrels have several distinctive features:
- Size: Varies by species, but they typically measure between 9 to 14 inches (23 to 36 cm) in length, including the tail.
- Coloration: Most have soft, brown or grey fur with lighter underparts.
- Body: Their bodies are compact and adapted for gliding, with large eyes for night vision.
- Patagium: A membrane of skin that stretches from their wrists to their ankles, allowing them to glide.
- Tail: Long and flattened, used for stability and steering during glides.
Gliding Abilities
Flying squirrels are capable of remarkable gliding feats:
- Distance: They can glide distances of up to 150 feet (46 meters) or more.
- Control: Use their tail and limbs to steer and control their descent, allowing for precise landings.
Habitat and Distribution
Global Distribution
Flying squirrels are found across various regions:
- North America: The Northern and Southern flying squirrels are common in North America.
- Asia: Several species, including the Japanese dwarf flying squirrel, are found in Asia.
