How do Sugar Gliders Fly Without Wings
Sugar gliders don’t actually “fly” like birds or bats; instead, they glide using a unique membrane called the patagium, which extends from their wrists to their ankles. This gliding ability allows them to travel impressive distances between trees, up to about 150 feet (45 meters). Here’s how they do it:
- Launching Off: To glide, a sugar glider will leap off from a high point, like a tree branch. Before jumping, it spreads its limbs outward, extending the patagium to create a surface area for catching air.
- Stretching the Patagium: When they leap, they spread their legs apart, creating a broad, parachute-like structure with the patagium. This membrane slows their descent and helps them glide smoothly, with the patagium acting like wings on a plane to support their body weight in the air.
- Controlling Direction: They use small adjustments with their limbs to steer while gliding, controlling their direction and angle of descent. Their tail also helps steer and stabilize them mid-glide.
- Landing Gracefully: As they approach their landing spot, sugar gliders angle their bodies upward to reduce speed. This helps them reach their target safely, often grabbing onto the bark with their claws and landing precisely on their intended spot.
This gliding ability helps sugar gliders find food, avoid predators, and travel efficiently between trees without descending to the ground, where they’re more vulnerable.
