| Chicks are ringed and wing-tagged before fledging with flexible wing-marks fixed on patagium by aluminium staples on the top of each wing. |
|
| They glide, by taking off from a high perch, spreading a special membrane called a patagium, which resembles a bat wing, and soaring up to 150 feet to another tree. |
|
| The best preserved impressions of patagium in Pterodactylus show the membrane connected to the thigh about two-thirds of the distance along the femur. |
|
| The patagium extends all the way around to the bat's hind legs and tail, where it forms a flap called the uropatagium, supported by specialized foot bones called calcars. |
|
| The patagium is stretched between the arm and hand bones, down the lateral side of the body and down to the hind limbs. |
|
| The squirrel can change direction by leaning to one side or the other, and by raising or lowering its wrist bone to adjust the tightness of the patagium. |
|
| Similar to the flying squirrel's patagium, the wingsuit turns the human body into an airfoil, providing a reactive force or lift, when in motion relative to the surrounding air. |
|
| Because of the high energy demand of flight, the bat's body meets those demands by exchanging gas through the patagium of the wing. |
