Iowa’s native base-jumper, the southern flying squirrel (Glaucomys volans), is easily identifiable because of the wing-like membrane (patagium) that stretches between the wrists of the front legs to the ankles of the back legs.  This membrane looks like the wingsuit base-jumpers use when gliding through the air. The southern flying squirrel doesn't actually fly.  However, it can glide over 250 feet in one leap!
