Flying squirrels have two flaps of skin connecting their forearms to their body, which allows them to "fly" from tree to tree.
Combat
Flying squirrels avoid combat, using their gliding ability to quickly escape enemies.
Glide (Ex): A flying squirrel can glide from any height at a speed of 20 feet per round in moderate or lower winds, descending at a rate of 10 feet per round.
Skills: Flying squirrels have a +8 racial bonus on Balance, Climb, and Jump checks. A flying squirrel can always choose to take 10 on a Climb check, even if rushed or threatened. A flying squirrel uses its Dexterity modifier for Climb and Jump checks.
