Overachiever male norhern flying squirrel (Glaucomys sabrinus) moves a pine cone, half his weight, from one cavity cache to another in the middle of the night in winter spruce forest near Seeley Lake in north-central Montana, USA. Several evolutionary innovations in the muscular and neural control of its wing membrane allow for exceptional versatility in flying squirrels gliding and weight lifting abilities.
