The Siberian Flying Squirrel (Pteromys volans) is a nocturnal gliding mammal native to the boreal forests of northern Europe and Asia. With a soft, silvery-gray coat and large, expressive eyes adapted for night vision, it soars between trees using a skin membrane called a patagium that stretches between its limbs. Despite its small size and elusive nature, this squirrel plays an important role in forest ecosystems. A symbol of quiet agility and survival in harsh environments, it’s rarely seen — making any encounter a magical forest moment.
