Caucasian Squirrel

Fascinating facts about the Caucasian Squirrel

• Unlike every other squirrel in Europe, the Caucasian squirrel has ear tufts that grow up to 2 centimetres long — feathery antenna that stick straight up like a lynx's. Scientists still aren't certain what they're for, though some suspect they channel sound waves toward the inner ear, letting these forest dwellers hear predators from further away while their heads are buried in bark.
• This squirrel's range is a geographic puzzle that stumped researchers for decades: populations scattered across the Caucasus Mountains, Turkey, and Iran are separated by hundreds of kilometres with no continuous forest bridge between them. DNA analysis finally revealed they're relics of a once-massive population that shrank during ice ages, now isolated in mountain pockets like islands in a sea of open land.
• Caucasian squirrels cache (bury) nuts with stunning spatial memory — they can relocate hidden seeds from up to 30 metres away months later, using landmarks and an internal map of their territory. In autumn a single squirrel may bury over 5,000 seeds; the ones they forget to dig up often grow into trees, making them accidental foresters that reshape their own habitat.
• Come winter, Caucasian squirrels don't hibernate like ground squirrels do — they stay active all season, relying on their buried seed caches and a winter coat that thickens by 40 per cent. On the coldest days they huddle in dreys (tree nests) made from bark and leaves, sometimes sharing warmth with other squirrels in a survival strategy almost no other tree squirrel in Europe uses.
• In parts of Turkey and the Caucasus, this squirrel is hunted for its tail hairs, which are prized for making traditional artist brushes and fishing lures — a pressure that's erased populations from entire valleys despite its 'Least Concern' conservation label. Local hunting traditions predate modern wildlife management, creating an invisible threat that statistics alone don't capture.

About the Caucasian Squirrel

In the sun-dappled forests of the Caucasus, a diminutive yet dynamic figure darts through the underbrush, its rusty-red fur flaring like a fleeting ember as the Caucasian Squirrel bounds from branch to branch with effortless agility. With a twitch of its bushy tail, it vaults across impossible gaps, its paws barely touching the bark as it weaves a intricate path through the trees, driven by an insatiable hunger for the forest's hidden treasures. As it moves, the squirrel's large, dark eyes shine like polished onyx, drinking in every detail of its surroundings with a fierce and unyielding curiosity.
