Caucasian Squirrel (Sciurus anomalus) lives in temperate forests across Southeastern Europe and Asia. It feeds on nuts and seeds. Its conservation status is Least Concern.
Fascinating facts about the Caucasian Squirrel
- The Caucasian squirrel was first formally described by Johann Anton Güldenstädt in 1785, not by Gmelin as often claimed. Although the species is traditionally said to have been described in 1778 by Gmelin, that work was actually published in 1788, so the earlier description stands. Gmelin later cited Güldenstädt as the author in his 1788 publication, confirming the correct attribution.
- Caucasian squirrels can amass food stores far exceeding their own mass, with individual caches holding up to 6 kg of seeds while the animals themselves weigh only 250 to 410 g. They hide these larders in tree cavities or loose soil, allowing them to survive periods when fresh food is scarce. Such large reserves are especially valuable during winter months when preferred oak and pine seeds are less available.
- Only two members of the genus Sciurus naturally inhabit Mediterranean islands, and the Caucasian squirrel is the sole native Sciurus across the broader region. While Eurasian red squirrels have been introduced to some locales, they are not indigenous. This unique distribution makes the species a key representative of native Sciurus fauna on both islands and mainland habitats.
- After retreating northward in the Late Pleistocene, the Caucasian squirrel left behind relic populations in Israel that persist to the present. Earlier, it had spread southward into the Levant during the Last Interglacial, expanding its range before the retreat. These Israeli groups are therefore living remnants of an ancient distribution that once covered much of the region. Today the species still occurs in Israel as part of its broader south-western Asian range.
- When alarmed, the Caucasian squirrel emits a high-pitched call that resembles the cry of the European green woodpecker, a sound it uses to warn conspecifics of danger. The species is diurnal and generally solitary, but individuals will still broadcast this alarm while foraging alone on the ground or in trees. In addition to vocal warnings, it marks its territory with urine and dung, leaving scent cues that help define its home range.

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.
