Baby squirrels are called kittens, and they enter the world blind, hairless and completely dependent on their mother for warmth and care.

Today's image shows a Eurasian red squirrel perched in the snow, highlighting the thick winter coat and distinctive ear tufts that set this species apart. Native to forests across Europe and parts of Asia, red squirrels depend on a varied diet of seeds, nuts, buds and fungi. To prepare for colder months, they scatter food stores across their territory and construct well-insulated nests—called dreys—inside tree hollows or high among branches.

Despite their reputation as garden raiders or urban 'nuisances,' squirrels play essential roles in local ecosystems. By burying seeds and failing to recover every cache, they unintentionally aid tree growth, particularly among conifers, which rely on ground dispersal. Unlike animals that hibernate, red squirrels stay active throughout winter, timing their foraging trips between snowfalls and relying on memory and scent to locate hidden supplies. Their fur not only provides warmth but also improves camouflage against snowy backdrops.

Small, alert and endlessly busy, they're a reminder that even the smallest creatures have big strategies—and plenty of attitude—to match the cold.
