How It Works

When it’s frosty outside, why don’t wild animals die?

Wildlife in the UK is well prepared for wintery conditions and have adapted in a variety of ingenious ways to cope with the cold. Some, such as the hedgehog and dormouse, have opted to skip winter altogether by hibernating. Others, such as squirrels and jays, anticipate the short supplies of food by caching stores to see them through. Thick fur coats, layers of fat and insulating feathers help shield stoats, seals and swans from the biting cold much more efficiently than clothing ever could, and birds such as thrushes switch their diet to berries high in sugar to generate essential warmth.
