66 Red Squirrel Facts That Are Sweet As A Nut

Red squirrels are interesting as well as adorable.

The natural world is a fascinating place: as our African Elephant Facts and Mantis Shrimp Facts blogs show, from the biggest to the smallest, there's always something new to discover about the wildlife we share our planet with.

Think of woods in fall and you'll almost certainly imagine a fluffy-tailed squirrel scampering around through the trees stashing nuts to keep it going through the winter ahead. But there's much more to know about these adorable little rodents than just storing food and scrambling up tree trunks.

Red squirrels live all over the world. From the classic English red squirrel that pops up on Christmas cards every winter to Switzerland's black "red" squirrels, the world is full of these fluffy-tailed critters. To keep track of them all, scientists have come up with a system called taxonomy which shows how closely related different animals are. Its system of kingdom, phylum, class, order, family, genus, species shows how different animals relate to each other.

No matter how they're related, we think all those nutty little squirrels are fascinating. We've compiled a list of the most intriguing, unexpected and downright weird facts about the red squirrel population around the world to show everyone they're more than just a fluffy tail.
