15 Weird Squirrel Facts That Explain Why They're Always Up to Something

They're not just stealing birdseed. They're running a whole operation.

Fall is peak squirrel season, when your backyard turns into a frantic nut-burying factory. These little acrobats are way smarter (and sneakier) than they look. Here are 15 real squirrel facts that might change how you see the furry guy staring at you from the fence.

1.They accidentally plant trees

Squirrels bury so many nuts that a few always get left behind. Those forgotten ones can sprout, which means squirrels help spread oak trees and other nut trees. Accidental gardeners, every single one.

2.They hide nuts in thousands of spots

Gray squirrels are "scatter hoarders," meaning they don't keep one big pantry. They bury their food one nut at a time in spots all over the place, and a single squirrel can stash thousands of nuts in a season.

3.They fake-bury nuts to fool thieves

Researchers have seen gray squirrels pretend to bury a nut when they think someone is watching, then sneak off with it. They dig a hole, cover it up and walk away with the snack still in their mouth. Diabolical.

4.Some sort their stash by type

A study of fox squirrels found they tended to bury nuts in groups by type, like almonds in one area and hazelnuts in another. Scientists think it may help them remember where everything is. They're more organized than most junk drawers.

5.They weigh nuts with a head flick

Ever see a squirrel flick a nut around in its mouth before deciding what to do? Researchers think those quick head flicks help it judge how heavy (and how good) a nut is before it decides to eat it or save it.

6.Their front teeth never stop growing

Like other rodents, squirrels have front teeth that keep growing their whole lives. All that gnawing on nuts, bark and the occasional patio furniture keeps them from getting too long.

7.They can turn their back feet around

Squirrels can rotate their back ankles so their feet point backward. That lets them dig their claws into the bark and run down a tree headfirst without tumbling off.

8.Their name means "shadow tail"

The word "squirrel" traces back to a Greek word that roughly means "shadow tail." Fitting, since they sometimes hold that big fluffy tail over themselves like a built-in umbrella.

9.Their tail is a whole toolkit

That tail helps them balance on skinny branches, keeps them warm when they curl up and helps shade them from the sun. It's a blanket, an umbrella and a balance pole in one.

10.They talk with their tails

When a squirrel spots danger, it often flicks or waves its tail, sometimes while chattering loudly. It's a warning to the neighborhood and a message to the predator: "I see you."

11.Flying squirrels don't actually fly

Flying squirrels glide. They stretch out a furry flap of skin between their front and back legs and sail from tree to tree, steering with their tails. Still extremely cool. Just not technically flying.

12.Some flying squirrels glow pink

In 2019, scientists reported that North American flying squirrels glow pink under ultraviolet light. Nobody is totally sure why. They've basically been secretly running a nighttime rave this whole time.

13.A groundhog is a squirrel

Groundhogs, chipmunks, prairie dogs and marmots all belong to the squirrel family. So yes, the famous weather-forecasting groundhog is technically just a very large, very serious squirrel.

14.Some red squirrels make maple snacks

American red squirrels have been seen biting into sugar maple bark, letting the sap drip, then coming back later to lick up the sweet, dried-out syrup. Squirrels figured out maple treats long before pancakes did.

15.Some towns are famous for white squirrels

A few U.S. towns, including Olney, Illinois, and Brevard, North Carolina, are known for their populations of white squirrels. Locals are very proud of them, and honestly, fair.
