What Exactly Are Flying Squirrels?

Another misunderstood animal, the flying squirrel. One of the coolest looking animals, so let’s see why they are misunderstood.

Rocky, The Flying Squirrel

Never thinking much about flying squirrels, we were thrilled to learn they live all around us in North Carolina. Our first exposure to flying squirrels? Watching Rocky & Bulwinkle as kids a million years ago. If you are too young to remember, it is a great cartoon about Rocky, a flying squirrel & his pal, Bulwinkle, the moose. You can still see some of the old shows on YouTube.

So back to real flying squirrels. If you see something swooping overhead at night, it might not be a bat, but a flying squirrel. But are they actually flying? Nope, they are gliding from tree to tree,  using a patagium. Hmm, that is a new word for us.

What Is A Patagium?

It is a membrane made of fur that stretches from the wrist to the ankle and acts like a parachute when the flying squirrel leaps from a tree. Using the patagium and their tail, the flying squirrel is able to steer while gliding with flights recorded up to 300 feet. Wow, that is a long way! They can also turn 180 degrees.

Watch flying squirrels fly (ok, glide) in this amazing video narrated by David Attenborough. Just amazing.

And come to find out, flying squirrels have been around for 18-20 million years. But we rarely see them since they are nocturnal, which is one reason their eyes are so big. They need to be able to see in the dark while gliding and foraging.

So what do these guys eat? Well, they love truffles and other fungi. They also eat mushrooms, bird eggs, insects and flowers, making them omnivorous (meaning they eat plants & animals).

Plus lots of nuts especially during breeding season when the mothers need additional nutrition. And flying squirrels have been known to store up to 15,000 nuts. Wow, how do they remember where they all are located?

Endangered  Carolina Northern Flying Squirrel

Out of 45 species of flying squirrel around the world, we have 3 in North America. The northern, the southern & the Humboldt’s flying squirrel (located in the Northwest US). Here in North Carolina, we have the southern flying squirrel except…

High in the mountains of Western North Carolina, you will find the  Carolina northern flying squirrel, a subspecies of the northern flying squirrel. With only 9 known populations in existence, all above an elevation of 4,500 feet, not only is it endangered but very elusive.

So we were incredibly lucky to actually see a Carolina northern flying squirrel on a weekend trip to Western North Carolina. A once in a lifetime event.

And just how did our amazing discovery of this incredibly secretive animal come about? A couple of mysterious tall poles on either side of a road called The Cherohala Skyway high up in the mountains led to our encounter.

The Mysterious Poles!

What in the world is the purpose of these poles we wondered? There were 3 sets of 2 each spaced along the highway. Something having to do with snow? But what were the round, PVC tubes attached at intervals going up the poles? Quite the mystery.

So we asked our innkeeper, Robert Rankin, at the Snowbird Mountain Lodge about the poles. He told us the story of the Cherohala Highway being built, a $100 million dollar project. Unfortunately, the road was so wide, the Carolina northern flying squirrels could not glide across it.

Something had to be done! The North Carolina Wildlife Resources Commission with the aid of North Carolina Department of Transportation, Duke Energy, U.S. Fish and Wildlife Service and the U.S. Forest Service got together to come up with a solution. They constructed poles to act as landing and launching spots for the squirrels to use in crossing the highway. And they seem to be working!

The PVC tubes are for hiding from predators while the flying squirrels are up on the poles. How cool is that! 

Other Cool Facts

Flying squirrels have many predators including owls, raccoons, and snakes. They nest high in trees and their young are born without any fur. The babies stay with their mom for a couple of months nursing & then leave to live on their own after about four months.

it is not unusual to have a number of flying squirrels all pile into one nest, especially in the colder months. Now that would be a sight.

But the coolest fact? They glow in the dark. All North American flying squirrels have a pink glow at night. So if you see a pink light go gliding by you in the middle of the night, it just might be a flying squirrel.

How can you help these cute squirrels, especially the endangered Carolina northern flying squirrel?

Learn more about them and spread the word on social media.

Support an initiative by the Southern Highlands Reserve.  The  Carolina northern flying squirrel feeds on fungus living at the base of conifers at high elevations. Unfortunately, many of the trees (hemlocks, Fraser firs & red spruce trees) have been decimated from non-native pests and climate change.

Several groups have partnered to plant new spruce trees in the squirrel’s habitat with over 4,000 planted to date. And Southern Highlands Reserve is the only plant nursery growing the seedlings needed.
