Virginia Northern Flying Squirrel (Glaucomys sabrinus fuscus)

Who isn’t interested in a flying squirrel? You are because you’re here!

The Virginia Northern flying squirrel (Glaucomys sabrinus fuscus) is actually considered rodents and tends to be gray or brown in hue with silvery fur on their underbellies. Also, the squirrels don’t actually fly; they have a membrane between their wrists and ankles, called a patagium, which they use to glide from tree to tree. The squirrel is nocturnal, so they share the features of other nocturnal animals, such as large eyes and long whiskers.

The squirrel makes in the holes of trees, either natural or those made by woodpeckers. They may also create nests out of twigs, bark, and other items to soften it. They make their nests anywhere from 1 to 18 meters off of the ground, and the forests they tend it inhabit tend to be diverse mix of trees with abundant growth. They also like to nest in trees with denser canopies to protect them from predators and extreme temperatures. The squirrels live in small communities, generally staying in clusters of 2-5, but have been seen with up to 50 living together. The squirrels don’t hibernate during the winter, so to stay warm they must huddle together when they sleep.

The squirrel makes meals out of nuts, insects, lichens, the same as other squirrels, but also can make a diet of lichen an interesting fact is that they can find truffles like pigs. However, unlike pigs, they can use visual clues and remember where truffles were found last, as well as searching for them by smell.

The Virginia Northern flying squirrel is on the brink of extirpation because the industries are cutting down forests, logging, climate, mining, drilling, and road building. These things are destroying the older trees and fallen growth, which sustain the squirrel’s life. Also, when these trees are cut down it opens up the canopies, which expose the squirrel to harsher climates than they are used to, and predators. It also closes off routes, which isolates squirrels from others of their kind. I don’t believe that Global Warming would have any effect on this species, whatsoever.

The way that we can protect the squirrel is obvious; we have to stop destroying their habitat, plain and simple. It’s hard to relocate them to another protected area because they need an older habitat that is densely forested with fallen trees where lichen and fungus are prominent.
