Northern Flying Squirrel Distribution, Habitat, and Ecology

The fantastic Northern Flying Squirrel evolved as indigenous to a part of the globe already well known for its abundance of wildlife. That’s due to the fact that the amazing rodent lives on the continent of North America. There, though, its population remains somewhat disjointed in nature.

As its name implies, the great majority of its numbers appear in the northern part of the continent. More specifically, most of its population lives in the nation of Canada. It also appears as far north as the state of Alaska, though. The small wonder of Nature also appears in the United States.

In that country, it’s population’s scattered, though. To the west, it’s seen in California and Colorado. From there, it’s also observed to the northeast in Ohio, Wisconsin, and Michigan. In the east, the animal also lives in regions of Tennessee and North Carolina, in the Appalachian Mountains.

In each of these entirely separate regions, however, it displays identical habitat preferences. Populations most often appear in areas dominated by conifers. Some do, though, make their homes in regions of deciduous or mixed forests. It also prefers dense concentrations of trees, as well.

The wondrous Northern Flying Squirrel evolved as a mainly nocturnal animal. It’s also primarily arboreal in nature. On the ground, it’s relatively clumsy. Among the trees, though, it glides from limb to limb gracefully. Its main predators include hawks, owls, martens, and coyotes, among others.

Its diet remains typical of its kind. As a herbivore, it consumes a wide variety of locally available food. This fare typically includes such staples as various nuts, fungi, acorns, lichens, fruits, buds, and even tree sap. It does, however, occasionally supplement this with insects and even bird eggs.
