Carolina Northern Flying Squirrel
(Glaucomys sabrinus coloratus)
The Carolina northern flying squirrel is one of two species of flying squirrel in
North Carolina (the other is the southern flying squirrel). Contrary to their name,
flying squirrels do not truly fly. Rather, they leap from trees using their powerful
hindquarters, stretch out their limbs, and glide to the ground or nearby trees. A
cape of skin that stretches from their wrists to their ankles, called a patagium, acts
as a wing-like surface as they glide downwards. Flying squirrels drop about a foot
for every three feet of forward glide.
Description
The flying squirrel’s most distinctive feature is its patagium. Carolina northern
flying squirrels have bright cinnamon- brown fur dorsally, gray fur around the face
and the end of the tail, and bicolored fur on the belly (gray at the base and creamy
white at the tip of each hair). The squirrel has a long, flat, furred tail.
The Carolina northern flying squirrel resembles the smaller, more common
southern flying squirrel (Glaucomys volans) but is nearly twice as large. While there
is some elevational overlap in their range between 4,000 to 5,000 feet, Carolina
northern flying squirrels are restricted to the highest elevations while southern
flying squirrels are found most commonly at lower elevations.
History and Status
Biologists first discovered the Carolina northern flying squirrel in North Car-
olina in the early 1950s. When the federal government listed it as Endangered
in 1985, funds became available to study its distribution. This species inhabits
eight mountain ranges in North Carolina: Long Elope, Roan, Grandfather, and
the Black- Craggy Mountains north and east of the French Broad River Basin, and
Great Balsam, Plott Balsam, Smoky, and Unicoi Mountains south and west of the
French Broad River Basin. Recently, it has been documented in a ninth mountain
range, Unaka Mountain.

Habitats & Habits
The Carolina northern flying squirrel inhabits the boreal and deciduous forests of
North Carolina’s highest mountains. It prefers a mix of conifers (red spruce, Fraser fir,
Eastern hemlock) and northern hardwood trees (yellow birch, buckeye, sugar maple).
It forages in the conifers and dens in hardwood trees. Dens are found in live and dead

Range and Distribution
The northern flying squirrel is found across
Canada and the northern United States, its
range extending southward in the mountain
chains of North America. North Carolina is
the southern extent of this species in east¬
ern North America, with the Carolina sub¬
species distributed in the highest mountains
of western North Carolina, east Tennessee,
and southwest Virginia. It had a wider range
during glacial times, when boreal forest was
much more extensive.
