cause it couldn't offset tooth growth.
Gnawing on nuts, seeds and wood
keeps their teeth sharp and short.
What gets most of our more common squirrels in trouble is their habit
of gnawing on "people" property.
The elusive squirrels that are
rarely seen and call Pennsylvania home are two species of flying
squirrels, the southern flying squirrel (Glaucomys volans) and the
northern flying squirrel (Glaucomys
sabrinus). Both species are small, up to
11 inches from the tip of the nose to
the tip of the tail
and look very similar to one another,
except for coloration. The northern flying squirrel
has soft gray or
cinnamon brown
fur on its back
with creamy white
fur on its belly,
while the southern flying squirrel
ranges from tan
to reddish-brown.
The southern flying squirrel is a little
smaller than its northern cousin
and is significantly more common.
They both have large eyes so they
can better see during their nighttime acrobatic forays that begin
about an hour after sunset. You would
think that northerns and southerns
would be happy to live together and
sometimes they can be found in the
same nest boxes. However, each
has its own list of special needs and
housing is just one of them that
is nearly the same. As is often the
case with mammals, one species
outcompetes the other, and in this
FEBRUARY 2014

case it's the more aggressive and
numerous southern flying squirrel
that pushes G. sabrinus out. Even
though crossbreeding has been
discovered, it's not common.
H i s t o r i c a l l y, n o r t h e r n f l y ing squirrels appeared across the
northern tier of the state and south
through the Laurel Highlands, where
their preferred mature red spruce,
balsam fir and eastern hemlock
trees thrived in uninterrupted forests.
Times have changed. Game Commisison biologist Greg Turner assisted with
an extensive study
on northern flying squirrels from
2001 to 2007. The
study was conducted in Pennsylvania in cooperation with Wilkes
University and
the Pennsylvania
State University,
Altoona Campus.
Only 33 northern
flying squirrels
were found.
The study led to the designation of
the northern flying squirrel as a state
endangered species.
Most known locations where northern flying squirrels live are in the Pocono
region, with the exception of one in
Warren County and one in Potter County. So when I was collecting information for a story about
northern flying squirrels, Greg invited me to join him in the
field for nest-box inspections
while working on his research. I
was lucky enough to be there when
he found three northern flying
squirrels cuddled into a corner of
