Squirrels are mammals in the family Rodentia (rodents) and are
commonly separated into two main types: tree squirrels and
ground squirrels. This fact sheet contains information on
tree squirrels native to Georgia. It would be hard to find
anyone in Georgia who is not at least somewhat familiar with
squirrels. Indeed squirrels are one of the most common and
recognizable kinds of wildlife found in Georgia.
Description and Distribution
The
gray squirrel (Sciurus carolinensis) is the most common
species in Georgia. It is found statewide in both rural and
urban areas. Gray squirrel adult weights range from 12 ounces
to one and a half pounds. Though there is some color variation
among gray squirrels, most are very similar in appearance. The
slightly larger and more variably colored fox squirrel (S.
niger) is also found statewide, but is less common, more
habitat specific, and has more of a sporadic, patchy
distribution. Adult fox squirrels range in weight from one
pound to nearly three pounds. Their pelage (hair) is
extremely variable, ranging from pure black to pure blond with all
sorts of intermediate color schemes. Red squirrels
(Tamiasciurus hudsonicus) are only found in the higher
elevations of northeast Georgias Blue Ridge Mountain
province. They are smaller than both fox and gray squirrels.
This fact sheet focuses on gray and fox squirrels.
Habitat Requirements & Feeding Habits
Both gray
and fox squirrels are associated with wooded habitats. Although
they are often found together in the same area (sympatric), there
are some differences in their preferred
habitats.
In rural
Georgia, gray squirrels are most numerous in mature upland and
bottomland hardwood forests. These forested areas usually
contain a diversity of oaks and hickories (hardwoods). Though
mostly associated with hardwood forests, gray squirrels can also be
found in mixed pine/hardwood forests, especially where availability
of pure hardwoods stands is lacking. In developed areas gray
squirrels can be found in parks and neighborhoods. Gray
squirrel densities can be quite high in urban and suburban
areas.
Fox
squirrels in Georgia tend to be most closely associated with mature
pine and mixed pine/hardwood habitats. Extensive mature
Piedmont and Coastal Plain pine stands with open understories and
herbaceous ground cover seem to be especially dominated by fox
squirrels with little or no occurrence of gray
squirrels.
Oak acorns
and hickory nuts provide the most nutritious food for gray
squirrels, and they will also eat the flowers of these trees in the
spring. Gray squirrels eat a variety of other foods including
buds and flowers of other trees, dogwood fruit, mulberries,
blackgum fruit, grasses and various forbs.
Fox
squirrels will eat many of the same foods as gray squirrels,
including acorns and nuts of those oaks and hickories often found
scattered in upland pine habitats. Pine seeds are a major fox
squirrel food item and they will consume various other foods such
as buds and fruits of other trees and fungi. A small portion
of both gray and fox squirrel diets is comprised of animal matter
such as insects and other arthropods and small
vertebrates.
Reproduction & Mortality
Both gray and fox squirrels will use leaf nests and cavity
nests. The use of cavity nests is probably dependent upon
availability. Many mature oaks have cavities in the bole or limbs
of the tree that provide protective cover for nesting. Fox
squirrels tend to use more leaf nests than gray squirrels.
There are
two separate peaks of breeding activities in both gray and fox
squirrels in Georgia. The first breeding time is in late
winter and the second occurs in late summer. Not all females
will raise two broods a year, however. The ability to
conceive and raise two broods appears highly dependent on adequate
food resources.
About two or three young are born in each litter. The female
rears the young squirrels. They are born blind and
helpless. They develop rapidly, however, and are weaned
around 8-10 weeks of age for gray squirrels and 8-12 weeks for fox
squirrels.
Both gray
and fox squirrels have been known to reach ten years of age in the
wild, but the vast majority of them probably only live a couple of
years. Though not thought a major mortality factor, predation
by snakes, raptors and mammals such as foxes and bobcats causes
some mortality. Many different parasites and diseases also
can lower squirrel survival.
Management and Nuisance Control
Squirrels
are game animals with a defined hunting season and daily bag
limit. In terms of number of hunters and harvest, squirrels
are the number two small game species in Georgia behind
doves. During the 2002-2003 hunting season, 65,000 hunters
harvested 803,000 squirrels. Squirrel hunting, especially
with squirrel dogs such as feists and curs, is a great way to
introduce a youngster to the sport of hunting.
In some
situations squirrels can become a nuisance. They are
notorious for robbing bird feeders. They also get into
houses, especially attics. Trapping or shooting squirrels are
effective nuisance management strategies. Contact a Wildlife
Resources Division Game Management office to see if a permit is
required. Many times habitat modification such as
trimming tree limbs away from houses and squirrel proofing bird
feeders is all that is needed to prevent nuisance
situations.
