Identification
Woodchucks (Marmota monax) are
large members of the squirrel family and are
closely related to other species of marmots in
North America. They also are known as ground
hogs and whistle pigs.

Physical Description
Woodchucks usually are grizzled gray-brown
from head to toe. The compact, chunky body is
supported by short strong legs. The forefeet
have long, curved claws that are well adapted
for digging burrows. The tail is short, furred,
and dark brown. As with other rodents,
woodchucks have yellow-white, chisel-like
incisor teeth. The eyes, ears, and nose are
located toward the top of the head, allowing
the animal to remain concealed in its burrow
while checking for danger over the rim of the
burrow opening.
Both sexes are similar in appearance, but males
are slightly larger. Woodchucks weigh 5 to 10
pounds. The total length of the head and body
averages 16 to 20 inches, and the tail is 4 to 7
inches long.
