Wisconsin Sea Grant Frogs: Field Guide
Call: A series of clucking croaks that resembles
a quacking duck.
Size: 3.5-8.3 cm in length (1.4-3.3 inches)
Grayish brown, tan or bronze, with a dark "mask" extending from
the eye through the shoulder region, and a white line along the upper
lip; possible dark stripes on the hind legs.
Moist wooded habitats throughout the
Great Lakes region.
The Striped Chorus Frog also has a brown mask-like patch on its face,
but is smaller and lacks dorsolateral
Breeding: Late March-April
FACT: In the winter, while many frogs hibernate
in the mud at the bottom of lakes or ponds, the Wood Frog will hibernate
on land beneath loose soil, leaves or decaying logs. They survive freezing
temperatures by producing a natural "antifreeze" in their bodies.

This habit presents a problem if a road is located between these frogs'
forested homes and their breeding ponds.
Each spring, large numbers of adult Wood Frogs can be killed
by automobiles while the frogs are crossing roads to get to and from their
