The hyla, or little piping frog, passes the winter in the ground like the wood frog.
A friend of mine, one mild day late in December, found a wood frog sitting upon the snow in the woods.
wood frog (R. sylvatica), pale reddish brown; a black band across the pointed face.
Among the sylvan denizens that next came upon the stage were a hummingbird, a little red newt, and a wood frog.
In two instances I have found the wood frog in December with a covering of less than two inches of leaves and moss.
