The wood frog, Rana sylvatica is found from northern Georgia and in isloated colonies in the central highlands in the eastern to central parts of Alabama, up through the northeastern United States, and all the way across Canada into Alaska. It is found farther north than any other North American reptile or amphibian. This species exhibits a number of color morphs, usually browns, tans and rust, but can also be found in shades of green and gray. In all cases however, they can be distinguished by a black patch that extends over the tympanum to the base of the front limb. They are also known to have a white spot on the upper lip.
Most specimens also have a light yellowish brown middorsal lateral fold.
The underparts of the frogs are yellowish and sometimes greenish-white, with male frogs having more brilliant colors on the ventral aspect of the legs. Food Habits Wood frogs eat a variety of insects and other small invertebrates, especially spiders, beetles, bugs, moth larvae, slugs and snails. They are the first frogs to begin calling, often before the ice is completely off the breeding ponds. These frogs mate as early as March and the breeding season will last until the beginning of May at the very latest. While the calls of these male frogs are very abundant in season, it is believed that once the breeding season is over you will no longer hear their calls.
