Bronze Frog
Rana (Lithobates) clamitans

Size:  6 - 8 inches
Eastern 1/3 of the state.  The bronze frog, and the closely related green frog, look very similar to bullfrogs in that they are usually rather uniform green in coloration, but differ in that they have nearly complete dorso-lateral folds running down each side to the hind legs. They also have a more pointed snout, somewhat like a leopard frog. The male bronze frogs have a very distinct banjo-like "gunk-gunk" call and can usually be heard calling near a permanent water source. Like most ranid frogs, the males can be easily distinguished from the females by the size of the tympanum, the large round eardrum located behind each eye. The frog pictured above is clearly a male.
