The bronze frog is Rana clamitans clamitans and is found in the SE US. The green frog found more throughout the E US is Rana clamitans melanota and my guess is that's what this guy is. Usually they have a green face, but they can also have a bronze/brown face. Unfortunately we don't have them here so I haven't had any "face to face" time to be 100% confident in that ID.
