I almost missed seeing this well-camouflaged fellow yesterday in a nearby pond. (Sex assumed.) He was only about two inches long. I think that he’s a northern green frog (Lithobates clamitans melanota), although he’s perhaps the most speckled green frog I’ve ever seen.
Those speckles make him seem, to my old eyes, bewilderingly similar to the mink frogs (Lithobates septentrionalis) that I’ve seen only in photographs, and am told never appear this far south in Maine.
Unfortunately, he didn’t utter a call, so I didn’t hear the green frog’s distinctive banjo-like “plunk.” Nor did I get anywhere near close enough to cause or smell any defensive foul odor that he might emit, a reported characteristic of mink frogs, especially if handled.
