This is, as you can maybe tell from the mown grass it is in, a very small frog. At first I thought it might be a very young Pickerel Frog, but I am thinking it is actually a Spring Peeper. Anyone with more definite knowledge could easily talk me out of the identification. I would even believe a convincing argument that it is a toad.  If I had put a quarter down it would have completely covered the frog, and a nickle would have covered the body. If you are viewing this on a monitor or laptop, the frog in the image is probably 3 to 4 times life size (depending on your viewing screen). It was making hard work of moving through the grass. It basically had to climb over the stalks.
