I guess the mild temperatures have thawed the frogs and fired their libidos. Wood frogs are remarkable creatures. They are the most widely distributed amphibian in North America and the only North American frog found north of the Arctic Circle. They have two prominent dorsolateral ridges along their back. A dark, mask-like stripe extends from the snout, around the eye and ends behind the tympanum, or eardrum.
Frogs are among the oldest creatures on the planet.
They are believed to have evolved from the Ichthyostega, the earliest known amphibian, during the Devonian Period, more than 300 million years ago. Fossil records of frogs as we know them today extend back 190 million years. Perhaps one reason for their longevity as a species is their adaptability. They are found on all continents except Antarctica. While most people associate frogs with moist temperate climates, they are also found in deserts and on mountains at elevations of 15,000 feet.
