Identification

The Spring Peeper is one of Vermont’s smallest frogs. Adults are generally 1-1½ inches long. The Spring Peeper has no dorsolateral ridges. It has dark markings on its back that usually form an “X”, and small adhesive discs on its toes. Spring Peepers vary in color from light to dark brown. Adult males are generally smaller than the adult females, and breeding males have black throats and swollen thumbs.

Its call can either be a short ascending whistle or it may be broken into a series of ascending peeps. It begins calling as early as March, and can be heard through July. The peak calling time is around the beginning of May.

After mating, Spring Peepers lay hundreds of eggs singly or in packages of 2-3 eggs attached to vegetation. Tadpoles metamorphose within 2-3 months.

Range/Habitat

Adults can be found in herbaceous vegetation or woods next to heavily vegetated swamps and marshes of all sizes.
