Spring Peepers

At night, the strident call of Spring Peepers (Pseudacris crucifer), the ducklike clacking of Wood Frogs (Rana sylvatica), and the short trill of Grey Tree Frogs (Hyla versicolor), fill the air around every bog and wet place. Later in the summer, these tiny amphibians are sometimes found while walking in the woods and fields, mistakenly called baby frogs by the young children who can’t resist picking them up to show to their parents. At maturity, the tiny, brown Spring Peeper is just 3/4 - 1 1/4 inches in size. The nocturnal Spring Peeper is found in wooded areas in or near permanent or temporarily flooded ponds and swamps and hibernates under logs and loose bark. The Grey Tree Frog is 1 1/4 - 2 inches. The nocturnal Grey Tree Frog lives high in trees and descend only at night, usually just to chorus and to breed. The Wood Frog, brown with a bandit's mask of black behind its eyes, is only slightly larger at 1 3/8 - 2 3/4 inches. In the colder parts of its range, the Wood Frog is an explosive breeder. Swarms of pairs lay fertilized eggs within 1 or 2 days, then disappear into the surrounding country. It may venture far from water during summer, and hibernates in forest debris during winter. The Spring Peeper, a Chorus Frog, and the Grey Tree Frogs are members of the Tree Frog Family (Hylidae), while the Wood Frog is a member of the True Frog Family (Ranidae) and closely related to the familiar Leopard Frog.
