Pseudacris crucifer

The spring peeper is a small 2-3cm frog, light brown in colour with a characteristic dark brown cross-shaped blotch extending across the back. Spring peepers are found in temporary woodland pools formed by rain and melting snow in early spring. They are usually encountered in spring as they move to and from woodland breeding ponds. Outside the breeding season they forage in woodlands or amongst shrubs and marshes bordering woodlands.

In March, April and May, large choruses of their "peep... peep... peep..." calls are heard from woodland pools. Males call from grass tussocks, leaves at the edge of a pond, floating twigs, or from low branches overhanging a pond. Males may also call in September or October on rainy nights.
