The Spring Peeper is a small 2-3cm frog, tan to brown to gray, with characteristic dark X marking on its back.

A high-pitched ascending whistle, "peep... peep... peep”. Chorus sounds like the jingle of bells. Males call from shrubs and trees standing in or overhanging water. Breeding season is March to June, with the start of warm rains.

Spring Peepers are found in wooded areas in or near permanent or temporarily flooded ponds and swamps. These nocturnal frogs are one of the most familiar frogs in the Algonquin Highlands. Peepers hibernate under logs and loose bark.

Where urbanization is occurring, the Chorus Frog seems to be displacing the Spring Peeper. Chorus Frogs thrive in more exposed sites than do Spring Peepers; perhaps the loss of woodlots and lowering of water tables in urban areas have created conditions that favour the chorus frog.
