Length 3/4 - 1 1/2 in. (2-4 cm). The Western Chorus Frog is often confused with the Spring Peeper since they’re similar in size and live in similar habitats. Like the Peeper, the Chorus Frog emerges from hibernation with the thawing of the ice and congregates by the hundreds in small ponds. The Chorus Frog’s call resembles the sound made by rubbing one’s finger over the teeth of a hard plastic comb instead of the birdlike whistle of the Peeper. There are usually three distinctive dark stripes on the back extending from the nose across the eyes and on along the length of the body. In some populations the three stripes are broken into three rows of spots. After the breeding season, Chorus Frogs are seldom seen. They probably retreat deep into mud to escape the heat of summer. Originally, this was chiefly a frog of the prairies, but it was able to extend its range as the eastern woodlands were cleared for agriculture.
