Natural Highlights: Calling Chorus Frogs

Even on cold January days, one is likely to hear the calls of male Upland Chorus Frogs (Pseudacris feriarum) in shallow wetland areas, especially when the sun is shining and temperatures reach the 30's and 40's.  The call is unmistakable and has been compared to running a finger along the teeth of a plastic comb. Chorus Frogs are usually found near grassy ditches, flooded fields and temporary wetlands, both in urban areas and out in the country.  The males call to attract females and the frogs breed from January through March or early April.

Upland Chorus frogs are small (3/4 to 1 1/2 inch) brown or grey frogs, with a light line across the upper lip and a dark lateral stripe running through the eye. Markings are highly variable. Generally, there are three longitudinal stripes down the back, but these may be absent or broken.
