Boreal Chorus Frog (Western Chorus Frog)
This small frog—formerly called the western chorus frog in our state—may be gray or tan; has three wide, dark stripes or a series of spots down the back; and a wide, dark stripe passing through the eyes and extending along the sides. There is usually a dark marking on the head between the eyes, and the upper lip is white. The belly is white, sometimes with a few gray spots on the throat and chest. Breeding males have dark throats. The call is a rasping, vibrating “prrreeep” that sounds similar to running a fingernail over the teeth of a pocket comb.
