East Tennessee Frog Calls
This page presents audio recordings of frog calls commonly heard in eastern Tennessee. Listening to the recordings will allow you to identify frogs and toads by their vocalizations. The time of year when frogs and toads call depend on when each frog or toad species breeds. In East Tennessee, some species can be heard calling from December through late winter, while others can be heard in late spring and early summer. For additional information about frogs and toads in Tennessee, see the Tennessee Wildlife Resources Agency "Frogs and Toads of Tennessee" Web site.
