After a long, cold winter, many of us can’t wait for signs of spring. Whether that be the first glimpse of a robin or flowers starting to bloom, spring brings us all a sense of excitement! However, for those of us in the southern Ontario herpetology community, the first euphoric sign of spring is usually the call of a certain amphibian vocalist.  The western chorus frog (Pseudacris triseriata) is a fingertip-sized treefrog that has a breeding call that resembles the sound of running a finger along the teeth of a comb. Chorus frogs are among the first amphibians to emerge in the spring. They can even be heard calling when there is still snow on the ground – hence their reputation for being the harbingers of spring. Take a listen below to a recording of a group of chorus frogs calling. Have you heard them singing?
