Sounds of Spring - Spring Peepers

We spent the past week in the Traverse City area.  When we pulled up to our hotel on Friday night we immediately noticed a familiar sound.  The area behind the hotel is basically a shrub swamp and this weekend that swamp was hosting dozens of male Spring Peepers (Pseudacris crucifer) each hoping to attract a mate with his peep peep peep calls.  The louder and more frequently a frog call, the better his chances of attracting a mate.  There was also at least one Western Chorus Frog (Pseudacris triseriata) that periodically adds his voice.

It didn't happen while I was recording, but at one point a storm passed through with a loud crack of thunder.  Every single frog, which to that point had been vociferously calling, immediately went silent.  The effect was enough to make me chuckle.
