A spring peepers' chorus in Michigan

Saw this little guy in my backyard. He was sitting in a patch of Cerastium, a.k.a. Snow in Summer. The peepers are singing loudly in the wet spots out in the fields, the prettiest voice of all the amphibians. It's funny, all these years Herb thought I was talking about birds when I said 'spring peepers'.
