Spring Peepers Peeping

The peeps of male Spring Peepers can be heard fairly consistently this time of year. Unlike in the spring, these calls are coming not from bodies of water, but from the woods nearby. And they are single peeps coming from individual peepers, not the chorus of “sleigh bells” one hears in the spring. This phenomenon occurs so regularly in the fall that herpetologists have given it a name – “fall echo.” They speculate that the calling of peepers is spurred by light and temperature conditions that mimic those that occur in the spring, during Spring Peeper mating season.

    When I first started birding these single peepers had me wondering what bird was calling!

    Coincidentally, I was sitting on the steps, yesterday & saw a wee Peeper sitting on a basil leaf!
