Hyla crucifer, if I remember correctly from the old book of eastern reptiles and amphibians I used to own. I can still see the little X on its back that distinguishes the spring peeper, hence the crucifer meaning cross in its scientific name. It was a right of spring for me to trudge out into the woods on early spring nights that were cool enough to turn my breath into mist. I was always amazed at how cold the water still was, yet these miniscule frogs still called to their mates from those same waters. Just the other night in the small marsh in my York, PA area neighborhood I too heard the familiar call of spring from these frogs. Having lived in a arid western state for the last 7 years the sound was welcomed and soothing to my ears and memory. Spring is officially here for me as the peepers are peeping and I look forward to sharing this spectacle of sound with my son on some crisp evening in the coming weeks.

I once heard spring peepers at a pond in Virginia, but don't remember where it was. I now live in Bethesda and would love to take my kids to hear some peepers. Where, near Bethesda, would I be likely to hear them? And are they still singing this late in April? Thanks!
