Spring Peepers and two other frog species calling in early spring

I grew up in a swampy rural area where Spring Peeper frog calls were a prominent and peaceful sound of early spring. Their peeping starts at just about my childhood bedtime. For a blissful few weeks in March or April I'd fall asleep to their persistent drone. This delicate whistle-like call is one of my favorite sounds on earth.
