This week on Discover Nature take a walk outside, and you may hear one of the first serenades of spring on the horizon.
Spring peepers have spent the winter burrowed under soil – a natural antifreeze in their blood keeping them thawed.
One of the first species to begin calling in the spring, this small, slender frog can appear pink, gray, tan, or brown, with a dark ‘X’ on its back.
Roughly one-inch in length, they breed in fishless ponds, streams and swamps with thick undergrowth.
