High-pitched whistles and short trills ring out from wetlands, too.
Spring peepers are beckoning mates, weeks before their namesake season arrives.
Up North, the little frogs emerge in the mild spring rains that melt snow. In South Carolina, it takes chilly winter rains to put the amphibians in the mood. Males may tune up in late fall and continue into next month, but recent drizzly and rainy nights have spurred them to full voice. Each frog whistles a rising, bird-like peep about once a second, but as a chorus the peepers sound more like jingling bells. Living under fallen forest leaves or in brushy undergrowth, peepers use suction pads on their feet to climb trees and shrubs standing in or hanging over water, quiet water where females will want to lay their eggs.
