TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of February 19, 2018.
SOUND - ~5 sec – rainfall in Blacksburg, Va., April 21, 2015
This week, that sound of a Virginia spring rain opens an episode on creatures who show up, sound off, and pair up every year, especially in spring, in temporary ponds and other water bodies. Have a listen for about 40 seconds to a series of mystery sounds, and see if you can guess what animals are making this variety of clucks, peeps, trills, and croaks. And here’s a hint: when spring rains come, Virginia’s waters start jumping with these creatures.
SOUNDS - ~40 sec
If you guessed frogs or toads, you’re right! Those were the calls of nine frogs and two toads, part of Virginia’s 27 native species of these two groups of amphibians. As early as late January in the Commonwealth, some species—like the Wood Frog and Spring Peeper—move from overwintering habitats to temporary pools or other wet areas, where males use distinctive calls to attract females for breeding. As spring and summer progress, Virginia’s ponds, rivers, and other aquatic areas resonate with chorus frogs, tree frogs, pickerel frogs, leopard frogs, bullfrogs, green frogs, and several kinds of toads.
Whether or not the weather at the moment looks or feels like spring, frog and toad calls are sure signs of seasonal changes in the air, on the land, and in the water.
Thanks to the Virginia Department of Game and Inland Fisheries and to Lang Elliott for permission to use several of this week’s sounds.

Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment. Thanks to Ben Cosgrove for his version of “Shenandoah” to open and close the show. In Blacksburg, I’m Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.

If you’re interested in amphibians and particularly in frog calls, you might want to consider volunteering for the Virginia Frog and Toad Calling Survey, coordinated by the Virginia Department of Game and Inland Fisheries.

The Virginia program is part of the North American Amphibian Monitoring Program. These programs use the sensitivity of amphibians to water quality as a tool for assessing changes or threats to aquatic systems.
