THEY’RE BACK! The Spring Peepers are out of hibernation and back to work peeping in the swamps and singing their chorus on warm spring nights. The great chorus of peeping is generated by male Spring Peepers which are only about the size of a thumbnail. It is amazing that such a small frog can make such a big noise. It’s fun to stop alongside of a marshy area and listen to them sing even though you can hear them when you are driving by. To hear what they sound like you can play this audio clip. On cooler nights they quiet down and when summer arrives they head into the woods to live.
