On this St. Patrickâs Day, the pipes arenât all that are calling. So are frogs in local wetlands. Youâll hear them when the day is warm enough, especially the chirping of the tiny spring peepers and the washboard sound of chorus frogs.
Nolan Bielinski got to wondering if frogs and toads limit their calls when theyâre surrounded by city noises. So, for his doctoral research at the University of Illinois at Chicago, he took recorded sounds into wet areas in the Indiana Dunes National Park and around the Chicago area, according to the Great Lakes Research and Education Center.
