Hey Kids,
It's your pal, Thorndyke, and today I’ve got some ribbit-ing information to share with you.
Have you ever heard frogs singing at night? Croak! Peep! Trill! Those sounds aren’t just music. They’re important clues. That’s where FrogWatch USA comes in!
FrogWatch USA is a special program where people listen for frogs and toads to help scientists learn how they’re doing in nature. When frogs are healthy, it usually means the environment is healthy too.
FrogWatch USA is managed by the Akron Zoo in Ohio, but zoos in several states offer training in how to become a FrogWatch volunteer. However, you don't have to live in Ohio or complete training to join the fun. Kids and families can look and listen for frogs wherever they live—near a pond, a creek, a wet park or even a puddly spot after rain.
You don’t need to catch frogs or touch them at all. Just listen carefully and notice what you hear. Different frogs make different sounds, and learning them is like learning a secret language of nature. How cool is that?
You can try to identify particular Michigan frogs (and toads) by their calls, using online recordings at Froggyvoice, the Michigan Department of Natural Resources’ downloadable collection of recorded calls or FrogWatch USA’s YouTube playlist of frog and toad calls.
So grab a grown-up, step outside and use your bear-sized listening ears (or kid-sized ones). Whether you live in a big city or a quiet town, frogs might be closer than you think. And when you listen, you’re learning about nature—one croak at a time.
When you're not listening for frogs, you could listen to or read one of these frog-related books.

Frogness by Sarah Nelson – Sammy and Chocolate tiptoe into the marsh behind their house in search of frogs. They can hear frogs everywhere, but they can’t spot even one. It’s only after they stop looking, flop onto the grass and fade into frogness—no thinking, just being—that frogs come flying.
