Frog calls in your backyard

While you are staying in one of Archbold’s cottages, was delighted to hear a chorus of frog calls each evening, one of the many special surprises visitors who spend the night on the station have the pleasure to experience. Complied here are WHO’s notes on each species’ individual call, along with photos of each species. Where available, a sound bite of each species’ call is also provided. Simply click on the species’ photo, and the audio recording will open in a pop-up window. Pay attention, and next time you hear a frog call in your backyard, you may be able to identify it!

Special thanks to AmphibiaWeb, which was used to compile all photos and recordings.
