Frogs Report the FIRST Frogs you hear singing this spring to Journey North! Spring makes itself known not only by new sights but also through new sounds. One unmistakable spring sound is the croaking and calling of frogs, which will soon raise a chorus in the wetlands, stream banks, and woodlands across North America. This year, we ask your help in LISTENING for the arrival of spring. Four frog species, all known for early spring singing, will be included in this study. We're eager to hear from you--as soon as you hear from them. Listen for these Frogs Find your home town on the maps below and listen for the frog species that live near you.
