🐸 Smol frog, big sound. Have you heard the nightly chorus come alive, signalling the first signs of spring? Spring peepers are one of the first frogs heard in the transition from winter to spring. Want to practice your frog call ID skills? National wildlife refuges are known for wetlands and are a good place to listen for frogs any time of day, especially at dusk. Just be sure to check local regulations for open and closed hours. Spring peeper calling by Megan Seymore/USFWS | U.S. Fish and Wild
