Have you ever heard this sound? 🐸 That’s an American green tree frog (Hyla cinerea). These small and bright amphibians make noise from April through September in the Southeastern part of the U.S. Their geographic range stretches from as far north as Delaware, to the southeast tip of Florida, and even as far west as central Texas. This frog was seen in Congaree National Park in South Carolina. #FunFact: Green tree frogs are the state amphibian of #Louisiana and #Georgia. 📸: National Park Servic
