Adirondack Peepers

This tiny frog fills the night air with its love song. The peeper has a vocal sac located by its throat, which expands and deflates like a balloon to create a short and distinct peeping sound. Only males have the ability to make this loud high-pitched noise, and they use it to attract mates. Peepers are nocturnal frogs making them heard but not seen. They are especially easy to hear due to their extremely loud mating call which gives them the name "peeper", but it is often hard to pinpoint the source of the sound, especially when many are peeping at once.
