About this sound
Boreal chorus frogs croak while Wilson's snipe use their wings to make their unique sound and sandhill cranes call out.
Why parks record sound
The NPS Natural Sounds and Night Skies Division monitors soundscapes in parks across the United States. Natural quiet is treated as a resource to protect, like clean air or dark skies: noise from aircraft, vehicles and machinery can mask animal communication and change the experience of a place.
