About this sound
Wood frog calls combine to form a dense chorus. Recorded at the Wonder Lake Frog Ponds site.
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.
