About this sound
Frogs calling recorded at vernal pond P31, near Province Lands Road, the night of April 28, 2013.
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.
