About this sound
Red-winged Blackbirds sing, hummingbirds buzz and Western Chorus Frogs chirp in this recording of the ambient sounds from Moraine Park in Rocky Mountain National Park. The recording began at 6:30 PM.
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.
