About this sound
Steller's Jay call from two birds recorded in the Twin Owls area of Rocky Mountain National Park. Note that an American Robin, Clark's Nutcracker, Broad-tailed Hummingbird and Violet-green Swallow can also be heard in the recording.
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.
