About this sound
Each year, Mammoth Hot Springs fills with elk (Cervus elaphus) that congregate for the annual breeding season. Listen carefully to this recording: Along with the screechy calls of Great horned owls (Bubo virginianus), you'll hear several bull elk calling to each other, their distinctive bugles ringing out of the crisp, autumn night.
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.
