About this sound
Rattlesnakes use the rattles on their tails to warn those who get too close. When you hear this sound, back away! Rattlesnakes are not aggressive and only want to be left alone.
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.
