Nature 'Soundscapes' Recorded for Posterity

Oct. 6, 2008 -- Rattlesnakes aren't to be trifled with, but if you're trying to collect the sound of every creature in the West that slithers, hops, flies or flops, distance isn't a luxury you can afford.

"You get yourself in some strange situations," said Jeff Rice, a soft-spoken University of Utah research librarian who's trying to create the first comprehensive -- and free to the public -- archive of natural sounds in the West.

Minutes later he was squatting in the hills above Salt Lake City, training his lightweight parabolic microphone toward a Great Basin rattlesnake a few feet away.

The snake, caught by wildlife agents that day in a backyard, offered a few doubtful quiet moments. Finally, though, it let loose a long dry rattle, both eerie and fascinating, that unmistakably said "keep away."

"I knew he'd come through," Rice said, grinning like he'd been given a Christmas present.

The recording, reduced to a short clip, will be added to the Western Soundscape Archive, a Web-based sound clearinghouse headquartered at the university library.

Although it's just a year old, the site already has more than 800 recordings. The goal is to catalog the nearly 1,200 species of birds, mammals, reptiles and amphibians that roam 11 Western states. It will also feature "ambient soundscapes" from wild places across the region.

The sounds will be available to teachers, scientists and anyone else interested in hearing the odd murmurings of a sage grouse, javelina, Columbia spotted frog or mountain-dwelling moose.

The landscape recordings could also provide an important audio snapshot that could be used for comparison later when trying to understand how animals respond to encroaching subdivisions, oil and gas development, a warming climate, or other changes.
