The world's largest archive of animal vocalizations and other nature sounds is now available online.
This resource for students, filmmakers, scientists and curious wildlife aficionados took archivists a dozen years to assemble and make ready for the web.
"In terms of speed and the breadth of material now accessible to anyone in the world, this is really revolutionary," audio curator Greg Budney said in a press release, describing the milestone just achieved by the Macaulay Library archive at the Cornell Lab of Ornithology.

"This is one of the greatest research and conservation resources at the Cornell Lab," added Budney. "And through its digitization, we've swung the doors open on it in a way that wasn't possible 10 or 20 years ago."
The collection goes way back to 1929. It contains nearly 150,000 digital audio recordings equaling more than 10 terabytes of data with a total run time of 7,513 hours. About 9,000 species are represented. Many are birds, but the collection also includes sounds of whales, elephants, frogs, primates and more.
