Decades of bird signals, songs digitized for scientific research
The world's largest scientific archive of animal signal recordings, the Macaulay Library of Natural Sounds, is partnering with other institutions to co-curate and digitize an enormous archive of animal audio and video recordings from the library's vaults. The analog material in the library's collection at the Cornell Lab of Ornithology includes recordings of mainly birds, but also frogs, fish and insects, going back a few decades. The collections are a bonanza for animal behaviorists, who use the archives to study birds and other animals from all over the world, including some that are now extinct, such as the imperial woodpecker. Accessible digital audio recordings of animal signals will make it easier for researchers to investigate a host of scientific questions, including what can scientists learn about the responses of animals to anthropogenic noise and other human activities. By providing a useful co-curation system and encouraging collection of recordings along with physical specimens, this project is expected to transform the way researchers collect and use biological specimens in the future.
