Xeno-canto

Online database of wildlife sounds

xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of bird calls and sounds of orthoptera and bats. Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. All the recordings are published under one of the Creative Commons licenses, including some with open licences. Each recording on the website is accompanied by a spectrogram and location data on a map displaying geographical variation.
