Given little is known about the night flight calls of many East Asian species, it is perhaps not surprising that many calls recorded by the Beijing Nocturnal Bird Migration project remain unidentified. This page includes some of the calls for which an identification has not yet been reached. If you can help with any of these recordings, please use the contact form below or contact Terry via email on terry.townshend[at]gmail.com. Thank you in advance for any help provided.
