Birdsong was a temporary radio channel[1] which used to broadcast on national digital radio in the United Kingdom. The transmission consisted of a continuously looping recording of bird song. It was available via the Digital One DAB network. The recording was also available via the Digital One website[1] until Autumn 2009 and the RadioBirdsong website.[2][3] Originally starting out as a test signal on analogue radio in 1992[4] and then later broadcast on digital radio from 2003 to 2005, the channel gained regular listeners, who complained when it was taken off-air.[5] In 2008–2009, the broadcast again existed as a 'filler' transmission until a commercially operated radio station, Amazing Radio, replaced it on 1 June 2009.[6][7] On 27 December 2019, the channel returned to digital radio once again in the Portsmouth area.
