Tweet of the Day is a series of fascinating stories about British birds inspired by their calls and songs.

David Attenborough presents the third of four recordings marking Dawn Chorus Day: a dawn chorus from the marshes of North Warren in Suffolk. On clear moonlit nights the chorus can be an almost continuous chatter and includes reed and sedge warblers, reed bunting and even a bittern, with its booming, foghorn-like call.
