Bird song playback as a tool should exist only to help the cause of ornithology and science, not to help photographers become social media sensations, or for birdwatchers to win the 'big year'.
Are you a birder/photographer who treats birds with respect by not using playback? Now you can proudly wear your 'No to Playback' badges and t-shirts and let your peers know that you're an ethical birder.
