Should birdwatchers be able to use bird call apps? The question has caused a debate among birders.
The trouble is, there’s a slippery slope leading toward harassment of rare and/or endangered birds and, in the worst case, genuine interference with their nesting success. And the slope got a lot steeper with the proliferation of smartphones and birdsong apps … a number of bad things could happen when a birder plays a song to attract a bird. Momentarily distracted, the bird could be snatched up by a predatory hawk (this has been witnessed a number of times by distraught birders).
