An otherwise peaceful pastime has been roiled by conflict as digital field guides, and the song recordings they include, have made birding easily accessible for anyone with a smartphone and, sometimes, a portable speaker. In a hobby where reward has come from years of quietly, patiently waiting outdoors and diligently studying technical tomes, there is deep resentment of birders who are relying on these easy-to-use—or abuse—apps.
