Male birds typically sing the same tunes as the rest of their species because an unrecognizable song defeats the two primary reasons for their crooning — to establish and defend their territory and to attract mates. While the songs, which are passed down from generation to generation, may vary slightly by region, any new compositions are typically limited to the local environment. However, for reasons unknown to scientists, white-throated sparrows across Canada are abandoning their classic song for a catchy new tune "written" by their peers in British Columbia.
