Change Your Tune

In a recent report in Current Biology, researchers published findings that the white-throated sparrow’s birdsong, which originally sounded like “Old Sam Peabody-Peabody-Peabody,” had evolved over the last fifty years to sound more like “Old Sam Peabuh-Peabuh-Peabuh-Peabuh.” In the New York Times, Ken Otter, a professor at the University of Northern British Columbia, says this unexpected shift related to the migration patterns of the sparrow is “kind of like an Australian person coming to New York, and all the New Yorkers start suddenly deciding to adopt an Australian accent.” Write a story about a character who has moved to a new city, and whose behavior has an outsize influence on the town’s citizens. Does the change happen gradually, going largely unnoticed for a long period of time, or does your character set off a rapid-fire chain reaction of transformations?
