Song (and call) dialects
From page 68 in the book.
A road trip through white-throated sparrow song dialects. Take a road trip, slowly, with the windows open, through white-throated sparrow country, listening carefully to their songs. Start in the East and head west, or reverse the direction. Stop and take a listening sample every 100 miles or so. How far have those western doublets encroached on the eastern oh sweet Canada triplet songs? It's a dynamic situation, exciting to track over time, to understand better the puzzling, rapid cultural changes in birdsong that can occur over widespread geographic areas.
