In many areas of North America, spring would not be the same without the well-known song of the Common Yellowthroat, broadcast by the male from near a wet ditch or a bog. New bioacoustic analyses by Rachel Bolus reveal that even the song of this ubiquitous warbler shows distinctive and predictable variations across geographic regions and among genetically recognized subspecies. Morphology also matters, with the pitch of the song decreasing with longer bills. This research highlights the potential for new discoveries using publicly available databases, including the Macaulay Library at Cornell University and the Borror Laboratory of Bioacoustics at The Ohio State University.
