Lay Summary Bills not only influence what birds eat – they can also influence what birds sound like. Island Scrub-Jays, which only occur on one island, have bills that are adapted to food in their local habitat. Here, we report that females with longer, shallower bills (characteristic of pine habitats) produce calls that differ from females with shorter, deeper bills (characteristic of oak habitats), an association that may have aided the evolution of different bills within the island.
