Flight-calling in Wood-Warblers (Parulidae): Does Species-Specific Behavior Drive Evolution of Calls?
Flight calls are poorly understood vocalizations given by migrating warblers (Parulidae) that are thought to maintain flock unity. Calls vary between species but the exact role in communication between and among species is unknown. I propose to understand the function of flight calls by aurally and visually recording warbler migration. I will test if calls function in communication between members of the same species or mixed species flocks.
