Animal Aeroacoustics is the study of the sounds animals make when they fly. We integrate the fields of flight biomechanics, animal behavior and physical bioacoustics. Our research includes the physics of how aerodynamic sounds are produced, how they evolve, and what behavioral and ecological relevance they have. We also study the behavioral ecology and biomechanics of "athletic" courtship displays. All of these research interests interact in our studies of hummingbirds, which make fantastic sounds during their dynamic courtship displays. Other interests include owls, mosquitoes, bees, and the fun noises any other bird makes in flight.
