Animals use a dizzying array of sounds, smells, colors, dances, electrical fields and seismic vibrations to convince each other to mate. These elaborate courtship signals were a mystery until Darwin’s time—after proposing his theory of natural selection, Darwin was left with the question of how the flamboyant peacock could be shaped by the same process that makes the peahen so perfectly camouflaged. There is now strong support for Darwin’s answer to this question, the process he termed sexual selection, proposing that the courting sex must be elaborate because the courted sex demands it. But how can we study the conversations males and females in non-human animals have about mating? One way to do this is to participate, controlling one side of the conversation with a robot. Gail Patricelli will talk about using robotic females and other technology to study courtship behaviors in the greater sage-grouse, and how such research informs conservation of this iconic North American bird and its habitat.
Gail Patricelli is a professor in the Department of Evolution and Ecology at the University of California, Davis. Professor Patricelli and members of her lab study bioacoustics, the evolution of breeding behaviors, and the impacts of noise pollution on birds. She received her Bachelor’s degree in Biology and Art from Whitman College and PhD from the University of Maryland, and was a postdoctoral fellow at the Cornell University Lab of Ornithology.
