Richard K. Simpson - Animal Behavior Ph.D. Candidate

Graduate and Professional Student Association Assembly Member - School of Life Sciences - Arizona State University

Rick Simpson is a comparative behavioral ecologist interested in animal communication, signal diversity, and visual ecology.  His research focuses on understanding why animals use multiple signals to communicate and how such a diversity in animal signals evolved. He is currently a 5th year Animal Behavior Ph.D. candidate at Arizona State University, where he is studying the evolution of hummingbird coloration and courtship displays. Hummingbirds showcase some of the most brilliant colors in the animal kingdom and possess almost every color under the rainbow. These colors are primarily iridescent meaning they are angle-dependent structurally based colors. The angle dependence of iridescent coloration allows hummingbirds to drastically change their appearance through their courtship displays, where they can change how they position and orient themselves relative to the sun and female they are courting. Rick is working to understand how iridescent coloration and behavioral displays co-evolved with each other and the environment. While at the ranch he is focusing on black-chinned hummingbirds.
