Emeritus Psychology

Dr. Leger joined the faculty in 1980. He received his Ph.D. in biological psychology from the University of California, Davis. He teaches biopsychology, learning and motivation and physiological psychology. Dr. Leger's research interests include, from most specific to most general: bird song, animal communication, animal behavior, evolutionary psychology, and biological bases of behavior. He is currently investigating bird song and animal anti-predator behavior. Dr. Leger is one of the core faculty in the Nebraska Behavioral Biology Group(NBBG).
