Who doesn’t love watching a bird sing his heart out to attract a mate? David Enstrom, a retired ornithologist with the Illinois Natural History Survey, will describe the way birds produce songs and colors and how they are used in displays, how bird perception differs from human perception, and what this means to our understanding of bird behavior. He will also touch on how the study of birds affected the history of evolutionary science and share some spectacular examples of avian displays.
