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.
Whether identifying flora and fauna in the field with a click or using it to record your own non-bird observations, iNaturalist is an invaluable new tool for nature lovers. Local birder/restorationist Jeff Skrentny will explain how to use the app and tell some of the tales behind his 11,000+ iNaturalist entries representing over 2,600 species of bird, insect, mammal and plant life.
