Santa Clara Valley Audubon Society Speaker Series: Ivan Phillipsen - Livestream

One of the things we love most about birds is their wild array of plumage colors and patterns. Where does all that color come from? In this presentation, you’ll learn how pigments and microscopic structures in feathers create the kaleidoscope of beauty we find in the avian world. We’ll cover topics such as iridescence, molting and feather wear, the evolution of feather color, and the functions of feather colors. 

Ivan Phillipsen is a professional naturalist guide with a background in scientific research.
