SUMMARY:NSAS November Speaker Series Presents: A Bird's Rainbow with Bob Lewis - Nov. 13th at 7:00 p.m.
DESCRIPTION:About the Presentation: Many birds are brightly colored\, others use patterned feathers for camouflage. How do these colors originate? What’s the difference between colors from pigments and physical colors? From Yellow Warblers to Anna’s Hummingbirds\, from Snow Geese to Brewer’s Blackbirds\, each species makes unique use of the feather colors it possesses. What do the colors indicate to other birds? And do birds see the same colors we do? Bob will unravel some of the mysteries of color in birds with a little chemistry\, a bit of physics\, and a lot of brightly colored slides. \nAbout the Presenter: Bob trained as a chemist and worked in the energy field for 33 years. He’s taught birding classes in the Bay Area for over 25 years and served as the chair of Golden Gate Audubon’s Adult Education Committee. He’s a frequent speaker on birds at libraries and bird groups. Bob was honored with American Birding Association’s Chandler Robbins Award for Education and Conservation in 2016\, and Golden Gate Audubon’s Paul Covel Education Award in 2010 and 2017. He was one of the founders of the Master Birding Class held at the SF Academy of Science. He loves to travel and photograph birds and has chased birds in over 60 countries. His life list is over 5500 species.
