Many birds are brightly colored, while 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 Lewis 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.
Bob Lewis trained as a chemist and worked for Chevron for 33 years. He's taught birding classes over 20 years in the Bay Area.
