Thursday, February 1, 2018: A Bird's Rainbow - Bob Lewis
Birding Information: Thousands of houses currently proposed for development over 4-square miles (about 2,800 acres) of south Antioch would impact beautiful hills, the Sand Creek riparian corridor and endangered species habitat. Save Mount Diablo Land Use Manager Juan Pablo Galván will talk about what’s happening and how MD Audubon members can be part of grassroots advocacy efforts that will protect this important area.
A Bird's Rainbow - Bob Lewis
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. Photos below by Bob Lewis.
Bob Lewis trained as a chemist and worked for Chevron 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. Currently he’s teaching Birds of the Bay Area with Rusty Scalf, and next month will begin the fifth class of Master Birding at the California Academy of Science. He loves to travel and photograph birds, and last year chased brightly colored birds in Cuba, the Dominican Republic and Colombia.
