The Umpqua Valley Audubon Society and the Roseburg Public Library invite the public to “A Bird’s Rainbow”, presented by scientist, birder and teacher Bob Lewis.

The event will be on Wednesday, February 11th at 6:30 p.m. and will be held at the library on Northeast Diamond Lake Boulevard.

A city release said many birds are brightly colored. Others use patterned feathers for camouflage. Often bird watchers wonder how the colors originate, what the difference is between colors from pigments and physical colors and what colors indicate in birds. Lewis will unravel some of the mysteries of color in birds with a little chemistry, a little bit of physics, and a lot of brightly colored slides.

Lewis trained as a chemist and worked in the energy field for 33 years. He has taught birding classes in the San Francisco Bay Area for more than 25 years and served as the chair of the Golden Gate Bird Alliance’s Adult Education Committee. He has received numerous awards due to his knowledge.

Lewis loves to travel and photograph birds and has chased birds in more than 60 countries. His life list contains more than 5,500 species.
