As part of the Refugio oil spill that occurred in May 2015, several Brown Pelicans were cleaned and released with green bands, similar to the International Bird Rescue Center's blue-banded Brown Pelicans. Information on where to report banded birds is provided below. Please note that Oiled Wildlife Care Network (OWCN) accepts Green-banded sightings and the International Bird Rescue Center (IBRC) accepts sightings for both Blue-banded and green-banded Brown Pelican reports.

Green-banded Brown Pelicans can be reported at and selecting the "green banded pelicans" tab, or by this link. Sightings of these birds will help us learn how well these birds survive after being oiled and cleaned.

Green and Blue-banded Brown Pelicans can be reported to the IBRC at the following link

Our next meeting will be Monday, October 19th at the Caspar Community Center 15051 Caspar Rd, Caspar, CA 95420 at 7PM. Robert Lewis will speak on A Bird's Rainbow His website

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.

The pigment that creates the yellow color in King Penguins is still undefined. Saffron Toucanet's yellow feathers are colored by carotenes in the food it eats. The Red-headed Barbet operates a chemical plant in its body to convert yellow carotenes to red pigments.

Pigments in bird feathers include melanins, carotenes, and a number of less known dyes. But all color doesn't come from pigments - some originates from the physical structure of the feather, which in birds like hummingbirds is designed to reflect only one color back toward the target - perhaps another hummingbird, or maybe the photographer. Birds eyes are different than ours, and many birds are able to see into the ultraviolet, providing them with color information we can't see. Color in birds helps them choose healthy mates, recognize immature and adults of their species, differentiate males and females, advertise their presence and defend their territory, or camouflage themselves to hide from predators.

Bob trained as a chemist and worked for Chevron for 33 years. He's taught birding classes in the Bay Area for over 20 years, and is the chair of Golden Gate Audubon's Adult Education Committee. Currently he's co-teaching a popular Master Birding class at the SF Academy of Sciences with Jack Dumbacher and Eddie Bartley, and will be teaching "Birds of the Bay Area" for Golden Gate Audubon this fall. He loves to travel and photograph birds, and has recently returned from a trip to SE Asia, chasing the brightly colored birds of that area. Bob has seen over 4500 of the world's bird species, and has photographed many of them.
