Winter is waterfowl season, with millions of ducks, geese and swans arriving in northern California. Our new “Duck, Duck, Goose… Loon?” class starts on Saturday November 24 and includes two Sunday field trips to San Francisco and the Sacramento Delta.

Learn to identify the nearly 30 species in the order Anseriformes (including ducks, geese, swans) that reside or overwinter in California, and learn about the evolutionary adaptations and life histories that distinguish them from other water birds like loons and grebes.

The class will take place from 9 am to 3 pm on November 24 at the new EcoCenter at Heron’s Head Park in San Francisco. Field trips will take place on Sunday November 25 (9 am to noon in San Francisco) and Sunday December 2 (10 am to 4 pm, to the Cosumnes River Preserve in the Sacramento Delta).

Class size is limited to 20. Fee: $60 for GGBA members, $75 for non-members. For more information, see the Classes page on our web site. To sign up, please call the GGBA office at (510) 843-2222.
