Field Trips

Golden Gate Audubon offers more than 150 field trips annually for birders of all levels. Our trips explore local areas from Golden Gate Park to the East Bay shoreline and hills, as well as such wildlife-rich destinations as California’s Central Valley and the Sierra Nevada.
Local trips are generally free except for any park entrance fees. Advance registration is required. For most trips, registration will open two weeks before the trip date and close a few days before the trip. We are currently limiting the size of most trips to allow for social distancing; no drop-ins, please.
See the calendar below (which you can also view as a list) for information on upcoming trips. Once registration opens for a trip, you will find a sign-up link on its information page.
We also sponsor trips to other parts of the U.S. and to international destinations, including Latin America, Africa, and Australia. See our Travel with GGAS page for upcoming travel opportunities.at

About our Field Trips
Our trips welcome birders of all skill levels, especially beginning birders. We encourage experienced birders to help the newcomers in the group. And beginners: Don’t be shy! We warmly invite you to identify yourself at the start of the walk so the leaders and more experienced birders can help you.

Cancellations: Heavy rain almost always cancels trips. Other cancellations may be posted on the GGAS-Chat discussion group, described below. If you’re uncertain about whether a trip has been cancelled, please contact the trip leader.
We invite your feedback on any aspect of our trips (leadership, venues, schedules). Send an email to Field Trip Coordinators Steve Lombardi at hotrock175@gmail.com or Christina Tarr at christina.tarr@gmail.com. For questions about individual trips, contact the leaders. If you cannot reach a leader, contact our office at 510.843.2222 or email hotrock175@gmail.com.
Summaries of field trips from 2004-2020 are available online in our Trip Report Archives. For more recent trip sightings, see eBird.

Oceanic Society

Grebe Courtship
Web: eyesofthewild.com

Seeking New Field Trip Leaders
If you’re a birder with favorite spots you’d like to share, consider joining our cadre of volunteer field trip leaders. It might sound a little scary (“Who, me? I can’t lead a field trip!”) but it’s really fun and quite easy.
We can provide training walks and mentors, help you write trip descriptions, and find background resources on the birding spots you love. You don’t need to be able to identify every bird: You’ll be successful by organizing an enjoyable walk at an interesting location.
If you’re interested (even if you’re maybe a little interested, but also a little nervous) contact Maureen Lahiff, Adult Education Committee chair, at 510.484.6529, MLahiff@aol.com or Field Trip Coordinator, Steve Lombardi at hotrock175@gmail.com.
