Tomales Bay winter shorebird count

December 4, 2023
- 1:00 pm
to 3:30 pm

Audubon Canyon Ranch will once again be conducting our regular series of six winter shorebird counts on Tomales Bay and we encourage experienced birders to join us.

Since 1989, we have monitored seasonal populations of shorebirds on Tomales Bay with the help of volunteer field observers. Three bay-wide counts are completed within each early-winter and late-winter census period; an additional bay-wide count is conducted each August and April to record peak numbers of fall and spring migrants. Data from the first count of the season (November 20) will be contributed to the Pacific Flyway Shorebird Survey.

Each count requires 60 to 90 minutes to complete; volunteers often allow for some extra time to get settled before the count begins. Volunteers should be able to identify shorebirds.
