Birding in Marin Third Saturday Field Trip Series:  Jim White and Bob Battagin have graciously offered to lead a trip for Marin Audubon on the third Saturday of every month for 12 months. These trips are included in the list below. Click here for the complete list.

Shollenberger Park
Location: Petaluma
Trip Leader(s): Peter Colasanti
Host: Jane Medley,, 559-760-1551
Start Date: Saturday, December 9, 2017
Start Time: 8:30 AM
End Time: 1:00 PM
Description: With over 230 species recorded, Shollenberger Park is one of the major birding hotspots in the North Bay. Over half those birds are possible in early December. Let’s spend a morning watching winter birds before it turns cold. If time and interest permits, we may extend to Ellis Creek. Heavy rain cancels.

Directions: Going north on Hwy 101 from Marin, take the second Petaluma exit, which is Route 116 (Lakeville Hwy). Go east about one mile to South McDowell Blvd (4th traffic light) and turn right. Take the third right on Cader Lane and park in the lot at the end.

Richardson Bay
Location: Richardson Bay Audubon Center in Tiburon
Trip Leader(s): Bob Hinz
Host: Jane Medley,, 559-760-1551
Start Date: Monday, December 11, 2017
Start Time: 9:00 AM
End Time: 12:00 PM
Description: We'll start with a walk through the Richardson Bay Audubon Center property to the "back beach" where with scopes we can see the eastern shores of the islands as well as the bay. Then it's off to the cove at the end of the bay where we may get close looks at a number of shorebird and waterbird species. Finally, we will walk along the path to Harbor Cove Way for a closer look at Pickleweed Island. Heavy rain cancels.

Directions: The Richardson Bay Audubon Center is at 376 Greenwood Beach Road. Take the Tiburon Blvd. exit from Highway 101 and drive about 0.8 mile to Greenwood Cove Road. Turn right at the traffic light toward the Audubon Center, which is about 0.5 mile farther.

The Ponds at Las Gallinas
Location: Las Gallinas, San Rafael
Trip Leader(s): Sande & Bob Chilvers
Host: Jane Medley,, 559-760-1551
Start Date: Thursday, January 4, 2018
Start Time: 8:30 AM
End Time: 12:00 PM
Description: Beginning birders are especially welcome on the first Thursday of each month for a leisurely walk around the Las Gallinas ponds. Join our skilled leaders as we search for waterfowl, waders, songbirds, raptors, and shorebirds. Wintering waterfowl have been arriving and provide interesting weekly sightings. Other uncommon species arrive unexpectedly such as the Loggerhead Shrike and Merlin observed by our November field trip participants.

We welcome bird enthusiasts of all levels. We all help each other to find and identify the birds, so come assist in our search. You don't even have to arrive on time because we spend the first 30-60 minutes studying the birds around the first pond and the group is easy to find. Heavy rain cancels.

Directions: From Hwy 101, exit at Smith Ranch Rd. Drive east on Smith Ranch Road toward McInnis Park. Turn left immediately after crossing the railroad tracks and drive about .5 mile through the LGVSD gates and into the parking lot at the end of the road. Meet the group by the bridge just past the parking lot. There is an outhouse in the parking area for public use or you can use the bathrooms at nearby McInnis Park.

Note the earlier starting time: 8:30 am

Sacramento Delta Boat Trip - Marin Audubon Members Only. Online Signups Begin December 11, 2017
Location: Boat leaves from and returns to the Antioch Marina
Trip Leader(s): David Wimpfheimer
Host: Jane Medley,, 559-760-1551
Start Date: Sunday, February 4, 2018
Start Time: 8:15 AM
End Time: 4:30 PM
Description: Join us aboard Dolphin Charters' River Dolphin for a wonderful day of exploring the richness of the California Delta with naturalist David Wimpfheimer as our guide. Ronn Patterson, a Bay Area historian, naturalist, and owner of Dolphin Charters, will be our captain. The boat is very comfortable and the outer decks provide views over the levees of the amazing array of birds found in the Delta during the winter. This rich area hosts a wide variety of raptors including Swainson's Hawks, Peregrine Falcons, and Great Horned Owls. Large numbers of shorebirds, Sandhill Cranes, Tundra Swans, Snow, Canada and White-fronted Geese, ducks, as well as gulls, terns, bitterns and passerines make the cruise a highlight for birders. Uncommon mammals such as beaver, river otter, and mink often add interest to the cruise. We also will learn about the history, ecology and politics of the levees and the Delta as we travel through its meandering channels.

Given that our boat trip is limited to just 25 participants, this trip is limited to Marin Audubon Society "Members Only" at a cost of $105. Our "Members Only" field trips are limited to chapter-supporting members of Marin Audubon Society (MAS). A membership with National Audubon Society does not qualify for participation in MAS "Members Only" field trips. Our "Members Only" field trips are a specific benefit we provide to MAS chapter supporting members for their support of Marin Audubon and the work MAS undertakes in protecting and managing local habitats for the benefit of Marin's resident and migratory birds.

Registration and payment for the trip will begin on December 11, 2017. Register at (For Non-MAS members, we invite you to join MAS at to participate in this trip.)

We recommend booking your space asap as our boat trips frequently sell out quickly. Include the name, email address, and contact phone number of each participant. Those confirmed on the trip will receive directions to the Antioch Marina and other instructions prior to the trip.
