San Francisco Bay, the largest and one of the most important estuaries along the Pacific Flyway, is right in our own backyard. Join us as we cruise from Berkeley toward the Golden Gate Bridge and north into San Pablo Bay, hugging the shorelines and waters that are home to thousands of wintering birds. We will pass ten islands, under two bridges, and up two creeks in four counties in search of migrating and resident waterfowl, shore-birds and marine mammals. This trip offers water bird and marine mammal viewing in stunning locations, many of which can only be seen by boat. In addition to the many ducks, loons, pelicans and gulls that come into the Bay for the winter, we can also expect to see resident cormorants, grebes, terns, and murres.

Dress in layers, and bring liquids and lunch. All participants must be fully vaccinated. Please bring a mask for any time spent inside the cabin.

The trip costs $120. Limited to 25 people. 

Registered participants will receive directions to the Berkeley Marina and other instructions prior to the trip.

Mid-November is a surprisingly active time for migrants at this Marin Headlands location, as we search for scarcer late fall migrants including winter wildfowl, loons, grebes and passerine migrants. As always, the weather will determine the focus of our search on the day.  With this ‘hotspot’ producing some memorable Marin rarities in recent Novembers, including Tricolored Heron, Scaly-breasted Munia and Rusty Blackbird, almost anything is possible! We will begin the morning with a sea watch (most productive when onshore winds are blowing) and/or visible migration watch (most productive when offshore winds are blowing) at 7:30 AM. Those arriving later may join us at 8:30 AM for a circuit of the lagoon. 

Registration for this trip will be open starting on November 8 at 8:00 AM on the MAS website Field Trips page. There is a limit of 12 participants for this trip. There will not be a waiting list. No drop-ins, please. All participants must be fully vaccinated.

DIRECTIONS: Head south on Hwy 101 and take the last Sausalito exit just before the Golden Gate Bridge. At the exit stop sign, turn right and go under the freeway, then follow the road down to the left. Within 300 feet turn left at the sign to the Marin Headlands (This is the only available left turn before you begin the descent into Sausalito). You should see the tunnel with the five-minute light. Proceed through the tunnel on Bunker Road to the Rodeo Lagoon Parking Lot at the end and meet by the bridge over the channel to the beach.
