Rodeo Lagoon – Marin Headlands
Join William and David for this third fall migration field trip at Rodeo Lagoon. This is their long-time “patch,” which never seems to disappoint birders with daily variations in species and a good chance of an unusual sighting. On this trip, our group will be targeting Parasitic Jaeger, migrating shorebirds and scarcer migrant passerines. We will begin the morning with a Sea Watch from Rodeo Beach at 7:30 AM. Those arriving later may join us at 8:00 AM for a circuit of the lagoon. READ MORE
Vaux’s Swifts at McNear Brick and Block – San Rafael
Join other MAS members for an evening opportunity to witness Vaux’s Swifts during their fall migration through Marin, which occurs in September and October. Dan McNear of McNear Brick & Block has kindly allowed Marin Audubon to access this remarkable site where decommissioned smokestacks provide an important communal roosting place for the swifts.
