Welcome to the Marin Audubon Society

About Us

The Marin Audubon Society was established in 1956 as part of the effort to prevent development of houses on Richardson Bay tidelands. Our Mission is “To conserve and restore natural ecosystems, focusing on birds, other wildlife, and their habitats, for the benefit of humanity and the Earth’s biological diversity.” More »

For more than 60 years Marin Audubon has worked to protect wildlife habitat in Marin, sometimes stepping in to buy land that is slated for development.

MAS also provides its members and the public many opportunities to experience the birdlife and nature of Marin County and beyond through Field Trips and Events, our monthly MAS newsletter The Rail, and three annual Marin Christmas Bird Counts.

Field Trips

Mar 02

The Ponds at Las Gallinas Sanitary District (LGVSD) – San Rafael

MARCH 2 @ 8:30 AM - 11:30 AM

Thursday, March 2, 2023
8:30 to 11:30 AM
Birding with Sande and Bob Chilvers

All participants are welcome to join this trip. No registration required.

Beginning birders are especially welcome on the first Thursday of each month for a leisurely walk around the Las Gallinas ponds. Join our friendly leaders as we search for waterfowl, waders, songbirds, raptors, and shorebirds.

Bird enthusiasts of all levels help each other to find and identify the birds, and there are usually several experienced birders to assist. You don’t even have to arrive on time because we spend the first 30 to 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 Rd toward McInnis Park. Turn left immediately after crossing the railroad tracks and drive about 0.5 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.

Birding in Marin – Mt Tam and Corte Madera Marshes

MARCH 4 @ 8:30 AM - 3:00 PM

Birding in Marin, Season 8 – Trip 3
Saturday, March 4, 2023
8:30 AM to mid-afternoon
Birding with Jim White and Bob Battagin 

CLICK HERE to sign up for this field trip

Registration opens Wednesday, February 22 at 8 AM. Trip limit is 15 fully vaccinated participants. No drop-ins, please. 

Mount Tamalpais, rising like an icon above Marin, hosts some birds uncommonly seen in the rest of the county such as Pileated WoodpeckerRed-breasted NuthatchPurple FinchRed Crossbill, and in the winter, 1 or 2 Townsend’s Solitaire.

About twenty years ago our friend Dave MacKenzie discovered a TOSO feeding on mistletoe berries in some Sargent Cypress trees along the trail to Barth’s retreat and the bird or its children have returned every year since! But the trail, built by the CCC, (California Conservation Corp), back in the 1930s has not withstood the test of time quite as well. So, if you are up for a vigorous though short (3.5 miles) hike, join us to see what we can find.

After our lunch break back at Rock Springs with fine picnic tables and a restroom, we intend to drive down to sea level to look at the Corte Madera marshes. This area is very birdy, so depending on the tidal height, we expect to see a lot of birds there. Wintering shorebirds are gearing up for the return to their arctic nesting grounds, so we may be able to see how Black-bellied Plovers got their name. As the shorebirds molt into their breeding plumage, if we are diligent, we might even be able to tell the two Dowitcher species apart.

DIRECTIONS: Meet at Rock Springs at 8:30 a.m. From Hwy 1 in Stinson Beach or up 3.3 miles from Tam Junction, take Panoramic Dr to its crest then go uphill 1 mile on Pantoll Rd to the Rock Springs parking lot.

Rodeo Lagoon – Marin Headlands

MARCH 8 @ 7:30 AM - 12:00 PM

Wednesday, March 8, 2023
7:30 AM to noon ** Please note this field trip starts at 7:30 AM not 8:00 AM
Birding with William Legge & David Wiechers 

CLICK HERE to sign up for this field trip

Registration opens February 26 at 8:00 AM. Trip limit is 15. No drop-ins. please.

With early spring migration underway will be looking out for migrant wildfowl, grebes, loons, gulls, and passerines. As usual, the weather will dictate our focus with onshore northwest winds ideal for spring sea watches, while offshore easterly winds promise a good selection of passerine migrants. Join us for a Sea Watch at 7:30 AM or arrive later at 8:30 AM for a circuit of the lagoon.

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 signal 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.

A World on the Wing: The Global Odyssey of Migratory Birds

FEBRUARY 16 @ 6:00 PM - 8:00 PM

Thursday February 16th, 2023
Start Time:
6:00 PM
Speaker: Scott Weidensaul

This program is a Zoom presentation of Golden Gate Audubon Society, co-sponsored by Marin Audubon Society and others.
Please use THIS LINK the night of the Speaker Series. Password: 066785

Scientists continue to make astounding discoveries about the navigational and physiological feats that enable migratory birds to cross immense oceans, fly above the highest mountains, go weeks without sleep or remain in unbroken flight for months at a stretch. Scott Weidensaul, author of A World on the Wing (2021), takes us around the globe — to the shores of the Yellow Sea in China, and the remote mountains of northeastern India where tribal villages saved the greatest gathering of falcons on the planet, to learn how people are fighting to understand and save the world’s great bird migrations. 

Scott Weidensaul’s field research focuses on bird migration. He is a co-director of Project Owlnet, studying owl migration, and is a founder of the Critical Connections project, which is tracking the migration of birds that breed on National Park lands in Alaska. He co-founded the Northeast Motus Collaboration, which is creating a network of telemetry receivers to track the movements of bats, insects and small birds.

Speaker Series

Marin Audubon hosts a monthly Speaker Series on the second Thursday of the month, from September through June. The programs feature lectures on birds, mammals, and other natural history topics and are given by speakers who are experts in their field. Programs are free and open to the public. More »

Conservation

Maybe you have had the experience of passing a favorite spot only to be disappointed at the sight of bulldozers and “progress” at work. Maybe you’ve lamented about the inevitability of it all, enraged that it occurred, or maybe you are frustrated about loss of wildlife, trees, habitats and/or climate change. If you have, then it is time to think about Marin Audubon’s Conservation Committee. More »

Volunteer

MAS offers many opportunities to meet fellow members and to support our environmental protection and conservation efforts. Would you like to serve on the Board of Directors? Help with the Christmas Bird Count? Help with restoration projects? Join the MAS Conservation Committee? Help with the annual MAS/ACR Mother’s Day BBQ event in May? These are just a few of the many ways that you can pursue your interests or share your talents. More »

Properties

Consistent with our mission “To conserve and restore natural ecosystems, focusing on birds, other wildlife, and their habitats, for the benefit of humanity and the earth’s biological diversity” the Marin Audubon Society has been acquiring properties in Marin County with current or restorable habitats. Some properties are restored and turned over to a public agency and some properties remain in the ownership of the Marin Audubon Society. More »

Stewardship/Restoration

Marin Audubon plans and implements habitat restoration and enhancement projects, maintains habitats, and monitors activities on properties it owns. Restorations focus on recreating tidal marshes and associated transition zone and upland habitats. Restorations usually involve moving dirt fill or levees to lower elevations or remove obstructions(levees) to tidal waters and are usually undertaken with grants from federal, state or private foundations.

MAS BOARD OPPORTUNITY

Marin Audubon has extensive programs, has made impressive accomplishments preserving and restoring habitats, and conducts volunteer work days to maintain habitats we own. Our programs include conservation to protect our environment, the Breeding Bird Atlas, field trips to see and learn about birds, and monthly illustrated talks about birds and natural history.

At this critical time when climate change threatens birds, habitats and ourselves, a strong and involved  board of directors is even more important to help us deal with these issues locally. We depend on volunteers, including members of our Board, to plan and oversee our programs. To find out more about our Board, and other volunteer opportunities, and how you can help, please contact a member of our Nominating Committee:
