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.

Register HERE for this field trip

Limit of 15 fully vaccinated participants for this trip. Registration opens on our TicketBud sight on September 25 at 8AM.

With large numbers of birds moving through the area this time of year, it’s sure to be an interesting outing with unusual sightings a definite possibility. We’ll start with a 30-40 minute visible migration and sea watch from Rodeo Beach hoping for Parasitic Jaegers as well as other passing goodies before undertaking an extended circuit of Rodeo Lagoon in the search for scarce migrants including early winter wildfowl, shorebirds and fall passerines. More than 60 species should be possible at this time of year. The morning will begin with a sea watch at 7:30 AM.

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.

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

Join old friends and meet new ones as we resume our regularly scheduled walks on the first Thursday of the month at Las Gallinas. Special thanks to Bob and Sande Chilvers
for volunteering once again to lead our monthly walks in search of waterfowl, waders, songbirds, raptors, and shorebirds. With fall migration underway, we are likely to spot some interesting species, so come assist in our search. 

We welcome bird enthusiasts of all levels. We all 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 30-60 minutes studying the birds around the first pond, and our group is easy to find. 

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.

Hummingbirds of California and Beyond

OCTOBER 13 @ 7:00 PM - 9:00 PM

Thursday, October 13 at 7:00 PM
Speaker: Bob Lewis
Free and open to the public.
Register for this speaker series program HERE

The story of hummingbird evolution starts about 50 million years ago, far from the lands they currently inhabit.  We’ll trace the history of their evolution and then briefly discuss relationships between the 9 tribes of living species. After reviewing California’s 7 most common species – all belonging to the Bee tribe, we’ll look at other North American species, and then examine representatives of the other tribes, mostly concentrated in South America. Finally, we’ll consider some conservation issues and end with a few words on hummingbird photography.  

Bob trained as a chemist and worked in the energy field for 33 years. He’s taught birding classes in the Bay Area for over 25 years and served as the chair of Golden Gate Audubon’s Adult Education Committee.  Bob was honored with American Birding Association’s Chandler Robbins Award for Education and Conservation in 2016. He loves to travel and has photographed and chased birds in over 40 countries. His life list is over 5000 species.

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:
