A healthy happy New Year to you all. Bob and I are pleased to share the bird rich Stinson Beach / Bolinas birding area with you. Coupled with non freezing winter weather and many diverse habitats the CBC, Southern Marin Christmas Bird Counts, show this to be most specie rich, birdiest, area in Southern Marin county. These habitats include the ocean, beaches, rocky shores, a large lagoon with acres of mudflats, Douglas Fir and Redwood forests, Alder riparian, parking lots, residential and more. The CBC data show an average of over 125 specie winter in this area. Plus, many of these birds, like ducks, gulls and shorebirds, are rather easy to see as they float about on the water or walk along the open shores. Can we find 100 species today?
Thanks can be given today to the founders of Marin Audubon and some conservation minded elders for the parks, open space, public access, and wildlife habitats in much of the country and around Bolinas Lagoon. Dr Martin Griffith was instrumental in saving Bolinas harbor from a hotel and yacht club destination and he is commemorated at the heron and egret rookery that we will pass along the east side of the lagoon.
So start your year list if you haven’t already. Bob is adept with ebird but he is recovering from hip replacement surgery. We strive to help all of our participants to see or hear all of the birds that we encounter but that is a goal not quite a reality. Let’s go birding!
Meet at 8:30 at the Stinson/Bolinas School on Highway 1

Recent headlines about global insect declines and three billion fewer birds in North America are a bleak reality check about how ineffective our current landscape designs have been at sustaining the plants and animals that sustain us. To create landscapes that enhance local ecosystems rather than degrade them, we must 1 remove the invasives on our property and 2) add the native plant communities that sustain food webs, sequester carbon, maintain diverse native bee communities, and manage our watersheds. If we do this in half of the area now in lawn, we can create Homegrown National Park, a 20 million acre network of viable habitats that will provide vital corridors connecting the few natural areas that remain. This approach to conservation empowers everyone to play a significant role in the future of the natural world.
Doug Tallamy is the T. A. Baker Professor of Agriculture in the Department of Entomology and Wildlife Ecology at the University of Delaware, where he has authored 106 research publications and has taught insect related courses for 41 years. Chief among his research goals is to better understand the many ways insects interact with plants and how such interactions determine the diversity of animal communities. His books include Bringing Nature Home, The Living Landscape, co-authored with Rick Darke, Nature’s Best Hope, a New York Times Best Seller, The Nature of Oaks, winner of the American Horticultural Society’s 2022 book award. In 2021 he co-founded Homegrown National Park with Michelle Alfandari. His awards include recognition from The Garden Writers Association, Audubon, The National Wildlife Federation, Allegheny College, The Garden Club of America and The American Horticultural Association.

The Ponds at Las Gallinas Sanitary District (LGVSD) - San Rafael
2023-02-02 08:30 - 11:30
Thursday, February 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.

Birding in Marin - Sausalito and Tiburon
2023-02-04 08:30 - 15:00
Season 8, Trip 2
Saturday, February 4, 2023
8:30 AM to mid afternoon
Birding with Jim White and Bob Battagin
Register HERE for this field trip
Registration opens Wednesday, January 25 at 8 AM. Trip limit is 15 fully vaccinated participants. No drop-ins, please.
We are going to explore the bay from the Sausalito waterfront to the Golden Gate and Richardson’s Bay around to Strawberry Point and on to Blacky’s pasture in Tiburon. Many ducks, loons and grebes winter on the bay waters and we may compare looks at similar species like Eared and Horned or Clark’s and Western Grebes, of Red-throated, Pacific and Common Loons or Greater and Lesser Scaup. We are likely to find some shorebirds too, perhaps a Spotted Sandpiper or a rather rare Wandering Tattler.
Herring runs happen around this time of year and if we are lucky they will still be numerous. Herring deposit large numbers of eggs on eelgrass, which water birds, especially gulls, love to feast on. Although the roe, are fancied by some diners and there is a purse seining fleet hungry for profit, the Department of Fish and Wildlife is trying to maintain a sustainable catch. Last year near this time I think that 10 species of gulls were located. So brush up on your gull IDs and join Bob and I along the shore.
DIRECTIONS: Meet at the east end of Harbor Drive. Handicap Accessible. We will park where the birding is close, near level and smooth. Thanks to enlightened development planning, Harbor Drive and the rather posh Strawberry spit have fine public shoreline paths.

A World on the Wing: The Global Odyssey of Migratory Birds
2023-02-16 18:00 - 20:00
Thursday February 16th, 2023

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.

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 Woodpecker, Red-breasted Nuthatch, Purple Finch, Red 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.

Mountain Lions in California are fragmented into subpopulations by roads and development. The Bay Area populations to the north and south of San Francisco are separated from each other and are separated from others further south and east by roads, development, and agriculture. Those to the north are affected by increasing road traffic, agricultural conversions for the wine industry, and other factors. Dr. Vickers will discuss the state of current knowledge, legal status, and ongoing research and mitigation efforts that are focused on these populations.
Dr. Winston Vickers is a wildlife research veterinarian with the University of California-Davis Wildlife Health Center (WHC). He has been studying mountain lions and other wildlife in California for 20 years and directs the WHC’s California mountain lion study. He collaborates widely with other mountain lion researchers, as well as collaborating on studies involving bobcats, wolves, Channel Island foxes, Santa Cruz Island scrub jays, and waterfowl. He has also worked on oil spill response with the Oiled Wildlife Care Network at UC Davis.

The rolling hills of central Marin are covered with pastures, horse ranches, forested ridges, homes, reservoirs and occupied by many interesting birds. We will look for them in and around Nicasio and along the nearby stream before heading three miles north to see what is on and around Nicasio Reservoir. This is Bob’s birding “patch” and he has found both Bald and Golden Eagles recently with a nice array of other birds in this vicinity.
We expect to travel the few miles to Point Reyes Station for a lunch break or picnic. In the after- noon we will explore the south end Tomales Bay. Then, as time allows, we can explore the eastern edge of Tomales Bay along Highway 1, which supports a winter population of thousands of ducks, geese and shorebirds. We might travel 10 miles north to see if an Eagle’s nest is having success. Heavy Rain cancels.
DIRECTIONS: From Hwy 101 in north San Rafael take Lucas Valley Rd west 10.3 miles then right turn onto Nicasio Valley Rd for 0.5 miles and park near the baseball field, the center of town.

Birding with Josiah Clark
Register HERE for this Field Trip. Registration is required for this trip. Registration opens May 3rd at 8:00 AM.
The Presidio, part of the Golden Gate National Recreation Area since 1972, provides an excellent case study for the human and wildlife interface in San Francisco. Consulting Ecologist and San Francisco native, Josiah Clark, will share with us both the challenges and opportunities for wildlife and habitat preservation he has observed here. While the area has benefitted from the protection of the National Park Service and increased funding for special restoration projects, there have also been accompanying challenges brought about visitors, dogs, pathogens, and invasive plants that have all become more numerous as visitation to the area has dramatically increased.
We’ll meet Josiah at the Baker Beach Parking Lot, then travel on foot to Logos Valley, Mountain Lake Park, and the Presidio Hills before returning to Baker Beach. We’ll watch for signs of seasonal transitions in the area as wintering birds depart and the breeding season begins. A secondary focus for the trip will be habitat plants, some unique to the Franciscan scrub habitat, that Marin birders may not have seen. Heavy rain cancels.
DIRECTIONS: From Marin take Hwy 101 south to Merchant Rd. (Exit 439, first exit after the bridge) toward 25th Ave. in San Francisco. From Merchant Rd. turn right onto Lincoln Blvd. Next, turn right onto Bowley St. and right again onto Gibson Rd. Park in the Gibson Rd. parking lot. Parking is limited here, so ride with a friend if possible.

Islands and Avian Evolution

Speaker: Bob Lewis
Please register HERE for this Speaker Series
Islands have played a key role in both the development of new avian species and the extinction of others. Because they are isolated land masses, species which arrive on islands evolve separately from their parent group and through genetic drift eventually become unique. But because island species are restricted to small areas and have small populations, they are also susceptible to chance events, human-caused pressures, and predation by introduced species and introduced diseases.
In this presentation, we will focus on the wonders of these unique island species, as well as discuss some of the issues and threats to island avians.
Bob Lewis 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. Recently he’s been giving classes and talks via Zoom. Bob was honored with American Birding Association’s “Chandler Robbins Award” for Education and Conservation in 2016, and Golden Gate Audubon’s “Paul Covel Education Award” in 2010 and 2017. He loves to travel and photograph birds and has chased birds in over 40 countries. His life list is over 5000 species.

In 600 feet, turn left onto Bear Valley Rd. In approximately 0.5 mile, turn left at the entrance to Point Reyes National Seashore Headquarters at Bear Valley. We will meet at the picnic tables near the parking lot.

King Mountain Preserve - Larkspur
2023-06-09 08:00 - 10:30
Friday, June 9, 2023
8:00 AM to 10:30 AM
Birding with Rich Cimino and Janet Bodle
All participants are welcome to join this trip. No registration required.
Join us on King Mountain for a bird walk that welcomes beginners as well as experienced birders. This accessible Preserve, rising above the main streets in Larkspur, is frequented by hikers, but not so much by birders. Janet and I survey King Mt. as part the Marin Audubon Breeding Bird Atlas project. We would like to introduce Marin Audubon birders to this location.
It’s breeding season so any of the breeding migrants are probable, such as Lazuli Bunting, Black-throated Grey Warbler, and Yellow Warbler. Resident birds such as Wrentit and Pileated Woodpecker have been seen recently.
While the steep trail provides some excellent views, it can get quite warm. Bring liquid and wear a wide brimmed hat.
Directions from the corner of Magnolia Ave and Ward St in Larkspur: coming from north, turn right on Ward (left from the South), right on Hawthorne Ave, left on Willow Ave. Park and meet at trail head gate (Citron Fire Rd.) on Willow Ave.

For almost twenty-five years Marin Audubon Society (MAS) has been acquiring wetlands (or historical wetlands) and adjacent upland properties in Marin County; restoring, stewarding, and preserving the land as valuable wildlife habitat. Some of these properties came very close to being developed but ended up with MAS due to the perseverance of those individuals who early on understood the value and importance of wetland habitat. Some have been stewarded by an impressive group of dedicated volunteers and enjoyed for their beauty and bountiful birdlife by many people throughout the years.
Jude Stalker will take you on a virtual tour of several of these properties and fill you in on the interesting ways that they were acquired and of how they have been restored, enhanced, and stewarded to support the many native plants and animals that are populating them now.
Jude is a wetland biologist who has worked in and around the SF bay wetlands for over twenty years. She is a long-time member of the board of MAS and spends much of her free time volunteering to help steward the MAS (and other) properties.

Big Rock and Las Gallinas - Birding in Marin, Season 8, Trip 7
2023-07-01 08:30 - 15:00
Saturday, July 1, 2023
8:30 AM to 3 PM
Birding with Jim White and Bob Battagin
Register HERE for this Field Trip
Registration required for this trip. Registration opens on June 21 at 8:00 AM
Trails at Big Rock, rather steep, allow us to view some of the expansive grasslands and forested ravines in Marin. Some of the grassland nesting birds we will be looking for include Lazuli Bunting, Grasshopper Sparrow, Horned Lark, and Ash-throated Flycatcher. We will also have a vast amount of sky visible so swallows, swifts, and raptors may appear with a chance for a Golden Eagle.
At midday we expect to drive Lucas Valley Road to Las Gallinas where we will be looking for American and Least Bitterns, Green Heron, Cinnamon Teal, Common Gallinule, and Great-tailed Grackle.
DIRECTIONS: From Highway 101 in San Rafael, exit on Lucas Valley Rd and go west approximately 5.5 miles (look for the big rock). We will be walking approximately 3 miles. Because this area can get quite hot this time of year, be sure to wear a hat, use sunscreen and carry plenty of water.

Sky Trail and Limantour Beach - Birding in Marin
2023-08-05 08:30 - 15:00
Birding in Marin – Season 8, Trip 8
Birding with Jim White and Bob Battagin
Saturday 8/5/22
8:30AM – 3PM
Register HERE for this Field Trip
Registration required for this trip. Registration opens on July 27 at 8 AM on our TicketBud Site.

Meet at Sky Trailhead, near the crest of Limantour Rd. Directions below.

The Sky Trail, called “the misty spine of Bear Valley”, takes us through a maturing Douglas Fir/ Bishop Pine forest. Forest birds are more active early and moving birds often follow ridges so I would like to look and listen on our walk through this habitat. We may see or hear a Pileated Woodpecker, Band Tailed Pigeons, Steller’s Jays, Swainson’s Thrush, Osprey, nuthatches and surely Acorn Woodpeckers and Chestnut-backed Chickadees. Northern Spotted Owls, Western Screech and Saw-whet Owls live here but we would need to be here at dusk or dawn to hear them.
After we leave, we drive down to the great beach of Limantour with its miles of sand, its tidal estuary the open expanse of Drakes Bay and the Pacific Ocean beyond. We will gather at 9:30 in the ample parking lot with restrooms nearby. We’ll pack our lunches, shoulder our scopes and head out and up the beach. We can hike far enough to find Snowy Plovers to get our exercise and to cross over to the estuary side for our walk back. Gulls, terns, cormorants, loons, grebes, pelicans, murres, and guillemots will garner our attention and I’m always interested what the Pacific will bring close to shore. Shorebirds too, some already back from their breeding excursion to the Arctic, may decorate the shore or be gathering along the estuary shores and shallows. Some ducks, hawks, and herons will show up too.
Directions to Sky Trail: From CA 1 South, right (left from CA 1 North) onto Sir Francis Drake Blvd for 0.7 miles, left onto Bear Valley Road for 0.5, then right onto Limantour Road for 3.4 miles to the Sky Trailhead. Roadside parking is available near the trailhead. From Sky Trailhead, the drive to the Limantour beach parking lot is 4.3 miles.

Rodeo Lagoon - Marin Headlands

Wednesday, August 23, 2023 7:30/8:30 AM to noon **See notes below about start times.
Birding with William Legge and David Wiechers
Register HERE for this Field Trip
Registration required for this trip. 15 Participants max. Registration opens on August 13 at 8 AM.
Join William and David for the first of four fall migration field trips at Rodeo Lagoon. This is their long-time “patch,” which never seems to disappoint birders with daily variations in species and the chance of an unusual sighting. On this trip, our group will be targeting Elegant Terns and Parasitic Jaegers, migrating shorebirds, and western passerine migrants including warblers. We will begin the morning with a Sea Watch at 7:30 AM from Rodeo Beach. Those arriving later may join us 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 light. Proceed through the tunnel on Bunker Rd to the Rodeo Lagoon Parking Lot at the end. Meet by the bridge over the channel to the beach or join MAS birders with scopes along the nearby beach area.

Abbott’s Lagoon – Pt. Reyes National Seashore
2023-08-26 09:00 - 14:00
Saturday, August 26, 2023
9:00 AM – 2:00 PM
Leader: Rusty Scalf
All participants are welcome to join this trip. No registration required.
We will bird the coastal scrub, lagoons, and ocean. We hope to find migrant shorebirds and resident Snowy Plovers. Abbott’s Lagoon has historically been good for Baird’s Sandpiper and we may get lucky. Meet at 9am at the Abbotts Lagoon parking lot (bathrooms but no water). Bring scope, liquids, lunch. Plan on walking 4 miles round-trip; relatively flat but trail consists partially of sand. Prepare for wind.
DIRECTIONS: From Point Reyes Station on Hwy 1 go just south of town, right turn onto Sir Francis Drake Blvd, follow that thru Inverness up over Inverness ridge into the Point Reyes National Seashore then go north on Pierce Point Road. The Abbott’s Lagoon parking lot is on the left in about 3 miles. Carpool if you can.

8:30 AM to mid-afternoon

Register HERE for this Field Trip
Registration is required for this trip. Registration opens August 23 at 8AM.
This is the place to be for fall birding. Many migrants like hawks, jaegers, shorebirds and loons follow the coast south. Many songbirds, migrate at night and seem to have a compass bearing in mind, momma said to fly “15 degrees east of due south for 4 days.” Millions of recently fledged birds undertake a journey of 2-4000 miles without a google assistant and many without further parental guidance. Some get lost.
Imagine that you are a dyslexic Connecticut Warbler hatched in early June in the boreal forest of north central Canada. It is your second night flight, you are flying west instead of east or south, you crossed some mountains so that you are flying sort of high, morning is approaching so you descend thru the clouds and there is nothing but water. A fog shrouded coast was not in your flight plan. You reverse directions, trying to avoid the gulls and jaegers pursuing you, when you see trees miles away on a point sticking above the fog. Relief, a place to land, to rest, and to find something to eat. These vagrant warblers and other eastern songbirds are the reasons that the tree islands of the Point Reyes peninsula are so popular with birders
We intend to visit the nearby Fish Docks after The Light house then work our way back to Drake’s Beach for lunch and much more birding.
Directions: Meet at 8:30 at the Lighthouse parking area. The Lighthouse parking area is at the west end of S F Drake. Going north thru Inverness follow Drake to the Lighthouse. Allow 30 min from Inverness or 1.5 hour from San Rafael.

The Ponds at Las Gallinas Valley Sanitary District (LGVSD)
2023-09-07 08:30 - 12:00
Thursday, September 7, 2023
8:30 AM to noon
Birding with Sande and Bob Chilvers
No registration required. All participants are welcome to join this trip.
Join old friends and meet new ones as we resume our regularly scheduled walks on the first Thursday of the month at Las Gallinas. We especially welcome beginning birders on this leisurely walk around the ponds. 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. Among other birds, we will see various species of rails, swallows and teals. 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. 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.
