Birding with Bryan Flaig
Register HERE for this field trip

Registration opens on Thursday, November 24 at 8 AM. Trip limit is 20 participants. No drop ins, please. 

This trip is perfect for beginning birders looking to learn how to identify waterfowl and shorebirds, as well as experienced birders interested in honing their skills. Corte Madera Ecological Reserve contains a variety of birding habitats, like tidal ponds, pickleweed marshes and a high tide refuge purchased by Marin Audubon in 2016. Much of the area has undergone extensive restoration for rare and endangered salt marsh species.

On this field trip, we will hike a short distance to explore the marsh at high tide, searching for elusive Ridgway’s Rails and winter residents. We’ll walk along the east side of Shorebird Marsh (pond), observing the wide variety of ducks, gulls, and wading shorebirds that frequent the area this time of year.

Restrooms are available at nearby stores (Trader Joe’s), but not on the marsh. Bring binoculars, scopes, layers, water, and snacks. Plan for a 1.5 to 2 mile walk on flat terrain. Light rain does not cancel the trip.

DIRECTIONS: Corte Madera Ecological Reserve is located behind Trader Joe’s in Corte Madera. Meet in the parking lot behind the store, accessed by the driveway on the south side of World Market.

Birding with Sande and Bob Chilvers 

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

Join old friends and meet new ones on our regularly scheduled walks on the first Thursday of the month at Las Gallinas. With fall migration just about over, we might see more waterfowl and spot 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. 

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.

Registration opens on December 28, 2022 at 8 AM. Trip limit is 15 participants. No drop-ins, please.

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

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.

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.

This very popular trip is being held the first weekend in Feb on Sunday Feb 5. We’ll depart from the Antioch Marina at 9AM and enter the San Joaquin River, keeping an eye out for overwintering birds and any marine (or other) animals that happen to show up. As we head east, we enter a number of the smaller sloughs and waterways with views out over the flooded agricultural fields that provide a refuge for flocks that nest in the north but winter here.

Along with the flocks of snow geese, white fronted geese and Tundra swans, numerous ducks, shorebirds, and raptors are usually spotted. Well known birder and naturalist David Wimpfheimer will provide commentary and Ronn Patterson (captain and naturalist) will fill in bits about the history of the delta as we transit this altered but still viable ecosystem.

Coffee, tea, hot chocolate is provided, bring lunch and snacks. Bad weather can cancel as with any winter trip. Light rain will not cancel.

Ticket holders will receive directions to the Antioch Marina, where the trip begins and ends, and other instructions, approximately one week prior to the trip. 

Inclement weather will reschedule the trip to Sunday, February 19.

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.

Registration for this trip is required. Registration opens Wednesday, March 22 at 8 AM. 

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 3^rd 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.

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.
