Birding with Jim White and Bob Battagin
Register HERE for this field trip

Registration opens on November 24 at 8 AM. Trip limit is 15 participants. No drop-ins, please. 

MAS acquired and restored to tidal action the diked bay lands around the residential Bahia neighborhood. As the ebbing tide exposes the mudflats to thousands of shorebirds, while on the flood tide hundreds of ducks and some gulls float, forage and loaf about. The oak-wooded ridge stretching from Hwy 101 to Bahia, also saved from development by MAS, holds Oak Titmice, White-breasted Nuthatch, Hutton’s Vireo, at least four woodpecker species and many sparrows in the winter.

Homeowners Lagoon at the southeast end of Topaz is a great place to look for wintering ducks. Goldeneyes, Scaup, Canvasbacks, Buffleheads, and Mergansers seem to like it and it has been Marin’s best place for Barrow’s Goldeneyes the last few years.

After lunch we plan to look at the nearby Rush Creek area from the Airport Rd which parallels Hwy 101 north of Atherton.

DIRECTIONS: From 101 in north Novato take Atherton Avenue east, take the Y left onto Bugeia which becomes Bahia Drive, near the end at the bottom of the hill take a right onto Topaz, follow Topaz to its end and park.

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

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

CA, United States

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.

Birding in Marin – Sausalito and Tiburon

CA, United States

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.

Winter Birds of the Delta – Boat Trip

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.

Birding in Marin – Mt Tam and Corte Madera Marshes

CA, United States

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.

The Presidio – San Francisco

CA, United States

Saturday, May 13th
8 AM to 12 PM
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.
