Birding in Marin – Bahia (Horseshoe Pond & Rush Creek)

DECEMBER 4 @ 8:30 AM - 2:00 PM

Saturday 12/04/21 from 8:30 to 2 PM – CLICK HERE to register for this field trip

Birding with Jim White and Bob Battagin

Registration for this trip will be open starting on November 24 at 8:00 AM. There is a limit of 15 for this trip. There will not be a waiting list, and no drop-ins allowed. All participants must be fully vaccinated.

The Marin Audubon Society acquired and restored to tidal action the diked baylands around the residential Bahia neighborhood. As the ebbing tide exposes the mudflats thousands of shorebirds now descend to feed while on the flood tide hundreds of ducks and some gulls float, forage and loaf about. The oak wooded ridge stretching from 101 to Bahia, also saved from development by MAS, holds Oak Titmice, White-breasted nuthatch, Hutton’s Vireo at least 4 woodpecker specie and many sparrows in the winter. It is always interesting and we have had Golden Eagles soaring above.

The horseshoe pond at the south east 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 take a look at the nearby Rush Creek area from the Airport Road which parallels the 101 freeway north of Atherton. So join Bob and Jim if you would like enjoy a day of birding and see about 80 species on the day.

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.

Birding at the Cosumnes River Preserve

DECEMBER 11 @ 1:00 PM - 5:00 PM

Saturday, December 11 2018 – 1 PM to 5:30 PM – CLICK HERE to register for this field trip

Birding with Kurt Rademacher

Registration for this trip will be open starting on December 1 at 8:00 AM. There is a limit of 15 for this trip. There will not be a waiting list, and no drop-ins allowed. All participants must be fully vaccinated.

At the junction of the Great Central Valley and Delta, the Cosumnes River Preserve is a 46,000-acre conservation project acquired and jointly managed through the collaboration of a number of conservation organizations and agencies. Here, the last un-dammed river on the west slope of the Sierra still routinely floods up in winter, fostering bountiful habitats of wetlands, savannah and riparian forest for wintering waterfowl, shorebirds, songbirds and raptors. Tundra Swans, Shovelers, American Wigeon, Green-winged & Cinnamon Teal, Pintails, White-faced Ibis, and White Pelicans are among the winter throngs. Greater and Lesser Sandhill Cranes are a highlight of our tour, and we’ll end up at Staten Island for sundown to witness the spectacle of some 15% of the Pacific Flyway’s cranes noisily settling down for their nightly roost.

DIRECTIONS: We’ll meet at the Cosumnes River Preserve Visitor Center parking lot at 13501 Franklin Blvd, Galt. Allow about two hours from Central Marin via Hwys 37, 80 and 12 through Rio Vista to I-5, then north to Twin Cities Rd. exit. (Or you can take I-80 to Sacramento, then south on I-5 to Twin Cities Rd. exit.) On Twin Cities Rd. proceed east briefly to turn right (S) on Franklin Rd. about 1.7 miles to the parking area. You are wel- come to come earlier and enjoy your lunch on the Visitor Center veranda. After a briefing at 1 PM, we’ll enjoy a 1-mile loop hike on a trail and boardwalk, then drive to other key observation points on the preserve ending up at Staten Island. Come prepared with warm clothing for changeable weather including rain and mud for “Crane-down.”

Birding in Marin – Stinson Beach & Bolinas

JANUARY 8, 2022 @ 8:30 AM - 2:00 PM

January 8th, 2022 – 8:30 AM – 2:00 PM – CLICK HERE to register for this field trip

Birding with Jim White and Bob Battagin

Registration for this trip will be open starting on December 29 at 8:00 AM. There is a limit of 15 for this trip. There will not be a waiting list. No drop-ins allowed. All participants must be fully vaccinated.

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, Christmas Bird Counts, show this to be most specie rich, birdiest, area in Southern Marin county. These habitats include 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 shores. Can we find 100 specie today?

Thanks can 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 around Bolinas Lagoon. Dr Martin Griffith was instrumental in saving Bolinas harbor from a hotel and yacht club destination and 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 and will help by providing a list of the birds that we encounter today. We strive to help all of our participants to see or hear all of the birds but that is a goal, not quite reality. Let’s go birding!

DIRECTIONS: Meet at 8:30 AM at the Stinson Beach Parking Lot
