Southern Marin Christmas Bird Count Historical Data by Species and Area Maps

This page is a wonderful resource if you’re interested in the data we’ve obtained from our Count over the years, or would like to download a map of the area where you will be counting. It includes data sheets for the entire Count, and for each individual area. Each data sheet provides the complete numbers, by species, of all birds that were counted on each year’s CBC, from 1978 through 2009. Participants can use these sheets to determine which species they might expect to see in a particular area. Also, there are maps for the each area, and one with an overview of the complete Count circle. All the files are in PDF format, and you can save them on your computer for further analysis.

Field Trips

Dec 10

Corte Madera Ecological Reserve – December #2

DECEMBER 10 @ 9:00 AM - 12:00 PM

Saturday, December 10, 2022
9:00 AM to noon
Birding with Bryan Flaig
Register HERE for this field trip

Registration opens on Thursday, November 30 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. 

Become a chapter supporting member of the Marin Audubon Society starting at $35 a year, or RENEW your membership today! Your membership helps to fund important efforts such as our ongoing habitat restoration projects, the Monarch Rescue Project, and our Northern Spotted Owl Outreach program. We cannot do these important projects, along with our many other efforts, without the support of our dedicated members!

The Ponds at Las Gallinas Sanitary District (LGVSD)

JANUARY 5, 2023 @ 8:30 AM - 11:30 AM

Thursday, January 5, 2022
8:30 to 11:30 AM
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.

STINSON / BOLINAS

JANUARY 7, 2023 @ 8:30 AM - 3:00 PM

Birding in Marin Season 8-Trip 1
Saturday, January 7, 2023
8:30 AM to mid afternoon
Birding with Jim White and Bob Battagin
Register HERE for this field trip

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

Winter Birds of the Delta – Boat Trip

FEBRUARY 5, 2023 @ 9:00 AM - 3:00 PM

Birding with David Wimpfheimer
Sunday, February 5th, 2023
Boat departs at 9 AM. Plan to arrive early!
Register HERE for this field trip. Please see below for important registration information.

The trip costs $135. Limited to 25 people. Registration for this trip opens January 9 at 8AM. Tickets may be cancelled until February 2 at 12 noonCancellations will be refunded MINUS the TicketBud service charges.

If tickets aren’t available, you may sign up for the waitlist by clicking the “Contact Organizer” prompt on Ticketbud and leaving your name and phone number. 

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.
