Marin's Declining Shorebirds
2024-06-13 19:00 - 21:00 (America/Los_Angeles)
Thursday, June 13, 2024
7:00pm – 9:00pm
Speaker: Nils Warnock
Register HERE for this Speaker Series
Topic: Nils will talk about the status and trends of our North America shorebirds, with a focus on Pacific Flyway birds, particularly those that occur in Marin County. He will first discuss how shorebirds around the world and in the USA are doing and then talk about the results of a 30+ year winter shorebird monitoring program that Audubon Canyon Ranch has been conducting at Tomales Bay since 1989. Overall, numbers of wintering shorebirds on Tomales Bay have declined by over 65% over the past decades with Dunlin and Western Sandpipers among the biggest losers. Of the 14 taxa that ACR analyzed, 3 increased over the past 30 years, 1 stayed stable, and 11 species declined. Nils will discuss potential reasons why our shorebird populations have declined and what we might do about it.
Speaker Bio: Nils Warnock has been the Director of Conservation Science for Audubon Canyon Ranch since 2018 and lives on Tomales Bay in Marshall, CA. He has a PhD in Ecology from the University of California at Davis and San Diego State University. Nils started his ornithological career in West Marin at the Point Reyes Bird Observatory (now Point Blue), where, most recently, he was the co-director of the Wetlands Division from 2000-2008. From 2010-2018, Nils served as the executive director of Audubon Alaska and as a vice president of the National Audubon Society. Nils is a Fellow of the American Ornithological Society and has 40 years of experience working with Pacific Flyway birds, especially shorebirds.

8:30 am – 2:00 pm
Birding with Liz Lewis and Susan Kelly
Register HERE for this Field Trip
Registration required. Registration opens June 2 at 8 AM
Would you like to contribute to the second Marin County Breeding Bird Atlas? Join MCBBA2’s Liz Lewis and Susan Kelly for a morning of blockbusting birding in Outer Point Reyes including the cypress tree tunnel to the historic RCA radio station. Time permitting, we will explore the abandoned ranch as well. Block 3-4 is a high priority block with minimal data collected to date. Species we might see or hear include: Allen’s Hummingbird, Swainson’s Thrush, Northern Harrier, and Western Meadowlark.
The Atlas II is a four-year project that builds on the first Atlas begun in the 1970s by Bob Stewart and Dave Shuford that occurred over four field seasons, where they supervised scores of volunteers in data collection using a grid system overlaid onto topographic maps of Marin County to determine the current distribution and composition of breeding birds. Their fieldwork culminated in the publication of Shuford’s landmark Marin County Breeding Bird Atlas. Now four decades later, 70 volunteers are in their fourth year of collecting data to determine where we are now. All the data is being stored digitally with the California Avian Data Center (CADC) and can be accessed by the public through the MCBBA2 Data Explorer.
Directions from the Point Reyes National Seashore Visitor Center:

From the Bear Valley Visitor Center, head north 0.2 miles (0.3 km) to Bear Valley Road.
Turn left and follow Bear Valley Road 1.75 miles (2.8 km) northwest to Sir Francis Drake Boulevard.
Turn left and follow Sir Francis Drake Boulevard 9.5 miles (15.2 km) north and west.
Follow road signs for “Lighthouse” until you see a sign for “North District Operation Center.”
Parallel park on the shoulder along Sir Francis Drake Boulevard near the entrance to the cypress tunnel.

Parking is limited to the shoulder of Sir Francis Drake Boulevard at the entrance to the cypress tree tunnel so carpooling is encouraged. Restrooms are available at the Visitor’s center and at the North Beach parking lot.

Re-discovering and Conserving the Black-Naped Pheasant-Pigeon, A Critically Endangered Species
2024-03-14 19:00 - 21:00
Thursday, March 14, 2024
7:00 PM – 9:00 PM
Speaker: Jordan Boersma, Cornell Lab of Ornithology
Register HERE for this speaker series
Topic:
Jordan will discuss the Black-naped Pheasant-Pigeon, a critically endangered species that hasn’t been documented by scientists since it was first described in 1882. In 2022, Jordan and his team embarked on an expedition to Fergusson Island, Papua New Guinea, and by leveraging the natural history knowledge of local hunters, was able to confirm the existence of this species, known locally as Auwo., thus demonstrating the invaluable role of Indigenous communities in ongoing efforts to relocate species lost to Western science. Plans are to build on the partnerships formed in 2022 to help conserve this elusive and culturally important species and continue to uncover natural history information about Auwo and other endemic taxa on Fergusson island.
Speaker Bio:
Dr. Jordan Boersma’s interest in animals led to pursuing a degree in Wildlife Biology from the University of Montana. While there, he got involved in a local study on nesting songbirds, which led to an opportunity in the same research group in Malaysian Borneo, where he spent four long field seasons before pursuing a Ph. D at Washington State University. During his extensive field seasons in New Guinea, he learned that Indigenous people harbored immense knowledge of local fauna and is now working with local communities to study and conserve rare and potentially imperiled species.

Birding with Jim White and Bob Battagin
Register HERE for this field trip
Registration opens Wednesday, February 21st at 8 AM.
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.

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. Bring rain gear as needed!
Ticket holders will receive instructions and directions to the Antioch Marina, where the trip begins and ends, approximately one week prior to the trip.

Topic:
There is a small but locally significant breeding population of western snowy plovers at Point Reyes National Seashore. They are federally listed as Threatened and California state listed as a Species of Special Concern, but the local breeding population size has been gradually increasing over the past half decade due to intensive management and monitoring across the range. Matt will present on the fascinating breeding biology of western snowy plovers, cover local conservation issues that snowy plovers face, and review local population trends and ongoing research and management at Point Reyes National Seashore.
Speaker Bio:
Matt is a wildlife biologist with Point Reyes National Seashore and leads the management and monitoring program for western snowy plovers. He has worked with snowy plovers for over a decade, at Point Reyes National Seashore and in northern California while working on his master’s degree at Cal Poly Humboldt. As a National Park Service biologist, he also conducts surveys of breeding northern elephant seals, Point Reyes Mountain beavers, and tule elk. His interests include shorebird ecology, bat conservation, spatial ecology, conservation education, and diversity and inclusion work.

Registration opens Wednesday, January 24 at 8 AM.
We are going to explore the bay from the Sausalito water front 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 find close comparative looks at similar species pairs 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. 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.

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.

Daniel invites you to discover the joy of a wilderness-like paradise — Skaggs Island Road — that often attracts dozens of shorebird and duck family members, in addition to uncommon, visiting non-breeding raptors such as Rough-legged Hawk, Ferruginous Hawk, and Merlin (along with sightings of White-tailed Kite and other raptor species).
Closed to the public, Skaggs Island Road is accessed by meeting our group in the parking area adjacent to Hwy. 37 (approximately 3 miles east of Reclamation Road and 2 miles east of the Highway 121/Sears Point Raceway intersection (at the stoplight). We’ll meet on the north side of Hwy. 37 where it intersects with Skaggs Is. Rd. and bird together while walking north on the road.
Please be careful turning into this road when coming from Marin Co. because oncoming traffic is often heavy.

SPECIAL INTRODUCTION TO BIRDING – WINTERING WATERBIRDS
Wednesday, January 17, 2024
10:00 AM to 12:00 PM
Register HERE for this Field TripRegistration required. Registration opens on January 7 at 8:00 AM.
Join Roger Harris and other Marin Audubon board members for a field trip specifically designed for people interested in getting some of the birding basics down. And there is no place better suited for that than the half-mile-long flat and paved levee path at the Loch Lomond Marina. With panoramic views of the surrounding bay, we should get close-up views of wintering waterbirds including Black Turnstones, diminutive Least Sandpipers, Black Oystercatchers with bubblegum pink legs, Snowy Egrets sporting golden slippers, and a variety of ducks, grebes, gulls, and cormorants. This is a terrific place for photography, if you like, but each participant is requested to bring binoculars.
DIRECTIONS: Head east on Second Street in San Rafael, which turns into Point San Pedro Road. Continue approximately 2 miles past the Montecito Shopping Center to a red light at the intersection of Point San Pedro Road and Loch Lomond Drive. Turn right here, then turn left in front of Andy’s Market (75 Loch Lomond Dr.) where the road comes to a “T” at the waterfront. Continue all the way east to the end of the road where you will find ample parking and a public restroom.
Dress warmly as some winter days here are cold and windy. Heavy rain cancels.

Northern Spotted Owls
2024-01-11 19:00 - 21:00
Thursday, January 11, 2024
7:00pm – 9:00pm
Speaker: Taylor Ellis, U.S. National Park Service
Register HERE for this Speaker Series
Topic:
Taylor will discuss Marin’s unique spotted owl population, which is geographically and genetically distinct from other northern spotted owl populations to our north. Northern spotted owls are considered an indicator species of healthy forests and were federally listed as a threatened subspecies in the 1990s and have been monitored closely by the National Park Service and Point Blue since then. Taylor will discuss the main threats to Marin’s spotted owls, including the threat from barrel owls, who have taken over most of the nesting sites for spotted owls to our north. He will also discuss what makes Marin’s spotted owl population so unique relative to others.
Speaker Bio:
Taylor Ellis is a wildlife technician at Point Reyes National Seashore, where he implements the northern spotted owl monitoring program as well as monitoring other wildlife species throughout the year. Taylor has been working with spotted owls for 20 breeding seasons since first interning with the U.S. Forest Service in New Mexico in 2003. Taylor received his M.S. in Biology from Sonoma State University after studying the indirect impacts of tule elk on small mammal populations at Tomales Point in Point Reyes National Seashore.

Register HERE for this Field Trip
Registration opens on December 27, 2023 at 8 AM
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
No registration required. All participants are welcome to join this trip.
Join old friends and meet new ones on our regularly scheduled walks on the first Thursday of the month at Las Gallinas. We welcome bird enthusiasts of all levels, especially 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 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.
