Las Gallinas and Hamilton Wetlands - Birding in Marin - Season 7, Trip 11
2022-11-05 08:30 - 15:30 (America/Los_Angeles) | CA, United States
Saturday, November 5, 2022
8:30 AM to mid afternoon (3PM)
Birding with Jim White and Bob Battagin
Register HERE for this Field Trip
Registration will be open starting on October 27 at 8 AM. There is a limit of 15 participants for this trip. There will not be a waiting list. No drop-ins, please.
Join Jim and Bob on an easy, birdy walk of 1.5 miles around the Las Gallinas ponds where we are likely to see 10 species of ducks, five of herons, five of raptors, five of sparrows and some rails like Ridgway’s, Sora, and Virginia with Gallinules, coots, swans and geese! Shall we try to identify the duck species by females? I wonder if the Merlin will be back. These oxidation ponds, where a large portion of Marin’s waste water is converted to useful nutrients and clean enough to return safely to the San Francisco Bay ecosystem, demonstrate how we can provide for wildlife and live in harmony with nature.
After lunch we are going to visit the Hamilton Wetlands, restored by the Army Corp. of Engineers in the recent 5–10 years to the SF Bay ecosystem, which have become the winter home of some ten thousand birds. It is remarkable that thru the 2nd World War and the Cold War years the US
Air Force stayed on alert and could launch jet fighter planes in minutes from an airport here to defend the Bay Area. We will try to find 10 species of shorebirds here while staying alert to many other possibilities.
DIRECTIONS: From 101 north San Rafael take the Lucas Valley/Smith Ranch Road exit east. In about 0.5 miles, immediately after crossing the RR tracks, left turn and follow the road another 0.5 mile to the Las Gallinas parking at the end.
To the Hamilton Wetlands return to 101 North, take the second exit, Nave Drive toward Hamilton. Stay on Nave Dr, heading north, to Main Gate Dr and turn right. Go east to Hanger Ave and park along the levee behind Hangar 7.

The story of hummingbird evolution starts about 50 million years ago, far from the lands they currently inhabit. We’ll trace the history of their evolution and then briefly discuss relationships between the 9 tribes of living species. After reviewing California’s 7 most common species – all belonging to the Bee tribe, we’ll look at other North American species, and then examine representatives of the other tribes, mostly concentrated in South America. Finally, we’ll consider some conservation issues and end with a few words on hummingbird photography.
Bob trained as a chemist and worked in the energy field for 33 years. He’s taught birding classes in the Bay Area for over 25 years and served as the chair of Golden Gate Audubon’s Adult Education Committee. Bob was honored with American Birding Association’s Chandler Robbins Award for Education and Conservation in 2016. He loves to travel and has photographed and chased birds in over 40 countries. His life list is over 5000 species.

Limit of 15 fully vaccinated participants for this trip. Registration opens on our TicketBud sight on September 25 at 8AM.
With large numbers of birds moving through the area this time of year, it’s sure to be an interesting outing with unusual sightings a definite possibility. We’ll start with a 30-40 minute visible migration and sea watch from Rodeo Beach hoping for Parasitic Jaegers as well as other passing goodies before undertaking an extended circuit of Rodeo Lagoon in the search for scarce migrants including early winter wildfowl, shorebirds and fall passerines. More than 60 species should be possible at this time of year. The morning will begin with a sea watch at 7:30 AM.
DIRECTIONS: Head south on Hwy 101 and take the last Sausalito exit just before the Golden Gate Bridge. At the exit stop sign, turn right and go under the freeway, then follow the road down to the left. Within 300 feet turn left at the sign to the Marin Headlands (This is the only available left turn before you begin the descent into Sausalito). You should see the tunnel with the five-minute light. Proceed through the tunnel on Bunker Road to the Rodeo Lagoon Parking Lot at the end and meet by the bridge over the channel to the beach.

This is the place to be for fall birding. Many migrants like hawks, jaegers, shorebirds and loons follow the coast south. Many songbirds, migrate at night and seem to have a compass bearing in mind, momma said to fly “15 degrees east of due south for 4 days.” Millions of recently fledged birds undertake a journey of 2-4000 miles without a google assistant and many without further parental guidance. Some get lost.
Imagine that you are a dyslexic Connecticut Warbler hatched in early June in the boreal forest of north central Canada. It is your second night flight, you are flying west instead of east or south, you crossed some mountains so that you are flying sort of high, morning is approaching so you descend thru the clouds and there is nothing but water. A fog shrouded coast was not in your flight plan. You reverse directions, trying to avoid the gulls and jaegers pursuing you, when you see trees miles away on a point sticking above the fog. Relief, a place to land, to rest, and to find something to eat. These vagrant warblers and other eastern songbirds are the reasons that the tree islands of the Point Reyes peninsula are so popular with birders
We intend to visit the nearby Fish Docks after The Light house then work our way back to Drake’s Beach for lunch and much more birding.
Directions: Meet at 8:30 at the Lighthouse parking area. The Lighthouse parking area is at the west end of S F Drake. Going north thru Inverness follow Drake to the Lighthouse. Allow 30 min from Inverness or 1.5 hour from San Rafael.

Vaux Swifts at McNear Brick and Block

Limit of 15 fully vaccinated participants for this trip. Registration opens September 7 at 8AM
Join other MAS members for an evening opportunity to witness Vaux’s Swifts during their fall migration through Marin, which occurs in September and October. Dan McNear of McNear Brick & Block has kindly allowed Marin Audubon to access this remarkable site where three decommissioned chimneys provide an important communal evening roosting place for the Vaux’s swifts.
Watching tens of thousands of Vaux’s swifts as they descend into the stacks just before night- fall is an unforgettable sight. At the peak of migration, as many as 19,000 swifts have been counted in one evening. However, keep in mind that the number of swifts varies greatly from night to night and can range from a few hundred to thousands. Like everything else in birding, there are no guarantees!
Sunset on the evening of our visit will be at 7:11 PM, so plan on arriving on time to be ready. If the weather on the day of our trip is particularly cool or windy, the swifts are likely to enter the stacks early, so plan accordingly. Bring scopes, binoculars, and, if desired, folding chairs for your seating comfort. It can be chilly at dusk. Please stay with our group and do not enter any of the private areas on the property. Use soft voices and be sure to respect the privacy of local residents.
DIRECTIONS: From Hwy 101 take the Central San Rafael exit. Head east on Third St./Point San Pedro Rd for about 3.5 miles. The brickyard will be on the right. The address is 1 McNear Brickyard Rd. Park as close to the San Pedro Road entrance as possible. Please do not drive to or park near the closed gate.

Join William and David for this fall migration field trip at Rodeo Lagoon. This is their longtime “patch,” which never seems to disappoint birders with daily variations in species seen and unusual sightings. On this particular trip, our group will be targeting Parasitic Jaeger, migrating shorebirds, warblers, and other passerines. We will begin the morning with a Sea Watch at 7:30 AM. Those arriving later may join us at 8:30 AM for a circuit of the lagoon.
DIRECTIONS: Head south on Hwy 101 and take the last Sausalito exit just before the Golden Gate Bridge. At the exit stop sign, turn right and go under the freeway, then follow the road down to the left. Within 300 feet turn left at the sign to the Marin Headlands (This is the only available left turn before you begin the descent into Sausalito). You should see the tunnel with the five-minute light. Proceed through the tunnel on Bunker Rd to the Rodeo Lagoon Parking Lot at the end. Meet by the bridge over the channel to the beach or join MAS birders with scopes along the nearby beach area.

Abbott’s Lagoon on the Pacific Coast in the Point Reyes National Seashore is one of Marin’s premier birding locations sporting an eBird sum of 283 species. Fall migration south along the coast brings many birds to this area. Some that we hope to see include Ferruginous Hawk, Baird’s and Pectoral Sandpipers, Red-necked Phalaropes, Lapland Longspur, Horned Lark and Pipits. Hundreds of ducks of a dozen species, geese, herons, Peregrines and Ospreys are also likely visitors. Plus you get some exercise; out and back is about 3 miles (some in sand) and Jim likes to do a full 5-mile loop. So pack a lunch for a picnic on the beach and bring a couple of layers for the fresh ocean air and help us spot a rarity.
To help bolster our participant’s species lists to our yearly goal of 200, we plan to stop along Tomales Bay near the Inverness Tennis club to look for Pine and Alder woodland birds. A surprising number of species have been seen here and there is a nice little beach where we usually find several kinds of gulls.
DIRECTIONS: From Point Reyes Station on Highway 1 go just south of town, right turn onto Sir Francis Drake Blvd, follow that thru Inverness up over Inverness ridge into the Point Reyes National Seashore then go north on Pierce Point Road. The ABBOTT’s Lagoon parking lot is on the left in about 3 miles. Car Pool if you can, allow 1.5 hours from San Rafael and please be vaccinated.

Meet; at Sky Trailhead at 8:30 AM, near the crest of Limantour Rd. Directions below.
Register for this field trip HERE
Limit of 15 fully vaccinated participants for this trip. Registration opens on July 27.
The Sky Trail, called “the misty spine of Bear Valley”, takes us through a maturing Douglas Fir/ Bishop Pine forest. Forest birds are more active early and moving birds often follow ridges so I would like to look and listen on our walk through this habitat. We may see or hear a Pileated Woodpecker, Band Tailed Pigeons, Stellar’s Jays, Swainson’s Thrush, Osprey, nuthatches and surely Acorn Woodpeckers and Chestnut-backed Chickadees. Northern Spotted Owls, Western Screech and Saw-whet Owls live here but we would need to be here at dusk or dawn to hear them.
After we leave, we drive down to the great beach of Limantour with its miles of sand, its tidal estuary the open expanse of Drakes Bay and the Pacific ocean beyond. We will gather at 9:30 in the ample parking lot with restrooms nearby. We’ll pack our lunches, shoulder our scopes and head out and up the beach. We can hike far enough to find Snowy Plovers to get our exercise and to cross over to the estuary side for our walk back. Gulls, terns, cormorants, loons, grebes, pelicans, murres, and guillemots will garner our attention and I’m always interested what the Pacific will bring close to shore. Shorebirds too, some already back from their breeding excursion to the Arctic, may decorate the shore or be gathering along the estuary shores and shallows. Some ducks, hawks, and herons will show up too.
Directions to Sky Trail: From CA 1 South, right (left from CA 1 North) onto Sir Francis Drake Blvd for 0.7 miles, left onto Bear Valley Road for 0.5, then right onto Limantour Road for 3.4 miles to the Sky Trailhead. Roadside parking is available near the trailhead.
From Sky Trailhead, the drive to the Limantour beach parking lot is 4.3 miles.

Trails at Big Rock, rather steep, allow us to view some of the expansive grasslands and forested ravines in Marin. Some of the grassland nesting birds we will be looking for include Lazuli Bunting, Grasshopper Sparrow, Horned Lark, and Ash-throated Flycatcher. We will also have a vast amount of sky visible so swallows, swifts, and raptors may appear with a chance for a Golden Eagle.
At midday we expect to drive Lucas Valley Road to Las Gallinas where we will be looking for American and Least Bitterns, Green Heron, Cinnamon Teal, Common Gallinule, and Great-tailed Grackle.
Fully vaccinated participants can register for the Big Rock/Las Gallinas trip starting on June 22 at 8:00 AM on the MAS website Field Trips page.
DIRECTIONS: From Highway 101 in San Rafael, exit on Lucas Valley Rd and go west approximately 5.5 miles (look for the big rock). We will be walking approximately 3 miles. Because this area can get quite hot this time of year, be sure to wear a hat, use sunscreen and carry plenty of water.

Thursday, June 9 at 7:00 PM
Speaker: Dan Airola
Register for the June Speaker Series Zoom program HERE
The Tricolored Blackbird has declined dramatically from its historical abundance to become a state-listed species, as a result of massive land-use changes in California’s Central Valley. The species has adapted and now occupies a variety of novel habitats, including agricultural fields and grazing lands in the Sierra Nevada foothills. Dan Airola has studied Tricolored Blackbirds over the last decade in the valley and foothills to understand their population status, habitat requirements, future land use threats, and conservation management. He offers a conservation assessment addressing both the challenges of land use change and encouraging efforts to conserve the species.
Raised in Marin County, wildlife biologist and ornithologist Daniel Airola conducts research and conservation efforts for birds of concern in northern California. He is a member of the statewide Tricolored Blackbird Working Group and leads its Research Committee. Other research species include the Purple Martin, Yellow-billed Magpie, Swainson’s Hawk, and Osprey. His recent book on 30 years of Purple Martin research and management is available at cvbirds.org.

Speaker: Renee Cormier
Register for this Speaker Series HERE
Please join us for a presentation by Point Blue Conservation Science’s, Renée Cormier, to learn about Northern Spotted Owl natural history, conservation of this iconic species, and the long-term monitoring of this species in Marin County. Northern Spotted Owls are federally “Threatened” and state “Threatened” in California, but Marin County – at the southernmost extent of their range – is a stronghold for this subspecies. Renée is an avian ecologist at Point Blue, where she started as an intern in 2002. In addition to her work on long-term landbird studies at the Palomarin Field Station, and migration studies of songbirds, and she has been working with Spotted Owls in Marin County since 2006.

Illustration by Keith Hansen
Our program focuses on highlights from Hansen’s Field Guide to the Birds of the Sierra Nevada, artist-naturalist Keith Hansen’s sixteen-year project to illustrate the birds of the Sierra Nevada. From the tiniest hummingbirds to condors with nine-foot wingspans, Keith brings his artist’s perspective to the identification and characteristics of his avian subjects through his beautiful illustrations and unique descriptions.
Keith’s path to his life’s work began as a barefoot kid exploring the woods of Maryland. Captivated by birds, he began drawing them as a teenager. Gathering fundamental experience regarding avian anatomy, he studied and banded hundreds of birds over the years on California’s Farallon Islands through the Point Reyes Bird Observatory. His life has been a generous mix of art and travel as he illustrated numerous books, ornithological publications and countless private commissions.

Mt. Tam & Corte Madera Marshes - Birding in Marin Season 7 - Trip 4
2022-04-02 08:30 - 14:00 | CA, United States
Saturday, April 2, 2022
Birding with Jim White and Bob Battagin
8:30 AM to mid afternoon
Register for this field trip HERE
Registration for this trip opens at 8:00 AM on Wednesday, March 23. 8:00 AM. Limit of 15 fully vaccinated participants for this trip. There will not be a waiting list.
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 1or 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 (3.5mi) 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 Madeira 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 why 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. From Highway 1 in Stinson Beach or up 3.3mi from Tam Junction, take Panoramic Drive to it’s crest then go uphill 1 mile on Pantoll Road to the Rock Springs parking lot.

Each Fall and Spring the desert comes alive with migrating birds. Turkey Vultures are one of the earliest and most interesting of these migrants. Where are the going and what special habits and traits set Turkey Vultures apart from other migrating raptors? Are they really raptors or scavengers or both? Many of the secrets about Turkey Vultures, California Condors, and the migration of birds will be unveiled in this presentation.

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 3 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 afternoon 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.
