Volunteer to Count Vaux’s Swifts
September begins the fall migration of Vaux’s Swift through Marin County Marin Audubon and the Bay Area Vaux’s Swifts Working Group are expanding efforts to count Vaux’s Swifts and are seeking new volunteers with various abilities to join in the effort through this Workshop. This is part of a wide effort to understand the largely unknown movement and roosting patterns of Vaux Swifts. We invite you to join us for this exciting citizen science opportunity! Volunteers will engage with knowledgeable Vaux’s Swift counters/members of the Working Group who bring years of experience to share with newly-motivated birders. Volunteers will learn about and participate in refining the methods used to count these large congregations of Vaux’s Swifts and plan future counting activities. The Workshop has two parts: - Thursday, September 5th - 7PM - a meeting on Zoom at which you will hear an overview of the conditions at the overnight roost areas, efforts to count the swifts at this local site, and the various ways you can help. Register HERE for this Zoom Workshop Program: Welcome - Barbara Salzman, President Marin Audubon Society MC – Rich Cimino Presenters – Michael Helms, Rusty Scalf - Sunday, September 8 , 6 to 8PM A site visit to the Vaux’s Swift migration roost at Mc Near Brick Yard, San Rafael for on-site experience and guidance from experts. Contact Rich Cimino for more information: via email at or text 925-353-0266

The Ponds at Las Gallinas Valley Sanitary District
Thursday, September 5, 2024 8:30 AM to 12:00 PM Birding with Mark Clark All participants are welcome to join this trip. We welcome bird enthusiasts of all levels, especially beginning birders, to join leader Mark Clark on our monthly walk around the ponds at Las Gallinas. On our search we’ll be looking for waterfowl, waders, songbirds, raptors, rails and swallows. With fall migration underway, shorebirds are arriving from their nesting grounds and we are likely to spot some interesting species, so come assist in our search. The packed dirt paths around the ponds are wide, flat and easy to navigate. Heavy rain cancels 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.

Point Reyes Lighthouse to Drakes Beach – Birding in Marin
Point Reyes Lighthouse to Drakes Beach – Birding in Marin
Birding In Marin, Series 9 – Trip 9 Saturday, September 7th, 2024 8:30 AM to mid-afternoon Birding with Jim White and Bob Battagin Register HERE for this Field Trip Registration is required for this trip. Registration opens August 28 at 8AM. 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 “fly 15 degrees east of due south for 4 days.” Millions of recently fledged birds undertake a journey of 2,000-4000 miles, many without further parental guidance and without google. 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, but 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 ocean 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 in the distance sticking out 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 lighthouse then work our way back to Drake’s Beach for lunch and much more birding. Directions: Meet at 8:30 at the Light House 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.

Rodeo Lagoon – Marin Headlands
Rodeo Lagoon – Marin Headlands
Wednesday, September 11, 2024 7:30/8:15 AM to noon **See start time locations below Birding with William Legge and David Wiechers Register HERE for this Field Trip Registration required for this trip. Registration opens on September 1st at 8 AM. Join William and David for this third fall migration field trip at Rodeo Lagoon. This is their long-time “patch,” which never seems to disappoint birders with daily variations in species and a good chance of an unusual sighting. On this trip, our group will be targeting Parasitic Jaeger, migrating shorebirds and scarcer migrant passerines. We will begin the morning with a Sea Watch from Rodeo Beach at 7:30 AM. Those arriving later may join us at 8:15 AM for a circuit of the lagoon. A brief mid-morning ‘coffee-stop’ is planned at Headlands Center for the Arts and it would be appreciated if participants come willing to contribute via the onsite ‘tip-jar’ as a thank you to the Headlands Center for the Arts for accommodating our group. This field trip is less suitable for beginners. 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.

Vaux’s Swifts at McNear Brick and Block
Vaux’s Swifts at McNear Brick and Block
Friday, September 13th, 2024 6:00 to 7:40 PM depending on the weather Birding with Rich Cimino Register HERE for this Field Trip Registration is required for this trip. Registration opens September 3rd 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 decommissioned smokestacks provide an important communal roosting place for the swifts. Watching thousands of 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 7:09 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.

Audubon Canyon Ranch’s Cypress Grove Research Center
Audubon Canyon Ranch’s Cypress Grove Research Center
Tuesday, September 17, 2024 8:00 AM – 11:00 AM Birding with David Lumpkin Register HERE for this Field Trip Registration is required. Registration opens September 7th at 8AM. Join avian ecologist David Lumpkin, for a field trip to his work location, Audubon Canyon Ranch’s Cypress Grove Research Center. All levels of birding enthusiasts are welcome on this easy two-mile walk. Sightings on our walk to and along Tomales Bay at this time of year may include ocean birds if conditions are right (Jaegar’s come down the bay chasing the migrating terns around then), the occasional vagrant passerine, and an influx of interior breeders not seen in the summer. Other migrating shorebirds and waterbirds may be seen as well as the usual mix of coastal prairie species. Rain does not cancel. Directions: Address for Audubon Canyon Ranch’s Cypress Grove Research Center is 20545 State Hwy 1, Marshall, CA 94940 Going north on Hwy 1, look for a green metal gate (which will be left open) on the Tomales Bay side and a Cypress Grove sign. The gate is roughly a 1/2-mile north of Hog Island Oysters in Marshall (and the turnoff to the Marshall-Petaluma Rd.) and well before Nick’s Cove. Drive down the dirt road to where it splits, bear left, and park at the visitor parking lot.

Abbotts Lagoon and the Inverness Tennis Area – Birding in Marin
Abbotts Lagoon and the Inverness Tennis Area – Birding in Marin
Birding in Marin - Series 9, Trip 10 Saturday, October 5th, 2024 8:30 AM to mid-afternoon Birding with Jim White and Bob Battagin Register HERE for this Field Trip Registration required for this trip. Registration opens on September 26th at 8:00 AM. Abbotts 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 2 miles (some in sand). 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. After leaving Abbotts Lagoon, 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 Abbotts Lagoon parking lot is on the left, in about 3 miles. Car Pool if you can, allow 1.5 hours from San Rafael.
