Marin’s Declining Shorebirds
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.

Sky Trail and Limantour Beach – Birding in Marin
Birding in Marin, Season 9 – Trip 8 Saturday, August 3, 2024 8:30 AM – 3:00 PM Birding with Jim White and Bob Battagin Register HERE for this Field Trip Registration required for this trip. Registration opens on July 24 at 8 AM. 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 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. Shorebirds too, some already back from their breeding excursion to the Arctic, may gather 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.

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.

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.

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.

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.
