Registration for this trip is required. Registration opens March 12 at 8:00 AM.

Beginning and experienced birders are invited to join Rich Cimino and others to bird the park. This year we will be birding the Olompali Park two days after the Spring Equinox. It’s always an exciting time to birdwatch at Olompali State Historic Park which occupies parts of two blocks in the Marin County Breeding Bird Atlas II survey. Four MAS members who are surveying the park will be with us on the outing.

Early spring arrivals should be on hand as we walk the old ranch road to the park’s reservoir. Olompali State Park features oak savanna, open grasslands and riparian habitat: There is a good assortment of species, raptors, flycatchers, swallows, vireos, warblers, woodpeckers, nuthatches, thrushes, and orioles. Be early, the field trip will start at 9 AM in the parking lot. Rain cancels.

DIRECTIONS: Exit Hwy 101 at Atherton Ave/San Marin Dr in Novato. Follow the signs to Olompali State Historic Park. A right turn onto the Old Redwood Hwy frontage road will take you to the park. There is an $8 parking fee.

Registration for this trip is required. Registration opens Wednesday, March 22 at 8 AM. 

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 three 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 after- noon 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.

DIRECTIONS: From Hwy 101 in north San Rafael take Lucas Valley Rd west 10.3 miles then right turn onto Nicasio Valley Rd for 0.5 miles and park near the baseball field, the center of town. For GPS use 1 Old Rancheria Rd Nicasio, the address for the Rancho Nicasio Restaurant. Meet at ball field in Nicasio.

Birding with Sande and Bob Chilvers 

All participants are welcome to join this trip. No registration required. 

Beginning birders are especially welcome on the first Thursday of each month for a leisurely walk around the Las Gallinas ponds. Join our friendly leaders as we search for waterfowl, waders, songbirds, raptors, and shorebirds. Bird enthusiasts of all levels 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 the group is easy to find. 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. Meet the group by the bridge just past the parking lot. There is an outhouse in the parking area for public use.

Registration for this trip is required. Registration opens April 26 at 8:00 AM.

Join Jim and Bob for a field trip to the gentle slopes of Mount Burdell where we’ll listen to and observe the impressive variety of songbirds that make this area their springtime home. Species we might see include Lark Sparrow, Ash-throated Flycatcher, Bullock’s Oriole, Lazuli Bunting and Grasshopper Sparrow, among may other possibilities. In the afternoon, we plan to continue birding at Stafford Lake or Rush Creek.

This will be a moderate hike with many opportunities to look at birds and spring wildflowers. Wear comfortable walking shoes and layered clothing. Bring water and snacks. We will meet at the end of San Andreas Drive in Novato.

DIRECTIONS: Take Hwy 101 to Novato, exit at the San Marin Dr/Atherton Ave exit. At the end of the exit ramp, turn left (west) on San Marin Dr. Go approximately two miles and turn right on San Andreas Dr. Drive nearly to the end of the road and park on the street. No restrooms available.

Birding With Josiah Clark
Register HERE for this Field Trip 

Registration is required for this trip. Registration opens May 3^rd at 8:00 AM. 

The Presidio, part of the Golden Gate National Recreation Area since 1972, provides an excellent case study for the human and wildlife interface in San Francisco. Consulting Ecologist and San Francisco native, Josiah Clark, will share with us both the challenges and opportunities for wildlife and habitat preservation he has observed here. While the area has benefitted from the protection of the National Park Service and increased funding for special restoration projects, there have also been accompanying challenges brought about visitors, dogs, pathogens, and invasive plants that have all become more numerous as visitation to the area has dramatically increased.

We’ll meet Josiah at the Baker Beach Parking Lot, then travel on foot to Logos Valley, Mountain Lake Park, and the Presidio Hills before returning to Baker Beach. We’ll watch for signs of seasonal transitions in the area as wintering birds depart and the breeding season begins. A secondary focus for the trip will be habitat plants, some unique to the Franciscan scrub habitat, that Marin birders may not have seen. Heavy rain cancels.

DIRECTIONS: From Marin take Hwy 101 south to Merchant Rd. (Exit 439, first exit after the bridge) toward 25th Ave. in San Francisco. From Merchant Rd. turn right onto Lincoln Blvd. Next, turn right onto Bowley St. and right again onto Gibson Rd. Park in the Gibson Rd. parking lot. Parking is limited here, so ride with a friend if possible.

Registration is required for this trip. Registration for the Bear Valley/Five Brooks trip will be open starting on May 24 at 8:00 AM.

Join Jim and Bob on this trip as part of their yearly series of Marin walks. We will start our day at Bear Valley in search of nesting birds. Next, we’ll travel to Olema Marsh and Whitehouse Pool for a look at some different habitats. Our final stop of the day will be Five Brooks where we have a chance of finding Wood Duck at the retired logging pond. We will also look for birds in the Douglas Fir forest.

DIRECTIONS: From Hwy 101 take Sir Francis Drake Blvd toward Point Reyes for about 20 miles. At Olema turn right onto Hwy 1.
In 600 feet, turn left onto Bear Valley Rd. In approximately 0.5 mile, turn left at the entrance to Point Reyes National Seashore Headquarters at Bear Valley. We will meet at the picnic tables near the parking lot.

Birding with Rich Cimino and Janet Bodle

All participants are welcome to join this trip.  No registration required.

Join us on King Mountain for a bird walk that welcomes beginners as well as experienced birders. This accessible Preserve, rising above the main streets in Larkspur, is frequented by hikers, but not so much by birders. Janet and I survey King Mt. as part the Marin Audubon Breeding Bird Atlas project. We would like to introduce Marin Audubon birders to this location.

It's breeding season so any of the breeding migrants are probable, such as Lazuli Bunting, Black-throated Grey Warbler, and Yellow Warbler. Resident birds such as Wrentit and Pileated Woodpecker have been seen recently.

While the steep trail provides some excellent views, it can get quite warm. Bring liquid and wear a wide brimmed hat.

Directions from the corner of Magnolia Ave and Ward St in Larkspur: coming from north, turn right on Ward (left from the South), right on Hawthorne Ave, left on Willow Ave.  Park and meet at trail head gate (Citron Fire Rd.) on Willow Ave.

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.

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.

Registration required for this trip. Registration opens on July 27 at 8 AM on our TicketBud Site.

Meet at Sky Trailhead, near the crest of Limantour Rd. Directions below.

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, Steller’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.

Register HERE for this Field Trip

Registration required for this trip. 15 Participants max. Registration opens on August 13 at 8 AM.

Join William and David for the first of four fall migration field trips at Rodeo Lagoon. This is their long-time “patch,” which never seems to disappoint birders with daily variations in species and the chance of an unusual sighting. On this trip, our group will be targeting Elegant Terns and Parasitic Jaegers, migrating shorebirds, and western passerine migrants including warblers. We will begin the morning with a Sea Watch at 7:30 AM from Rodeo Beach. 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.

9:00 AM – 2:00 PM
Leader: Rusty Scalf

All participants are welcome to join this trip. No registration required.

We will bird the coastal scrub, lagoons, and ocean. We hope to find migrant shorebirds and resident Snowy Plovers. Abbott’s Lagoon has historically been good for Baird’s Sandpiper and we may get lucky. Meet at 9am at the Abbotts Lagoon parking lot (bathrooms but no water). Bring scope, liquids, lunch. Plan on walking 4 miles round-trip; relatively flat but trail consists partially of sand. Prepare for wind.

DIRECTIONS: From Point Reyes Station on Hwy 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. Carpool if you can.

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.
