Birding with William Legge and David Wiechers
REGISTER HERE
Registration is required for this trip. Registration opens on Sunday, March 15 at 8 AM.
Limit of 15 participants for this trip.
With early spring migration underway will be looking out for migrant wildfowl, grebes, loons, gulls, and passerines. As usual, the weather will dictate our focus with onshore northwest winds ideal for spring sea watches, while offshore easterly winds promise a good selection of late winter and early summer passerine migrants. Join us for a Sea Watch at 7:30 AM or arrive later at 8:00 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 signal 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.

Birding with Mark Clark
Registration is not required. 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 and swallows. 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. Meet the group by the bridge just past the parking lot. There is a portable restroon in the parking area for public use.

Registration is required. Registration opens Sunday, March 23 on 8 AM.
Limit of 15 participants for this trip
On this moderate 4-mile hike, we will look and listen for birds, and also stop to appreciate native plants and habitat, particularly wildflowers which should be in abundant bloom.
Mount Burdell, a Marin County Open Space Preserve located just west of Novato, is a hotspot of plant and avian diversity, with diverse oak woodlands, grasslands, serpentine outcrops and a vernal pool (Hidden Lake). Some of the birds we’ll hope to see include spring migrants like orange-crowned warblers, house wrens, lark sparrows, and Bullock’s orioles, as well as year-round residents like oak titmice, Bewick’s wrens, western bluebirds, and multiple species of woodpeckers. This trip is suitable for all levels of birders and plant enthusiasts.
We’ll meet at the San Andreas trailhead. To get there, exit Highway 101 at San Marin Drive, go west approximately 2.5 miles, turn right (north) on San Andreas Drive and go roughly .6 mile to the trailhead. There is parking along the road but no bathrooms or water. We are planning a 4-mile hike which includes some uphill and/or rocky sections where hiking poles might be useful. We recommend hiking shoes or trail shoes with good traction. Please bring lunch/snacks, ample water, sunscreen, a hat, and of course binoculars.
