Rodeo Lagoon – Marin Headlands
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.

Birds, Plants and Wildflowers of Mt. Burdell
Thursday, April 2, 2026 8:30 am – 1:30 pm Birding with David Edelson and Michelle Muir REGISTER HERE 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.
