Rodeo Lagoon – Marin Headlands
With spring migration coming to an end, we’ll be looking out for late migrants, including passing loons, shorebirds and scarcer 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 passerine migrants even at this late date. Join us for a Sea Watch at 7:30 AM or arrive later at 8:15 AM for a circuit of the lagoon. A brief mid-morning ‘coffee-stop’ is planned at the Headlands Center for the Arts. Your contribution for coffee via the onsite “tip-jar” would be appreciated. This field trip is less suitable for beginners.

David Ainley will introduce us to the incredible aquatic nature of these creatures, highlighting the foraging ecology and marine lives of penguins.
