Description: We will start with a close look at the Ellis Creek "Polishing Ponds" (that are "relatively clean but I wouldn't go for a swim in them"), then check the adjacent fields, the riparian corridor along Ellis Creek, and the tide flats towards the Petaluma River. Next we hike over to the Shollenberger dike. The entire area is excellent for wintering waterfowl (possible Blue-winged Teal), rails (four species possible), waders, shorebirds, and sparrows. Expect to hike maybe two or three level miles. DIRECTIONS: Going north on Hwy 101 from Marin, take the second Petaluma exit, which is Route 116 (Lakeville Highway). Go east about one mile to South McDowell Blvd. (4th traffic light) and turn right. At the curve turn right on Cypress and drive straight to the east end. Meet in the parking lot. Bring a lunch.

The boat is very comfortable and the outer decks provide views over the levees of the amazing array of birds found in the Delta during the winter. This rich area hosts a wide variety of raptors including Swainson's Hawks, Peregrine Falcons, and Great Horned Owls. Large numbers of shorebirds, Sandhill Cranes, Tundra Swans, Snow, Canada and White-fronted Geese, ducks, as well as gulls, terns, bitterns and passerines make the cruise a highlight for birders. Uncommon mammals such as beaver, river otter, and mink often add interest to the cruise. We also will learn about the history, ecology and politics of the levees and the Delta as we travel through its meandering channels. The trip is limited to 25 participants and the cost is $105.
