Join us aboard Dolphin Charters’ River Dolphin for a wonderful day of exploring the richness of the California Delta with naturalist David Wimpfheimer as our guide. Ronn Patterson, a Bay Area historian and naturalist, is captain of the River Dolphin and owner of Dolphin Charters. 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 this 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. 

There will be a waiting list. To assure a spot for yourself, we recommend booking your space asap as this is always a popular trip.  Those confirmed on the trip will receive directions to the Antioch Marina and other instructions the week before the trip.
