Field Tripbeginner and family walk Bedwell Bayfront Park, Menlo Park
Saturday, December 3, 10:00am - 1:00pm

If you are just starting to dip your toe in the duck pond and would like to learn about ducks, shorebirds, what the Pacific flyway is and how our region features in it, then join us for an early winter look at what birds have arrived so far. There should be land birds to see, too. This trip is for beginning birders and those trying to remember the ID skills they learned last winter.

Directions: Take Marsh Road exit from Highway 101 and go Bay-ward straight through traffic light at Bayfront Expressway and Haven Avenue into the park. Meet in the parking lot (by the restrooms). Entrance is free.

Leader:Chris MacIntosh, 650-839-1523.

Field TripPillar Point Harbor
Wednesday, December 7, 9:00am - 12:00pm

Pillar Point is a hot spot for birding year-round. We should find a variety of resident birds and wintering shorebirds. Most of the walking will be on fairly level dirt trails, but if time permits, we may hike up onto the bluff top for a better view out to sea. Scopes will be useful here, so if you have one, bring it along. A primitive restroom is available at the parking lot.

Directions: The harbor is located just west of Coast Highway One, 18 miles south of San Francisco and 4 miles north of Half Moon Bay. From Coast Highway One, turn west at the stoplight at Capistrano Road and continue along the north side of the harbor to Prospect Way. Turn left onto Prospect, then a brief jog right on Broadway, to an immediate left on Harvard Avenue. Proceed through the boat yards to the end of Harvard Avenue, then turn right onto West Point Avenue, which curves around a marshy area and heads uphill to an Air Force Radar Facility. Meet at the "West Shoreline Access", popularly known as the parking lot to Mavericks, just below the radar station.

Leader: Donna Pomeroy

Field TripCowell-Purisima Trail
Saturday, December 10, 9:00am - 12:00pm

This morning's field trip will explore Cowell-Purisima Trail. We will be looking for raptors and grassland birds like sparrows and meadowlarks. Ocean views provide good seawatching opportunities for sea birds. This area features the coastal terrace prairie habitat, similar to Wavecrest and Blufftop parks further north in Half Moon Bay. At the turnaround point of our walk, there is a good riparian area where we can search for wintering warblers. This trip would be especially appropriate for photographers - both new and experienced - because of the sweeping vistas and hawks in flight. The plan is to walk a 4-mile roundtrip to the creek and back. The walk is flat except for the last descent into the creek area and return ascent back to the flat trail. There are restrooms at the parking lot. Heavy rain cancels.

Directions: meet at the parking lot on California Route 1, about three miles south of 92, across from Bob's Produce Stand.

Leaders: Malia DeFelice and Chris Hayward. Contact: 650-346-2009 (call if you are running late or lost) Heavy rain cancels

Field TripBest of San Mateo Bayside Winter Birding (RSVP required)
Saturday, December 10, 12:00pm - dusk

Join us for spectacular winter birding in San Mateo County! Early December is peak time to see most of the wildfowl, shorebirds, raptors and songbirds that spend the winter with us. The exact itinerary will be flexible and based on birds that have been reported over the previous few days. But expect to visit sites such as Redwood Shores and Foster City Lagoons, Nob Hill Pond, Radio Road, and Coyote Point, finishing the day at Bair Island around dusk. Birds such as Short-Eared Owl, Barrow's Goldeneye, Harlequin Duck, Greater White- Fronted and Cackling Geese, Eurasian Wigeon and Loggerhead Shrike may join our more regular winter visitors. This trip can be combined with the morning SAS trip to Cowell-Purisima Coastal Trail (led by Malia DeFelice and Chris Hayward) or enjoyed on its own.

Leader: Please register your interest with Adam Dudley at Trip limited to 14 participants.

Additional Field Trips will be added as the information becomes available.
