Field TripFoster City
Saturday, November 22, 8:30am - noon

Explore the ins and outs of Foster City - the Shell Bar, Sea Cloud Park, Port Royal and other little known spots.  This will be a walking/driving field trip.  Dress in layers, wear good shoes and bring a scope if you have one.  Meet at the small parking lot at Port Royal and Rock Harbor Lane.

Directions: from Hwy 101, take Hillsdale Blvd. east.  Turn right on Edgewater Blvd. and follow to the second Port Royal turn.  Turn right on Port Royal and at the point were the road turns right, turn left in to the little parking lot at Rock Harbor Lane.  Rain cancels.

Field TripPescadero State Beach and Environs
Saturday, November 29,   9am - 1pm

We will meet at the furthest end of the second (middle) parking lot for Pescadero State Beach. This is the parking lot just south of the creek mouth. It does not require a fee. We will spend some time looking for shorebirds and seabirds from the bluff. We will then drive a short distance to a dirt parking lot at the intersection of Hwy 1 and Pescadero Rd. where we will journey into the marsh and walk along trails which will allow us to view waterfowl, herons, egrets, raptors and other marsh birds up close and personal. If time and energy allows, we will head over to Water Lane to look for land birds. Water Lane takes us to the "back" of the marsh and is a great spot for warblers in fall and winter. There are a wide variety of habitats in this park and we will hope to see quite a few species. Expect cool and breezy weather here, but warmer when we go inland. Restrooms are located at the first parking lot. Heavy rain cancels.

Directions: From Half Moon Bay, take Highway 1 south, about 15 miles toward Santa Cruz. As you approach Pescadero, you will see an extensive marsh on the east side of the highway and the second parking lot will be on your right, just after you cross the bridge over Pescadero Creek mouth. Heavy Rain Cancels

Field TripMillbrae Bayfront Park
Wednesday, December 3, 8:30am - 10:30am

Millbrae Bayfront Park is one of the best locations in San Mateo County to look for the endangered California Clapper Rail.  As high tide approaches at 9:30, we will have an excellent chance to see this normally elusive bird out in the open.  This is also an excellent location to view the large number of ducks and shorebirds that use this part of San Francisco Bay as a wintering ground.  Meet at the free public parking for the Marriott Hotel.

Directions: Bayfront Park is located at the corner of Millbrae Ave. and Old Bayshore. Take US 101 to the Millbrae exit, and go east. Where Millbrae Ave. ends, turn right onto Bayshore Hwy. Take your next available left (a turn lane is provided) into the Marriot Hotel's parking lot, and bear left. There are a handful of spaces set aside for Bayfront Park. There are a handful of overflow spaces in the Westin lot, which is the first right off of Bayshore after you turn off of Millbrae.

Field TripCowell-Purisima Trail
Saturday, December 6, 8:30am - 12:30pm

Work off those Thanksgiving meals with a long, but easy, hike along our sumptuous coast! This morning's field trip will explore the new Cowell-Purisima Trail, opened by Peninsula Open Space Trust last year. We will be looking for raptors and grassland birds like sparrows and meadowlarks. Ocean views provide good sea watching 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.
