Field TripPillar Point Harbor
Saturday, August 11, 8:00am - 11:00am

Pillar Point is a hot spot for birding year-round. We should find an interesting variety of birds. Most of the walking will be on a fairly level dirt trail, 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 boatyards 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" parking lot, popularly known as the parking lot to Mavericks, just below the radar station.

Leader: Donna Pomeroy

Field Trip"Bilingual" Pillar Point Bluffs – NEW DATE
Saturday, August 11, 8:00am - 11:00am

Join us for our inaugural bilingual/Spanish birding trip, led by State Park interpreter Alan Mata! The Bluffs at Pillar Point are an excellent place to get to know local common birds as well as look for early migrants. Resident sparrows, thrashers, finches and hummingbirds are joined by terns, cormorants, shorebirds and murres on the ocean. Sooty shearwaters could be numerous, returning elegant terns and Heerman's gulls could put in an appearance, and the chance of humpback whales close in to shore make for a potentially exciting morning! This trip is especially suitable for beginner birders and naturalists. Binoculars are useful, and bring a camera and a scope if you have them. Don't forget water and a sun hat!

Directions: We will meet at Pillar Point Bluff parking lot, along Airport Street in Half Moon Bay, directly opposite the Half Moon Bay airport.

Leader: Alan Mata. RSVP:
Please let Alan know if you need loaner binoculars when RSVP-ing.
