Field TripfeeSan Pedro Valley Park
Thursday, April 28, 8:30am - 11:30am

San Pedro Valley County Park is a beautiful wilderness area located in the foothills of the Santa Cruz Mountains in the city of Pacifica. We will visit the Old Trout Farm Trail and the picnic groves. Expect to see or hear riparian breeders such as Black-headed Grosbeak, Swainson's Thrush, Wilson's Warblers and Orange-crowned Warblers.

Directions: Take SR 1 to the city of Pacifica, 10 miles south of San Francisco or 12 miles north of Half Moon Bay. Turn east on Linda Mar Boulevard. Drive for about two miles, to the end of Linda Mar. Turn right here on Oddstad Boulevard and make an immediate left into the Park. To park inside the Park there is a $6.00 fee. Seniors park free on non-holiday weekdays. We will meet at the Visitor's Center.

Field TripBurleigh Murray Ranch State Park
Wednesday, May 4, 8:00am – 12:00pm

Burleigh Murray State Ranch Park is a hidden treasure on the coast. It has very low visitor usage and a very high density of breeding birds. The only trail is the mile-long, old ranch road that leads to an historic and picturesque barn. The high number of singing birds will keep this walk at a slow pace. This is a great location to learn and practice birding by ear. Morning fog is common here, but it usually burns off and it can be warm and sunny.

Directions: We will meet at the lower parking lot to the Johnston House, located on Higgins-Purisima Road in Half Moon Bay. Higgins-Purisima Road begins just off of SR1, going east where Main Street ends. The Johnston House is the big white 1850s farmhouse on the hill. We will caravan to Burleigh Murray, which is 1 ½ miles up Higgins-Purisima Road from here.

Field TripBirding by bike on Cañada Road, Belmont/Woodside
Sunday, May 8, 8:00am to 10:30am

On this biking trip we'll enjoy the breeding songbirds that make May such a noisy month. We will bird the stretch of Canada Road from Route 92 to Edgewood Road, enjoying oak woodland, willow thickets, the Crystal Springs Reservoir, and some grassland. Expect to see and hear several species of flycatcher and warbler, as well as a mix of other local breeding songbirds. Cañada Road is closed to car traffic starting at 9am on Sundays, so the ride is relatively peaceful. 6-8 miles of biking in total. Any bike is fine, but you should come prepared with binoculars, water, sunscreen, warm clothes, and snacks.

Directions: We'll meet at the northern end of Cañada Road, just south of the intersection of Route 92 and Cañada Road. Parking is available along the sides of the road. Heavy rain cancels.

Field TripSan Francisco Watershed, San Mateo County
Sunday, May 15, Time TBD (Reservations required)

Join leader Ginny Marshall and SF Watershed docents on a walk in the San Francisco Watershed in San Mateo County. We will enter this restricted area off Highway 92 and walk about 5 relatively flat miles along the ridge top. This is a beautiful hike, mostly in the forest, and we will be alone on the trail. This walk is limited to 15 people.

You must RSVP to the leader at least two weeks before the walk as a permit will need to be issued with participants names. Bring lunch, water, layers and sun protection.

Field TripHorseshoe Lake (Skyline Ridge Open Space Preserve)
Saturday May 21, 8:30am hike will last 3 to 4 hours

This field trip has been cancelled due to issues resulting from a conflict with another event at this location.

Join Malia and Chris and explore Horseshoe Lake and vicinity as we search for spring birds such as Ash-throated Flycatcher, Lazuli Bunting, Black-headed Grosbeak and Pacific-slope Flycatcher and Western Tanager. We will hike through diverse habitat of chaparral, willows, and mixed forests. This easy hike will be 2 to 3 miles.

Field TripGazos Creek & Pigeon Point Lighthouse
Wednesday, June 1, 8:30 am -12:00 pm

Gazos Creek is prime location in the county to see and hear our summer resident woodland birds such as grosbeaks, warblers and thrushes. This lush coastal canyon, with its permanent stream and light traffic, is an excellent birding location. We will meet at the parking lot at the lighthouse and then carpool to Gazos Creek, since there is limited parking along the pullouts on Gazos Creek Road. When we return to our cars at the lighthouse, we will spend some time looking at the Pigeon Guillemots, other waterbirds and whales. Scopes will be useful at the lighthouse, when we look for seabirds. The weather at the lighthouse can be cold and windy; bring layers.

Directions: Take Hwy 1 south from Half Moon Bay for 20 miles. Turn right at the lighthouse and drive to the end of the road to the parking area.
