A perfect after-dinner bird search, we'll observe roosting behaviors, bed-time bird song, and more.

Field TripRadio Road by Bike
Saturday, August 27, 9:00am - 11:30am

High tide brings many shorebirds to roost at the Radio Road ponds in Redwood Shores. On this biking trip, we'll enjoy these birds, then ride the bike trails over to several nearby ponds and parks. Expect a nice array of shorebirds, the first of the returning winter ducks, and hopefully some songbird migration. 3-4 miles of biking in total. Heavy rain cancels. Any bike is fine, but you should come prepared with binoculars, water, sunscreen, warm clothes, and snacks. Helmets are required.

Directions: Meet by the dog park on Radio Road in Redwood Shores. Once Radio Road hits a T at the ponds, turn right to find parking by the dog park.

Field TripHawk Hill
Tuesday, September 13, 11:00am - 2:00pm

There has been an official raptor count in the Marin Headlands for more than 25 years. Peak migration lasts from mid-September through mid-October. Robbie Fischer has been a Hawkwatch volunteer for ten years. We will enjoy the spectacle and attempt to identify raptors as they fly by Hawk Hill. Here
is the Golden Gate Raptor Observatory website for additional background

Directions: Cross the Golden Gate Bridge and take the second exit, Alexander Avenue. Get in the left lane following signs that read "101 San Francisco." Turn left at the stop sign and cross under the freeway. Turn right onto Conzelman Road and drive 1.8 miles to Hawk Hill. Park alongside the road at the top of the hill, just before the road becomes one-way. Walk up the west side of Hawk Hill past the locked gate. It's just a few hundred feet to the summit. Bring binoculars, lunch and a chair if you like.

Field TripRarely Birded Spots in San Mateo County - Coal Creek Open Space Preserve

Wedged between the better-known Russian Ridge, Monte Bello and Windy Hill Preserves, Coal Creek is one of the least-known Open Space Preserves in the county. Join us for this leisurely 2-mile round-trip hike. We will be searching the skies for migrating raptors, and the edges along the old Alpine Road (now a hiking trail) for migrating passerines. Bring your camera for extraordinary views, too!

Field TripSeeking Vagrants at Point Reyes National Seashore
Saturday & Sunday; October 1 & 2

RSVP required no later than 8/22/2016 Trip limited to 12 participants.

Join us for spectacular birding at one of the best locations in the country! In early October fall migration is in full swing, and this is peak time for arrival of vagrant species that may have been blown off course. Our trip will focus on looking for any vagrants that have been previously reported, as well as visiting most of the well-known vagrant "traps" to find our own! Certain species of wood warblers reliably appear every fall: American redstarts and Palm, Blackpoll, Prairie, and Chestnut-sided warblers are some of the most "common" vagrants, but almost anything can turn up. With a supporting cast of returning winter visitors, this is an amazing place to spend a fall weekend! This trip will start with dinner on the evening of Friday Sept 30.

Due to the extremely low availability of hotel rooms in early October, please confirm your participation to Adam Dudley ( by August 22 at the latest.
