The Ponds at the Las Gallinas Valley Sanitary District (LGVSD)
Location: San Rafael, CA
Trip Leader(s): Susan Kelly & David Sexton & Greg Haskins
Host: Jane Medley,, 559-760-1551
Start Date: Thursday, May 4, 2017
Start Time: 9:00 AM
End Time: 12:00 PM
Description: Beginning birders are especially welcome on the first Thursday of each month for a leisurely walk around the Las Gallinas ponds. The area includes two treated wastewater storage ponds, a freshwater pond with islands for nesting habitat, and several miles of flat levee trails. It attracts thousands of birds, including waterfowl such as ducks, geese; waders such as herons and egrets; songbirds; as well as varied raptors. Birders were fewer than usual on our April walk (probably the rain), but our group enjoyed good views of a Virginia Rail and Sora along with numerous singing Marsh Wrens. Even our group's youngest birder, two-year old Sada, spotted birds -- a large overhead flock of what were probably crows. Each month seems to yield an interesting, and often unexpected, species, so come assist us in our search. We welcome bird enthusiasts of all levels. We all help each other to find and identify the birds, and there are usually several experienced birders to assist. You don't even have to arrive on time because we spend the first 30-60 minutes studying the birds around the first pond and the group is easy to find. Heavy rain cancels. DIRECTIONS: From Hwy 101, exit at Smith Ranch Rd. Drive east on Smith Ranch Road toward McInnis Park. Turn left immediately after crossing the railroad tracks and drive about .5 mile through the LGVSD gates and into the parking lot at the end of the road. Meet the group by the bridge just past the parking lot. There is an outhouse in the parking area for public use or you can use the bathrooms at nearby McInnis Park.

Start Date: Friday, May 5, 2017
Start Time: 8:15 AM
End Time: 3:00 AM
Description: Pine Flat Road is located northeast of Healdsburg and has long been a local birding mecca. This road winds through open oak woodlands, gray pine forest, grasslands, and beautiful chaparral. It reaches an altitude of 2,279 feet. Bird specialties include Mountain Quail, Bell's Sparrow, California Thrasher, and Purple Martin. There are also possibilities of seeing Lazuli Buntings, Rufous-crowned Sparrows, Western Tanagers and many more spring specialties. You may also want to bring some wildflower books. Bring plenty of water, lunch, snacks, binoculars and a field guide or app. No restrooms available. However, the Jimtown Store is available at the end of the day. Heavy rain cancels. Directions: Take Hwy 101 north past Healdsburg to the Lytton Springs Rd. Exit toward Alexander Valley. Turn right on Healdsburg Ave. for about 0.7 miles. Turn left on Alexander Valley Rd. for 3.8 miles to Pine Flat Road. Alexander Valley Road is Highway 128 at this point. Not far past the Jimtown Store, Highway 128 makes a right angle turn to the south. Go straight ahead at this sharp curve to cross over to Pine Flat Road, which continues east. Be very careful at this intersection. We will meet on the corner of Pine Flat Road and Red Winery Road at the bottom of the hill at 8:15 to arrange carpools to the Mayacamas. Allow at least 1½ hours from central Marin.

Miwok Meadows
Location: China Camp State Park
Trip Leader(s): Matt Perry and Susan Kelly
Host: Jane Medley,, 559-760-1551
Start Date: Wednesday, May 10, 2017
Start Time: 8:30 AM
End Time: 11:30 AM
Description: Miwok Meadows, on the east side of China Camp State Park, is somewhat off the beaten path and under-birded, but it is one of Matt Perry's favorite regular birding spots. Consisting of a relatively short, easily hiked loop, it offers a range of habitats, including the bay, marsh, oak savannah, and denser woods. Frequent highlights include Osprey, many woodpeckers, turkeys, many swallow and swift species, and usual woodland birds. Less common finds include Pileated Woodpecker, and Blue-gray Gnatcatcher. Rarer birds, but not unheard of, include both Ridgway's Rail and Black Rail. In spring the trail should be filled with lovely birdsong and bustling activity -- and great views of yet another beautiful Marin landscape. Following our walk at Miwok Meadows, we will cross the street and hike the bay and marsh loop around Turtle Back Hill (.75 miles easy) with Susan Kelly. We'll watch for wildlife along this trail, which juts out into the salt marsh habitat along San Pablo Bay. This trail meets criteria for wheelchair access under the Americans with Disabilities Act. Directions: Take the Hwy 101 Exit onto North San Pedro Road. Follow North San Pedro Road approximately 2 miles to the Back Ranch Meadows Campground. There are two possible places to pay entrance fees depending on whether you want to park near the start or the end of our trip. If you wish to park near the starting location, turn right at the entrance to the Back Ranch Meadows Campground. Just past the campground kiosk, an Electronic Pay Station is located from which you can purchase a Parking and Trail Pass for $5 per vehicle, which includes trail access for all people in the vehicle. This pay station can accept credit cards or exact change. Continue 1.1 mile up the road to meet our group. If you wish to park near the ending location of our trip, continue on San Pedro Road approximately .5 mile past the campground and park adjacent to the roadside near Turtle Back Hill. On the right side of the road adjacent to the trailhead, there is a self-pay kiosk where you may purchase a Trail Only Pass for $3 per person. Exact change is needed at this "iron ranger" pay station. Walk approximately .2 miles to our meeting place at the Miwok Meadows Day-Use Area.

Tennessee Valley/Bay Model Art Exhibit

At approximately 10:30 AM we'll head to the Bay Model in Sausalito where we'll meet with artist Rita Sklar and view her watermedia paintings featured as part of the current "Vanishing Species exhibit. Rita's work highlights the vanishing birds and other wildlife of the San Francisco Bay Area and beyond. Her paintings depict the variation in shapes, colors, and patterns that birds present and are a reminder that like the proverbial canaries in the coal mine, the decline of wildlife is a wake-up call to take better care of our planet. Bring water, snacks, and binoculars. Restrooms are available. Directions: From Hwy 101, take the Stinson Beach exit. Turn left on Shoreline Highway in 0.1 miles. Turn left on Tennessee Valley Rd. in 0.3 miles. Take a slight right turn onto Tennessee Valley Road. We will meet at the parking lot at the end of the road for the hike.
