Heron's Head Park
Location: San Francisco
Trip Leader(s): Karen Vandergrift
Host: Jane Medley, janermedley@gmail.com, 559-760-1551
Start Date: Thursday, February 23, 2017
Start Time: 9:30 AM
End Time: 12:30 PM
Description: One of only a few wetlands on the city of San Francisco's shoreline, Heron's Head Park is a hidden gem: a 22-acre open space and thriving wildlife habitat that attracts more than 150 bird species every year. Born in the 1970's when the Port of SF began filling this location to construct what was to be the Pier 98 shipping terminal, the project was never realized. Over years of settlement and exposure to the tides, a salt marsh emerged, attracting shorebirds, waterfowl, and aquatic wildlife to this unique location. This will be an interpretive walk about the wildlife and ecology of San Francisco Bay and we will travel on flat ground. We expect a large variety of waterfowl, shorebirds, and maybe a rarity or two. Beginning birders are welcome! Bring binoculars, sunscreen, a hat, and water . . . and a spotting scope if you have one. Heavy rain cancels. DIRECTIONS: Meet at the parking lot on the corner of Jennings Street and Cargo Way, just across the street from Bay Natives Nursery. For GPS, use 10 Cargo Way, San Francisco, CA 94124, the address for Bay Natives Nursery.

Skaggs Island and Hudeman Slough
Location: Sonoma County
Trip Leader(s): Murray Berner
Host: Jane Medley, janermedley@gmail.com, 559-760-1551
Start Date: Saturday, February 25, 2017
Start Time: 8:45 AM
End Time: [not specified]
Description: Murray Berner led trips for Napa-Solano Audubon for many years and authored the Solano Co. Breeding Bird Atlas. Murray knows the marshes well and has access to Skaggs Island, closed to the general public. The Island, a former naval facility, is now part of San Pablo Bay National Wildlife Refuge, an addition of more than 3000 acres. February is peak season for raptors, including Golden Eagle, Rough-legged Hawk, Prairie Falcon, and Burrowing Owl, plus dozens of kites and harriers. Black Rail is resident and at times vocal. Songbirds flock in the former residential area, harassed by Merlin and Accipiters. Allen's Hummingbird will be displaying among the eucalyptus. We will meet at the south entrance to Skaggs Island off of Hwy 37 and travel by car across the island, stopping to bird along the way. Some birders may wish to leave when we reach the island's north gate. Interested birders may continue with the group to Hudeman Slough where we will bird on foot. Dress in layers and sturdy shoes and bring lunch and water. Field trip ends mid-afternoon. Heavy rain cancels. DIRECTIONS: Take Hwy 101 north to Hwy 37E. At the intersection with SR 121 (Sonoma Raceway), continue straight on Hwy 37 for 3.8 miles and turn left at Skaggs Island Road. No restrooms available.
