San Francisco is on the Pacific Flyway, a regular thoroughfare for migrating birds. And since there are an abundant amount of rich wetlands along the Bay Trail, you can see some pretty rare birds during the winter months. Below are some great places to spot them.
Please note: Harassing birds in any way violates the Migratory Bird Act and comes with fines. Be sure to give animals plenty of space and to use a long lens if you're photographing.

Arrowhead Marsh is rich with bird species in the winter, as migrating ducks and shorebirds find hospitable habitat in the marshes and shoreline of the park.
Arrowhead Marsh is part of the 741-acre Martin Luther King Jr Shoreline, just east of Oakland Airport. The park and wetlands have a natural beauty that is a striking contrast to the light industry and aviation surrounding the area.
A short walk from a parking spaces can render a vast landscape of bird-watching potential. If you have just a bit of time, head to the pier area of Arrowhead Marsh for a variety of birds sightings -- species depending on high or low tides and time of day.

Diverse habitats and varied terrain constitute Coyote Hills Regional Park. In the lowlands of the park, visitors can enjoy a boardwalk and trails through marshlands that, in the winter, are home to a large variety of migrating ducks and shorebirds.
In the upper reaches of the park, you can traverse trails across the hills for panoramic views of San Francisco Bay, as well as frequent sightings of the area's raptor population (hawks and even occasional eagles).
The visitor center has a natural history display of local wildlife, in addition to information about the area's historical residents, the Ohlone peoples.

Crissy Field and the marsh are stunning examples of habitat restoration. The original terrain -- a vibrant salt marsh -- was destroyed through other applications. The land was used for the Panama Pacific Exhibition in 1915 and later as a military aviation field.
In 1997, restoration began with environmental remediation, followed by a military-post-to-park transition that involved the planting of 100,000 native plants and a community of volunteers.
The primary access to the marsh and to the bird watching possibilities is via a boardwalk you can access from the East Beach parking area or from Crissy Field Center.

Don Edwards refuge is a network of parks along the Pacific Flyway, a primary migratory route for birds.
The refuge is 30,000 acres of marsh, salt ponds, mud flats and shoreline, hosting a wide variety of shorebirds and waterfowl.
The Don Edwards website has a full-color brochure (pdf) for download. The brochure describes the refuge and wildlife, as well as information on fishing and other recreation in the refuge.
There's a public visitor center in Fremont and an Environmental Educational Center in Alviso.
Animal lovers should be aware that hunting is permitted in some parts of the refuge. Areas near the visitor centers, however, are removed from hunting zones.Continue to 5 of 11 below.

Lake Merritt is an urban park with many birds tamed by virtue of their association with humans. But the lake still provides refuge for a variety of wild and migrating species of ducks. Founded in 1870, Lake Merritt is the oldest wildlife refuge in the country.
Between Lake Merritt and Lake Merritt Channel Park (west of the lake), you're bound to encounter Buffleheads and Goldeneyes as well as many cormorants who rest on the floats strung across the east end of the lake.
For learning about our resident and migrating birds, for educating children about local wildlife, and for up-close picture taking, Lake Merritt offers some incredible opportunities.

The salt marsh and ponds here are part of a restoration plan by Las Gallinas Sanitary District. The solar-powered wastewater treatment plant has included wetlands reclamation as part of its land management.
There's a dirt trail that circumnavigates the ponds and also connects with the Bay Trail. (See the Las Gallinas profile for links to Bay Trail maps.)
A variety of bird species dabble along the shorelines and in the ponds, including numbers of migrating shorebirds and ducks. You may see egrets, herons, phalaropes, American Avocets, Black-Necked Stilts, and Killdeer, as well as raptors and song birds.Continue to 9 of 11 below.

The Palo Alto Baylands preserve is almost 2000 acres of marshland, with 15 miles of trails and a variety of habitat areas, from freshwater to saltwater and estuarine.
The marshes and ponds provide sightings of a variety of ducks and shorebirds, as well as American White Pelicans -- not as widely seen as the more common Brown Pelicans of the Bay Area.
The Lucy Evans Baylands Nature Interpretive Center (in the park) offers free exhibits, drop-in nature walks, and other educational opportunities.
The Stanford website has a good map of the Palo Alto Baylands area, showing the various trails through the marsh and wetland habitats.

Point Isabel Regional Shoreline is part of Eastshore State Park -- which is actually a series of parks along the East Bay shoreline. The park connects Richmond Bay Marina with the Albany Mudflats with Cesar Chavez Park in Berkeley with Emeryville Crescent at the Bay Bridge.
Not only does Eastshore State Park offer a variety of marshes and estuarine habitat areas, the parks are linked by a walking and biking trail that's part of the expanding Bay Trail.
North of the Point Isabel dog park, Meeker Slough (along the shoreline trail) offers numerous bird-watching points, especially for shorebirds and ducks that congregate here, depending on the levels of the tide.

The Richardson Bay Audubon Nature Trail is a short (less than one mile) trek along the bay as well as through forest and grassland habitat.
You can follow the trail in a loop on the Audubon grounds, or simply head straight out to Lani's Beach to view the birds on the bay and along the shoreline.
Bay birds include sandpipers, terns, pelicans, ducks and many water species. In the forest and riparian sections of the trail, you'll find a variety of warblers, hummingbirds, towhees, mockingbirds and others.
