Pacific Flyway Project, 1988-93: complete survey of shorebirds in the western United States.
What we learned: This provided the first ever baseline data on shorebird use of the Pacific Flyway.

Coastal CA Shorebird Survey 2006 and 2007: repeat survey at other major coastal California estuaries: Crescent City, Humboldt Bay, Bodega Harbor, Tomales Bay, Pt. Reyes Estero, Bolinas Lagoon, Elkhorn Slough, Morro Bay, Pt. Mugu Lagoon, lower Ballona Creek, Upper Newport Bay, and Seal Beach National Wildlife Refuge.

What we learned: San Francisco Bay's critical significance to wintering shorebirds confirmed! 74% of all 482,784 birds counted amongst the California estuaries were found in San Francisco Bay!
Some species have declined and some have decreased Decreasing species: Marbled Godwit, Dunlin, and Western Sandpiper.
Increasing species: Long-billed Curlew, Willet, and Least Sandpiper
We also noted a change in where birds are found- more shorebirds are using the North SF Bay.

Why Continue Counting?
For habitat managers and the public: Documenting what parts of the bay shorebirds are using and the change in the number of each species using the bay, can help guide wetland restoration and conservation projects. It is also important for documenting the importance of enhancing habitat in the SF Bay and other California wetlands, for shorebirds.
For scientists: Establishing a shorebird monitoring program for San Francisco Bay and other parts of the West is critical to the understanding of how shorebird populations are doing along the Pacific Flyway. Additionally, resource managers require scientific guidance and ongoing feedback to successfully restore and manage for habitats that sustain diverse and abundant shorebird populations.
