The Pacific Flyway is one of four major North American migration routes for birds, especially waterfowl, and extends from Alaska and Canada, through California, to Mexico and South America. The Sacramento Valley plays a significant role within the Flyway, providing crucial habitat for these traveling birds. This unique region is not only a haven for waterfowl but also plays an essential role in Northern California’s integrated water system.

The Sacramento Valley stands as the most important wintering area for waterfowl along the Pacific Flyway. Migrating birds depend on this region to rest and feed during their annual journeys. In addition to the various species of waterfowl, the Valley also supports raptors, shorebirds, and numerous other species that rely on this habitat year-round.

Every winter, the Sacramento Valley welcomes over 1.5 million ducks and 750,000 geese to its seasonal marshes. These birds migrate from as far away as Alaska, Canada, and Siberia, making the Valley one of the most prominent wintering sites for waterfowl in the world. The habitat supports approximately 44% of wintering waterfowl using the Pacific Flyway.
