Puget Sound Seabird Survey (PSSS) is a citizen-science survey organized by Seattle Audubon since the fall of 2007. PSSS empowers volunteer birdwatchers to gather valuable data on wintering seabird populations in Puget Sound. Over sixty sites are surveyed in central and south Puget Sound (Island, Jefferson, King, Kitsap, Pierce, Snohomish, and Thurston counties). All survey sites are visited within the same four-hour window on the first Saturday of each month (Oct-Apr), thus taking a synchronized "snapshot" of seabird densities on nearly 5 square miles of near-shore salt water (that's 2,200 football fields!). It is the only land-based, multi-month survey in central or south Puget Sound and it's 100% citizen science!
