Aerial survey of Puget Sound area; no nesting Caspian terns observed at former colony sites in Port of Bellingham, Dungeness Spit, Bremerton Shipyard, or Port of Tacoma; Caspian terns observed roosting at a number of sites in the survey area, no nesting confirmed; during the same survey, aerial photos were taken of the double-crested cormorant colonies at Smith Island, the Snohomish River, and Drayton Harbor to estimate colony size

No Caspian terns nesting at the abandoned Georgia-Pacific mill site in the Port of Bellingham; nest dissuasion materials (silt fencing, fishing line, and flagging) were erected by the Port at the site prior to the 2011 breeding season to prevent tern nesting due to planned environmental cleanup of the site, which included the area used by nesting terns in 2009-2010

No Caspian terns nesting at the former colony site at the Puget Sound Naval Shipyard in Bremerton; terns nested (100-500 breeding pairs) on warehouse rooftops within the shipyard during 2003-2007; nest dissuasion materials (cones and flagging) were erected at the site in 2008 and have been successful in keep terns from nesting at the site ever since
