Chris Anderson: "Management of Common Loons in Washington State," WOS Monthly Meeting, May 5, 2025

The Common Loon (Gavia immer) was known to be a fairly common breeding species both east and west of the Cascades as recently as the nineteenth century. Records indicate that Washington’s Common Loons were nearly eliminated due to sport shooting, loss of habitat and other factors including lead poisoning. A WDFW survey in the early 1980s found only two nesting pairs. Currently the Common Loon is listed in Washington as a "State Sensitive" species, with those on the east side doing better than those on the west side of the state. In his presentation, Chris described the challenges faced by the state's tenuous population of Common Loons, and framed the cooperative conservation efforts dedicated to managing this species in Washington, with notes on territorial birds local to King County. Chris D. Anderson is the District Wildlife Biologist with Washington Department of Fish and Wildlife (W.D.F.W.) for the King County area. The district is unique in being the most urban in the state – populated by many species of wildlife as well as one-third of the humans in Washington. Chris presented this talk at the Monthly Meeting of the Washington Ornithological Society ... "virtually" via Zoom, on May 5, 2025. We wish to acknowledge and thank Daniel and Ginger Poleschook for their long-term support of Common Loons, and their wonderful photography.
