Washington State Department of Fish and Wildlife has been conducting bald eagle surveys on a statewide basis since 1980.

The survey effort was quite intense for the first decade, and has decreased in intensity as the eagle population has increased, so that survey dollars can be dedicated to species at greater risk. From 1980 – 1992, surveys were conducted in the early season (April) to identify active nests with incubating birds, and in the late season (June) to count the number of chicks produced. From 1992 – 1998, only the early season survey was conducted to identify active nests with incubating birds. The last annual statewide survey was in 1998.

Statewide surveys are now conducted at multi-year intervals. The last two statewide surveys were in 2001 and 2005. Additional information is provided in some instances from volunteers who are able to watch nests, or from other surveys that are conducted in the vicinity of nests.
