	year = {2010},
	note = {"Based on the best available data for the three Pacific coastal states and British Columbia during the periods ca. 1992 ... and ca. 2009, our best estimate of the average annual population growth rate (λ) for this population is 1.03, indicating that the population has grown at an average annual rate of about 3\% per year over the last two decades. This overall trend apparently reflects continued recovery of the Western Population due to various statutory and ecological factors during the latter half of the 20th Century, including inclusion of the species in the Migratory Bird Treaty Act, the banning of DDT, and the shift by the species toward increased use of artificial nesting habitats. Most of this population increase, however, can be attributed to increases in the numbers of breeding pairs in the Columbia River estuary and at a few inland sites, which currently account for approximately 41\% and 29\% of breeding pairs in the Western Population, respectively. Concurrently, numbers of breeding pairs in coastal British Columbia, northern Washington, and southern California have declined since 1987-1992." (from the Executive Summary)},
