The last comprehensive treatment of the birds of Washington State was by Jewett et al. (1953). Since then several studies have been published (Alcorn 1962; Larrison and Francq 1962; Larrison and Sonnenberg 1968; Wahl and Paulson 1971, 1972, 1973, and 1974) and more than fifty species not cited by Jewett et al. have been attributed to the state’s avifauna. However, no systematic review of these attributions and no compilation of relevant bibliographic material has been attempted since 1953.
