The Birds of Washington (hereafter BWA) is the first work since 1953 (when Birds of Washington State by Jewett et al. was published) to cover the status of Washington’s birds completely. The three editors contributed a large portion of the species accounts, but, all told, more than 40 authors played parts in writing the book. All 483 species recorded in Washington have individual species accounts, and separate sections in the back of the book treat introduced and hypothetical species (one of which, the Red-necked Stint, has since been confirmed in the state).
