FIFTH REPORT OF THE ALASKA CHECKLIST COMMITTEE, 2018-2022

摘要

The fifth report of the Alaska Checklist Committee adds 21 species to the Checklist of Alaska Birds from the five years 2018-2022, a net total that includes the addition of two species formerly maintained as subspecies—Stejneger's Scoter (Melanitta stejnegeri) and the Short-billed Gull (Larus brachyrhynchus)—and the deletion of one species (Northwestern Crow) currently maintained as a subspecies of the American Crow, Corvus brachyrhynchos caurinus. At the close of 2022 we recognize 541 species and 118 additional subspecies as occurring, or having occurred, naturally in Alaska.
