This is the 17th supplement since publication of the 7th edition of the Check-list of North American Birds (American Ornithologists' Union [AOU] 1998). It summarizes decisions made between April 15, 2016, and April 15, 2017, by the AOS's Committee on Classification and Nomenclature—North and Middle America. The Committee has continued to operate in the manner outlined in the 42nd Supplement (AOU 2000). Changes in this supplement include the following: (1) four species (Melanitta nigra, Rallus longirostris, Thalassarche eremita, and Acrocephalus dumetorum) are added to the main list on the basis of new distributional information, including one species transferred from the Appendix; (2) nine species (Tadorna ferruginea, Rallus aquaticus, Charadrius veredus, Corvus frugilegus, C. cornix, Sylvia atricapilla, Zoothera aurea, Anthus pratensis, and Acanthis cabaret) are added to the main list because of a change in the geographical coverage of the Check-list (inclusion of Greenland), including six species transferred from the Appendix, and the status codes for four species (Anser brachyrhynchus, Pluvialis apricaria, Turdus pilaris, and T. iliacus) are changed for the same reason; (3) four species (Eugenes spectabilis, Loxia sinesciuris, Melozone cabanisi, and Junco bairdi) are added to the main list due to splits from species already on the list; (4) the distributional statement and English name of one species (Aulacorhynchus prasinus) are changed because of a split from an extralimital species; (5) two species names are changed (to Circus hudsonius and Lanius borealis) because of splits from extralimital species; (6) one species (Larus thayeri) is lost by merger into a species already on the list; (7) six genera (Sibirionetta, Spatula, Mareca, Crithagra, Leistes, and Ptiloxena) are added as a result of splits from other genera, resulting in changes to 12 scientific names (Sibirionetta formosa, Spatula querquedula, S. discors, S. cyanoptera, S. clypeata, Mareca strepera, M. falcata, M. penelope, M. americana, Crithagra ...
