Sixty-fifth Supplement to the American Ornithological Society’s Check-list of North American Birds

Abstract

This is the 24th 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 25, 2023 and April 30, 2024 by the American Ornithological Society’s (formerly American Ornithologists’ Union) Committee on Classification and Nomenclature—North and Middle America. The Committee has continued to operate in the manner outlined in the 42nd Supplement (Banks et al. 2000). During the past year Oscar Johnson joined the committee, and J. V. Remsen, Jr. and Kevin Winker left the committee. Changes in this supplement include the following: (1) 1 species (Hippolais icterina) is added to the main list on the basis of new distributional information; (2) 16 species (Colinus leucopogon, Pterodroma caribbaea, Sula brewsteri, Ardea coromanda, Colaptes mexicanoides, Automolus cervinigularis, Campylorhynchus humilis, C. capistratus, Troglodytes musculus, T. beani, T. martinicensis, T. mesoleucus, T. musicus, T. grenadensis, Ramphocinclus sanctaeluciae, and Anthus japonicus) are added to the main list because of splits from species already on the list; (3) 1 species (Calonectris borealis) is added to the main list because of a split from a species already on the list, and the English name of that species (C. diomedea) is transferred to the new species; (4) 3 species names are changed (to Tyto furcata, Tolmomyias flavotectus, and Acrochordopus zeledoni) because of splits from extralimital species; (5) the English names and distributional statements of 4 species (Anarhynchus mongolus, Puffinus lherminieri, Ardea intermedia, and Tolmomyias flaviventris) are changed because of splits from extralimital species; (6) the distributional statements of 2 species (Gelochelidon nilotica and Oenanthe oenanthe) are changed, with no change in English name, because of splits from extralimital species; (7) 2 species (Acanthis cabaret and A. hornemanni) are lost by merger with a species already on the list; (8) 6 genera (Ortygornis, Eudromias, Anarhynchus, Hesperoburhinus, Acrochordopus, and Driophlox) are added due to splits from other genera, resulting in changes to 13 scientific names (Ortygornis pondicerianus, Eudromias morinellus, Anarhynchus mongolus, A. leschenaultii, A. veredus, A. wilsonia, A. collaris, A. montanus, A. nivosus, Hesperoburhinus bistriatus, Acrochordopus zeledoni, Driophlox fuscicauda, and D. atrimaxillaris) and the loss of 1 genus (Burhinus); (9) 4 genera (Ixobrychus, Bubulcus, Calocitta, and Psilorhinus) are lost by merger with genera already on the list, resulting in changes to 7 scientific names (Botaurus exilis, B. minutus, B. sinensis, Ardea ibis, Cyanocorax colliei, C. formosus, and C. morio); (10) the scientific name of 1 species is changed (to Chrysuronia boucardi) due to transfer between genera already on the list; (11) the hyphen is removed from the English group name of 3 species (Nycticorax nycticorax, Nyctanassa violacea, and Horornis diphone); (12) the English group name of one genus (Tolmomyias) is changed, resulting in changes to the English names of 3 species; and (13) 1 species (Circus aeruginosus) is added to the list of species known to occur in the United States.
