Sixty-second Supplement to the American Ornithological Society’sCheck-list of North American Birds

This is the 21st 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 15 April 2020 and 15 April 2021 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, Blanca E. Hernández-Baños was added to the committee. Changes in this supplement include the following: (1) 4 species (Columba palumbus, Amazilis amazilia, Ichthyaetus ichthyaetus, and Helopsaltes certhiola) are added to the main list on the basis of new distributional information; (2) 6 species (Larus brachyrhynchus, Strix sartorii, Sitta insularis, Euphonia godmani, Basileuterus delattrii, and Melopyrrha grandis) are added to the main list because of splits from species already on the list; (3) 1 species (Cistothorus stellaris) 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. platensis) is transferred to C. stellaris; (4) 1 species name is changed (to Polioptila bilineata) because of a split from an extralimital species; (5) 1 species name is changed (to Caracara plancus) because of a lump with an extralimital species, but with no change to the English name; (6) the English name and distributional statement of 1 species (Catharus dryas) are changed because of a split from an extralimital species; (7) the distributional statements of 5 species (Hydrobates castro, Thamnistes anabatinus, Ramphocaenus melanurus, Anthus lutescens, and Turdus merula) are changed because of splits from extralimital species; (8) the distributional statement of 1 species (Oxyura jamaicensis) is changed because of a lump with an extralimital species; (9) 6 genera (Urile, Nannopterum Corthylio, Padda, Glaucestrilda, and Amphispizopsis) are added due to splits from other genera, resulting in changes to 9 scientific names (Urile penicillatus, U. urile, U. pelagicus, Nannopterum auritum, N. brasilianum, Corthylio calendula, Padda oryzivora, Glaucestrilda caerulescens, and Amphispizopsis quinquestriata); (10) 2 genera (Canachites and Philodice) are added due to splits from other genera, resulting in the loss of those genera (Falcipennis and Calliphlox, respectively) and changes to 3 scientific names (Canachites canadensis, Philodice bryantae, and P. mitchellii); (11) 1 genus (Ramphotrigon) is added because of a lump with another genus, resulting in the loss of that genus (Deltarhynchus) and a change to 1 scientific name (Ramphotrigon flammulatum); (12) 1 genus (Pseudoscops) is lost by merger with a genus already on the list, resulting in changes to two scientific names (Asio clamator and A. grammicus); (13) the scientific names of 2 species are changed (to Chlorophonia elegantissima and C. musica) due to transfer between genera already on the list; (14) the hyphen is removed from the English name of 1 species (Helopsaltes ochotensis); (15) 1 species (Nesoctites micromegas) is transferred between subfamilies already on the list; (16) the type locality of 1 species (Colinus nigrogularis) is changed; (17) 1 species (Forpus spengeli) is added to the Appendix, replacing another species (F. xanthopterygius); and (18) 1 species (Lonchura malacca) is added to the list of species known to occur in the United States. New linear sequences are adopted for families in the order Passeriformes, for genera and species in the families Regulidae, Polioptilidae, and Estrildidae, for species in the genus Chaetura, and for species in the subfamily Euphoniinae, all due to new phylogenetic data. Literature that provides the basis for the Committee’s decisions is cited at the end of this supplement, and citations not already in the Literature Cited of the 7th edition (with supplements) become additions to it. A list of the bird species known from the AOS Check-list area can be found at http://checklist.americanornithology.org/taxa, and proposals that form the basis for this supplement can be found at https://americanornithology.org/nacc/current-prior-proposals/2021-proposals/.
