Go directly to 2022 Updates & Corrections<\/a><\/p>\n\n\n\n This is the 16th installment of taxonomic revisions and updates following the publication, in 2007, of the 6th edition of The Clements Checklist of Birds of the World<\/em>. Because the Clements Checklist has become tightly interwoven with eBird<\/a>, the checklist now is referred to as the eBird\/Clements Checklist<\/strong>. The entire checklist (including documentation of all revisions) is available as a downloadable spreadsheet <\/a>(in Excel and .csv formats). This year\u2019s spreadsheet version is eBird\/Clements Checklist v2022, and was released on 25 October 2022.<\/p>\n\n\n\n As usual, we post a list of the major 2022 Updates & Corrections (e.g., new species, splits, lumps, and name changes) here. As noted above, however, full documentation of all changes is incorporated into the spreadsheet itself; and eBird also has a very useful summary of the major changes<\/a>.<\/p>\n\n\n\n The spreadsheet contains 15 fields (data columns):<\/p>\n\n\n\n sort v2022<\/strong> \u2013 Reflects the sequence of species, groups, and subspecies in eBird\/Clements v2022<\/p>\n\n\n\n Clements v2022 change<\/strong> \u2013 A brief note to signal that a change from eBird\/Clements Checklist v2021 occurred for that entry. Sometimes only a single change is made per entry; in other cases several changes are made.<\/p>\n\n\n\n text for website v2022<\/strong> \u2013 Provides a fuller explanation of the change(s) from Clements Checklist v2021 that occurred for that entry.<\/p>\n\n\n\n category<\/strong> \u2013 Reflecting whether the entry on that line is a species; a subspecies; a monotypic group (i.e., a group that is equivalent to a single subspecies); or a polytypic group (a group composed of two or more subspecies). Thus, the total number of subspecies recognized in the eBird\/Clements Checklist is the sum of all entries listed as “subspecies” and as “group (monotypic)”.<\/p>\n\n\n\n English name<\/strong><\/p>\n\n\n\n scientific name<\/strong><\/p>\n\n\n\n authority<\/strong> \u2013 The name(s) of the person, or group of people, who described a species or subspecies, followed by the year of publication of the description (this feature is added in 2022)<\/p>\n\n\n\n name and authority<\/strong> \u2013 The full scientific name combined with the authority, in a single column (this feature is added in 2022)<\/p>\n\n\n\n range<\/strong><\/p>\n\n\n\n order<\/strong><\/p>\n\n\n\n family<\/strong><\/p>\n\n\n\n extinct<\/strong> \u2013 an entry (1) in this column means that the species or subspecies is extinct<\/p>\n\n\n\n extinct year<\/strong> \u2013 Reflects the year the species or subspecies went extinct (or, since the extinction date rarely is known with certainty, an approximation of the last year in which it was reported); \u201cxxxx\u201d is used when the date of extinction is not readily accessible.<\/p>\n\n\n\n sort v2021<\/strong> \u2013 Reflecting the sequence of species in eBird\/Clements Checklist v2021<\/p>\n\n\n\n page 6.0<\/strong> \u2013 Reflecting the page number of the species in the last (sixth) print edition (2007)<\/p>\n\n\n\n In this year’s updates, we add “only” three newly described species, which come from two different regions. Two of these new species are from the Meratus Mountains in southeastern Borneo: Meratus White-eye Zosterops meratusensis<\/em> and Meratus Blue Flycatcher Cyornis kadayangensis<\/em>. The third new species also represents a newly described genus: Inti Tanager Heliothraupis oneilli<\/em> of southern Peru and northern Bolivia. Two other additions are species that had been described long ago, but each had been confused with a different, more familiar species until recent field work confirmed their validity as separate species: New Caledonian Storm-Petrel Fregetta lineata<\/em>, of the southwestern Pacific Ocean, and Ruvu Weaver Ploceus holoxanthus<\/em> of eastern Tanzania.<\/p>\n\n\n\n Otherwise this year’s checklist includes 118 splits and 41 lumps; including the five new species listed above, this amounts to a net gain of 82 species. In terms of splits and lumps, we are current with the 2022 decisions of the American Ornithological Society’s North American Classification and Nomenclature Committee (NACC)<\/a>, and the decisions of the AOS’s South American Classification Committee<\/a> (SACC) through July 2022. Additionally, the eBird\/Clements Checklist is a participant in the Working Group Avian Checklists<\/a> (WGAC), a collaborative effort at reaching consensus and alignment on avian classification, under the auspices of the International Ornithologist’ Union. Currently WGAC is focused on alignment at the level of the species and genus. In the future, after WGAC completes the first sweep across all species-related cases, consensus will be sought at higher and lower levels of classification; and of course WGAC will have plenty to do going forward to stay current with new research findings. We have implemented most WGAC decisions through June 2022.<\/p>\n\n\n\nSummary Statistics for eBird\/Clements Checklist v2022<\/h2>\n\n\n\n
