Males of both species still show a great deal of geographic variation, but this is considerably reduced compared to the previous single-species treatment.<\/p>\n\n\n\n<p><strong>Details: <\/strong>v2024 taxa 1030\u20131050, text: Polytypic Crested Bobwhite <em>Colinus cristatus<\/em> is split into polytypic Spot-bellied Bobwhite <em>Colinus leucopogon<\/em> (with subspecies <em>incanus, hypoleucus, leucopogon, leylandi, sclateri, <\/em>and<em> dickeyi<\/em>) and polytypic Crested Bobwhite <em>Colinus cristatus<\/em> (with subspecies <em>mariae, panamensis, decoratus, cristatus, littoralis, badius, leucotis, bogotensis, parvicristatus, horvathi, barnesi, mocquerysi, <\/em>and<em> sonnini<\/em>).<\/p>\n\n\n\n<p>Many taxa of <em>Colinus<\/em> from Guatemala through northern South America, which show a bewildering array of plumage variation among males, have long been treated as members of a single species, Crested Bobwhite <em>Colinus cristatus<\/em> (e.g., Hellmayr and Conover 1942, Sibley and Monroe 1990, NACC). Numerous other authors have however treated them as comprising two species, with the northern taxa treated as Spot-bellied Bobwhite <em>Colinus leucopogon<\/em> (e.g., Peters 1934, Wolters 1976, Blake 1977, Stiles and Skutch 1989, Carroll 1994, Madge and McGowan 2002, Dyer and Howell 2023). Indeed, earlier versions of Clements (at least through the 3<sup>rd<\/sup>) and Howard and Moore (through the 3<sup>rd<\/sup> edition) had adopted the two-species approach. <em>Colinus leucopogon<\/em> (Lesson, 1842) was originally described as a full species, as were three of its currently recognized subspecies (<em>hypoleucus, leylandi<\/em>, and <em>sclateri<\/em>). For <em>Colinus cristatus<\/em> (Linnaeus, 1766), six of its subspecies (<em>decoratus, leucotis, parvicristatus, horvathi, mocquerysi, <\/em>and<em> sonnini<\/em>) were described at the species level.<\/p>\n\n\n\n<p>The northern taxa of the <em>leucopogon<\/em> group, distributed from southern Guatemala through west-central Costa Rica, all lack a long crest but otherwise vary in males from having almost completely white underparts (in Guatemala and western El Salvador) through extensively and heavily spotted below on a brown or rufous background. In Honduras and western Nicaragua, males have black throats, while in northwestern Costa Rica males have white throats and rufous, white-spotted underparts. The southern taxa of the <em>cristatus<\/em> group, occurring from southwestern Costa Rica, have noticeably elongated crests but are otherwise similarly diverse as in the <em>leucopogon<\/em> group; while males of most taxa have rufous throats (unlike any taxa of the <em>leucopogon<\/em> group), others of the <em>cristatus<\/em> group have white or black throats. Notably, the taxa that approach each other most closely in Costa Rica are very strikingly different in numerous respects. As far as known these taxa (<em>dickeyi<\/em> of the <em>leucopogon<\/em> group in northwestern and west-central Costa Rica and <em>mariae<\/em> of the <em>cristatus<\/em> group in southwestern Costa Rica) are entirely allopatric, and <em>mariae<\/em> appears to be rare in Costa Rica (Dyer and Howell 2023).<\/p>\n\n\n\n<p>A recent genetic study utilizing samples from all subspecies of both groups (Salter et al. 2022) showed that the <em>leucopogon<\/em> and <em>cristatus<\/em> groups are monophyletic, though closely related. This monophyly of the groups demonstrates at least that the plumage features that define the groups are likely shared derived characters. Vocalizations are said to differ somewhat between the two groups (Stiles and Skutch 1989; Sandoval et al. in prep., cited in Sandoval 2020). It should, however, be noted that <em>Colinus<\/em> vocalizations are highly conserved, and that no published vocal analysis is yet available.<\/p>\n\n\n\n<p>The IOC-WBL checklist has treated the two groups as separate species since IOC-WBL v1.0. The SACC position on species limits is not explicitly stated (https:\/\/www.museum.lsu.edu\/~Remsen\/SACCBaseline.htm), and the <em>leucopogon<\/em> group is extralimital to the SACC region of coverage. In the HBW\/BLI checklist (del Hoyo and Collar 2014), the <em>leucopogon<\/em> group is treated as a separate species. The incongruence between IOC-WBL and HBW\/BLI vs. Clements checklists led to consideration by the AviList panel, which voted for the two-species treatment. NACC has long treated the <em>leucopogon<\/em> group as conspecific with the <em>cristatus<\/em> group, following Hellmayr and Conover 1942, but subsequent to the AviList decision, proposal 2024-C-18 to NACC by Chesser (2024), <a href=\"https:\/\/americanornithology.org\/wp-content\/uploads\/2024\/07\/2024-C-1-26-final.pdf\">https:\/\/americanornithology.org\/wp-content\/uploads\/2024\/07\/2024-C-1-26-final.pdf<\/a>, was accepted by NACC. Thus, the two-species AviList 1.0 treatment adopted here (Clements et al. 2024, van Dort and Sandoval 2024) aligns with IOC-WBL, BLI, and NACC (Chesser et al. 2024), among others.<\/p>\n\n\n\n<p><strong>English names<\/strong>: Continued use of the English name Crested Bobwhite for the <em>cristatus<\/em> group is maintained, as this group includes the conspicuously crested members, the name mirrors the specific epithet, and the range of the <em>cristatus<\/em> group now recognized as a species is considerably larger than that of the Spot-bellied Bobwhite. Continued usage of Spot-bellied Bobwhite for <em>Colinus leucopogon<\/em> is imperfect because members of certain taxa of both species may have spotted or unspotted bellies, and that the specific epithet, which means \u201cwhite beard\u201d also applies to members of both species (but mostly to <em>leucopogon<\/em>). However, the name Spot-bellied Bobwhite is adopted as it is deeply entrenched specifically with reference to <em>Colinus leucopogon<\/em>, is reasonably accurate and descriptive, and no obvious improvement is available.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Olive-capped Coua <em>Coua olivaceiceps<\/em><\/strong> is split from<strong> Red-capped Coua <em>Coua ruficeps<\/em><\/strong><strong><em><\/em><\/strong><\/h4>\n\n\n\n<p><strong>Summary:<\/strong> (1\u21922 species) Much remains to be learned about their interrelationships, but on present evidence southwestern Madagascar\u2019s Olive-capped Coua is better considered a separate species from Red-capped Coua of northwestern Madagascar. Field observers can improve knowledge by documenting any sightings in intervening areas of west-central Madagascar.<\/p>\n\n\n\n<p><strong>Details: <\/strong>v2024 taxa 3023\u20133024, text: Polytypic Red-capped Coua <em>Coua ruficeps<\/em> is split into monotypic Red-capped Coua <em>Coua ruficeps<\/em> and monotypic Olive-capped Coua <em>Coua olivaceiceps<\/em>.<\/p>\n\n\n\n<p>Despite the striking difference in crown coloration between the two coua taxa <em>Coua<\/em> <em>ruficeps <\/em>Gray, 1846 and <em>olivaceiceps <\/em>(Sharpe, 1873) that led Sharpe to describe the latter as a new species, their treatment has since been highly controversial, with some authors (e.g., Payne 2005, Erritz\u00f8e et al. 2012) citing a zone of introgression of unclear width as sufficient rationale for their conspecificity. In the case of del Hoyo and Collar (2014), a narrow zone of hybridization was considered to add to the evidence for separate species status. Conversely, other authors cited apparent sympatry between them as evidence of separate species status (Sinclair and Langrand 1998), while Benson et al. (1976) cited specimens of only one form from an area treated by others as being inhabited by both (Kirwan et al. 2024).<\/p>\n\n\n\n<p>Dowsett-Lemaire (2004) considered the vocalizations to differ strongly, based on a small number of recordings then available. The much larger sample now available online seems to confirm differences in pace and frequency of the rising song type, with <em>ruficeps<\/em> delivering a slower, lower-pitched version than that of <em>olivaceiceps<\/em> (see for example <em>ruficeps<\/em> xc 86881 vs. <em>olivaceiceps<\/em> xc 26573). Other vocalization types do not appear to differ strikingly. A vocal analysis will be required for confirmation of putative differences, and playback experiments may shed further light on species limits.<\/p>\n\n\n\n<p>Given the clear differences in plumage, apparent allopatry based on specimens (R. Dowsett in litt.) and examination of online photographs, and apparent song differences, <em>Coua olivaceiceps<\/em> is now treated by AviList as specifically distinct, and thus <em>Coua ruficeps<\/em> is now considered monotypic, under the assumption that the burden of proof should be on demonstrating conspecificity in the face of evidence to the contrary. The two-species AviList 1.0 treatment adopted here (Clements et al. 2024) aligns with IOC-WBL v14.2, and BLI v8.1, but not Peters (1940), Wolters (1976), Sibley and Monroe (1990), or Dickinson and Remsen (2013). Genetic comparisons of the two taxa are lacking, however, and further study of all aspects of their taxonomy is required.<\/p>\n\n\n\n<p><strong>English names<\/strong>: <em>Coua ruficeps<\/em>, whether referring to both taxa or to <em>ruficeps sensu stricto<\/em> has long been known as \u201cRed-capped Coua\u201d, although <em>Coua ruficeps<\/em> was called Olive-capped Coua by Sibley and Monroe (1990). Its range is only slightly larger than that of <em>Coua olivaceiceps<\/em>, and it may thus be argued that the name <em>ruficeps<\/em> now should be changed to avoid confusion with <em>olivaceiceps<\/em>. In addition, the cap is rufous or chestnut rather than true red, although this applies equally to other couas and indeed many other birds, and changing it in this case could lead to further disruption. Because the name \u201cRed-capped Coua\u201d is highly entrenched for <em>ruficeps<\/em>, and due to a lack of good alternatives, this name is maintained for the now-monotypic <em>Coua ruficeps<\/em>. <em>Coua olivaceiceps<\/em> has been known as \u201cOlive-capped Coua\u201d (del Hoyo and Collar 2014), \u201cBrown-capped Coua\u201d (Hawkins et al. 2015, where not split), and \u201cGreen-capped Coua\u201d (Sinclair and Langrand 2013; eBird Group). As the cap is not green, but brownish-olive, and \u201cOlive-capped\u201d mirrors the specific epithet, that name is adopted here.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Burchell&#8217;s Coucal <em>Centropus burchellii<\/em><\/strong> is split from <strong>White-browed Coucal <em>Centropus superciliosus<\/em><\/strong><\/h4>\n\n\n\n<p><strong>Summary:<\/strong> (1\u21922 species) The common coucal of savanna and disturbed habitats in eastern Africa, the White-browed Coucal and its black-crowned counterpart in southern Africa, the Burchell\u2019s Coucal, are now treated as separate species.<\/p>\n\n\n\n<p><strong>Details: <\/strong>v2024 taxa 3065\u20133072, text: Polytypic White-browed Coucal <em>Centropus superciliosus<\/em> is split into polytypic White-browed Coucal <em>Centropus superciliosus<\/em> (with subspecies <em>superciliosus<\/em> and <em>loandae<\/em>) and polytypic Burchell&#8217;s Coucal <em>Centropus burchellii<\/em> (with subspecies <em>fasciipygialis<\/em> and <em>burchellii<\/em>).<\/p>\n\n\n\n<p>Multiple African coucal species look similar to Burchell\u2019s, with solid black crowns and sides of face, while the White-browed Coucal <em>Centropus superciliosus<\/em> <em>sensu stricto<\/em>, when it does not include Burchell\u2019s Coucal, stands out due to the strikingly different head patterns in adults from the southwestern Arabian peninsula through eastern Africa (<em>superciliosus<\/em> group) compared to those of the southern third of Africa (<em>burchellii<\/em> group). They have long been considered conspecific, as there is a known area of hybridization (Dowsett and Dowsett-Lemaire 2006, Dowsett et al. 2008, Kirwan et al. 2024), but this is poorly studied. Adding to the confusion, young adults of <em>burchellii<\/em> apparently may breed in an immature plumage that appears similar to <em>superciliosus<\/em> or intergrades.<\/p>\n\n\n\n<p>Vocalizations are similar between the <em>superciliosus<\/em> and <em>burchellii<\/em> groups, but do not appear to have been comprehensively studied, nor has genetic evidence been brought to bear on the issue to our knowledge.<\/p>\n\n\n\n<p>Based on the high level of plumage differentiation between the two groups in this group of otherwise conservatively plumaged coucals over vast areas, with a seemingly narrow zone of hybridization, AviList 1.0 and thus Clements et al. (2024) recognize <em>Centropus burchellii<\/em> Swainson, 1838 (originally described as a full species, as was its subspecies <em>fasciipygialis<\/em>) as a separate species from <em>Centropus superciliosus <\/em>Hemprich and Ehrenberg, 1829. This aligns with Sibley and Monroe (1990) and IOC-WBL 14.2, but not BLI v8.1, Dickinson and Remsen (2013), Peters (1940), or Wolters (1976).<\/p>\n\n\n\n<p><strong>English names<\/strong>: The name Burchell\u2019s Coucal for <em>Centropus burchellii<\/em> has long been in use (e.g., Sibley and Monroe 1990). There is no obvious alternative for this species which has very similar plumage to other black-crowned African species (Senegal, Coppery-tailed, and Blue-headed), and it matches the specific epithet, so for the present at least this familiar name is retained.<\/p>\n\n\n\n<p>The name White-browed Coucal for <em>Centropus superciliosus<\/em> also has a very long history, is uniquely appropriate for the adult of this species, and also echoes the specific epithet. However, it has been extensively used for the combined species, and both have similar range sizes. Since it is such a familiar bird over a wide area, and the name is helpfully descriptive, White-browed Coucal is nevertheless retained.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Mentawai Malkoha <em>Phaenicophaeus oeneicaudus <\/em><\/strong>is split from <strong>Chestnut-breasted Malkoha <em>Phaenicophaeus curvirostris<\/em><\/strong><strong><em><\/em><\/strong><\/h4>\n\n\n\n<p><strong>Summary:<\/strong> (1\u21922 species) The distinctively plumaged Mentawai Malkoha adds yet another species to the list of endemics of this formerly underappreciated archipelago off western Sumatra.<\/p>\n\n\n\n<p><strong>Details: <\/strong>v2024 taxa 3125\u20133131, text: Polytypic Chestnut-breasted Malkoha <em>Phaenicophaeus curvirostris<\/em> is split into polytypic Chestnut-breasted Malkoha <em>Phaenicophaeus curvirostris<\/em> (with subspecies <em>singularis, curvirostris, deningeri, microrhinus, <\/em>and<em> harringtoni<\/em>) and monotypic Mentawai Malkoha <em>Phaenicophaeus oeneicaudus<\/em>.<\/p>\n\n\n\n<p>Of the six subspecies that have long been united under <em>Phaenicophaeus curvirostris <\/em>(Shaw, 1810), the form <em>oeneicaudus<\/em> Verreaux and Verreaux, 1855 endemic to the Mentawai Islands west of central Sumatra stands out on the basis of plumage coloration and was originally described at the species level, although it was not even granted group status by Sibley and Monroe (1990). The all-dark green (vs. largely chestnut) tail and underparts of <em>oeneicaudus<\/em> from the lower breast to the vent are the most obvious differences from all the other taxa, but <em>oeneicaudus<\/em> also differs in its iridescent green mantle, and from all except <em>harringtoni<\/em> of Palawan (also originally described as a full species, as was the Bornean subspecies <em>microrhinus<\/em>) by its extensively bare front of face. These differences led both del Hoyo and Collar (2014) and Eaton et al. (2016) to consider <em>oeneicaudus<\/em> a separate species.<\/p>\n\n\n\n<p>The Asian malkohas vocalize infrequently and indistinctly, and their vocalizations can even be mistaken for those of squirrels. The few recordings that do exist are not known to be helpful in determining species limits, although further documentation of their vocalizations, analyses, and playback experiments might possibly provide further informative data. To our knowledge, genetic data have not been brought to bear on this issue.<\/p>\n\n\n\n<p>Nevertheless, based on these plumage differences deemed more consistent with species than subspecies status, AviList and thus Clements (2024) confer full species status to <em>Phaenicophaeus oeneicaudus<\/em>. This AviList 1.0 treatment now aligns with BLI v8.1, IOC-WBL 14.2, and Eaton et al.

It should be noted that the Palawan form <em>harringtoni<\/em> also has several plumage differences from the others that suggest its species status should be reevaluated as well in future.<\/p>\n\n\n\n<p><strong>English names<\/strong>: The name Chestnut-breasted Malkoha is retained for <em>Phaenicophaeus curvirostris<\/em> with the split of <em>Phaenicophaeus oeneicaudus, <\/em>because the former is the parent species with a much broader distribution, it has long been used, and it is very widely familiar. The name Mentawai Malkoha for <em>Phaenicophaeus<\/em> <em>oeneicaudus<\/em> is highly appropriate and already somewhat familiar through its usage in the past decade by del Hoyo and Collar (2014) and Eaton et al.

The four-species circumscription does not align well with vocalizations (which are quite similar over a vast area) or biogeographical patterns. By far the most morphologically and vocally distinctive form is <em>crassirostris<\/em> (Salvadori, 1878, originally described as a full species) of Tanimbar and Kai islands, in the far eastern Indonesian archipelago, which is geographically surrounded by more typical members of the <em>minutillus<\/em> complex (of which five subspecies were originally described at the species level: <em>barnardi, misoriensis, poecilurus, russatus,<\/em> and <em>rufomerus<\/em>). Based on its phenotypic and vocal distinctiveness, <em>Chalcites crassirostris<\/em> is now treated as a full monotypic species by AviList 1.0 and Clements et al. 2024), aligning with Peters (1940), Sibley and Monroe (1990), Higgins (1999), Inskipp et al. (1996), King (1997), Dickinson and Remsen (2013), Eaton et al. (2021), IOC-WBL 14.2, and BLI v8.1, though not with Wolters (1976), Payne (2005), and several other sources. Based on mtDNA, however, <em>Chalcites crassirostris<\/em> is not strongly diverged from other taxa of the <em>minutillus<\/em> complex sampled (Sorensen and Payne 2005). <\/p>\n\n\n\n<p>The single Babar specimen ascribed to subspecies <em>salvadorii<\/em> has been considered closest to <em>crassirostris<\/em> in plumage and thus a subspecies of <em>crassirostris<\/em> when that is split (del Hoyo and Collar 2014), or alternatively a hybrid between <em>crassirostris<\/em> and <em>Chalcites minutillus rufomerus<\/em> (Ford 1982, Dickinson and Remsen 2013), but recent visual and aural observations on Babar suggest that <em>salvadorii<\/em> is a subspecies of <em>minutillus <\/em>(Eaton et al. 2016). Taxon <em>rufomerus<\/em> has also sometimes been treated as a subspecies of <em>crassirostris<\/em> but is similar vocally to other forms of <em>minutillus<\/em>, and is quite dissimilar in plumage to <em>crassirostris<\/em> (Eaton et al. 2016).

The small-range <em>Chalcites crassirostris<\/em> is widely known as Pied Bronze-Cuckoo (e.g., Sibley and Monroe 1990), and that name is reasonably appropriate although it suggests the species is black-and-white rather than iridescent green-and-white. Furthermore, two of the subspecies often treated therein (which are less or not at all pied in appearance) have been reassigned to <em>Chalcites minutillus<\/em>, and hence confusion is possible with the retention of this name.

A recent comprehensive paper (Wu et al. 2022a) elucidates vocal and morphological variation across the range of <em>Cacomantis variolosus<\/em> and shows that it is best treated as five species, and that <em>Cacomantis sepulcralis <\/em>(M\u00fcller, 1843) should retain separate species status. In addition, an undescribed taxon evidently occurs in the Tanimbar Islands (Wu et al. 2022a). The AviList 1.0 treatment of <em>Cacomantis variolosus<\/em> as comprising five species (Clements et al. 2024) now aligns with IOC-WBL 14.2, but not with Peters (1940), Wolters (1976), Sibley and Monroe (1990), Inskipp et al. (1996), King (1997), Dickinson and Remsen (2013) or BLI v8.1. A comprehensive genetic analysis of the <em>Cacomantis variolosus<\/em> complex is still lacking.<\/p>\n\n\n\n<p>In summary, the species now recognized are polytypic <em>Cacomantis sepulcralis<\/em> of southeast Asia through Philippines and the western Lesser Sundas (originally described as a full species); monotypic <em>Cacomantis<\/em> <em>virescens<\/em> (Br\u00fcggemann, 1876) of Sulawesi and associated islands; polytypic <em>Cacomantis variolosus<\/em> of the Moluccas and eastern Lesser Sundas through New Guinea and Australia to the Bismarck Archipelago; monotypic <em>Cacomantis blandus<\/em> Rothschild and Hartert, 1914 of the Solomon Islands; and monotypic <em>Cacomantis addendus<\/em> Rothschild and Hartert, 1901 of Manus in the Admiralty Islands, western Bismarck Archipelago. All these species-level taxa were originally described as species, as were three of the subspecies subsumed under <em>Cacomantis variolosus sensu stricto<\/em> (<em>tymbonomus, infaustus<\/em>, and<em> websteri<\/em>).<\/p>\n\n\n\n<p><strong>English names<\/strong>: The geographic names adopted for the daughter species of the <em>Cacomantis variolosus<\/em> complex agree with those proposed in Wu et al.

In Ecuador and far southern Colombia this species occurs in the Andes, while in Peru (where it is now extremely rare) it is primarily coastal, and a better alternative name that more accurately reflects habitat or range does not appear to be available.

While in Europe, only the European Herring Gull is expected and American is a vagrant, whereas the opposite is true for eastern North America. In eastern Asia both Vega and Mongolian winter widely, but Vega is more coastal and Mongolian more inland, especially in the breeding season.<\/p>\n\n\n\n<p><strong>Details: <\/strong>v2024 taxa 6472\u20136480, text: Polytypic Herring Gull <em>Larus argentatus<\/em> is split into polytypic European Herring Gull <em>Larus argentatus<\/em> (with subspecies <em>argenteus<\/em> and <em>argentatus<\/em>), monotypic American Herring Gull <em>Larus smithsonianus<\/em>, monotypic Vega Gull <em>Larus vegae<\/em>, and monotypic Mongolian Gull <em>Larus mongolicus<\/em>.<\/p>\n\n\n\n<p>The species limits of large white-headed gulls of the Holarctic are some of the most contentious among birds, with numerous studies attempting to elucidate these issues and varied treatments resulting from interpretation of these studies. Complicating factors in these decisions include the complexity of plumage sequences of four-year gulls, a strong propensity for interspecific hybridization, and the close similarity in plumage of adults in North America and Europe. For many years, the Herring Gull <em>Larus argentatus<\/em> has been treated by NACC and Clements et al. (through 2023) as polytypic and widespread in Europe, North America, and central to eastern Asia.<\/p>\n\n\n\n<p>However, there has been growing evidence that the European Herring Gull <em>Larus argentatus<\/em> Pontoppidan, 1763 and American Herring Gull <em>Larus smithsonianus<\/em> Coues, 1862 (originally described as a full species) are not each other\u2019s closest relatives, demonstrated by multiple genetic studies (Liebers et al. 2004; \u010cern\u00fd and Natale 2010; Sternkopf et al. 2010; Sonsthagen et al. 2016), following a much earlier analysis that found evidence for a lack of response by European birds to playback of calls of American birds (Frings et al. 1958). Vocal evidence from online recordings now confirms vocal differences between European and North American herring gulls, and it has long been known that their juvenile and first-winter plumages differ noticeably (e.g., Lonergan and Mullarney 2004). This, coupled with the genetic findings, has led AviList 1.0 and thus Clements (2024) to treat the two as separate species, <em>Larus smithsonianus<\/em> and <em>Larus argentatus<\/em>, aligning with IOC-WBL 14.2 and numerous other sources (e.g., Dyer and Howell 2023), but not with many other sources (e.g., Sibley and Monroe 1990, Beaman 1994, Inskipp et al. 1996, King et al. 1997). NACC will reconsider the issue in the near future.<\/p>\n\n\n\n<p>The Asian taxa <em>mongolicus<\/em> Sushkin, 1925 and <em>vegae<\/em> Palm\u00e9n,&nbsp;1887 (neither originally described as full species) have variously been considered part of the Herring Gull complex (Peters 1934), as conspecific with the American Herring Gull (Wolters 1975), Dickinson and Remsen (2013), or with each other (e.g., IOC-WBL since at least v3.1), among other treatments including conspecificity with Caspian Gull<em> Larus cachinnans<\/em>. However, they differ phenotypically in several ways both as adults and immatures, they occupy essentially different habitats throughout the year, and they likely do not overlap in the breeding season. Genetic analyses do not uphold a particularly close relationship between these two. Vocally they are quite different, with <em>vegae<\/em> being most similar to both European and American Herring Gulls, while the voice of <em>mongolicus<\/em> differs strongly from all these, being more similar to but still different from, <em>Larus cachinnans<\/em> (Weseloh et al. 2024). Thus, it is concluded that each is best treated as a full species, <em>Larus vegae<\/em> and <em>Larus mongolicus <\/em>(Clements et al. 2024, AviList 1.0).<\/p>\n\n\n\n<p><strong>English names<\/strong>: The English name Vega Gull has been used both for <em>Larus vegae<\/em> when it includes <em>mongolicus<\/em> and when it is considered monotypic, but it is strongly entrenched as such and thus, in the absence of a preferred alternative, is retained. The name Mongolian Gull for <em>Larus mongolicus<\/em> is unambiguous and appropriate, though the species vacates Mongolia for the non-breeding season. Because the name \u201cHerring\u201d is so entrenched for both North American and European species, the names European Herring Gull for <em>Larus argentatus sensu stricto<\/em> and American Herring Gull <em>Larus smithsonianus<\/em> are adopted in preference to e.g., Herring Gull for <em>Larus argentatus sensu stricto <\/em>and Smithsonian Gull <em>Larus smithsonianus<\/em>, adopted in some sources.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Cory\u2019s Shearwater <em>Calonectris borealis<\/em><\/strong> and <strong>Scopoli\u2019s Shearwater<em> Calonectris diomedea<\/em><\/strong> are split from Cory\u2019s Shearwater <em>Calonectris diomedea<\/em><\/h4>\n\n\n\n<p><strong>Summary:<\/strong> (1\u21922 species) With the split of Cory\u2019s Shearwater, observers on pelagic trips in the Atlantic will need to carefully photo-document their sightings to distinguish the Mediterranean-breeding Scopoli\u2019s from the northeastern Atlantic-breeding Cory\u2019s.<\/p>\n\n\n\n<p><strong>Details:<\/strong> v2024 taxa 7119\u20137120, text: Polytypic Cory\u2019s Shearwater <em>Calonectris diomedea<\/em> is split into monotypic Cory\u2019s Shearwater <em>Calonectris borealis<\/em> and monotypic Scopoli\u2019s Shearwater <em>Calonectris diomedea<\/em>.<\/p>\n\n\n\n<p>While being very similar in appearance, the two subspecies long united under <em>Calonectris diomedea<\/em><a>\u2014<\/a><em>borealis<\/em> (Cory, 1881) which breeds on islands in the northeastern Atlantic, and <em>diomedea<\/em> (Scopoli,&nbsp;1769) which breeds on islands in the Mediterranean, with a third closely related taxon <em>Calonectris edwardsii<\/em> (Oustalet, 1883) breeding in Cape Verde Islands\u2014have been extensively studied for many aspects of their biology (del Hoyo et al. 2024).

In addition, the <em>brewsteri<\/em> group is most divergent mitochondrially from the others (Morris-Pocock et al. 2011), commensurate with species-level in some other taxa (Mlodinow et al. 2024). It should be noted that subspecies <em>etesiaca<\/em> Thayer and Bangs, 1905 of the <em>brewsteri<\/em> group does not typically have such prominently white-headed males as in <em>brewsteri<\/em>.

Several genetic studies (e.g., Aliabadian et al. 2016, Uva et al. 2018) have shown deep divergence between three major clades, a North American one and two Old World clades, each with several subspecies including morphologically distinct insular forms. Nevertheless, too many unsampled clades and other unanswered questions have remained to allow confident reassessment of species limits.<\/p>\n\n\n\n<p>Recently, close attention has been paid to vocalizations, some of which are confusingly similar and variable, but one vocalization type is evidently limited to New World populations (Robb et al. 2015). This strongly supports the non-conspecificity of the American <em>furcata<\/em> clade with the Old World clades. However, the two major Old World clades, <em>alba<\/em> and <em>javanica<\/em>, are non-sister in multiple analyses, with the <em>furcata<\/em> and <em>alba<\/em> clades instead being sister. One of many additional aspects complicating the picture is the fact that the Ashy-faced Owl <em>Tyto<\/em> <em>glaucops<\/em> (Kaup,&nbsp;1853) of Hispaniola is closely related to <em>Tyto alba<\/em> but cannot be conspecific, as the two coexist in sympatry.

Now, a genomic dataset (McCullough et al. 2022) has provided further evidence on relationships, but sampling is still far from complete. Furthermore, only limited vocal comparisons have been published (Boesman 2016: #180) and few if any recordings exist for many taxa, those that do exist amply demonstrate that the vocalizations of several forms differ dramatically, in at least one case within what is currently considered a single subspecies, <em>Edolisoma tenuirostre saturatius<\/em> Rothschild and Hartert, 1902, from several of the Solomon Islands (and this taxon also appears in two different clades in the mtDNA phylogeny).<\/p>\n\n\n\n<p>Reconciliation of the mtDNA phylogeny with morphology and what can be gleaned from available vocalizations has resulted in the novel set of taxonomic changes detailed here (Clements et al. 2024, AviList 1.0, del Hoyo et al. 2024).

Some more recent sources, including up through Clements 6<sup>th<\/sup> edition and IOC-WBL v.4.3, had treated them as two species, <em>Pachycephala vitiensis<\/em> Gray, 1860 for the white-throated forms and <em>Pachycephala graeffii<\/em> Hartlaub, 1866 for the yellow-throated forms, which vary greatly in other respects, with some evidence of intergradation (Mayr 1932 a, b).<\/p>\n\n\n\n<p>When genetic data (J\u00f8nsson et al. 2014, Andersen et al. 2014, and now Brady et al. 2022) became available it was shown that the <em>vitiensis<\/em> complex (including the forms under <em>graeffii<\/em>) is monophyletic, and that the Temotu (Santa Cruz, far southeastern Solomon Islands) forms were closely related, which led to multiple iterations of change in the species limits of the complex, most recently to treatment of all Fiji forms as a single species. While this can be justified on the basis of genetic phylogenies, these also show that clearly there are other forms (e.g., <em>torquata<\/em> Layard, 1875 of Taveuni and <em>kandavensis<\/em> of Kadavu Ramsay, 1876) that are genetically somewhat distinct as well and that there is not a simple genetic dichotomy between white-throated birds of the <em>vitiensis<\/em> group and yellow-throated birds of the <em>graeffii<\/em> group; this has been considered part of the rationale between the single-species treatment for Fiji taxa.<\/p>\n\n\n\n<p>Further evidence can be drawn from vocalizations, however. These differ to a moderate degree between the yellow-throated forms on the main islands of Viti Levu, Vanua Levu, and especially Taveuni, but are strikingly different, to the point of being unrecognizable, on the outlying island of Kadavu, where the whiplash (usually terminal) note type is lacking or minimal in song of <em>kandavensis<\/em>. While song is unavailable for nominate <em>vitiensis<\/em> from the relatively remote Gau (Ngau), <em>kandavensis<\/em> can hardly be conspecific with the <em>graeffii<\/em> group, and that a return to the prior two-species treatment for Fiji birds is justified, in the knowledge that further species-level splits (e.g., <em>kandavensis<\/em> from <em>vitiensis<\/em> and <em>torquata<\/em> of Taveuni from the <em>graeffii<\/em> group) are much more likely and better justified than a return to a single-species treatment for all Fiji subspecies. As mentioned, this AviList 1.0 treatment (Clements et al. 2024) is not novel, and its return now aligns with IOC-WBL 14.2, but not with older checklists including Paynter (1967), Wolters (1980), Sibley and Monroe (1990), Dickinson and Christidis (2014), or BLI v8.1. Not surprisingly, several forms in this complex were originally described as full species in the 19<sup>th<\/sup> century: the two considered full species here, as well as <em>kandavensis<\/em> and <em>torquata<\/em> (which are likely split candidates), <em>optata<\/em> Hartlaub, 1866, and the vocally distinctive <em>aurantiiventris<\/em> Seebohm, 1891 of Vanua Levu. However, on the main islands of Viti Levu and Vanua Levu variation between extremes is complex, with numerous reported intergrades (Seebohm 1891, Mayr 1932a, b), so plumage is clearly not isolating these taxa.<\/p>\n\n\n\n<p><strong>English names<\/strong>: Given the complexity of the \u201cGolden Whistler <em>Pachycephala pectoralis<\/em> <em>sensu lato<\/em>\u201d complex, we consider that the situation is best served by the compound names White-throated Fiji Whistler for <em>Pachycephala vitiensis<\/em> and Yellow-throated Fiji Whistlerfor<em> Pachycephala graeffii<\/em>.

The variation they exhibit led del Hoyo and Collar (2016) to place them in five different groups within the same species, and based partly on vocalizations, Eaton et al.

However, the HBW\/BLI checklist used the group name \u201cKikuyu Mountain Greenbul\u201d, which fits well with the specific epithet and part of the range of the species, although the species also occurs in the Albertine Rift.

The IOC-WBL (through v.14.1) name \u201cMountain Greenbul\u201d is problematic too because it has been extensively used for the group name. The HBW\/BLI checklist uses \u201cKilimanjaro Mountain Greenbul\u201d for the <em>nigriceps<\/em> group and \u201cUsambara Mountain Greenbul\u201d for the <em>usambarae<\/em> group.

This treatment was followed in Kirwan et al.

Among many other aspects of the case built in this proposal was the radically different songs of several of the taxa, especially the St. Vincent form <em>musicus<\/em> (Lawrence, 1878), as well as ecological differences including the dry forest habitat of St. Lucia\u2019s <em>mesoleucus<\/em> (Sclater, 1876) (Kirwan et al. 2019). Nevertheless, the proposal did not pass largely due to uncertainty about species limits within Caribbean taxa rather than recognition that change was needed. Subsequently, a comprehensive genetic analysis (Klicka et al. 2023) better elucidated the relationships between taxa, and was used as the partial basis for a revised proposal (Rasmussen et al. 2022, <a href=\"https:\/\/americanornithology.org\/wp-content\/uploads\/2024\/07\/2024-C-1-26-final.pdf\">https:\/\/americanornithology.org\/wp-content\/uploads\/2024\/07\/2024-C-1-26-final.pdf<\/a>) that proposed a somewhat different seven-way split. Klicka et al. (2023) showed a deep divergence between northern and southern clades, and that the Caribbean taxa are embedded in various positions within the southern clade, despite their divergent morphology, vocalizations, and ecology (Johnson and Ju\u00e1rez 2024).<\/p>\n\n\n\n<p>Some of the species proposed are thus paraphyletic, but given the degree of morphological, vocal, and ecological divergence, they are best treated at the species level, and this proposal was accepted by NACC and WGAC.

Several of the plumage types are repeated on widely separated islands, as well as being closely similar to those of different species on continents and even different hemispheres. Not only that, but neighboring taxa may differ greatly in plumage, as on mountain ranges in Mindanao. And, one plumage type\u2014the bright rufous-headed <em>ruficeps<\/em> (Ramsay,&nbsp;1875)\u2014is unique within the genus <em>Turdus<\/em> and occurs only in mountains of a single small island, Kadavu, in Fiji, while that archipelago has no fewer than five very distinct plumage types. Efforts to redefine species limits in a manner that would lead to a set of species more in keeping with those of continental species of <em>Turdus<\/em> on the basis of plumage and size (Peterson 2007) met with limited success and a lack of uptake by global checklists. Sibley and Monroe (1990) divided the complex into just three groups: the widespread <em>poliocephalus<\/em> Latham, 1801, New Guinea <em>papuensis <\/em>(de Vis, 1890), and New Caledonia <em>xanthopus<\/em> Forster, 1844 groups. Even in the large-scale revision of global avian species limits conducted by del Hoyo and Collar (2016), no changes were made to this complex, and they stated that \u201cthere continues to be no better solution to this long-standing source of taxonomic discomfort than to leave the species as the most diverse assemblage of subspecies of bird known on earth.\u201d<\/p>\n\n\n\n<p>Phylogenetic analyses with limited sampling of taxa in the <em>Turdus poliocephalus<\/em> complex resulted in the finding that the Taiwan form <em>niveiceps<\/em> was not part of the assemblage, while the other forms sampled form a closely related, monophyletic group (Jones and Kennedy 2008; Nylander et al. 2008). With nearly comprehensive sampling and genomic data, Reeve et al. (2023) presented a phylogenetic analysis that finally enabled the long-needed revision to species limits of the <em>Turdus poliocephalus<\/em> complex. While it is now clear that this is a monophyletic and young assemblage of taxa, the diversity of vocal types, although not yet comprehensive nor formally analyzed, belie any notion that they should all be treated as conspecific. For example, although it is relatively well-studied, the Samoan form <em>samoensis<\/em> Tristram, 1879 is not known to sing, very unlike its nearest relatives (both geographically and phylogenetically) in Fiji. In addition, the Christmas Island form <em>erythropleurus<\/em> Sharpe,&nbsp;1887 (for example) is tame, approachable, and catholic in lowland habitat (Menkhorst et al. 2017), while several other forms are skulking, shy, and restricted to montane forest (Dutson 2011).<\/p>\n\n\n\n<p>With Reeve et al. (2023) giving the needed backbone to the major clades, a conservative first pass revision was made for AviList 1.0 in defining 17 species in the complex, as follows (Clements et al. 2024):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><em>Turdus mindorensis<\/em> Ogilvie-Grant, 1896 of Mindoro, west-central Philippines.

Further inspection of recordings now available seems to confirm the vocal differences. The two-species AviList 1.0 treatment adopted here (Clements et al. 2024) is shared with BLI v8.1 and IOC-WBL since v.12.1, but does not align with the older works of Paynter (1967), Wolters (1979), Sibley and Monroe (1990), or Dickinson and Christidis (2014). Of all five taxa recognized by Clements et al.

Although very similar in breeding plumage, <em>japonicus<\/em> Temminck and Schlegel, 1847 and the <em>rubescens<\/em> Todd, 1935 complex (including <em>alticola<\/em> Todd, 1935) differ markedly in non-breeding plumage and usually in soft part colors; there are differences in some call notes that are on par with species-level status among this group of pipits, and the genetic distance between <em>japonicus<\/em> and <em>rubescens<\/em>, though modest, is greater than in some other species pairs in this group (Lee and Birch 2002, Doniol-Valcroze et al. 2023). A proposal to NACC (Rasmussen et al. 2024) passed, as it did when voted on by WGAC. This AviList 1.0 treatment (Clements et al. 2024) now matches the taxonomy in Chesser et al. 2024 and IOC-WBL 14.2, but not most earlier treatments including Mayr and Greenway (1960), Wolters (1979), Sibley and Monroe (1990), Beaman (1994), Inskipp et al. (1996), King (1997), BLI v8.1, and Dickinson and Christidis (2014). Of the four taxa recognized as subspecies in Clements v2023, only <em>rubescens<\/em> was originally described as specifically distinct. The potential contact zone between the <em>rubescens<\/em> group and <em>japonicus<\/em> remains unstudied, however, and further study is needed.<\/p>\n\n\n\n<p><strong>English names<\/strong>: The highly familiar name American Pipit, which was never widely adopted in the Old World (e.g., Beaman 1994, Inskipp et al. 1996, King 1997, Shirihai and Svensson 2018), is retained for <em>Anthus<\/em> <em>rubescens<\/em> <em>sensu stricto<\/em>, while the name Siberian Pipit (used in several sources, including Lee and Birch 2002) is adopted for <em>Anthus<\/em> <em>japonicus<\/em> in preference to the name Japanese Pipit, given that it has a broad breeding range in eastern Russia. This aligns with NACC (Chesser et al. 2024). Since Buff-bellied Pipit has been used in western Europe (for primarily <em>rubescens<\/em>) and in South Asia (for primarily <em>japonicus<\/em>), it seems best to retire that name as it clearly has been used for the sensu lato concept, not for either taxon <em>sensu stricto<\/em><strong>.<\/strong><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Stripe-breasted Seedeater <em>Crithagra striatipectus<\/em><\/strong> is split from <strong>Reichard\u2019s Seedeater <em>Crithagra reichardi<\/em><\/strong><\/h4>\n\n\n\n<p><strong>Summary:<\/strong> (1\u21922 species) The split of Stripe-breasted Seedeater of northeast Africa from Reichard\u2019s Seedeater of southeast Africa should cause little confusion, as these species occur in very different habitats and are already known by these names in some field guides.<\/p>\n\n\n\n<p><strong>Details: <\/strong>v2024 taxa 32177\u201332178, text: Polytypic Reichard\u2019s Seedeater <em>Crithagra reichardi<\/em> is split into monotypic Stripe-breasted Seedeater <em>Crithagra striatipectus<\/em> and monotypic Reichard\u2019s Seedeater <em>Crithagra reichardi<\/em>.<\/p>\n\n\n\n<p>Several taxa of mostly brown, streaky seedeaters in Africa have been the subject of greatly differing treatments, for example Paynter (1968) recognized 10 subspecies in <em>Serinus gularis<\/em>, including <em>striatipectus<\/em> (Sharpe,&nbsp;1891) of northeast African and <em>reichardi <\/em>(Reichenow, 1882) of southeast Africa.

Given a similar level of divergence between several other taxa in this group, the two-species AviList 1.0 approach is adopted (Clements et al. 2024), and now aligns with Dickinson and Christidis (2014), BLI v8.1, and IOC-WBL since v11.2, but not earlier treatments including Paynter (1968), Wolters (1979), and Sibley and Monroe (1990).

Many errors easily slip through the cracks, so we greatly appreciate you letting us know of any that you find. If you can send a supporting reference or citation when reporting a potential change, that\u2019s even more helpful. Thanks for whatever you can do!<\/p>\n\n\n\n<p>Special thanks go to our many collaborators who carefully reviewed advance versions of this checklist, though of course any remaining errors are our responsibility. Max Kirsch deserves special thanks for his incredibly detailed review of our entire file, catching many hard-to-find errors in the process. We especially acknowledge Terry Chesser, for providing advance copies of work in progress, and to both Terry and to Van Remsen for their underappreciated roles in chairing regional classification committees (NACC and SACC, respectively). Special thanks also go to the hard-working members of NACC and SACC, who wrote and reviewed extra proposals in alignment with the WGAC process. David Donsker, Managing Editor of the <a href=\"https:\/\/www.worldbirdnames.org\/new\/\">IOC World Bird List<\/a>, has played a huge role in alignment of the Clements and IOC lists, as well as on WGAC. And we are beyond grateful to members of IOU\u2019s WGAC (Working Group Avian Checklist) for scientific input and discussions, specifically Juan Ignacio (Nacho) Areta, Paul Donald, Robert Dowsett, Frank Rheindt, and Richard Schodde who join Rasmussen, Schulenberg, Donsker, and Chesser in the Taxonomic group, Santiago Claramunt and Alan Peterson join Donald, Dowsett, Rasmussen, and Rheindt on the nomenclatural group (Working Group Avian Nomenclature or WGAN) and Donsker leads the WGAC bibliographic group. Most of our species-level updates this year have specifically aligned with WGAC decisions and we are excited about the collegiality and the process and look forward to the publication of the WGAC list in the coming year.<\/p>\n\n\n\n<p>We also thank the following for their help in providing helpful comments on the eBird\/Clements Checklist and related issues:<\/p>\n\n\n\n<p>Mark Adams, Roger Ahlman, Margaret and Richard Alcorn, Desmond Allen, Gary Allport, Per Alstr\u00f6m, Mike Andersen, Natalya Andreyenkova, Nick Anich, Juan Ignacio (Nacho) Areta, Christian Artuso, Gregory Askew, Nick Athanas, Gustave Axelson, Louis Backstrom, Stephen F.
