Subspecies Updates IOC Version 13.2

Species	Previous Versions	Proposed Change	Code	Notes & Sources
White-tipped Dove	Leptotila verreauxi chalcauchenia	Leptotila verreauxi chlorauchenia	TAX	Formerly Leptotila verreauxi chalcauchenia Sclater, PL & Salvin, 1870, but L. v. chlorauchenia Giglioli & Salvadori, 1870 has precedence (Dickinson & Aimassi 2022).
White-breasted Waterhen	Amaurornis phoenicurus	Add subspecies leucocephalus.	ADD	Recognize following Praveen & Khot (2023).
American Barn Owl	Tyto furcata nigrescens; Tyto furcata insularis	Tyto glaucops nigrescens, Tyto glaucops insularis	TAX	In the absence of vocal and genetic data to the contrary, tentatively reassign ssp. nigrescens and insularis, dark-plumaged forms, from pale-plumaged T. furcata to dark-plumaged Ashy-faced Owl T. glaucops (del Hoyo & Collar 2014; HBW/BirdLife).
Yellow-spotted Barbet	Buccanodon duchaillui	Add newly described, vocally distinct taxon dowsetti as a subspecies.	TAX	Morphologically 'identical' western populations were initially proposed (10.1) to be recognized as Buccanodon dowsetti sp. nov. (Boesman & Collar, 2019) based on very different vocalizations from B. duchaillui (first noted by Borrow & Demey 2001). Replaces B. duchaillui west of the Dahomey Gap. A recent mtDNA analysis for genetic divergence found a genetic break at the Dahomey Gap, but also identified deep divergence among other populations in the eastern part of the species’ range (Hall et al. 2021). The taxonomic consequences of this finding is unresolved, but it is strongly suggestive of greater cryptic diversity within the Buccanodon duchaillui complex than expected. Tentatively treat the newly described taxon dowsetti as a subspecies for now, pending more comprehensive study.
Ochraceous Piculet	Picumnus limae	Restore subspecies fulvescens and the nominate subspecies.	TAX	Tawny Piculet Picumnus fulvescens was lumped with Ochraceous Piculet Picumnus limae as a monotypic species based on clinal plumage variation (Lima et al. 2020; SACC 845). In so doing fulvescens was treated as a junior synonym of limae following SACC 845. But Ochraceous Piculet is strongly differentiated at the geographic extremes of its range. This is best recognized by treating fulvescens as a valid subspecies.
Rüppell's Parrot	Poicephalus rueppellii	Add newly described subspecies mariettae and the nominate subspecies.	NEW	Subsp. nov.: Hubers & Schnitker, 2022. Newly recognized subspecies based on morphological differences from the nominate subspecies (Hubers et al. 2023)..
Plain Xenops	Xenops minutus	Add subspecies alagoanus.	ADD	Recognize alagoanus as a distinct subspecies (Dickinson & Christidis 2014; del Hoyo & Collar 2016; contra Remsen 2003). If split of Xenops genibarbis is recognized, alagoanus would be assigned to that species, not synonymize with to X. m. minutus as in Remsen (2003).
Western Olivaceous Flatbill	Rhynchocyclus aequinoctialis	Add subspecies cryptus.	ADD	Subsp. nov. : Described as a full species based on vocalizations and phylogenetics (Simões et al. 2021).

Black-and-white Becard	Pachyramphus albogriseus	Move subspecies guayaquilensis to split Cryptic Becard Pachyramphus salvini as a junior synonym. Delete subspecies coronatus.	DEL, TAX	Move subspecies guayaquilensis to split Cryptic Becard Pachyramphus salvini as a junior synonym. Treat subspecies coronatus as a junior synonym of the nominate subspecies of Black-and-white Becard.

Sand Lark	Alaudala raytal	Delete subspecies krishnakumarsinhji.	DEL	Subspecies krishnakumarsinhji is regarded as a synonym of A. r. adamsi as a locally adapted color morph (Ganpule & Alström 2023).
Pacific Robin	Petroica pusilla	Add recently described subspecies tannensis.	ADD	subsp. nov.: Kearns & Omland, 2015. Formerly included in P. p. similis but split by differences in plumage, bill size and genetics (Kearns et al. 2015).
Black-headed Tailorbird	Orthotomus nigriceps	Add recently described subspecies luminosus and the nominate subspecies.	ADD	subsp. nov.: Halley, 2022.
Large Ground Finch	Geospiza magnirostris	Add subspecies darwini and the nominate subspecies.	ADD	The variable subspecies darwini was formerly listed as a probable hybrid taxon in the comment under Geospiza conirostris based on some individuals resembling that species and others more similar to G. magnirostis (Grant 1986). Recently tentatively treated as a subspecies of the latter based on the curvature of the sides of the beak which closely resembles that of G. magnirostris (Grant 1986). This treatment is followed by del Hoyo & Collar (2016) and HBW/BirdLife.

Fiery-necked Nightjar	Caprimulgus pectoralis	Add subspecies nigriscapularis.	TAX	Black-shouldered Nightjar Caprimulgus nigriscapularis is treated as the northern subspecies of C. pectoralis based on similar vocalizations and lack of significant morphological differences (Louette 1990; Dowsett & Dowsett-Lemaire 1993; Zimmerman et al. 1996; Dickinson & Remsen 2013; Jackson 2013; HBW/BirdLife).

ADD	Recognize alagoanus as a distinct subspecies (Dickinson & Christidis 2014; del Hoyo & Collar 2016; contra Remsen 2003).Genetic (mtDNA) studies (Burney 2009) confirm it to be a distinct taxon included in the Xenops genibarbis group rather than a form that is synonymous with X. minutus minutus as previously treated (Remsen 2003).
Thorn-tailed Rayadito	Aphrastura spinicauda	Add subspecies subantarctica.	ADD	Described as sp. nov.: Rozzi et al., 2022, based on genetic, morphological, and ecological divergence. Tentatively treat as a subspecies of Aphrastura spinicauda pending formal SACC evaluation.
Golden-crowned Flycatcher	Myiodynastes chrysocephalus	Reassign subspecies minor and cinerascens to Golden-bellied Flycatcher Myiodynastes hemichrysus.	TAX	Reassign subspecies minor and cinerascens from Golden-crowned Flycatcher M. chrysocephalus to Golden-bellied Flycatcher M. hemichrysus because vocalizations are identical to nominate M. h. hemichrysus and unlike those of M. chrysocephalus (del Hoyo & Collar 2016; HBW/BirdLife).

Black-backed Swamphen	Porphyrio indicus viridis	Porphyrio poliocephalus viridis	TAX	"The taxonomic status of populations in South-East Asia [treated as subspecies viridis] is complex and poorly understood" (Sangster, 1998). It is a variable form “intermediate between poliocephalus and indicus resembling the former in the color of the head and neck and the latter in other plumage” (Taylor, 1998). They are individually variable in regards to mantle color and the degree of grey on the sides of the head (Wells, 1999). Traditionally associated with the “indicus” group (i.e. Roselaar in Cramp et al, 1980; Ripley, 1977; Sangster, 1998, Garcia-R. and Trewick, 2015), but many individuals are inseparable in the field from poliocephalus and most more closely resemble poliocephalus than indicus. Thus, assignment to indicus would seem arbitrary based merely on phenotypic characteristics. No specimens from southeast Asia were included in the recent genetic study of this group (Garcia-R. and Trewick, 2015). Tentatively treated here as a subspecies of poliocephalus pending more definitive studies. Porphyrio indicus becomes monotypic.
