v2025 errata
CHECKLIST ERRORS
- Cloven-feathered Dove: Ptilinopus holosericea → Ptilinopus holosericeus [28 June 2025]
- This name should be corrected to Ptilinopus holosericeus, since Ptilinopus is masculine. This was an unintended error for v2025 of AviList and will be corrected in the next version; eBird/Clements v2025 will use Ptilinopus holosericeus (v2024 retained this species in Drepanoptila).
- White-bellied Goshawk: Tachyspiza haplochrous → Tachyspiza haplochroa [28 June 2025]
- This name should be corrected to Tachyspiza haplochroa, since Tachyspiza is feminine. IOC 14.2 and eBird/Clements v2024 both spell this correctly, so this was an unintended oversight for v2025 of AviList and will be corrected in the next version.
- Little Lorikeet Parvipsitta pusilla and Purple-crowned Lorikeet Parvipsitta porphyrocephala: Parvipsitta → Psitteuteles, thus removing Parvipsitta from the checklist [28 June 2025]
- As indicated by our Decision Summary (no. 662; “a polytypic Psitteuteles, with P. versicolor, P. pusillus, and P. porphyrocephalus”) we intended to treat Little Lorikeet and Purple-crowned Lorikeet in Psitteulteles rather than in Parvipsitta. These names are correctly shown in eBird/Clements v2024 and will be updated for AviList v2026.
- The scientific name for Little Lorikeet should be corrected to Psitteuteles pusillus
- The scientific name for Purple-crowned Lorikeet should be corrected to Psitteuteles porphyrocephalus
- Total count of genera reduced by one to 2,375
- As indicated by our Decision Summary (no. 662; “a polytypic Psitteuteles, with P. versicolor, P. pusillus, and P. porphyrocephalus”) we intended to treat Little Lorikeet and Purple-crowned Lorikeet in Psitteulteles rather than in Parvipsitta. These names are correctly shown in eBird/Clements v2024 and will be updated for AviList v2026.
- AviList English names for seven Turdus from the Island Thrush split are erroneous [31 July 2025]
- After then 17-way split of Island Thrush, provisional and incorrect names were published by AviList, despite consensus names being agreed-to by eBird/Clements, IOC World Bird List, and BirdLife International. These names were not intentional and will be corrected for v2026.
- Turdus nigrorum: change Negros Island Thrush to Mindanao Island Thrush
- Turdus schlegelii: change Sulawesi Island Thrush to Wallacean Island Thrush
- Turdus javanicus: change Sunda Island Thrush to Sundaic Island Thrush
- Turdus deningeri: change Sula Island Thrush to Moluccan Island Thrush
- Turdus kulambangrae: change Guadalcanal Island Thrush to Solomons Island Thrush
- Turdus vanikorensis: change Vanuatu Island Thrush to Vanikoro Island Thrush
- Turdus pritzbueri: change Loyalty Island Thrush to White-headed Island Thrush
- After then 17-way split of Island Thrush, provisional and incorrect names were published by AviList, despite consensus names being agreed-to by eBird/Clements, IOC World Bird List, and BirdLife International. These names were not intentional and will be corrected for v2026.
- Erroneous range statements were inherited from the eBird/Clements checklist for the two subspecies of Western Yellow Robin Eopsaltria griseogularis, which were actually reversed, and shoudl be corrected as shown below. [13 August 2025]
- Eopsaltria griseogularis griseogularis: southwestern Australia (Shark Bay to Eyre Peninsula, South Australia; excludes forested southwest) –> southwestern Australia (forests from Perth to Albany)
- Eopsaltria griseogularis rosinae: southwestern Australia (forests from Perth to Albany) –> south-central Australia (Shark Bay to Eyre Peninsula, South Australia; excludes forested southwest)
DECISION SUMMARIES
- Western Black-eared Wheatear Oenanthe hispanica and Eastern Black-eared Wheatear Oenanthe melanoleuca [28 June 2025]
- Decision Summary no. 162 in the v2025 sheet and in Decision Summaries sheet erroneously refers to the species limits in the Oenanthe lugens complex, but should refer to the split of O. melanoleuca from O. hispanica. Please replace the existing Decision Summary with this one:
- Taxon melanoleuca (monotypic) is treated as a species separate from Oenanthe hispanica (monotypic) based on genetics (Aliabadian et al. 2012; Kakhki et al. 2018; Schweizer et al. 2019a, b; Zhao et al. 2023).
- Decision Summary no. 162 in the v2025 sheet and in Decision Summaries sheet erroneously refers to the species limits in the Oenanthe lugens complex, but should refer to the split of O. melanoleuca from O. hispanica. Please replace the existing Decision Summary with this one:
- Dusky-cheeked Fig-Parrot: Nannopsittacus melanogenia [28 June 2025]
- This name deserved a decision summary, since some experts disagree on the correct nomenclature of this taxon and prefer Nannopsittacus melanogenius. For v2026 we will add this Decision Summary to establish the opinion that led to the usage of Nannopsittacus melanogenia. If this issue needs reconsideration, then the AviList Bibliographic and Nomenclature Committee will gladly consider a formal proposal. Please add this decision summary to this species using new issue N-78; please also add N-78 to the Decision Summaries page.
- The original name, melanogenia, can variably be interpreted as a Latinized adjective or a noun in apposition. In such cases, ICZN Article 31.2.2 stipulates noun usage, making the name melanogenia inalienable.

- Corvinella, Urolestes, and Lanius [28 June 2025]
- The Decision Summary for genera Corvinella, Urolestes, and Lanius (issue 1166) required two minor edits that were not reflected in the published version; corrections are noted below (with new text in bold)
- Corvinella and Urolestes are accepted as monotypic genera, rather than being placed in Lanius, pending further research. Although
mitochondrialmitochondrial-dominated (Fuchs et al. 2019) and genomic DNA (McCullough et al. 2023) data suggest that these highly sociable and distinctly-plumaged birds are deeply diverged from Lanius,taxon sampling is incomplete andphylogenetic relationships remain poorly resolved.

Minor Corrections
- For Cozumel Thrasher Toxostoma guttatum the Extinct_or_possibly_extinct value has a minor capitalization error: “(Possibly extinct)” should be “(possibly extinct)”. [28 June 2025]
- For Spectacled Flowerpecker Dicaeum dayakorum, the authority should read “Saucier, JR; Milensky, CM; Caraballo-Ortiz, MA; Ragai, R; Dahlan, NF; Edwards, DP” rather than “Saucier JR; Milensky, CM; Caraballo-Ortiz, MA; Ragai, R; Dahlan, NF; Edwards, DP” [28 June 2025]
- For Rosy Minivet Pericrocotus roseus we incorrectly published avibase-DC3BACCD but should have used avibase-C6FB6CF9. The difference hinges on whether the taxon stanfordi is treated as included in P. roseus or as a hybrid with Brown-rumped Minivet P. cantonensis and thus not part of the circumscription of P. roseus; decision summary no. 1243 reads: “Taxon stanfordi has sometimes been recognized as a subspecies of Pericrocotus roseus (e.g., Clements et al. 2019), but has more recently been treated as a hybrid between P. cantonensis and P. roseus (Taylor 2023) and we follow that treatment here.” AviList v2025 and eBird/Clements v2024, among others, are aligned in explicitly excluding stanfordi and thus must use avibase-C6FB6CF9.

(Some additional reported errors are being reviewed and will be added here once confirmed; many of these however represent intentional nomenclatural decisions that remain to have documentation added.)
