The final deadline for comments on this topic is 19 May 2014.
This is part of a consultation on the Red List implications of extensive changes to BirdLife’s taxonomy for non-passerines
Lynx Edicions and BirdLife International will soon publish the HBW-BirdLife Illustrated Checklist of the Birds of the World, building off the Handbook of the Birds of the World series, and BirdLife’s annually updated taxonomic checklist.
The new Checklist will be based on the application of criteria for recognising species limits described by Tobias et al. (2010). Full details of the specific scores and the basis of these for each new taxonomic revision will be provided in the Checklist.
Following publication, an open and transparent mechanism will be established to allow people to comment on the taxonomic revisions or suggest new ones, and provide new information of relevance in order to inform regular updates. We are also actively seeking input via a discussion topic here regarding some potential taxonomic revisions that currently lack sufficient information.
The new Checklist will form the taxonomic basis of BirdLife’s assessments of the status of the world’s birds for the IUCN Red List. The taxonomic changes that will appear in volume 1 of the checklist (for non-passerines) will begin to be incorporated into the 2014 Red List update, with the remainder, and those for passerines (which will appear in volume 2 of the checklist), to be incorporated into subsequent Red List updates.
Preliminary Red List assessments have been carried out for the newly split or lumped taxa. We are now requesting comments and feedback on these preliminary assessments.
Six [edited from five on 16 May 2014] Extinct species are being re-categorised as Not Recognised:
Ara gossei, A. atwoodi, A. guadeloupensis and A. erythrocephala (BirdLife species factsheets): These four species are to be removed from the BirdLife list of accepted species based on the study by Wiley and Kirwan (2013) into the existence of extinct macaw species in the West Indies.
Dysmoropelia dekarchiskos (BirdLife species factsheet): Subfossil evidence from St Helena indicates that this species probably became extinct before or during the Last Glacial Maximum (Lewis 2008), thus the species is to be re-categorised by BirdLife as Not Recognised and removed from the list of species known or thought to have been extant post-1500 AD.
Gallicolumba norfolciensis (BirdLife species factsheet) [added to this topic on 16 May 2014]: Subfossil remains from Norfolk Island identified as a species of Gallicolumba (Higgins and Davies 1996, Rich et al. 1983) (but possibly referring to an Alopecoenas sp. [D. Schodde in litt. 2014 per A. Elliott in litt. 2014], have been linked with a painting by J. Hunter from 1790 (Hindwood 1965), which may have served as basis for part of the description of Columba norfolciensis by Latham in 1801. The description also drew on correspondence from 1788–1790, referring to a small terrestrial dove that was common and tame. These various indications may or may not refer to the same species, and the original description appears to be composite, perhaps referring to both Columba leucomela (infrequent vagrant to Norfolk Island) and Chalcophaps longirostris (present on Norfolk Island, possibly introduced) (Schodde and Mason 1997). Owing to the lack of type specimen for Columba norfolciensis, the uncertain identity and confused usage, spanning three rather different genera, this name has now been formally suppressed (Schodde et al. 2007, ICZN 2010, Dickinson and Remsen 2013).
Twelve taxa [corrected from 11 on 1 May 2014] are being newly recognised as Extinct species following descriptions and evidence that they are likely to have remained extant post-1500 AD:
Chenonetta finschi: Holdaway et al. (2002) present evidence that this species could have remained extant in New Zealand post-1500 AD.
Nyctanassa carcinocatactes: This species was described from fossils found on Bermuda and is presumed to relate to herons noted by early travellers after the human settlement of Bermuda in 1612 (Olson and Wingate 2006).
Bermuteo avivorus: Described from fossils found on Bermuda and thought to relate to raptors observed in 1603 (Olson 2008).
Dryolimnas augusti: Described from fossils from Reunion by Mourer-Chauviré et al. (1999) and thought to correspond to a rail species mentioned by Dubois (1674 per Mourer-Chauviré et al. 1999) as Râle des Bois.
Tribonyx hodgenorum: Described from fossils found in New Zealand, the most recent of which date from c.1700 (Cassels et al. 1988).
Porphyrio paepae: Described by Steadman (1988) from bones found at archaeological sites on Hiva Oa and Tahuata. These fossils are thought to relate to a flightless bird seen on Hiva Oa on a single occasion in 1937 (Heyerdahl 1974 per T. Tyrberg in litt. 2014).
Columba thiriouxi: Described from fossils found on Mauritius that presumably relate to wood pigeons mentioned by early visitors to the island (Cheke and Hume 2008).
Alectroenas payandeei [added to this topic on 1 May 2014]: The species is likely to have gone extinct during the 17th century, but before the first detailed faunal list was made by Leguat in 1691-1693 (Hume 2011).
Nesoenas cicur: Described from fossils found on Mauritius that presumably relate to the “tourterelles” noted in the early 18th century (Cheke and Hume 2008, Hume 2011).
Eclectus infectus: This species is described by Steadman (2006a) from bones found at archaeological (late Holocene) and paleontological (late Pleistocene) sites on three islands in Tonga, and presumably relates to a drawing of a parrot from the Malaspina expedition to Vava’u, Tonga in 1793 (Steadman 2006b, Olson 2006).
Aegolius gradyi: Described from fossil remains from Bermuda by Olson (2012), who in reviewing accounts dating from the early 1600s, considers it likely to have persisted into the historic period.
Colaptes oceanicus: Described from fossils from Bermuda by Olson (2013), who in reviewing historic accounts, regards the species as likely to have persisted into the colonial period (1600s).
