I'm celebrating Leap Day by updating the list. I was unhappy with the previous treatment of Turdus, and a couple of new papers have helped matters.
It's still the case that I don't have the time necessary to do regular updates, so it will probably be a while before the next one.
Thrushes: There have been several taxonomic changes, as well as a general rearrangement of Turdus using Batista et al. (2020) and Nagy et al. (2019), as well as some adjustments to Catharus based on Everson et al. (2019).
- The Groundscraper Thrush, Turdus litsitsirupa, has been returned to genus Psophocichla.
- Ethiopian Thrush, Psophocichla simensis, has been split from from Groundscraper Thrush, Psophocichla litsitsirupa, based on Nylander et al. (2008) and the HBW Checklist.
- The Chinese Thrush, Turdus mupinensis, has been moved to the monotypic genus Otochichla based on Nylander et al. (2008), Nagy et al. (2019), and the HBW Checklist.
- Split Dagua Thrush, Turdus daguae, from White-throated Thrush, Turdus assimilis (Ridgely and Greenfield, 2001; IOC).
[Turdidae, Muscicapoidea II, 3.14]
Piculets: The Latin American piculets have been rearranged based on Shakya et al. (2017). Their results suggest that some adjustment of species limits will be needed, but that awaits further studies. A hybrid piculet I saw in Minas Gerais (Brazil) earlier this year suggests the issues go beyond found by Shakya et al.
Surprisingly, they found that the Olive-backed Woodpecker, Dinopium rafflesii, is sister to Gecinulus. As a result, I've placed it in the monotypic genus Chloropicoides (Malherbe 1848-49).
Other changes prompted by Shakya et al., include rearranging Piculus
and Yungipicus and adjusting the position of the Red-headed Flameback,
Chrysocolaptes erythrocephalus and of the Helmeted Woodpecker, Celeus
galeatus. Even though Shakya et al. (2017) and Dufort et al. (2016) have
differences in the overall arrangement of the woodpeckers, I continue to follow
Dufort et al. (2016) which seems to use more data.
[Picidae, Piciformes, 3.08]
Rails: The former Gray-necked Wood-Rail, Aramides cajaneus now goes as Gray-cowled Wood-Rail / Gray-necked Wood-Rail, Aramides cajaneus, with the former English name used by both the AOS NACC and SACC, and the latter used by IOC.
I've also rearranged the Laterallini based on tree B in Stervander et al. (2019). As a result, Atlantisia is merged into Creciscus and the Gray-breasted Crake returns to Laterallus as Laterallus exilis. [Rallidae, Gruae I, 3.04]
Dry Forest Sabrewing:
The Dry Forest Sabrewing, Campylopterus calcirupicola, is recognized as a
separate species related to the Gray-breasted Sabrewing, Campylopterus largipennis.
See SACC #756 and
Lopes et al. (2017). Lopes et al. and
suggest there are additional species in this complex. I saw this bird in June at
Lapa Grande State Park (Minas Gerais, Brazil).
[Trochilidae, Apodiformes, 3.10]
Cupwings: Pnoepygidae is now referred to as the Cupwing family. The English last names have been changed to reflect this. [Pnoepygidae, Paroidea & Sylvioidea I, 3.11a]
Today's changes are from AOS Supplements #58 and #59. These changes are NOT included in the latest CSV files. I did not adopt the Cassia Crossbill split because I have skepticism about it, even though it seems to have the strongest case of all potential North American Red Crossbill splits.
Thayer's Gull, Larus thayeri, has been lumped into Iceland Gull, Larus glaucoides
in accordance with the AOS 58th supplement.
[Laridae, Charadriiformes, 3.05]
The Chiriqui Foliage-gleaner, Automolus exsertus, has been split from
the Buff-throated Foliage-gleaner, Automolus ochrolaemus. See
AOS Supplement #59, which is based on the analysis of their response to calls by
Freeman and Montgomery (2017).
[Furnariidae, Furnariida II, 3.06]
Baird's Junco, Junco bairdi has been split from the Yellow-eyed Junco,
Junco phaeonotus as per the AOS 58th Supplement. The phylogeny follows
Friis et al., 2016), where Baird's Junco is not even sister to the Yellow-eyed
[Arremonidae, Core Passeroidea III, 3.05]
The White-collared Seedeater, Sporophila torqueola has been split into
Morellet's Seedeater / White-collared Seedeater, Sporophila morelleti and
and Cinnamon-rumped Seedeater, Sporophila torqueola based on the AOS 59th
Supplement and Mason et al. (2018). As with the Juncos above, they are not sister
[Thraupidae, Core Passeroidea V, 3.06]
Comparison Spreadsheet: Richard Jackson has provided an updated TiF-based spreadsheet cross-referenced to the IOC list, the 16 volumes of HBW, and the two volume HBW/BirdLife Illustrated Checklist (ICBW).
CSV Files: The CSV files have now been updated to version 3.10. These updates reflect changes to my personal list that have not been posted yet.
