Richard, thanks

I guess it's no surprise that application of the Tobias et al criteria lead to a mass Toucan split-fest. The Trumpeter splits are interesting - have they ignored the Dark-winged Group or not found enough to warrant the splits there? At least some of the additional cis-andean splits (eg Crimson-bellied pecker) have been previously suggested/implemented by others.

cheers, alan

As throughout this thread, we're getting a series of partial previews of BirdLife's taxonomic overhaul of the non-passerines where evident from specific RFIs re threat status. But the complete picture is still rather uncertain...

However, John Boyd (TiF) recognises Psophia (viridis) obscura as a distinct species, but not P (v) dextralis or P (v) interjecta.

Violaceous Trogon

Snapdragyn said:
Any word on why they're relumping the just-split Violaceous Trogon?
Click to expand...
The existing BirdLife Species factsheet notes that "Trogon violaceus (Sibley and Monroe 1990, 1993; Stotz et al. 1996) has been split into T. violaceus and T. caligatus following SACC (2009), and into T. violaceus and T. ramonianus following SACC (2010)".

The recent BirdLife Globally Threatened Bird Forums post merely states that "BirdLife's taxonomic treatment of a number of taxa occurring in the Amazonia region has been revised following the application of criteria set out by Tobias et al. (2010)". Presumably T (v) caligatus and T (v) ramonianus didn't score the minimum of 7 points required to support species status when reassessed by the BirdLife Taxonomic Working Group. The post also reaffirms that "Full details of the specific scores and the basis of these for each new taxonomic revision will be provided in the [new] Checklist" – publication date currently stated as Aug 2014 (Vol 1: Non-passerines).

Incidentally, I'm a little surprised by the approach that BirdLife and Lynx are taking to revising the taxonomy for the new checklist, stating that "Following publication, an open and transparent mechanism will be established to allow people to comment on the taxonomic revisions or suggest new ones...". Surely it will then be rather late – the wholesale (and sometimes controversial) revisions will have been enshrined in a lavish and expensive book which will presumably remain in print for many years...

PS. Lumping means that Lynx doesn't need to produce artwork for ramonianus (not illustrated in HBW 6). ;)

Amazona (farinosa) guatemalae – Blue-crowned (Mealy) Amazon – confirmed

I wonder where subspecies virenticeps falls in this split

BirdLife...
A. guatemalae is present along the Caribbean slope of Middle America, from Veracruz and Oaxaca south to western Panama, and also found on the Pacific slope of Costa Rica and western Panama (Juniper and Parr 1998, Forshaw 2006, 2010).

So BirdLife's Amazona (farinosa) guatemalae includes ssp virenticeps.

Ref: Collar 1997 (HBW 4).

probably used the wrong phrasing.

reading it again it sounds like I meant "It's not a surprise they split the New Zealand Dotterel"

Where I meant to phrase it as "They split the dotterel...does anyone else find that surprising?"

This is why all my papers go through about 3 or 4 editorial passes before I show anyone...
 
HBW & BirdLife Illustrated Checklist

Further details now on the Lynx website: HBW and BirdLife International Illustrated Checklist of the Birds of the World.
Taxonomic Results
In this Checklist, a modern, broad version of the Biological Species Concept (BSC) has been applied, with the aid of the scoring system to evaluate differences in morphology, vocalizations, ecology and geographical relationships published in Ibis by Tobias et al. (2010)*. For the non-passerines, this has resulted in relatively few lumps (21) but a much higher number of splits, 461 in total at the time of writing, compared with the taxonomy presented in the HBW series. Groups with major changes in species numbers include:
  • Pigeons: 46 splits, e.g. Western Spotted Dove Spilopelia suratensis
  • Hummingbirds: 36 splits, e.g. Apurimac Starfrontlet Coeligena albicaudata
  • Seabirds: 32 splits, e.g. Spectacled Petrel Procellaria conspicillata
  • Owls: 26 splits, e.g. Tanimbar Boobook Ninox forbesi
  • Kingfishers: 29 splits, e.g. Black-headed Kingfisher Actenoides capucinus
  • Barbets: 24 splits, e.g. Turquoise-throated Barbet Psilopogon chersonesus
  • Woodpeckers: 39 splits, e.g. Johnston's Woodpecker Dendropicos johnstoni
  • Parrots: 45 splits, e.g. Creamy-breasted Fig-parrot Cyclopsitta amabilis

Newly revealed...
  • Spilopelia (chinensis) suratensis – Western Spotted Dove
  • Ninox (squamipila) forbesi – Tanimbar Boobook (Moluccan Hawk-owl) [IOC]
  • Psilopogon (asiaticus) chersonesus – Turquoise-throated (Blue-throated) Barbet
  • Dendropicos (elliotii) johnstoni – Johnston's (Elliot's) Woodpecker
  • Cyclopsitta (gulielmitertii) amabilis – Creamy-breasted (Orange-breasted) Fig-parrot

:t: Richard, thank you very much. I appreciate your summary.

It's going to be a hefty volume. Size as given as 31x24cm, so a smaller format than the main HBW series. The specimen plates have 15 species on a double page spread, so, with 5000 species per volume, that will mean towards 700 pages per volume [they state 800: perhaps 15 per spread is more than average]. It would be interesting to know what were the deciding factors that drove the final choice of number of volumes, pages per volume, species per page, format. It cannot have been easy. However, it looks impressive. I like the attention to detail in the layout. I will be buying it as soon as they are ready to take my hard-earned.
