BirdLife's Globally Threatened Bird Forums, 31 Jul 2013: Preliminary decisions for the 2013 Red List.

Despite the numerous BirdLife posts since Nov 2012 announcing new splits based on Tobias et al 2010, the only additional species in the spreadsheet are Tsingy Wood Rail Canirallus beankaensis (ex-NR) and Pernambuco Foliage-gleaner Automolus lammi (ex-UR).

Have all the proposed splits been deferred/abandoned...?

Too much detail to get through by people with other work to do?

A cynic might conclude that the splits have been conveniently deferred until after publication of Vol 1 of the HBW/BirdLife Illustrated Checklist, thus avoiding the need to rapidly produce new artwork and maps.

I was thinking that myself, especially after the aborted (?) Variable Dwarf Kingfisher split-fest.

Joe Taylor, BirdLife, 1 Aug 2013...

Dear all,

Preliminary decisions have been posted on the Globally Threatened Bird Forums

A great many thanks to those who have already posted comments on the forums for this round of decisions, particularly to those who were contacted at short notice. Your input is vital to the Red List assessments that we carry out and the comments posted on the forums have allowed us to reach preliminary decisions for 63 species.

Please visit the forums to review the list of preliminary decisions.

There is now a period of two weeks for comments on our preliminary decisions and further comments on discussion topics. The final deadline for comments is Monday 19 August, after which we will post final decisions. Updated factsheets and Red List assessments for species receiving final decisions will be published in the 2013 Red List update in November.

Decisions for species that require further input will be pended until the next round, which is likely to take place early in 2014. The exact timeline will be announced later this year.

Taxonomic changes in the non-passerines
You will note that during this round we are not making decisions on the newly-defined non-passerine species resulting from the application of the Tobias et al. (2010) criteria. Decisions on these species will now be undertaken in the next round and their Red List assessments are due to be published in the 2014 Red List update, which is expected to be launched in spring of next year. Further topics on newly-defined non-passerine species are expected to be posted over the coming months, so please check the forums regularly to keep track of the discussions underway. Note that it is possible to set up RSS feeds to receive automatic email alerts to new topics being posted in any of the regional or species categories – see the 'feedburner' links at the top of each page, copy the relevant link into your internet browser and follow the instructions from there.

Globally Threatened Bird (GTB) Forums website
The forums can be found at www.birdlife.org/globally-threatened-bird-forums. Please read the welcome and instruction pages for more details.

To read and contribute to discussions on the species under review, visit the forums at www.birdlife.org/globally-threatened-bird-forums

Click each link to view a discussion topic on each species or taxonomic change, giving the rationale for the status review or a request for information.

Make your contribution through the forum by typing it in the box below the topic, and then clicking "Post a comment" (there is no need to register or create a user account). Posts are then added subsequently by forum moderators (therefore there may be a delay before your posting appears on the site). For contributions that are used, your name and affiliation will be explicitly acknowledged in the species accounts that will appear on the BirdLife and IUCN websites, and in future publications.

The new and revised species assessments and updated factsheets will be released subsequently on the BirdLife website and incorporated into the IUCN Red List.

To maximise feedback, please distribute this message as quickly and widely as possible to relevant people within your networks.

Note that the selected species under discussion are those for which newly published information is available (or new unpublished information has been sent to BirdLife) that implies a revision may be appropriate given the IUCN Red List criteria and quantitative thresholds, or a taxonomic change has occurred, triggering new Red List assessments. If you would like to propose additional species to be reviewed, please post a comment on the relevant 'Suggestions for new topics' discussion, or email andy.symes AT birdlife.org, in either case giving details of population/range size or trend estimates that may require revision.

For more general information about the GTB Update, visit http://www.birdlife.org/action/science/species/global_species_programme/gtb_forums.html

Anyone wishing to comment via email rather than through the forum process is welcome to do so.

Many thanks again for your participation in the Red List process.

From the BirdLife Red List team

Is Lynx sure that the first volume of this book will be released this year? I've found absolutely no information about the price and the release date so far. There is not even an announcement at the upcoming books section at the Lynx page.

Unlikely I think. Lynx would be getting pre-publication leaflets out by now if it was (normally 6 months before?). Must be 2014.

HBW/BirdLife Illustrated Checklist

Today (with the latest issue of Dutch Birding) I received the HBW Alive leaflet featured on the Lynx webite, reinforcing the message that "Later in 2013, hundreds of changes will be automatically incorporated upon the publication of the first volume of the Checklist".

But as Alan suggests, this seems extremely unlikely, given both the lack of advance publicity, and possible delays in updating the BirdLife checklist to include Tobias et al 2010-based taxonomic revisions (which Lynx has highlighted as an innovative feature of the illustrated checklist).

From HBW alive (Wandering Albatross):

The taxonomy presently employed in HBW Alive is identical to that of the HBW volumes but will change automatically following the publication, planned for early 2014, of the HBW and BirdLife International Illustrated Checklist of the Birds of the World, to which all HBW Alive treatments of taxonomy and classification will be permanently linked. It will be possible to compare any taxonomic changes with the original HBW treatment, since this will remain available in HBW Alive.

Well spotted, jalid. That statement has evidently been included in all the species accounts for Diomedea (which includes Phoebastria and Thalassarche in HBW taxonomy).

Will both volumes (Non-Passerines and Passerines) will be released next year or will the Passerines volume postponed to 2015?

I expect that there will be at least a year between publication of the two volumes, given that in 2012/2013 BirdLife has announced taxonomic revisions only for the non-passerines.

2013 Red List final decisions

BirdLife's Globally Threatened Bird Forums, 3 Sep 2013: Final decisions for the 2013 Red List.

Re-categorised as NR (Not Recognised), ie lumped:

Neomorphus (geoffroyi) squamiger - Scaled Ground-cuckoo
Tyto (novaehollandiae) sororcula - Lesser Masked-owl
Tyto (novaehollandiae) manusi - Manus Masked-owl

Maroon-faced Parakeet Pyrrhura leucotis is re-categorised as 'NA'...?

Melanie · Sep 3, 2013

I've never thought that the decision process is so difficult. 99 decisions are postponed to 2014 (or maybe 2015? nobody knows it for shure)

Richard Klim · Sep 3, 2013

Melanie said:

...and that's excluding the numerous Tobias et al 2010-based non-passerine splits (which have also been deferred to 2014).

It is not only strange but also upsetting that they choose to lump both Lesser Masked-owl and Manus Masked-owl with Australian Masked-Owl purely based on the comments made in Poulsen et al., 2013? it is obvious that a thorough revision of the whole species complex is needed!

As Phil Gregory pointed out in another thread would not make sense biographically to treat the Manus Masked-owl as a subspecies of the Australian Masked-Owl (the closest populations is found in the southern lowlands of New Guinea). Seeing as there has been no confirmed records of this species since 1934, it is clearly very localized and in need of conservation efforts.

Indeed, I assume if they lump Lesser Masked, then Seram Masked will also be lumped? As that is certainly looks like part of the sororcula complex.

It seems absurd to lump Manus Masked Owl unless some new information has come to light, it is biogeographic nonsense for one and this is potentially a Critically Endangered taxon, why on earth would it now be lumped? The whole trend with owls has been multiple splits as further knowledge has emerged, i find it baffling that this has been done, so much for transparency of process! Can someone at Birdlife please tell us why? I'm currently in New Caledonia and won't have time to chase this up but it shouldn't be left set in stone without justification being offered.

James Eaton said:

Jønsson et al 2013 describes Seram Masked-Owl Tyto almae as a new species, but suggests the lumping of T sororcula and T manusi.

Based on evidence from genetic divergences and plumage patterns, and to a lesser extent morphometrics and vocalization of Moluccan and Australo-Papuan masked-owls, it is apparent that a tight-knit assemblage including Tyto novaehollandiae, T. sororcula and T. manusi may be considered a single species, which should be referred to as Tyto novaehollandiae.

IOC has taken the opposite approach: retaining T sororcula and T manusi, but treating almae as a subspecies (of T sororcula) "pending revision of species complex":
www.worldbirdnames.org/updates/subspecies/

eBird/Clements and HBW treat all three taxa as species.

[BirdLife hasn't stated a position re almae.]

I agree with this, although assume BLI are placing a great deal of weight on the recent DNA evidence? It is probably one of the anomalies of applying Tobias et al. uniformly that occasionasionally there is a counterintuitive result?

cheers, alan

Counterintuitive, certainly - rather like "occasionasionally"?:t::eek!:
