I wonder if there will be any 'novel' splits or whether there will 'just' be further convergence with the IOC list. We'll see..

cheers, alan

Presumably it'll be all the updates from the last AOU change a couple of months ago (split Lesser Redpoll, etc.)

Personal question chaps, don't worry, not 'how big is it' your list that is.......

I decided long ago to adopt the IOC like many others and I just do not have the inclination to keep abreast of the others, so, can I ask why so many, so closely follow the other list changes, updates etc when it's not the list you keep?

Is it curiosity, is it so you can compare your Clements list to someone elses even though you use the IOC or vice versa? Do you submit lists to be ranked in each list or just keep a note yourself, just seems like a lot of work to me!

In my case I keep track of several lists and I keep track of what species I've seen in all of them. It's a lot of work getting that set up, true (but it's a pretty harmless hobby). But once it's set up then applying the updates isn't a lot of work. For example once I put in the changes lumping Thayers Gull with Iceland Gull, my lists are automatically recalculated.

No criticism intended, I just know how much work it would be and I couldn't be bothered with it.

I follow IOC but keep track of Clements/ebird for several reasons

1) I like the "groups" that Clements uses, and keep track of these in case of future splits. IOC lists subspecies but does not having any sort of system that breaks subspecies into potential future splits, etc

2) It can be interesting to see where and how lists deviate, which can provide a sense of future taxonomic changes down the line.

The eBird site says: "The annual eBird taxonomy update IS CURRENTLY UNDERWAY (Tuesday, 15 August). It is best if you DO NOT change your records for recent splits etc. until the taxonomy update is complete." But I just checked and I have seen an Iceland Gull in San Luis Obispo County! Just sitting in my armchair I became a much better birder. I tried unsucessfully for years to turn Thayer's Gulls into Iceland Gulls , eBird did it for me with the turn of a switch.

As I think you are aware, ALL Thayer's gulls were turned into Icelands ...

Quite curious to see the Clements 2017 update, eBird gave me a couple anticipated armchair ticks today and one unanticipated. No clue where or what...

Clements 2016 -> 2017 differences

If people want to wade through in advance of the official announcement, here's a full set of differences (see the attached file). This is based on the API (http://ebird.org/ws1.1/ref/taxa/ebir...v&locale=en_US) diffed against the prior year's, and includes:
  • Differences in sequence
  • Differences in scientific name
  • Differences in common name

... and of course the always much-desired splits and lumps.

Lines starting with ">" are the old taxonomy, lines with "<" the new taxonomy (and everything else are sequence numbers etc.)

Thanks! Had a quick glance and must have missed a lot, but I see a fairly modest update, dominated by hypnen revision! A quick glance at the list reveals (apart from NACC-changes, nomenclature issues plus English name changes, including the hyphens):

Splits
* Alignment with IOC
Arborophila campbelli
Arborophila rolli
Arborophila sumatrana
Collocalia splits
Eugenes spectabilis
Eunymphicus uvaeensis
Scytalopus alvarezlopezi
Turnagra split
Ptiloris intercedens
Pycnonotus conradi
Iole charlottae
Iole cacharensis
Zosterops ponapensis
Montecincla jerdoni
Montecincla meridionalis
Calliope tschebaiewi
Geospiza acutirostris
Geospiza septentrionalis
Geospiza propinqua
Melozone cabanisi

* New stuff (all are or have been IOC potential splits)
Myzomela nigriventris
Lophorina niedda
Lophorina minor

Lumps
Cyanomitra obscura is the only one I could find!

Generic changes
* Alignment with IOC
Anser-geese, Anas-ducks, Dendroperdix, Tetrastes, Ardea intermedia, Haliaeetus, Anous, Alopecoenas (finally!), Juliamyia, Carpodacus-assemblage, Carduelini, Myiomela, Sholicola, Montecincla.

* New stuff (compared to IOC, not a single one outside NACC/SACC):
Pseudoscops clamator to Asio (but not Jamaican Owl)
Mazaria split from Synallaxis
Sphenocichla roberti to Stachyris (correcting past mistake)
Saltator atricollis to Saltatricula
Hemispingus/Poospiza-mess
Diuca speculifera to Idiopsar
Phrygilus concolor & plebejus
Haplospiza rustica to Spodiornis
Ixothraupis split from Tangara (but not Stilpnia, which must leave the remaining Tangara paraphyletic, no?)
Cyanocompsa brissonii & cyanoides to Cyanoloxia

Do they still use Anas strepera or do they changed it into Mareca?

If I understand the lay-out properly it is now Mareca.

No changes to ordinal sequence? They passed on it last year and I thought for sure they would impose it in 2017 updates.

Yes, my recollection is they said they would do it this year.

Also slightly surprised they are adding a whopping 11 new families, 5 of which are from the Carribean:
Modulatricidae (Dapple-throat and Allies); Rhodinocichlidae (Thrush-Tanager); Passerellidae (New World Buntings and Sparrows); Calyptophilidae (Chat-Tanagers); Phaenicophilidae (Hispaniolan Tanagers); Nesospingidae (Puerto Rican Tanager); Spindalidae (Spindalises); Zeledoniidae (Wrenthrush); Teretistridae (Cuban Warblers); Icteriidae (Yellow-breasted Chat); and Mitrospingidae (Mitrospingid Tanagers).
All have been discussed/recognized by others, so none are individual surprises, but this will now mean global family listers following Clements/eBird will have to add Cuba and Puerto Rico to their destination lists, plus pay more attention to central america.

I also believe several of the families are among the youngest so far recognized.

I really like how they show their work by citing references and links to BHL and other websites of those references.

Most of those were part of this years AOU checklist update, so it makes sense they would show up in the ebird updates

True, I guess everything except Modulatricidae would be in the purview of the AOS (née AOU). Guess I was thinking that eBird/Clements would feel free to act more autonomously with respect to higher-level taxonomy, but that is probably not the case.

Great Gray Shrike...oh dear...*waits for Nutcracker to arrive*...

eBird: "Northern Shrike Lanius excubitor is split into two species. As with harriers, the familiar common names are retained for the New World and Old World, with the species of Europe and western Asia referred to as Great Gray Shrike Lanius excubitor and also retaining the scientific name. The species of the New World, Northern Shrike Lanius borealis has a scientific name change but shows no change in English name, retaining the preferred name in the Americas. However, Northern Shrike is very much a species of the Old World too, since it breeds west of central Siberia and northern Mongolia and winters widely in northern China, Japan, and Korea. Exact movements of the two species are complex and not well known, and field identification is very challenging, so Great Gray/Northern Shrike Lanius excubitor/borealis should be used liberally in Siberia, eastern Kazakhstan, and nearby areas. To add to the complexity, Northern Shrike has occurred as a trans-Atlantic vagrant to western Europe (e.g., the Azores) and also as a vagrant or rare winter visitor (Lanius borealis sibiricus) to Ukraine at least."

and did Collar et al. really assess every bird species...?

eBird:"Many new subspecies groups were added this year, largely because we reviewed the world by Nigel Collar and the Birdlife International team, who assessed every bird in the world based on morphological and acoustic information and scored their relative distinctiveness (also known as the Tobias criteria)."

Illustrated Checklist of the Birds of the World Vol 1 Introduction, page 33

"Our ambition...has been to apply the Tobias criteria as fully as possible the global avifauna. However...this would be more than the work of half a lifetime.
...we prepared candidate lists for taxonomic inquiry..."

Nit-picky I know but it's my birthday tomorrow...humour (note the u) me...
