Thanks Nikolas,

I see there being two conflated issues here.
One is the ongoing taxonomic revisions that affect species that regularly occur in Australia - species that either breed in Australia or are regular migrants/visitors to Australia. The other is the official recognition of observations of vagrants in Australian territory. These are often only made in external territories and infrequent / "one-offs" - the "recent sightings of Asian Stubtail, Eastern Crowned Warbler" you cite are a good case in point.

IOC lumps and splits is the key issue for twitchers who want to keep their lists up to date. The addition of vagrants to the Australian list is a separate matter.

Regards, Laurie.

Hi Paul,


Yes, as I said, the OZ-list is a dynamic list as well and it is meant to follow the latest IOC decisions (currently 3.1). But this doesn't only mean that it will be frequently updated with the latest IOC decisions but also with additions to the OZ list such as the recent sightings of Asian Stubtail, Eastern Crowned Warbler... Therefore there may be a (slight or not so slight) delay in the dynamic.

Cheers,

Nikolas

Thanks Nikolas, that was the list that I was using – however, now I have some further concerns.

A number of people have told me that the Quail-thrush splits I mentioned have been accepted by IOC in the latest release. On checking the BARC spreadsheet, I note that these are not listed as official splits in that list – which is based on IOC 2.9 – whereas they are split in the latest IOC 3.1 list that I have downloaded from http://www.worldbirdnames.org/

So, this begs the question – IF Australia is to use IOC going forwards, are we to use the most current IOC checklist, or do we use the checklist based on IOC 2.9 with some amendments posted on the BARC page? In my opinion, if we’re to use IOC we should be using the current IOC checklist.

Hi Paul et al.,

An IOC-based OZ list compiled by David James is on the BARC website: 
http://www.tonypalliser.com/barc/barc-home.html
Similar to the IOC list itself, this one is a dynamic list. So, keep checking.

Cheers,

Nikolas

Hi birders,



Following is my analysis of the splits that are supported by IOC but not by
Christidis and Boles:



Antipodean Albatross (split from Wandering Albatross)

Northern Royal Albatross (split from Royal Albatross - and Royal Albatross
renamed Southern Royal Albatross)

Campbell Albatross (split from Black-browed Albatross)

Salvin's Albatross (split from Shy Albatross)

Chatham Albatross (split from Shy Albatross)

Indian Yellow-nosed Albatross (split from Yellow-nosed Albatross - and
Yellow-nosed Albatross renamed Atlantic Yellow-nosed Albatross)

Western Grasswren (split from Thick-billed Grasswren)

Hornbill Friarbird (split from Helmeted Friarbird)

Swan River Honeyeater (split from White-naped Honeyeater)



And the following are proposed splits, I believe:



Western Quail-thrush (split from Chestnut-breasted Quail-thrush)

Nullabor Quail-thrush (split from Cinnamon Quail-thrush)

Western Shrike-tit (split from Crested Shrike-tit)



Can anyone with more taxonomic experience than me please confirm these
splits? Have I missed any splits that anyone knows about? Also, are there
any lumps under IOC?
