Presumably that means they're waiting for more information to be published before they make a decision

I wish they wouldn't be so quick to remove things from the PS list. They are still proposed splits, just NACC hasn't recognized them yet. The jury is still very much out on if that was a right call for Great White Heron, and they will probably be getting more proposals to split somewhere down the line, requiring them to add it back to the PS list

Is this an error, I've always know this as Grey-capped Greenfich and that's what the IOC call it currently?

Aug 8 Post proposed split of Bonin Greenfinch Chloris kittlitzi from Grey-headed Greenfinch C. sinica.

 

[Paul Clapham]

It's "Grey-capped" in their 10.2 spreadsheet.

Sorry Paul,
what am I missing?

The proposal is to split from Grey-headed, that's the wrong name isn't it, should be Grey-capped?

[QUOTE The proposal is to split from Grey-headed, that's the wrong name isn't it, should be Grey-capped?[/QUOTE]

It's indeed a typo in the Diary. Should be Grey-capped. It's listed as that in the PS Page. Fixed in the Diary now.

Thanks David.

Aug 14 Post proposed lump of Scalloped Woodcreeper with Scaled Woodcreeper.

Aug 12 Post proposed split of Greyish Saltator into Northern, Caribbean and Southern Grey Saltators.

Aug 12 Post proposed lump of Northern and Southern Caracaras.

Here's one I've been waiting for

Aug 18 Post proposed split of Taiwan Bullfinch Pyrrhula owstoni from Grey-headed Bullfinch Pyrrhula erythaca.

 

[Andy Adcock]

With the ongoing debate surrounding eponyms, what is known of Owston of Pyrrhula owstoni, which is already called Owston's Bullfinch by some although the clear intention of the IOC is to not use that name.

The species from which the above will be split, is itself called Beavan's Bullfich in some books.

A bit here, though obviously written with some western bias:

[Andy Adcock]

Thanks Nutty, he seems fairly uncontrovertial, anything on Beavan?

Here you are: https://en.wikipedia.org/wiki/Robert_Cecil_Beavan


Trouble is, anything controversial tends to get deleted on wikipedia, unless they're really dreadful!

 

[Andy Adcock]

Thanks Nutty,
all very colonial and as such, will be detested by the usual lot even though there seems to be no scandal attached, apart from Empire that is.

"Beavan's Bullfinch"

Thanks Nutty, ... , anything on Beavan?

Here you are: https://en.wikipedia.org/wiki/Robert_Cecil_Beavan
...

Much more about "Beavan's Bullfinch" (and the birds named beavani) is to be read in the Bird Name Etymology sub-forum, in the thread The Eponym Dictionary of Birds (here, posts #50-64), from late January 2018, though note that the main focus in that certain thread are Jobling's scientific names, leaving the Bullfinch a bit off-side, somewhat neglected.

Also; note, regardless of what (English) Wiki says (last edited on 14 June 2020*), there's nothing (at least as far as I can tell) in the OD of Pyrrhula erythaca BLYTH 1862 (here), today's Gray-headed Bullfinch, a k a Beavan's Bullfinch, pointing clearly on who the dedicatee was/is.

German Wiki (updated "31. Dezember 2019)", is far more detailed (here).

But I still haven't figured out how Martin ("Taphrospilus"), who wrote most of the German Wiki entry, came to the conclusion that the common name "Beavan's Bullfinch" truly does commemorate Lieutenant** Robert Cecil Beavan ... and not his Brother Reginald ?!?

If anyone here, in this forum, does know of any certain evidence, pointing clearly at one or the other Lieut. Beavan, in a clear connection to this certain Bullfinch, please, feel free to join in.

If so, please keep any added info in the Bird Name Etymology sub-forum/thread. Simply to keep all "eggs in one basket".

The search goes on

** I doubt he ever reached the rank Captain (at least not while he was alive, he could, of course, have been brevetted Captain, posthumously, but if this ever took place I simply don't know). A Death Notice of "Mr ROBERT CECIL BEAVAN, Lieutenant ..." (here, bottom of page), and note the correction (in pencil scribblings) about his age!?! Someone sure seems to have known his true Birthday (i.e. 14 August 1841).

I see Balicassiao has been lumped with 2 of the other Hair-crested Drongo taxa. Shakya et al wrote ''The Palawan subspecies D. h. palawanensis constitutes Clade 4. Vaurie (1949) distinguished D. hottentottus from D. balicassius based on the appearance and complexity of feather ornaments. Genetic data, however, suggest a close relationship between D. hottentottus sub- species of the southern Philippines and D. balicassius of the northern Philippines. It is possible, however, that this closeness arises as a result of mtDNA introgression. A more extensive set of comparisons using nuclear loci is required to confirm D. hottentottus relationships within the Philippines Islands.'

Is this sentence enough to justify lumping these taxa? Why was this not included in the 'proposed lumps and splits'?

Has it Des, not on my version of the IOC list it hasn't?

It also lists five races of Balicassiao.

 

[Paul Clapham]

It was neither a split nor a lump. It's described in IOC's "Subspecies Updates" page:

Move subspecies samarensis and striatus to D. balicassius.

There are nine subspecies in the Hair-crested Drongo complex which have been batted back and forth between species over the years by various checklists, and this was just the latest instance of that, along with the splitting of palawanensis and cuyensis.

 

[Paul Clapham]

Looking a bit more, I also noticed that subspecies viridinitens was moved in 10.2. Comment in spreadsheet:

Move ssp. viridinitens from D. sumatranus to D. hottentottus (Shakya et al. 2020). Considered a separate species, Mentawai Spangled Drongo, by Eaton et al. (2016).

Thanks for catching that oversight, Paul. Added to Subspecies Updates for 10.2.
