AOU-NACC Proposals 2019 (2 Viewers)

Actually I think 2019 is correct, hence the proposals being named "2019-A, 2019-B" etc. An NACC "year" ends in July apparently and that's how they organize their proposals. There are usually three sets and we can expect a "2019-C" sometime in the matching Gregorian year.

Peter posted the 2018-C proposals by mistake. He's since deleted that post (and I've deleted mine highlighting the mistake).

Would anybody know what the "questions concerning the new name" Islerothraupis are ? (Perceived problems with the diagnosis ?)
 
And also

Proposals 2019-D (PDF)

2019-D-1a: Split Vermiculated Screech-Owl Megascops guatemalae: Recognize centralis as a separate species
2019-D-1b: Split Vermiculated Screech-Owl Megascops guatemalae: Recognize roraimae as a separate species
2019-D-1c: Split Vermiculated Screech-Owl Megascops guatemalae: Recognize vermiculatus as a separate species



This one has been done a while ago by the IOC where centralis is Choco Screech Owl, Roraimae is Foothill Screech Owl which includes pallidus and napensis?

Remaining races hastatus, cassini , fuscus, guatamalae and dacrysystactus become Middle American Screech Owl

The questions on the Isler's name comes from two troublmakers on the internet. l_raty & Andrew147 .

Andrew 10 March 2016:
A few of the 'un-named' taxa being discussed may already have existing names:
'Tachyphonus' cristatus, 'T'. rufiventer, 'T'. luctuosus = Loriotus, Jarocki 1821

[OD] (on p.133 -- or image #71), as a subgenus of Tanagra, type species by original monotypy Tanagra cristata "GL." (which I understand means "Gmelin/Linnaeus") = Tanagra cristata Linn. 1766. [OD].

The concept of American exceptionalism does not include spelling things correctly. The main list of AOS spells it correctly. Pink-legged Goose was added to the AOU check-list in 1910 from accidental records from Greenland. I never knew the AOS had a US check-list. Why? Pyle 2018 is here:
https://www.birdpop.org/docs/pubs/Pyle_et_al_2018_29th_Report_of_the_ABA_Checklist_Committee.pdf .
The Washington State bird record committee rejected Pink-footed.
REPORTS NOT ACCEPTED BY THE COMMITTEE - IDENTIFICATION
CERTAIN, ORIGIN UNKNOWN
Pink-footed Goose (Anser brachyrhynchus). Two Pink-footed Geese
were found with Canada Geese (Branta canadensis) and Greater Whitefronted Geese (Anseralbifrons) in Hoquiam, Grays Harbor County, from 5
November 2003 to 10 January 2004, when one bird disappeared (P.
Sullivan; photo: R. Sullivan). The second bird was last seen there on 11
January 2004. A Pink-footed Goose, presumably one of the Hoquiam birds,
was then found about 30 km away in Elma, Grays Harbor County, on 21
February 2005, where it remained until 10 April 2005. The Pink-footed Goose was critically endangered, with Svalbard populations plummeting to less than 5000 in the 1950s and Greenland/Iceland
populations reaching a nadir of 20,000-30,000 in the 1930s; by the mid1990s, the Svalbard population exceeded 38,000 and the GreenlandlIceland population had reached about 250,000 (Boyd 2005). This increase
was paralleled by an increase in reports from North America (American
Birding Association 2002), and though there are no North American records
west of Pennsylvania (American Birding Association 2002), Washington
lies directly on a 1800 misorientation path for this species (i.e., a Greenland
or Iceland bred Pink-footed Goose oriented in the exact opposite direction
of its usual fall migratory path would eventually encounter Washington).
This species is rare but not unheard of in captivity (G. Toffic, in litt).
Consequently, the possibility the birds were escapees, coupled with the
lack of records west of Pennsylvania for this species or Greenland Greater
White-fronted Goose (A.a. flavirostris) led the Committee to reject this
record based on questions of origin.
The British Columbia committee ruled the same as Washington State, identification
of species is correct, but the origin as uncertain.

The Colorado goose is from 2019 and I cannot find if the Colorado committee has acted.

Add White-cheeked Starling Spodiopsar cineraceus to the Appendix
Here is Pyle:
https://www.birdpop.org/docs/pubs/Pyle_et_al_2018_29th_Report_of_the_ABA_Checklist_Committee.pdf .
There were no photos of the Homer Spit Alaska starling. "There is a sight record (no
photograph) from Homer, Alaska that probably got there by riding aboard a ship and was
observed from May 1-6, 1998 (West 2002)."

OK... ;) Following this other well-known troublemaker, albeit not (yet) on the Internet, Gregory M Mathews https://biodiversitylibrary.org/page/33271351, as well as Charles W Richmond https://www.biodiversitylibrary.org/page/15670410, http://www.zoonomen.net/cit/RI/Genera/L/l00619a.jpg.
(But if this is the reason, it's a bit hard to understand why they did not propose a move to Loriotus right there. What are the questions pending resolution ?)
 
Why they did not propose a move to Loriotus right there? I want to be the first to wish many happy returns of the day to Morton Isler on his 90th birthday on July 21, 2019. What is the hurry Laurent?
 
2019 D-5 Add Pied Wheatear Oenanthe pleschanka to the Main List
Link to Alaska bird checklist committee report with info and picture of Pied Wheatear.

2019 D-4 European Robin add to main list
"No publication is cited by Pyle et al. (2018) about this occurrence, and I am not aware of any"
The Pennsylvania committee has not published a repport on their work since 2012 but there is a webpage of the committee for this bird.

The Pink-footed Goose record was eventually accepted
Thank you.
2019 D-2
Add Thick-billed Warbler Arundinax aedon to the Main List.
In Pyle 2018 and Gibson 2018.
Pittie and Dickinson (2013) concluded that Arundinax has priority.
A 2016 article by Pittie casts doubt on this, maybe?
Jerdon’s Illustrations is remarkable, if not unique, for
combining subscription, offering it through a bookseller, printing
two versions, reprinting some parts, using different printers and
plate sources, and offering plate variants.
Libraries, and bibliophiles, re-bound separate parts primarily
because that was the norm, plus a bound volume also secured
the parts. At this stage the binders invariably discarded original
wrappers along with whatever was printed on them—occasionally
leading to erroneous bibliographic interpretations (Pittie 2009;
Dickinson 2012; Pittie & Dickinson 2013).

The USFWS asks that we maintain a separate US only list.

"...United States Fish and Wildlife Service asks that we maintain a separate US only list."
Thank you Andy. I did not know. My inner Alan Wormington, (deceased Canadian ornithologist who often took umbrage at USA-centric ABA on its blog) started quivering.

No. Arundinax was not in Jerdon's Illustrations but Madras Journal.
