I get tired of this nonsensical race to the bottom in assessing people's capacity to not be confused by similarity. Stability in names is a thousand times more important than uniformity. And it's still Bearded Tit.

Actually, you'd be surprised. On wiki commons, I've found (and dealt with, so they're not there any more) several Erithacus rubecula pics put in Category:Turdus migratorius, and vice-versa. And numerous other examples with other cases of incorrect vernacular name sorting. You might know enough not to be confused, but an awful lot of people don't, sadly.

I wouldn't be surprised, but I also wouldn't be surprised if half the errors are due to non-birders (a different group than those we are talking about here, who are capable of more and grosser errors than this) and use of insufficient of the name. Only Erithacus rubecula is a Robin: Turdus migratorius is an American Robin and requires the use of its whole name.

You can't legislate for ignorance, so it's not a consideration in creation of names.

The more eastern, nominate subspecies is much larger, and the plumage variation includes a dark morph, which is more frequent in the eastern part of its range (Ferguson-Lees and Christie 2001).

not much new hear, other than confirmation that the Comb Duck split passed, and hummingbirds did get reorganized.

Good catch!
The Key says “
L. Cirtensis of Cirta, Numidia (= Constantine, Algeria)”

B. rufinus fatherland is Das obere nubien etc basically Sudan along the Niles ad Ethiopia.
https://www.biodiversitylibrary.org/...e/257/mode/1up .
Here is Vaillant 1850 F. cirtensis:
https://www.biodiversitylibrary.org/...e/473/mode/1up . only the drawing is his the text is from Loche and from 1867.
Info: https://www.biodiversitylibrary.org/...e/405/mode/1up .
Vaillant is the son of the other one. He was a French soldier in Algeria in the 1840’s. The French army must have killed a lot of raptors in that campaign:
https://www.birdforum.net/showthread.php?t=386386 .
Are Sudan birds still considered B. rufinus? Even in America Algeria is west of Ethiopia.

IOC10.1 states for cirtensis: Mauritania to Egypt and the Arabian Peninsula.

Jowers et al 2019 focused on the taxa within the Buzzard superspecies via a battery of DNA techniques. Amongst their conclusions is that taxon cirtensis is best considered an allospecies of Common Buzzard (comprising buteo, vulpinus), although it has two lines of ancestry, the other being Long-legged Buzzard (rufinus).

Just to clarify, B. (rufinus / buteo) cirtensis is strictly resident, breeding in Africa north of the Sahara; B. r. rufinus is partially migrant, breeding SE Europe eastwards; the type locality of rufinus in Sudan / Ethiopia is in the wintering grounds, not the breeding area

It is not strictly resident as there are hybrids between cirtensis and Iberian buteo in southern Spain. The Strait of Gibraltar is apparently not an obstacle for the North African birds.

2020-D-5: Add Tahiti Petrel Pseudobulweria rostrata to the US list
A bird was also well-photographed off Hatteras, North Carolina, on 29 May 2018. I presume that
it has been accepted by the state committee, but I am unaware of a publication on it.
Bird Records Committee reports

Swick, Nate, et al.. 2019. 2018 Annual Report of the North Carolina Bird Records Committee. Chat 83:17–21
Tahiti Petrel (Pseudobulweria rostrata): Accepted. (18-15). Easily one of the most incredible bird sightings in North Carolina's ornithological history, an adult Tahiti Petrel was seen from a Seabirding pelagic in the Gulf Stream out of Hatteras (Dare) 29 May 2018. The NCBRC received and unanimously accepted a written description from Ed Corey with photos from Peter Flood and Kate Sutherland. This record represents the first record of this species for the Atlantic Ocean, let alone North Carolina, and by virtue of submitted photographs it is placed on the Definitive List.

Online here (currently accessible only by Carlina Bird Club members). The latest issue of Chat (84(1): 10–13, Winter 2020) includes "A Tahiti Petrel (Pseudobulweria rostrata) off Hatteras, North Carolina USA", a write-up of this extraordinary record by Peter Flood, Kate Sutherland and Brian Patteson. The cover includes a photo of the Tahiti Petrel offshore from Hatteras on 29 May 2018 by Peter Flood.

Here is the 17th Conn. state bird record report.

And a funny Blog post about the Rhode Island goose that compares the two U.S. geese.

2020-D-3: Add Eurasian Oystercatcher Haematopus ostralegus to the US list
This is a situation which makes it unfortunate that the AOS has abandoned subspecies:
https://americanornithology.org/publ...can-checklist/ .
Here they refer people to other checklists for updated subspecies. The 1995 ABA report accepting Euro Oystercatchers to ABA area does not cite a subspecies.
https://www.aba.org/wp-content/uploa...03/ccr1995.pdf .
But the 1957 5th AOU Checklist used H. o. occidentalis for the subspecies of the Greenland specimens.
http://www.zoonomen.net/cit/RI/SP/Habi/habi00095a.jpg . Supposedly from the Orkneys.
Not sure why they did not cite H. o. m.
http://www.zoonomen.net/cit/RI/SP/Habi/habi00094a.jpg . Iceland.
The HBW do not use either subspecies so the Greenland birds are H. ostralegus ostralegus.
The Alaska Committee report diagnosed their oystercatcher as H. o. oscularis Swinhoe China.
http://www.universityofalaskamuseumb...0Committee.pdf .
EBird lists Russian and Kamchatka and Iceland oystercatcher groups??
