Vagrancy of Siberian vs Tibetan Sand Plovers - anyone knows which? (1 Viewer)

[njlarsen]

When checking our opus pages for this split, there are some places where an observation has been made of the pre-split Lesser Sand Plover. Can anyone help with figuring out which form was seen?
First location is in Turkey:

Goksu Delta - BirdForum Opus

www.birdforum.net

Next one in Poland

Gdansk Bay - BirdForum Opus

www.birdforum.net

Third one Australia, and for this one, the ebird hotspot information includes neither:

Eyre Bird Observatory - BirdForum Opus

thanks

Poland: Some think Tibetan (2 eBird checklists), others don't know/care (2 eBird checklists). Said to be atrifrons in the paper below:

Turkey:
not on eBird; not on Tarsiger;

A sight record from the Goksu Delta on 21 April 1980 (Bezzel 1986) does not convincingly eliminate Greater Sand Plover, while another there on 24 August 1989 which was originally accepted (Kirwan & Martins 1994) must now be rejected as the bird shows the typical structure of columbinus (E. Hirschfeld in litt. 1996). Additional sight records from the 1980s and early 1990s, at least one of which was photographed, are all either clearly columbinus or lack substantiation, as does the comment by Turan (1990) that the species is a rare visitor in the east and south-east.

(from 1999 (five years between 1999 and the first record of Lesser Sand Plover on Tarsiger from 2004): https://www.researchgate.net/profil...04af3d/A-checklist-of-the-birds-of-Turkey.pdf)

Australia:
not on eBird;

[Charadrius mongolus mongolus Pallas, 1776 Mongolian Sand Plover
Unconfirmed reports from Eyre (Congreve 1982; P. Congreve 1983, West. Aust. Bd. Notes No. 26).]

(but it's from 1987, so more recent records possible?: https://museum.wa.gov.au/sites/default/files/1. Storr_4.pdf)

Siberian Sand Plover is the clear and obvious default in Australia https://ebird.org/species/lessap2?siteLanguage=en_GB#:~:text=Medium%2Dsized%20plover%20with%20a,variable%20white%20forehead%20and%20eyebrow.

Correct, but there is also examples of vagrancy of Tibetan to NW Australia.

The paper from Poland is pretty clear on the bird from 2005-6. They also mention an older observation in 1977 (while our Opus page mentions 1969) - any knowledge of split-species of those?

Thanks. I added Tibetan for the list of vagrants at Broome

[njlarsen]

Thanks. I am not sure if you are aware, but you can embed the video into the birdforum gallery too.

Could you also post it in the Gallery so that our articles in Opus could link to it?

Our Opus articles can only pick them out when they're in the Gallery, and they'll live on there after this thread fades into oblivion :

And please keep them coming--thanks!

I think you also posted a video about Malaysian stint species somewhere that you haven't uploaded to the Gallery yet.

EDIT: Love those ones entering from the left.

All birdwatchers interested in waders from the east should follow the great work Dave Bakewell posts on YouTube. He is is mainly based in Sarawak and his videos are something many have us learned from. Give the Little Whimbrel and the stunning Red-necked Stints a view….Cheers Dave 👏

 

[njlarsen]

Sorry, given that I don’t know your name, I assumed these were your own. Is Dave a member? Or could you talk him into becoming one?
Niels

 

[01101001]

Yes, sorry as well. I did give it some thought, but in the end... Anyway, I messed it up (a bit). At least, we now have a wonderful set of videos to watch, at hand.

BTW, it's only about the Gallery (oh well): they're perfectly fine in this thread and should definitely stay here for others to behold.
