Choshi harbour, Chiba, Japan | 5 March 2020
A subadult (4CY?) argentatus-grey herring-like gull with little white and little black on the primaries.
For now I think the last of my gulls in Choshi harbour. I have been reading up on the subject, looking at a few 1000 photos over the last weeks and of course...i'm drifting further from firm knowledge than I wished for...but that is part of the learning process of course.
But it also means that I don't dare give a real suggestion anymore.
What would you say this is...
Vega is the standard for the area, Mongolian Gull, Taimyr Gull, Glaucous Gull, Thayer's Gull, Glaucous-winged Gull and American Herring Gull are the large white gulls of the area.
All of them were seen in the same period. I have been thinking it could also be another Thayer's.
I have been checking several (near)brilliant gull-sites, www.gull-research.org of course, but also

anyone?
cheers,
