And Lou Bertalan's scoring (from Facebook):
Extent of scapular moult
1 a small number (less than 1/3) of first-generation feathers remaining
1 white edges with delicate notches or vermiculation; or dark brown centre with white tip to 1/3 of length (i.e. white restricted to tip or distal third)
1 Slim, slight gonydeal angle (ratio 2.87, so actually >2,8 but there is a slight gonys angle visible)
1 Moderately long
0,5 - there is a very slight bulge visible but note especially the flat belly in front of it!
1 moderately long (ratio 0.5
Moult: greater coverts
5 no moult
Moult: median coverts
4 one or two feathers moulted
3 all old
Darkness of head and body
1 reduced grey wash or streaking (confined to flanks and/or single streaks around nape)
First-generation tertial pattern
1 fine pale fringe around distal portion (like classic michahellis), possibly also with some vermiculations
Second-generation scapular pattern
2 strong, contrasting shaft-streaks, anchors and/or dark central diamonds, but these more patterned feathers are less than 1/2 of all; ground colour creamy or silvery-grey, possibly with some grey feathers mixed in.
so this makes a score of 21,5 which is still within cachinnans, close to the border to hybrids. but it also illustrates some weakness of this scoring system. covert moult weighs too much, imo (5 points for no replaced GC!), there is no criteria for rectrices pattern which personally i give a lot of weight, and it simplifies matters of 2nd gen. scpaular pattern: there are certain types of scapular patterns and each one should be scritinized separately.
what i'd still discuss in this bird is: head jizz (mentioned as not good for caspian gulls) - yes, could sit on a weak female YLG too, especially with the slight eye smudge, but caspians can show even more dark striation around eye than this. scapular pattern is of the shaggy type with one central transversal mark and only a weak thin (or absent) subterminal band. this is a common type in caspian, can appear in other taxons too but usually more bold (double anchor in YLG, bold subterminal bar giving a scaly look in HG), which i think is often underestimated because one likes to have the nice diamond shapes or just shaft streaks as typical cachinnans pattern - but this distorts reality since at least half of all 1st winter caspians don't show this kind of expected pattern but the one more similar with the other taxons. tail in this bird is very good for cachinnans, inner wings shows the nice venetian blind with p2-4 showing pale lozenges etc...
