Last wintering Gulls

Five interesting birds together, 18 Mar.

To the left side a 4 cal year Caspian:
Next one from left a small dark one, probably a Baltic?:
A big one, probably Heuglin's:
A little one, Armenian?:
And the 15 cal year one male Baltic again:
Differences in length of legs:
Three birds on flight: One with heavy primary moult in both winds:
Another (michahellis?) on heavy primary moult:
And a whitish first winter-2nd summer bird, just a michahellis?:
A 2nd-winter/3rd summer? fuscus type bird, probably intermedius, 17 Mar:
Most Gulls now on move...

Heuglin's or Steppe?

The individual above, seen on Irakleion harbour on Mar 8 looks like 1st winter to 2nd summer bird. Best choice is heuglini ?
The next 4 photos is most probably another 1st winter-2nd summer bird on Mar 10, pretty small in size, with an interesting early body moult (if age is accurate), with quite long bill, giving a good possibility for being a "barabensis":
Body colour not as dark as the previous bird - just different light conditions.
