Next one from left a small dark one, probably a Baltic?:
A big one, probably Heuglin's:
A little one, Armenian?:

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:
