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.
