   По поводу этой молодой чайки и по той темной чайки из Жанаозеня:
   
   Hi Qanatbek,
   
   The second calendar-year bird is Larus fuscus fuscus, based on the combination of the slim elongated appearance (fi very long wings), dark overall plumage, slender bill and rather dark new scapulars.
   
   The very dark older bird (probably third calendar-year also is Larus fuscus fuscus.
   
   This confirm this taxon being a rare but regular passage migrant (mainly) through the Caspian region, although it might be overlooked in the large numbers of heuglini and barabensis. On 28 June, a second calendar-year Finnish bird,has been found dead 40km southeast of Ebeyti, Aktobe province.
   
   All the best,
   
   Arend
