In my opinion this Penduline Tit is defenitly not Black-headed, which is much darker both in upper- and underparts. But this bird don't look like to Common Penduline Tit (Remiz pendilunus caspicus) also due to paler colour. It's uncommon but bird most like to Remis coronatus, breeding in SE Kazakhstan. Unfortunately face pattern is in shadow in both photos, but it looks realy all black.

I move this serie to unidentified bird for discussion.
