Ageing in autumn is trickier Valery and would normally require close examination in the hand to check 1) structure of PC, 2) presence of a moult limit in MC and GC (not always obvious in latter) and 3) colour of inside of bill (applies early autumn).

Since the OP does not allow close scrutiny of the wing coverts it cannot be safely aged.

Thank you Graham, that's good then, we keep it unaged.
 
I don't know this detail. On these photos, we can see the colour inside the bill. Same bird. Can it be enough ?
Still tricky Valery because you should examine the underside of the upper mandible (see link provided) which is not visible in any of the images. However, the inside edge of the gape is (still) yellow vs black in adult (1st image) which should confirm age as 1st-w.
