3cy heuglini, with left P1-P2 and P6-P10 2nd-gen., but P3-P5 ad-type already. Right wing: P1,P2, P4, P6, P8-P10 2nd gen. like; and P3, P5, P7 adult-like (probably 3rd gen).
Conmplete tail probably 3rd gen. Secondaries in left wing with few "2nd gen type" feathers (extensive dark centres) but most secondaries are 3rd gen type feathers, which are more adult-like but may have some reduced dark in the centres. Upper-parts already adult-like grey.
