Scapulars replaced. Wing-coverts and tertials still juvenile.
Complete moult just started, in the most common sequence in bthe wing-coverts: inner mc have been shed. Probbaly, the upper tertials and inner gc will soon follow. This all moult simultaneous with the inner primaries.

Late August, the complete moult is nearly ended, with P9 alreday fully grown. The gap in the central greater wing-coverts has closed; time for the partial autumn moult which normally includes upper tertials, inner gc and many mc and llc. At this moment: the median coverts have been dropped again, for the second time this year, and new 3rd gen feather will appear (which may well look either 2nd gen-like, or more adult-like plain grey; especially the last replaced feathers in the partial autumn moult, by early October).
