Aged by combination of features: 3rd gen old primaries with mirror on P10 and adult-looking central primaries (like P5), adult-like bill but with often with more black; this combined with immature patterns on coverts (especially greater primary coverts) and often lower tertials or tail. Here also dark centres to secondaries.
