In upper two images note residual dark marks in tertials and old (not yet moulted) outer primaries and primary coverts. In flight shot note newly acquired fresh grey inner primaries contrasting with old, retained outer primaries. Close views and some photos revealed very small black subterminal mark in several tail-feathers. In late June a single tail feather displayed a more obvious black subterminal band but by the time of the flight photo above (July 3rd) this had been dropped. Although only early July, appearance equates with a 3cy moulting from 2S into 3W plumage.
