Typical spring 3cy:
- 2nd gen primaries, without a mirror on P10,
- 4 coloured bill, with just a hint of red, broad bill-band and white tip,
- pale iris,
- at least several tail-feathers with broad band,
- 2nd gen like outer greater coverts.

Note S4 in left wing more mature, as if replaced again in partial autumn moult.
