Heuglini 2cy, April 01 2011, Ashdod, Israel. Picture: Amir Ben Dov. 

Juvenile wing-coverts abraded, but several 2nd gen feathers still fresh. Inner lower lesser and median coverts old 2nd gen. Unfortunately inner primaries not visible, as the fresh coverts may also indicate complete moult in southern taxa (of which the commonly present armenicus which starts moult by early April in 2cy).
