Heuglini 2cy, April 30 2010, Eilat, Israel. Picture: Amir Ben Dov. 

Heuglini can show a variety of moult scores when we see them as 2cy in N Europe. Irregular moult in secondaries and primaries is hardly an exception. This bird is replacing P2 in both wings. Note the active moult in wing-coverts by April, which make such bird look relatively fresh when they turn up in N Europe in June.
