Heuglini adult, October 12 2011, Ashdod, Israel. Picture: Amir Ben Dov.

Heuglini showing no active moult: tip of P4 (with black on outer-web and P5 look perfectly new), P6 has the tip slightly worn (but this feather is not protected by the tertials). Outer primaries look neat as well. Arrested moult or early completion? P10 and P9 with mirrors.
