Heuglini 4cy, March 04 2011, Eilat, Israel. Picture: Amir Ben Dov. 

Showing combination of adult-like primary pattern, with mirrors on both P9 and P10, but also immature features as black in tail, broad bill-band, brown centred greater primary coverts. In general, most reliable combination for ageing such birds as 4cy.
