Larus armenicus 4cy, 15 October 2010, Ashdod, Israel. Picture: Amir Ben Dov. When the outer primaries have been dropped, ageing can be difficult. Fortunately, there are still a few old retained secondaries visible in this individual. These often are the last feathers to be dropped in the complete moult, and they may give a clue to age. Here, these inner secondaries (often S16-S18) are quite adult-like, with a grey base and broad tip (although very worn), but clearly not a large dark centre as would be expected in old 2g secondaries. Of course it still is only a hint to age, as the secondaries are sometimes replaced in a winter moult by some species (especially fuscus, intermedius and heuglini), and it has to be seen if the same happens in armenicus (a michahellis related species, hence less likely). Yellow legs, limited to no black on the primary coverts, broad tips to the primaries and no extensive black in the tail support the idea of 4cy bird. Outer primaries still growing. |
