Larus fuscus fuscus probably 3cy, October 31 2009, Ashdod, Israel. Picture Amir Ben Dov. Unringed bird, so no provenance about its origin or exact age. However, there is a clear black line on the bill and the very abraded P10 doesn't show a mirror, two indications it may be in 3cy. Complete moult well underway by late October, with only the outer two primaries old. P6 is fully grown, P7 almost at the length of P6 and P8 is missing. Regarding wear, there is no obvious divide visible in the inner primaries in this image, so there is no indication of moult continuation after arresting moult prior to migration. |
