Larus armenicus adults, 15 October 2010, Maagan Michael, Israel. Picture: Amir Ben Dov. Adult armenicus at the beach. Bird with one single old primary in the wing: P10 still old. Common moult stage is P6 fully grown or even P7 fully grown (at least P7>P6), with P10 still old. Next common moult stage in slightly more advanced birds will be P7 fully grown, with no old primaries left. Here: two images, P10 still old. P6 fully grown, P7>P5. Active moult in secondaries and rectrices (R6 still old). Bottom image nicely shows the far right wing, with a common pattern of moult sequence: P7 is slightly shorter than P6 (but can look so due to the angle of observation) and P1`0 still old. S1 is fully grown and the tip of S2 is obvious. Then there is the ordinary gap in the central secondaries, with several old retained feathers more inwards. |
