Great Black-backed Gull (Larus marinus) JH092 1cy, November 06-10 2010, Westkapelle, The Netherlands. Picture Corstiaan Beeke & Ies Meulmeester.

Bird ringed as pullus on 24 June 2010 at Ytre Mannevaer, Mandal, Vest-Agder (Norway).

Most scapulars are renewed to second generation feathers, except the lowest row (LLS). In flight note the dark v-marking / anchor pattern on the primary tips of p1-p4. And the pale spots along the edges of the dark shafts near the primary tips, in the left wing on both sides of the inner primaries and in the right wing especially very clear on the inner webs of p1-p5. P10 is slightly shorter than p9.
