Heuglin's Gull L heuglini
1-4: © Visa Rauste, 14-06-02. Syktyvkar, Russia.
A bird with boldly marked second generation scapulars and wing coverts, very different from birds like this plain individual or this even plainer individual. Both the secondaries and rectrices are a mix of juvenile and second generation feathers. Unlike most of the previous birds, the primaries of this individual are quite worn.
