Heuglin's Gull L heuglini
1-4: © Visa Rauste, 14-06-02. Syktyvkar, Russia.
Another large and presumably male bird. Like the previous one it shows two types of non-juvenile wing coverts and, more importantly, and is one of those 2cy Heuglin's Gulls showing second generation primaries. The moult sequence, however, is unusual, as in the right wing it has retained the juvenile P3 and in the left wing P3-4. P1-2 are pale grey with a black marking on the outer web near the tip. The rectrices are worn second generation feathers.
