Gull ssp, June 10 2010, Ilinka, Cheboksarskye Vdhr (Reservoir), Chuvash Republic, Russia (56°11'00.0"N 46°47'00.0"E). Picture: Grzegorz Neubauer.
Probably younger adult (or sub-adult) bird, alarming and flying over the colony. Aged by small primary tips and dark markings on underwing coverts. This is supported by much black and less white in the wingtip.
Phenotypics:
P10 medium mirror separated from white tip by subterminal band, long short pale tongue on P10, not ending square.
P9 no mirror.
P5 with full subterminal band.
P4 with faint but full subterminal band. Black spot on outerweb of P3.
Moult: P1 growing, P2 missing, P3-P10 old.
P5 missing in left wing.
From this angle the iris looks pale, clouded. Orbital ring seems to be red. Bill seems to have no red on upper mandible.
