A typical Vega Gull.
Same individuals as above.
Same individuals as above. Note the striped marginal coverts and lack of dark greater covert bar. The tail band looks apparently broader when the tail is closed.
Same individuals as above. Underwings are rather unifrom in this individual.
A raugh-marked individual.
A pale, advanced individual. The paleness recalls somewhat mongolicus, but the rather uniform textures and overall impression looked suitable to be Vega Gull, in the field.
A relatively browner, mottled juvenile.
The underwings are rather dark with vermiculations.
