Vega Gulls have strong tendency to have heavy streaking through winter. Smaller birds might be female.

This image shows how the range of their molt-timing is wide. The left bird shows a complete set of primaries but the slightly shorter P10. The right bird still shows an old P10. But on average, molts of Vega Gull are later than in Mongolian gull, earlier than in Heuglin's Gull.

The wing shows 6 black pieces and 2 mirrors. This is a typical pattern for Vega Gull, thoug it is variable.

Most Vega Gulls tend to remain winter plumage until April. But whitish-headed birds that are found among a flock frequently trouble us on Vega/Mongolian identification.
