Hello! I have some doubts about these two gulls. The first picture is from Feb 2019, I know some YLGs can have reduced black on p5, only on the outher web, but still not 100% sure about this bird. On the second picture, the gull is from Jan 2022, with striated head, pale iris, large white mirror on p10, yellowish legs, but also, I'm not sure what can be said because of the poor quality of the photos.
