Appears to be reoccurring adult individual of previous years. This bird shares same single mirror primary pattern, exact mantle shade and winter head streaking as the 2017 & 2019 gull. Dusky yellow peppered eyes, pinkish purple orbital, heavy looking gull compared to surrounding herrings, slaty mantle with large broad crescent, yellow bill with prominent red spot, deep purple/pink legs. P10 almost fully replaced, showing large mirror with small band, a few central secondary feathers missing. Seen and documented well.
