Observation details

^One possible juvenile Lesser Black-backed Gull, with insufficient evidence for ID. Similar in size to, or smaller than, CAGu. Full black bill with white head, dark evenly patterned wings and back with white edged coverts. Did not see the breast or a side view to judge the length of the wingtips. Fuzzy photo of the bird in flight showing dark tail band with pale upper tail coverts, dark outer primaries, paler inner primaries, dark secondaries, all consistent with LBBG. Another 2 dark WEGU-like juvenile birds, one of which had an unusual pale back of head. However, open-wing view shows pale inner webs of primaries like AHGU.
