Stress features that separate it from similar species):

Looked massive, about 10-20% larger than the neighboring Herring Gulls, and with relatively short wing, particularly in comparison to the Lesser Black-backed Gull.Bright bubble-gum pink bill with distinct black tip, about ľ of tip was black.Legs appeared relatively pink even next to immature and adult Herring Gulls.Eye looked dark (but not certain), and small/beady relative to head size.All creamy white except for fine light brown vermiculations on back, barely visible at distance.Apparently not molting.
