The documentation form by Matthew Kenne is the only one submitted and forms the basis of this record. Other observers include Lee Schoenewe. | Elimination of similar species: The bird was standing on Manhattan Point with several Herring Gulls of various ages and many more Ring-billed Gulls, facing quarter-on towards Lee Schoenewe and I. It was a dark 1st year gull, similar to, but slightly smaller than, other 1st year Herring Gulls present. It had an all black bill that was smaller than the other Herrings. [...] Lee and I waited for about 10 minutes for the bird to turn to the side, showing us blackish wingtips and dark tertials, eliminating the Thayer's Gull possbility we had been considering. The wing tips extended farther beyond the body than on the Herring Gulls. [...] There was no pale 'window' in the inner primaries as in a Herring Gull. | The original documentation form event occurred in the early afternoon for approximately 10 minutes.
