The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: The primary identification was done through the size and shape of the head. Other similar gulls do not share this "dove head." The bird was confirmed by the silvery underwings and very little dark coloring on the upper side of the primaries, characteristics not shared by similarly gray-mantled gulls. | The original documentation form event lasted from 08:40:00/08:40:00.
