The large size compared to Ring-billed Gulls, heavy build, large, thick bill, prominent white patches on the upper and under surface on the wings, and the presence of a second white "crescent" on the underwing at the base of the primary coverts eliminate both Parasitic and Long-tailed Jaegers. | The original documentation form event lasted from 12:24:00/14:46:00.

The documentation form by Stephen J.

The larger size, longer, more pointed wings, lack of white color in the primaries, longer, larger bill, dark legs and bill, and gray wash on nape (rather than a more distinct half-hood) are sufficient to eliminate Franklin's Gull. | The original documentation form event lasted from 16:05:00/16:30:00 on July 8, 1994 and 06:15:00/06:28:00 on July 9, 1994.

The combination of size, mantle color, and upperwing pattern eliminates all of the hooded gulls except for Franklin's Gull. The larger size, less obvious white eye crescents, larger and longer bill, and extensively dark tips to the underwings eliminated Franklin's Gull. | The original documentation form event lasted from 12:45:00/13:10:00.

The mantle was much too dark for a Herring Gull. Separation from California Gull is much more difficult. Obviously, the mantle color of this bird was much too dark for a California Gull, and the legs were more yellow than the legs of a California Gull. | The original documentation form event lasted from 15:44:00/16:38:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Francis Moore and John Cecil. | Elimination of similar species: The only possible confusion would be with a male Common Goldeneye, thousands of which were available for direct comparison. The bill and head shapes, shape of the white facial spot, and mantle pattern were all diagnostic of an adult male Barrow's Goldeneye. | The original documentation form event lasted from 09:20:00/10:30:00.
