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 Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Eugene Armstrong, Eloise Armstrong, and Mark Proescholdt were submitted later. | Elimination of similar species: The body shape, posture, and black-and-white coloration identified the bird as loon. Although some Common Loons may be quite small. I think this bird was too small for even a very small Common Loon. Otherwise, the slender, upturned bill, the head posture, the contrast between the back and the neck, and the gray neck and white throat eliminated Pacific and Common Loons. | The original documentation form event lasted from 13:46:00/15:43:00.

The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] I ruled out other gulls, especially A [sic] young Herring Gull (1st yr) because of the location of the white (belly & wings) as well as the deep rowing flight. In addition, I had the opportunity to observe the Pomarine Jaegers earlier this fall at the same location and the markings were similar, except this bird was darker with a white belly. | The original documentation form event lasted from 14:40:00/14:40:25.
