The translucent flight feathers, uniform body color, lack of a "window" on the upperwing, smaller, thinner bill, rounder head, dark smudge around the eye, and smaller size eliminates first-winter Herring Gull. The uniform body color, lack of a dark tail band, and translucent flight feathers eliminates first-winter Lesser Black-backed Gull. | The original documentation form event lasted from 08:00:00/08:05:00.

The adult bird was separated from an adult Iceland Gull by size, bill shape, and more black (still not too much, though) in the wingtips and from an adult Herring Gull by head shape, bill size, and paler wingtips. | The original documentation form event lasted from 10:05:00/10:30:00 and 13:30:00/13:54:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Jim Sinclair and Gordon Brown. | Elimination of similar species: The most similar species would be American Tree and Chipping Sparrows. The combination of white eyering, lack of a breast spot, and pink bill eliminates both of these species. | The original documentation form event lasted from 11:32:00/11:35:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include James J. Dinsmore. | Elimination of similar species: The large size and slightly upturned, bicolored bill identified the bird as a godwit. In flight, the combination of a white rump and black wing linings ruled out other godwit species (Marbled, Black-tailed, and Bar-tailed). | The original documentation form event lasted from 17:52:00/18:20:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include James J. Dinsmore. | Elimination of similar species: The combination of size, dark coloration, and white in the primary shafts eliminated the possibility of a juvenile gull. Despite the great distance and lack of a good view of the wing pattern, I believe the bird was a Pomarine Jaeger. | The original documentation form event lasted from 13:45:00/14:43:00.
