The combination of slightly smaller size, longer wings, whiter rump, more speckled mantle, contrast between the darker mantle and lighter head, and darker upperwings lacking a pale "window" eliminated Herring Gull in first-basic plumage. | The original documentation form event lasted from 15:22:00/15:40:00.

The combination of size, the large bill, large amount of white on the upperwing, white color in the underpirimary coverts, and blunt-tipped central rectrices rule out juvenile Long-tailed and Parasitic jaegers. | The original documentation form event lasted from 13:12:00/13:55:00 on November 16, 1996 and 15:40:00/16:30:00 on November 27, 1996.

The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. | Elimination of similar species: The amount of black and white in the outer primary tips (both upper and underwing) is much less than would be expected in Ring-billed or Herring. Ring-billed is smaller with a dark ring on bill of adult. Although a few Herrings have somewhat bright pink legs, most are a dull pink. An Iceland adult should have a lighter mantle and upperwing, and less gray (not black) on the outer primary tips. | The original documentation form event lasted from 13:50:00/14:15:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by James J. Dinsmore was submitted later. | Elimination of similar species: The dark coloration, gull-like shape, and white color in the primary shafts identified both birds as jaegers. Initially, I thought the bird I saw on the 10th was a Parasitic, mainly because of the size and seemingly bright, rust-colored underparts. However, better viewing conditions later showed that the underparts were instead a pale brown color and lacked any hint of rusty color. Long-tailed Jaeger was easily eliminated by size, shape of the central rectrices, and the greater amount of white in the wing. Parasitic Jaeger was more difficult to rule out. The combination of size, wing shape, amount of white in the wing, shape of the central rectrices, and bill size was used to rule out juvenile Parasitic Jaeger. | The original documentation form event lasted from 09:35:00/12:33:00 on November 10, 1996 and 10:55:00/16:05:00 on November 11, 1996.

Kent, Jim Fuller, and Chris Edwards were submitted later. | Elimination of similar species: The apparent size differential, bill size and clean line to the neck eliminated Common and Yellow-billed Loon. Red-throated is approximately the same size but the bill appears upturned because of the angular shape of the lower edge. Red-throated also has a head lighter than the body. A chinstrap would not be seen on any other species. Grebes were eliminated by thickness of neck and general jizz. | The original documentation form event lasted from 13:30:00/13:40:00.
