The documentation form by Andrew S. Fix is the only one submitted and forms the basis of this record. Another observer was Craig Harms. | Elimination of similar species: Only species for possible confusion is Common Goldeneye, which was readily separable by the lack of dark lateral breast band in Common Goldeneye. Lack of dark back with linear row of white spots parallel to midline in Common Goldeneye and the overall whiter appearance of the Common Goldeneye. The final spot of the Barrow's is supposedly a cresent [sic] however this was not clearly evident in this bird, as the spot it had was suggestive of a cresent [sic] when compared to the nearby Common Goldeneye. Voice and behavior were not helpful in separation in this case. | The original documentation form event lasted from 11:30:00/12:00:00.

The documentation form by Robert Cecil is the only one submitted and forms the basis of this record. Another observer includes Doug Reeves. | Elimination of similar species: First year Herring much more "contrasty"--see above. Kumlien's Iceland Gull...According to Seabirds (Harrison), 1st year Iceland is more pale, tail uniform gray. Overall body coloration is more like 1st year Glaucous--bird I saw was darker than 1st year Glaucous. [...] The important thing about this uniformity that the accompanying first year Herring Gulls had much contrast, showing whitish head, darker wingtips, dark at the tip of the underwings (sometimes), and most obviously, much darker secondaries, creating a dark trailing edge to the wings. Their general color was a darker chocolatey brown. [...] BILL: Pinkish--noticably [sic] smaller that [sic] Herrings. This is pretty subjective, but at about 2/3 of the way across the river at the dam (maybe one third mile) the bill on a Herring can be easily seen through my scope. [...] A very indistinct darkening (wing, upper surface) of the first two or three primaries. The mark had to be looked for to be seen--on the Herring it was much more evident. [...] At some times, the bird showed secondaries that were slightly darker than the rest of the wing. Slightly should be emphasized--at no time was it even close to the darkness of the secondaries of the first year Herring. [...] There was a very slight and indistinct darkening to the first two or three primaries, but this had to be looked for carefully. I have also seen a number of 1st year Herring Gulls that fit this description, but all have a distinct window at base of primaries. | The original documentation form event occurred at various times during the date range of sightings on the documentation form.

The documentation form by Steve Dinsmore forms the basis of this record. Another documentation form by Ray Cummins was submitted. Another observer includes Randy Strough. | Elimination of similar species: The first-year birds were separated from first-year Iceland Gull by the distinct tail band and the darker primaries and from first-year Herring Gull by head shape, bill size, more uniform body color, and the silvery-white underwing. 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.
