The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Randy Pinkston, Carol Thompson, and Carl J. Bendorf were submitted later. Other observers include Timothy Dwyer, John Cordell, James Huntington, Cal Knight, Bernie Knight, and Rick Hollis. | Elimination of similar species: First-year Ring-billed Gulls were all in first winter plumage with gray mantle and were much lighter overall. The only other species considered is juvenile Herring Gull. The size is small for Herring Gull. The elongated appearance and short legs fit California Gull. Most young Herrings that I see in early fall have mostly dark bills that are larger than that of this bird. The double inner wing bar and lighter tertial tips fit California Gull. The overall relatively uniform and relatively light brown color without windows in the inner primaries also made this bird look different from Herring Gull. | The original documentation form event lasted from 15:15:00/16:55:00 on October 27, 1990 and from 19:10:00/22:30:00 and 15:00:00/16:00:00 on October 28, 1990.

[...] The whole neck pattern was much different and cleaner looking than the Common Loon. The bill was dark, short, and straight. It was about 1/3 shorter than the bill of the Common Loon and had a stockier appearance. [...] Common Loon eliminated above. Red-throated Loon eliminated by the dark back, neck pattern, and bill size and shape. | The original documentation form event lasted from 11:06:00/11:45:00.

Seeing white on the tail I thought 'Rough-leg'. But this bird had absolutely flat wings as it approached head-on, not with the Rough-legs' 'up-and-out' wing pattern. Three spots of white on an otherwise dark bird - no splotchiness as on a Bald Eagle, no dihedral as in a Turkey Vulture and I knew I was seeing an immature Golden Eagle. | The original documentation form event lasted from 14:10:00/14:12:00.

Upland Sandpiper would have been larger and not had the buffy color. | The original documentation form event lasted from 16:35:00/16:45:00.

The documentation form by Thomas H. Kent forms the basis of this record. Other documentation forms by Ann Johnson, Jim Fuller, Carol Thompson, and Randy Pinkston were submitted. Other observers include Jane Huntington, James Huntington, Jim Sandrock, John Cordell, John Daniel, Mary Noble, Ken Lowder, and Tim Schantz. | Elimination of similar species: The only other species worthy of consideration is Pectoral Sandpiper. The most distinctive feature is the plain, cinnamon-buff breast without bib line or streaking centrally. The soft breast color shaded off evenly to the lower belly and throat. Some pectorals had very week [sic] breast markings, but on close inspection all had streaks and a sharp bib line. The solid rusty cap differed from any pectorals; some pectorals appeared a bit rusty on the cap, but some streaking was seen on such individuals. The eye line appeared white, and it dropped and widened posteriorly. Some pectorals had light eye lines but they were off-white, less distinct, and straighter. The juvenile feathers of the upper parts were edged with rufous; this was especially prominent on the tertials. Some pectorals appeared to have rusty edging on the tertials, but this was dependent on lighting and at least one rufous appearing pectoral had the color more in the center of the feathers with grayer edging. The gray smudging on the undertail coverts I saw once and only had a glance at a nearby pectoral for comparison, so I am not very confident of this mark. | The original documentation form event lasted from 09:20:00/09:25:00, 09:55:00/10:00:00, and intermittently 16:15:00/17:00:00.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Dick Tetrault. | Elimination of similar species: The size and shape in comparison with Baird's Sandpiper establish this bird as a peep. The black legs, gray color, and lack of bib exclude Least Sandpiper (several of which were seen earlier). The distinction from Semipalmated Sandpiper is based on the bill and apparent molt to basic plumage. Five minutes earlier I had seen two Semipalmated Sandpipers running on the other side of the area; they had short straight bills and had all feathers of the upper parts edged with buff (juvenile plumage). I had seen a number of Semipalmated Sandpipers with longer and slightly drooped bills this fall, but none approached the length, thinness, and droop seen on the current bird. According to Kenn Kaufman's Advanced Birding, Semipalmated Sandpipers wear their juvenile plumage until they reach wintering grounds, and juvenile Western Sandpipers gradually molt from juvenile to basic plumage from August to October with some retaining rusty scapulars. I assume, based on date, that this bird was probably a first-year bird, and that it had either completely molted to basic plumage or had some rusty scapulars that I did not see. I did not consider any of the Eurasian stints, which would be exceeding unlikely and have bills more like a semipalmated or have yellow legs. | The original documentation form event lasted from 10:15:00/10:20:00.

Eye coverts were not immediately noticable [sic] due to white cheek area. 2. Longer legs, more upright posture, and generally a very long, slender bird. 3. In flight, the bird had long slender wings with completely dark primaries; no white dividing the tips of the outer primaries from the rest of wing, and no white tips to outer primaries. Underside of primaries as described above. 4. Bill was long, curved and slightly swollen and hooked at tip. | The original documentation form event lasted from around 07:35:00/07:36:00, 08:45:00, 12:15:00, and 18:30:00.

The article by Stephen J. Dinsmore forms the basis of this record. | Elimination of similar species: [...]The bird was similar in size to the largest Ring-billed Gulls, but slightly larger than others. I approached closer and noted that, when compared to a Ring-billed Gull, the bird had duller yellow legs, a stouter bill with black and red spots near the tip of the lower mandible, and a darker gray mantle. [...] The bird was slightly larger than most of the Ring-billed Gulls, although one or two of the biggest Ring-billed Gulls were as large as the bird I was studying. Proportionately, the bird was heavier and larger-headed than a Ring-billed Gull. [...] I estimated the mantle color to be about midway between those of Ring-billed Gull and a Lesser Black-backed Gull. [...] The bill was heavier than the bill of a Ring-billed Gull and had a distinct gonys. The legs were pale gray-green, unlike the bright yellow legs of a Ring-billed Gull. Leg length appeared similar to a Ring-billed Gull. | The original documentation form event lasted from 07:45:00/09:27:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Scott Rolfes. | Elimination of similar species: The color and wing crescent eliminates all larids except skuas and Pomarine and Long-tailed jaegers. Skuas are easily eliminated by their larger size, heavier bill, and more prominent white patches on the wings. Long-tailed Jaeger is eliminated by the presence of a white crescent on the upper surface of the wing. Pomarine Jaeger can be eliminated by its larger, heavier body size, more prominent white crescent on the wing, presence of white greater underprimary coverts, larger-headed appearance, heavier bill, and general lack of rufous color on the body. | The original documentation form event lasted from 16:22:00/16:51:00.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Pam Allen, Jim Dinsmore (2x), Mark Proescholdt, Beth Proescholdt, and Tim Schantz were submitted later. Other observers include Jim Fuller, Ann Johnson, Reid Allen, and unidentified other observers. | Elimination of similar species: The fairly large size and gray and white plumage eliminates all shorebirds except Sanderling and winter-plumaged Dunlin. Sanderling is eliminated by smaller size and different bill shape. Winter-plumaged Dunlin is eliminated by different bill shape, slightly smaller size, and different tail pattern. | The original documentation form event lasted from 17:20:00/18:48:00.
