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.

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 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.

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.

Other observers include Ken Lowder, Jim Scheib, Bud Goode, Cal Knight, Bernie Knight, and Beth Brown. | Elimination of similar species: The head posture resembled a cormorant, but the bill, overall coloration, and behavior quickly excluded that possibility. The size and bill led me to an immediate identification. I was puzzled about the plumage. I expected to see a juvenile or basic-plumaged bird, but the distribution of dark coloration was that of alternate plumage. I assume that the red/black throat, lines of neck, and gray tones had faded to give one rather uniform color. The drab light may have contributed some to the failure to see color differences, but the last observation was relatively close and the texture of the feathers could be seen. | The original documentation form event lasted from 07:45:00-08:30:00 and 12:20:00-12:45:00.

This bird also showed a more rounded head and definite black/white contrast which was lacking in the Red-throated Loon I had observed six days earlier. Common Loon was eliminated by combination of size, smaller bill, distinct line separating white and black feathers, and ultimately by the chinstrap. | The original documentation form event lasted from 12:10:00/12:30:00.

Other observers include Babs Padelford, BJ Rose, Ross Silcock, and Tim Schantz. | Elimination of similar species: Cormorants could be eliminated by bill shape, among other characteristics. The bird had some similarities to a Western Grebe, but the grebe would hold its head parallel to the water, has a longer neck, and does not show the contrast between head/nape and back. Common Loon was eliminated by posture, size and shape of bill, contrast of lighter head and darker back, and more diffuse separation of upper and underparts. Pacific Loon was eliminated by the grayer underparts, diffuse separation of upper and underparts, posture, and sharp upward angle on lower mandible. | The original documentation form event lasted from 11:50:00/12:15:00.

[...] I first saw this bird flying, and the underwing was translucent throughout the primaries to the end of the wing (Herring Gull had dark outer primaries, although most also had a lighter window type area medial to this dark area). The bird was about the same size or a little smaller than the Herrings. The upperwing in flight was much lighter in the primaries than the first winter herrings. [...] It had a more rounded head than the herrings. [...] It's color was more uniform than the herrings and also lighter- a brownish color. There was a dark smudge around the eye. The feather edging (whitish) provided more contrast with the brown on the back than in the herrings, and the folded tail was brownish, not black. When in flight the tail band was brownish not blackish like the herrings. | The original documentation form event lasted from 13:15:00/13:45:00.

The documentation form by Brian Blevins is the only one submitted and forms the basis of this record. Another observer was Lewis Blevins. | Elimination of similar species: Summer, Scarlet, Western Tanager. Scarlet Tanager was eliminated by the lack of dark wing and the orange-green instead of yellow-green. Western Tanager was eliminated by the lack of wing bars. Summer Tanager: this was the closest of the three especially considering the cooperi form found in the southwest. The large bill in common to both species if we consider the cooper form of the summer, however, the color of the mandible overall more dark than light lends the pull towards hepatic. The dark, brown orange-green also pulled me over to the hepatics in respect to the ones I have observed in Arizona. Call note also differs. | The original documentation form event lasted from 13:15:00/14:20:00.

The documentation form by Jim and Karole Fuller is the only one submitted and forms the basis of this record. | Elimination of similar species: All other adult dark mantled gulls have pink legs, except the Yellow-footed gull which is seen at the Salton Sea, and extreme southwest California. That bird has never been seen away from that area, and should be noticeably larger than a Lesser black backed gull. The European race of the Herring gull has yellow legs, and one has been seen on the east coast the past two winters. That bird should be larger, and does not have a dark mantle. | The original documentation form event lasted from 14:03:00/14:27:00.

The documentation form by Tim Schantz is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller, Ann Johnson, Thomas H. Kent, Diane Porter, Jim Sinclair, Stephen Dinsmore, James Dinsmore, Beth Proescholdt, and Mark Proescholdt were submitted later. Other observers include Dawn DeVore, Dick Tetrault, Jim Scheib, Beth Brown, Michael Porter, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: [...] Iowa Birds mentions that there is a problem separating Iceland with Thayers. If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.
