The documentation form by Matthew Kenne is the only one submitted and forms the basis of this record. | Elimination of similar species: The lack of facial pattern and white throat and chest rule out peregrine, as the bird was flying almost directly into the sun (perpendicular to me). It wasn't as pale or brown as a prairie, and with shadow and distance there wasn't any dark/light pattern to the underwing. It wasn't black as a crow + the shape was wrong. Eagles were patterned and obviously larger. | The original documentation form event occurred around 13:10:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Another observer was Brian Warson. | Elimination of similar species: The bird was clearly an alcid. The small size rules out the murres, Razorbill, and guillemots (see earlier discussion). The long, thin bill eliminates Dovekie, Ancient Murrelet, and all of the auklets. The bill shape, dark cap that included the eye, and presence of two white patches on each side eliminates all other murrelets, especially Kittlitz's. | The original documentation form event lasted from 15:15:00/15:24:00.

The documentation form by Jim Bangma is the earliest and the one that forms the basis of this record. Another documentation form by Ann Johnson was submitted later. | Elimination of similar species: Double-crested is smaller, with a much thinner neck. There is a noticeable transition from the thin neck to the larger head. In this bird, there was no noticeable widening from the neck to the head. Additionally, Double-crested has a proportionally much smaller and weaker bill. Double-crested's forehead slopes more evenly into the bill. While these differences may be difficult to see in single birds without comparative experience, in direct comparison they are significant. Additionally, the orange facial skin combines with the gular pouch to accentuate the overall orange color of the face. Other extralimital black cormorants can be ruled out on size alone, additionally, most have thinner necks and smaller bills than even Double-crested. | The original documentation form event lasted from 11:00:00/11:02:00.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Another documentation form by Jim Fuller was submitted later. Other observers include Jim Scheib and Dick Tetrault. | Elimination of similar species: The chunky body, relatively short legs, feeding pattern, and lack of white rump led me away from Stilt Sandpiper. The bill was much too short for dowitcher. The bill was not curved enough for Curlew Sandpiper. These birds appeared to be partially molted into alternate plumage. | The original documentation form event lasted from 08:35:00/08:45:00 and 10:30:00.

The documentation form by Ross Silcock is the only one submitted and forms the basis of this record. Other observers include B.J. Rose, Roger Rose, and Doug Rose. | Elimination of similar species: [...] It resembled a Pectoral Sandpiper, but differed in the following ways: the crown was streaked, and showed noticeable rufous coloration in the feathering; the off-white superciliary stripe was lengthy and broadened towards the rear; the breast markings were dense as in a Pectoral but did not show a clearcut ending at the whitish belly, but instead ended indeterminately by gradually fading out. [...] Once ready to record, we flushed the bird and it gave a soft series of notes, somewhat like a Lesser Yellowlegs, but rather flat and unmelodious. This call was most unlike the harsh, grating call of a Pectoral Sandpiper. [...] Plumage, time of year, call upon flushing, and key plumage differences from Pectoral Sandpiper, cited above, led us to identify this bird as an adult Sharp-tailed Sandpiper. | The original documentation form event occurred around 10:30:00.
