This bird's bill was more like that of a Eared Grebe; that is, very slender and not as loon-like as that of Pacific Loon. Pacific Loon's bill looks like a small Common Loon. Pacific Loon's bill looks like a small Common Loon. Common Loon: eliminated by size of bird, shape of bill, and red throated patch. | The original documentation form event lasted from 16:15:00/16:45:00.

This bird was also still in basic plumage, making it much paler in color than the other peeps.

The documentation form by Ann Johnson is only one submitted and forms the basis of this record. Other observers include Mike Thomas. | Elimination of similar species: Although I understand the difficulty in identification of fall western sandpipers, the Baird's and white-rumped were eliminated because of wing length. The least sandpiper was eliminated by leg color and bill shape/size. The most difficult elimination was that of the semipalmateds, especially since other semipals were present in the area. After careful observation and comparison, however, the prototypical western sandpiper bill was too obvious to make the bird into a semipalmated. The bill was enough longer and had an obvious droop. The others in the area had varying bill sizes but none had the general shape of this bird. Consequently, I believe this was a late date western sandpiper. | The original documentation form event lasted from approximately 15:00:00/15:10:00.

We also listened to "A Field Guide to Bird Songs" and although the Sharp-shinned recording was that of 175 "kek-kek-kek" warning/alarm call, the Cooper's Hawk recording was that of a food begging call which was very similar but of a significantly lower pitch than that of the bird we observed. | The original documentation form event lasted from 14:30:00/14:31:00.

The documentation form by Robert Myers is the earliest and the one that forms the basis of this record. Another documentation form by Francis L. Moore was submitted later. | Elimination of similar species: Fall scarlet tanager is possible - see attached page. My first thought was that this was late for a scarlet Tanager and when I looked closer I saw the wing bars. My second thought was that someone told me that one of a hunderd [sic] ♀ scarlets have wing bars. I also knew the Peterson Guide says some scarlets have two wing bars. When I went home that night I was anything but convinced the bird was a western tanager even though most literature states wing bars = western tanager. When I got home I phoned Fancis Moore and he went to the park and was able to relocate the bird. Even though he had never seen western tanagers before, Francis thought this was one. His enthusiasm prompted me to research further. I am now also convinced that this bird was indeed a western tanager no matter how unlikely it seems. Ironically, my first western tanager, a male seen April 26, 1980 at Forney Lake, was also with a mixed flock of yellow-rump + palm warblers. | The original documentation form event lasted from 16:00:00/16:15:00.

Larger than Ring-billed Gulls- flock of 14 adjacent. [...] Headmuch [sic] smaller relative to body than in the Herring Gull- also flatter-appearing. [...] 1. Bill was black (or very dark); this , combined with the rather pale underparts relative to the rest of the (also rather pale) plumage tends to rule out a first year Herring Gull. 2. Bill and head size and shape were not as heavy-appearing as in Herring Gull. Direct comparison with adjacent adult Herring Gull was very useful in deciding this. [...] 5. Size and pinker legs than Herring Gull are not sure characters, but lend support to identification as Thayer's Gull.

Bill was same length as a Herring Gull's but was blunter, not as strongly hooked. [...] The primaries were not nearly as dark as immature (1st year) or 2nd year Herring Gulls and was of a much different color than the black color of that species. Primaries and tail were nearly the same color. [...] In flight this bird could be easily picked out from the immature Herring Gulls at considerable distances. Using 7x35 binoculars the beige color of the upper surface of wings and translucent underwing could be detected as far as three-quarters of a mile. There were also three other birds that resembled this particular bird though they appeared darker on the upperparts. However I was unable to get close observations of these birds. The bird I observed closely and documented had one primary feather missing and aided in tracking the bird from day to day.

The documentation form by Francis L. Moore is the only one submitted and forms the basis of this record. Other observers include Russell Hays, Tom Kent, Tom Shires, Tom Staudt, and many unidentified other observers. | Elimination of similar species: Ring-billed Gull and Herring Gull, see above. The Ring-billed Gulls were seen in direct contrast to these three birds and were definitely much smaller birds. The Herring Gulls (first year birds) that I have seen have more of a contrast between the rump and back and upper wing surfaces and none that I remember showed the whitish trailing edge on the tail. [...] The three birds seen were about the size of Herring Gulls in typical first year plumage. They were obviously large gulls of the genus Larus with a noticeably larger size than the Ring-billed Gulls and one Bonaparte's Gull that were next to the three larger birds. [...] There were no Herring Gulls nearby with which to make a comparison of size and coloration. The bills of all three gulls were black did not seem as heavy or bulky as the bill of a Herring Gull. | The original documentation form event lasted from 08:10:00/09:30:00.

The documentation form by Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Carl Bendorf, Mike Newlon, and many unidentified other observers. | Elimination of similar species: Photographs taken at the first encounter with a Celestron 750 mm lens demonstrate the size difference, the bill and head shape difference, the lighter overall color, and the window in the wing. An adult Herring was in the photo with the Thayer's on 7 Nov and imm Herring were photographed on 10 Nov for comparison. | The original documentation form event lasted from 09:25:00/09:50:00 and 11:00:00/11:20:00 on November 7, 1981 and 07:30:00/08:30:00 on November 8, 1981.

The documentation form by Ross Silcock is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Peter C. Petersen, and Robert K. Myers were submitted later. Other observers include Tom Shires, James Kovanda, Sandra Kovanda, Tanya Bray, Babs Padelford, Loren Padelford, B.J. Rose, and four unidentified other observers. | Elimination of similar species: The above description separates by direct comparison first-year Thayer's and Herring Gulls, the most similar species present. Thayer's may be confused in first year plumage with Kumlien's form of Iceland Gull, but the Thayer's had primaries slightly darker than the mantle (from above), whereas the opposite occurs in Iceland Gull (Lehman). Lehman also notes that some first-year Western Gulls may show translucent primaries from below in certain light, but these observations took place in excellent light at fairly close range. | The original documentation form event lasted from approximately 09:30:00/11:00:00.

The documentation form by Woodward H. Brown is the earliest and the one that forms the basis of this record. Another documentation form by Nicholas Halmi was submitted later. Other observers include Eugene Armstrong, Eloise Armstrong, Mary Brown, Dorothy Ely, Peter C. Petersen, Mary Lou Petersen, Margaret Brooke, Lillian Serbousek, Allen Mueller, and many unidentified observers. | Elimination of similar species: [...] According to plumage descriptions of the Pigmy and Brown-headed Nuthatches, the only noticeable difference between the two (short of having the bird in hand) is in the color of the crown and nape. The field guides are agreed that the crown of the Brown-headed is brown, but there is a lack of unanimity in their descriptions of the crown of the Pigmy. [...] Margaret Brooke, in writing up the observation for IBL, describes the cap as being "brownish" but has no doubt about this nuthatch being a Pigmy. Mary and I feel the grayish olive description comes closest and cinches the Pigmy identification. | The original documentation form event occurred around 09:30:00.
