Other observers include Tom Johnson. | Elimination of similar species: The uniform forewing and back and the thickness of the bill separate this species from Red-necked Phalarope. | The original documentation form event lasted from 07:55:00/08:00:00, 08:15:00/08:20:00, and 11:30:00.

Compared directly to a Sanderling, this bird had a longer neck, a dark cap, a black spot around the eye, and darker upperwings which were particularly visible in flight. Red-necked Phalarope (which would be even more unusual at this date) was eliminated by bill size and shape and unstreaked mantle. | The original documentation form event lasted from 09:35:00/10:15:00.

Red-necked Phalarope is superficially similar but the bill is much more needle-like. Furthermore, Red-necked has the gray extending further onto the crown, shows white streaking on the back, and would not have remnants of red color on the throat and upper foreneck. | The original documentation form event lasted from 17:00:00/17:05:00.

In addition, I had the opportunity to observe the Pomarine Jaegers earlier this fall at the same location and the markings were similar, except this bird was darker with a white belly. | The original documentation form event lasted from 14:40:00/14:40:25.

Bill was gull-like, but hooked mail different. May have been exagerated [sic] by a darker color than basal portion. Flight was direct and strong, a "confident" feel I get from birds of prey. | The original documentation form event occurred around an estimated 11:15:00.

At the time I did not realize the importance of this detail, but I recorded it along with my other field notes as I knew from past reading that distinguishing between Long-tailed and Parasitic Jaegers could be tricky. | The original documentation form event occurred around 18:00:00.

Other jaeger species were eliminated by the bird's size. It thermalled above a wetland area beyond HNA's 'Westridge' with a group of Ring-billed Gulls.

The large size compared to Ring-billed Gulls, heavy build, large, thick bill, prominent white patches on the upper and under surface on the wings, and the presence of a second white "crescent" on the underwing at the base of the primary coverts eliminate both Parasitic and Long-tailed Jaegers. | The original documentation form event lasted from 12:24:00/14:46:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Another documentation form by James J. Dinsmore was submitted later. | Elimination of similar species: The dark coloration, gull-like shape, and white color in the primary shafts identified both birds as jaegers. Initially, I thought the bird I saw on the 10th was a Parasitic, mainly because of the size and seemingly bright, rust-colored underparts. However, better viewing conditions later showed that the underparts were instead a pale brown color and lacked any hint of rusty color. Long-tailed Jaeger was easily eliminated by size, shape of the central rectrices, and the greater amount of white in the wing. Parasitic Jaeger was more difficult to rule out. The combination of size, wing shape, amount of white in the wing, shape of the central rectrices, and bill size was used to rule out juvenile Parasitic Jaeger. | The original documentation form event lasted from 09:35:00/12:33:00 on November 10, 1996 and 10:55:00/16:05:00 on November 11, 1996.

The documentation form by Stephen J. Dinsmore forms the basis of this record. Other documentation forms by Jim Fuller, Thomas H. Kent, Chris Edwards, and Ray Cummins were submitted. Other observers include Tom Johnson, Dennis Henrickson, Jim Sinclair, and many unidentified other observers. | Elimination of similar species: The size, shape, and white in the primaries ruled out all gull species. The combination of size, the large bill, large amount of white on the upperwing, white color in the underpirimary coverts, and blunt-tipped central rectrices rule out juvenile Long-tailed and Parasitic jaegers. | The original documentation form event lasted from 13:12:00/13:55:00 on November 16, 1996 and 15:40:00/16:30:00 on November 27, 1996.

The documentation form by Robert K. Myers is the one that forms the basis of this record. Other documentation forms by Stephen Dinsmore, Francis L. Moore, Carl J. Bendorf, Thomas H. Kent, and Bery Engebretsen were submitted. Other observers include Dennis Thompson, Eloise Armstrong, Eugene Armstrong, Tom Staudt, and many unidentified observers. | Elimination of similar species: Pomarine Jaeger and Long-tailed Jaeger are possible. See explanation on back as to why I believe this was Parasitic Jaeger. [...] A juvenile dark phase Pomarine would also show much white in the base of primaries (top and bottom) and the tail wouldn't have any long streamers. The Pomarine should however be a larger bird (Herring Gull size). The Pomarine's flight should be slower and more labored than this bird was. A juvenile dark phase Long-tailed Jaeger would not show as much white on dorsal side of primaries as this bird did and the flight pattern should be almost tern-like which it was not. Long-tailed Jaegers should also appear to be more grayish than the bird in question- even in dark phase. Further note on size-- As the jaeger rested on the water, double-crested cormorants would sometimes swim into the field of view and they appeared to be at least one-third larger than the jaeger. A pied-billed grebe also swam near once and the jaeger was probably 1/4 again longer than the grebe. | The original documentation form event lasted from 09:15:00/09:40:00 and seen several times after that for a total of sixty minutes.

The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen and Jim Sinclair. | Elimination of similar species: The dark color and white patches on the wings eliminates all larids except jaegers. The noticeable amount of white on the wing, visible on the underside of the wing, eliminates Long-tailed Jaeger. The small size compared to a Ring-billed Gull, less prominent white on the wing, smaller bill size, and more rapid wing strokes eliminates Pomarine Jaeger. | The original documentation form event lasted from 16:46:00/17:14:00 on September 29, 1988 and 10:15:00/10:35:00 on September 30, 1988.

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.
