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, Ann Johnson, and Carol Thompson. 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.

Other observers include Pam Allen, Reid Allen, and many unidentified other observers. | Elimination of similar species: There are very few shorebirds that are this pale. 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.

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 Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Bob Myers, Thomas H. Kent, Peter C. Petersen, Beth Proescholdt, and Mark Proescholdt were submitted later. Other observers include Babs Padelford, Loren Padelford, Jim Sinclair, Bery Engebretsen, Eugene Armstrong, Eloise Armstrong, Jim Dinsmore, Jim Fuller, Brian Blevins, and many unidentified other observers. | Elimination of similar species: The gull-like shape, dark color, and white wing patches eliminate all birds except Jaegers. 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 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.

Saylorville Reservoir, Polk Co., Iowa

General: Saylorville Reservoir- large impoundment on DesMoines [sic] River. Specific: Always out in main deeper part of lake.
|
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.

Other documentation forms by Loren Padelford, Babs Padelford, and Bob Myers were submitted later. Other observers include Bob Myers, B.J. Rose, Jim Dinsmore, Gene Armstrong, and Eloise Armstrong. | Elimination of similar species: Common Loon eliminated by the small bill, rounded forehead, clear separation between the throat and back of neck, smaller size, chin strap, and dark, mostly unmarked back. Red-throated Loon eliminated by thicker, straighter bill, dark back, chin strap, and 3-toned neck pattern. | The original documentation form event lasted from 11:15:00 - 11:30:00 and 11:45:00.- 12:30:00 on November 22 and 08:00:00/08:35:00 on November 23.

The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. | Elimination of similar species: Common Loon eliminated by the more rounded forehead, the smaller, darker bill, the paler nape and crown, the gray necklace on the throat, and by the overall smaller size(a small Common Loon should still show the features of a normal Common Loon). Red-throated Loon was separated by the straight (not upturned) bill, the dark, unspeckled [sic] back, and the gray necklace. | The original documentation form event lasted from 15:00:00/15:20:00.
