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 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.

Long-tailed Jaeger is eliminated by the presence of a white crescent on the upper surface of the wing.

|
Saylorville Lake
|
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.

|
The documentation form by Thomas Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Fuller were submitted later. | Elimination of similar species: We based our identification on size, small uniform bill, lack of white around and in front of the eye, sharp separation of light and dark on the neck, and fine chin strap. The bird was too bulky for a Red-throated Loon and did not have a very thin, upward pointing bill. We were more concerned about excluding Common Loon. The Common Loons we saw later at Rathbun Reservoir had white around the eye, more irregular and less distinct separation of light and dark on the neck, and much more massive bills with bulbous thickening near the tip. | The original documentation form event lasted from 07:25:00/07:40:00.

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.
