[...] They were too thin for female purple finches and lacked any trace of a white eyeline. They were too streaked to be indigo buntings (wrong color as well). I thought of possible pine siskins but there was no yellow visible on wings on tail (wingbars of any color were not noted), the bill was short and stout-not as thin as siskin, and the tail did not show deep notch in terminal end - had fairly shallow "V" notch. | The original documentation form event lasted from 09:05:00/09:10:00.

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 Robert K. Myers forms the basis of this record. Another documentation form by Maridel Jackson was submitted. Other observers include Walt Jackson, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: [...] I first noticed this bird as we were scanning a bunch of dunlin and this bird "stuck out." [...] The bird was about the size of a lesser yellowlegs (also present) but was of different proportions. The body was too heavy (chunky) for a yellowlegs - being more dowitcher like. The neck was fairly long - more so than a dowticher but maybe a little shorter than lesser yellowlegs. The head was defnitely small for the size of the bird. The legs were also fairly long (knobby knees) and again probably a little shorter than a lesser yellowlegs. These basic proportions helped at once to eliminate many species. [..] The bird's head and upper neck were very tawny (similar to buff breasted sandpiper) [...] Tail - This is the one feature along with the basic shape that convinced me. [...] If the bird would have had no color at all I still would have called it a ruff from the proportions. Ruff plumage is variable to say the least. | The original documentation form event lasted from approximately 15:00:00/15:45:00.

The documentation form by Robert E. Thornburg is the only one submitted and forms the basis of this record. | Elimination of similar species: The American Kestrel is of a similar shape, but is smaller and usually has some reddish plumage on the back or tail. The Sharp-shinned Hawk is similar in size and color especially the immature. The long-pointed wings of the Merlin differ from the wings of the Sharp-shinned Hawk. The overall posture of the bird did not suggest an accipiter. | The original documentation form event lasted from 09:00:00/09:05:00.
