Includes a record review document with votes and a documentation form submitted to the committee.	Dinsmore, Stephen J.	Parasitic Jaeger	Cherry Glen Recreation Area	Saylorville Reservoir, Polk Co.-off Cherry Glen Recreation Area		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.

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.

Includes a record review document with votes, an article of Iowa Bird Life, and six documentation forms submitted to the committee.	Myers, Robert K.	Parasitic Jaeger	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.
