Includes a record review document with votes, an article in American Birds, excerpts from Western Birds, articles in Pennsylvania birds, an article in Iowa Bird Life, correspondence relevant to bird sighting and review, eight photographs, and four documentation forms submitted to the committee.	Johnson, Ann	Empidonax Flycatchers	Lake Ahquabi State Park	Lake Ahquabi State Park, Warren County, IOWA	Woodland edge consisting primarily of honeysuckle and junipers	The documentation form by Ann Johnson is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent, Jim Fuller, and Brian Blevins were submitted later. Other observers include Ross Silcock, Peter Petersen, Kelly McKay, Corey Blevins, Jim Scheib, Jim Sinclair, John Daniel, Tim Schantz, Cal Knight, Bernie Knight, Chuck Fuller, David Youngblut, Beth Brown, Sherry Dragula, Bill Overland, Jane Overland, John Miller, Eugene Armstrong, Eloise Armstrong, and unidentified other observers. \| Elimination of similar species: The date of observation is historically good for a vagrant western flycatcher species, so this was in the back of my mind in assessing the characteristics observed. The presence of both eye ring and wing bars, in addition to size and shape, indicate that the bird fits the Empidonax complex. The combination of green back, yellow throat and pure orange lower mandible with no markings would eliminate Least, Hammond's, Dusky, Gray, Buff-breasted, Alder, and Willow Flycatchers. A juvenile Acadian can be eliminated by the short primary extension, color of the wings, size and shape of the eye ring, and active behavior. Only three species are indicated by the green upper parts and yellow under parts. Two are separable only by voice. The choices were between Yellow-bellied Flycatcher and Western (Cordilleran and Pacific-slope) Flycatcher. Back color is greener in Yellow-bellied and more olive in Western. Although the back looked olive, this was rather subjective. According to the Audubon Master Guide, behavior would be more indicative of a Yellow-bellied in that the bird was not flicking both tail and wings. According to Kaufman, however, behavior is quite variable. Three characteristics made me lean more toward Western complex. They were peaked appearance to the head (usually smooth and rounded in Yellow-bellied); almond-shaped eye ring (round, narrow, and more even in Yellow-bellied); and browner wings than eastern Empidonax. The color of the wings is again subjective, but the contrast between wing color and wing bars was less than the black/white (or even black/buff in fall birds) of eastern birds. Even with the variability that may occur in any Empidonax, it is unlikely that these three characteristics, which are common to the Western Flycatcher, would appear simultaneously in a Yellow-bellied Flycatcher. Further support is found in the Audubon Master Guide to Birding where it states in the description of Western Flycatcher, "...olive wash on the breast, flanks, and especially the sides tends to highlight a midventral yellow stripe" - one of the more obvious characteristics when viewed at close range from the front. IF the call notes heard belonged to this bird, it would indicate a Cordilleran Flycatacher, the most likely vagrant. None of us were able, however, to get the bird to call as we were observing it. Cal Knight played a tape and the bird became very agitated but did not call. \| The original documentation form event lasted from 11:00:00/14:00:00 on November 14, 1992 and 11:30:00/13:45:00 on November 15, 1992.

Fuller, James L	Rufous Hummingbird	Cedar Rapids	Backyard of Barbara Stark, 238 24th Street Dr., Cedar Rapids (Linn County)		The documentation form by Jim Fuller is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas Kent, Chris Edwards, and Peter Petersen were submitted later. Other observers include Weir Nelson, Pam and Reid Allen, Carol [sic] Thompson, Corey Blevins, Mary Lou Petersen, Chris Caster, Tim Schantz, Eugene Armstrong, Eloise Armstrong, Robert and K. Bradley, A. Martin, Ann Barber and Jim Durbin. \| Elimination of similar species: I would identify this bird as a member of the Selasphorus complex. Because of the rufous on the back just above the wing it is most likely a Rufous or Allen's, and of those two, Rufous would be more likely from its range. \| The original documentation form event lasted from 11:00:00/11:02:00 on November 4, 10:45:00/11:45:00 on November 5, and 12:05:00/12:10:00 on November 9.

Fuller, James L	Ruby-throated Hummingbird	Cedar Rapids	Gary Heiberger residence, 3350 Circle Drive, NE, Cedar Rapids (Linn County)		The documentation form by James Fuller is the earliest and the one that forms the basis of this record. Another documentation form by Thomas Kent was submitted later. Other observers include Allen Martin, and Jane Fuller. \| Elimination of similar species: Anna's Hummingbird has gray (not white) underparts. Kaufman's 'Advanced Birding' suggests that female and immature male Ruby-throated and Black-chinned cannot be identified except in the hand. This bird may have been molting into first alternate plumage, because of the red circular area on the throat. It would seem that an area such as this would be red in a Ruby-throat and purple in Black-chinned. \| The original documentation form event lasted from 07:55:00/08:45:00.

Includes a record review document with votes, photographs, an article in Iowa Bird Life, two letters from Carole Stolz to T.H. Kent, a letter from Louis Bevier to Tom Kent, e-mail exchanges, and a documentation form submitted to the committee.	Kent, Thomas H. (Thomas Hugh), 1934-	Amazilias	Des Moines	512 SW 60th St., Des Moines, Polk Co., IA	Rather open urban area on southwest side of Des Moines in bottom land. There is a large deck behind the house with hummingbird feeder hanging from the eve and crab apple tree behind the deck and adjacent to the garage. A large vacant field is behind the property.	The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record. Other observers include Don Stolz, Carole Stolz, Eugene Armstrong, Eloise Armstrong, Pam Allen, Reid Allen, Ann Johnson, Jim Dinsmore, Jim Fuller, Bob Cecil, and Aaron Brees. \| Elimination of similar species: My experience and references of Buff-bellied Hummingbird suggest that the cinnamon color, extent of this color toward the throat, cinnamon rump/back, and white eye spot do not fit this species. I believe that the features shown in the photo of the Arizona 'mystery' bird in Field Notes are a perfect fit for the Des Moines bird. I do not know of specific information on bird trafficking in Iowa. We had a Yellow Grosbeak north of Des Moines in December 1990, the origin of which was never explained. \| The original documentation form event lasted from 07:50:00/08:40:00.

Dinsmore, Dick Tetrault, Chris Caster, Dale Fye, Diane Porter, Ron Muilenberg, Gerald White, Jan Walter, Rita Pedelty, Tom Fischer, and many unidentified observers. \| Elimination of similar species: There really is no other owl except a Barred Owl which could be confused with this bird. The yellow eyes of the Great Gray Owl eliminated the possibility of a Barred Owl which has dark eyes. Also, size would eliminate the Barred Owl. The Great Gray Owl looked almost twice as large as a Barred Owl. \| The original documentation form event lasted from 14:52:00/16:09:00.	Iowa Ornithologists' Union \| MS 166	12	18

Baum were submitted. Other observers include Mary Lou Petersen, Cal Knight, Bernie Knight, Tom Rockwell, Lewis Blevins, Brian Blevins, Don Moeller, Walter Zuurdeeg, Daryl Tessen, Doug Rose, Alan Grenon, and many unidentified observers. \| Elimination of similar species: (A) Greater black backed - Gull in question has slaty - gray saddle rather than coal black. And Gull in question is same size as Herring Gulls; Greater black-backed would be much larger. (B) Lesser black backed - Gull in question has pink legs and feet, and has much more white on primaries. (C) Western - Gull in question has considerable white on primaries, and does not show dusky trailing edge to underwing. Also has broader white trailing edge to upperwing than would the Western. (D) Herring Gull - dark race - no experience with this, but those shown in Harrison do not show as dark a saddle as Gull in question, nor as much white on primaries. \| The original documentation form event lasted from 15:00:00/15:30:00 on February 12, 1989, 12:15:00/12:45:00 and 16:00:00/17:30:00 on February 14, 1989.

Other observers include Kay Niyo, Curt Nelson, Jan Walter, Chris Wood, and Jim Sandrock. \| Elimination of similar species: [...] We saw this gull twice in our viewing time and debated if it was an adult Kumlien's Iceland Gull or an adult Thayer's Gull. It was an adult Kumlien's Iceland Gull because a Thayer's Gull has much more blackish coloration at the primary tips and more dark coloration at the primary tips than the Kumlien's which has grayish markings on the primary tips and less dark-colored markings at the primary tips overall. Also, a Kumlien's Iceland Gull shows the almost white wing tips like we saw with a little grayish markings on some primary tips. \| The original documentation form event lasted from approximately 15:00:00/16:15:00.

Other documentation forms by Thomas H. Kent and Jim Fuller were submitted later. Another observer includes Chuck Fuller. \| Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). \| The original documentation form event lasted from 11:30:00/13:10:00.

Other observers include Dan Dorrance and many unidentified observers. \| Elimination of similar species: The overall size, head size, bill size, and lack of dipped-in-ink effect on the bill tip exclude Glaucous Gull. I excluded Thayer's Gull because both of these birds had very light primaries (not dark webs on the outer primaries). Neither had a secondary bar or in fact any distinctive marking on the wings. The lack of tail band in the first year bird also excludes Thayer's Gull. I was impressed by the paleness of the gray mantle in the second-year bird, but have too little experience with older Thayer's Gulls to make a comparison. \| The original documentation form event lasted from 11:30:00/12:30:00.

Kent is the earliest and the one that forms the basis of this record. Other documentation forms by Robert Cecil, James Fuller, Ann Johnson, Peter C. Petersen, Raymond Cummins, Randall Pinkston were submitted later. Other observers include Beth Brown, Dan Dorrance, Ross Silcock, Tanya Bray, Pete Wickham, Tim Schantz, and many unidentified observers. \| Elimination of similar species: The overall size, head size, bill size, and lack of dipped-in-ink effect on the bill tip exclude Glaucous Gull. I excluded Thayer's Gull because both of these birds had very light primaries (not dark webs on the outer primaries). Neither had a secondary bar or in fact any distinctive marking on the wings. The lack of tail band in the first year bird also excludes Thayer's Gull. I was impressed by the paleness of the gray mantle in the second-year bird, but have too little experience with older Thayer's Gulls to make a comparison. \| The original documentation form event lasted from 11:30:00/12:30:00.

If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

Other observers include John Cecil, Tom Kent, and Francis Moore. \| Elimination of similar species: Only probable similar species is Herring, which has contrasty wings - dark trailing edge and darker wingtips. The Thayer's were obviously a lighter shade of brown than any Herrings present. I judged these birds to be somewhat smaller than any Herring. I could not totally rule out first year Glaucous-winged. According to NGS, Glaucous-wing has less mottling or scalloping. The Keokuk birds were obviously mottled. \| The original documentation form event lasted from 11:05:00/11:30:00.

(Runnells W.A.)	pool of shallow water	The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Sinclair, Thomas H. Kent, and Jim Fuller were submitted later. \| Elimination of similar species: Ring-billed and Herring gulls are the two most likely species of confusion. Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. \| The original documentation form event lasted from 10:55:00/12:24:00.
