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.

The documentation form by Ann Johnson is the earliest and thels, one an adult male and the other a probable adult female, were present on the same day. Oftentimes all three birds were on the feeder concurrently which allowed for a number of comparisons. Characteristics which differentiated this bird from the Common Redpolls and identified it as a Hoary Redpoll: underlying color was lighter than the warmer, darker brown of the Commons, More extensive white feather edgings to the secondaries, tertials, and scapulars than shown on Commons, Broad white edge to the greater coverts, Buffy face and strong white supercilliary, Smaller red cap, Broken and shorter flank streaking, Short, triangular bill with resulting pushed in face, Nearly white undertail covers (Although brightly colored adult male Common Redpolls may have diminished markings on their undertail coverts, this bird had no red except for the cap.) | The original documentation form event lasted from 07:30:00 and periodically throughout the day. one that forms the basis of this record. Other documentation forms by Jim Sinclair, Stephen Dinsmore, and Jim Fuller were submitted later.

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.

The documentation form by Carl J. Bendorf forms the basis of this record. Other documentation forms by Thomas H. Kent, Francis L. Moore, Bob Myers, Beth Proescholdt and Mark Proescholdt, and Dennis Thompson were submitted. Other observers include Joe Schaufenbuel, Darwin Koenig, Steve Dinsmore, Eugene Armstrong, Eloise Armstrong, and many unidentified observers. | Elimination of similar species: Thayer's Gull is a difficult bird to identify. In researching this problem, I have found several helpful sources in addition to the standard field guides and I have tried to understand what it takes to know a Thayer's Gull when you see one. Nearly every reference makes it clear that Thayer's cannot be identified on the basis of one or two positive field marks. It takes a combination of characters to come to a conclusion of any certainty. In discussing this particular observation, I will examine each of the fieldmarks and compare and contrast to similar species with liberal reference to the literature, especially Lehman (1980). The most likely similar gulls in this case are 1st winter Herring and 1st winter Iceland (Kumlien's). The Kumlien's form is the darker form of the Iceland Gull and is the form that breeds in the Baffin Island area and winters mainly on the Atlantic coast. Lehman's article deals mainly with Kumlien's. Several similarly sized and possible but unlikely candidates can be eliminated rather quickly. A 1st winter California should not have an all dark bill and would show much darkening in the primaries in flight. Lesser Black-backed Gull could be about the right size, but in flight a 1st winter bird should show darker primary and secondary coverts, more extensively dark primaries, even compared to Herring Gull. A 1st summer Slaty-backed Gull is also light uniform brown with an all dark bill, but it should exhibit extensive darkening in the primaries on the upper wing. A 1st winter Glaucous-winged Gull would be very similar to Thayer's but should be larger, with a larger bill, and less mottling to the body color. Except for the first two, one would probably not consider the likelihood of their occurrence in Iowa to be very great. One hybrid, Glaucous-winged X Western, might be similar but should have a quite heavy bill. [...] Summary: Of the most likely similar species, 1st winter Herring Gull and 1st winter Kumlien's Iceland Gull, each is eliminated by one or more of the features discussed above. The wing pattern is especially damaging to the possibility of Herring, along with the bill shape and size. Iceland is ruled out by the presence of the noticeable tail band and by the darker secondaries on the upper wing. To identify a Thayer's Gull, one must see a combination of field marks. I feel that the bird I saw at Red Rock is consistent on every point.| The original documentation form event lasted from 14:15:00/14:45:00.

Other observers include Tom Staudt, James G. Huntington, John L. Cordell, Tom Kent, and Mike Newlon. | Elimination of similar species: According to Robbins, et al., Bristle-thighed Curlew should have a bright rusty tail. This was not observed. Robbins shows Eskimo Curlew with much more barring on flanks, smaller bill. | The original documentation form event lasted from 10:15:00/10:30:00.

Moore, and Gerald White were submitted later. Other observers include Peter C. Petersen and Jim Fuller. | Elimination of similar species: Surf Scoter is another all dark bird, but it would have a much larger bill that extends on the same angle as a flattened forehead. The definite gray cheek and throat are not present on Surf Scoter. Female Ruddy ducks should be much browner and again have a flattened forehead in line with a larger bill. Black wings eliminate White-winged Scoter. | The original documentation form event lasted from 10:15:00/10:35:00.
