Other observers include Chris Pilliod, Jim Sandrock, Cal Knight, Jane Fuller, Charles Fuller, and James Huntington. | Elimination of similar species: The only species I could not eliminate on the basis of field marks observed was Yellow-footed, which according to Tom Kent (telephone conversation) is not a known vagrant. More objectively, the Yellow-footed is supposed to be larger than a Herring Gull. As stated above, this bird was about the size of a Herring Gull, or perhaps a little smaller. I don't feel it was larger than a Herring Gull. Seabirds (Harrison) warns of possible confusion with dark race Herring Gull. I have not heard of this race occuring [sic] in Iowa. In any event, the foot coloring was incorrect for Herring Gull, which has pink legs in contrast to this bird's yellow legs. | The original documentation form event occurred at various times.

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.

The documentation form by Dawn L. DeVore is the earliest and the one that forms the basis of this record. | Elimination of similar species: After getting the bird book, I took my knowledge of the birds in the area and my mental picture and went to work. I ruled out the turkey vulture because the bird was too streamlined like a tern. I looked at the terns, soon realizing that there were no almost completely black terns. Thus I turned to the gulls. I knew it had to be a water area type bird because of its body and bill shape. Remembering the bill I quickly ruled out the gulls. Thus I turned to the cormorants but the tail was wrong, the neck was too long and more so the cormorant was out of the picture. Thinking I recalled hearing about a sighting of a rare bird in Iowa, only the night before had I looked at an outline of its body shape. Bingo! That was it! The shapes matched but what was the name? I went through the bird section page by page. Then there it was - the Magnificent Frigatebird. This was it; almost all black, large yet streamlined, "forked" or V shaped "tail", and that unique bill. Then the fact that the bird I saw had no red and two side by side white breast areas confirmed that it was a female Magnificent Frigatebird. | The original documentation form event lasted from 12:45:00/12:50:00.
