Magnificent Frigatebird	Lake Red Rock	Behind Visitor Center at Lake Red Rock, Marion Co., IA	Freshwater lake shore	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.

Also this complex normally has more distinct white wing bars on darker wings and the streaking on the sides is not the stark black on brilliant yellow but a more muted yellowish wash. \| The original documentation form event lasted from 18:45:00/18:45:00.
