The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Susan Grove, Eugene Armstrong, and Eloise Armstrong. | Elimination of similar species: On the basis of size and general plumage characters, this species could only be confused with Ring-billed Gull, hundreds of which were available for direct comparison. The combination of slightly smaller size, distinct head shape, bill color and shape, dark eye, and slightly darker mantle and upperwings are sufficient to eliminate Ring-billed Gull. | The original documentation form event lasted from 15:42:00/16:53:00.

[...] The size was slightly but noticeably smaller than all the Ring-billeds present. The head was more rounded in appearance than the ring-billeds. The bill was smaller in portion than the Ring-billeds, both shorter and thinner. [...] The tail was black, but not as black as side by side comparisons with the adult Ring-billeds. | The original documentation form event lasted from 07:45:00/08:05:00.

The bill shape, dark cap that included the eye, and presence of two white patches on each side eliminates all other murrelets, especially Kittlitz's. | The original documentation form event lasted from 15:15:00/15:24:00.

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.

The documentation form by Peter Ernzen is the only one submitted and forms the basis of this record. Other observers include Joshua Ernzen. | Elimination of similar species: [...] Whimbrel was eliminated by size, color and bill size. The whimbrel should have been slightly smaller to about the same size as the marbled godwits. The brown body and cinnamon wing linings did not fit whimbrel either. The bill size is variable with shorebirds, however the great length of the bill was more suggestive of the long billed curlew. The call heard does not fit the description for whimbrel in my National Geographics [sic] Field guide to Birds of North America. Three outside possibilities the far Eastern curlew, Eurasian curlew, and bristle thighed curlew were eliminated as well. The far Eastern curlew size is about the same as that of the marbled godwit. The bird also has white wing linings with dark barring. The barring would be hard to see, however the lighter color would be distinguishable. The Eurasion [sic] curlew was eliminated because this bird would have a white rump, and white wing linings. The bird I saw in flight turned and twisted. I did not notice any white markings on the rump. The bristle thighed curlew is much more similar to the smaller whimbrel and would be eliminated by small size, shorter bill and call - "chu-a-wut". | The original documentation form event lasted from 19:50:00/20:00:00.

The black underside of the flight feathers, pale gray mantle and wings, white wingtips, and rounded wings eliminates Bonaparte's and Sabine's gulls and kittiwakes.

Franklin's and Laughing Gull would be larger, darker mantled and have a prominent eye ring. Sabine's Gull would've had a bicolored bill, forked tail and different - white triangular - pattern to its wings. The larger Common Black-headed Gull looks like a larger version of a Bonaparte's Gull with a brownish hood and a red bill. The associated Bonaparte's Gulls were darker mantled and larger. The wings were more angular in appearance with a white leading edge and black wing tips. I have observed all but the Laughing Gull - though the Sabine's Gulls were immature, the distinctive wing pattern is present in both adults and immatures - and feel confident in calling this an adult Little Gull. | The original documentation form event lasted from 10:15:00/10:30:00 and 11:00:00/11:08:00.

The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen. | Elimination of similar species: The size (larger than Ring-billed Gull, smaller than Herring Gull) eliminates all Gulls except Herring, California, and Lesser Black-backed gulls. The mantle was much too dark for a Herring Gull. Separation from California Gull is much more difficult. Obviously, the mantle color of this bird was much too dark for a California Gull, and the legs were more yellow than the legs of a California Gull. | The original documentation form event lasted from 15:44:00/16:38:00.

The documentation form by Jim and Karole Fuller is the only one submitted and forms the basis of this record. | Elimination of similar species: All other adult dark mantled gulls have pink legs, except the Yellow-footed gull which is seen at the Salton Sea, and extreme southwest California. That bird has never been seen away from that area, and should be noticeably larger than a Lesser black backed gull. The European race of the Herring gull has yellow legs, and one has been seen on the east coast the past two winters. That bird should be larger, and does not have a dark mantle. | The original documentation form event lasted from 14:03:00/14:27:00.
