The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: This smaller loon was dark gray across the back and wings, slightly darker than the Common Loon with it. [...] The whole neck pattern was much different and cleaner looking than the Common Loon. The bill was dark, short, and straight. It was about 1/3 shorter than the bill of the Common Loon and had a stockier appearance. [...] Common Loon eliminated above. Red-throated Loon eliminated by the dark back, neck pattern, and bill size and shape. | The original documentation form event lasted from 11:06:00/11:45:00.

The long, thin bill eliminates Dovekie, Ancient Murrelet, and all of the auklets. 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 Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: On the basis of the dark hood, size, and dark gray mantle, all gulls except for Laughing and Franklin's gulls can be removed from consideration. I will admit that I was skeptical that a Laughing Gull could show up in Iowa on such an early spring date; most interior records are from May-June. But, given the evidence, I am convinced that this bird was indeed a Laughing Gull. The size of this bird, nearly that of a ring-billed gull, favors Laughing Gull. The bill shape and size, length of the legs, wing pattern, and extent of the eye crescents also favor Laughing Gull. An adult Franklin's Gull can be eliminated by the lack of a white bar separating the gray inner wing from the black wingtip. One year-old Franklin's Gulls, however, may show a wing pattern like that of this bird. But, according to Kaufman (1990), such a Franklin's Gull should show some white flecks on the hood, and would be most likely encountered in late spring and summer. | The original documentation form event lasted from 10:48:00/11:34:00 and 12:26:00/13:20:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. Other observers include Maridel Jackson. | Elimination of similar species: The only species this bird could have been confused with was Horned Grebe. The combination of head shape, smaller, thinner bill, darker foreneck and cheek, and white 'crescent' mark on cheek eliminated Horned Grebe in basic plumage. | The original documentation form event lasted from 09:14:00/10:05:00.
