The documentation form by Steve Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Jim Sinclair, Thomas H. Kent, and Jim Fuller were submitted later. | Elimination of similar species: Ring-billed and Herring gulls are the two most likely species of confusion. Ring-billed Gull never shows this much brown in any plumage, has a dark tail band in immature plumages, has a different wing pattern, and is structurally different from California Gull. Herring Gull is more similar in first-basic plumage, but always shows a pale window on the inner primaries, lacks the double dark bar effect in the innerwing, is larger, and very rarely shows a strongly bicolored bill. | The original documentation form event lasted from 10:55:00/12:24:00.

Other observers include Doug Rose, Roger Rose, and Ken Lowder. | Elimination of similar species: Because of the fairly small size and conspicuous dark spot behind each eye, the bird must have been a Bonaparte's, Little, Common Black-headed, or Ross' gull, or a kittiwake. Separation from Bonaparte's Gull is discussed above. Little Gull eliminated by its smaller size, dark bill, lack of any black color on the upperwing, and uniformly dark underside to the flight feathers. Ross' Gull eliminated by tail shape, bill size and color, and darker underwing. Both kittiwakes eliminated by bill color, lighter mantle color, and differences in wing pattern. | The original documentation form event lasted from 16:17:00/16:42:00.

An immature white-faced would lack the blue facial skin and would likely show some brownish feathers. The color differences were clear-cut and observed under identical viewing condition. | The original documentation form event lasted from 13:30:00/13:40:00, 14:20:00/15:25:00, and, on May 19 from 08:40:00/08:45:00.

If there was any problem with this bird being anything it was a Glaucous Gull of the same age. However the bird was smaller than the Herring Gulls that were on the roost. Long wings will rule out the rare small race of Glaucous Gull. There are not to [sic] many birds that have primaries lighter than the mantle in the sitting bird.

It was an adult Kumlien's Iceland Gull because a Thayer's Gull has much more blackish coloration at the primary tips and more dark coloration at the primary tips than the Kumlien's which has grayish markings on the primary tips and less dark-colored markings at the primary tips overall. Also, a Kumlien's Iceland Gull shows the almost white wing tips like we saw with a little grayish markings on some primary tips. | The original documentation form event lasted from approximately 15:00:00/16:15:00.

The documentation form by Stephen J. Dinsmore is the earliest and the one that forms the basis of this record. Other documentation forms by Thomas H. Kent and Jim Fuller were submitted later. Another observer includes Chuck Fuller. | Elimination of similar species: The three most similar species are Herring, Thayer's, and Glaucous gulls in first-basic plumage. The latter was eliminated by its larger size and longer, heavier, bicolored bill. First-basic Herring Gull is much darker overall with primaries darker than the upperwing coverts, a pale window on the inner primaries, and rectrices that are all black. First-basic Thayer's Gull is the hardest to eliminate. Thayer's always show primaries that are as dark or darker than the rest of the wing. The dark tail band of Thayer's is always darker than the mantle and apparently matches the color of the wingtips (Kaufman 1990). | The original documentation form event lasted from 11:30:00/13:10:00.

The documentation form by Thomas H. Kent forms the basis of this record. Another documentation form by Bob Cecil was submitted. Other observers include John Cecil, Bob Myers, and Maridel Jackson. | Elimination of similar species: The small size, small head and bill, and all dark bill exclude Glaucous Gull. The lack of any dark in the wing or tail exclude Thayer's Gull. | The original documentation form event lasted from approximately 12:30:00/13:00:00.

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.

Other observers include Russ Widner, David Arbour, Reid Allen, Tim Schantz, Jane Fuller, and many unidentified other observers. | Elimination of similar species: The bird was smaller and more brown than the ring-bills of the year. The other features noted above make the juvenile Laughing Gull an easy identification. | The original documentation form event lasted from 07:45:00/08:00:00.
