The documentation form by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: The body and bill structure eliminated all but hooded gulls and the brown plumage indicated a first year bird. Size close to Ring-billed, in addition to plumage already described, eliminated some of the smaller hooded gulls. The most likely candidate for confusion would be the Franklin's Gull. Juvenile Franklin's shows a hooded pattern early in development rather than a brown wash on the head. Franklin's tail band would also be incomplete with white feathers showing on the outer edge. It would also show fewer dark primaries, with the inner flight feathers more approximating the mantle and inner wing color. No other small gull has this characteristic. | The original documentation form event lasted from 11:45:00/12:10:00 and 15:30:00/14:00:00 [sic].

A juvenile Mew gull is much darker, has a thin bill, and light grayish legs. Juvenile Herring and California Gulls are much larger - larger than Ring-Billed Gulls - and lack the bright white at the base of the tail. | The original documentation form event lasted from approximately 09:00:00/09:15:00 and 11:00:00/12:10:00.

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 Thomas H. Kent is the only one submitted and forms the basis of this record. Other observers include Louise Augustine and Dick Tetrault. | Elimination of similar species: The juvenile bird is distinctive and I was able to pick it out quickly. When we first saw the second-year bird, we considered both Franklin's and Laughing gulls. A juvenile or first-winter Franklin's would not have uniform gray in the wing coverts. A second-summer or second-winter Franklin's Gull would not have a full tail band. The bill shape also favors Laughing Gull. The bird appears to be in second-winter plumage, except for the tail band which fits better with first-summer plumage. I was impressed with the soft grayness of the bird and its similarity the birds I photographed recently in North Carolina. | The original documentation form event lasted from 09:30:00/11:15:00.

|
The documentation form by Pam Allen is the earliest and the one that forms the basis of this record. Another documentation form by Peter Ernzen was submitted later. Other observers include Reid Allen, Rob Thelen, and Joe Clark. | Elimination of similar species: See above description. [...] It was about one-third the size of a Kildeer, with a short, thin pointed black bill (longer, however, than a Piping Plover's stubbier short bill). [...] Also conspicuous was the black patch which was located just at the top of the 'shoulder' where the wing joined the body and extending a little ways toward the mid-breast area (but nowhere extending as far as the complete or semi-complete breastband common on the Piping Plover). The legs and feet were a dull dark slate grey (with no hint of the orange/pink coloration indicative of a Piping Plover). | The original documentation form event lasted from 13:10:00/13:20:00 and 14:00:00/14:15:00.
