The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. Other observers include Tanya Bray, Babs Padelford, and Loren Padelford. | Elimination of similar species: Differs from Franklin's Gull only in lack of white line between black primaries + gray mantle. I saw one Franklin's this spring with a very narrow white band in the primaries. If this isn't a Laughing Gull, it's an aberrant Franklin's. It seemed to be in a very neat breeding plumage, not a young bird. | The original documentation form event occurred in the afternoon for around two minutes.

Kent. | Elimination of similar species: [...] I looked at my field guides + realized that I was not sure if I could distinguish Franklins from Laughing Gulls in their last summer plummage [sic] before becoming adults. I am not sure of the identification. At present I lean toward Laughing due to 1. lack of obvious white on wings 2. Size of dark patches @ wing tips 3. Dark color of mantle 4. The white tail rules out all the younger birds. | The original documentation form event lasted from approximately 10:00:00/10:05:00.

The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. | Elimination of similar species: Franklin's gull - bird had a completely different build. I had the advantage of a direct comparison with ring-billed. This bird was smaller, but still larger than a Franklin's. I would say it was half-way between a Ring-bill + Franklin's in size. White was almost non existent in the wingtips, both at rest + in flight. The most obvious difference was the structure of the bird. As soon as I saw it, I knew it wasn't a Franklin's. The long neck, size, long legs, long bill, + "pot-bellied" look caught my eye immediately. I guess another way to describe it was upright-looking. | The original documentation form event lasted from 06:30:00/06:35:00.

The head had no trace of a dark hood. The head was the same color as the rest of the body except for lighter areas around bill, on forehead and top of the head. The bill seemed longer and more curved than a Franklin's, but difficult to say with no Franklin's for comparison. | The original documentation form event lasted from 10:15:00/11:05:00.

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 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 Tanya Bray forms the basis of this record. Another documentation form by Ross Silcock was submitted. Other observers include Babs and Loren Padelford. | Elimination of similar species: This bird differed from Franklin's Gull in the following ways: 1. Less extensive black on head. Eye coverts were not immediately noticable [sic] due to white cheek area. 2. Longer legs, more upright posture, and generally a very long, slender bird. 3. In flight, the bird had long slender wings with completely dark primaries; no white dividing the tips of the outer primaries from the rest of wing, and no white tips to outer primaries. Underside of primaries as described above. 4. Bill was long, curved and slightly swollen and hooked at tip. | The original documentation form event lasted from around 07:35:00/07:36:00, 08:45:00, 12:15:00, and 18:30:00.

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 Raymond Cummins is the only one submitted and forms the basis of this record. | Elimination of similar species: Of the medium sized Gulls only Ring-billed, Franklin's, and Mew Gulls have similar juvenile plumages. The direct size comparison, seen gull being smaller, bill shape and dark color, and lack of white in head eliminates Ring-billed Gull. Mew Gull is eliminated by long dark bill, Ring-billed like jist of bird in flight, and uniform overall color. The long down turned bill and the total improbability of a juvenile Franklin's being in southern Iowa on this date. | The original documentation form event lasted from 10:19:00/10:30:30 on June 4, 1991 and 09:30:00/09:35:00 on June 5, 1991.

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].

The documentation form by Ross Silcock is the earliest and the one that forms the basis of this record. Other documentations by Babs and Loren Padelford as well as Paul Lehman were submitted later. | Elimination of similar species: [...] Later it was seen at rest with Ring-billed and Franklin's Gulls, the latter group including a few individuals of the same age as the Laughing Gull, allowing careful comparison. [...] The wings were long and pointed, the overall jizz of the bird more attenuated than a Franklin's. [...] There was a grayish-black wash over the crown and nape, slightly intensified in the upper nuchal area, and a paler grayish wash on the flanks in the area below the bend of the wing, imparting a "dirtier" look to the underparts than on same-age Franklin's Gulls (seen when at rest). At rest, the black primaries extended well past the tail, a feature compared easily with nearby Franklin's, and there were no small white crescents in the primaries of the Laughing Gull, a feature easily seen in same-age Franklin's nearby. The Laughing Gull was almost as big as the Ringbills near it, while it appeared significantly larger than the adjacent Franklin's. | The original documentation form event lasted from 11:30:00/11:40:00.

The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The bird was clearly one of the "hooded" gulls. The combination of size, mantle color, and upperwing pattern eliminates all of the hooded gulls except for Franklin's Gull. The larger size, less obvious white eye crescents, larger and longer bill, and extensively dark tips to the underwings eliminated Franklin's Gull. | The original documentation form event lasted from 12:45:00/13:10:00.
