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: Franklin's Gull is the only species this bird was likely to be confused with. The larger size, longer, more pointed wings, lack of white color in the primaries, longer, larger bill, dark legs and bill, and gray wash on nape (rather than a more distinct half-hood) are sufficient to eliminate Franklin's Gull. | The original documentation form event lasted from 16:05:00/16:30:00 on July 8, 1994 and 06:15:00/06:28:00 on July 9, 1994.

|
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 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.

The documentation form by Babs & Loren Padelford is the only one submitted and forms the basis of this record. | Elimination of similar species: At rest, the bird had a very slender and streamlined appearance, not stocky like that of a Franklin's Gull. 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.

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.

The documentation form by Richard Hollis is the only one submitted and forms the basis of this record. Potential other observer includes Thomas H. 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.

Size, bill size, leg color and lack of white on primaries eliminated Franklin's Gulls. Common Black-headed Gulls were eliminated by the black, not brown, hood, black legs and lack of white on dorsal wing. Sabine's was eliminated by the bill color, size and lack of white on dorsal wing. | The original documentation form event lasted from approximately 08:00:00/08:10:00.

The documentation form by Mark Brogie and Peter P. Wickham forms the basis of this record. Another documentation form by Paul Martsching was submitted. Another observer includes Steve Dinsmore. | Elimination of similar species: [...] The bird was in the company of several Herring Gulls (Larus argentatus) and three subadult Glaucous Gulls (Larus hyperboreus). Two of the Glaucous Gulls were light plumaged birds lacking a gray mantle and, since eye color was not noted, may have been either first or early second winter birds. The third Glaucous was quite buffy and was undoubtably [sic] a first winter bird. The Iceland Gull was first observed being chased by a light-phased Glaucous and was distinctly smaller and lighter colored. It also flew with a faster wingbeat and had a more buoyant flight than that of the larger bird. Glaucous Gulls were also observed chasing Herring Gulls but at no time was intraspecific chasing observed. During several instances two Glaucous Gulls were observed resting on the water or sitting on the ice together, but the Iceland always remained isolated from these birds. At one point the Iceland Gull circled overhead at a distance of approximately 40 yards in the company of a light-phased Glaucous and an immature Herring Gull, and characteristics between the species were well noted. The plumage of the Iceland was wholly white with a faint buffy tinge, yet distinctly whiter than the Glaucous Gull. The size difference between the Glaucous and the other two species was apparent as the Iceland and Herring were of approximately equal size. The head and bill of the Iceland Gull appeared less robust in shape than the Glaucous although both species had a bicolored bill with a flesh colored base and dark tip. [...] The brown barring of the undertail coverts of the Iceland appeared heavier and more noticable [sic] than in its white-winged congeneric counterpart, and contrasted particularly with the whitish tail. | The original documentation form event lasted for approximately twenty minutes.

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 Mark Proescholdt forms the basis of this record. Other documentation forms by Michael D. Overton and Stephen J. Dinsmore were submitted. Other observers include Kay Niyo, Curt Nelson, Jan Walter, Chris Wood, and Jim Sandrock. | Elimination of similar species: [...] We saw this gull twice in our viewing time and debated if it was an adult Kumlien's Iceland Gull or an adult Thayer's Gull. 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.
