The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The only species of confusion was Franklin's Gull. The larger size, wing pattern, tail pattern, and bill size and shape all eliminated Franklin's Gull, many of which were nearby for comparisons. | The original documentation form event lasted from 09:40:00/10:32:00 and 13:45:00/14:20:00.

White, Gerald
|
Townsend's Warbler
|
Wildcat Den State Park
|
[...] At Wild Cat Den State Park in a small area of bottom land of deciduous woods on May 12, 1988 at 7:20 AM, for aproximatly [sic] 45 seconds.
|
|
The documentation form by Gerald White is the only one submitted and forms the basis of this record. | Elimination of similar species: [...] When the first look at the head I thought of a possible Blackburnian but when I saw the neck I knew I had a new bird for myself. The most striking features being the head and throat markings. [...] I then checked the rest of the birds listed and made the summation that I had seen the Townsend's. That evening when I returned from work I checked my Golden, Peterson, N.G.S. and Audubon Master Guide for their accounts of the Townsend's and similar species. I eliminated the following; Hermit Warbler - no cheek patch: Blackburnian - dosn't [sic] have a black throat: Black-throated Green - has solid back color and cheek patch not as bold, no black cap. Of the references mentioned, the N.G.S. has the most accurate illustration of the birds head but I can't verify that the bird I saw did or didn't have yellow under the eye. | The original documentation form event lasted from approximately 07:20:00/07:20:45.

The yellow eyes of the Great Gray Owl eliminated the possibility of a Barred Owl which has dark eyes. Also, size would eliminate the Barred Owl. The Great Gray Owl looked almost twice as large as a Barred Owl. | The original documentation form event lasted from 14:52:00/16:09:00.

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 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 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 Bery Engebretsen is the only one submitted and forms the basis of this record. Other observers include Eugene Armstrong and Eloise Armstrong. | Elimination of similar species: Bird flew & sat on ground next to Franklin's Gulls, and Bonaparte's gulls. Did not have white wedge of Bonapartes, Blackheaded or Sabine's Gull's. The other black-headed gull, the Little Gull, has no black at all on wing tips. See above for comparison to Franklin's.

Eye ring smaller, less conspicuous, again, than adjacent Franklins. | The original documentation form event lasted from 09:20:00/09:40:00.

The documentation form by Thomas H. Kent is the earliest and the one that forms the basis of this record.

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.

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.
