| Occurrence Remarks |
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. |
