Occurrence Remarks 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.
