The documentation form by Peter C. Petersen is the only one submitted and forms the basis of this record. Other observers include Ann Barker, Brian Blevins, and Eugene Armstrong. | Elimination of similar species: Great Black-backed Gull - this bird much too small Lesser Black-backed Gull - Too heavily built, tail band very broad, no yellowish colour on legs. Slaty-backed Gull - The biggest problem - I felt this bird was not dark mantled enough was too heavily bodied + too much of a domed forehead. | The original documentation form event lasted from 09:35:00/09:45:00, 10:35:00/11:00:00, 12:40:00/12:52:00 on January 15, 1991 and 09:25:00/09:35:00 on January 16, 1991.

Other observers include Dick Tetrault, Peter Petersen, Ann Barker, Eugene Armstrong, Eloise Armstrong, and Chuck Fuller. | Elimination of similar species: Western gull is the same size as herring gull, as is slaty backed gull and lesser black backed gull is smaller than herring. The very large legs and bill would also speak against lesser black-backed and slaty-backed. | The original documentation form event lasted from 11:05:00/11:40:00 on January 14, 1991 and 07:41:00/07:48:00 and 08:12:00/08:28:00 on January 17, 1991.
