| Occurrence Remarks |
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. |
