Occurrence Remarks The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The size, uniform body and wing color, pale underside of the flight feathers, and tail band eliminates Herring and Glaucous/Iceland gulls, the most likely candidates for confusion. | The original documentation form event lasted from 14:04:00/16:42:00.
Occurrence Status present
Field Number 1989-54
Event Remarks Viewing Conditions: Viewing conditions were very good with the sum [sic] bahind [sic] me. Estimated viewing distance was mostly 150-200 yards, but I was within 10-15 yards on several occasions. I used a Buschnell 20-45x spotting scope and Buschnell 7x35 binoculars.
