| Occurrence Remarks |
The documentation form by Steve Dinsmore is the only one submitted and forms the basis of this record. Other observers include Bery Engebretsen and Jim Sinclair. | Elimination of similar species: The dark color and white patches on the wings eliminates all larids except jaegers. The noticeable amount of white on the wing, visible on the underside of the wing, eliminates Long-tailed Jaeger. The small size compared to a Ring-billed Gull, less prominent white on the wing, smaller bill size, and more rapid wing strokes eliminates Pomarine Jaeger. | The original documentation form event lasted from 16:46:00/17:14:00 on September 29, 1988 and 10:15:00/10:35:00 on September 30, 1988. |

Viewing Conditions: Viewing conditions were very good with the sun behind me. Estimated viewing distance was 200 yards on 29 Sep, and as close as 100 yards from my boat on 30 Sep. I used a Buschnell 20-45x spotting scope and Bausch and Lomb 8x40 binoculars. |
