Occurrence Remarks |
The documentation form by Stephen J. Dinsmore is the only one submitted and forms the basis of this record. | Elimination of similar species: The bird was clearly one of the "hooded" gulls. The combination of size, mantle color, and upperwing pattern eliminates all of the hooded gulls except for Franklin's Gull. The larger size, less obvious white eye crescents, larger and longer bill, and extensively dark tips to the underwings eliminated Franklin's Gull. | The original documentation form event lasted from 12:45:00/13:10:00. |

Event Remarks |
Viewing Conditions: Viewing conditions were excellent with the sun overhead. Estimated viewing distance was initially 100 meters, but I later approached to within 50 meters. I used a 20-60x spotting scope and 10x42 binoculars. |
