| Occurrence Remarks |
The documentation form by Dennis Thompson is the only one submitted and forms the basis of this record. | Elimination of similar species: Franklin's gull - bird had a completely different build. I had the advantage of a direct comparison with ring-billed. This bird was smaller, but still larger than a Franklin's. I would say it was half-way between a Ring-bill + Franklin's in size. White was almost non existent in the wingtips, both at rest + in flight. The most obvious difference was the structure of the bird. As soon as I saw it, I knew it wasn't a Franklin's. The long neck, size, long legs, long bill, + "pot-bellied" look caught my eye immediately. I guess another way to describe it was upright-looking. | The original documentation form event lasted from 06:30:00/06:35:00. |
