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 [sic] in the wing-tips, 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.

The documentation form by Bery Engebretsen is the only one submitted and forms the basis of this record. | Elimination of similar species: I could see both Laughing + Franklin's standing side by side. Laughing were clearly 20-25% larger, as was bill. A more prominent 'gonys' made the bill appear somewhat more hooked. In flight, the wing tips were black + more extensive than Franklins, both above + below. I looked carefully for any trace of white between tip + rest of wing, as well as for any white on the head, and there was none. The eye ring was broken on the front, less so in the back. The Franklin's had a rounder appearance to the head than did the Laughing. In flight, the Laughing's tail was pure white. | The original documentation form event lasted from 08:05:00/08:35:00.

Also, wings were held flatter than what I expect for a Turkey Vulture. Harlan's Hawk: Breast and belly solid in color, no barring on tail, wing shape unlike that of Red-tailed Hawk. Size difference.
