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.

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.

The documentation form by Joe Schaufenbuel is the only one submitted and forms the basis of this record. Other observers include Alan Branhagen. | Elimination of similar species: Bald Eagle; my bird was not mottled as an immature Bald is, also my bird had totally dark under wing coverts. The distinct demarcation of light to dark on my bird also was rather un-Baldlike. Since an on the spot size comparison was made with a buteo, and the latter was found to be much smaller, I feel safe to say all others of this genus can be rolled out. | The original documentation form event lasted from 08:15:00/08:25:00.

General: border between an extensive tract of riverbottom forest and a half-mile stretch of corn and soybean fields (with large patches of unharvested beans). At the north edge of the fields was a road, followed by a wooded ridge. Specific: Perched at the edge of a narrow screen of trees that extended out from the forest, between two fields. [drawing]
|
The documentation form by Michael Newlon is the only one submitted and forms the basis of this record. Other observers include Richard DeCoster. | Elimination of similar species: The three species with which confusion is most likely are the bald eagle (imm) and red-tailed and rough-legged hawks (dark-phase). Several points rule out these species. (1) Size: the body length of the bird was 2&1/2-3 times that of a crow that perched in the same tree; the two hawks are not nearly this large. (2) tail pattern: imm. bald eagles sometimes show tails that are darker at the tip than at the base, but all such individuals that I have seen have had a gradual transition from dark to light, rather than the sharp boundary that this bird showed. Adult melanistic redtails usually have red tails; imm birds should show dark tails crossed by darker bands. (3) Wing pattern: imm bald eagles have white in the wing, but this is usually in the wing-lining rather than the primaries and secondaries; dark-phase rough-legs usually have the primaries and secondaries entirely white. (4) build: bald eagle has longer neck, and more massive head and bill, than golden; this bird had the general proportions of a buteo. | The original documentation form event lasted from 09:00:00/09:30:00.
