| Occurrence Remarks |
The documentation form by Rick Wright is the only one submitted and forms the basis of this record. Other observers include Ken Strom and Marie Strom. | Elimination of similar species: [...] The different mantle colorations of the herring and ring-billed gulls were distinguishable. [...] The presence of other gull species convinced me that I had accurately judged the mantle color of this bird; I was able to compare it with 3 other species, as well as Caspian terns. The size and bill size rule out great Black-backed, the only dark-backed gull with which I am familiar. Although western gull would show a similar upper-wing pattern, I suspect that it too would appear heavy-billed (and would not have yellow feet). Yellow-footed gull is also large and deep-billed, and is probably less likely than lesser black-backed in Iowa. | The original documentation form event occurred around 13:30:00/13:30:30. |

| Event Remarks |
Viewing Conditions: Optical equipment: 8.5x binoculars, 22x scope Light: Strong, from behind. Not so much glare as to render imperceptible the difference in mantle colors of the herring and ring-billed gulls also present. [...] The bird in question flew in from the south, perched on the ash for less than three seconds, and took off for the north. Total time of observation was probably less than 30 seconds, including time during which the bird was too distant for any identification beyond genus. |
