Occurrence Remarks |
The documentation form by Raymond Cummins is the only one submitted and forms the basis of this record. | Elimination of similar species: Of the medium sized Gulls only Ring-billed, Franklin's, and Mew Gulls have similar juvenile plumages. The direct size comparison, seen gull being smaller, bill shape and dark color, and lack of white in head eliminates Ring-billed Gull. Mew Gull is eliminated by long dark bill, Ring-billed like jist of bird in flight, and uniform overall color. The long down turned bill and the total improbability of a juvenile Franklin's being in southern Iowa on this date. | The original documentation form event lasted from 10:19:00/10:30:30 on June 4, 1991 and 09:30:00/09:35:00 on June 5, 1991. |
