Occurrence Remarks |
The documentation form by Mark Proescholdt forms the basis of this record. Other documentation forms by Ann Johnson, Jim Fuller, Tanya E. Bray, Barbara L. Wilson, and Randall Pinkston were submitted. Other observers include Ross Silcock, Tim Schantz, Eugene Armstrong, Eloise Armstrong, and many unidentified other observers. | Elimination of similar species: A Franklin's Gull juvenile or first-winter bird has a clear-cut blackish half-hood, a smaller bill, smaller size, and a white forehead. A juvenile Mew gull is much darker, has a thin bill, and light grayish legs. Juvenile Herring and California Gulls are much larger - larger than Ring-Billed Gulls - and lack the bright white at the base of the tail. | The original documentation form event lasted from approximately 09:00:00/09:15:00 and 11:00:00/12:10:00. |
