| Occurrence Remarks |
The documentation form by Ray Cummins forms the basis of this record. Other documentation forms by Stephen J. Dinsmore and Jim Dinsmore were submitted. Other observers include Dennis Thompson and Susan B. Grove. | Elimination of similar species: see above [...] The setting gull in direct comparison to the two Bonaparte's was lighter mantled, larger, whiter headed, the bill was longer and heavier, and the bill was reddish black not pure black like the Bonaparte's. In flight the gull had the same upper wing pattern as the Bonaparte's. [...] The underwing was not totally black like the Little Gull. | The original documentation form event lasted from 10:30:00/10:36:00. |
