| Occurrence Remarks |
The documentation form by Jim Fuller is the only one submitted and forms the basis of this record. Other observers include Ann Johnson, Chuck Fuller, and Jane Fuller. | Elimination of similar species: Herring Gull (first winter) compared above. [...] I first saw this bird flying, and the underwing was translucent throughout the primaries to the end of the wing (Herring Gull had dark outer primaries, although most also had a lighter window type area medial to this dark area). The bird was about the same size or a little smaller than the Herrings. The upperwing in flight was much lighter in the primaries than the first winter herrings. [...] It had a more rounded head than the herrings. [...] It's color was more uniform than the herrings and also lighter- a brownish color. There was a dark smudge around the eye. The feather edging (whitish) provided more contrast with the brown on the back than in the herrings, and the folded tail was brownish, not black. When in flight the tail band was brownish not blackish like the herrings. | The original documentation form event lasted from 13:15:00/13:45:00. |
