Occurrence Remarks The documentation form by Barb L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: Similar to most of the other large immature gulls of the world. Mantle too light for Black-backed group. Wingtips, even in their folded condition, too dark for Glaucous, Glaucous-winged, etc. that leaves a whole mess of light-mouthed large gulls with dark wing tips. Description seems to match young Herring Gull (second summer ?) well enough. Eye color would probably be becoming pale in a Herring of this plumage, but perhaps not, + it might not show at the distance. I have trouble eliminating California Gull, but it is even harder to support that species.

Event Remarks Viewing Conditions: 20x scope. I was on road at Settling ponds + it was east of me, on 'beach', near water's edge.
