観察結果の詳細
Rounder head , slimmer bill, much lighter plumage (including primaries) than adjacent HERGs. Primaries were a light dirty grayish color and darker than the tertials, coverts, and mantle. (Having primaries darker than tertials rather than concolor or lighter indicates that the bird is possibly thayeri.) The bill was two toned with a dark anterior section indistinctly separated from its lighter base (as is sometimes the case with first winter birds according to Dunn and Karlson's "Gulls Simplified"). The tail was lightly banded with a "non-solid" brownish band which was visible when the bird was preening. The bill was too slim and not sufficiently sharply bicolored, head too rounded, body too small, and primaries too long for Glaucous Gull. Crummy digiscoped photos taken through small, distant branches included for additional documentation.
