Oregon. January.

Age: Adult and 1st cycle.

Identification: Beginning with the adult, it has a strong, bright yellow bill. The head pattern is densely smudged, and the primaries are slate-black with distinctive pale underside to the far wing. Every thing about this bird is consistent with a hybrid Glaucous-winged x Western (so-called Olympic Gull). The primaries are too pale for Western, but too dark for Glaucous-winged. The 1st cycle, similarly, has features intermediate between both species, and was identified as a hybrid.
