Olympic Gull glaucescens x occildentalis adult, February 16 2009, Portland, Oregon. Picture: Lyn Topinka.Purple orbital ring and extensive speckling in iris ( >75%). Medium grey primary pigmentation, obviously darker than upperparts may be indication for occidentalis influences. Upperparts too dark for pure Glaucous-winged. Also primaries too dark, but not black as in occidentalis. Pure occidentalis would not show head mottling (at all in winter). |
