Olympic Gull (occidentalis x glaucescens) 1st cycle, October 28 2011, Elwha River Mouth, Clallam County, WA, USA. Picture: Steve Mlodinow.See Steve's Flickr photostream. Note the dark mask of a Western Gull and the rather dark plumage overall with more GW Gull like primaries (but with primary tips still too dark for that species). |
