Adult Gulls - Camano Washington State USA (1 Viewer)

Fandango739

United States
All seen last week during cold and dreary weather at a west side beach. The lighting was tricky, potentially altering the appearance / darkness of plumage.

The bill extension on the first gull is actually a shell the bird is holding.

Many thanks!

They use to wake me up in the mornings when I lived on Alkia Beach. ( I loved it. )

In West Port WA I had one come in my hotel room. They're huge.
 
The darker backed birds might be pure Western Gull, but all may be Olympic Gulls: Western x Glaucous-winged hybrids.
 
Fandango, that's indeed still a controversial ID matter with Glaucous-winged. While primary tips are clearly a bit darker than upperside (mantle) a few Gull people would consider this as in line with pure GLWG (e.g. Peter Adriaens, one of world's top gullers), others don't. You might call no 1 an 'almost pure' GLWG or just put it into the Olympic box, as most would. Fact is that most GLWG breeding on the Pacific south of Alaska (where no Western Gulls are) show on average slightly darker wingtips than those from Alaska and Kamtchatka. It's merely a matter of accepting these more southern breeders as pure or not.
