Pacific Northwest Gulls & Terns
Slaty-backed Gull ?
Slaty-backed Gull at the pellet plant, Sauvie Island.........February,
1998.
Is this an example of the Slaty-backed Gull seen at the pellet
plant on Sauvie Island? It was definitely darker on the back than all the other
gulls that were there. The "experts" who were busy watching it seemed to think
that it was, but I guess I'm not convinced. It looks a lot like a dark Western
Gull to me. What are your thoughts?
