Subject: [obol] Re: Apparent Black-tailed Gull in Oregon

I’d like to amend my last post and say that a 3rd cycle WESTERN GULL can
look very similar to the pictures of the bird I just shared. In my
excitement I overlooked this fact. And there’s Occam’s Razor and what not.
I’m curious to hear what those with experience with BTGU have to say about
this bird.
