Hi Keith,

Just took a quick look at your photos and I'm a little confused about
what suggests GLGU x HEGU? The primaries don't look that dark and I
don't really see anything to argue against Glaucous, except possibly
size which maybe suggests Iceland rather than hybrid with Herring. That
said it seems bulky, the bill looks heavy, eye looks big and more
centrally located, and Pp extension looks short for Iceland. My first
impression is of a smallish Glaucous Gull. I'm curious to here what
others think...
