I've recently added some photos to my gull photo
archive website that may be of interest to
Tweeters:
1) a Gl-W/hybrid vs. Thayer's page
2) improved pics of Western Gulls with very pale
eyes-- of some interest in light of the apparent
wymani Western Gull w/ the Slaty-backed in Tacoma
3) a quiz bird which really baffled me in Tacoma once.

The site is:

I'm not on Tweeters, so respond directly. thanks,

Steve Hampton
