A selection of 1 cy Thayer's Gulls, Half Moon Bay, California, 14 Dec 28

This post shows a selection of subtly different Thayer's Gulls. Some show the accepted phenotypic characters of this taxon, but others (e.g. the second bird) would be rather difficult to identify with 100% confidence out of range.

Hi, you may be interested in a site I have created called Gulls on Film which aims to bring together videos of all the Gull Species from around the world, follow my profile and you'll find it.
I have taken the liberty of adding a link for your site, hope that's ok.
