This is fairly esoteric, mostly for the real gull aficionados, but I've
just put on the web some photos of gull wings from our collection,
including Herring, Herring x Glaucous-winged, Glaucous-winged,
Glaucous-winged x Western, and Western. More variation in other species is
to follow. There are also lots of other wing photos there:

There is a fabulous photo site of Japanese gulls, including many, many
photos (wings with whole birds attached) at:

Happy gulling!
