The following link is an excellent web site to compare the features of
L.h.barrvianus Glaucous Gull with Iceland. Honestly, I would find it very
difficult to pick out one from the other by the photos, but it does show
how dainty and attenuated the barrovianus can appear to be, leaving us
with a combination of lesser features to try to ID individual birds. In
many cases I think that a firm ID may be tenuous at best.

Having not seen 'Bob', I have no opinion as to race, or even the species
of this particular bird. That said, a review of the various web sites
devoted exclusively to gulls can give one an idea of how difficult gull
identification is in general. In this particular case of 'Bob' the ID
quandries are even more complicated when trying to pin down a definitive
ID. A review of these sites can offer us great opportunities to delve into
these difficult ID dilemmas and learn something.

Try this link for Gulls (Japanese site):
