Glaucous Gull L.hyperboreus  and some Hybrids
28th January 2002 Choshi Chiba Japan

2nd winter Vega-sized hybrid.
1st winter Hybrid, GlaucousXGlaucous-winged? This looks like almost Glaucous Gull from a distance. But it has some grey-brown tones in its primary tips. And the neck and breast show  uniform greyish tones like Glaucous-winged Gull, and lack buffy hemp-like tones of typical Glaucous Gulls.
The tail looks more uniform than that of normal  Glaucous Gulls.
A very large 2nd winter Glaucous Gull.
Another 2nd winter, smaller than the upper bird. The primaries include slight grey brown, so Hybrid?
