Having dealt very efficiently with my first gull from Choshi, I thought I would try my luck with this second one. I posted this on Surfbirds and it seemed to stump everyone.

I took the photo on 25 January 2011 at Choshi in Japan (and it is the only one I have of the bird). My hunch is that it *might* be a small (female?) first winter Slaty-backed as the plumage tones (in particular the base colour, tertials and primary colouration) and rather short-winged profile seem to fit. However, it does not look typical in terms of bulk for this species, and the rounded head is troubling me, so I may be off-beam.

From looking at images on the excellent Japanese Gull site, I don't think it is a Vega or Glaucous-winged but can't seem to find a good fit.

Any ideas?

Thanks again and I promise this is the last one (for a while at least!).

I´d also go for female SBG. As with most gulls I think it´s expected that some individuals are particularly petite as well as some can be very brute.

As you say Terry you - it came out as nothing sure at all on the Surfbirds forum. A pitty you didn´t have some more pic!
Maybe after all it might be a small female Slaty-backed. I certainly can´t come up with something else, except perhaps a hybrid of some sort, which is the impossible road in this case I gather.

Hi Terry.

The two links work for me Terry. Try this instead and click on 'Gulls on Hokkaido in English'
