Gull ID please

Please help to identify this gull which was seen in Hokkaido on 27 February 2011. Thanks.

Is it a jenvenile Slaty-backed Gull?

The pale iris is unusual for first-winter birds, though I've not seen that many so late in the winter.

Do you have any more shots of this bird?

Geoff the photo is not taken in Hong Kong. May be useful for the identification?

I realise it was taken in northern Japan. Any other photos of the bird, particularly perched, would be useful.

Geoff,

I totally took 6 shots of this gull, at 06:20:07 Japan local time, the pictures of which are reproduced herebelow for your reference -
Sorry for the noisy background due to high ISO @5,000.

Rounded primary tips together with the pale iris suggest a 2nd cycle (3cy) bird.
Some nice pic but as Geoff mentioned a standing bird would have been nice to see.
