Glaucous Gull

There have been fewer of these bruisers around this winter than usual. There has been one however regularly at Howmore on South Uist.
I actually took this photo on Thursday but only loaded it up today and on examination I think in fact it is a different bird to the one being regularly seen. This one has a dark eye and a pretty dull bill whilst the one I've seen images of has an almost bubble gum pink bill and a paler eye, indicative of a second winter bird.
