Greater (or lesser) gull.

As the wet and huddled shoppers were slowly enveloped by the encroaching darkness, the realisation that there would be no chance of a WidWed shoppers pic. slowly dawned. Undeterred, the resourceful blipper produces this pic. of a near adult greater or lesser black backed gull (the experts are undecided) taken this morning before the rain arrived. I feel like a Blue Peter presenter who says "and here's one I prepared earlier"!
The extra is "Hey you, get offa my rail!"
