cloud mountains

I've just got back from a walk. It was chillier than it looked! But while I was out the clouds piled themselves into lovely mountains so I just had to blip. Lots of people on Twitter are getting themselves terribly excited about the rare gulls they've spotted. I have to admit I haven't seen them yet! One of them apparently looks rather like the juveniles we have massing around the river mouth but lighter. I can't tell the difference!
