In reply to Mike Conlon:
I think it might be slim pickings, I'm afraid. There's a thing called Bideford Ridge on the east side somewhere. I have the vague memory of seeing a decent-looking picture of it somewhere at some point. Although either we didn't find it, or it's in reality absolute bobbins. Still, it's a day out where you won't be strafed by nesting great black-backed gulls, which has something to be said for it.
The Constable isn't bird-banned, is it? There's a reasonably amenable way up that.
