One thing I've noticed is everything fights for the best spot. I was on the west cliffs and noticed a pair of Razorbills in a Kittiwake nest. The Kittiwakes were none to pleased and after an initially. stubborn defence a Kittie got hold of a Razor and pull it off the ledge. The pair plummeted 50 metres to the sea. Both birds appeared unharmed and the Kittiwake came back to dispatch the other bird with a similar lack of dignity.
