absolutely shat my self the other day when a pheasant tried to fly through the front window. I don't know who got a bigger shock, me or my 9 week old boy who I was feeding at the time.
The last one to do that at my mum's ended up on the dinner table
you could always set up a series of mirrors so it sees loads of reflections and gives up because he's outnumbered (or gets too confused as to who to 'go for' first!)
