Had one in the garden for a couple of years. Hours of fun watching it and the dog go at it. Not so funny when you forgot to keep an eye on him. They never swoop when they know you are looking at them.
It was very wary of the dog who has reactions as quick him. He donated a few feathers to the cause on a regular basis. Once he must have lost a couple of flight feathers and failed clear the fence. I had to stop the dog before she ended the game permanently. A few days later the bastard re-payed my kindness and put a hole in the top of my wife’s head that bleed as only a head wound can.
There is one half a mile away that drew blood from my earlobe last weekend. Its only doing what its nature demands but boy are they pain at times.
