The first is to use a thin rope, make a good kind of knot that can be tightened more and more tightly, and then put the pigeon's head into the set, hanging in the air on the staircase frame, a few minutes later, take down the pigeon can be.
The second, with the big mother finger and forefinger tightly inward pinch pigeons under the wings of the two ribs, 1 minute or so, you can kill pigeons.
These are the two common ways I kill pigeons, simple and practical not bloody.
I don't know if these two methods, can help you.
I am foraging for fun with a way, a love of life, like to communicate with people old boy.
