I worked with a guy in grad school who had falcons, and CR is bang on the money. The most telling part is that you have to come to an "understanding" with the falcon/hawk/whatever raptor you have. It will always KNOW it is the boss, but it will obey you if you are able to dominate it.
I don't mean physically beating it, domination (in those days, may be different now) means staying up and keeping it awake until it can no longer function and sleep is mandatory - for it. You don't count until you stay up longer than the bird. It may take 48 hours, it may take more, but you have to be awake the whole time the bird is.
Find an active falconer and listen to what they say.
