So this may be a stupid question, but has anyone thought of modifying the carrying behavior instead of trying to eliminate it?

What if the behavior could be modified so that instead of carrying quarry to a tree somewhere, the bird carried it back to the falconer?

I don't mean this as a way to be lazy...but if there was a way to do this, it would open up birds like ospreys as possible falconry hawks.

And as an animal behaviorist, I just have to ask if anyone has thought of this idea, tried it, or planned out a training program for it? I find it hard to imagine it hasn't come up before...
