That's what I thought. The wingspan is big and the deer does'nt look too small. I think it would be illegal here in the states, but one heck of a video.
Falconry is legal in some states. I had a friend once that did it. He lived in Texas at that time, but I don't know which states permit it. Since so very few in the US do it, I doubt that it would pose much of a threat to the wildlife populations. The guy I knew used small hawks that caught rabbits, etc., NOT DEER!
