I went to a school of falconry in England. The guy who ran the school had a golden eagle. It's hard to appreciate how really damn big they are until you hold one on your arm. I saw him fly the thing to a lure, too. Pretty awesome based on size. But the Peregrine falcon was a LOT faster.
I had my own Goshawk after I went to that school. Lot of fun. Lot of work. Very impressive to see them fly. Very impressive.
