Well, my DSLR was stolen, but I still have my archives to draw upon.

Steve Layman gave a demonstration at the 2001 California Hawking Club of the sort of results he gets using straight operant conditioning with his falconry birds. Sharp-shinned hawks are accipiters, high-strung and with a reputation for being temperamental. Layman’s technique, though, resulted in this bird paying close attention to him, performing a series of jump-ups and flights to the lure despite being in front of an audience of falconers in a hotel meeting room. At the end of the demonstration, she got her reward. By her expression, she isn’t willing to share.
