In the past it was, but we now have other devices for falcons to hunt, such as drones and radio-controlled “birds”, which can produce brilliant flights with falcons, arguably better than at live quarry. “Hawks of the fist” like Harris Hawks, Redtailed Buzzards, Goshawks etc., do not produce spectacular flights, so really they are purely for hunting. If you do hunt, it should be remembered that the object of the sport is NOT to catch large amounts of quarry, but to see high quality, fair and sporting flights, whatever species you fly. Quantity is the opposite of quality.
