The training of a hawk is a work requiring great patience and skill, the natural wildness and intractable nature of the birds being very difficult to overcome. When a hawk suffers itself to be hooded and unhooded quietly, and will come to the trainer's hand to receive food, its education is considered far advanced, and the work of accustoming it to the lure may be proceeded with. The lure may be a piece of leather or wood, covered with the wings and feathers of a bird, and with a cord attached. The falcon is fed from it, and is recalled from flight by the falconer swinging the lure round his head with a peculiar cry. When the bird has been taught to obey the lure, it is next practised in the art of seizing its game, being initiated with prey fastened to a peg, and flown later at free game.
