Falconry has become a complicated art. Very possibly the good folk in St. Aliquis will have their bodies physicked or bled by physicians much less skillful in treating human ills than Conon's falconers are in treating birds. To climb high trees or crags and steal the young hawk out of the nest is itself no trifling undertaking.[17] Then the prizes must be raised to maturity, taught to obey whistles and calls, and to learn instantly to do the bidding of the master. In the baron's mews are more than a score of birds; gerfalcons, saker hawks, lanners, merlins, and little sparrow hawks squawk, peck, and squabble along with huge goshawks. The male birds are generally smaller than the female, and the latter are reserved for striking the swiftest game, such as herons. Some birds will return of their own accord to the hand of the master after taking game, but many, including all sparrow hawks, have to be enticed back by means of a lure of red cloth shaped like a bird. The falconer swings his lure by a string, and whistles, and, since the falcon is accustomed to find a bit of meat attached to the lure, he will fly down promptly and thus be secured. Conon's head falconer is only a villein, but he is such an expert that recently the Count of Champagne offered a hundred Paris livres for him. This important personage is himself the son of a falconer, for the science runs in families. He is a man of shrewd knowledge and a real wizard at breaking in young birds, teaching them to strike dummies and decoys, to remain contented in their cages or hooded on their perches, and yet not lose their hunting spirit. He has precise methods of feeding--so much meat, preferably poultry, and so much of vegetables, preferably fresh fruit. He takes long counsel with Conon how a recalcitrant goshawk can be induced to sit quietly on the baron's fist. He also teaches young François to carry his little sparrow hawk so it will not be incommoded by any horse motion or be beaten upon unpleasantly by the wind, and how to adjust its hood.
