Falcons are generally flown single at rooks, except at the time of entering them with a make-hawk. In a double flight I think that the rook is as a rule a bit overmatched, that is, if the hawks are in proper fettle. But for entering a backward hawk, or encouraging one which does not take kindly to this flight, it is very useful to use a make-hawk, that is to say, one which is already keen in the cause. Most hawks are very strongly influenced by example; and a young eyess particularly, recognising as she does the superior style of a haggard or passager, will readily imitate her, and join in a chase upon which she sees that the other has embarked. A double flight is very pretty, and very effective. The way in which the two hawks assist one another, waiting each for her turn to stoop, and making her plans so as to profit by the action of her comrade for increasing the force of her own strokes, is interesting even to the most careless observer of animal life. But the double flight is better reserved for such more arduous undertakings as the pursuit of kites, herons, and gulls. A few words will be said in a later chapter about these quarry and the sport they afford. But in all the main particulars it resembles that which has been here described. The rook flight is at once the commonest and the most typical form of sport when the hawks are flown out of the hood; and he who has successfully trained a peregrine to this business should have no great difficulty in making any other of the large long-winged hawks to such other quarry.
