On his eleventh day of hack, Jubilee, the male merlin already referred to, was sitting with his two sisters and one brother in the branches of a fallen tree in the hack field, under which I was seated, garnishing the lures for their delectation a little later on. Suddenly the little hawk started at his best pace right down the field. I supposed that he was after some blackbird in the far hedge. But before reaching it he turned, and began mounting as he came back towards me. I looked round, and for the first time saw that a wild kestrel had come over into the field, and was dodging the stoops made at him by the remaining merlins. Now this kestrel was one of a brood which had been flying at hack under their parents' care in a neighbouring field. They were already strong on the wing before the merlins were turned out; and I had been rather fearing, when I discovered their near presence, that they might do the young merlins a bad turn. No encounter had, however, as yet occurred between the two families. The kestrel had at first little difficulty in eluding the stoops of the three merlins, who seemed not much in earnest. But when Jubilee came over, at some height in the air, there was a different tale to tell. With his first stoop he made the wild hawk cry out; at the second he almost feathered him, and made him shuffle off to the orchard near at hand, where, swirling round the tree-trunks, he threw out his assailant, and made off to a tall elm. Here, no doubt, he fancied he was safe, especially as the other hawks, on Jubilee's appearance, tailed off. But not a bit of it. Throwing himself well up above the elm, the little jack dashed down at the enemy in the tree, dislodged him, and with a back-handed stoop drove him down to the ground, hunted him all across a meadow, grazing him at every shot he made, and lost him in a big orchard farther on. The pace of the wild hawk was very poor in comparison with that of this half-tame lure-hacked merlin. It seemed as if the latter could have given him ten yards in a hundred. In straight-ahead flying, in mounting, and in throwing up, the kestrel was completely outpaced. Yet before now trained merlins, as I have heard tell, have been outflown and chased by a wild kestrel. I should not like, and do not ever expect, to own such a trained merlin.
