The flight at gulls is so similar to that at rooks, although much more difficult, that I should be tempted to say no more concerning it, were it not that I have been favoured by Mr. St. Quintin, who is the great authority on the subject, with some most interesting details of this sport. There can be no doubt, I think, that of all flights in which peregrines can now be flown out of the hood in England, gull-hawking is the best. It requires a cast of hawks; and these must be of special excellence, and in the height of condition, if any success is hoped for. Tiercels may be used as well as falcons; eyesses as well as passagers; but of course the probabilities of success are less with the smaller and less-experienced hawks. In the case of the herring-gull, indeed, the quarry falls so heavily, when taken, that a small hawk is apt to be badly shaken, and may thus become disgusted with the whole business. Of the three kinds of gull, the largest, the herring-gull, is also the least difficult to take. He makes something of a fight of it on the ground when taken, and can, of course, bite hard if the hawk gives him a chance. Next to him in order of difficulty comes the common gull; and last in order is the black-headed gull, which will hardly be vanquished except by a cast of very first-rate hawks, and then on a calm day. All gulls have a great advantage when the wind is high, and usually escape, so that it is best not to fly them at such times, for fear of discouraging the hawk. Peregrines must be entered at bagged gulls, and fed after a kill on pigeon, or some very palatable food. It is also very advisable to use a make-hawk when available. On a very still day it is possible that a single hawk in good practice might take a common gull at the first stoop, if she had a good start; but if that failed, the quarry would most likely escape.
