On the other hand, if there is a really good prospect of a successful flight when the fugitive is routed out, it is, of course, very encouraging to the hawk to put him up. Every effort should be made to do this when the hawk is waiting on in a good position, so that, having killed, she may be pleased with the whole performance, including the men's share in it, and may perhaps imagine that the reason the quarry was got out so conveniently for her was because she waited on well. Hawks, whether waiting on in the air or at perch in a good place, soon get to know very well what the men are about when hunting up a bird that has put in. In the case of merlins, which naturally stand by on the ground while a lark is being searched for, it is almost always better to take them up on the fist as soon as it is determined to pick up or try to capture the quarry. Otherwise the lark, having his wits about him, may take advantage of a moment when the hawk is looking the wrong way, and slip off unseen by her. Moreover, even if she sees him go, she will not start from the ground with so good a chance as from the elevation, small though it is, of your fist. As for sparrow-hawks and goshawks, they may, when a quarry puts in, either be called to the hand or allowed to wait close by at the standpoint which they themselves chose. Many of them prefer the latter plan whenever there is a tree handy, as from it they get a better view and more impetus for their stoop. Lanners, when flown at partridges in an enclosed country, may also be encouraged to go to perch in this way.
