It is, however, very easy to mistake the symptoms, and to imagine that a hawk wants reducing when in fact she wants feeding up. The result, of course, of such faulty diagnosis will be that the treatment applied as a remedy aggravates the mischief already done. It is much easier to reduce a hawk than to get flesh on her again. The beginner should therefore be very sure that his hawk has been overfed before he shortens her daily supply of food. By making a mistake on the other side, and feeding up a hawk which is already a bit above herself, the worst inconvenience that is likely to follow, in the case of an eyess, is a little delay in getting her down to the lure. Passage hawks, especially for a while after they have first been reclaimed, are of course liable to be lost if too highly fed, for when disinclined to come to the lure or fist they are apt to rake away after chance quarry. But they may be full-fleshed and strong, and yet be eager for their food. It is a great mistake, though a very common one, to suppose that a thin hawk is necessarily a hungry one. Whether a hawk is fat or thin is a question of days, whereas it is a question of hours whether she is hungry or not. For instance, a peregrine may have had nearly a full crop every day for a week, and yet if on the eighth day she has only a very light feed in the morning she will be as hungry as a hunter on the ninth day in the afternoon. The tendency nowadays is rather to overfeed hawks, and to forget the old maxim about a fat hawk making "a lean horse and an empty purse." The amateur has been so loudly warned against keeping a thin hawk that in avoiding this reproach he falls into the other extreme, and attempts to fly his hawk when she is really not sharp-set at all.
