Ague, or a low fever nearly resembling it, attacks hawks much in the same way as human beings. There are shivering fits and alternations of hot and cold, which may be discovered by feeling the body with the hand. The cause is often exposure to cold after becoming heated by flying or standing in the sun, or confinement in a draughty or cold place. The sufferer droops her wings, and looks miserable generally. She should be put in a sheltered place, rather warm than cold, and fed often, sparingly, on the best light food that is to be had. When the hot or cold fit is on she should be left as quiet as possible, but when it goes off she should be carried, and even flown a little, if she will; and she should by no means be left alone in any dismal place without company. When her attention is occupied she will have less inclination to mope or give way to the malady, and is much more likely to improve. If the affection is obstinate and the hot fits frequent, about two scruples of rhubarb may be given (for a falcon) in a casting of cotton wool, followed after two or three hours by a moderate meal of something freshly killed and light. If, however, the shivering fits predominate, or the hawk has become low in condition and has a poor appetite, the dose must be administered with caution and in moderation, and the patient should be coaxed and induced to take as much as she will, up to half a crop, of some heating food, such as freshly-killed sparrows, which are best of all, pigeons, or, in case of a goshawk, young rats; and if at a subsequent meal a sheep's heart is given (which such hawks can very easily pick at) it may be washed in wine in which has been boiled sage, mint, cinnamon, cloves, or some such aromatic herb. In all cases the invalid must be petted and made much of until she has regained her robust health and appetite.
