Some young maccaws are fed on hemp-seed, which must always be of the year before, as the new would be too warm and dangerous. Yet they must not be fed entirely on this food, but there must be added white bread soaked in milk or water, as has already been mentioned, some fruit and nuts, but never bitter almonds, as they will infallibly kill all young animals. In all cases the excrements of the bird will indicate the state of its health, and whether the food ought to be changed or not. Although maccaws rarely want to drink, as their food is very moist, yet they must not be left without water, which is generally placed in one of the divisions of their tin drawer. It is also a good thing to entice them to bathe, nothing is more favourable to their health, or better facilitates the painful operation of moulting, or keeps their feathers in better order. A little attention to these favourites, deprived of their liberty, their natural climate, and food, cannot be too much trouble to amiable persons who are fond of them, and to whom these pretty birds become greatly attached. BREEDING.--The red and blue maccaws build their nests in the holes of old decayed trees; they enlarge and make the hole even with their beak, and line it with feathers. The female, like that of the other American parrots, breeds twice in the year, laying two eggs each time, which are exactly like those of the partridge. In Europe the females also lay well, but the eggs are generally unfruitful; when they are not so it is very difficult to make the mother sit; there are, however, a few examples of the female maccaw being so well inclined to perform this office, that she will sit on pigeons' and hens' eggs, which are hatched in due time. The maccaws which we have in this country have generally been reared from the nest, particularly those which speak, for the old ones would be too savage and untractable, and would only stun one with their unbearable cries, the faithful interpreters of their different passions. DISEASES.--Amongst those to which maccaws are particularly subject, declines are the most frequent. Some cures for this are mentioned in the Introduction, which it would be well to employ. During the moulting season attention must be redoubled, not only to keep them in health but to preserve their beautiful plumage.
