The red and blue maccaw is one of the largest of the parrot tribe, being two feet eight inches in length. The hardest stones of the peach cannot resist the strength of its beak, the upper mandible of which is very much hooked. The claws are directed forward, and two backward. The naked cheeks are covered with a wrinkled whitish skin. The head, neck, breast, belly, thighs, top of the back, and the upper wing-coverts are of the finest vermilion. The lower part of the back and the rump are light blue. The scapulars and large wing-coverts are a mixture of blue, yellow, and green. The colours sometimes vary, especially in the wings and tail, but the species will not be the less easily known on that account. The female very much resembles the male. HABITATION.--When wild it inhabits South America, and may be found in Brazil and Guiana, in damp woods, and always in pairs. In the house it may be let range at will, giving it a roost with several rings placed across. Like its fellows, it may be kept in a very large strong wire cage, high and wide enough to let it move with ease, and preserve its handsome tail in all its beauty. FOOD.--In its native country the fruit of the palm tree is its principal food; our fruit it also likes, but white bread soaked in milk agrees with it better; biscuit does not hurt it; but meat, sweetmeats, and other niceties are very injurious; and though at first it does not appear to be injured, it becomes unhealthy, its feathers stand up separate, it pecks and tears them, above all those on the first joint of the pinion, and it even makes holes in different parts of its body. It drinks little--this is perhaps occasioned by its eating nothing dry. Many bird-fanciers say that the best food for parrots is simply the crumbs of white bread, well baked, without salt, soaked in water, and then slightly squeezed in the hand. But though this appears to agree with them pretty well, it is however certain that now and then something else ought to be added. I have observed, indeed, that parrots which are thus fed are very thin, have hardly strength to bear moulting, and sometimes even do not moult at all; in that case they become asthmatic, and die of consumption. It is clear that feeding them only on this food, which has very little if any moisture in it, is not sufficient to nourish them properly, at least during the moulting season, and while the feathers are growing again. I never saw a parrot in better health than one which belonged to a lady, who fed it on white bread soaked in boiled milk, having more milk than the bread would absorb, which the parrot drank with apparent pleasure; there was also put into the drawer of its cage some sea biscuit, or white bread soaked in boiling water; it was also given fruit when in season. It is necessary to be very careful that the milk is not sour.
