Toucans. These birds are all distinguished by their enormous bills, which are convex above, and much hooked towards the point; although very light, they are of great strength, and, being toothed at the edges, they are formidable instruments of destruction, when used, as they sometimes are. in attacking other birds, which the Toucans chase from their nests, in order to get at the eggs and young, which they devour in sight of the unhappy parents. During the season of incubation they are said to live chiefly on this kind of food, although at other times they eat fruits, insects, and the tender buds of plants. The Toucans are found chiefly in the warmer regions of America, where they go in little flocks of from six to ten; although heavy fivers, they reach the top of the highest trees, where they are fond of perching. They make their nests in the hollows of trees. The female lays but two eggs, like other Parrots. The young are easily reared and tamed; they will eat almost anything; their mode of eating solid food is very peculiar. When the morsel is presented, they take it on the point of the bill, throw it upward, and then catch it in the open mouth So dexterously that it goes at once into the aperture of the gullet, and is then swallowed without difficulty. The Toucans are so sensible to cold that they dread the night air, even in tropical countries; it is therefore necessary to keep them in a warm temperature. Their tongues are more hard and inflexible than those of other Parrots; consequently they do not shine as speakers - their utterance is usually confined to a kind of croak.
