These birds inhabit the Eastern Hemisphere, and are especially numerous in some parts of Asia and Africa. Dense woods and forests are their favourite resorts, and where these are to be met with they often live at an altitude of ten thousand feet above the level of the sea; only a few of the smaller species occasionally frequent shrubs or bushes. Lesson tells us that certain species devour nutmegs, from which their flesh acquires a most appetising flavour. Some writers inform us that they will consume carrion, and when in confinement have been known to swallow rats and mice whole, after bruising their bodies with their powerful mandibles. The Hornbills associate in flocks, which frequent woods and forests, and perch on the loftiest trees. We learn from the naturalist above quoted that the noise produced by a party of these birds when passing through the air is very alarming to those who are unaware that the strange sound that accompanies their movements is produced by the clattering of their huge mandibles, and the utterance of a loud croak; these discordant sounds bearing no distant resemblance to one of those sudden and violent winds which often come on unexpectedly in tropical climates. Their voice may be described as the blast of a bugle, combined with the sudden hiss of an exploding sky-rocket; they seem to utter these calls periodically, without any obvious reason, as if to relieve the monotony of their still and melancholy lives. Major Denham tells us that an Abyssinian species lives upon insects, fish, and snakes, and appears to display an especial instinct in finding the latter. The Hornbill discovers their vicinity while they are yet underground, digs on the spot, destroys the nest, and feeds on the venomous inhabitant and its eggs. "The first time I saw a Hornbill's nest," says Dr. Livingstone, speaking of another species, "was at Kolsberg, when I had gone to a forest for some timber. Standing by a tree, a native looked behind me, and exclaimed, 'There is the nest of a Korwé!' I now saw a slit only about half an inch wide, and three or four inches long, in a slight hollow of the tree. Thinking the word Korwé denoted some small animal, I waited with interest to see what he would extract. He broke the clay which surrounded the slit, put in his arm, and pulled out a Tockas, or Red-breasted Hornbill, which he killed. He informed me that when the female enters her nest, she submits to real confinement; the male plasters up the entrance, leaving only a narrow slit, that exactly suits the form of his beak, by which to feed his mate. The female makes the nest of her own feathers, lays her eggs, hatches them, and remains with the young till they are fully fledged. During all this time, which is stated to be two or three months, the male continues to feed her and the young family. The prisoner generally becomes fat, and is esteemed a very dainty morsel by the natives, while the poor slave of a
