Dr. Livingstone relates a very curious instance of "Bird Confinement" under very strange circumstances. In passing through Mopane country, in South Africa, his men caught a great number of the birds called _Korwé_ in their breeding-places, which were holes in the mopane trees. They passed the nest of a Korwé just ready for the female to enter; the orifice was plastered on both sides, but a space was left of a heart shape, and exactly the size of the bird's body. The hole in the tree was in every case found to be prolonged some distance upwards above the opening, and thither the Korwé always fled to escape being caught. In another nest that was found, one white egg, much like that of a pigeon, was laid, and the bird dropped another when captured: she had four besides in the ovarium. Dr. Livingstone first saw this bird at Kolenbeng in the forest: he saw a slit only, about half an inch wide and three or four inches long, in a slight hollow of a tree; a native broke the clay which surrounded the slit, put his arm into the hole, and brought out a red-beaked Hornbill, which he killed. He told Dr. Livingstone that when the female enters her nest she submits to a real confinement. The male plasters up the entrance, leaving only a narrow slit by which to feed his mate, and which exactly suits the form of his beak. The female makes a 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 quite fat, and is esteemed a very dainty morsel by the natives; while the poor slave of a husband gets so lean that, on the sudden lowering of the temperature, which sometimes happens after a fall of rain, he is benumbed, falls down, and dies. Dr. Livingstone, on passing the same tree at Kolenbeng about eight days afterwards, found the hole plastered up again, as if, in the short time that had elapsed, the disconsolate bird-husband had procured another wife. Dr. L. saw a nest with the plastering not quite finished, and others completed; he also received elsewhere, besides Kolobeng, the same account that the bird comes forth when the young are fully-fledged, at the period when the corn is ripe; indeed, her appearance abroad with her young is one of the signs they have for knowing when it ought to be so: the time is between two and three months. She is said sometimes to hatch two eggs, and, when the young of these are full-fledged, the other two are just out of the egg-shells: she then leaves the nest with the two elder, the orifice is again plastered up, and both male and female attend to the wants of the young.
