The ABBAGAMBA, or ABYSSINIAN HORNBILL (_Bucorax Abyssinicus_), a well-known African species of the above family, is a large, powerfully-formed bird, with short wings and tail and long legs. Its huge beak, about a foot in length, is slightly curved, flat at its sides, and blunt at the tip. The base of the upper mandible is surmounted by a high protuberance. The regions of the eye and throat are bare, and very brightly coloured. In the wing the sixth quill is longer than the rest. The entire plumage, except six yellowish white primary quills, is of a glossy black, the eye is dark brown, and the beak black, with a red and yellow spot on its upper mandible. The eye-rings and throat are dark grey, the latter bordered with bright red. The female is smaller than her mate, and has only a comparatively small portion of her neck bare. The length of the male is forty-three inches and a half, and his breadth seventy inches; the wing measures twenty-one inches and three-quarters, and the tail thirteen inches and a half.

This remarkable bird is found over a large portion of Africa, and is common in Abyssinia, where it subsists principally on a large beetle that abounds in the Teff fields at certain seasons. In some parts of the continent it is regarded with superstitious veneration, and is known as the Tier el Naciba, or Bird of Destiny. So strong, indeed, is this feeling among the natives, that they will not permit an Abbagamba to be killed near their dwellings, lest they should lose their flocks and cattle by disease; under any circumstances, however, this species is but little liable to molestation, as the disgusting stench emitted by its body renders a near approach to it almost impossible. During the breeding season the Abyssinian Hornbills live in pairs, but after that period wander about the fields in parties in search of locusts, grasshoppers, and beetles. Gourney tells us that they also devour snails, lizards, frogs, rats, mice, and similar fare. Insects they obtain by hacking in the ground with their powerful bill, and then, after tossing their victim in the air, catch it in their extended mandibles as it descends. According to Gourney they attack snakes with great intrepidity, employing their wing as a shield against the dangerous foe, and, should he prove formidable, calling in the assistance of their companions, in order more speedily to dispatch him. When excited, these strange birds present a most extraordinary appearance, as they stalk along with throat inflated and wings trailing, the tail meanwhile being constantly opened and closed, after the manner of a Turkey-cock. Their step, which resembles that of a Raven, is unsteady, and their movements in the air, contrary to the usually received idea, both light and graceful; they, however, rarely fly to any distance, but, if alarmed, merely rise and take refuge in a neighbouring tree. Should any suspicious sound attract the attention of a party of these birds, they stand erect and listen attentively, with bill wide open, and, at the first note uttered by one of their number, at once hurry to a place of safety, usually selecting such spots as command a free view of the surrounding country. The cry of the Abbagamba is deep, harsh, and so resonant that, according to Gourney, it can be heard at the distance of more than a mile. While engaged in attracting the attention of his mate, the male often continues his call, almost without intermission, for a quarter of an hour at a time, and is answered by her repeatedly in a somewhat higher tone. The nest, as we ourselves ascertained, is made in large hollow trees, with the entrance on the east side. The eggs, we learn from Heuglin, are small and round, with a rough white shell. A nestling found by us at first exhibited no trace of the horny excrescence on its bill, and, on being shut up in a yard with a variety of other live stock, soon became tame, and lived on excellent terms with its companions.
