The food of the Desert Trumpeter consists almost exclusively of different kinds of seeds, with probably a small quantity of leaves or buds. Water is an indispensable requisite. However troubled, scanty, or lukewarm the spring may be, these birds will visit it at least once in the day, so that their appearance is ever a welcome sight to thirsty travellers. They are always seen at the spring, both morning and evening, drinking much and in long draughts, and frequently bathing in shallow water. The breeding season commences in March, at which time the male has donned his gala dress, and, with his chosen mate, has separated himself from the flock; the little couples may very frequently be found perched sociably near the clefts of the rocks, whilst through the air rises the protracted trumpet-like call of the male, and the lark-like note of the female. We saw a pair of these birds upon the banks of the Nile, busily carrying away materials for their nest, but were unable to discover what they consisted of, as the rocks on both sides of the stream offered far too secure a brooding-place to allow us any chance of finding them; we learned, however, from the goat-herds that the Desert Trumpeter builds in the clefts and fissures of the blocks of lava, or under large overhanging stones. The nest, we were told, is artistically constructed of large blades of grass found in the desert, and lined with wool or feathers; in this the three eggs that constitute the brood are laid. It is probable that these birds breed twice in the year, and that they only again join the flocks amongst which their young ones are already numbered, when their parental duties are accomplished. During the autumn and winter they wander to a considerable distance, appearing even in the Canary Isles, and some instances have been known of their falling exhausted upon the deck of ships, that were passing in that neighbourhood. They are never molested by man, and were there no such creatures as Wild Cats and Ichneumons, Falcons or Kites (the latter being very destructive to them in their winter flight through the desert), these remarkable birds might live an undisturbed and happy life. The naturalist may, with care, capture them while drinking, and as many as heart can desire may be obtained from among the stones. It is, however, difficult to take them alive, as a decoy of the same species is indispensable for the purpose. The latter should be fastened in some desert place, or on the borders of a stubble-field, as far from trees or bushes as possible, in such localities as they are known to frequent. The decoy-bird instantly commences uttering its incessant call, and soon attracts large numbers of its wild companions, who alight and hop, as though dancing from one stone to another; they will linger for a moment at a distance, but come near enough to be recognised by their plumage and the brightness of their eyes; next they begin to peck up the food that is strewn about, and a
