It is not unusual to see the male bird, with its body erect and outspread wings, looking like the strange figures we employ as armorial bearings. When caged, the Moros still appear to prefer living upon the ground, over which they hop rather than walk, and here they usually pass the night. They will often conceal themselves, but never creep into holes that have a narrow entrance. When a party of them is engaged in preening and expanding their feathers in the sun, the spectacle they afford is very striking and beautiful. Unfortunately, in captivity their plumage soon loses its magnificent red colour, but, despite its loss, they always present a pleasing appearance. The Desert Trumpeter should be fed, like others of its species, upon seeds, in the choice of which it is far from dainty, though it prefers hemp or millet, and will also eat the green heads of the dandelion, the seeds of which it picks out most dexterously; neither does it refuse ears of corn nor the leaves of some plants, such as lettuce, cabbage, &c.; but it will not eat insects, with the exception of the pupæ of ants. In fact, it is by no means particular as respects diet, and is very easily reared. The Moro will frequently breed in captivity, and with a little care and patience may be completely tamed; it does not require any artificial warmth, for the scorching days and icy cold nights of the Sahara seem to render it indifferent to any change of temperature. Should the Moro be separated from its species it will seek the society of other birds, and we have known a case in which a Desert Trumpeter mated with a small pigeon (_Columba passerina_) of twice its own size. For the construction of the nest it prefers a cage that is hung up at some height, the bars of which are rather wide apart, and will only build with straw, which they collect by beakfuls at a time, but utterly reject hay or moss as unfit for the purpose. The interior is lined with feathers. The male bird carries some of the materials to the nest, but it is constructed almost entirely by the female. The pair we observed spent some time inside, one entering as the other left, and they appeared occasionally to have considerable difficulty in managing the conveyance of some of the long straws, with which they grappled. Our birds laid their first egg in April, and another was daily added till there were four. The mother, who but rarely left the nest, would probably have sat upon her brood, had we not determined to sacrifice half her stock on the altar of science. The remaining two eggs we placed in the care of a canary that was an excellent sitter, and brought her young charges out of the shell within a fortnight of their being placed under her. The nestlings were by no means so unsightly as those of singing birds usually are, and were covered with a thick, fine, white down, which formed a sort of crest upon the head; the bare places on the neck, &c., were of a flesh colour.
