to warmer regions, whilst those inhabiting Asia and Africa are stationary throughout the year. It would be impossible to over-estimate the immense services rendered to man by the Scavenger Vultures, to whose appetite no kind of filth or refuse comes amiss. They devour carrion freely, but this forms by no means their principal subsistence; offal of all kinds they consume with avidity, and were it not that Providence had assigned to these most active birds the task of clearing away the garbage that the inhabitants of tropical and of some European cities are too indolent to remove, fever and pestilence would rage with unremitting fury. Many writers speak of these invaluable benefactors to humanity in terms of strong disgust, but for our own part we consider this by no means warrantable. Ugly they certainly are, and the odours they spread around them somewhat of the strongest; but there is such a thing as the _beauty of fitness_, and, to our minds, this is possessed by the Scavenger Vultures in an eminent degree, so exactly are they adapted to the part they have to play in the economy of Nature. So totally are these birds destitute of fear, that they not only approach, but enter the houses requiring their ministrations, and we have frequently seen them busied in clearing away the refuse strewn about the tents of the Arabs, or accompanying caravans for a whole day in the hope of obtaining the scraps thrown away by the travellers. Unlike many of its congeners, the Neophron does not usually smear itself over with filth whilst eating; it even appears to exercise a certain care in this particular, as it steps quietly about, feeding after the manner of a Barn-door Fowl. When satiated it retires to a quiet tree or rock, and there remains in a kind of indolent doze, while the work of digestion is going on, a process which often occupies several hours. When about to fly it springs from the ground with considerable force, and, after a few sharp strokes of its wings, floats slowly and gracefully through the air, without any further movement of its wings. This species is very sociable, and flies about either in pairs or small parties, which usually form a settlement during the breeding season, building their nests as near to each other as possible, upon rocks, pagodas, tombs, or similar situations. The nest is made of twigs and a variety of materials, of which rags often form a part. The brood generally consists of two long eggs of a yellowish white colour, spotted with yellowish or reddish brown; we have seen them also marbled all over with deep crimson lines. The young are covered with greyish down when first hatched, and are fed with food regurgitated from the crop of the parent birds; many months elapse before they are fully capable of providing for their own wants. If trained while young, the Scavenger Vulture is as tractable as a Barn-door Fowl, and will learn to follow its master about with the affection of a dog.
