This species is frequently met with in the southern countries of Europe, and occasionally appears in the more central provinces of that continent; it also frequents Egypt, Nubia, Algiers, and Morocco; but although it is sometimes seen around the Himalayas, it is replaced in the lowland districts of Hindostan by the Gyps Indicus and Gyps Bengalensis, two very similar birds.
THE SPARROW-HAWK GOOSE VULTURE.
The SPARROW-HAWK GOOSE VULTURE (Gyps Rüppellii), the handsomest member of this group, is three feet two inches long, and seven feet six inches broad; the wing measures two feet, and the tail nine inches and a half. In the adult bird all the large feathers, except the quills and those of the tail, are dark brown, tipped with a dirty white, crescent-shaped patch, thus giving a chequered appearance to the body. The skin of the neck is greyish blue, and shades downwards at its sides into a reddish hue, these colours being distinctly visible through the few scanty feathers with which it is overspread. The eye is silver grey, the beak yellow at the base and grey at the tip, the cere black, and the feet dark grey. The frill around the neck is formed of short, hairy, white feathers. In the young birds the small feathers are dark greyish brown, with yellowish brown shafts, and the quills and tail-feathers blackish brown. The eye is pale reddish brown, the cere and beak are black, the latter tipped with blue; the feet are greenish grey; the ruff is composed of long, narrow, dark brown feathers, each with a yellowish shaft. Several years elapse before the young acquire the full plumage of the adult birds.
The Sparrow-hawk Goose Vulture inhabits Nubia, and all the central portions of Africa with which we are acquainted. The southern portion of that continent possesses another species, the Gyps Kolbii, but of its distinguishing features we cannot speak with certainty. All the various species of Goose Vultures usually frequent mountain ranges, and build their nests on the rocks or upon trees. They live for the most part in very large flocks, which form extensive settlements during the breeding season, and constantly associate with a variety of other birds. In many respects they are inferior to the rest of the family, but their flight is light and elegant, and they walk with such rapidity that a man must run very fast indeed in order to compete with one of them on terra firma. In disposition all are violent and mischievous, and so extremely quarrelsome that battles and disputes are of constant occurrence between them and other Vultures; even those of the same species do not live on much better terms, and often engage in such deadly encounters that they appear entirely regardless of danger, and will allow a man to approach close to them. We have heard, on reliable authority, of an instance in which a shepherd was compelled to employ the "argument of a thick stick" to a couple of Goose Vultures, with which he laid about him very freely before he could persuade them to relinquish their hold upon each other, and retire from the field. According to our own observations, these birds do not begin their search for carrion until the day is far advanced. When they have found a carcase, they at once commence upon the entrails, plunging their heads into the interior, and dragging out their favourite parts with great excitement and violence; Lázár tells us that they often fall upon sick and dying sheep, and kill the poor beasts in this revolting manner.
In Europe the Goose Vulture breeds about March, and places its nest, which is formed of small branches, upon a rock. Many couples often build but a few paces from each other, and it is not unusual to see the nests of the Black Stork and some species of Eagles forming part of their settlements. The brood consists but of one coarse-shelled white egg, which in size resembles that of a Goose. Both parents assist in the somewhat lengthy process of incubation, and tend their little, round, woolly ball of a nestling with great devotion and patience, for so weak is it when it first sees the light, that three months often elapse before it is able to fly. It would be almost impossible to render one of these birds really tame, but we have heard of an instance in which a Goose Vulture became so much attached to an old mastiff belonging to its master, that when the dog died its feathered companion refused to devour the body, even when very hungry, and, after pining for a few days, expired, apparently through grief at its loss. The feathers of the Goose Vulture are much esteemed in Egypt, and large sums, we are told, were formerly paid by Turkish merchants for articles of dress made with them by some tribes of Arabs.
The CRESTED VULTURES are distinguished from the above group by their strength and compactness of body, as well as by their muscular neck, large head, powerful, eagle-like beak, and broad wings. Their plumage is also thicker and softer than in the Goose Vultures; the head is covered with short, curly, wool-like down, which is prolonged at the nape into a kind of crest, the neck and part of the throat are bare, but the lower part is ornamented with a frill, formed of large, broad, dark feathers.
THE COWLED VULTURE.
The COWLED, or BROWN VULTURE (Vultur cinereus), as the European member of this group is called, is forty-one inches and a half long, and eighty-five broad; the wing measures twenty-nine, and the tail fifteen inches. The female is from one inch and a half longer, and from two to three inches broader than her mate. The plumage of this bird is of an uniform dark brown; the beak is marked towards the centre with red or violet, and the bare places on the throat with grey. The plumage of the young is glossier and darker than that of the adults, and the downy feathers on the top of the head are dirty whitish brown.
The Brown Vulture lives and breeds throughout all the most southern countries of Europe, and is met with in Africa in the regions around the Atlas Mountains. In Asia it is becoming extremely numerous, owing, it is supposed, to the rapid spread of disease amongst the cattle, whose carcases afford it a constant supply of food. The movements of this species are distinguished by a dignity that is very unusual amongst the Vultures. Its eye is fiery and intelligent, its bearing much like that of the Eagle, and its entire demeanour calm and almost majestic. Even when feeding, it exhibits none of the haste and violence observable in the Goose Vultures. Its principal food appears to be carrion, but it rarely touches the entrails, usually contenting itself with eating the flesh and swallowing the bones of the prey, which, we are told on good authority, it sometimes kills. Unlike those species above described, the Brown Vulture builds exclusively upon trees; its nest is large, and formed of thick boughs and small branches, the flat interior being lined with thin dry twigs. The one white coarse-shelled egg that constitutes the brood in size resembles that of the Goose. Both parents tend their offspring with great care, and feed it upon flesh for four months, as until that time it is unable to fly. Attempts to render this bird tractable in captivity usually prove fruitless, but instances have been lately known in which the Brown Vulture has been made so tame as to run about a farm-yard on excellent terms with its inhabitants, and to allow children to play with it.
