According to old Gesner, the gall of this species was regarded in his time as an infallible remedy for many most dissimilar complaints. THE MONK VULTURE. [Illustration: THE MONK VULTURE (_Neophron pileatus_).] [Illustration: AFRICAN VULTURES (_Gyps fulvus_).] The MONK VULTURE (_Neophron pileatus_) resembles the bird last mentioned in several respects, but differs from it in many particulars; the beak being comparatively short and the wings broader; the tail projects in a straight line; the forehead and the back of the head and nape are covered with a short woolly growth of feathers; the bare portions of the face and throat are also larger than in the Scavenger Vulture; the apertures of the ears are well developed, indeed almost muscular, and the fore part of the throat is covered with wart-like excrescences. The plumage is of an uniform chocolate brown, while the soft feathers at the back of the head are grey. The beak is greyish blue, darkest at its tip; the foot pale grey, the cere light violet, the bare head and throat are blueish red. The young are recognisable by the comparative paleness of their tints, and the dark brown colour of the back of the neck, the smooth skin upon the throat, and their less conspicuous ears. The length of this species is twenty-six, its breadth sixty-six inches; the wing measures seventeen inches, and the tail nine and a half. [Illustration: THE SCAVENGER, OR EGYPTIAN VULTURE (_Percnopterus stercorarius_ or _Neophron Percnopterus_).] The Monk Vulture is met with throughout almost the whole of the African continent, but is especially numerous upon the banks of the Blue and White Nile and on the shores of the Red Sea. So common is it in Abyssinia and Massowah, that large parties are often seen perching about the roofs and trees, as the crows do with us, or picking up their food around the houses with the utmost confidence and fearlessness. Before the natives have left their huts in the morning, these active servants are at the door, ready to begin their task of cleansing, as soon as the family will allow them to enter and remove whatever filth may have accumulated. So extremely feeble is the beak of these birds, that they seem to be almost entirely dependent upon man for the means of subsistence; and those who have never visited tropical countries can scarcely imagine how ably and perseveringly they perform the work that has been assigned to them. The movements of the Monk Vultures are active, and their habits very social; even during the breeding season the parties do not separate, but form settlements upon such groups of suitable trees as are at some distance from the towns and villages. The nests are usually placed upon the higher branches, and do not exceed one foot in diameter; they are flat in shape, and formed of twigs very nicely woven together; the interior is so small as to be capable of containing but one nestling. The solitary egg is
