They generally build their nests in the loftiest trees, and occasionally in thickets of brushwood among the rocks. When frost comes they visit farm yards and steal poultry, and when pressed by hunger they become very bold.
[Illustration: Vulture and Griffin Fighting over Prey.]
The Vultures are the most disgusting of the feathered creation. Like the Hyena among animals, they rarely attack living prey, but live almost entirely upon putrid flesh, and after filling themselves with this food they will remain in a state of stupid torpor until it is digested. Yet much as we despise them, we must recognize their friendly mission to mankind, for while the other Birds of Prey are often of use to the farmers, etc., in killing off the field and barn Mice, and destructive insects, the Vultures remove all decaying flesh and putrid matter from the earth that might otherwise breed disease.
The Vultures fly heavily, but mount aloft to great altitudes. They have wonderful powers of vision. Should a carcass be left on the plain they immediately see it, and drop down, turning over and over in their hurry to arrive at the feast.
The Bearded Griffon, Condor, King Vulture, Urubu, Turkey Buzzard, Fulvous Vulture and Pondicherry Vulture, are the principal species of the great Vulture family.
The Bearded Griffon is the celebrated Lammergeyer, described by some Naturalist under the name of the Golden Vulture. The Lammergeyer forms, as the name indicates, an intermediate genus between the Eagles and the Vultures, having head and eyes like the Vultures and feet and strong beak like the Eagles. It owes its name—Bearded Griffon—to a tuft of stiff hair that is under the beak. The loftiest mountains of Europe, Asia and Africa are its home, and its aerie, which is of great size, is built among the most inaccessible rocks.
In our illustration, one of these Bearded Griffons or Golden Vultures has discovered a Common Vulture (sometimes called the Goose Hawk) feasting upon the carcass of a Pamir-sheep (one of the greatest of the Sheep species, inhabiting lofty plateaus above the tree limit).
The Vulture at the feast hears the rushing of mighty wings and the Bearded Griffon, followed by his wife, drops on a neighboring rock.
