Following the arrangement which has been employed in this work, I shall begin with the bird which has been placed by zoologists at the head of its class, namely, the LÄMMERGEIER, the bird which may be safely identified with the Ossifrage of Scripture. The Hebrew word is "Peres," a term which only occurs twice when signifying a species of bird; namely, in Lev. xi. 13, and the parallel passage in Deut. xiv. 12. The first of these passages runs as follows: "These ye shall have in abomination among the fowls; they shall not be eaten, they are an abomination: the eagle, and the ossifrage, and the ospray." The corresponding passage in Deuteronomy has precisely the same signification, though rather differently worded: "These are they of which ye shall not eat: the eagle, and the ossifrage, and the ospray." The word _peres_ signifies a breaker; and the Latin term Ossifraga, or Bone-breaker, is a very good translation of the word. How it applies to the Lämmergeier we shall presently see. The Lämmergeier belongs to the vultures, but has much more the appearance of an eagle than a vulture, the neck being clothed with feathers, instead of being naked or only covered with down. It may at once be known by the tuft of long, hair-like feathers which depends from the beak, and which has gained for the bird the title of Bearded Vulture. The colour of the plumage is a mixture of different browns and greys, tawny below and beautifully pencilled above, a line of pure white running along the middle of each feather. When young it is nearly black, and indeed has been treated as a separate species under the name of Black Vulture. It is one of the largest of the flying birds, its length often exceeding four feet, and the expanse of its wings being rather more than ten feet. In consequence of this great spread of wing, it looks when flying like a much larger bird than it really is, and its size has often been variously misstated. Its flight, as may be imagined from the possession of such wings, is equally grand and graceful, and it sweeps through the air with great force, apparently unaccompanied by effort. The Lämmergeier extends through a very large range of country, and is found throughout many parts of Europe and Asia. It is spread over the Holy Land, never congregating in numbers, like ordinary vultures, but living in pairs, and scarcely any ravine being uninhabited by at least one pair of Lämmergeiers.
