Heb. peres = to "break" or "crush", the lammer-geier, or bearded vulture, the largest of the whole vulture tribe. It was an unclean bird ( Leviticus 11:13 ; Deuteronomy 14:12 ). It is not a gregarious bird, and is found but rarely in Palestine. "When the other vultures have picked the flesh off any animal, he comes in at the end of the feast, and swallows the bones, or breaks them, and swallows the pieces if he cannot otherwise extract the marrow. The bones he cracks [hence the appropriateness of the name ossifrage, i.e., "bone-breaker"] by letting them fall on a rock from a great height. He does not, however, confine himself to these delicacies, but whenever he has an opportunity will devour lambs, kids, or hares. These he generally obtains by pushing them over cliffs, when he has watched his opportunity; and he has been known to attack men while climbing rocks, and dash them against the bottom. But tortoises and serpents are his ordinary food...No doubt it was a lammer-geier that mistook the bald head of the poet AEschylus for a stone, and dropped on it the tortoise which killed him" (Tristram's Nat. Hist.).
(the bone-breaker ). The Hebrew word occurs, as the name of an unclean bird, in ( Leviticus 11:13 ) and Deuteronomy 14:12 It is probably the lammergeyer , or bearded vulture as it is sometimes called, one of the largest of the birds of prey. It well deserves its name ossifrage, bone breaker , for "not only does he push kids and lambs and even men off the rocks, but he takes the bones of animals that other birds of prey have denuded of the flesh high up into the air and lets them fall upon a stone in order to crack them and render them more digestible even for his enormous powers of deglutition. Marrow-bones are the dainties he loves. This is probably the bird that dropped a tortoise on the bald head of poor old AEschylus." --N. H. Simpson.
os'-i-fraj (perec; gups; Let Ossifraga):
The great bearded vulture known as the lammer-geier (Leviticus 11:13; Deuteronomy 14:12 the King James Version, the Revised Version (British and American) "gier-eagle"). The Hebrew name perec means "to break." Let oasis, "bone," and frangere, "to break," indicate the most noticeable habit of the bird. It is the largest of the vulture family, being 3 1/2 ft. in length and 10 in sweep. It has a white head, black beard on the chin, and the part of the eye commonly called the "white" in most animals, which is visible in but few birds, in this family is pronounced and of a deep angry red, thus giving the bird a formidable appearance. The back is grayish black, the feathers finely penciled, the shaft being white, the median line tawny. The under parts are tawny white and the feet and talons powerful. It differs from the vulture in that it is not a consistent carrion feeder, but prefers to take prey of the size captured by some of the largest eagles. It took its name from the fact that after smaller vultures and eagles had stripped a carcass to the last shred of muscle, the lammergeier then carried the skeleton aloft and dropped it repeatedly until the marrow from the broken bones could be eaten. It is also very fond of tortoise, the meat of which it secures in the same manner. As this bird frequents Southern Europe, it is thought to be the one that mistook the bald head of Aeschylus, the poet, for a stone and let fall on it the tortoise that caused his death. This bird also attacks living prey of the size of lambs, kids and hares. It is not numerous and does not flock, but pairs live in deep gorges and rocky crevices. It builds an enormous nest, deposits one pinkish or yellowish egg, and the young is black. It requires two years to develop the red eyes, finely penciled plumage and white head of the adult bird. It was included among the abominations because of its diet of carrion.
