Falcon. In some translations of the Bible the falcon appears in the lists of unclean birds (Lev. 11:14; Deut. 14:13), (NKJV). As a bird of prey, it is often grouped with hawks. But a falcon is not a true hawk. The sport of hunting with trained falcons originated in ancient Persia. Great numbers of falcons are still seen in Palestine, as they surely were in Bible times (Job 28:7).
