Eagle in Wikipedia
Eagle. - So is generally rendered the Hebrew, néshér, but there is a doubt as to whether the eagle or some kind of vulture is intended. It seems even probable that the Hebrews did not distinguish very carefully these different large birds of prey, and that all are spoken of as though they were of one kind. Anyway, four species of eagles are known to live in Israel: aquila chrystos, aquila nvia, aquila heliaca, and circtos gallicus. Many allusions are made to the eagle in the Bible: its inhabiting the dizziest cliffs for nesting, its keen sight, its habit of congregating to feed on the slain, its swiftness, its longevity, its remarkable care in training its young, are often referred to (see in particular Job 39:27-30). When the relations of Israel with their neighbours became more frequent, the eagle became, under the pen of the Jewish prophets and poets, an emblem first of the Assyrian, then of the Babylonian, and finally of the Persian kings.
