Birds in Wikipedia
Bird. - No other classification of birds than into clean and unclean is given. The Jews, before the Babylonian captivity, had no domestic fowls except pigeons . Although many birds are mentioned, there occur few allusions to their habits. Their instinct of migration, the snaring or netting them, and the caging of song birds are referred to.
Bird, Dyed. - So does the English version, Jer., xii, 9, wrongly interpret the Hebrew 'áyit. which means beast of prey, sometimes also bird of prey.
Bird, Singing. - This singing bird of Soph., ii, 14, according to the D.V., owes its origin to a mistranslation of the original, which most probably should be read: "And their voice shall sing at the window"; unless by a mistake of some scribe, the word qôl, voice, has been substituted for the name of some particular bird.
Birds, Speckled, Hebrew çãbhûá' (Jeremiah 12:9). A much discussed translation. The interpretation of the English versions, however meaningless it may seem to some, is supported by the Targum, the Syriac, and St. Jerome. In spite of these authorities many modern scholars prefer to use the word hyena, given by the Septuagint and confirmed by Ecclesiasticus, xiii, 22 as well as by the Arabic (dábúh) and rabbinical Hebrew (çebhôá'), names of the hyena.
