swon (tinshemeth, "chameleon," "tree-toad," "water-hen," "owl"; kuknos; Latin cygnus; Anglo-Saxon:
swan and swon): Mentioned only in old versions and the Revised Version margin in Leviticus 11:18: "the swan, and the pelican, and the gier eagle," and in Deuteronomy 14:16 Septuagint porphurion = "water-hen"; Vulgate (Jerome's Latin Bible, 390-405 A.D.) ibis). In the Revised Version (British and American) this is rightly changed to "the horned owl, and the pelican, and the vulture." A bird of the duck family wrongly placed among the abominations in old versions of the Bible, now changed to horned owl.
White and gray swans spend their winter migratory season on the waters of the Holy Land. They are among the most ancient birds of history; always have been used for food; when young and tender, of fine flesh and delicious flavor; so there is no possibility that they were ever rightfully placed among the birds unsuitable for food. Their feeding habits are aquatic, their food in no way objectionable.
