Two species of swan have been found in Palestine, the whooper, or wild swan (Cygnus musicus, or ferus), and the Cygnus olor, or mansuetus; they are, however, comparatively rare.
Some take the "barburim abusim" of the Talmud (B. M. 86b) to mean "swans," though the usual rendering is "fattened hens."
