Swan: (Heb. tinshemeth), thus rendered by the Authorized Version in (Leviticus 11:18; 14:16) where it occurs in the list of unclean birds Rut either of the renderings "porphyrio" (purple water-hen) and "ibis" is more probable. Neither of these birds occurs elsewhere in the catalogue; both would be familiar to residents in Egypt, and the original seems to point to some water-fowl. The purple water-hen is allied to our corn-crake and water-hen, and is the largest and most beautiful of the family Rallidae . It frequents marshes and the sedge by the banks of rivers in all the countries bordering on the Mediterranean and is abundant in lower Egypt.
