pheasant: [13] Etymologically, the pheasant is a bird from the ‘Phasis’. This was a river in the Caucusus, where the pheasant is supposed according to legend to have originated. The Greeks therefore called it phāsiānós, the ‘Phasian bird’, and the word passed into English via Latin phāsiānus and Anglo-Norman fesaunt. [pheasant etymology, pheasant origin, 英语词源]
