heron: [OE] Heron may well have originated in imitation of the bird’s cry, for its source was probably Indo-European *qriq- (whence also Russian krichat’ ‘call out, shout’). From this was descended prehistoric Germanic *khaigaron (source of Swedish häger ‘heron’), which was borrowed into Old French as hairon. English took it over as heron or hern (the latter now a memory surviving in personal names and placenames, such as Earnshaw). [heron etymology, heron origin, 英语词源]
