The Prince of Wales's feathers is the heraldic badge of the Prince of Wales, during the use of the title by the English and later British monarchy. It consists of three white ostrich feathers emerging from a gold coronet. A ribbon below the coronet bears the motto (, "I serve"). As well as being used in royal heraldry, the badge is sometimes used to symbolise Wales, particularly in Welsh rugby union and Welsh regiments of the British Army. Bearers of the motif The badge has no connection with the native Princes of Wales. House of Plantagenet The ostrich feathers heraldic motif is generally traced back to Edward, the Black Prince (1330–1376), eldest son and heir apparent of King Edward III of England. The Black Prince bore (as an alternative to his differenced royal arms) a shield of Sable, three ostrich feathers argent, described as his "shield for peace", probably meaning the shield he used for jousting. These arms appear several times on his chest tomb in Canterbury Cathedral, alternating with his paternal royal arms (the royal arms of King Edward III differenced by a label of three points argent). The Black Prince also used heraldic badges of one or more ostrich feathers in various other contexts. The feathers had first appeared at the time of the marriage of King Edward III to Philippa of Hainault, and Edward III himself occasionally used ostrich feather badges. It is therefore likely that the Black Prince inherited the badge from his mother, descended from the Counts of Hainault, whose eldest son bore the title "Count of Ostrevent", the ostrich (, Old French spellings including ostruce) feathers being possibly an heraldic pun on that name. Alternatively, the badge may have derived from the Counts of Luxembourg, from whom Philippa was also descended, who had used the badge of an ostrich. Sir Roger de Clarendon, an illegitimate son of the Black Prince by his mistress Edith Willesford, bore arms of Or, on a bend sable three ostrich feathers argent; King Richard II, the Black Prince's legitimate son, used ostrich feather badges in several colours and awarded augmented arms with ostrich feather supporters to Thomas de Mowbray, 1st Duke of Norfolk (1366-1399), the second son of John de Mowbray, 4th Baron Mowbray, and Elizabeth de Segrave, suo jure Lady Segrave, daughter and heiress of John de Segrave, 4th Baron Segrave, by Margaret, Duchess of Norfolk, daughter and
