aigrette
tuft of long, white heron (usually egret) plumes used as a decorative headdress, or any other ornament resembling such a headdress. Such plumes were highly prized as ornaments in Middle Eastern ceremonial dress. Jeweled aigrettes, at first made in the form of a tuft of plumes, became an adornment for turbans in Turkey, particularly during the Ottoman period (1281-1924).
