Sir Feathaz and Lady Feathaz are loud and gregarious Common Starlings. On their track Mur-Mur-Mur-Muration, they demonstrate that they are very sociable birds who excel at mesmerizing aerial displays. Their iridescent feathers appear black from a distance, but closer inspection reveals purple and green. Starling beaks are yellow, but the blue and pink edging along their beaks distinguish males from females.
