Elite Nahua military insignia in the form of a whole quetzal bird covered with feathers and supported by a frame worn on the back. An item sent to Tenochtitlan from the tributary province of Tochtepec, they were worn by tlahtohqueh (rulers) and pipiltin (nobles) in postclassic central Mexico. They were also used to identify Tlaxcalan military units of Ocotelolco.
