The quetzal (locally: [keˈtsal]; code: GTQ) is the currency of Guatemala. It is named after the national bird of Guatemala, the Resplendent Quetzal. In ancient Mayan culture, the quetzal bird's tail feathers were used as currency. It is divided into 100 cents, called centavos in standard Spanish or lenes in Guatemalan slang. The plural is quetzales.
