Winged monkeys Winged monkeys (often referred to in adaptations and popular culture as flying monkeys) are fictional characters created by American author L. Frank Baum in his classic children's novel "The Wonderful Wizard of Oz" (1900). The winged monkeys are exactly what the name implies: jungle monkeys with powerful bird-like feathered wings attached to their shoulders which allow them to fly. They are most notable from the famous 1939 musical movie by MGM. Ever since, they have taken their own place in popular culture, regularly referenced in comedic or ironic situations as a source of evil or fear.
