The Australian Ratite is a large flightless bird native to Australia and is represented by the EMU, which is a three-letter word in the crossword. The EMU is the second-largest living bird by height, after the ostrich, and is the only extant member of the genus Dromaius. It is a fast-running, powerful bird and can travel great distances at a rapid pace. The EMU is an important cultural icon of Australia, appearing on the coat of arms and various coins.
