The common emu or simply emu (Dromaius novaehollandiae), also known as great emu, is the second-largest living bird by height. It is endemic to Australia where it is the largest native bird and the only extant member of the genus Dromaius. The emu's range covers most of mainland Australia. Emus are soft-feathered, brown, flightless birds with long necks and legs.
