鸸鹋(学名：Dromaius novaehollandiae)，基本用 Emu [iːmjuː]),表示
is the largest bird native to Australia and the only extant member of the genus Dromaius. It is also the second-largest bird in the world by height, after its ratite relative, the ostrich. The soft-feathered, brown, flightless birds reach up to 2 m (6 ft 7 in) in height. The Emu is common over most of mainland Australia, although it avoids heavily populated areas, dense forest and arid areas. Emus can travel great distances at a fast, economical trot and, if necessary, can sprint at 50 km/h (31 mph) for some distance at a time.[1] They are opportunistically nomadic and may travel long distances to find food; they feed on a variety of plants and insects.
