The emu is Australia's largest bird and the second largest bird on Earth, after the ostrich. Emus can be found in most regions of mainland Australia, although they avoid densely populated areas, dense forests and arid zones.
An emu is capable of running at speeds up to 50 km/h. The bird's long legs allow it to take steps of up to 275 cm. The emu leads a nomadic life and can travel long distances in search of food. Just like the ostrich, the emu does not have teeth, so it swallows stones, glass shards and pieces of metal to grind food in its digestive system.
