The emu is a large, flightless bird native to Australia and the only living species in the genus Dromaius. It is the tallest native bird in Australia and the second-largest living bird by height after the ostrich.

What it is

The emu (Dromaius novaehollandiae) is a large, brown, long-necked, long-legged ratite bird. It is closely related to other ratites like the cassowary, shares their inability to fly, and is found across mainland Australia.

Key details

Emus stand more than 1.5 m tall, up to about 1.9 m, and can sprint at speeds of up to 48 km/h. They are omnivores, eating seeds, fruits, flowers, young shoots, grasses, insects, and occasionally small vertebrates.

Habitat and range

These birds live across much of mainland Australia in eucalyptus forest, woodland, heath land, desert shrubland, and sand plains. They forage during the day and can travel long distances for food.

  • Emus are the tallest native bird in Australia and the second-largest living bird by height.
  • They are flightless ratites that can run up to 48 km/h.
  • Emus eat both plants and animals.
