Second-largest bird in the world after the Ostrich, the Emu stands two meters tall and measures two meters from head to tail. It is flightless, but capable of running at speeds up to 48 kilometers per hour.

Once found throughout Australia, except for the northeastern rainforests, the Emu has remained quite common and abundant in some areas, probably because it inhabits desert and dry scrub country far from the centers of human population. It has, however, been exterminated from Tasmania and Kangaroo Island, and has vanished from most agricultural regions, where great numbers have been killed.

Emus generally stay in one place while conditions are favorable, but become nomadic and wander considerable distances to avoid food or water shortages, as at times of drought. Breeding begins in autumn, when six to eleven very large dark Grey-green eggs are laid.
