The Emu is Australia's tallest native bird, reaching 1.6-1.9m when standing erect. It weighs 30-45kg, which is lighter than its closest living relative, the Southern Cassowary Casuarius casuarius. Emus are easy to identify. Adult Emus are covered with shaggy grey-brown feathers except for the neck and head, which are largely naked and bluish-black. The wings are greatly reduced, but the legs are long and powerful. Each foot has three forward-facing toes and no hind toe.
