Is the emu a flightless bird?

Emus are not extinct, nor even endangered. They are the second largest birds in the world, after the ostrich, and exist in abundant numbers on the Australian mainland.

The Emu is extinct on the island of Tasmania but is common in all other states and mainland territories of Australia. There also used to be two dwarf emu species, existing on Kangaroo island (off South Australia) and King island (Bass Strait). The dwarf emus and the Tasmanian emus were driven to extinction by the arrival of European settlers.
