A large flightless bird native to Australia, standing about 1.6 to 1.9 metres tall and second only to the ostrich among living birds.
In 1932, Australia waged war on emus — and lost. To stop ~20,000 emus wrecking crops, soldiers brought two machine guns and 10,000 rounds, but the birds split into small groups and outran the fire; one gun jammed. After two months, under 1,000 were killed — the war birds won.
