The Emu War of Australia was a conflict between humans and birds. Emus are the second-largest living birds, standing at an average height of no less than 5.7 feet. They have long legs and necks with short wings (less than 8 inches). When emu populations grew and began wreaking havoc on crops, The Emu War of 1932 began.
Soldiers used World War I era machine guns against the emus. It took about 10 bullets to kill a single emu, leading officials to conclude that it wasn’t worth it. One soldier famously remarked, “The emus have proved that they are not so stupid as they are usually considered to be.”
