Australia once declared war against emus and lost
Australia in 1932 declared a war against emus, as about 20,000 emus began occupying farmland, which was intended for WWI veterans. The Ministry of Defence deployed soldiers and provided machine guns to annihilate the birds. Only about 1,000 emus were killed and when the 'Great Emu War' was discussed in the Parliament, a representative stated that emus won the war.
