The European mouflon ("Ovis orientalis musimon") is the westernmost and smallest sub-species of mouflon. In Corsica and Sardinia the European mouflon was endangered by hunting and poaching. The largest wild animal and mammal currently residing in Cyprus is the endemic Cypriot mouflon. The mouflon is thought to be the ancestor for all modern domestic sheep breeds. For example, in northern Iran they produce hybrids with Asiatic mouflon under natural conditions. In 2015 there were an estimated 6,000 mouflon in Sardinia. European mouflon are herbivores and eat a wide range of food. The scientific classification of the mouflon is disputed. The clashing of horns is one of the most familiar sounds of the mouflon. The Cyprus mouflon population contains only about 3,000 animals.
