Mouflon sheep (Ovis orientalis)
Among male mouflons, horn size really counts. This wild sheep’s horns grow continuously and are never shed, so older rams have massive, spiral headgear to blunt competition from younger males. During the fall rutting season, even ewes prefer the bigger-horned males.
When winter turns cold and snowy, mouflons descend from high pastures to the steppe to join other ungulates searching for food. Coarse outer fur and a woolly inner coat allow them to withstand extreme cold. But competition for grazing land from domestic herds has made the Asiatic mouflon increasingly rare in much of its range.
