These sheep live in mountains. In the summer, they come to grassy places to eat twigs, sage, buds, leaves and grass. These places are 1200 to 1500 meters above sea level. In the winter, they stay on the south sides of the mountains, where it is warmer. These places are about 1500 to 2200 meters above sea level. Although they do well in the cold, thinhorn sheep do not move easily through deep snow. They have short legs and small feet, so they cannot walk through snow or on top of it. Instead, they try to live in forests where the snow is not deep or near cliffs. They can climb the cliffs to get away from animals that want to eat them. They follow the same routes from summer places to winter places for generations.
