In groups guided by a matriarch and composed of his lineage, all ages are represented. The herd is mainly composed of females, young and young immature males. The size of the herd can fluctuate depending on the season, and the presence of food and water. Males live on their own or in groups of a few individuals. Their role is to move from one group of females to another. They are never far from the herds and enjoy their time together.
