They are generally found in small herds comprising eight to twelve animals. Bull usually leads a solitary life or associate with other males in bull herds except rut. The "lateral display" is the striking behaviour pattern of the Indian bison and appears to one of the important means by which bull establishes the rank without actual physical contact.
