The total size of the group's home range is between 500 and 600 hectares. [13] This requires efficient territorial defense mechanisms. A few of these include specific vocalizations, wagging of the tail, and erection of the hair. [11] The bright red facial skin is a sign of good health and allows for the determination of a healthy mate. [14]
