Guanacos: describe one adaptation of this animal

The guanaco is camelid native to South America, closely related to the llama. Its name comes from the Quechua world huanaco. Young guanacos are called chulengos. One of the adaptation of this animal is to socialize. They are garrulous folk, living in herds usually composed of up to ten female, their young, and one dominant male. Baby guancos are adorable and the little four-legged ones can walk competently only five minutes after birth. Female guancos have a lengthy  eleven-and-a-half month gestation period, after which a single chulengo is born between  the South American summer months of December and March.
