Guanaco

The guanaco is a wild camelid of South America and the largest native land mammal in many of the habitats where it lives. Herds of guanacos are a classic sight in Patagonia.

Interesting facts

  • Guanacos live from the dry Atacama Desert to the windy grasslands of Tierra del Fuego.
  • Their blood carries oxygen efficiently, helping them live at high altitudes.
  • Guanacos give a high-pitched, laughing alarm call.
  • Young guanacos, called chulengos, can walk within minutes of birth.
  • Most of the world’s guanacos live in Argentina.
  • They can swim well, crossing rivers and channels.

Behaviour

Guanacos live in family groups of one male with several females and young, in bachelor groups, or alone. Males defend territories and use shared dung piles as markers.

Breeding and young

After about 11 months, a single chulengo is born, usually in summer.

Threats and conservation

Guanacos are common in Patagonia, but they have disappeared from much of their former range because of hunting, fences and competition with sheep.
