Guanaco

The guanaco ("Lama guanicoe") is camelid animal native to South America. Guanacos are usually found in small herds or loosely structured family groups.
Description.
When a member of the herd picks up the slightest hint of danger, it makes a high-pitched warning call, causing the other guanacos to flee swiftly and nimbly across the steep and uneven terrain.
Diet.
Guanacos generally live at high elevations, grazing on grasses and browsing on leaves and buds.
They can get by without water for long periods of time, obtaining moisture from the plants they eat.
