The guanaco is the largest wild mammal species found in South America. Guanaco herds usually consist of one dominant male and 5–15 adult females and their offspring. In addition there are separate herds consisting only of bachelor males and herds with only adolescent females. Young guanacos are a favourite prey of pumas. Llamas were bred from guanacos and alpacas are most probably a cross-breed between the guanaco and vicuna.
