Two guanacos, Torres del Paine National Park, Chile

Prick up your ears and stretch your neck—let's step into the world of guanacos. These creatures, part of the same family as camels, alpacas and llamas, are native to the rugged landscapes of South America. Standing around 110 centimetres tall and weighing up to 90 kilograms, guanacos travel in herds led by a dominant male, accompanied by females and their young.
