Ingo Arndt's Image

The guanaco turns, terrified, his last mouthful of grass flying in the wind as a female puma attacks. For Ingo, this is the culmination of months of work tracking wild pumas on foot, enduring extreme cold and biting winds. After an intense four-second struggle, the guanaco escaped with his life, leaving the puma to go hungry.

Because they are so abundant in Patagonia, guanacos are common prey of pumas. These big cats are solitary and hunt by patiently stalking before they pounce. Their robust hind legs allow them to take on animals bigger than themselves but they can also feed on smaller animals, such as rodents and birds.
