Torres del Paine National Park, Chile
Caribou migration, lekking Andean cock-of-the-rock and pumas
The powerful and predatory puma is shy, solitary and usually hunts at twilight. From October to May they roam across the mountains in search of guanacos (close relatives of llamas), but when the cold bites in winter (June to September) their prey moves to lower levels to feed on grasses and shrubs not covered in snow and the large felines follow. To track pumas at this quiet time of year in the park, you need to get up early (the cats are most often spotted at dawn and dusk), and wear plenty of layers (expect freezing temperatures). A sighting of this elusive big cat is not easy to achieve but an experienced tracker will give you the best chance.
