Canada/Nunavut: Barren Ground Caribou migration

Barren ground caribou is a sub-species of caribou endemic to Nunavut and central Canada. While most other caribou herds in North America are being depleted to near extinction, the herd in Nunavut is still going over 300,000 strong. Every year, they migrate hundreds of kilometers to their calving ground over frozen terrain of lakes and treeless tundra, making it one of the largest migrations on Earth. Groups of dozens to hundreds of animals cover insane distances, stopping to dig out lichen from under snow and ice, on their way north. Wolverines, wolves, and bears thin them out along the way. Following the migration in snowmobiles, we clocked almost a hundred km per day to witness the spectacle of this migration.
