The caribou migration is the longest land migration on planet Earth. Joining the arctic tern and humpback whale who hold the respective records in air and sea, the caribou (Rangifer tarandus) walk 2,000 miles each year between their winter and summer grounds.
Where do caribou migrate?
Some herds of caribou migrate between 1,250 and 1,350 kilometers in Canada and Alaska each year to get from their wintering grounds to breeding grounds and back again.
What time of year do caribou migrate?
Mid-winter is the time of energy conservation for caribou and is when movement rates are lowest. Depending on weather and snow conditions, caribou begin their northward spring migration in early April (Joly and Cameron 2017), back toward the calving grounds.
What is the distance of the caribou migration?
They found that caribou migrate about 745 miles a year round-trip, clocking in at the longest terrestrial migration. (Whales and birds migrate much farther by sea and by air.) But the researchers also found that for sheer distance traveled, gray wolves trek farther every year.
Do caribou and reindeer migrate?
Wild reindeer and arctic caribou are migratory, and their habitat crosses territorial and national borders. As the climate changes, and migration patterns shift, it will be increasingly important for governments to implement plans that support wildlife and ecosystems.
When and where do caribou migrate?
Caribou migrate with the seasons. They travel to the fertile coastal plains to give birth then move farther north to escape plagues of mosquitoes. Finally, they move back south to warmer areas as winter approaches. Caribou are also known by the more familiar name of reindeer.
Where do reindeer migrate to?
Tundra reindeer spend winter dispersed in forests but aggregate in spring to migrate onto the tundra; in fall they mass again to return to the forest.
What triggers caribou migration?
Weather conditions are the main cues for fall migration.
Fall migration is determined largely by the weather conditions caribou experience. Generally, when caribou experience colder temperatures and the first snowfall, that is their cue to start migrating.
What country do caribou live?
Caribou live in the arctic tundra, mountain tundra, and northern forests of North America, Russia, and Scandinavia. The world population is about 5 million.
What is reindeer migration?
Typically reindeer are in the habit of migrating seasonally. They are on the move at all times, spending the late spring and summer on the arctic tundra or coast and moving inland to the boreal forests of the taiga for the winter.
