About the Caribou

Caribou, also called reindeer, are found in northern regions of North America, Europe, Asia, and Greenland.

Migration

As summer approaches, caribou herds head north in one of the world's great large-animal migrations. They may travel more than 600 miles along well trod annual routes. At the end of their journey, they spend the summer feeding on the abundant grasses and plants of the tundra. In these rich grounds, an adult caribou can eat 12 pounds of food each day.

During migration, herds of cows (female caribou) leave several weeks before the males, who follow with yearling calves from the previous birthing season.

Hooves and Antlers

Caribou have large hooves that are useful tools for life in the harsh northlands. They are big enough to support the animal's bulk on snow and to paddle it efficiently through the water. The hoof's underside is hollowed out like a scoop and used for digging through the snow in search of food. Its sharp edges give the animal good purchase on rocks or ice.

Caribou are the only deer in which male and females both have antlers—though only some females have them. Cows have one calf each year, which can stand after only a few minutes and move on with its mother by the next day.

When the first snows fall each year, the caribou turn south and complete a migration that sees them travel as many as 1,600 miles each year. They spend the winter in more sheltered climes and survive by feeding on lichens.

Caribou are traditionally vital to indigenous northern people throughout much of their range.
