Known in Europe and Asia as reindeer, the caribou is the only species of deer in which both sexes bear antlers. Males lose them in the spring; females lose them when they give birth in June.
Eight subspecies are recognized, each varying in size, shape, and color.
Huge herds spend the winter feeding in boreal forests. In the spring, they migrate hundreds of miles north to calving grounds in the tundra.
They wander all summer, feeding on leaves of small shrubs, aromatic plants, grasses, sedges, fungi, and lichens; in the fall, they breed.
In Europe, they have been domesticated and are used to pull sleighs since their broad hooves are suited for walking in deep snow.
