Reindeer

Reindeer, or caribou in North America, are a species of deer native to Arctic, subarctic, tundra, boreal, and mountainous regions of the Northern Hemisphere.

Updated August 1, 20261 min readCited sources

Reindeer, also called caribou in North America, are the only deer species where both males and females grow antlers. They inhabit Arctic and subarctic regions across the Northern Hemisphere.

What it is

Reindeer and caribou are the same species, Rangifer tarandus, in the deer family. In North America, wild populations are typically called caribou, while domesticated or semi-domesticated animals are referred to as reindeer.

Why it matters

Reindeer have been domesticated in parts of Europe and Asia, providing transport, meat, milk, and hides. In Canada, wild caribou are ecologically significant and vital to many Indigenous communities for food, clothing, and cultural knowledge.

Key details

Reindeer are herbivores feeding on grasses, mosses, and lichens. They live in herds and many populations undertake long seasonal migrations. Both sexes grow antlers, and their thick coats and broad hooves are adapted for cold, snowy environments.

In short

  • Reindeer and caribou are the same species.
  • Both males and females grow antlers.
  • Found across northern Europe, Asia, Greenland, Alaska, and Canada.
  • Some populations are domesticated for transport and resources.
Canadian angle

Reindeer are significant in Canada because wild caribou are part of Canadian wildlife and ecology, especially in northern and Arctic regions. The species is also important to many Indigenous communities for food, clothing, transport, and cultural knowledge.
