Reindeer vs Caribou

Reindeer and caribou share one scientific name, Rangifer tarandus, so there is no biological split between them. The names follow geography and management. In North America the term caribou refers to most wild populations, while reindeer is the name for Eurasian populations and for animals kept in herds.

Because reindeer have been bred for centuries, herded animals can differ from wild ones in leg length, antler size and coat color. Reindeer coats are more varied, from tawny and white to brown and spotted, while caribou are more uniformly light brown with a white neck and underbelly. Treat those as tendencies, not rules.

When you are looking at which

Reindeer

• The animals are kept in herds by herders, a farm or a holiday display.
• The coat is varied, with white, tawny or spotted animals in one group.
• The setting is Scandinavia, Siberia or an Alaskan reindeer ranch.
• Calves were born in mid-April and are dark chocolate brown.

Caribou

• The animals are wild and skittish, living on tundra or boreal forest in North America.
• The coat is light brown with a white neck and underbelly.
• You are watching a long migration across open country.
• Calves are reddish-brown and born late May to June.

How this works

The quiz asks where you are, whether people manage the animals, coat variety, temperament and movement. These are the cues wildlife and park agencies use to explain why one species has two names, and the quiz keeps them simple so you can answer from a photo or a trip.

Because the species is the same, no cue is a hard rule. Wild reindeer exist in Eurasia, and herded animals in North America can look like caribou. Treat the result as the likely name, not a different animal, and expect some overlap in the wild.

Where these numbers come from

The figures and defaults on this page are based on:

• National Park Service: Reindeer vs. Caribou, Same species, domestication, calf timing, coats, migration and Alaska history (checked October 2026)
• San Diego Zoo Wildlife Alliance: Reindeer (Caribou), Naming, size, antlers on females, herd size and lifespan (checked October 2026)

Naming guide for one species; the name used depends on region and whether the animals are managed.
