In the summer caribou eat mostly grass and leaves of willow dwarf birch and other shrubs. In the winter, they survive on mostly lichens and springs. The caribou, along with other animals, live in the swamp like plains. To show alarm, the male raises his tail. As a sign of caution it thrusts one of its hind legs to the side.
Reindeer are normally smaller than the caribou.
For years the caribou have been hunted by the northern Indian and the Eskimos for meat and to make soup out of the marrow. The Indian and Eskimos made tents out of the caribou's hide. Although the caribou does not hunt for itself, it eats mostly willow dwarf birch and other shrubs. The caribou are hunted by other humans to make tents, sleeping bags and other materials. The physical features are their broad antlers and their cloven hoofs.
