They are called woodland caribou. The other is called barren-ground caribou. They live in the frozen tundra, far up north. They live where it is cold for nine months. A baby caribou is called a fawn.
Fawns can move about as soon as they are born.
In about 2 hours a fawn can walk several kilometers. A day old fawn can run faster than a man. Caribou have a lot of enemies like grizzly bears, lynx, and wolverines. But wolves are their main enemy. Groups of wolves often follow a herd of caribou waiting to catch a calf, or a sick or old member of the herd.
