Adaptations!

 A structural adaptation that the American Woodland Caribou has is their hooves.  The hooves of the American Woodland Caribou are like scoops so they can dig for food underneath the snow. This helps them compete for resources because it enables them to find food faster and easier than other organisms. Another structural adaptation that they have is their thick fur. Their thick fur makes it easier for them to live in colder climates. This would help them against other organisms because they would be able to stay in the same overall habitat.

A behavioural adaptation that the American Woodland Caribou has is that they migrate. They migrate to lower elevations in the winter and higher elevations in the summer. They do this because the conditions aren't as harsh in a lower elevation so it is easier for them to survive.
