Their primary prey include deer, moose, and caribou, although they frequently eat small mammals. Rodents from a major part of their diet. They will also eat various kinds of plants to get needed vitamins and minerals. Wolves have good hearing and a well developed sense of smell. This helps them find prey in their forested environment.
Wolves have sharp eyesight.
A wolf can run at 30 mph. When wolf packs hunt, they often set up ambushes to catch prey. They cull out weak or sick animals as they don't have the speed to run down a healthy deer. The pack will charge a group of deer and quickly determine which is the weakest one. That is the animal they will try to catch.
