The relationship between wolves and humans is long and complex. Although ancient wolves are the ancestors of today's domesticated dogs, over time wolves have come to be seen as violent predators.
Wolves live in a variety of habitats as they move from place to place. Where food is scarce, there are not many wolves. Wolves can be found easily where food is plentiful. Wolves will live in dens made of hollowed out tree trunks, caves, thickets, and holes dug into the ground.
Wolves live in groups called packs. A pack may contain up to 30 wolves, but rarely does. Most consist of eight wolves, not including the young. Each pack has a leader called an alpha. The alpha is occasionally female, but is usually male. The alpha male communicates with the other wolves roughly and strongly, showing its dominant power. The alpha wolf will not let the other wolves mate because the stronger the parent wolf, the stronger the pups. Under the alpha wolf is the beta wolf. The beta wolf, however, is not much different than the other wolves.
As it is nocturnal and has poor eyesight, the aardvark is cautious upon leaving its burrow. It comes to the entrance and stands there motionless for several minutes. Then it suddenly leaps out in powerful jumps. At about 30 feet out it stops, raises up on its legs, perks up its ears and turns its head in all directions. If there are no sounds, it makes a few more leaps and finally moves at a slow trot to look for food.
Wolves enjoy a variety of meats. They mostly eat caribou, bison, elk moose, and deer, but they also eat foxes and eggs, and small rodents such as hare, beaver, muskrats, and birds. They may eat some berries, grass, and other vegetable and fruit matter. The grass will purge their digestive system when they eat something that upsets their stomach. Beaver can make up 60% of the wolves' diet during the summer.
