The Gray Wolf is a deeply social animal running in packs of up to 12 animals. The animals of a pack are nearly always related by family ties and have a strict social hierarchy. The dominant male and female respectively are called the alpha male and alpha female and lead the pack. Every wolf in a pack knows its position in the pack and acts accordingly. Gray Wolves hunt in packs usually identifying old or injured prey animals and separating them from the herd.
Wolves usually bite the shoulders and flanks of the prey.
Some members of the pack harass the prey from the rear, while other members sieze the prey by the nose. Gray Wolves can eat up to 20 pounds of meat when it is available. It takes about 10 square miles of territory to feed one wolf. Although Gray Wolves are normally territorial, wolf packs may follow migrating caribou herds hundreds of miles in the arctic. Gray Wolf pups are born in the spring.
