| Gray wolves usually live in packs, led by an "alpha pair." The pack includes some of the alpha pair's offspring and may include some unrelated wolves. A pack's territory can be as large as 13,000 square km. Howling probably helps advertise who "owns" a particular piece of territory. When pups are born, the mother stays near them for the first three weeks, and her mate and others in the pack bring food to her. The pups are weaned when they about nine weeks old. As adults, they may travel as far as 72 km a day with their pack and run as fast as 70 km per hour.
