Timber wolves, also called gray wolves, are the largest wild members of the dog family, with males are usually bigger than females. Timber wolves have silvery gray-brown backs, light tan and cream underparts, and bushy tails. In winter, their fur becomes darker on the neck, shoulders, and rump. Wolves are social animals, living in a family group, or pack. A pack usually has six to ten animals: a dominant ("Alpha") male and female (the breeding pair), pups from the previous year (yearlings) and the current year's pups. Additional subordinate adults may join the pack upon occasion. The dominant pair is in charge of the pack, raising the young, selecting denning and rendezvous sites, capturing food and maintaining the territory. A wolf pack's territory may cover 20-120 square miles, thus wolves require a lot of space in which to live, a fact that often invites conflict with humans. While neighboring wolf packs might share a common border, their territories seldom overlap by more than a mile. A wolf that trespasses in another pack's territory risks being killed by that pack. It knows where its territory ends and another begins by smelling scent messages - urine and feces - left by other wolves. In addition, wolves announce their territory by howling. Howling also helps identify and reunite individuals that are scattered over their large territory.
