In the wild it can live seven to eight years, and up to 20 in human care. Size alone will not catch dinner. Hunting wolves can reach up to 38 miles per hour (61 kilometers per hour), and by working together a pack can take down prey larger than themselves, including caribou, moose, deer and bison. Packs often go after the old, young or sick in a herd, since they are easier to kill. When it finds food, a wolf can "wolf down" 20 pounds (9 kilograms) in one sitting, because the next meal might be days away. ## The Pack Runs on Rank and Howls A wolf pack is usually five to eight animals, though groups as large as 36 have been reported. Typically only the dominant pair breeds, sometimes staying together for life, while every member of the pack helps care for the pups. Depending on habitat and prey, a pack's territory can range from 40 to 1,000 square miles (about 100 to 2,600 square kilometers), and wolves constantly patrol and scent-mark it. > **A Howl Built to Travel** On Arctic tundra a gray wolf's howl can carry up to 10 miles, keeping a scattered pack together, kick-starting a hunt, and marking territory for other packs to hear. ## Tundra to Desert, and a Comeback in the Rockies Gray wolves once ranged across the majority of the Northern Hemisphere. Today the species still circles the globe through North America, Europe and Asia, in habitats from tundra and taiga to mountains, grasslands and deserts. Predator-control programs wiped wolves out of most of the contiguous United States in the early 1900s. In 1978 the government reclassified the gray wolf as endangered across the contiguous states and Mexico, with Minnesota's wolves listed as threatened. It delisted the Northern Rocky Mountains population in 2011 (Wyoming followed in 2017). Globally, the species is now rated Least Concern. Even where wolves are common, attacks on people are extremely rare: they have happened in Eurasia, and North America has had only four reported attacks, none of them fatal. ## The Wolves That Fish for Salmon Some of Alaska's coastal wolf packs fish for salmon. A biologist studying wolves on Prince of Wales Island watched them wade into shallow tidal streams to catch pink and chum salmon as the runs came in. Chemical analysis of wolf bone showed salmon makes up around 20 percent of the diet for wolves on the coastal mainland and the island, and about 25 percent for some of the island's wolves, against about 10 percent for wolves in Alaska's Interior. That bonus food is especially important for pups. In Southeast Alaska he has noticed 90 percent of pups surviving, against half dying in their first summer in places like Minnesota, and he thinks salmon may play an important part in that. ## Frequently Asked Questions ### How big is a gray wolf pack's territory? Depending on habitat and how much prey is around, a pack's territory can range from 40 to 1,000 square miles (about 100 to 2,600 square kilometers). Wolves patrol and scent-mark their home turf, and howling also marks the pack's boundaries. *(Source: [San Diego Zoo Wildlife Alliance]())* ### Can a gray wolf really crack open bones with its jaws? Yes. A gray wolf's jaws are strong enough to bite through tough hide, and it can break open hard bones in just a few bites. *(Source: [San Diego Zoo Wildlife Alliance]())* ### How far can a gray wolf's howl travel, and why do wolves howl? On Arctic tundra, a howl can carry up to 10 miles (16 kilometers). Wolves howl to rally the pack before a hunt and to keep in touch when separated, and howling warns other wolves to stay away from a pack's boundaries. *(Source: [San Diego Zoo Wildlife Alliance]())* ### Do gray wolves really eat fish? Some do. A biologist studying wolves on Alaska's Prince of Wales Island watched them wade into shallow tidal streams to catch pink and chum salmon. Chemical testing of wolf bone found that salmon makes up around 20 percent of the diet for wolves on the island and on Southeast Alaska's coastal mainland, and about 25 percent for some of the island's wolves, against about 10 percent for wolves in Alaska's Interior. *(Source: [Woodford, Riley 2004]())* ## Sources 1.
