Wolves are highly social creatures, preferring to gather together in packs. A pack usually consists of a mother wolf, father wolf, and their children. A wolf pack may also consist of multiple families.
Wolves are territorial animals that spend their days traveling their chosen territory, hunting for prey. A pack will fiercely defend its territory from other packs.
Wolves are very vocal, and are known for their howls, which they use to draw the pack together and alert pack members of potential threats. Wolf howls can be heard over a range of 50 square miles.
Wolves are expert hunters, and packs can bring down much larger animals, including elk, moose and bison. Even individual wolves can occasionally handle these large animals on their own. However, large prey animals can prove dangerous for wolves to hunt, and they can be seriously injured or even killed by elk, moose, bison, muskoxen, and white-tailed deer.
Other less dangerous prey animals include geese and large birds, beavers, and hares and rabbits.
Wolves are monogamous animals, and a mated pair typically stays together for life and forms the foundation for the pack. Female wolves will create dens for their pups, either using existing natural structures like caves or cliffs, or burrows of other animals like foxes or badgers.
Pregnant wolves remain in the den, and give birth after about two months of gestation. A younger wolf may bear four or five pups, while older mothers may give birth to as many as eight or more. Pups are born unable to see or hear, and only open their eyes nine to twelve days after birth. Pups born in springtime will be mature enough to help their parents on hunts by the fall season.
Wolves are the largest canid species, growing to over 5 feet long and just under 3 feet at the shoulder. Their fur is usually a mix of gray, white, brown and black, although the Arctic subspecies is often almost entirely white-furred.
Wolves are powerful apex predators with sharp canine teeth and strong jaws.
Wolves are common in folklore and mythology of many cultures. Ancient Romans believed their city was founded by Romulus and Remus, two brothers who were raised by a wolf mother. Ancient Norse myths tell of the giant wolf named Fenrir (or Fenris) that will help bring about the end of the world.
North American Indigenous peoples including the Pawnee and Blackfoot call the Milky Way galaxy the “Wolf Trail”, and it is culturally significant to many tribes and clans in the Pacific Northwest.
The wolf is also a prominent fixture in many fables and cautionary tales told to children, including “The Boy Who Cried Wolf”, “Little Red Riding Hood”, and “the Three Little Pigs”. The popular expression, “wolf in sheep’s clothing” refers to someone with negative intentions who pretends to be harmless.
Wolves are considered a species of Least Concern, with global populations mostly holding steady. It has been reintroduced to many areas of its historical range. Wolves have often butted heads with farmers and others in rural areas, due to their predation on livestock. The overhunting of bison, a key prey species of wolves, also contributed to a decline in their population. In 1973 they were granted protected status in the USA, and their population has rebounded.
