But wolves and humans have a long adversarial history. Though they almost never attack humans, wolves are considered one of the animal world's most fearsome natural villains.
They do attack domestic animals, and countless wolves have been shot, trapped, and poisoned because of this tendency. In the lower 48 states, gray wolves were hunted to near extinction, though some populations survived and others have since been reintroduced.
Few gray wolves survive in Europe, though many live in Alaska, Canada, and Asia. Wolves live and hunt in packs of around six to ten animals. They are known to roam large distances, perhaps 12 miles in a single day.
A dominance hierarchy is established within the pack, which helps maintain order. The alpha male and female continually assert themselves over their subordinates, and they guide the activities of the group.
The female predominates in roles such as care and defense of pups, whereas the male predominates in foraging and food provisioning and in travels associated with those activities.
Both sexes are very active in attacking and killing prey, but during the summer hunts are often conducted alone. Wolves communicate with one another by visual signaling facial expression, body position, tail position , vocalizations , and scent marking.
Howling helps the pack stay in contact and also seems to strengthen social bonds among pack members. Along with howling, marking of territory with urine and feces lets neighbouring packs know they should not intrude.
Intruders are often killed by resident packs, yet in some circumstances they are accepted. Breeding occurs between February and April, and a litter of usually five or six pups is born in the spring after a gestation period of about two months.
The young are usually born in a den consisting of a natural hole or a burrow, often in a hillside. A rock crevice, hollow log, overturned stump, or abandoned beaver lodge may be used as a den, and even a depression beneath the lower branches of a conifer will sometimes suffice.
All members of the pack care solicitously for the young. The pups grow rapidly and are moved farther and more often as summer comes to an end.
In autumn the pack starts to travel again within its territory, and the pups must keep up. Most pups are almost adult size by October or November.
After two or more years in the pack, many leave to search for a mate, establish a new territory, and possibly even start their own pack. Those who stay with the pack may eventually replace a parent to become a breeding animal alpha.
Wolves that leave their packs are known to have traveled as far as km miles. Wolves are renowned for their wide-ranging travels, and it is not unusual for them to cover 20 km 12 miles or more in a day.
They move and hunt mostly at night, especially in areas populated by humans and during warm weather. The main prey are large herbivores such as deer , elk , moose , bison , bighorn sheep , caribou, and musk oxen , which they chase, seize, and pull to the ground.
Beaver s and hare s are eaten when available, and wolves in western Canada even fish for Pacific salmon. A large percentage of the animals that wolves kill are young, old, or in poor condition.
After making a kill, the pack gorges consuming some 3 to 9 kg [7 to 20 pounds] per animal and then lingers, often reducing the carcass to hair and a few bones before moving on to look for another meal.
They mate in late winter. The female has a gestation period of nine weeks and gives birth to a litter consisting of one to 11 pups.
When the pups are born, they are cared for by all of the adult wolves in the pack. Young pups start off drinking milk from their mother, but around five to 10 weeks they will start eating food regurgitated from adult pack members.
At six months, wolf pups become hunters, and at 2 years old they are considered adults. On average, a wolf will live four to eight years in the wild.

Though wolves once roamed far and wide, they are very scarce today. The International Union for Conservation of Nature and Natural Resources IUCN lists red wolves as critically endangered.
According to the National Parks Conservation Association, there are 20 to 80 red wolves currently living in the wild. The Ethiopian wolf is also listed as endangered by the IUCN.
The Eastern wolf is threatened and is protected in Canada. Packs of wolves don't like to stay in one place.
They are known to travel as far as 12 miles 20 kilometers per day. Wolves have friends. Wolves howl to communicate with other members of the pack.
The first consists of the males, led by the alpha male and the other consists of the females, led by the alpha female. In this situation, the alpha male assumes the top position overall in the pack.
However, in some cases during the mating season the alpha female takes total dominance even while the pups are still in the den.
This is for the rest of the pack to know that she is the one to serve. She also decides were the den will be. With this in the packs mind, they go in search of food and bring it back to the den either for the hungry female or for the pups.
The male and female hierarchies are interdependent and are maintained constantly by aggressive and elaborate displays of dominance and submission.
Control of breeding rights is one of the key privileges held by alpha wolves. Alphas are usually the only wolves in the pack to breed and they actively and sometimes aggressively prevent other adult wolves in the pack from breeding.
If the other adults want to breed they usually have to leave their pack and set up elsewhere. Another privilege for the alpha pair is access to food.
When a large prey has been captured, they have first rights to eat as much as they want, along with their offspring pups. In times when food is scarce, the other adults in the pack may do better to disperse and fend for themselves.
However, wolves tend to feed amicably when food is ample. Beta wolves typically take on the role of raising the alpha pairs offspring, often becoming surrogate mothers or fathers to the pups while the alpha pair are absent.
Beta wolves are the most likely to challenge their superiors for the role of the alpha, though some betas seem content with being second and will sometimes even let lower ranking wolves push ahead of them for the position of alpha should circumstances make it necessary for this to happen death of the alpha, etc.
More ambitious betas, however, cannot wait for the top spot and will challenge the alpha sooner or disperse from the pack to create one of its own.
Sometimes, if the alpha is an aging wolf, he will give up his position submissively and allow the beta to take his place.
Healthier alphas will fight his challenger intensely to keep his lead roll, sometimes resulting in each one being injured. The loser is usually chased away or may be killed as other aggressive wolves contribute to the opposition.
This kind of dominance encounter is more common during the mating season. Wolves prefer psychological warfare to physical confrontations, meaning that high-ranking status is based more on personality or attitude than on size or physical strength.
Rank, who holds it, and how it is enforced varies widely between packs and between individual animals. In large packs full of easygoing wolves, or in a group of juvenile wolves, rank order may shift almost constantly.
Wolves howl for many reasons. Wolves howl as a way of communicating with other wolves. Wolves howl when they are rallying for a hunt, mourning, communicating with another pack of wolves or when a pack member has become separated — a lost wolf howls and the other members of his pack respond, giving him a sound to guide him home.
Pack members recognise each others voices. Howling can also serve as a declaration of territory or a sign of protection such as protecting a fresh kill.
Large packs of wolves will howl more than smaller packs of wolves. This is because smaller packs do not want to draw un-necessary attention to themselves.
Adjacent packs may respond to each others howls, which can mean trouble for the smaller of the two.
Therefore, wolves tend to howl with great care. Wolves howl at various levels of tones and pitches which tends to prevent a listener from accurately estimating the number of wolves involved.
This concealment of numbers makes a listening rival pack wary of what action to take. For example, confrontation could mean bad news if the rival pack gravely underestimates the howling packs numbers.
People have often guessed, based on listening to howls, that a pack of wolves contained up to 20 individuals, when there were only 3 or 4.
Wolves tend to howl the most during the twilight hours, usually before the adults go and hunt and on their return. Wolves also tend to howl more during their breeding season and throughout rearing of pups.
The wolf pups in turn will begin to howl and will be provoked into howling sessions quite easily.
Such random howling usually has a communicative intent and has no adverse consequences so early in a wolfs life.Kleinere Säuger wie Feldhasen, WildkaninchenLemminge und andere Wühlmäuse Sous Vide Ribs ebenfalls erbeutet.
