Wolves are among the most misunderstood of wild predators. They are not at all aggressive towards humans. There is not one substantiated case in North America of a wild wolf ever attacking a human. Wolves are very social, with tight bonds between members of their pack. Other females in a pack will often tend to cubs while the mother goes hunting. Members of a wolf pack will show great affection towards one another.

endangered species books on animals training macawsI was blessed for thirteen years to share time and space with a Canadian timber wolf named Cleo. She died September 28, 2002. She was a kind and gentle companion. I got her when she was 5 weeks old and raised her much as an adult wolf would raise a pup. She was never asked to do anything other than be a wolf. I never attempted to train her in any way in the normal meaning of the word. Yet, she would do so many things to please me and conform to my lifestyle that I was constantly amazed at her sensitivity and desire to accommodate me.

We would lie down watching television for hours, her body next to mine and her loving amber eyes watching me for assurance that she wasn't doing anything to upset me. Although a wolf's bite is a bone-crushing 1500 pounds per square inch, twice that of a German shepherd for instance, she was so gentle with me that I can't recall her ever breaking my skin when she was playfully mouthing me.

While I would never allow young children to be in proximity to any wild animal, Cleo was quite safe to be in the company of friends of mine, under careful supervision. If she didn't feel comfortable around a stranger--which happened about half the time--she would simply stay a reasonable distance from that person. Wolves are actually rather shy animals, always preferring to avoid a conflict.

A wolf's intelligence level is quite a bit higher than that of a dog. Once Cleo met someone that she liked, that person could come to my house years later and Cleo would remember them immediately, rushing up and putting her paws on their shoulders and showering them with licks. While I frequently had to tell friends that mouth-licking is how members of a wolf pack greet one another, needless to say some of my friends never quite wanted to become that much like a wolf.

Cleo had a playmate when she first arrived; a very large male German shepherd named Caesar. Caesar became very ill about four years later and had to stay in my bedroom for several months until he ultimately died. Before taking him for burial, I brought Cleo up to see him one last time. She sniffed him, looked at him, then sat back and commenced to make long, soulful howls unlike anything I have heard from her before or since that day.

Here are some of the characteristics of wolves:

There are three species of wolves in the world: the gray wolf (Canis lupus), the red wolf (Canis rufus) and the Ethiopian (or Abyssinian) wolf, (Canis simensis). Some researchers believe the Ethiopian wolf is not a wolf, but actually a jackal.

The gray wolf, Canis lupus, lives in the northern latitudes around the world. There are five subspecies of the gray wolf in North America and seven to 12 in Eurasia.

All living wolves are considered a single species, with the exception of the red wolf of southeastern Texas and southern Louisiana. The gray wolf is the largest of the wild dog family. There are 32 recognized subspecies of gray wolf. They get up to about 175 pounds, and the most common color is grizzled gray.

Subspecies are often difficult to distinguish from one another. This is because they interbreed where their ranges overlap so that their populations tend to blend together rather than form distinctive boundaries. The different traits we see in subspecies are likely the result of geographic range, available habitat, and prey base. Skull dimensions, overall size, fur color, and the length of appendages are some of the characteristics that differ between subspecies of gray wolf.

Members form strong social bonds that promote internal cohesion. Order is maintained by a dominance hierarchy. When two wolves meet, each shows its relationship to the other by indicating dominance or submission through facial expression and posture. Other modes of wolf communication that we know are howling, other vocalizations, and scent marking. One of the functions of howling is to communicate position or assemble the pack; advertisement of territory to neighboring wolves is another. Scent marking is done by depositing urine or feces on objects along travel routes, particularly at the edge of the packs' territory. This appears to functions as territory boundary marking and intrapack communication. Usually only the highest ranking male and female within a pack will breed. Other female members of the pack act as aunts, frequently caring for the pups throughout their childhood.

Pack size is highly variable because of birth of pups, dispersal, and mortality. Generally, a gray wolf pack has from six to eight wolves, but in Alaska and northwestern Canada some packs have over 30 members.

Red wolf packs are generally smaller than gray wolf packs and usually have 2 to 8 members, but a pack of 12 is known in the wild.

Territory size is highly variable. Gray wolf territories in Minnesota range from about 25 to 150 square miles, while territories in Alaska and Canada can range from about 300 to 1,000 square miles.

Red wolf territories can be from 10 to 100 square miles, but the territories of red wolves reintroduced into North Carolina have been 38 to 87 square miles.

Wolves breed at slightly different times, depending on where they live. For example, gray wolves in the Great Lakes Region breed in February to March, while gray wolves in the Arctic may breed slightly later in March to April.

Red wolves usually breed in January or February.

The gestation period of gray and red wolves is usually around 63 days.

A pack normally has only one litter of pups each spring, but in areas of high prey abundance more than one female will give birth in each pack. An average litter size for gray and red wolves is 4 to 6, but several may die if natural prey is not readily available.

Gray wolf pups weigh 1 pound at birth, while red wolf pups weigh less than a pound at birth.

Adult female gray wolves in northern Minnesota weigh between 50 and 85 pounds, and adult males between 70 and 110 pounds. Gray wolves are larger in the northwestern United States, Canada, and Alaska where adult males weigh 85 to 115 pounds and occasionally reach 130 pounds.

Adult female red wolves weigh 40 to 75 pounds, while males weigh from 50 to 85 pounds.

The average length (tip of nose to tip of tail) of an adult female gray wolf is 4.5 to 6 feet; adult males average 5 to 6.5 feet. The average height (at the shoulder) of a gray wolf is 26 to 32 inches.

The average length (tip of nose to tip of tail) of an adult red wolf is 4.5 to 5.5 feet. The average height (at the shoulder) of an adult red wolf is about 26 inches.

The size of a wolf's track is dependent on the age and size of the wolf, as well as the substrate the track was made in. A good size estimate for a gray wolf's track size is 4 1/2 inches long by 3 1/2 inches wide. In comparison, a coyote's track will be closer to 2 1/2 inches long by 1 1/2 inches wide. Only a few breeds of dogs leave tracks longer than 4 inches (Great Danes, St. Bernards, and some bloodhounds).

Adult gray and red wolves have 42 teeth, while adult humans have 32.

The biting capacity of a wolf is 1,500 pounds of pressure per square inch. The strength of a wolf's jaws makes it possible to bite through a moose femur in six to eight bites. In comparison, a German shepherd has a biting pressure of 750 pounds per square inch. A human has a much lower biting pressure of 300 pounds per square inch.

Gray wolves prey primarily on large, hoofed mammals such as white-tailed deer, mule deer, moose, elk, caribou, bison, Dall sheep, musk oxen, and mountain goat. Medium sized mammals, such as beaver and snowshoe hare, can be an important secondary food source. Occasional wolves will prey on birds or small mammals.

Red wolves primarily prey on white-tailed deer, raccoons, rabbits and rodents.

Gray wolves can survive on about 2 1/2 pounds of food per wolf per day, but they require about 5 pounds per wolf per day to reproduce successfully. The most a gray wolf can eat in one sitting is about 22.5 pounds.

Red wolves eat an average of 5 pounds of food per day, but have been known to eat up to 12 pounds in one sitting.

In Minnesota, wolves kill the average equivalent of 15 to 20 adult-sized deer per wolf per year. Given the 1997-98 estimate of 2,450 wolves in Minnesota, that would equal about 36,750 to 49,000 deer killed by wolves. In comparison, from 1995-1999 hunters killed between 32,300 to 78,200 deer each year in Minnesota's wolf range. In addition, several thousand deer are killed during collisions with vehicles each year.

Gray wolves in the wild have an average life span of 6 to 8 years, but have been known to live up to 13 years in the wild and 16 years in captivity. Red wolves in the wild have an average life span of 8 to 9 years, but have been known to live up to 12 years in the wild and 16 years in captivity.

The natural causes of wolf mortality are primarily starvation, which kills mostly pups, and death from other wolves because of territory fights. While not usually a big problem, disease such as mange and canine parvovirus can be a concern in small and recovering populations. Injuries caused by prey results in some deaths. Human-caused mortality including legal, illegal, and accidental causes, can be high in some populations. Pup mortality rates are highly variable, but approximately 40 to 60% of wolf pups die each year.

Wolves will travel for long distances by trotting at about five miles per hour. They can run at speeds of 25 to 35 miles per hour for short bursts while chasing prey.

Wolves may travel 10 to 30 miles each day in search of food. Dispersing wolves, those leaving packs in search of their own mate, have been known to travel distances of 550 miles away form their home territory.
