Gray wolves, or timber wolves, are canines with long bushy tails that are often black-tipped. Their coat color is typically a mix of gray and brown with buffy facial markings and undersides, but the color can vary from solid white to brown or black. Gray wolves look somewhat like a large German shepherd. Wolves vary in size depending on where they live. Wolves in the north are usually larger than those in the south. The average size of a wolf’s body is three to five feet long and their tails are usually one to two feet long. Females typically weigh 60 to 100 pounds, and males weigh 70 to 145 pounds.

There are many different types of wolves. The grey, or timber wolf is found in the northern parts of North America. The female usually weighs between 50 and 85 pounds. The males are a little heavier, weighing in between 70 and 110 pounds.  A female grey wolf can get as long as between 4.5 to 6 feet. The males average 5 to 6 feet. The average height of a gray wolf is 26 to 32 inches.

For thousands of years, wolves have captured humanity’s imagination. While they may not be as large as lions or bears, wolves still fill people with fear. These sociable animals hunt in packs and are capable of bringing down prey much heavier than them. Their territory can spread over hundreds of miles, and packs can include up to 20 adult members. 

Features of Wolves

1. Gray wolves are the largest living wild canine species.

2. Wolves are the wild ancestor of all our domesticated dogs, from poodles to bulldogs to greyhounds.

3. Wolf packs usually hunt within a territory, which can range from 50 square miles (129 square kilometers) to over a 1,000 square miles (2,590 square kilometers).

4. Wolves often travel at five miles (8 kilometers) an hour, but can reach speeds of 40 miles (64 kilometers) an hour.

5. Wolves howl to solidify pack bonds and warn other wolf packs to stay away—but despite popular belief, wolves don’t howl at the moon.

Pack Behaviour

Gray wolves usually live in packs of up to two dozen individuals; packs numbering 6 to 10 are most common. A pack is basically a family group consisting of an adult breeding pair (the alpha male and alpha female) and their offspring of various ages. The ability of wolves to form strong social bonds with one another is what makes the wolf pack possible. A dominance hierarchy is established within the pack, which helps maintain order. The alpha male and alpha 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.

A pack’s territory can be 80 to 3,000 square km (31 to 1,200 square miles), depending on prey abundance, and it is vigorously defended against neighbouring packs. 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.

How Much Does A Wolf Weigh?

Wolves can weigh up to as much as 120 pounds. This weight can vary depending on the species, age, and gender of the wolf. Taking all species into account the general weight of a wolf is between 40 to 120 pounds.

Gray wolves are the larger species normally weighing between 50 and 120 pounds, and red wolves are the smaller species normally weigh between 50 and 85 pounds. An even smaller species, the Abyssinian wolf, which is still being debated whether it’s a wolf or not, normally weighs up to 30 pounds.

Why Do Wolves Howl?

Wolves howl to communicate with one another over long distances, whether it’s to locate pack members, defend territory, or just to sing with one another. A wolf’s howl can be heard up to 10 miles away, and each wolf has a unique howl distinct to that individual.

What Do Wolves Eat?

Wolves mostly prey on caribou, elk, white tail deer, moose, and bison, though wolves can eat fish and carrion as well. Captive wolves, such as those at California Wolf Center, eat a carefully balanced mix of fresh meat, fish, specially formulated kibble, nutritious soft food, and enrichment treats designed to maintain a varied and healthy diet.

How Many Wolves Are There In A Pack?

Wolf pack size can range from 2 to 36 wolves, with the average pack size consisting of 6 wolves. A pack usually consists of a breeding pair, their current offspring, and a few yearlings. There also may be a few related and/or unrelated adult wolves in the pack.

Wolves will usually stay with the pack until they are 2-3 years of age. At that time, they may choose to disperse to join a different pack or to start a new pack of their own. Pack sizes depend on the available prey and territory. Wolf packs in Alaska and Canada are usually larger than in the lower 48 states, which is mostly due to the abundance of prey and larger available range.

How Many Pups Do Wolves Have And How Long Is Their Gestation Period?

The gestation period for wolves is approximately 63 days, with most wolves giving birth between late March and early June. The average wolf litter consists of 5 pups, but these numbers can vary depending on the abundance of prey, wolf population density, and the size of available territory.

How do wolves communicate?

In addition to howling, wolves communicate in a variety of other ways. They make vocalizations such as growling, whimpering, whining, and barking, as well as make facial expressions, eye contact, body posture, and even scent marking.

Why Do Some Wolves Have Numbers Instead Of Names?

Wolves that are part of an active reintroduction program (like Mexican gray wolves) are referred to by their studbook number to avoid confusion within the program, as multiple wolves might have the same name. The letter denotes the sex of the animal (M=male, F=female) and the number corresponds to the order in which the wolf was entered into the program through birth in a breeding facility or discovery in the wild. For example, if the series of numbers is 1781, then that wolf is the 1,781st wolf entered into the program.

Wolves are entered into the program by being born in a captive breeding facility or counted and/or collared in the wild population.
