Mackenzie Valley Wolf

The Mackenzie wolf goes by many names, but their inherited genetics from the wolves before them make them one of the top hunters in the entire world.

Their gray and white coat keeps them warm and hidden from anything they hunt, while their strong neck and jaw can take even the largest game (like bison and ox) down quickly. In spite of the wolves ‘ superior hunting techniques, they may still be attacked by bears and other wolves during their hunts.

3 Incredible Mackenzie Valley Wolf Facts!

Though there are approximately 40,000 Mackenzie Valley wolves around today, they are quite an interesting breed. Here are a few facts about the apex predator that roams the northwest region of the Americas.

• The Mackenzie Valley wolf goes by many names, including the Alaskan timber wolf, Canadian timber wolf, Northwestern wolf, and the Rocky Mountain wolf.
• Though this wolf typically is gray or black, their coat can also be white, tan, or blue.
• The Mackenzie Valley wolf has a frame that makes it one of the best wolves in the world at hunting.

Scientific Name

The Mackenzie Valley wolf is most commonly called the Northwestern wolf, but they have many other names that they go by as well, like the Alaskan timber wolf, the Canadian timber wolf, and the Rocky Mountain wolf. They are part of the Canidae family in the Mammalia class. Though they do not have any subspecies of their own, their subspecies is the Canis lupus occidentalis, which is also their scientific name.

While “Canis lupis” is simply the scientific name for the wolf species as a whole, they are differentiated with “occidentalis.” This name was given to the species by Sir John Richardson in the early 1800s. The Scottish naturalist noted that, while it would be easy to label the species by their distinct color, “occidentalis” was used to refer to the location where the wolf is found in. The word literally translates to meaning “of the western regions,” referring to their native North American habitat.

Evolution And Origin

The Mackenzie Valley wolf is a subspecies of the gray wolf and is also considered one of the rarest wolves in the world. The forefather of the gray wolf was Canis lepophagus, who lived in North America during the early Pliocene era, 2.5 to 5.3 million years ago. It is believed that this early canid was the ancestor of both the wolf and the coyote.

Appearance

The appearance of the Mackenzie wolf is rather distinct. After all, the genetics of the wolf is the influence behind many domestic dog species. This particular wolf species has a bristly but thick coat, helping them to survive during the brisk winters of the Northwest region of the United States and Canada.

While their coat is sometimes white, the most common colors are gray and black. They are also found in tan and blue, depending on the region that they need to remain hidden in. Their multicolored appearance helps them to hide amongst forest areas as they hunt in their groups, which are also known as packs.

These wolves – also known as the Canadian timber wolf or the Alaskan timber wolf – have an incredibly strong and powerful neck to support their head. The head tends to be rather heavy and powerful, filled with sharp teeth that can overpower any of their prey. In fact, the reason that this animal is so large is because of the plentiful prey available in their habitat.

Males are larger than females with a weight of up to 187 lbs. in some areas. Females, on the other hand, typically don’t weigh more than 132 lbs.

Behavior

Like most other canids, Mackenzie Valley wolves live in packs. These packs, however, resemble families of 6-10 individuals, in that they are composed of a breeding pair and their offspring from the previous breeding seasons. “[T]he typical wolf pack is a family, with the adult parents guiding the activities of the group in a division-of-labor system in which the female predominates primarily in such activities as pup care and defense and the male primarily during foraging and food-provisioning and the travels associated with them,” writes research scientist L. David Mech in the Canadian Journal of Zoology.

This notion of an ultra-aggressive, hyper-masculine alpha wolf that strong arms the rest of the individuals in the pack persists, even though it has long been debunked. The myth of the alpha wolf stems from studies in the mid-20th century of unrelated wolves in captivity. In such scenarios, adult wolves without any familial ties and stressed due to confinement were placed together. Their behavior was not indicative of what would be observed in the wild.

Habitat

Just like the common name of the Mackenzie Wolf (i.e., the northwestern wolf) suggests, the main home of this animal is the northwest area of North America. They can be found as far north as Alaska, though they are also found in the Canadian provinces of British Columbia, Alberta, and Saskatchewan. Sometimes, they will travel as far south as the northwest region of the United States.

Once the Mackenzie wolf establishes the home that they have chosen, it can be territorial of the area. They typically inhabit areas with massive forests or mountain areas. They flourish in the cold, which is what their coat is made to withstand.

Predators And Threats

Many of the habits of wolves focus on hunting at night for their prey. They are carnivorous, seeking out other animals as their source of nutrients. About 10 hours a day are spent looking for prey that can feed the wolf and their pack. They are apex predators, but they still have a few predators that will come after them (like humans and bears).

What Eats And Hunts Mackenzie Wolves?

Even as an apex predator, the Mackenzie wolf is not entirely safe. Apart from being hunted by humans, combat between this mammal and bison or bears can lead to their death. For the most part, the wolves can roam without the threat of other animals unless they directly attack them.

What Does The Mackenzie Wolf Eat?

The physique of the Mackenzie Valley wolf (or the Rocky Mountain wolf) makes them one of the top hunters in the world, which is why they have so many options to prey on. Due to their habitat in forests and mountains, the most common diet includes mountain goats, Dall sheep, lemmings, salmon, elk, musk oxen, snowshoe hare, wood bison, caribou, and even Sitka black-tailed deer. Sometimes, they’ll feed on beavers too.

The powerful teeth and strong muscles of the Mackenzie Valley Wolf (a.k.a. the Rocky Mountain wolf) are enough to take any of these animals down.

Reproduction And Life Cycle

While much of the species thrives on the ability to procreate, the Mackenzie Valley Wolf is a monogamous species. However, their breeding habits are rather unique because the pack only has one breeding pair. The pair is based on the oldest, strongest, and largest wolves in the pack, which may be a matter of genetically selecting the best chance of survival.

Most often, the mating season will occur in January and February, and the female will remain pregnant with her pups for about 63 days. Once the litter is born, she typically will give birth to 4-6 live young, which are also known as pups or whelps. These pups are protected within a den, protecting the defenseless pups while their hearing and sight develop (which can take up to 2 weeks). While the pups will explore beyond the den as early as 3 weeks old, they will need their mother’s milk until they are about 8 weeks old.

The pups will become adults between 6-8 months old. However, their body is not ready to reproduce until they are almost 2 years old as females. Males take approximately one more year before they are ready to reproduce. The average lifespan of these wolves is typically 6-8 years in the wild. However, animals in captivity may live twice as long for their protection from predators and consistent habitat.

Population

The main threats to the Mackenzie Valley wolf aren’t other predators, though there are a few larger animals that may hunt them. The loss of their habitat is the biggest cause of their depleting numbers. Humans will also hunt and trap these wolves, which is why less than 50,000 exist in Canada today.

An official population number is not currently provided by the IUCN Red List, but these wolves are endangered. The population’s attacks on local deer and elk help to naturally control these species, which benefits the overall ecological balance.
