Besides its large chest, which also enhances balance, the wolf has a large neck that supports its big head that it uses during hunting. [8] The subspecies was first written of by Scottish naturalist Sir John Richardson in 1829. It is bigger than its canid family members like the fox, jackal, and coyote. The Mackenzie Valley Wolf has a specialized body that has made it one of the world's most efficient hunters. [13][14] Sir John Richardson described the northwestern wolf as having a more robust build than the Eurasian wolf, with a larger, rounder head and a thicker, more obtuse muzzle.

The gray wolf, scientifically known as Canis lupus (c.l), is the largest existing member of the Canidae family. The gray wolf also has other subspecies.

They usually stampede the herd using pack teamwork to separate the younger elk from the adults. In British Columbia, Canada, five adult females averaged 42.5 kg (94 lb) and ten adult males averaged 56.1 kg (124 lb), with a weight range for all adults of 38.6 to 69.4 kg (85 to 153 lb). [12], Based on known reported adult average body masses, this would make the northwestern wolf the largest-bodied wolf subspecies. [1], In Yellowstone National Park, artificially relocated northwestern wolves have been well-documented feeding on elk. Gray wolves have blunt ears and muzzles and they also have wide foreheads and mighty jaws.

Though the Guinness book of Animal World Records mentions an unconfirmed specimen weighing 230 pounds. C. l. occidentalis, the most northwestern subspecies, is descended from the last gray wolves to colonize North America. At birth, pups weigh about 300-500 grams. [3] This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005). It is bigger than its canid family members like the fox, jackal, and coyote. Wolves typically stand about 32–36 inches (81–95 cm) at the shoulder and males weigh between 100 and 145 pounds (45–65 kg). Conception period normally lasts 62-75 days, and a female gray wolf may reproduce five to six pups; this usually takes place during summer. Gray wolf packs consist of about five to eleven members; these packs live and hunt together. The gray wolf is also able to survive in any environmental conditions as it has good adaptation skills. [10][11] More recent studies have reported the average range of height and weight in the north-west of the United States, both sexes were between 68 and 91.5 cm (26.8 and 36.0 in) tall at the shoulder. Its ears are also shorter, and its fur bushier. [1], According to one source, phylogenetic analyses of North American gray wolves show that there are three clades corresponding to C. l. occidentalis, C. l. nubilus and C. l. baileyi, each one representing a separate invasion into North America from distinct Eurasian ancestors. It likely crossed into North America through the Bering land bridge after the last ice age, displacing C. l. nubilus populations as it advanced, a process which has continued until present times. Along with C. l. nubilus, C. l. occidentalis is the most widespread member of the five gray wolf subspecies in North America, with at least six different synonyms.

Not much has been published on Canis lupus mackenzii but one of the most comprehensive studies was done in 1954 by W.A. The Mackenzie wolf also has thick elongated limbs that it uses for navigating through coarse landscape such as snow areas or the Rocky Mountains. Of these, about 12 percent of carcasses were scavenged by other predators, including ravens, bald eagles, black bears, grizzly bears, and coyotes. They measure 32 to 36 inches shoulder height and 5 to 7 feet in length, from the tip of the nose to the end of the tail. In a day, a Mackenzie wolf can cover about seventy miles because of its huge chest which holds up large lungs that are effective for respiration in elevated regions. Northwestern wolves are one of the largest subspecies of wolves. The Mackenzie Valley wolf can reach up to 175 pounds. (2011). By Vic Lang'at Junior on November 23 2018 in World Facts.

A male average gray wolf weighs about 88 pounds whereas a Mackenzie wolf averagely weighs 175 pounds.

[4], This wolf subspecies can be found in Thaidene Nëné National Park Reserve. Winter-weakened or sick elk also play an important part of Yellowstone wolf diets and it is estimated that over 50 percent of winter-weakened or sick elk in Yellowstone are killed by wolves. In comparison, the mean adult weights of its two nearest rivals in size, the Eurasian wolf (C. l. lupus) and the Interior Alaskan wolf (C. l. pambasileus), was reported as 39 kg (86 lb) and 40 kg (88 lb), respectively.

The northwestern wolf (Canis lupus occidentalis), also known as the Mackenzie Valley wolf,[4] Rocky Mountain wolf,[5] Alaskan timber wolf,[6] or Canadian timber wolf,[7] is a subspecies of gray wolf in western North America. The Mackenzie River wolf (Canis lupus mackenzii) is a subspecies of gray wolf which is found in Canada's southern portion of Northwest Territories. Wolves are also monogamous as they remain together until one dies.

They also will charge young calves separated from their parents. [15] In the same national park, wolves also prey on bison, though such attacks usually involve sick animals or calves, as bison can easily kill wolves with their hooves. [6], This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005).

The Mackenzie Valley Wolf measures 81-102cm (32-40 inches) tall at the shoulders and has a length (including head and tail) between 1.5 and 2.1 meters (~5-7 feet).
