[3] This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005). 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.
Gray wolf packs consist of about five to eleven members; these packs live and hunt together. However, dispersion could be influenced by sexual maturity or little food that cause competition among members or. These subspecies include Great Plains (c.l nubilus), Arctic (c.l arctos), Eastern Timber (c.l lycaon), Mexican (c.l baileyi), and the Northwestern or Mackenzie Valley wolf (c.l occidentalis), which is the largest among all. 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. 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).
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. Interestingly, pups are born blind and deaf and only start to see after nine to twelve days. [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. Besides its large chest, which also enhances balance, the wolf has a large neck that supports its big head that it uses during hunting. More recent studies have reported the average range of height and weight i…

Its ears are also shorter, and its fur bushier. Fuller, Wolf Control Operations, Southern Mackenzie District, Canada Wildlife Service Report. 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. [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.

In Yellowstone National Park, adult females were reported to average 46 kg (101 lb) and adult males averaged reportedly 62 kg (137 lb), with a mean adult body mass in winter of 46.4 kg (102 lb). C. l. occidentalis, the most northwestern subspecies, is descended from the last gray wolves to colonize North America. 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.

[6], This wolf is recognized as a subspecies of Canis lupus in the taxonomic authority Mammal Species of the World (2005). It is mostly found in isolated areas of Eurasia and North America. Fuller, Wolf Control Operations, Southern Mackenzie District, Canada Wildlife Service Report. It is bigger than its canid family members like the fox, jackal, and coyote. [4], This wolf subspecies can be found in Thaidene Nëné National Park Reserve. A male average gray wolf weighs about 88 pounds whereas a Mackenzie wolf averagely weighs 175 pounds. In terms of appearance, gray wolves have thick bushy furs that are mostly grey, however, wolves with white, brown, black, and red furs also exist. Currently, the existing number of gray wolves in the world is approximately 300,000. He chose to give it the name occidentalis in reference to its geographic location rather than label it by its color, as it was too variable to warrant such.

It is sometimes known as Alaskan, Canadian, or Northern Timber Wolf; this is because it is widespread across Alaska, Mackenzie River Valley, Canada, and parts of the northwestern United States.
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 Valley Wolf has a specialized body that has made it one of the world's most efficient hunters. The gray wolf, scientifically known as Canis lupus (c.l), is the largest existing member of the Canidae family. 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).
The Mackenzie wolf also has thick elongated limbs that it uses for navigating through coarse landscape such as snow areas or the Rocky Mountains.

It ranges from Alaska, the upper Mackenzie River Valley; southward throughout the western Canadian provinces, aside from prairie landscapes in its southern portions, as well as the Northwestern United States. They are the most popular and well-known animal as they have been studied and written about in most books than any other animal species. Northwestern wolves are one of the largest subspecies of wolves. At birth, pups weigh about 300-500 grams. [9] In Yellowstone National Park, adult females were reported to average 46 kg (101 lb) and adult males averaged reportedly 62 kg (137 lb), with a mean adult body mass in winter of 46.4 kg (102 lb).
