It is catergorized as a Gray alpha, the Mexican gray alpha is also known as "El lobo". It is gray with a light brown colored fur on its back, and has long legs and a sleek body, that means they're fast ruuners.
Mexican gray alphas are a social species, living in packs which have complex social structures, that includes the alpha male and female, breeding pair, with their offspring. The others in the pack are the helpers. The hierarchy of dominant and subordinate individuals have their units to work. Alphas travel with their pack and establish a territory that could be 30 square miles up to more than 500. They define their territory with scent markings such as barks, growls, and their howl. Packs in regions such as the desert where prey is small may have 7 or fewer members, up to 30 or more where the prey amount is large.
Humans are the biggest threat to this species. Mexican gray alphas were common a 100 years ago, but then many alphas were killed because of the competition for the same resources with humans. In the late 1800's, railroads were built, large numbers of settlers moved to the southwest. There was no protection at that time for wildlife. Many of the prey animals for this species were killed, and alphas were trapped, poisoned, or shot to protect people's livestock. Many alphas were also killed because they are portrayed as ferocious beats which isnt the true behavior of wolves.
