GRAY WOLVES<br />

What are gray wolves?<br />

Gray Wolves are large, wild canids native to the northern hemisphere. There are four widely recognized subspecies<br />

of gray wolves in North America: the Great Plains or Timber <strong>Wolf</strong>, Arctic <strong>Wolf</strong>, Rocky Mountain <strong>Wolf</strong>, and the<br />

Mexican Gray <strong>Wolf</strong>. Subspecies vary more by their range than by their physical characteristics.<br />

<strong>Wolf</strong> Packs<br />

Wolves are social animals that generally live in family<br />

groups comparable to human families. A family<br />

of wolves is called a pack, and typically has 7-12<br />

members. Sometimes wolf packs include non-family<br />

members, or “outsiders” who have solicited to join<br />

the pack. Although wolf packs have a strong social<br />

hierarchy, the pack structure can change over time as<br />

wolves age and move up or down in the ranks.<br />

Pack Structure<br />

The alpha male and female are the pack leaders.<br />

This couple usually mates for life and are typically<br />

the only animals that breed. Though both parents are<br />

responsible for pack cohesion, the alpha female often<br />

takes a stronger role in keeping the pack together.<br />

The betas are the 2nd in command. This group consists<br />

of subordinates, yearlings and pups.<br />

The omegas are the lowest ranking members of the<br />

pack. Packs often have both a male and female omega.<br />

Habitat & Territory: Where do gray wolves live?<br />

Gray wolves once lived across North America, Europe, Asia and North Africa, but have been driven out of most of<br />

their former range. The North American Gray <strong>Wolf</strong>’s range now includes parts of Alaska, the Great Lakes region,<br />

northern Rockies, Pacific Northwest and Canada. Gray Wolves live in diverse habitats including tundra, forests,<br />

prairies, mountains and deserts. A wolf’s territory is where the pack lives, hunts, breeds and plays. Territories<br />

range from less than 100 sq. miles to 1000 sq. miles depending on the abundance of prey and other predators.<br />
