Gray wolves (Canis lupus):
- Typically live in packs of 6-10 individuals, but can range from 2 to 35 wolves.
- Larger packs tend to occur in areas with abundant prey and low levels of human activity.
- In exceptional circumstances, very large packs of more than 50 wolves have been recorded, but these are relatively rare.
Arctic wolves (Canis lupus arctos):
- Typically live in smaller packs of 2-12 individuals due to the more dispersed distribution of prey in Arctic environments.
- Pack sizes can vary based on the availability of food and the presence of other predators in the area.
Ethiopian wolves (Canis simensis):
- Form small, closely-knit packs ranging from 2-6 individuals, with occasional larger packs of up to 15 wolves.
- Their smaller pack size is influenced by the scarcity of their primary prey, small rodents, in their high-altitude habitat.
Mexican wolves (Canis lupus baileyi):
- Historically formed packs of up to 8-10 individuals, but due to population declines and habitat loss, contemporary Mexican wolf packs are typically smaller and may consist of 2-4 wolves.
Red wolves (Canis rufus):
- Usually live in packs of 4-6 individuals, with occasional larger packs of up to 12 wolves.
- Pack sizes are closely tied to the availability of suitable den sites and prey resources within their territories.
It's important to note that these pack sizes are generalizations based on observations and research. Some wolf packs may deviate from these numbers due to specific regional conditions and ecological factors.
