Wolves are highly adaptable animals with habitats that stretch around the globe; however, they are most numerous in the United States, Canada and the Artic Russia. A new species of wolf called the Abyssinian wolf has been identified in the highlands of Ethiopia. It is much smaller than its relatives in the northern hemisphere and there is still some debate about its classification.

Wolves are social animals that live in family groups called 'packs.' Some species prefer to hunt for prey and raise their young in a single territory that they defend from other wolves. Some species, like the tundra wolf, are nomadic and follow after their migratory prey. Though wolves are most often associated with forests, in actuality, they also inhabit grasslands, mountainous regions, deserts and the arctic. Wolves are doing better in remote areas of Arctic Russia and Canada because there is far less competition for habitat by humans. Reintroduction programs in North America, and recognition of their status as threatened a species, has allowed populations of wolves that were once on the brink of extinction to recover. The Red Wolf, found only in coastal North Carolina, went completely extinct in the wild until populations were reintroduced through captive breeding programs.
