You asked a nice question. There is an interesting site which talks about how wolves are tracked in order to know about their way of life. It would be good for you to click on the next link and have access to this site and look at the nice wolfs picture there.

According to the description in the site, wolves are territorial. Wolves live in packs and these packs usually consist of a group of 5-9 wolves. A male and a female pair who are unrelated are the dominant wolves. Each wolf pack has a specific territory (area of land) in which it hunts for food, raises its pups, and that it defends from other wolf packs.

Wildlife biologists know about wolves way of life by tracking them using radio telemetry. For instance, gray wolves live in the Superior National Forest in Minnesota and it is possible to know where the wolves travel, what they eat, how much they move around, when they rest, how many of them live together, and how often they come in contact with humans.

From other sources I found that red wolves prefer to live in forests, swamps and coastal prairies. Dens are often located in hollow trees, stream banks and sand knolls. Red wild wolves live through the south-eastern parts of the United States, from Texas to Florida. A population is being reintroduced to northeastern North Carolina, in the Alligator National Wildlife Refuge region. There is also a captive red wolf population distributed in 32 facilities across the nation.
