It’s the nature of the wolf to travel. By age two, wolves of both sexes usually leave their birth packs and strike out on their own, sometimes covering hundreds of miles as they search for mates and new territory. Whatever the reason, when wolves move, they do it with intent—and quickly. Humans don’t know how they decide which way to go, but the choice is as important as any they’ll ever make.
