A very old man for a wolf
From Outside magazine and www.outsideonline.com:
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.
One day in 2005 or 2006, a young, black-furred wolf in Idaho decided to head west. He swam across the Snake River to Oregon, which at the time was beyond the gray wolf’s established range. By entering the state, he walked out of anonymity and into a form of local celebrity, becoming notorious over the next few years for his bold raids on livestock and his enduring competence as a hunter, father, and survivor.
