There's a story today from the Bozeman Daily Chronicle that a wolf may have killed a man in northern Saskatchewan.
Wolf attacks on human's are exceedingly rare and it appears this wolf may have been eating from a mining camp dump, which brought it in close contact with people and resulted in loss of fear of humans.
I found it interestingly absurd that the article mentions the dangers of allowing wolves to become habituated to humans and goes on to point out we shouldn't feed black bears, grizzlies, raccoons, deer or other wildlife.
