I was curious, so I did a little research. In the United States, an estimated 55 people are killed by lightning, 21 or so people are killed by avalanches, and 17 by hurricanes each year. Bruins (bears) kill around one person per year in the U.S., less than one death by shark or panther (mountain lion) happens in the U.S. annually, coyote attacks are incredibly rare and I can't find a single reported death by duck, penguin, thrasher or the ever-frightful maple leaf.

So congrats, Bolts - it looks like you're the NHL's most prolific killers (of course, it could be argued that Senators killed more than 800 Americans last year, but we needn't go there).
