<<I am pretty sure that Canada also has badgers and wolverines, which are also vile-tempered critters.>>
Wolverines for sure; I think the wolverine must be the state animal of our Michigan neighbours, because I believe I've seen the state referred to as the Wolverine State and one of their state university teams is the Wolverines. I'd guess badgers as well, but the only badgers I've ever seen were in France - - a whole family of them crossing a country road at night caught in our headlights. Very easily identified by the unique shape of the head. One of the U.S.S.R.'s bombers during the Cold War was called the Badger. Must be a pretty dangerous animal, but as far as I know the wolverine is by far the more vicious. I was just watching a TV drama (maybe J.A.G.?) a few weeks ago about a U.S. pilot crashed down in the bush in wintertime, at one point getting attacked by a wolverine. Ugly as sin. Mean. It was kind of bullshit because after the guy rolled down a hill, the wolverine broke off the attack and just disappeared. That's not consistent with what I've read about them - - they don't give up.
