This Canada goose was having a hissy fit. I've warned parents of small children not to run up to them, as they can begin to hiss, lower their head and "charge". The little teeth lining their beaks can give you a nasty bite. I've heard of people being killed by swans, and I can see it happening with these creatures. Like rats, like crows, like raccoons, they thrive everywhere and make a nuisance of themselves, ruining farmers' crops and making great piles of doglike do-do.
