The thing about Canada geese for me is the weird little poos. I don't mind the aggression, the flocking behavior, or any of the other antisocial nonsense that they've adopted from their namesake country.
I do honestly love hearing the honking and watching them fly by. I always point it out to my kids. I've seen lots of Canada geese in my life and they've never hissed at me, so I don't have a problem with them other than the poops that are just everywhere.
I've been on walks in parks that got too close to someone's nest and been charged. Those maniacs have serated tongues and beaks. I'm not kidding. You don't want to be bit by these maniacs
