Geese aren't bullies at all. I ride my bike on paths that pass ponds and fields where there are a lot of geese. Geese will politely move out of the way almost every time I encounter them. You can't get this sort of behavior out of joggers, dogs, or children. Bells and horns won't work. Geese just know what to do.

I have not encountered more civilized and well-mannered birds than Canadian geese. Their manners more than make up for their pooping everywhere.
