What sound do Canadian geese make when they are mad?

"UH UH UH UH" the geese goes.

its mate goes "OHHHHH YEAH BABY!"

Canadian Geese will look you in the eye first and let out a loud honk. If the goose continues to be agitated it will flatten out its neck until it is almost parallel to its body and emit loud, short, frequent honks. If this should happen remain calm and slowly back away but do not run. If you run, the goose will pursue.
