Interesting facts about our duck friends

Did you know that ducks have regional accents? If you saw ducks in different regions and heard them quacking to each other, you could hear that every quack they made was different! It depends on the regions, even we have different accents in our regions.
Maybe they have some slang as we do or some quack words (our swear words). I mean even they get angry sometimes. Who doesn´t? In such a situation no one can handle it right. Even the  coolest duck on earth!
